Using Seawater for Air-conditioning

In today's "Business of Green" special section, I write about how Lockheed Martin and other companies are exploring an early-stage technology to generate electricity from the ocean. The technology, called "ocean thermal," uses the temperature difference between warm surface water in the tropics and the ocean's chilly depths to make power.One important (and expensive) requirement is a giant pipe to pump the frigid water up from deep below the surface. But once the cold water is brought up, there are additional uses for it, as several experts explained to me.At around 40 degrees Fahrenheit, chilly seawater can be used to air-condition buildings. The seawater "can chill fresh water in a heat exchanger or flow directly into a cooling system," according to the Department of Energy.The technology is already in use at Cornell University, where cold freshwater from a nearby lake is put through a heat exchanger to help cool buildings on campus and at nearby Ithaca High School. Similar projects are operating in Toronto and also in Sweden.Hawaii has used cold seawater to air-condition a few buildings at the Natural Energy Laboratory of Hawaii Authority on the Big Island. The lab "has been saving up to $4,000 per month since it switched its three buildings to deep seawater-based cooling," according to its Web site. Hawaii needs air-conditioning year-round and is working on a seawater air-conditioning system for downtown Honolulu.But there will be challenges."Obviously you've got to do some pretty extensive pipelines," said Theodore Peck, a Hawaii energy official. And the technology, Mr. Peck pointed out, only works for centralized air-conditioning systems. It "doesn't work for high-rises with individualized air-conditioning units," he said.Comments are no longer being accepted.I don't speak english, but in the line to convert two diferent surfaces in a source of electric power... I have one solution, in a diferent way.unfortunally it's in spanish. If someone speak spanish could read this site //!Think of all the fish and other sea creatures that would get sucked into these systems to die.My concerns with this technology would be with the method of sea water intake - possibly pumping in unwanted plankton and micro organisms. Then there are the long-term issues with clogging and overall maintenance of this type of systemThe other concern is where all that "heated" sea water goes; is it pumped back to the same depth (another energy cost) or is it simply pumped to the surface. How will this heat exchange affect the sea life?Is there any concern for the aquaitc life that may depend on the thermocline remaining stable? Whilst this may not be so much of an issue in the ocean models, I wonder about smaller lakebound installations acutally homogenizing their thermal profile, and making some forms of life threatened.To point out the obvious-sure it will work for individual units in high rises, it will just be more expensive because the water needs to be pumped to each unit.Tap water is usually about 50 degrees F. It is already running through pipes in the ground that act as a geothermal heat pump. And, the pipes are already paid for and connected to each building. Use that!This sounds like a really coool idea!!!While this may work well in some applications, your view was too narrow as it does not address the effect of returning the heated water to its source. Many studies and much documentation exist regarding damage to flora and fauna caused by thermal pollution, so without taking this into account, don't be too quick to trumpet the heating of waterways and ocean water.Before we ship cold water out of the depths of the ocean on a wholesale basis, have any studies been done on how this will affect ocean currents or disrupt sealife? We once thought the oceans were infinitely large enough to dilute our pollutants, now we know how wrong we were.*Everything* we do has side effects. Ocean thermal cooling and power generation are among the least obtrusive technologies.The suggestion about using potable water as a heat sink is very interesting. Even in a hot climate the amount of heat used to make hot water for an average household is by coincidence roughly comparable to the amount of heat moved out of the house by the air conditioner, so that water would be a useful heat sink. In other words, if the water going into the water heater were first run through a storage tank pre-heater that was connected to the air conditioner, the air conditioner would do less work (because it would be pushing heat into relatively cool water rather than into hot outside air) and much less energy would be needed to heat the water to its final termperature. This could be done in many central A/C systems, even as a retrofit.This technology has been around for a long time. It was being investigated for use in generating electricty (O-TEC- Ocean Thermal Energy Conversion) in the '70's at The Stennis Space Center on the Miss. Coast near Pearl River.Jim,Most places do not allow tap water or residential well water to be returned directly to a well or water mains because of possible contamination. In some cities, like NY, that water isn't going back upstate either!This prevents many people from using inexpensive geothermal, as they're then faced with drilling wells, digging up a lot of ground, etc.Beyond that, consider that, if you're cooling a building or a town, you're heating that lake or ocean bottom. It could be a bad idea. Remember that power plants that use river water for cooling have significant thermal environmental impact, in addition to sucking up fish.Actually, up to the 1950's at least, tap water heat exchangers were used in residential construction for compressor-less air conditioning on houses that had hot air furnaces. The 'A frame' radiator was simply hooked to the water, and that's all there was to it. Worked, but of course, wasted water.I think this might be useful on a small scale for remote locations where power would otherwise be difficult to acquire.However, on a larger scale this could pose more problems than solutions. The first issue is how would this effect the ability for water to sequester CO2. It is this deep cool water that keeps so much of this green house out of the atmosphere. Also, the difference in temperature between hot and cool water at the surface and below helps drive ocean currents and provides the climates that we have become accustomed to. For example, the thermohaline circulation that drives warmer saltier water from the Gulf of Mexico towards Europe keeps that continents climate more hospitable. As that water cools off, it gets denser and it sinks taking CO2 deep down with it.These are just a couple issues that I didn't see mentioned in this article. I think all green technology needs a review before it gets implemented in large scale projectsSo many ways to generate power - using thermaldifferences. Thermocouples have been used for a hundred years or more. Tne there are concentration difference used by the Israels in the Dead Sea. Nice to see, among the examples in: // Germany automakers Volkswagen and BMW have developed thermoelectric generators (TEG) that recover waste heat from a combustion engine.According to a report by Prof. Rowe of the University of Wales in the International Thermoelectric Society, Volkswagen claims 600W output from the TEG under highway driving condition. The TEG-produced electricity meets around 30% of the car's electrical requirements, resulting in a reduced mechanical load (alternator) and a reduction in fuel consumption of more than 5%.BMW and DLR (German Aerospace) have also developed an exhaust powered thermoelectric generator that achieves 200 W maximum and has been used successfully for more than 12,000-km road use.Space probes to the outer solar system make use of the effect in radioisotope thermoelectric generators for electrical power.But if Lockheed gets in the business it's news?"Hawaii needs air-conditioning year-round..."Err... And why is this, exactly? Surely people who move to Hawai'i do so because they want to live in a warm, tropical climate. So as soon as they get there, they think they need to air-condition everything? Seems like the real problem here is more psychological than technical!And an important point for those who've mentioned using cold ground water for cooling as an example of "geothermal" energy. It isn't: it's ground-source. Geothermal implies that the energy is coming from some underground energy source such as a hot spring or geyser.I am disturbed by how little science fiction today's inventors- and commenters- read.The concept of deep ocean heat-differential use has been around for a LONG time, and kicked back and forth in science fiction extensively. For those not familiar- good "hard" scifi consists of complex "thought experiments".Yes, the impacts on life and environment have been thought about, quite a lot. One thing they missed here- typically enthusiasts for piping up cold sea-bottom water point out that dumping it at the surface will mimic an "upwelling" of nutrients; like those that drive the world's largest fisheries. Maybe.My favorite was Arthur C. Clarke- who suggested that deep sea giant squids might well resent the intrusion of "hot" materials into their world- and would routinely rip them out.Here is an example of residential use // there, I know i am late on this article but I just recently heard about this Sea Water Air Cooling/Conditioning system as they are implementing it here in Polynesia.I don't get it, how come they do not need any kind of autorization before this huge implementation all around the planet ... This is the saver of the planet they nearly call it.Pumping cold water (4degres celcius) at 600m deep like crazy and rejecting this water at 20-24 degres celcius at 50m deep cannot be good for our ecosystem, even more when it's done on a large scale basis which is the case (La rÃunion, Polynesia, Scandinavia, Hawaii, USA, Canada, Emirates now ... and we talk about danger of temperature increase of our ocean related to the presence of methane Hydrates ? Are we blind, stupid and suicide orientated or what ? Anybody can give me a clue ? Do I mistake somewhere?

Energy Saving Tips for Air Conditioners - Yahoo
Summer is here and if you just can't stand the blistering heat then turning on the air conditioner could just be your best option. Sad to say, comfort does come with a price. Unfortunately, as humidity rises so as our electric bills. To keep our energy consumption and bills as low as possible, here are some energy saving tips for the use of air conditioners.Close the doors and windows - make sure to keep all windows and doors closed to keep the cool air in and the warm air out. This will also help the unit not to work double time just to maintain the cool temperature inside.Check and clean your filter - always make sure to check and clean the filter of your indoor unit regularly to maintain the unit's efficiency.Use it only when you need it - Cool the air only when necessary. If you decide to keep the unit on while you're away, make sure that your windows and drapes are closed and turn your unit up to 80-85 degrees. It is also advisable to program switch-on times according to your personal usage profile.Switch off sources of heat - there are other appliances like ovens, lights, computers, no name a few that consume power and give off heat. Turn these appliances off when you're not using them. Your unit's thermostat senses the heat that can cause your air conditioner to run longer than necessary. This will increase energy consumption.Turn your AC down at night - the perfect time to turn your AC down is during late at night because you don't need the same level of conscious cool and it also gives your air conditioning system a rest.Use the fan - to keep things cool, we rely too much on air conditioners but having a supplemental fan as a back up would be a great idea in reducing energy consumption. Turn your AC off when the air is cool outside then use them to remove heat from your home and to circulate the cool air.Have your air conditioner unit checked - basic maintenance is what your air conditioner needs. Have it checked annually by a specialist to make sure it is working at peak efficiency.Control humidity - to ensure humidity control, avoid having long, hot showers, mopping the floor or drying laundry because these things keep raising the humidity in the room. The best time to do these things is during the evening. To speed up the dehumidifying process without consuming a lot of energy from your AC, manually switch the ventilator to the lowest setting.
We Like to Take a Cruise Vacation but We Have a Problem with the Air-conditioning?
The air conditioning on the more modern ships is controlled by the occupants in each cabin. If yours does not seem to be adjustable, call the front desk, tell them you will quite literally get sick if it keeps blowing so high, and ask them to have it repaired. They do NOT want people getting sick! Beyond that, have your cabin steward grab a couple of extra blankets for you. I was once on a ship where the air conditioning in our cabin did not work and it was over 90 degrees, and the guys who came to repair it shrugged and said too bad and left. Not good enough! I went screeching down to the purser's desk, complained, and told them that I happened to know that there were engineers on that ship who could repair anything, and that it was not like they went home at night or went on vacation. I also told the clerk that I was absolutely certain that if the air in the cabin of the Captain or any other senior officer were not working that it would be repaired properly and promptly. And the chief engineer came almost immediately to the cabin with two other folks, and they fixed it.1. My central air conditioning unit has stopped working. The thermostat works but the air blows out luke warm.?The problem could be one of many. The first thing I would look for is a bad capacitor in the outside unit. It is silver and usually oval shaped. If the top is swollen then it is bad. The third thing could be a bad fan motor. Make sure that you turn your power off to the unit before opening the outside unit up2. Why does my car overheat when I turn on the air conditioning?Make sure if it has two fans that both fans come on with the AC3. My girlfriend's 1989 BMW's air conditioning stopped blowing cold air--fan still works---if it's not...I do not know but the same thing just happened with my 92 Mazda 929. Try getting on the highway and getting your RPM's up and turn it on. If it does not work after that, then you might have the same problem I do.4. Why does my car's air conditioning vents blow out the smell of gas fumes sometimes?ANY time you smell gas your right you have a gas leak. Get it fixed. The small sparks the blower motor for your climate system could set some flames off right in your face. I like the picture you chose for your ID. you might see ghuys with that hat on all around your truck soon5. Is Australia really hot, as in unbearably hot? Or is it dry, windy, still bearable all year round without air-conditioning and not humid or sticky like other Southeast Asian countries like Malaysia, Singapore, Indonesia?Here is Victoria today:Snow falls in Melbourne, Victoria and Tasmania as icy weather blows in6. Air conditioning problem in a Dodge Ram 1500, 2003 model.?yep have a 2002 Dodge ram replaced the ac condenser fan and it works great. the trick was when i removed the battery and the battery mount that left plenty of room to remove old fan after i moved the fuse box to where battery sits and to remove battery mount you have to remove dirt guard around front left tire. Also the new fan and old fan you have to cut off a little piece of plastic where the top condenser pipe goes thru the shroud. But wow after you replace it 80. 00 later and a little sweat it works awesome7. Is it possible to live comfortably (year round) in a house or apartment in Beverly Hills, CA that does not have air conditioning?First, there must be very few apartments in Beverly Hills without A/C. It is a high rent area and those residents would demand (and get) quality air conditioning.Of the homes and apartments in BH that I've been a guest and the home my wife and I shared Beverly Hills PO, not one of those abodes was without A/C. My novel, INSIDE MOVES talks about some of this (not A/C) in early Hollywood (it's only on the other side of Sunset Boulevard) and homes built in Beverly Hills and surrounds.I hope that answer was helpful. My suggestion, rent next door in West Hollywood. Better deals, nice folks and A/C will be included. Good luck!.
8 Ways to Trim Your Summer Electric Bills
During hot summer weather, heavily using air conditioners, humidifiers, refrigerators and other home appliances can catapult home electrical bills through the roof. In most regions, power companies charge for electrical usage on a tiered basis -- the more power you use, the higher the rates you pay. During any given month, once you use up your allotted baseline amount of electricity, the cost for additional power can double or triple. A key money-saving strategy is to clip off excess usage.[Read: Home Improvements That Hurt the Value of a House.]Here are eight ways to save now:Be Smart With Air ConditioningAir conditioning is the monster lurking behind devastating summer electric bills. Chill your bills by using less AC. By turning your thermostat up to 78 degrees Fahrenheit or higher, you can save a bundle. This doesn't mean you have to live in a hot house. As discussed below, there are numerous ways to make your home feel cooler without AC.Dirty forced-air system filters restrict air flow, reducing the AC system's efficiency. Change or clean your AC system's filters at least twice a year to ensure peak air conditioner efficiency.Don't pay for cooling when you're not there to enjoy it. If you don't already have a programmable electronic thermostat, install one. You can eliminate wasted energy by setting it so room temperatures automatically rise a few degrees when you're sleeping or away, and then cool down when you're moving around at home.Similarly, don't waste money by chilling rooms unnecessarily. Close the registers in an unused guest room or other spaces not being used. Just be aware that closing registers can create an inefficient imbalance in the system, so check with a heating and cooling contractor if you want to close off more than a couple registers. Be sure to shut the doors to those uncooled areas, but don't close off a room if the system's thermostat is located in it.Over time, the ductwork that delivers cooled air throughout the house can leak expensively chilled air, especially at the joints where sections connect. If you suspect that your ductwork could be leaking, call an HVAC pro or duct-cleaning company to check, clean and repair the ducts.Open Windows at NightUnless you live where nights stay hot and humid (or where it isn't safe to leave windows open), keep the house buttoned-up tight during the heat of the day and, if you have air conditioning, run it. Then at night, turn off the AC and open up the windows.To manage this strategy, you'll need an outdoor thermometer placed in the shade and an indoor thermometer located in a room you use. When the outdoor temperature drops below the indoor temperature, turn off the AC and open the windows to expel hot interior air and draw-in cooler outdoor air. Placing fans in front of windows and doors can help boost ventilation.Don't be tempted to open windows before the outdoor temperature drops below the indoor temperature. Though you might feel a breeze near an open window, you would actually let hotter air into the house.In the morning, close windows and doors before outdoor temperatures rise.Note: This technique doesn't work well in high-humidity regions because the AC must work long and hard to dehumidify the air repeatedly.Keep Interior Air MovingWhen the air is moving inside your home, room temperature will feel 2 to 3 degrees cooler than when the air is still. If your home has ceiling fans, turn them on to get the air moving.Also turn on your thermostat's fan switch. Regardless of whether or not the AC is running, the system's blower will circulate air throughout the house, creating a comfortable breeze and balancing temperatures from room to room. Turn it back off when you intend to leave the house so the system's blower motor doesn't waste energy.Be sure air can flow freely through the forced-air registers and into the room, and back through the system's return-air register. Registers should not be blocked by drapes, furniture or anything else. Keep doors between cooled rooms open so air can circulate freely.Employ attic fans to ventilate super-heated air from the attic. If you don't have air conditioning, consider installing a whole-house fan to extract hot air and draw cooler air through the entire house.Reduce HumidityHigh humidity makes the air feel warmer; low humidity makes it feel cooler. Much of what an air conditioner does is remove humidity from the air, making it feel cooler. You can cut down on the air conditioner's work by minimizing activities that create humidity, such as washing and drying clothes and cooking. Run ventilation fans when showering and cooking, but don't overuse them. Turn them off after use to avoid expelling AC-cooled air from the house.[See: 9 Outdoor Living Renovations to Splurge on This Summer.]Avoid Heat GainYou can run air conditioning and fans less if you prevent the house from heating up in the first place. Block direct sunlight by pulling drapes or shades, and consider applying heat-reflecting window films to sun-facing windows. For the long term, consider planting trees or installing awnings to help prevent solar gain through windows.Inside the house, avoid using heat-producing appliances such as the oven, range and clothes dryer during the day.Use Electrical Appliances LessAppliances that produce heat are a double-whammy: Not only do they give off heat when you use them, but they consume a lot of electricity. If you have an electric dryer, only run it with full loads. If you have an electric water heater, turn the water temperature down to below 120 F.Swimming pool pumps are big energy gobblers. If you have a pool, adjust the timer so the pump runs just enough to keep your pool's water clean and clear.As your appliances wear out, replace them with Energy Star-certified, high-efficiency appliances for long-term savings.Use Lighting LessBecause of summer's long days, you should be able to cut back on the need for electric lighting. Like appliances, light bulbs create heat and use energy, so use them less and consider switching to LED or compact fluorescent bulbs.Outdoors, use solar-powered or low-voltage lighting on timers. Equip security lighting with motion sensors to minimize wasted energy.[See: 10 Ways to Save Energy and Reduce Utility Bills at Home.]Weatherize Your HomeLast but not least, consider making long-term energy efficiency improvements such as weatherstripping windows and doors, caulking siding, replacing windows and upgrading insulation.To identify the best improvements for your home, consider hiring a professional home energy consultant to do a home energy audit. This typically costs from $200 to $500. According to the Department of Energy, you can save from 5 to 30 percent of your energy bill by making home energy upgrades. Or you can do your own home energy audit, following instructions available online or by using a do-it-yourself energy audit site such as HomeSelfe.Don Vandervort is the founder of Vandervort is the founder of a leading home improvement advice site. Don has authored many home improvement books, written extensively for and served as a segment host on HGTV.
Should My Roommates and I Turn on Central Air Conditioning Or Get 3 Window AC Units?
3 5,000 btu air conditioners would be a lot cheaper and can be left on energy saver so the ac does not keep jumping on all day.just make sure they are 110volts1. How can I cool down my apartment without turning on the air conditioning?I would suggest finding reflective material to cover windows that receive the most sunlight. And turn off unnecessary appliances that put off heat such as game systems, computers etc. Have alot of candles lit? I tried this fix and as little heat as these things put out it seems petty but every little bit helps.2. Do FHA loans require air conditioning and/or heating units to get the loan.?You will have trouble getting any loan for this house, FHA or no FHA. The house has to be livable to get approved. This one is not. It has to have a heater, hot water heater, stove and oven. This house is only available to cash buyers or investors. You need to move on. FHA does not cover construction loans, and that is the only loan you can have w/o a certificate of occupancy.3. Did you ever wonder how people back before air conditioning could function? Were they better...?...even though I grew up in hot, humid summers without A/C. We used fans--window fans, floor fans, heck even silk fans... and city folk made ample use of fire hydrants. When people look at how average US longevity has increased over this past 1-2 generations, most will credit advances in modern medicine--in particular prescription drugs. However, I think A/C is an unsung hero. I think there were a lot more heart attacks and strokes because of the heat. People died at a much younger age. I think you are right, though, in that people learned to live with the heat and humidity. It does not mean they preferred it. It just means they did not fall apart if their shirts soaked through. Remember, the dress code back then was more conservative. Try wearing a 3-piece suit with a tie and heavy shoes on an un-air conditioned NYC subway ride Downtown. Hey, I used to do that. The temperature in the cars sometimes rose well above 100 degrees. With passengers packed in like sardines, it was rough. By the time you arrived at work in the morning, you looked like it was 7pm... So, here's a toast to air conditioning. May its inventor continue to be rewarded in heaven...4. please HELP!!! I need ideas on how to keep my house cool with NO AIR CONDITIONING!?Take a cold wet towel (after you wring it out) and place it over the grill of a floor or table top fan. Turn on fan and it will give cool air5. who makes more a year a Air-Conditioning and heating tech or a Motorcyle Mechanic?I have my own shop and I dont just turn wrenches,I build at least 4 or 5 custom choppers a year.I can make about 60 to 75 K a year without selling the bikes I build and a little over 100K with them. And as usual Bart is telling a complete B. S. story. Yesterday he E mails me asking about a bike thats gettting no spark and could it be the starter motor! As if the starter motor has anything to do with the ignition curcuit!6. What is the best way to prevent high cost air conditioning repairs?Have it cleaned once a year, change filter every month or two & do not buy those cheap filters you know the blue ones with the brown cardboard frame7. If i use the air conditioning in my car will it use some of the gas or will it use the battery power?The ac unit is driven by belts and compressors. There is some toll taking on fuel economy because your engine works a little harder to turn the compressor. Its really boils down to what comfort level you can live with. Since your altenator recharges the electrical system there is really no draw on the battery.... d8. Is it cruel and inhumane punishment to house prisoners in Texas prisons without air conditioning when its 110?Our soldiers walk around in 110 degree heat, wearing body armor, 60lbs of gear, getting shot at in Iraq and Afghanistan. They do it voluntarily. There is no air conditioning on a desert berm that they are using for cover. Why should prisoners have it any better? I say we get rid of the prison buildings. Make them just stay in cages. Give them MREs and water, and a sleeping bag. That's all the soldiers get
Do American Battle Tanks Have Air-conditioning...?
no they dont have ac it burns up in there1. Poll: Would you rather permanently give up heating or air conditioning?UK does not need a/c anyway2. my car's air conditioning stopped working, but comes back on occasionally?That could possibly be a short in the wiring3. Is it dangerous to drive my car in summer, with no air conditioning and the windows unable to open?Do this; it actually works, and it cools the car faster than opening windows does: 1. From before dawn until you are ready to start driving, keep the windshield and rear window covered, to keep out the sun (or park in the shade). 2. Some time before you are going to start driving (an hour should be enough to help, all day is better) , open all the doors, and let the wind blow through the car for awhile. This will cool it down to only slightly above the outdoor temperature. If it gets hot again while you are driving, then park somewhere safe, open the doors again, and cover the windshield and rear window again, and wait for it to cool. You have to plan where you park. It is not safe to have doors open when parked on the side of a street that has fast traffic. You need to park in your own driveway, in a parking lot, or at the end of a dead-end street or the end of a cul-de-sac. Ideally, you park in a garage, in a carport, or under a tree, to minimize sun.4. Is it bad to turn on or off the car with the air conditioning on? I have remote start...?I dont know why its bad, but my dad allways remind me to turn off the A/C before shut down the car,5. Why does my dog like to sleep under the air conditioning vent?dogs cant sweat as such they got 3 ways too cool themself, through panting/leting out hot air, through drinking water, or too seek a cool place6. Do I need to turn off my air conditioning before shutting off my car? I have a manual climate control system.?i've always heard its a good idea to turn your ac off. It puts less strain on your car when its starting up. Because its not having to engage the compressor along with everything else. I've also heard it can prolong the life of your compressor ect ect7. No air conditioning for a two day car ride. How can my family stay cool?Roll the windows down and get neked , and you might want to drive only at night8. Can someone give me an estimate to fix a leak in my Auto Air conditioning?figure on 13 or 1400 dollars9. Is there a product that I can add to my car's air-conditioning system that will seal a leak in the compressor?No there is not . Get two or three other estimates and do not waste money on the gas10. 2001 Dodge Ram 1500 4x4-Air Conditioning Not Working.?first off, stop leak wo not fix anything. there is a low pressure cut off switch that shuts compressor down whe freon is low, located in the line with a 2 wire conector, unplug it and jump across it, then fill system, as for the leak look for oiley spots, on your truck, look at condenser, on the Dodge a lotta leaks are there, the 2nd place, the evaporator coil, 90% of the time they leak, with a leak detector look at the drain hose,if you put tracer dye in system, it should show up, if it needs an evaporator coil, have someone do it, if your not experienced, there not bad to do if you have done them before. also you may need to check the oil in the compressor when the system is discharged, hope this helps a little.11. iam stalling a heating & air conditioning system and i have three brands options carrier , trane or bryan?If these are your only brand options trane is a good solid system, only be aware there are several different models to chose from. Assuming you are replacing an existing system ask about the deluxe models 14.0 seer and above., also consider the new freon R-410A.
Is There a Way to Clean Molds, Spores, and Pollen From the Air in Your Home That Is Truly Effective?
You can buy electronic air cleaners that attach to your furnace or central air conditioner. They take everything out of the air with washable electrostatic air filters. They also have conventional and or HEPA filters. But such a system will run you a couple of grand. There are also such stand alone systems.1. what's wrong with my (central) air conditioner?The bushings interior the motor are drying out.close the ability off,take the panel off and spray wd-40 on the decrease component to the shaft and manually spin it.placed the panel back on and initiate it up and you are able to nicely be waiting to purchase some extra time till finally you replace the motor. good success. incredibly saturate it with wd-40 and it will in all threat paintings2. How should I best keep-up my heart-rate and for how long to exercise EFFECTIVELY?look; i am just some wet dream with bankable assets, who prances around at nite letting social dysfunctionals stuff their paycheck into my i will give you the choice: either more pop science BS, or empirical knowledge that's older than you will be getting. It's like this: pop science tells us the half truth that the heart is a muscle, therefore exercise will make it stronger... the other half of that truth has to do with wear and tear, over time and from excessive usage. If you have enough sense to realize the human body is a finite organism, with a limited span of growth, maturity and declination, then you know that with age, the heart can only get...older. Pop science tells us exercise that elevates the heart rate is good for us; the other half of that truth is: most any exercise, even lifting a fork, elevates the heart rate, and insofar as optimum level, there is none. There are also no known conclusive tests to suggest your life will be longer cuz you ran yourself silly...the people they were going to showcase as the poster children for that claim have died: Flo Jo, Atkins, Skinner...need i go on? effective exercise is anything you do that shows improvement in overall health. Walking is known as the most effective. Smarter people like swimming, which gives a total body workout, without overheating and feel more fatigued after a good swim workout, cuz you were able to do more, without being sidetracked by sweating..the water dissipates the body heat, and allows the heart to do more important things for your body , besides playing central air conditioner. Empirical knowledge suggests, meditative, slow, deliberate exercise is the key to longevity,...3 billion asians and 3000 years of proof are hard to ignore, unless you are from the west. but enough of my jibber....the time has come for you to devise a plan that you can use for life...the rest of it. why set yourself up for injury by running? Walk. A brisk paced walk of five miles a day, at 15 minutes a mile, will do more for your heart than running, without causing shin splints, pulled hamstrings, cramps and milk acid seizing. if you are the horse, or at least the jackass you claim to be, forgo any macho buff gym weight need to bench press 400kg, and curl 120kg dumbells to show you stand up to urinals: your focus is on tone and sculpt, not bulk and 55, whatever you build in bulking up now, will start to fade; at 60, your just another has been wannabe with tittays. 20lb dumbells are your friend, ..your best friend ever.. 20 reps, three sets : for curls, reverse curls for triceps, overhead press, flies, , and you can look like any pic in any ad on the net, that pushes men to use supplements for ripped bodies.... body weight exercise is the core of a program for your age group...that means: pushups, situps and pullups, all in good form. Very few men at fifty can boast doing 10 pullups from a dead hang to the chin...oh, and that means dead hang, not arms half ******, halfway done and back up again, cuz your shorts are signalling failure. get up to 200 situps daily, 60 pushups in 3 sets of twenty, and 3 sets of 5 full pullups..that workout is about a half hour to 45 minutes with dramatic results. father , grandfather and great grandfather were able to do this stuff past 80....known advice.
I Have Changed the 35 Amp Fuses at the Box near My Central Air Conditioning System, still the Fan?
there is an access panel on the side of the outside airconditioner. pull it off. with a volt meter, see if it is getting power on the two big wires coming in to it. there should be 220 volts. if it is getting power, your unit needs work. if it is not getting power, you have an electric problem somewhere between the unit and the breaker box. after you check that, holler at me on yahoo messanger and i will give you more things to check. we should be able to pin point this problem.1. Air conditioning kicks off and on and it is very hot HELP 10 pointsDo not rush into things. That's the worst thing you can do, because as soon as you rush into something, headfirst, without thinking things through, that is when you will run into issues and regrets. And you do not want that. The best thing you can do in this situation is to think things through. Think about both girls, and how they make you feel. Having your best friend as a girlfriend can be fantastic, because she already knows you, and you can share so much with her. But if something were to ever happen, then you risk throwing your friendship out the window. This does not always happen, but if we are being honest, it's hard to stay friends after a breakup. But then again, it could be a perfect relationship, as well. I was skeptical when I started dating my best friend. Two years later, we are engaged. I am not trying to be negative and say that it wo not work- I am just saying that you have to think of what could happen down the road. Think about the girl who signed your cast- how does she make you feel compared to how your best friend makes you feel? Does she make you smile as much, laugh as much, get butterflies? Does she brighten your day when she sends you a text or simply smiles at you in the hall? Take into careful consideration how each girl makes you feel. Then go from there. The best thing you can do is be true to your heart. Listen to what your heart is telling you, and that is the direction you need to go in. Sure, it sounds corny saying that, but there's never been more truth in a statement. I know you will make the right choice for you, and I wish you and whichever lucky girl you choose all the happiness in the world. Enjoy and treasure her. :) Cheers2. How does a "potential relay" work in a window type air-conditioning unit?When the compressor stops, the condition inside the circuit is that there is a difference of pressure of approx. 70 psi between the high and low side pressure of the cycle, once the systems is equalized (in few minutes) the pressure will be the same in both sides, making easy to the compressor to start compressing the refrigerant and continue the cycle. I never heard of a potential relay. A relay itself is a switch, I can not really see how a switch can help to solve a lack of power. What the AC man may refer is to a Starting Capacitor, this gadget accumulates charge and it will released to the electrical circuit to boost the motor and overcome the torque that the compressor needs to start the cycle when the difference of pressure exists. As engineer (if you are) or engineer inclined person, doubt what the technicians tells you if that does not make sense and ask to collegiate engineers for a proper answer.3. My "House" Air Conditioning went out when my wife turned the air on?i know a lot about a lot, and i say call an HVAC tech, you can only make it worse by messing with it4. How much does it cost to get air conditioning recharged?The freon in your A/C system does not get "used up" so you have a leak somewhere. The repair shop is going to want to find and fix the leak first. To do the repair they will have to evacuate the system (remove the freon) with a special machine. Then they can replace the defective part. It might be as simple as a bad hose, or something worse like the compressor. Once the system is pressure-tight they will put freon back in the system. Be sure to use a shop you trust since the repairs can be expensive. If you are unsure, ask your family and friends for their recommendations. BTW, do not attempt to use one of those do-it-yourself cans you can buy at a parts store. You might just cause yourself more problems, overpressurized the system, or cause more damage.
Find Answers to the Hottest Questions About Air Conditioning
Do you want to know about Air Conditioning? Here are some frequently asked questions.1. What % of Americans don't have air conditioning?Air Conditioning ( Morality ) Your air conditioner is broke, a company charged you $85.00 to diagnose it so now you know the compressor is grounded and needs to be replaced. The fair price for coming out to diagnose "anything" should never be over $50.00, just so you know. So you call around to get pricing for changing out the bad compressor to get your AC running again only to find out the average company is charging $2500.00. You do some homework because you are a smart shopper and find out a whole new system is around $3000.00 (Goodman) so you wonder why this half of the AC is so expensive. * The truth is the compressor is the heart of an AC system. It pumps the blood of an AC system, the coolant (R22 or R410). So you find a company with the word "Integrity" in there name and think you got it made. You call to get a price on changing out the compressor and the sales person tells you it's also $69.00 to get it diagnosed again because they do not know that the other company that did it (that's also certified) knows what they are doing. ( I am an engineer for 25 years and have never seen anything simpler than an AC unit ) So by now you are truly upset because in this economy created by bush spending top dollar as if we were still under any other president makes no sense. This causes you to go do more homework. You quickly find out the compressor only costs $553.50, and it's exactly the right part number for your system. Being that you are not stupid, you do the math, total cost - price of compressor / hours it takes to change = hourly rate. ( $2569.00 - $553.50 ) / 5 = ( $403.10 ) per hour And most of the time is spent waiting for system to evacuate (drain). Does anyone else feel it's immoral to charge this much? just because "You Need It", so we can ream you good for it! A lawyer does not make $400 per hour! I have a bachelors degree in Computer Science and I have never made half of that an hour! The exam for AC systems is pathetic because it does not teach them morals! This is a crime in progress and we are all letting it happen! Some people just do not understand capitalism, they think it means screw anyone you can! Do not let big companies screw you! Find a good local contractor, after all small businesses care more about you and your business and are better for our economy as a whole. Good Luck NOTES: * The truth is, AC's are so unsophisticated of devices that paying $10,000.00 for a Rheem or Trane not only makes you wasteful in this economy but stupid as well.2. Is my landlord obligated to install Air Conditioning in NY?Your roommate is very wrong. NY law does not require a landlord to provide any type of cooling. Be grateful for what you have since many landlords in NY do not even allow their tenants any type of AC units. Those that do, require that the tenant pay for the unit themselves and charge extra for electric.3. Is air conditioning safe for newborn babies?Well, they had them on when my son was born4. Air flow on air conditioning filter?This Site Might Help You. RE: Air flow on air conditioning filter? I'm not going to ask a lot of stupid questions here, so overlook my lack of knowledge... I am changing the air filter upstairs, and I don't remember which direction it was pointing. The new filter has an arrow that says "Air flow". Well air naturally comes DOWN from the...5. 1996 Ford Probe Air Conditioning Question?The entire dash air flow system is vacuum controlled. If you have no vacuum to it at all, it will default to the defrost position. I would look under the hood and see if the main vacuum supply line is not broken or unplugged. It is normally a very small black plastic tube
Air Conditioning Is Having a Hard Time Cooling in the Hottest Parts of the Day? (long)?
If things are as you say then you are screwed. There is no practical thing you can do. If it were your building and you were willing to absorb the expense then the problem could be fixed. The AC units are undersized and the buildings are under insulated. Typical for apartment buildings that are thrown together as cheaply as possible. If you were able to move to a downstairs apartment you would be a little better off since you would not have a super heated attic space above you with only minimum or less insulation1. what are the leak detecting devices used in the automobile air-conditioning system?There are 2 common ways to test for A/C leaks. One is to use a device called a sniffer. It is an expensive and sensitive electronic device used for sensing the refridgerant. The most common way, however is with UV dye. The system gets a little dye added to it and then is checked over with a UV style light. If there is a leak, the dye glows2. Electrical/air conditioning problem? My electric bill last month was triple what it should be.?there may be internal components running still if the unit is receiving power, its not good to be turning it off at the main power all the time because there is an internal heater running which keeps the compressor from getting oil mixed in it, i would have someone come and inspect the unit for problems3. I have a small leak in the ceiling of the closet that houses my heating and air conditioning unit-?If you know where the leak is then just stop it, that's it. Leaks are impossible to find without looking so not able to help find because there are way to many ways water can leak around an air conditioner and outside tell us it rained heavy can only lead me to look around any roof penatrations such as the vent pipe if it is a gas fired unit. I would just keep an eye open because no matter what water if not controlled can cause lots of hidden problems so call a contractor to come luck if you can not find it or put the water sprinkler up on the roof and make it rain again and see if you can spot it. Good luck.4. does turning the fan on on your home air conditioning have any effect?When the fan is on, the AC is circulating the air, but not cooling it. And, this may be effective at circulating fresh air from the AC intake to the other rooms in the house. But, you might as well just open up a window, unless it's raining outside, there's a source of cool air right next to the intake vent (it's near an open door, for example), etc. Personally, I keep the fan on when I am home, including at night, because the the AC intake in my home is next to the entry foyer and I get a cool breeze coming in from the french doors in my entryway. So, it's usually the coolest part of the house when the afternoon breezes pick up. I also prefer to sleep with the windows shut, in case a dog barks or my cat is at the window whining to get in the house (happens a lot). Otherwise, it would be too warm and stuffy to sleep.5. Why is my Split Air Conditioning Unit's outdoor fan blows air towards the coils?Most condensers I've seen draw air from side and discharge it from the top. There are some that are the opposite depending on the manufacturer. Yours may be one of those brands, do not know, but that's what I would guess. Have to know the model number to say. Either way air is going over the coil to reject heat. Do not know if you have had any service on it lately, but the condenser may be dirty and need to be cleaned out with a garden hose, inside out, power off, top unscrewed and turned to one side carefully. If there are a lot of condensers all in one place there is less ambient air available to get to them because it's crowded.
How Does a Condenser in an Air Conditioning System Make the Coolant Cold? How Does It Work?
Actually, the cold comes from the expansion of the condensed liquid through a valve or orifice. The hot gas, under pressure from the compressor, is turned into a liquid in the condenser at approximately ambient temperature. Then the liquid expands through the orifice into a lower pressure zone in the cooling coil, that is when the temperature drops. It takes energy to do the expansion and it absorbs it from the interior of your vehicle. Then the now hot gas goes back to the suction of the com presser and the process repeats1. We need a new central air conditioning unit. Which are best?trane?the have a good waranty i thought2. When air conditioning your house, what do you do with the ceiling fans?I always have a fans going counter clockwise in the winter and clockwise in the summer.You might need another unit for this much space3. I haven't changed the filter on my air conditioning for 2 years?Probably they wo not charge her because she is probably not the only one who does not change filters regularly. FYI, she may not want to volunteer the information as to how long it has been unchanged for. It is important to change the filters so that you air stays cleaner.4. how can i cut down on my air conditioning unit electricity consumption?Set the temp at seventy six and use followers to flow the cool air interior the abode.remember westerly abode windows permit in too lots solar.A cave is often cooler than the coastline. So submit some sturdy curtains and save them closed.Use fluorescent bulbs in abode and save them of for the period of day to maintain cool.purely attempt holding the air shifting in abode.5. Is it possible to live comfortably (year round) in a house or apartment in Beverly Hills, CA that does not have air conditioning?You will want air conditioning. Although, some really well insulated houses you can get by without it. But, most places have air installed. Expensive houses6. How many greeners go without air conditioning, heating and hot water to stop Global Warming?Geo thermal heating and cooling . Wells & under ground lines below the frost line of the earth give us FREE 50 degree air conditioning . Heating 50 degree air is cheaper to maintain then heating colder airs . Geo cost about $15,000 more than a standard heat pump unit . .but pays for itself inside 10 yrs in savings on energy consumption . Hot water can easily be achieved thru solar paneling rising temperatures up to higher levels again making it cheaper to bring and maintain a higher temperature using less energy. Think about it , you here alot of bullshit tossed at these ideas . .. but it mainly set forth by energy companies. Its not made easy for the average joe guy to afford to " go green " , changing the world to be less reliant on major energy company would change the economic structure of things would not it. If we came up with free energy for everyone . ..somebody would want to control it. So do we have the best interest of our planet & people in mind ...or a greedy bank accounts ? Going green is pretty cool & pretty salty7. How do you keep an older house cool without air conditioning?window units and fans. my house was built 1906, and we had to put window units in , because there was no central air, which is better than central air i think.8. Can I still drive my car even though the air conditioning hose is broken?all and sundry already gave large solutions, particularly the single that sited the vet's information. i've got not had to handle it till some days in the past. We began our morning walk somewhat later than established. warm/humid days are unavoidable in my area, so i attempt to get out as quickly as i can interior the morning. The lab replaced into doing merely nice in direction of the top of the walk, so i presumed the blend replaced into ok besides, particularly thinking he has very short hair while in comparison with the lab. He would even taken a water injury a million/2 way by way of the walk. yet while we reached our highway, i spotted him beginning to stumble, and that i knew he replaced into overheating. adverse canines made it to the homestead the place I hosed him down, placed him interior, and had to pour water into my hand the place he could desire to drink. i replaced into heavily frightened, yet he replaced into nice returned in a short quantity of time.
