Does Olivier Van Aken's Quote Imply That Plants Can Feel Pain Or Vice Versa?

It is important to consider the context of this quote from Dr. Van Aken. It was presented in a university press release, and press releases tend to use language that is non-scientific or even sensationalist.The actual scientific study being featured was Mitochondrial and Chloroplast Stress Responses Are Modulated in Distinct Touch and Chemical Inhibition Phases by Dr. Van Aken et. al, published July 2016.

The published text of the study does not use words like "aware" or "pain" because that's not what was being studied at all. Here's what Dr. Van Aken actually wrote:Together, our results show that several regulatory systems can independently affect energy organelle function in response to stress, providing different means to exert operational control. Notice that there areAn air conditioning unit also has a regulatory system as a means to exert operational control over the air temperature of an enclosed space. The presence of a regulatory system does not imply consciousness or the ability to feel pain.Don't get fooled by sensationalist press releases. Dr. Van Aken has not claimed that plants feel pain.

Olivier Van Aken, a plant biologist at the University of Western Australia, is often quoted (like here) as saying: While plants dont appear to complain when we pinch a flower, step on them, or just brush by them while going for a walk, they are fully aware of this contact and are rapidly responding to our treatment of them,

The use of the term "fully aware" implies the presence of consciousness in plants, and though the quote doesn't say that plants feel pain, articles often use the quote to imply that they do.

Is there a rebuttal to Van Aken's insistence of plants being "fully aware" of being crushed?

Has Van Aken stated publicly somewhere that plants don't feel pain?

Needless to mention, replacement of any component inside the refrigerant path will need the refrigerant to be removed, and then recharged after the job is over. Ask any Uber driver the importance of an air conditioning system and they will tell you it can be the swinger between a good and a bad rating. Again, the higher rating is always more efficient, so aim as high as you can. If you want to stay comfortable all year-round while cutting on energy costs, Window ACs with heat are the best option for you. And what we find are that the reasons for your A/C blowing mildly cool or warm air range from simple to complex, and from cheap to expensive. They can be caused by normal wear and tear, or actual damage or malfunctioning parts.Needless to mention, replacement of any component inside the refrigerant path will need the refrigerant to be removed, and then recharged after the job is over. In the old times there were issues with tubing in the AC systems in cars since they never had them there in the first place. It was mainly done with tubing which was bent and brazed into place with zero considerations for serviceability (providing break-off points to remove components or sections). This made it very difficult to keep the lines running the refrigerant free from leaks due to stress / strain / vibrations / chaffing / corrosion.Cooling and Air Conditioning for a Camper Van - Build A Green RVSome features that will make your camper van more comfortable on warm days: • Insulate the van well - if you can include a reflective layer with an airspace in the insulation stackup, this helps with radiant heat transfer. • Use reflective shades in the windows to insulate and (more important) to avoid solar heat gain. • Park in the shade - shade makes a very large difference in what the inside temperature will climb to. Cuts heat gain about in half.Central Air Conditioning Cost in 2021 - Buyer's GuideWhile size of rooms relates to BTU's, there's also overall size of your home, its shape, how it is oriented in relation to the sun, shade, and prevailing winds.

Initially, I only spray and left the mist to dry up but later I found out that when you mist your face, the water evaporates, which can dry your skin so it's really better to pat my skin dry with a tissue paper after misting. And it's true that doing so makes my skin feels a lot more hydrated. So this is really great on when used during air travel as airplane oxygen and air conditioning typically leave our skin more parched.How Air Conditioning Made Us Lazy - The Five Best Ideas of the Day: July 5, 2016The Five Best Ideas of the Day: July 5, 2016What air conditioning tells us about innovation - and Ernie Smith in TediumScientists are building a cyborg-insect to sniff out Beth Miller at WUSTLnews at Washington University in St. LouisCan we re-wire convicts to stay out of jail?by Jack Bush at NPRHow to reinvent high school with neuroscience and human-centered Patrick Cook-Deegan in the Stanford Social Innovation ReviewWhat if the terrorists are already here?by Uri Friedman in the AtlanticSign up to get the Five Best Ideas of the Day in your inbox every dayHow was the air conditioning inventedAir conditioning. is the cooling of indoor air for thermal comfort. In a broader sense, the term can refer to any form of cooling, heating, ventilation, or disinfection that modifies the condition of air. An air conditioner (often referred to as AC or air con.) is an appliance, system, or machine designed to stabilise the air temperature and humidity within an area (used for cooling as well as heating depending on the air properties at a given time), typically using a refrigeration cycle but sometimes using evaporation, commonly for comfort cooling in buildings and motor vehicles.CMR, CMP, and Direct-Burial Cable- What's the Difference?The second type of cable defined by the NFPA is CMP or Plenum cables. Plenum cable is rated for the "plenum spaces" in buildings, which are simply the parts of the building that facilitate air circulation in heating and air conditioning systems. Plenum cable is covered in fire-retardant and low-smoke plastics, in the hopes of slowing the spread of fire and smoke to the living spaces in the building. CMP cable meets all the requirements for CMR cable and can therefore be used in risers, but CMR cable can not be installed in the plenum spaces.
My Central Air Conditioning Unit Freezes Where the Filter Is Located and Turns Off...?
My Central Air Conditioning Unit Freezes Where the Filter Is Located and Turns Off...?
My central Air conditioning unit freezes where the filter is located and turns off...?Sounds to me like you have an airflow problem, or a low refrigerant level. Check to see that the filter is clean, and the coils are not dirty, and limiting the amount of air that can flow through it. However, if it has been neglected for some time, you may need to have the coils washed in an acid bath. If it is a low refrigerant level, you will need a certified a/c man to add some r-22 to the unit. Good luck.— — — — — —My central air conditioning does not turn off turn off for a long time.?It WILL probably run almost all the time trying to keep those temperatures. Air conditioners lose efficiency the hotter it gets while at the same time the demand on them increases because they use the ambient (outside) to cool the condenser exhausting the heat. And if it is your electric bill that makes you question it be aware that your electric rates were recently some of the highest in the nation as a result of the same deregulation that let your Enron screw over all of us on the West Coast with their fraud and price manipulation. So please excuse me for taking pleasure in the irony of the pay back. It is your turn now.— — — — — —How Long Does It Take to Install Central Air Conditioning Unit | SummitOne of the first questions we are asked when people are considering a central air system is "How long will it take to install a central air conditioning unit?" And while the answer is always a firm "it depends", there are several factors we need to consider. In the interest of answering this question to everybody's satisfaction, we will go over some of the factors that might impact the installation time. Things that will affect the time it takes to install central AC in your Denver home There are three main factors that will impact the length of time it takes to install your central air system: • The size of your home will affect the time it takes to install central air If your home is 10,000 square feet, it will likely take more time to install your AC system than if your home was 2,000 square feet. Larger homes often require more than one unit to cool the entire house efficiently, so logically it will take more time. • If you are installing a new central air system or replacing an old one If you are changing out an older AC unit for a newer or similar one, the job will generally take one day, or eight hours - as long as the other components, like the ductwork, remain the same. This is what we call a changeout. On the other hand, if you are installing a brand-new system, your technicians will likely be installing everything-the ductwork, the thermostats, and so on. If your old unit was installed in the 1960s, for instance, it's likely that the ductwork is asbestos, which will require a very careful removal to ensure your safety. If we are replacing an old system, we will first have to do the changeout and then install new ductwork. This is the most extensive aspect of the job, and depending on the size of your house, could take up to three days or more. • The type, size, and location of your central air unit will impact the installation time Split units, packaged units, condensing units - depending on the type of central air you are installing and where it needs to go, it may take some extra time. For instance, if the location of your unit is in tight quarters, on the roof of a condo, or in the back corner of your basement, it will be significantly more complex than if it were to be in a readily accessible part of your garage. The harder we have to work, the more time it's going to take. So, as you can see, there are many variables at play here. On the plus side, if it's a simple changeout or a straightforward installation in an average-sized home, you will likely be sitting in cool comfort within 24 hours. The larger the house, the more issues we have to deal with, the longer it will take. On this end of the scale, this could mean anywhere from two to four days. If you would like to speak to a technician about how long it would take to install central air in your Metro Denver home, call today for a quote.

Automobiles are equipped with various systems that we take for granted until they fail, and those systems affect gas mileage. Two systems that drastically increase fuel consumption are the electrical charging and air-conditioning systems. When the weather is hot and we turn on the air conditioner to keep cool, the electrical charging system is also operating the blowers that move the inside air and cool the engine's radiator. These loads on the engine outweigh the air density effects on the engine and those of the car moving through the air— — — — — —How Air Conditioning Affects Your Eyes | air conditioning units provide us with a comfortable environment, they can also dry out our eyes. Air-con units reduce the level of humidity in the air, causing our eyes to feel uncomfortable. Our eyes need a certain level of moisture from the air around us to produce tears. By drying out the environment, air-con units interrupt the tear film production. Our tear film carries out a variety of tasks to make sure our eyes function correctly. This includes delivering oxygen to the cornea and providing the front surface of our eyes with lubrication to keep them moist and the structure smooth. The lacrimal glands produce a fluid that is replaced about 15 times per minute. It is a mixture of oils and mucous which spreads across our eyes when we blink to protect them from drying out. If you are in an environment where you are particularly close to the conditioned air flow, your tear film can evaporate before it has time to renew. This can lead to symptoms of eye dryness. There are several measures that you can take to combat how air conditioning affects your eyes: • None Maintain your fluid intake throughout the day. • None Try to keep the temperature at a constant and avoid turning the air con unit on and off. • None Avoid sitting directly under the flow of air coming from the unit. • None If you have an air conditioning system in your home, ensure that it is well maintained so that bacteria do not develop and spread through the air flow. • None rich in fish, fruits and green veggies to keep your eyes healthy. For quick and instant relief, lubricating eye drops could be a great choice for replacing lost moisture. For example, the blink intensive eye drops have been created to rehydrate and relieve eye dryness symptoms. blink intensive tears eye drops are available in a multi-dose formulation and in handy sized preservative-free vials; perfect for keeping in your bag or drawer at work.

Brand Concentration Continues to Rise, and the Pattern of the Top Three Brands of Air Conditioning I
Brand Concentration Continues to Rise, and the Pattern of the Top Three Brands of Air Conditioning I
On February 21, 2019, the National Information Center released the 2018 air conditioning market analysis report. This report is the 11th consecutive year. According to the report data, in 2018, the market sales volume and sales volume of key cities decreased by 10.6% and 7.6% respectively, and the annual proportion showed a trend of low at both ends and high in the middle. Under the influence of various factors, the overall industry presents three trends: further product optimization, intensified brand competition and significantly innovation driven.The mainstream air conditioning brands led by Gree, Midea, Haier and oaks have played a key role in promoting product optimization, innovation and upgrading of the whole industry.Brand concentration continues to rise, and the pattern of the top three brands is difficult to breakIn 2018, the market competition has shifted from output and price to multi-dimensional competition such as marketing channels, financial strength, human resources, upstream and downstream linkages, technology R & D, international market and modern management methods. With the upgrading of consumer demand and the gradual enhancement of brand awareness, consumers are more inclined to trusted brands when buying, which is directly reflected in the brand concentration of the air conditioning industry, which once again shows a high expansion advantage.The top ten brands composed of Gree, Midea, Haier, oaks, TCL, Hisense, Zhigao, Kelon, Changhong and Galanz have a total market share of 95.17% in 2018. Gree, Midea and Haier, the top 3 brands in the industry, achieved contrarian growth, and the total market share increased from 68.88% in 2017 to 71.17%, an increase of nearly 3 percentage points year-on-year. The first group brand, composed of Gree, Midea, Haier and oaks, has significantly strengthened its market control ability, gradually widened its market share gap with the second group brand, continued to strengthen its brand concentration, and squeezed other brands more obviously.According to the analysis of insiders, the high brand concentration indicates that the market control ability of relevant brands has been significantly improved, and the main impact is the improvement of the market threshold. Those small and medium-sized brands that do not have strong overall competitive strength may eventually be eliminated by the market, and quality is still an important factor to win market share.Demand upgrading drives product optimization, and the share of intelligent air conditioner increases against the trendAt present, China's economy has changed from the stage of high-speed growth to the stage of high-quality development. There have been major changes in the economic structure, residents' consumption has changed to improve the quality of life, and product innovation has entered an active period. This active innovation is manifested in the optimization and upgrading of products in the air conditioning industry. At the same time, consumers' awareness of air conditioning products has reached a historic high: they are no longer satisfied with basic functions such as simple refrigeration and heating, and put forward higher requirements for more and more demand elements such as health, environmental protection, comfort, silence and home integration.In 2018, the proportion of intelligent air conditioning in the overall air conditioning sales and sales reached 24.98% and 31.17% respectively, an increase of 6 and 10 percentage points respectively over 2017. Among them, Haier air conditioner ranks first in the industry with 36.16% sales and 37.73% sales. From the analysis of market situation, the competition of intelligent air conditioning brands is still concentrated in Haier, Gree and Midea. Although the market share of other intelligent air conditioning brands has increased, it has not affected the market pattern in which the three brands are the main competitors. Intelligent and high-end innovative products have become an important means to help improve the technical level of the air conditioning industry.Healthy self-cleaning has become a new premium point, and the average price of the overall market has risenGrasping consumer demand and outputting high-value solutions has become the key to the competition of air conditioning enterprises in 2018. In addition to the intelligence of air conditioning, self-cleaning air conditioning products that emphasize health and comfort have also become a new strong premium point. In 2018, self-cleaning air conditioners will be popularized rapidly and become a new trend in the industry.From the monitoring data of key cities, in 2018, the domestic self-cleaning air conditioning market remained high and concentrated, and the sales volume of top5 brand accounted for 97.16%. Among them, Haier's sales of self-cleaning air conditioners accounted for 36.66% and 37.73%, ranking first in the self-cleaning air conditioner market in 2018.Compared with 2017, the middle and high-end consumption structure of air conditioning in 2018 showed an obvious change trend. According to the data of the National Information Center, the average price of the overall market in 2018 was 3734 yuan / set, an increase of 122 yuan / set compared with 3612 yuan / set in 2017, a year-on-year increase of nearly 3.3 percentage points. The average price of the overall air conditioning market rose for the third consecutive year. The further transformation of products to high-end shows that the innovation and development power of the whole industry is at a relatively healthy level.Under the background of the slowdown or even downward growth of the industry, differentiated product innovation has become the key to enhance the competitiveness of air conditioning enterprises. Gree, Midea and Haier have made systematic efforts from various aspects such as technological innovation, product upgrading and intelligent manufacturing, accurately grasped the direction of consumption upgrading, and further led the air conditioning market. The National Information Center believes that at present, the brand competition in the domestic air conditioning industry is still reflected in the high concentration of brand concentration, and the Matthew effect of the strong will continue.
Window Air Conditioner Cleaning
Window Air Conditioner Cleaning
googletag.display("div-ad-articleLeader");Many homeowners depend on their A.Cs to keep the temperatures tolerable during the hot summer months. A.Cs are more of a requirement rather tahn a modern convenience for many, especially those who live in hot and humid environments. Cleaning your AC helps to keep it in tip top shape and a reliable. Window ACs are installed in windows or through pre-cut holes in walls. Installation through a window is a temporary, seasonal installation and through a wall is a permanent installation. Window air conditioning units are generally used in houses or apartments that do not have duct work for a central air conditioning unit. A window AC units has the same components as a central air unit in a more compact space. Cleaning your window AC is very important because an AC with a clogged, dirty filter or dirty components is much less efficient than a clean one. This is especially true if you have pets and pet fur or dander clogging the filter. Clogged and dirty filters can lead to an early demise for your AC and increased cooling costs because your AC unit will have to work much harder. Fortunately cleaning a window air conditioning unit is easy and straightforward.Cleaning the Drip HoleBefore installing through a window, make sure the drip-hole is not clogged or plugged. The drip hole is a small hole that allows the condensation to drip outside.If the drip hole is plugged the condensation can drip into your walls.Check the drip hole every 2 to 3 weeks during the season.If the AC is installed through a wall, always check the dip hole before turning it on and every 2 to 3 weeks.AC CleaningVacuum all exposed areas of your A.C every week.Clean the air conditioning filter every 2 to 4 weeks throughout the season. Clean the filter more often if you have pets or live in a particularly dirty or dusty area like a large city or in close proximity to a busy highway or construction site.Remove the filter from the window unit and wash with warm water and a mild detergent. Rinse very well to remove any soap residue. Allow the filter to dry completely before putting it back in place.Remember to unplug the A.C before removing the filter and cleaning. If the unit is not unplugged you can receive a nasty shock and/or damage the AC.If the filter is disposable, replace it with a new filter. Window A.C filters can be purchased at hardware stores, home improvement stores, online and directly from the manufacturer.While the filter is out of the A.C, vacuum the interior of the AC unit to remove built up dust and dirt.If any of the metal fins are bent or crushed use a fin comb to carefully straighten them out. A fin comb is a tool made expressly to straight out fins on ACs and heating units.Keep the outside of the air conditioning unit free of dirt, debris, bird's nests and bee hives. function articleAdMiddleLoad()if (typeof jQuery != "undefined") var lastPosition = 0;var minimumDistanceBetweenAds = 1200;var minimumDistanceFromBottom = 300;var adsToPlace = 20;for(var i = 1; i 0// element is after last placed ad&& !$(this).hasClass("articleAdMiddle")// element is not an ad&& ($(this).position().top - lastPosition > minimumDistanceBetweenAds // enough space between ads&& $(".articleText").height() - $(this).position().top > minimumDistanceFromBottom// enough space from the bottom of the article|| $(this).prev().hasClass("articleSlideshow") // previous element is a slideshow))$(this).before($("#articleAdMiddle" i));googletag.display("div-ad-articleMiddle" i);lastPosition = $(this).position().top;spotFound = true;return false;);// If no spot can be found, stop the loop and remove any remaining banner slots.if(!spotFound)for(var j = i; j
Central Air Conditioning Unit Will Not Run Below 73 Degrees Without Coils Freezing Up and Loud Hummi
Central Air Conditioning Unit Will Not Run Below 73 Degrees Without Coils Freezing Up and Loud Hummi
The lower the relative humidity the faster the evaporator coils freeze in the A/C unit. In arid regions and in industrial applications they run water over the conndensor coils and possible the evaporator coils to prevent icing up. All you can do is run it at a higher temperature setting and let it rest longer between run times so the coils can thaw out. Good Luck!1. what is the step by step procedure for recharging a domestic split air conditioning unit?HVAC is not a do it your self job i go to to many calls and fix what a home owner tried to fix that would have been an easy fix then it turns very expensive2. How much does it cost to add a second air conditioning unit to a home?It's impossible for anyone on the Internet to give you a cost. We do not know where you live, what the construction of your home is like, how well your home is insulated, what the walls and windows are like, etc., plus what size system you presently have. All these things (and more) will factor into what you will need. My guess is you could be looking at anywhere from $3,500 and up. Do you have enough room in your attic for another air handler and duct work, and another return air? The thing is, you can not just take ducts from the existing system and use them for the new system for many technical reasons that I wo not go into. Your best bet, rather than asking on the Internet, is to have an HVAC contractor come to your home and work up an estimate. In fact, have at least three contractors give you bids. Most will do this at no cost, but you may have to call around as it's the busy time of the year. Just curious, but have you had anyone look over your present system to see if there's anything that can be done to improve the situation? Cooling and heating two-story homes with one system can be a challenge, though3. can a drop in voltage from a corroded main circuit breaker cause damage to a 220 volt air conditioning unit?Yes. Your AC unit is designed to run at 220 volts. The lower the voltage the higher the current to produce the same power. The windings in the motors will overheat as a result and ultimately burn out the motors in the compressor and the fan If the electric motors do not have a thermal cutout.4. If my apartment has an air conditioning unit, would it be enough to cool the whole apartment?My experience has been it's only useful in the room it's in. That's why it's called a "room air conditioner". And even then - it did not work all that well for the room.5. I WAS TOLD I NEED TO REPLACE MY COMPRESSOR UNIT ON MY WHOLE HOUSE AIR CONDITIONING UNIT BY YEARS END?r-22 phaseout is 1/01/10he almost right it depends if your evap coil is rated for 410 the metering device can be changed if the coil is compatible for 410 but yes r-22 condensers are running very low and time is running out call manufactor of your evap coil and ask can it be changed to 410 if not id change condenser old bug eyes an idiot6. Is it more expensive to run an air conditioning unit than to run two box fans?The answer is yes. The air conditioner is more expensive as there is a fan motor running and the compressor. The compressor is the big current user. The air conditioner will keep your room much cooler. I bet your parents have an air conditioner in their room. My parents did. Dave7. I want to see if there is a way to disable an air conditioning unit at my house?There's no easy way to do it that is user friendly and easy to fix. I would suggest giving her an ultimatum: 1. Stop doing it. 2. Move out. 3. Pay 1/2 of the electric bill and you two can split the other 1/2.8. How do I prevent mold from growing on my wall air conditioning unit?Clean it with bleach every few days
How Air Conditioning Can Exacerbate Allergy Symptoms | Dr. Shukla
How Air Conditioning Can Exacerbate Allergy Symptoms | Dr. ShuklaWhen you are allergic to airborne allergens and contaminants, anything that affects the air quality can exacerbate your condition. Air conditioning, for example, can significantly increase the amount and severity of allergy symptoms for many reasons. Here is a list of how air conditioning can exacerbate allergy symptoms and how to combat the effects. With central and standalone air conditioning units, the airflow in a dwelling is restricted. And while this means that new allergens are not being introduced into the air from open windows, this also means that any allergens or impurities in the air are trapped and are continually being recirculated through the building. Therefore, anyone who is allergic to the specific allergens or contaminants that are trapped will be continually affected by them. Additionally, air conditioning can provide an ideal environment for other allergens to grow and thrive. In the case of central air conditioning, cooler air passes through ducts located in the attic and walls. When these blasts of cool air mingle with much warmer air, it produces condensation; which is an ideal environment for mold to grow. Mold is one of the main irritants that plague allergy sufferers. With a standalone or window air conditioning unit, you have to worry about being more susceptible to respiratory illnesses, as well. A window unit works by drawing the heat and humidity from the room to lower the ambient temperature. This dehumidifier effect actually can dry out the mucous membrane of your nose and make it more susceptible to airborne viruses and impurities. In this way, air conditioning cannot just exacerbate allergy symptoms, but asthma attacks, as well. During the fall and winter months, if a window air conditioning unit is not adequately covered it also creates the perfect environment for mold spores to grow in and around the unit, therefore contaminating the air quality inside the home. On both standalone and central air conditioning units, if the filters are not changed regularly, then the contaminants that were filtered out can be reintroduced into the air. How to Reduce the Effects of Air Conditioning on Allergies One significant way to reduce the effects of central air conditioning on allergy symptoms is to have your air ducts professionally cleaned on a regular basis. At least once a year, it's best to have a qualified HVAC specialist inspect your air ducts for leaks and properly clean them to prevent impurities from re-contaminating your air. It's important for you to clean and change your air filters on a regular basis, as well. For most air condition filters, it's good enough to simply just rinse them with regular tap water to clean them. However, always double-check the manual that came with the system to ensure you are cleaning the filters in the correct manner. For allergy sufferers, High-Efficiency Particulate Air (HEPA) filters are the most efficient choice for removing contaminants and impurities from the air. They are also disposable so you can simply just remove and replace them instead of cleaning, if you prefer. Even if these measures do not alleviate your allergy symptoms, you can also look at investing in an air purifier. Remember that many other appliances can affect the air quality in your home and can require regular maintenance in order to keep allergic reactions at bay. Air purifiers, humidifiers, and dehumidifiers are all examples of appliances that can relieve allergy symptoms if properly used and maintained. However, when these appliances are not properly maintained, they can significantly increase allergy symptoms. Therefore, it is important to appropriately change and clean filters for air purifiers regularly so that they do not redistribute the impurities throughout the rooms the same way that air conditioners do. And just like air conditioners, air purifiers work best when HEPA filters are used. It is also important to regularly clean humidifiers and dehumidifiers as they provide an ideal environment for mold to grow if they are not maintained. Now that you know the different ways air conditioning can exacerbate allergy symptoms, be sure to practice proper maintenance to keep the air quality in your home safe. Mayank Shukla today.— — — — — —What is the best way to get rid of mold in an attic?It needs to be very dry for it to stop growing. It should have light and air, but it is a toxic thing, and even if you stop it's progression, the residue is still there, contaminating the air quality of the house. The attic could perhaps be sealed from the rest of the house better, improving air quality somewhat, but the residue will still be there.
Can I Power a/C and Furanance From Two Different Services?
Usually, air conditioning units are simple things. They have In this case, the furnace and the A/C unit are connected only by the freon hoses and the 24V thermostat line. There is no mains AC power connection. The furnace does not care where the A/C unit gets its power, it could come off a diesel engine and it wouldn't care. The 24V control power is generated by the furnace using a transformer, from its mains power supply. However the 24V is its own totally separate service; it doesn't care which service the A/C unit is on. So... I think your problem is somewhere else. I think that electricity isn't getting to the A/C unit, you didn't turn a breaker on, you disconnected the thermostat wire, etc. If your air conditioning unit is not like I describe here, then that may be a problem. There are some modern units that do some more complicated things. Fine then, so what? The fact is, a furnace unit draws fairly little electricity - only a few hundred watts for the fan to blow air around. So the furnace adds fairly little load to the panel and it doesn't really need to be on a separate service in your case. Oh wait, your heat is electric? (Or heat pump with aux heat). Yes, electric heat is a very big load indeed. But like the air conditioner is supposed to be, the huge heating elements are contactor controlled, and are electrically very simple, and could be powered from a different serviceI combined a duplex (with separate electric service) into a single unit. It still has two electric services and they're small.I learned from another question that I should not try to merge two different main services from the power company into one panel.So I tried to reallocate my AC to the other power panel for the other service. The AC won't turn on after that. Do I need to move the furnace to the same power panel? Any other possible reason the furnace won't turn on? It used to work just fine, before I moved the AC power line to a different power panel.·OTHER ANSWER:I combined a duplex (with separate electric service) into a single unit.

"global Warming," More Air Conditioning, and More Energy
There are countless ways in which the world will require more energy, lots more energy. Unfortunately, most of these continually go brushed aside by rich Westerners that already have all the energy that they want conveniently at their fingertips. But, outside our bubble, over 6.2 billion humans still live in undeveloped nations, assuring that global energy demand has really just begun.In our IPCC-reported warming world, one key area that will require massive amounts of more energy is: naturally enough.....cooling. The world now faces surging demand for air conditioning, refrigeration, etc. that is mounting so fast that it could obliterate emission targets and make the incremental requirement for more coal, oil, and natural gas far greater than some Western leaders want you to know.Generally using more electricity for air conditioning than all other countries combined, the U.S. has no room to complain. Our residential air conditioning needs alone devour 6-8% of the country’s electricity, or about 290 terawatt hours per year, more electricity than is used in all sectors in Mexico, with 125 million people.To illustrate, home central air conditioning systems can gobble up over 3,000 kWh per year, or more electricity per capita than is used by more than half of the world. Hot states like Florida and Texas have 98% of homes using air conditioning. The air conditioners in our cars alone use some 655,000 barrels of gasoline per day, more gasoline than Germany and Italy use in total combined. And again, definitely not a panacea even for air conditioning, energy efficiency benefits go vastly overstated.Remember “The Jevons Paradox" and “The Rebound Effect?" No, of course not, but they're both critical yet conveniently ignored concepts that explain how greater efficiency often allows people to actually use more, not less, energy.For example, since 1980, room air conditioning units have increased their efficiency by about 60% (i.e., require 60% less electricity). But, played out in real life, efficiency frequently doesn't equate to absolute demand reductions.More efficiency in cooling has just allowed allowed us to use more air conditioners, with families often having 2, 3, or even 4 rooms cooled by individual units. (I'm suddenly reminded of Back to the Future's"Oh honey, he's teasing you, nobody has two television sets." Well now, everybody does!). In fact, electricity demand per air conditioned American household has increased over 40% since 1990 alone.U.S. Home Electricity Needs for Air Conditioning are Immense Source: JTCAs it turns out, it's not just Americans that want air conditioners to make cars, homes, and offices more comfortable, while also making cities more livable. And the rest of the world deserves the same luxuries that we have much more so than many Western leaders apparently realize.And it all equates to...more energy, lots more energy - no matter what.Propelled by a warming world and a quickly growing middle class, the developing countries, which often sit in hotter regions, are experiencing a surge in air conditioning. Global electricity demand for air conditioning is projected to rise nearly 35 times by 2100 as incomes increase and urbanization swells at its current staggering rate of 75 million people a year, an environmental and developmental positive:Indeed, talk about “Global Warming:" the world's cities are now adding the metropolitan areas of Tokyo, Mexico City, and New York City combined…every year. And we already know: 1) air conditioners make the surrounding outside air even hotter, part of the "The Heat Island Effect" (have you been to Manhattan in August?) and 2) urbanites devour nearly 4 times more energy than their rural counterpartsdue tomore money and better access.According to the EPA, cities can be a whopping22°F hotter at night than surrounding areas.Andone analysis projects that even with "successively more efficient generations of equipment," global electricity consumption for home cooling will still increase nearly 8-fold by 2050, not much better than the 10-fold gain that would occur without efficiency improvements.Soaring China, of course, leads the pack. Looking to become a consumer-based economy, China has been selling 50-75 million home air conditioners per year, in a country where coal is 77 % of electricity. In fast follower India, where coal is 70% of electricity, air conditioning already accounts for nearly 45% power use in Mumbai, 23 million people sweltering in perhaps the world’s largest hottest city, still consuming just 7-10% of the electricity that New Yorkers do. Dr. Michael Sivak, a leading expert at the University of Michigan, has found that the potential cooling demand in Mumbai is nearly 25% of the demand for the entire U.S.The young and scorching Middle East will be a major player too, which will greatly impact the global oil market. For example, about 55% of Saudi Arabia’s peak summer power consumption goes to air conditioning, eating up over 1 billion barrels of oil a year.Demonstrating the hugely inconvenient truth for some that the world has just started to consume electricity for air conditioning, Dr. Sivak finds that:Unsurprisingly, it’s rising personal incomes that will continue to lead to more air conditioners and more electricity use in the poor countries.From 2015-2030, the real GDP per capita in the developing nations will nearly double to $8,650, which will still be just 1/6 of what Americans earn today. So, our complaints about energy usage should and will continue to fall on deaf ears.My apologies to His Holiness, but air conditioning is hardly a “harmful habit,” but plain and simply a matter of public health, particularly in a warming world that is overwhelmingly poor. Even in the well-equipped and rich United States, heat waves kill hundreds of people per year, with the elderly particularly vulnerable.How bad could it get in the undeveloped world? The Indian heat wave in May killed at least 2,500 people, while theheat wave in Pakistan in June killed over 1,200.The Explosion in Mega-Cities Mean More Air Conditioning (over 10 million inhabitants) Source: JTC; EPAAnd the Undeveloped Nations are Much Hotter (mega-cities as the example) Source: Holiday Weather; Sivak; JTCIndeed, cooling is a vital part of the 21st Century that will no longer be confined to the developed world, nor just air conditioning. Many medicines, for instance, require constant refrigeration, andelectricity deprivation creates a breakdown in the crucial vaccine ‘‘Cold Chain" that quietly kills the very same poor people that too many Americans seek to restrict energy options for. Not to mention the criticality of cooling for chemicals, steel, and plastics manufacturing, along with the Internet's technologies and data centers.Even the noble goal of enormous poverty reduction means more energy demand via cooling. For example, China has lifted 650 million people out of poverty since 1990, and back then, just 10% of Chinese families owned a refrigerator, but today it’s close to 95%.And rest assured Mr. Gore there’s so much more to come: for example, 750 million Indians have no refrigeration. These refrigerators can devour 500 kWh, or more electricity than hundreds of millions of Indians use, which would certainly boom the country's current 600 million tonnes of coal used to generate power.This all explains why the "divestment" and "stranded asset" movements against coal, oil, and natural gas are not only dangerously hypocritical, but their success is surely an impossibility. They are, in fact, a creation of the Western mind (an Archie Bunkerish "pigment of your imagination"), where energy supply based on fossil fuels is highly available and reliable.Everywhere you turn, our most fundamental energy reality is becoming increasingly obvious: energy demand and the need for moreenergy supply is going up, up, up. Cooling is just another example of how renewables will have to run much faster just to stand still. The increasing needs of humanity arethat great.With the undeveloped world adding 2.4 billion humans by 2050, the world is already greatly energy deprived. Over 950 million Sub-Saharan Africans, for instance, use less electricity than 4.9 million Alabamans.No sir.....irreplaceable and supplying 85% of all energy, producing coal, oil, and natural gas and generating electricity are very good businesses to be in. Their futures are very bright, regardless of what you keep hearing from those in natural gas-powered offices in San Francisco.
