Geothermal cooling is a better alternative. Considering the earth at around 15 feet deep is constantly at 20c, this method will not contribute to heating the atmosphere. This is also good for countries that are cold because again, no matter where in the world, at a certain depth, the temperature is only around 20c.

Your you tube video is outdated about air conditioners: 1) Modern Aircons use newer coolants and very soon may even use Co2 coolants as well. These coolants have only 1-4x times warming capacity of CO2 and not thousands of times as you are saying and through proper disposal they will not contribute anything to global warming as these coolants are buried deep inside earth. 2) The total heat released by aircon does create heat islands in cities but its impact in raising temperature is minuscule compared total atmospheric heat. 3) The only way in which aircons contribute to global warming is by consuming more electricity which uses more energy burning more fossil fuels but with greater use of renewable energy , even these could become redundant.

Isn't using a reversible heat pump more efficient than just burning fuels? So we pump the heat out when we want it cooler inside, and we pump the heat in when we want it warmer inside. I've also started to want an all-in-one unit that uses the waste heat from the AC to help the water heater.

@CorwynGC 5 лет назад

Reversible heat pumps are more efficient AT THE SITE, whether it is more efficient, or more green, depends on how you make your electricity. Solar plus a heat pump is a cheap, green, and efficient system. But still not as good as using more insulation, night flushing the heat, and other such passive measures.

Shad Sterling My uncle’s “old” house, which they got built in the 1990s, has (or at least had) large “heat catchers” that warmed water for both heating the house and regular hot water. To facilitate this it had a gigantic hot water tank - 4000 litres if I remember correctly.

@PhilmannDark 5 лет назад

A lot of poor people in Asia buy AC units now. They are buying the cheapest product available, they just dump it somewhere when it breaks because returning it for recycling would cost money they don't have and the installation is usually, say, "not meeting professional standards".

Most Air Conditioning systems can reverse the cooling process and heat up your home by cooling the outside. Wich needs only ~10% of the energy than heating up the inside with coal, oil or gas.

The localized warming might be true (you unfortunately didn't tell us which of your references that number cam from for easy confirmation and further details) but it can't contribute global warming because there is no change to the total heat energy in the system (Except for the waste heat from running the AC with electricity of course but again, that's true for running any electronic device and is not specific to AC). Putting it the way it was presented in the video is misleading IMO. 3.

The thermal energy dumped outside your house *does not* change the overall thermal output of your city (unless of course you only place thermometers outside, and disingenuously claim that the average temperature has risen!) *You can completely reverse the effect of a heat pump* (be it your fridge, or AC) *just by leaving it turned off for a few hours.*

The hot air released from air conditioners as exhaust doesn't contribute to climate change. The cold air inside your home will eventually be released back to the outdoors, re-balancing the differential. Otherwise, you'd be looking at free energy, which isn't a thing.

@otaku3OBSESSION Год назад

... no? The usage of coals, fuel, and electricity takes one medium of energy (being chemical energy), and converts it to another form of energy as heat. Heat energy is constantly lost by our planet through the atmosphere, and simultaneously we gain both light and heat energy from the sun. It means the Earth is not a closed system, energy flows in and out at variable rates. One of those variable is greenhouse gases, as is their namesake, they prevent heat loss from leaving the Earth. By converting fuel into the energy used to pump out hot air, you further disrupt the planet's heat cycle. Cold air doesn't get "released" from your homes, the heat energy of objects transfers into the cold air. You assume that the heat pumped out can be let back into the house, when fluid dynamics shows hot air rises, and it is more difficult to transfer energy into insulated homes, against the direction of gravity, than it is to just release into the upper atmosphere.

If we start a global energy project, perhaps organized by the UN, to supply Thorium fueled nuclear power to the world, including the developing world, we could essentially solve these problem for good. Waste is managable, the energy is completely clean and molten salt reactors are very reliable and safe. Ideally we could fund this project with a form of extra-national tax that is adjusted based on GDP per capita. This way the whole world gets clean, cheap energy that is fair to everyone and doesn't affect economic competition between countries.

@Triffgits 5 лет назад

This video is full of mistakes, and immediately sneaks in some "givens" that aren't necessarily true at all. Where do you think the HEAT inside your house which AC removes COMES from? Most of it is going to be heat taken from the atmosphere that you're trying to keep out in the first place. The rest will be waste heat which is going to make it out of the building one way or another, mostly through radiation and conduction. What makes you think that heat would stay magically isolated in the absence of an air conditioner? What about places where grid energy is provided by hydro electric, solar, wind, or nuclear energy? What about places where it's mandatory to dispose of refrigerant responsibly and has processes and facilities in place to deal with it? It seems like you immediately misinform your audience with a handful of half truths and then go on to implicate those in a total argument for the entire concept of a heat pump.

@@pkmntrainermann4476 You are very unaware of how much cooling is VITAL to survival my new friend... No worries. I will hook you right up mate. I suggest spending a few summers in white sands new mexico or Kuwait if you would like a proper lesson in dealing with arid climates. Thankfully I now live far away from deserts these days. I have to now move, stack, and split *6 tons* of wood each year, by hand mind you to heat my home as that is the primary heat source available to me. Doing things like correcting the insolation, windows, and adding soap stone to my wood stove went a very long way to making sure that I don't have to use even more wood during the 6 months of winter I have to deal with. I can guarantee that in my town alone, at least 50% of the population has not done what I have done. Worse, there are a ton of oil fired heaters around here. So yes, addressing heating will be FAR more helpful to dealing with this issue since we only really need the AC for 3 out of 12 months. Why do we *NEED* it? Because some of us have family that literally will die in high heat that would be merely uncomfortable to others.

@@derptothemaxclearly Cooling is needed for survival but the amount of cooling that is needed is very less and most people who use AC are using it much more than necessary. An AC set at 27 degrees Celsius can ensure comfortable health whereas when people use AC at 24 degrees Celsius for example, it is nothing but addiction. In most places using an evaporative cooler (in dry places) or a dehumidifier (in humid places) can work very well enough and is much more sustainable than using ACs.

Heat is energy, all air-conditioning does is transfer energy from one place to another. Air-conditioning doesn't create new energy. Therefore, it's impossible for the running of air-conditioning alone to cause any kind of global warming. It's the other factors such as electricity generation to run the air-conditioning that's the real issue. If you run a air-conditioner strictly off solar panels it has no affect on the environment because you are not creating anything that wasn't already there. You are just simply transferring energy from one place to another.

Another cool tech is "space cooling" where we literally radiate heat into space. This works by emitting infra red frequencies for which the atmosphere (=air, water vapor, clouds and dust) is transparent. Infra red telescopes use the same trick to look deep into space.
