Are you being ironic? We face a future of climate chaos and ecosystem collapse, and you think you live in great times? Geothermal energy is energy taken from the Earth's core, it comes from heat generated during the original formation of the planet and the radioactive decay of materials, and is not green in any way. Just because it doesn't cause CO2 emmissions some shallow thinkers imagine it's part of the solution to global heating, it isn't, it's part of the problem, and while fossil fuels are being phased out geothermal is expanding because simple non thinkers imagine it's green. Just repeating low carbon is a mantra to reassure those scared of the consequences of climate change. Dream on.

yea but i think that the part at: 6:22 is misleading for people who just learn about this stuff from my personal logic/understanding the expansion valve just maintains the two different pressure zones and its not the thing that actually turns liquid into vapor I'm pretty sure that its the pressure drop doing that, and the pressure drop is caused by the compressor but this is just my logic and maybe im just nitpicking... anywa, the video is great

@martinlucas8274 2 жыл бұрын
Yep, it is fascinating. I just cannot get my head around how on earth it is more efficient than the water tank with a simple heating rod inside. Pushing the coolant (R134a) in your car costs you approx 10% of the total fuel consumption and some considerable power if you have petrol engine 1.1 litre. Even the most typical fridge-freezer - the compressor is using about 500W - to cool 20 deg celsius in maybe 0.5m3 I am not convinced this system is able to produce 70 celsius on even one small radiator and deliver hot water (52Celsius) to the taps. Have the thermodynamic laws changed recently?

Best explaination of the air to air system I have ever seen. I have 40 years in the HVAC system and I'm so tired of the "advertising" of the heat pump takes "heat" out of the ambient air outside and transfers it to heat in the house. When it's 10F degrees outside there is no heat there but when I try to explain the heat comes from the compression of the refridgerant out of the compressor I'm told I'm always wrong and even by some of the current crop of HVAC mechanics. I definitely subscribed and liked and will refer doubting Thomas's to your video!
@christophecamp2335 6 ай бұрын
When is 10°f, there's 10°out there. The phase change takes place anywhere north of -15°f, so it's definitely taking heat from the outside. You can test this by putting thermometers in front of and behind your outdoor unit.
@lisajohnson8566 6 ай бұрын
Respectfully Chris you're wrong. And what am I gonna do with 10 degrees in a house I'm trying to get to let's say 70? Take your time and figure out what is going on. You'll figure it out and don't just buy the hype of the heat pump. There is a reason modern thermostats let you select an OAT to not activate the heat pump and use Aux heat instead. Just figure out what you have and what you're trying to do. I promise you the light will go on and you'll respond I'm right. I've been in the business way too long my friend.
@michaelhuizenga2092 5 ай бұрын
@@lisajohnson8566Ask yourself how AC works, how can you make 90 air into 45 degree air that cools your house to 65 degrees on a hot summer day? It’s an energy transfer, and each system fluid has different levels of efficiency. This is why a harmful chemical like Freon is used. It can swing over 200 degrees between phases and pressures, whereas water cannot get cold without freezing, so your band is smaller. Efficiency will kill an H2O A/C.
@michaelhuizenga2092 5 ай бұрын
@@lisajohnson8566Additionally, Freon can go as cold as -25 to -55 degrees, which is colder than a cold day, so the needed heat transfer can still exist. The reason AC is much more efficient than heat pumps is the difference in temperatures. The hot Freon is much hotter than outside whereas the cold Freon is only a little colder than the outside cold. Think in terms of relativity and energy transfer more than temperature transfer, which if that was the case, a/c’s would not work and nor would heat pumps.

I apologize if this is mentioned somewhere in the video and I just missed it but I feel like its important to explain that the boiling point of the refrigerant mentioned was at atmospheric pressure. As pressure changes boiling point does too. 410a in an evaporator coil is usually at a boiling point between 36°f and 50°f this is why we get air in the 40-60 range leaving the coil.

I used the exact solenoid with a high flow rate as the fluid pushes down on the oversized valve land for sealing at static pressure. But mine is on an oil accumulator to pre-lube a gas V-8 engine. It is energized with the key on so during starting, it quickly floods the main oil gallery (High-Flow, 1/2" NPT, Viton Rubber Seal; New surplus at 1/10th the cost of Name Brand oil accumulator companies; with pressurized oil to the bearings. This would greatly extend the life of all "Stop-Start" engines in those vehicles. After being an ASE Master Tech since 78, I will argue a room of engineers under the table! 5,000hrs is the 150,000 mile equivalent that GM designs parts, materials and still make them to keep from paying CAFE a fine. It's a law passed by the Clinton administration. Great job on the video.

Everything is relative. Water boils at 212 degrees F at sea level pressure which is 14.7 psi. Have seen it boil in a vacuum at room temperature and it can boil at hundreds of degrees in a high pressure boiler. This is the basis of a refrigeration system. By manipulating temperatures and pressures you can force a refrigerant to either evaporate or condense which will either absorb or release heat. Basically using a refrigerant to transfer heat from one area and release it in another area.
