Great Video. I really appreciate your effort of sharing knowledge and help improving skills of others in the industry. This kind of simple and great explanations on UA-cam about refrigeration is very rare. Im watching your every video and huge fan of your cool teaching skills. Thank you very much for your service Sir🙏
Excellent video. This was very entertaining as well seeing you use the propane refrigerant for the demonstration. It’s talking me some time to catch up with all the excellent content!
R134A has lower thermal conductivity resulting in a lower cooling capacity approximately 60% in the higher temperature cooling in a house. It works well in medium temperature applications with low load and the variable compressor capacity of the automotive compressor.
Hello Ty! This might be a stupid question. But how is it possible for the refrigerant to stay in a saturated state in the tank, when the boiling point is at so low temperature? I mean, shouldn’t the refrigerant absorb heat from the tank and it all would transform in to vapor?
The boiling point is only low with a low pressure. For example 0psig it boils at a negative temperature. Once we squeeze it in a tank the pressure will be greater making the boiling point much higher. Keep watching the videos on order and you will see it.
Great question and the answer is no. You cannot have a flame or an explosion without oxygen. There is no oxygen inside a sealed system. Titan has an atmosphere made of methane, but there is no oxygen so it also cannot explode. www.rses.org/training/hydrocarbontrainingprogram.aspx If you have some oxygen it still cannot explode due to upper and lower explosion limits ua-cam.com/video/8jmX-TUQkx4/v-deo.html
Remember having a propane powered forklift tank that had a bad valve and it started spewing liquid propane all over. Had to get some hand cover to keep from getting too much contact with it. It's cold, all right.
The arguments love and hate for refregerants will go on forever. When you get to a system that has R600a you can simply say no, I refuse to work on it. You can also take the certification class, understand the operation and safety aspects and choose to accept it. The bigger problem is people putting it in systems not designed for it and people working on it without the tools knowledge and skills to do so and get hurt.
thanks for being one of the best HVAC influencers in the industry.

I keep hearing in all these HVAC videos about HFC Foretenay.
why r134a is not used in hvac, other than cars and home refrigerators?

If the start and stop running of compressor generates electrical arch inside of compressor will it cause R290 explosion?Thank you

What is that in microns
760,000 microns atmospheric pressure at sea level
Looks like a fly got a frostbite in the end of the vid)

My dad says R600a is a bastard gas.
