You would need a different system to keep it that temperature. 22 degrees is in between medium and low temperature in the industry. Comfort cooling systems use in houses are considered high- temperature.

The coils should be around 30 degrees cooler so you would need a refrigerant that boils at a very low temperature since the vapor is what absorbs the heat. You would need a system that takes like R-404A.

Pressure is controlled by the metering device.

Yes, you're right. In the illustration, it shows the return air @ 70F which is correct. But it also shows the evap temp @ 50F when it should be 40F. The outside condenser temp is normally 125F. So he does'nt explain superheat and subcooling temps.

Amazing video!

how the hell do you control the pressure?

[jefferson17399]

Air blowing across the pipes. No, its the cooling coils.

[jefferson17399]

Your video has to do with A/C System. Do you have any training? The word gas should be vapor.

Concerning pressure - High pressure causes boiling. Why are you stating low pressure? Water boils at 212F at 14.696 pressure and 29.92 mercury.

Decreasing pressure does not = boiling. The spray bottle cylinder cools because the liquid will begin to vaporize and absorb heat from the surrounding liquid. Temperature and pressure determine boiling point.

This video has a lot of errors

hi there I'm wondering to cool down a 7x7x5 meters room from 32 to 22 what is the temperature at the cooling coil would be?

excellent information
