Do you have a heating and cooling system that takes R …Jun 25, 2016 · The liquid pressure should be 385-395 and the suction pressure should be about 138 but will probably be a few psi lower since it's so cool in the space. The sub-cool should be 11 deg. F +/- 1.5 deg. F. There's also the simple fact that higher pressure = higher temperature on the basic physics side. If the suction pressure is low, the density of the refrigerant is also lower (again, basic physics), which means that the compression ratio will be higher to get it up to the head pressure, AND lower-density refrigerant won't be able to cool the compressor …In this HVAC Training Video, I show How to Add R-410A into a Running Air Conditioner that is Very Low on Refrigerant. I Show the Step by Step Procedure for C...The pressure generated on the output side of a gas compressor in a refrigeration or air conditioning system is known as discharge pressure (also known as high side pressure or head pressure).
