That’s not even mentioning the hoses, …Low-Pressure Suction Side. The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume.R-22 Refrigerant Fact & Information Sheet. R-22 refrigerant, or Freon, was and still is one of the most popular refrigerants used in the world. R-22 is an HCFC refrigerant and can harm the Ozone layer. It was originally invented by a partnership with General Motors and the DuPont company all the way back in the 1930’s.

R410a Vs. …Although the market prices change constantly, you can expect to pay $4-$6 dollars per pound for R410A. R22 can cost up to $35 per pound, though about $20 per pound, as this shot shows. Note the number of pounds and the cost. 5lbs of R22 is $169 or about $34 per pound. 10lbs of R22 is $219, or almost $22 per pound.At 318.5 PSI, the saturated temperature is 100°F. If you measure 118 PSI on the low-pressure side of the system, then you know that the saturated temperature of the refrigerant flowing through the middle of the evaporator coil is at 40°F. This is a useful number when combined with the temperature of the tubing near the pressure port. Thermodynamic properties of R22, like vapor volume, enthalpy and entropy at pressures from 30 to 260 psia.
