WebNov 13, 2024 · When the motor remains off for a certain period, pressure in the whole system equalizes the refrigerant low-pressure number so that it can stay close to the outdoor or the room temperature. It is observed that R22 pressure at 85 degrees settles at 143.7 psi, while for the other system, like R410, the pressure at 85 degrees is 235.9 psi. WebApr 8, 2024 · If a system is running a head pressure of 235 psig and a suction pressure of 10 psig, the compression ratio would be: (235 + 15) psia ÷ (10 + 15) psia = 250 psia ÷ 25 psia = 10 to 1 or 10:1. A compression ratio of 10:1 simply means that the high-side pressure is 10 times greater than the low-side pressure.
