Ambient temperature - 70°F; Refrigerated space temperature - 30°F; Compressor volts - 230v; Compressor amps - Low; Low-side (evaporator) pressure - 1.8 psig (minus 10°F) High-side (condensing) pressure - 95 psig (85°F) Calculated Values: Condenser split - 15°F; Condenser subcooling - 15°F;R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level. On the low-side R22 pressure at 85 degrees displays 60 psi, whereas on the high-side R22 pressure at 85 degrees shows 250 psi. For servicing of the compressors, the right way is to follow the service manual.Usually with our R290 refrigerant, charging can be done by bringing the low side pressure up to a point of about 10 pounds below the outside air temperature. At 80 Degrees F. bring the pressure up to approximately 70 lbs. This works quite well up to about 85 degrees. Above that, we prefer the pressure to be 15 lbs below the outside temperature.The high side pressure for R134a should be around 150 to 175 psi, while the low side pressure should range from 18 to 30 psi at lower ambient temperatures and 31 to 35 psi at higher ambient temperatures. These pressure specifications are crucial for safe and effective operation of HVAC systems.
