Other sources give the low side pressure range = 60 - 80 psig. Varies by indoor wet bulb temperature and outdoor ambient temperature, where higher heat loads increase the vapor line pressure.

R-22 Low-Side Typical Operating Pressure-Range = 58 - 85 psig.

R-22 Low-Side Turn-On Pressure = 50 psig (R22 at 30 deg F) is a typical pressure at which the HVACR compressor/condenser will turn-onġ00 psig (R 22 at 85 deg F) is a typical pressure at which the HVACR compressor will turn off.

R-22 Low-Side pressure when compressor is OFF = 30 psi at 90☏ ambient temperature, system OFF.

Prah, Frank, CMS, "Refrigerant 410A", Refrigeration Service Engineers Society, 1666 Rand Road, Des Plaines IL 60016 USA, Tel: 84, retrieved 9, original source: Low pressure refrigerant switches on Carrier HVACR typically open at 50 psi and close at 100 psi. On a properly-charged and working air conditioning system using R-22 refrigerant R22 Refrigerant Pressure Rules of Thumb Typical Off, Low, High side R22 Pressures & Temperatures

These psig readings for R-22 are what you'd expect the pressure of the gas to be in an enclosed container at the temperature given and at steady state.īoth older R-22 and R-134 operate at lower pressures than R-410A.Typical high side pressure, may vary by equipment.Typical low pressure or suction side, may vary by equipment and metering controls - these are "gauge pressure readings" or "psig".This chart is using outdoor ambient temperature.R22 and other common refrigerants is an odorless, colorless gas that will be liquid at sufficiently low temperature and/or high pressure.R2 status: no longer in active use, replaced with R458A.R22 gas cylinder identification: light green.R22 density: 3.66 g/cm 3, in gas form - this is a colorless gas.R22 boiling point: -40.8 degree Celsius at atmospheric pressure (sea level or 1 ATM).R22 alternative names: CHClF 2 Chlorodifluoromethane, Difluoromonochloromethane, generic term: hydrochlorofluorocarbon (HCFC).R22 temperature/pressure relationship: see the table above.Bar = atmospheres where 1 Bar = 14.5 psig or normal pressure at sea level.R-22 Refrigerant Temperature vs Pressure Data

R 404A and later R407c may replace R22 in some applications.īelow this table of example refrigerant operating pressures for R-22, we provide links to complete refrigerant pressure/temperature charts as PDF files that you can download free. R22 was phased out in 2010 and is no longer widely available. R-22 Refrigerant DataĬFCs, ChloroFluoroCarbons - first generation refrigerants like R22 (1950s & later) were widely used in refrigerators and air conditioners. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.
