R22 suction and discharge pressure chart
Using R-22 in an air conditioning application, gauge suction pressure is at 70 PSI and gauge discharge pressure is at 250 PSI. First you need to convert these gauge pressures to PSIA . That means that 15 pounds is added to each gauge pressure. You might recall that our atmospheric pressure is equal to 14.7 pounds pressure at sea level but our ...R-22 refrigerant is the major refrigerant, or… it was. R-22 was invented by a partnership with General Motors and DuPont back in the 1930’s. In the 1950’s the use of R-22 exploded and for nearly sixty years it was THE refrigerant to be used in home, office, and commercial air conditioning. Along with air conditioning it was also used in ...Suction pressure tells us several things. The first thing it tells us is what the boiling temperature of the refrigerant in the evaporator is. If the suction pressure is below 32° saturation temperature, the evaporator coil will eventually freeze. As a general rule, the higher the temperature of the air passing over the evaporator, the higher ...

If, for example, the discharge temperature were 210˚ with a 150 psi head pressure, a 10 psi suction, and a 50˚ outdoor temperature, this would show an extreme undercharge. Subcool and superheat can still be checked in heat mode, the problem is since there are rarely any set guidelines, it is difficult to tell when the charge is set correctly by …(Kitco News) - Gold and silver prices are moderately lower in midday U.S. trading Monday.

These line sizing charts are based on a suction pressure drop equivalent to a 2°F change in saturation pressure and liquid line pressure drop of 5 psi. For R-404A Low Temperature 1 psi; for R-404A and ... This is particularly important on discharge hot gas lines for strength, and suction lines for reduced pressure drop. Vibration Isolation and Piping …R-404A History. R-404A rose to prominence in the late 1990’s with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.Mar 18, 2019 · R-600a Applications. Isobutane is being seen more and more across the world. This holds especially true as various countries begin to phase out the ever common HFC refrigerants such as R-404A and R-134a.
