Jun 03, 2004· Let's take another look at an R-134a system. Low-side pressure at the compressor is 20 psig or 23 degrees F. (See Table 1.) The compressor inlet temperature equals 50 degrees. The total superheat calculation is as follows: Degrees compressor in temperature (50 degrees) minus saturation temperature (23 degrees) equals total superheat (27 degrees).

Aug 27, 2018· R-134a vs R12 Temp Pressure Chart. R-134A has a slightly lower pressure at evaporator temperatures (30-40 degrees), but R-134a also has a much higher pressure at condenser temperatures (120-150 degrees). NOTE: For best heat transfer, condenser temperatures should be 30-40 degrees hotter than the ambient air temperature entering the condenser.
