The actual static pressure will depend on the ambient temperature. To ensure it is on the right level, refer to a static pressures table applicable for R134A refrigerant (N.B. not shown on this poster). The high side and low side pressure for refrigerants are measured in pounds per square inch (psi). For a car air conditioning system, R12 should be 170 to 210 psi on the high side and 30 to 40 psi on the low side. If the high side and low side pressures of your R12 are lower then it’s likely that it is undercharged; check for leaks and then ...Systems using R134a have slightly higher pressures than an R12 system. In addition, R134a systems use a different type of refrigerant oil which is specific to the type of compressor. R134a systems use a lower charge of refrigerant compared to R12 systems. There is a distinct temperature-pressure relationship for R-134a refrigerant.
