What should the high and low side pressures be for 410a? What is the difference between an economic good and a free good? Pound for pound R134a is a more efficient refrigerant than R12, however it runs at higher pressures in some aspects and therefore requires more effective condensing. It absorbs and releases the heat better than R-22, making your compressor run cooler so that it does not overheat. Source(s): https://shrinkurl.im/a8Zb1. On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI. Whether R134a performs as well as R12 in any given a/c system depends upon system components and the amount of R134a used. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges. Also Know, what should my Pressures be for r22? For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressure of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F. The performance of the system is identical to with R22 refrigerant. The real issue will be the oil. What cars have the most expensive catalytic converters?
