When operated at a 35 degC ambient temperature, the suction pressure of an Air-Conditioner with R410A refrigerants ranges from 115 to 125 Psig. At these operating conditions, the discharge pressure is around 400 Psig. R-410A operates at 50 to 70% higher pressures than the R-22.On to what’s changed. Ok, so obviously the refrigerant has changed but the big and noticeable difference here is the pressure change. 410A is anywhere from fifty to sixty percent higher pressure than R-22. So, while the basic design and operating procedures of 410A remain the same as R-22 extra caution should be paid to the pressure of 410A.Higher operating pressures: R410a operates at significantly higher pressures than R22. Air conditioning and refrigeration systems designed for R22 need modifications or upgrades to use R410a. This is because R410a has higher pressures than R22. This can result in increased costs for equipment replacement or retrofitting.Operating an air conditioner for extended periods of time in low temperatures outdoors lowers the suction pressure to a velocity where the oil will not return to the compressor and will run dry. Also, under low ambient conditions “indoors” does not provide sufficient load to change refrigerant from a liquid to a 100% vapor.R-410A when operating at normal operating pressures and temperatures has higher pressures there fore the old R-22 refrigerant systems needed to be buffed up some to handle the higher pressures.
