The low pressure side is the larger of the 2 pipes coming out of or going into the outside compressor unit. The high pressure side is the small diameter line. The low pressure side carries R22 gas while the high pressure line carries R22 in a liquid state. R22 changes from a liquid to a gas in the evaporator coils of the air handler. R-410A systems operate at higher pressures than standard R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. Ensure service equipment is rated for R-410A.! WARNING Refrigeration systems contain refrigerant under pressure. Extreme caution should be observed when handling refrigerants. Wear safety glasses … What should my normal operating pressures on 410a systems be? R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there’s absolutely ‘no’ set point pressure for 410a, r22, or anything else. Educate yourself on whats going on in the heat transfer process. The following properties are included: density, pressure, internal energy, enthalpy, entropy, heat capacity at constant pressure, heat capacity at constant volume, speed of sound, and the Joule-Thomson coefficient, in both single-phase states and along the liquid-vapour saturation boundary.
