WebNov 2, 2003 · A typical R-22 system operating normally with a head pressure of 260 psig at a 120 degree condensing temperature and a low side pressure of 76 psig at a 45 degree evaporator saturation temperature will find the equivalent pressures in a R-410A system to be much higher. WebThe pressure-temperature (PT) chart is a valuable tool that service technicians use to check proper system operation. PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature; to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator and to …
