In reality, there will be line and valve pressure drops as the refrigerant travels through the evaporator and suction line. So, the technician must measure the pressure as close to the evaporator as possible to get a true evaporating pressure. On small systems where pressure drops are negligible, this pressure is … See more Listed below are field service terms or trade jargon often used to describe these pressures. Condensing pressure:High-side pressure, head pressure, discharge pressure. Evaporating pressure:Low-side pressure, suction … See more In reality, line and valve friction and the weight of the liquid itself cause pressure drops from the discharge of the compressor to the … See more Saturated condition:Saturation is usually talked about in reference to a temperature. The saturation temperature is the temperature that a fluid will phase change from liquid to vapor or vapor to liquid. Both the liquid and vapor at … See more Both the evaporator and condenser house liquid and vapor refrigerant simultaneously if the system is operating properly. So, refrigerant liquid and vapor can exist in either high- or low … See more WebCalculated pressure: R-22 High-Side pressure = (75 x 2) + 50 = 200 psig - you should take this as an upper limit.
