High refrigerant pressure -58
WebMost technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and … WebFeb 17, 2024 · High critical temperature and pressure: The critical temperature of the refrigerant should be as high as possible above the condensing temperature in order to have a greater heat transfer at a constant temperature. If this is not taken care of, then we will have excessive power consumption by the refrigeration system.

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
WebJul 23, 2024 · Here is a list of the pressure readings that are characteristic of an A/C compressor that is not blowing cold air into the cabin of your car: 250 PSI / 30 PSI = You have air somewhere in the system. 250 PSI / 50 PSI = The system is overcharged and the condenser is not cooling. Condenser may be blocked. WebCauses of High Compressor Discharge Pressure. Like any other problems related to the compressor or the air conditioning system for your car, there are causes that actually …
