Consider the refrigerant R-410A: the pressure in the evaporator is 93.2 psia, according to the Table 8 (ASHRAE, 2013). The pressure value is used to find the saturation temperature.number for specific refrigerant). R-410A is a high-pressure refrigerant that requires the other components of the system to be rated for R-410A. For compressor lubrication, the refrigerant requires POE oil. Tranes ’ BCHC and BCVC 024-090 blower coil air hand ler products have also b een redesigned for use with the higher pressures of R-410A.The internal pressure relief valve is located between the high and low side of the compressor. It is designed to open when the discharge-to-suction pressure differential exceeds 550 to 625 psid (38-43 bar). When the valve opens, hot discharge gas is routed back into the area of the motor protector to cause a trip.Head pressure and High Side Pressure are the same, and pressure is in psig, not degrees F. You indicate the liquid line is 83F and the ambient air that cools the …Gonzo, if your evap was dirty you would have a low suction and low superheat. Not dirty evap let that go. High suction low head, with 100 lb suc and 100 degree ambient your head should be quite a bit higher. Really need the amp draw of comp and rated RLA but appears to be a compressor issue.
