Low suction pressure high head pressure
The normal operating pressure for R-404A in a freezer at a temperature of 70 degrees Fahrenheit and a suction temperature of 30 degrees Fahrenheit would be around 9.6 psi. The low pressure should be 18-20 psi while the high pressure should be around 200 psi. However, this can vary depending on the specific conditions of the freezer and …The Net Positive Suction Head (NPSH) margin is a crucial factor that is commonly overlooked while selecting a pump. ... Pumps work by creating a pressure differential between the inlet and the outlet—the high pressure at the inlet causes fluid to flow towards the low pressure at the outlet. As the fluid flows through the pump, it …

It was 90+ out today and I dumped r-22 into the system and no matter what I did I could not get the suction line to sweat and the superheat never dropped below about 20 degrees. my head pressure was around 285 ...Typical low pressure or suction side pressure for R410A is about 120 psi, varying by ambient temperature, here assuming 75°F, may vary by equipment and metering controls. 3. Typical high side pressure for R410A is < 600 psi at an ambient outdoor temperature of 95 °F, may vary by equipment. 4.In the cooling mode this will result in low suction pressure and low discharge pressure. Sub cooling would be extra high. However, heatpumps can't always be charged accurately using sub cooling alone. Usually "a stuck check valve" can be freed-up by using a strong magnet.
