WebRefrigerant R32 had 17 to 30°C (30 to 55°F) higher discharge temperature than that of R410A. DR-5 had slightly increased discharge temperature by 3 to 5°C (5.4 to 9°F). For R1234yf and DR-4, the compressor discharge temperatures were lower by about 11 to 30°C (20 to 55°F) and 5 to 9°C (9 to 16.2°F), respectively, in comparison to that ... Web13 nov. 2024 · Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi ( R22 pressure at 85 degrees ). R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level.

Web8 jul. 2024 · In refrigeration, the DTD is much lower than in air conditioning. There are several reasons for this, but one big reason is the desire to maintain relatively high relative humidity levels in refrigeration to keep from drying out and damaging the product. WebIn existing systems mid-size refrigeration applications, between 2 to 40 kW, we recommend R448A, R449A or R452A. The same applies for new installations at medium temperatures, including R134a. We can see A2L-R454A, R455C and R1234yf emerging for new systems.
