The vapor in the drum will have different proportions of refrigerants compared to liquid. Hence, the normal low-pressure side for R 134a needs to be less than 90 degrees. The compressor pressure ratio for R32 was about 5% higher than DR-5 for both compressors and it was measured that an increase of the amount of lubricating oil in circulation with the R32 refrigerant flow increased the compressor pressure ratio by as much as 31%. ,R410, R22 GAS Standing , Suction , Discharge pressure . Jun 8, 2020 - A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. The image above is of the Danfoss refrigerant slider app, and it shows that when suction pressure drops below 102 PSIG on an R410a system, the coil hits 32° and will start to freeze. For a single-component or azeotropic refrigerant, the operating pressure for the low side of a system can be found by cross referencing the desired coil temperature on the PT chart. The motor is cooled by the pumped liquid, and no fan-cooler is therefore used which make the sound level very low.
