WebDec 22, 2024 · When the compressor is powered, its job is to take low pressure, low-temperature refrigerant vapor from the suction line and compress it into a high-pressure, high-temperature refrigerant vapor into the discharge line. Compressors are designed to move vapor through a system, not liquid. WebApr 28, 2024 · The compressor operation will cut out once the pre-determined set point of the low-pressure switch, or LPS for short, has been reached. The LPS cut-out setting will be directly related to the application and/or refrigerant used. In reverse, on a call for cooling, the solenoid valve will open. aldi companies

Webswitch should trip. Reasons For Low Oil Pressure Low oil level (seen in the compressor oil sight glass) Check that the pressure in the crankcase is lower than the suction valve pressure by 0.1 bar (this pressure differential helps the oil to come back to the crankcase). Poor oil return to the compressor caused by low refrigerant pipeline ...
