ABSTRACT:
A refrigeration system incorporating a compressor sub-system which provides a source of higher pressure gaseous refrigerant to force liquid refrigerant into the receiver when condensor pressure is reduced sufficiently below normal to prevent it accomplishing the same purpose. When condensor pressure is insufficient to force liquid refrigerant from a pilot receiver tank to the receiver tank liquid accumulates in the pilot receiver tank to a level where it actuates a control valve, introducing said higher pressure gaseous refrigerant to said pilot tank and forcing liquid out. While condensor pressure is sufficient to the task, as is normally the case, the higher pressure gaseous refrigerant is received directly by the condensor.
