ABSTRACT:
A compression type refrigeration system having a compressor, a condenser and an evaporator positioned remotely from the condenser, a liquid feed line connecting the condenser outlet with the evaporator inlet, said feed line having a length, and an expansion device located in the liquid feed line and positioned remotely from the evaporator. Where multiple evaporators are employed a novel distributing device is employed to divide the main refrigerant stream flowing in the liquid feed line between the expansion device and the evaporators into sub-streams which flow to each of the multiple evaporators. A hot gas defrost is provided which is designed to avoid condensation of refrigerant within the defrosting evaporator.
