Abstract
A refrigeration system includes in a closed loop connection a compressor for compressing a refrigerant, a desuperheater for cooling the hot compressor discharge gas via the injection of liquid refrigerant, and a condenser for condensing the compressed, desuperheated refrigerant into a liquid refrigerant. The liquid refrigerant is injected into the compressed refrigerant by utilizing a liquid column for supplying pressure to the liquid refrigerant for injecting liquid refrigerant into the compressed refrigerant without using a mechanical pump. Another method of injecting the liquid refrigerant into the compressed refrigerant is to use a venturi pump at the injection point to supply the liquid refrigerant for injection into the compressed refrigerant. The desuperheater causes the temperature of the hot refrigerant vapor leaving the compressor to be reduced from a superheated condition to temperature closer to its condensing temperature prior to its entry to the condenser. This results in lower condensing temperatures with consequent increases in capacity and system efficiency.
