Abstract:
1. A refrigeration system having in closed loop relationship a pressurizer, a condenser, an expansion device and an evaporator, with the evaporator having an inlet header, an outlet header and a plurality of channels fluidly interconnecting the inlet header to the outlet header, comprising: a superheating heat exchanger fluidly interconnected within the system and having a high pressure side and a low pressure side being thermally connected, and with said high pressure side fluidly interconnecting the condenser to the inlet header by way of the expansion device and said low pressure side fluidly interconnecting said outlet header to said pressurizer wherein said outlet header includes a liquid outlet and a vapor outlet, and means for separating refrigerant liquid from refrigerant vapor; said liquid outlet is fluidly connected to said superheating heat exchanger; said vapor outlet is fluidly connected to the pressurizer; said superheating heat exchanger is so sized as to cause complete evaporation to a vapor of the liquid refrigerant flowing from said liquid outlet; and said superheating heat exchanger is further so sized as to cause superheating of the refrigerant vapor.
