ABSTRACT:
A refrigeration system has an evaporator compartment containing a refrigeration evaporator and a refrigeration heat exchanger, a liquid line for conveying liquid refrigerant from a compressor through the heat exchanger to the evaporator, and a suction line for conveying vaporized refrigerant from the evaporator through the heat exchanger in heat exchange relationship with the liquid refrigerant flowing therethrough to a compressor. The refrigeration system also has a compartment to be cooled, and an air flow passage associated with the compartment for cooling thereof, the air flow passage passing through the evaporator compartment whereby the air flow passes over the liquid line and evaporator, the liquid line being thermally insulated from the air passing thereover. The refrigeration system may be used in a refrigerated merchandising display case.
