Abstract:
1. A closed refrigeration circuit comprising: a compressor having an inlet and an outlet; a condenser having an inlet coupled to the compressor outlet and an outlet; a receiver having an inlet in a top region in fluid communication with the condenser outlet and an outlet in a bottom region located at a lower elevation than the receiver inlet; an evaporator having an inlet in fluid communication with the receiver outlet and an outlet; a suction line having an inlet coupled to the evaporator outlet and an outlet coupled to the compressor inlet; a first capillary throttling element oriented between condenser and receiver; and a second capillary throttling element oriented between receiver and evaporator; wherein the suction line is orientated adjacent to and in thermal contact with the receiver so that gaseous refrigerant in the suction line pass from adjacent the receiver bottom towards receiver top, while the refrigerant in the receiver flows from the receiver top towards the receiver bottom.
