Abstract: A refrigeration system has a primary refrigeration circuit with an evaporator, a network driver, a condenser, and an expansion valve. These components are connected in series by a primary refrigerant line. The system also has a secondary refrigeration circuit which includes the evaporator, the condenser, and a bypass valve conncted in series by a secondary refrigerant line. The secondary refrigerant line is in fluid communication with the primary refrigerant line and has a network driver bypass line bridging an inlet and an outlet of the network driver. The network driver bypass line incorporates the bypass valve. A controller selectively de-activates the primary refrigeration circuit by de-activating the network driver and activates the secondary refrigeration circuit by opening the bypass valve.

Abstract: A refrigerator (10) or a freezer comprises a primary refrigeration system (11) which is augmented with a passive secondary refrigeration loop (15) having a condenser (30) in thermal contact with a primary fluid line (12) at the location between a primary compressor (16) and a primary condenser (18) and preferably placed outside a building so that the passive secondary refrigeration loop (15) provides cooling to the primary refrigeration system (11) when the outside temperature is sufficiently low The condenser (30) of the passive secondary refrigeration loop (15) is positioned above the points where the primary fluid line (12) connects with mlet (32) and outlet (34) lines of the secondary loop condenser (30)
