ABSTRACT:
A cooling device having a refrigeration chamber (1) and a freezer chamber (3), a refrigeration plant having an evaporator (15) and condenser (18), a compressor (16) and air flow passageways (5, 8, 11) for conducting air flow across the evaporator and through the refrigerator and freezer. Capillaries of different size (19, 20) control the flow of refrigerant from the condenser to the evaporator to control the temperature of the evaporator. A pressure device (36) produces the air flow through the passageways to the refrigerator and freezer. Motorized valves (30, 31) are operated by temperature sensors within the refrigerator and freezer to control the flow of air therethrough. A variable temperature compartment (4) may be provided and connected to the airflow passages, with a flow control valve (32) for maintaining a temperature therein set by the user.
