Abstract
A refrigerator apparatus is provided having a cabinet with a freezer compartment and a fresh food compartment. The compartments define two passageways allowing air circulation therebetween. A refrigerator system is included having a compressor, a condenser, an expansion valve, an evaporator situated in the freezer compartment. The refrigerator system elements are connected in series in a closed loop, in a refrigerant flow relationship. A first fan is situated in the freezer compartment for providing air flow over the evaporator. A second fan is situated in one of the two passageways for providing air circulation between the two compartments. A first thermostatic controller situated in the freezer compartment by causing the compressor and the first fan to operate. A second thermostatic controller situated in the fresh food compartment for maintaining a desired temperature in the fresh food compartment by causing operation of the second fan circulating air between the compartments thereby cooling the fresh food compartment.
