Abstract:
1. A cooling system for a refrigerator that includes a food compartment, the cooling system comprising: a refrigerant; a condenser assembly configured to provide heat energy exchange with said refrigerant; a dryer in communication with said condenser assembly; a hot gas loop configured to channel said refrigerant from said condenser assembly to said dryer; at least one detector configured to detect at least one of a temperature within the food compartment and an ambient temperature; and a switching device operatively coupled between said condenser assembly and said hot gas loop, said switching device providing a first fluid path bypassing said hot gas loop to said dryer and a second fluid path through said hot gas loop to said dryer, said switching device configured to channel said refrigerant during operation of said cooling system along one of said first fluid path and said second fluid path based on at least one of the temperature within the food compartment and the ambient temperature detected by said at least one detector.
