  • Publication number: 20070068188
    Abstract: A refrigeration system for freezing fluid in a tray during a first operating mode and defrosting the ice during a second operating mode to facilitate the removal of the ice from the tray. In the first operating mode, refrigerant circulates through a circuit in a first direction and, in the second mode, the flow of refrigerant is reversed in a portion of the circuit. In the first operating mode, cool refrigerant exits an expansion device in the circuit and enters into the evaporator to freeze a fluid in the tray. In the second operating mode, a valve is operated to permit warm refrigerant exiting the compressor to enter into the evaporator to melt a portion of the ice reversing the flow of refrigerant therein. A second valve permits the reverse flow of refrigerant through the evaporator to return to the compressor inlet instead of passing through the expansion device and condenser.
