Abstract
An appliance includes a compression stage, a condensation stage, and an evaporation stage. The evaporation stage includes a first evaporator for a first refrigerated enclosure and a second evaporator for a second refrigerated enclosure. A first valve in a condensation stage bypass line is openable to allow a supply of refrigerant to bypass the condensation stage during a defrost mode, where a condensation stage bypass line is positioned between an output of the compression stage and the second evaporator. A second valve is positioned in a line from the second evaporator to the input to the compression stage and is closeable to block a supply of refrigerant from the second evaporator to the compression stage during the defrost mode. An additional line positioned between the second evaporator and the first evaporator carries the supply of refrigerant from the second evaporator to the first evaporator in the defrost mode.
