Abstract: A heat pump water heater and systems and methods for its control. The systems are configured to heat water within a water storage tank of a heat pump water heater wherein a controller within the system is operatively connected to a plurality of heat sources including at least one electric heating element and a heat pump and sensors in order to selectively energize one of the plurality of heat sources. The controller is configure to process data representative of the temperature of water within the tank near the top of the water storage tank, and rate of water flowing out of the water storage tank, in order to automatically selectively energize the heat sources. The selection of heat sources by the controller is determined by a mode of operation selected by the user and the data processed by the controller in view of the selected mode of operation.

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.
