Abstract
A heat pump includes a compressor, a metering device, a first heat exchanger, a second heat exchanger, a first fan, a second fan, and a refrigerant circuit between the first heat exchanger and the second heat exchanger. A thermal storage device coupled to the refrigerant circuit is configured to store thermal energy when the refrigerant fluid is above a threshold temperature and discharge thermal energy when the refrigerant fluid is below the threshold temperature. The heat pump is operated in a heating mode in which heat is transferred from the refrigerant fluid at the first heat exchanger and the temperature of the refrigerant fluid at the thermal storage device is above the threshold temperature, and a defrost mode in which heat is transferred to the refrigerant fluid at the first heat exchanger and the temperature of the refrigerant fluid at the thermal storage device is below the threshold temperature.
