HEAT PUMP DEVICE

A heat pump apparatus (100) includes a use-side heat exchanger (14) that cause heat exchange to be performed between a heat medium (19) flowing from a heat-storage heat exchanger (12) and a heat usage medium (39), and a flow-passage switching device (13) that switches a flow passage for the heat med...

Beschreibung
Zusammenfassung:	A heat pump apparatus (100) includes a use-side heat exchanger (14) that cause heat exchange to be performed between a heat medium (19) flowing from a heat-storage heat exchanger (12) and a heat usage medium (39), and a flow-passage switching device (13) that switches a flow passage for the heat medium (19) to a first flow passage that circulates through a heat-reception-side heat exchanger (16) and the heat-storage heat exchanger (12) without extends through the use-side heat exchanger (14) or a second flow passage that circulates through the heat-reception-side heat exchanger (16) and the heat-storage heat exchanger (12) via the use-side heat exchanger (14). Even when the temperature of the heat storage medium (12) rises, heat received from a heat source can be stored in the heat storage medium (12) by a heat pump, while a decrease of the efficiency of the heat pump can be reduced.
