PURPOSE: A hot water supplying device of a heat pump is provided to obtain the outflow water of the high temperature by heating the water which heat-exchanges first and second refrigerants in the first and second refrigerant/ water heat exchangers respectively through about two times. CONSTITUTION: A hot water supplying device of a heat pump comprises first and second cycles(10, 30), a refrigerant heat exchanger(20), first and second refrigerant/ water heat exchangers(40, 50, 52). The first and second cycles use first and second refrigerants respectively. The refrigerant heat exchanger is located between the first and second cycles. The refrigerant heat exchanger heat-exchanges the first and second refrigerants. The first refrigerant/ water heat exchanger firstly heat-exchanges the first refrigerant and water. The second refrigerant/ water heat exchanger secondly heat-exchanges the second refrigerant and water. |
