PURPOSE: A high efficiency hybrid type heat pump device is provided to produce high temperature water which is over 80°C and improve efficiency by heating hot water one more time to produce the high temperature water with a two-stage heat pump device. CONSTITUTION: A high efficiency hybrid type heat pump device includes a first step heat pump cycle (10), a second step heat pump cycle (20), a hot water tank (S1), and a cool water tank (S2). In the first step heat pump cycle, a refrigerant of a high temperature flows from a compressor (1) to a heat exchanger (2) for condensation and passes through a liquid receiver (3), a drier (4), and expansion side (5). After then, the refrigerant is cooled by passing through a plate type heat exchanger (5) for a thermal evaporator and returns to the compressor after passing through a plate type evaporator (8) and a regenerator. In the second step heat pump cycle, the refrigerant of the high temperature flows from a compressor (11) to a heat exchanger (12) for the condensation and passes through a liquid receiver (13), a drier (14), and an expansion side (15). The refrigerant is cooled by passing through a plate type heat exchanger (16) for the thermal evaporator and returns to the compressor by passing through a plate type evaporator (18) and a regenerator (19). The hot water tank is connected to the heat exchanger for the condensation so that hot water is circulated. The cool water tank is connected to the plate type heat exchanger so that cool water is circulated. |
