Abstract

A heat pump unit comprises a refrigerating fluid stream, a hot water stream, an air conditioning water stream and a switch controllable channel. The invention is characterized in that the refrigerating fluid stream comprises a compressor, a hot water heat exchanger, an air conditioning water heat exchanger, an outdoor heat exchanger, a four-way valve and a decompressor; the hot water stream comprises a hot water heat exchanger, a hot water stream recycle pump, a water tank for storing hot water and a first valve connected between the hot water heat exchanger and the water tank; the air conditioning water stream comprises an air conditioning water heat exchanger, an air conditioning water recycle pump, an indoor heat exchanger for transmitting heat energy between the air conditioning water and the indoor air, and a second valve connected between the air conditioning water heat exchanger and an indoor heat exchanger; the switch controllable channel is connected between the hot water stream and the air conditioning water stream. The heat pump of the invention can simultaneously utilize both the hot water heat exchanger and the air conditioning water heat exchanger to produce water for the air conditioner, which increases the ratio of the performance of system to cost.
