Problems solved by technology

[0003] However, in this air conditioner, the hot water generating device can only be used to generate hot water without other functions, and its size needs to meet the maximum load required for supplying hot water, and the air conditioner water heat exchanger can only be used to Produce air-conditioning water without other uses, and its size needs to meet the maximum load required by the air-conditioning
When it only needs to be used for heating or cooling of indoor air but does not need to supply hot water, the hot water generating device cannot be used. The water heat exchanger cannot be utilized
In this way, the load of each heat exchanger in the air conditioner needs to be relatively large and its utilization efficiency is low.

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.
