Heat pump system, heat pump unit using the same, and method for controlling multiple functional modes thereof
A heat pump system, a controlling method thereof, and a heat pump unit using the heat pump system. The heat pump system includes a compressor, a first heat exchanger, a second heat exchanger, a heat-recovery-type heat exchanger, a multi-way valve, a throttling element, and a mode-switching flow path, which has both air conditioning and water heating functions. By switching the multi-way valve and powering on/off electromagnetic valves in the heat pump system, the controlling method controls the heat pump system to implement multiple functional modes. Furthermore, the heat pump unit using the heat pump system provides multiple functions simply by laying a small amount of parts and elements and pipelines outdoors, thereby greatly reducing the engineering cost and cost of parts, and ensuring a much higher water heating efficiency.
