Problems solved by technology
[0002] At present, most of the heat pump devices on the market can only meet cooling and heating or simply produce domestic hot water. It can also meet the multi-functional requirements, but it adopts the structure of two-stage condensers in series, which uses the sensible heat of the exhaust, less heat, slow heating speed, low water temperature, large pressure loss, and low efficiency

The invention relates to an all-heat recovery five-working-condition heat pump device which comprises a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger, a first four-way reversing valve, a second four-way reversing and a throttling element, wherein an outlet of the compressor is connected with the end c of the first four-way reversing valve, the end b of the first four-way reversing valve is connected with one end of the third heat exchanger, the end a of the first four-way reversing valve is connected with an inlet of a compressor 1, and the end d of the first four-way reversing valve is connected with the end a of the second four-way reversing valve; the end b of the second four-way reversing valve is connected with one end of the first heat exchanger, the end c of the second four-way reversing valve is connected with an inlet of the compressor, and the end d of the second four-way reversing valve is connected with one end of the second heat exchanger; and the other end of the third heat exchanger is connected with an inlet of the throttling element through a check valve, the other end of the first heat exchanger is connected with a first outlet of the throttling element, and the other end of the second heat exchanger is connected with a second outlet of the throttling element. The device has five functions of refrigeration, heating, domestic hot water, refrigeration hot water and heating hot water.
Description
technical field [0001] The invention relates to a heat pump device, in particular to a five-working-condition heat pump device for total heat recovery. Background technique [0002] At present, most of the heat pump devices on the market can only meet cooling and heating or simply produce domestic hot water. The function is relatively single, and it is almost difficult to meet the requirements of customers for high quality of life. It can also meet the multi-functional requirements, but it adopts the structure of two-stage condensers in series, which uses the sensible heat of the exhaust gas, with less heat, slow heating speed, low water temperature, large pressure loss, and low efficiency. Contents of the invention [0003] The object of the present invention is to overcome the above defects, and provide a five-working mode heat pump device with high heat recovery, high heating speed, high water temperature, small pressure loss and high efficiency. [0004] In order to a...
