The invention discloses a triple heat pump system, comprising a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger and at least one throttling device, the outlet of the compressor is connected to the outlet of the first heat exchanger respectively. The first port, the first port of the second heat exchanger and the first port of the third heat exchanger are connected by pipelines, and the inlet of the compressor is connected with the first port of the second heat exchanger and the first port of the third heat exchanger respectively. One port is connected through a pipeline; the first heat exchanger is provided with a domestic hot water outlet and a make-up water inlet, and its second port is respectively connected to the second port of the second heat exchanger and the second port of the third heat exchanger through the device. There is a pipe connection with a throttling device; the second port of the second heat exchanger has a pipe provided with a throttling device for being connected with the second port of the third heat exchanger when cooling; the second port of the third heat exchanger The port has a pipe provided with a throttling device for connecting with the second port of the second heat exchanger during heating. The system can provide hot water during cooling and heating.
Description
technical field [0001] The invention relates to the field of heat pump systems, in particular to a triple heat pump system. Background technique [0002] The triple heat pump system in the prior art, such as the utility model patent with the patent No. CN 201866990U, can be used as an air conditioner, and it can simultaneously make hot water in the cooling mode, realize full heat recovery, and provide people with life hot water. However, it has the disadvantages of complex structure, high cost and poor reliability, and when it is heating for users in the heating mode, domestic hot water cannot be produced, which brings certain inconvenience to people's lives. Contents of the invention [0003] In order to overcome the disadvantages of the prior art above, the present invention provides a triple heat pump system, which can provide domestic hot water to users during cooling and heating, and has a simple structure. [0004] The technical solution of the present invention is...
