Embodiment Construction

[0031] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. For example, although the embodiment of the present invention takes the first throttling element as an electronic expansion valve as an example, those skilled in the art can adjust it according to needs so as to adapt to specific applications, as shown in Section 1 Flow elements may also be thermal expansion valves, capillary tubes, and the like. Obviously, the adjusted technical solution will still fall into the protection scope of the present invention.

[0032] It should be noted that, in the description of the present invention, terms such as "left", "right", "inner", "outer" and other indicated directions or positional relationships are ba...

Abstract

The invention relates to the technical field of heat pumps, and particularly provides a heat pump system. The heat pump system aims to overcome the defects of an existing air source heat pump system and an existing solar heat pump system. The heat pump system involves an enhanced vapor injection compressor, a first four-way reversing valve, an indoor heat exchanger, an electronic expansion valve,an outdoor heat exchanger, a plat-plate solar collector and a first throttling element which are connected through a pipeline, the communication modes of four connectors of the first four-way reversing valve and the opening and closing states of the electronic expansion valve are switched, the enhanced vapor injection compressor, the outdoor heat exchanger, and the indoor heat exchanger can form arefrigeration circuit, the enhanced vapor injection compressor, the indoor heat exchanger, the plat-plate solar collector and the outdoor heat exchanger can form a heating circuit, and the flat-platesolar collector in the heating mode can be used for supplying gas to the compressor, and the indoor heat exchanger is provided with a water supply pipeline capable of exchanging heat with the indoorheat exchanger. Refrigeration, heating and cold / hot water supply are efficiently realized through the ingenious combination of the flat-plate solar collector and the air source heat pump.

Description

technical field [0001] The invention relates to the technical field of heat pumps, and specifically provides a heat pump system. Background technique [0002] As a high-efficiency energy-saving device that makes full use of low-grade heat energy, heat pumps are widely used in people's daily life and industrial production. There are three main types of heat pumps: air source heat pumps, water source heat pumps and ground source heat pumps. Among them, air source heat pump systems are the most common, such as air conditioners widely used in people's lives, and air source heat pump water heaters used in public places. However, in areas with low winter temperatures, the heating efficiency of air source heat pumps is very low, and the heat pump units usually cannot reach the rated heating capacity to meet the needs of users, resulting in poor user experience. [0003] With the advancement and maturity of technology, solar heat pump systems have appeared on the market. Solar he...
