Embodiment Construction

[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the heat pump system of the present invention will be further described in detail below through embodiments and in conjunction with the drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0033] See figure 1 with figure 2 As shown, the heat pump system of the present invention includes a compressor 100, a first heat exchanger 200, a second heat exchanger 300, an ejector 400, a gas-liquid separator 500, a throttling device 600, a first reversing component, and a second The reversing component and the third reversing component. Among them, the solid arrow indicates the flow direction of the refrigerant in the heating mode, and the dotted arrow indicates the flow direction of the refrigerant in the cooling mode.

[0034] Please keep reading figure 1 As shown,...

Abstract

The invention provides a heat pump system. The heat pump system comprises a compressor, a first heat exchanger, a second heat exchanger, an ejector, a gas-liquid separator, a throttling device, a first reversing assembly, a second reversing assembly and a third reversing assembly. The second reversing assembly and the third reversing assembly are matched with the first reversing assembly so that the heat pump system can be conveniently switched to be under a refrigerating working condition, a heating working condition, a jet-refrigerating working condition and a jet-heating working condition, and the heat pump system can be selectively under the proper operating condition according to the operating situation so as to operate more efficiently, for example, selection of the operating mode of the heat pump system can be determined according to the high-low pressure difference in the operating process of the heat pump system.

Description

Technical field [0001] The present invention relates to the technical field of temperature regulation, in particular to a heat pump system. Background technique [0002] Ejectors are used in many industries. As an effective tool for recovery of expansion work in refrigeration, ejectors can reduce the compression ratio of the compressor, increase the suction pressure, and reduce power consumption. However, because the inlet and outlet directions of the ejector are fixed, it does not work in reverse like an electronic expansion valve or capillary tube. Moreover, the ejector product is designed under constant working conditions. In the actual use environment, the ejector design parameters cannot be automatically optimized to make the ejector The application in heat pump systems is greatly restricted. [0003] Patent application CN200980162048.X discloses that an ejector is added to a conventional heat pump system to realize a variety of cycle control, but the realization of cooling a...
