Air energy heat pump cold-warm-hot integrated equipment

Abstract

The invention discloses air energy heat pump cold-warm-hot integrated equipment. The equipment absorbs heat around an evaporator to evaporate a heat transfer working medium; the steam of the working medium is compressed by a compressor, and then the temperature and pressure thereof are increased; when the high-temperature steam is condensed into liquid by the condenser, heat is released and transferred to the water in a water storage tank; and the condensed heat transfer working medium returns to an evaporator through an expansion valve and then is evaporated again to finish a heating cycle. Comparatively, a low-temperature low-pressure liquid refrigerant firstly absorbs heat from a low-temperature heat source in the evaporator and is gasified; then a compressor extracts the gasified refrigerant gas in the evaporator and compresses the refrigerant gas in the condenser, and the refrigerant gas turns into high-temperature high-pressure gas; the high-temperature high-pressure gas is condensed into liquid in the condenser and turns into a high-temperature high-pressure liquid refrigerant; and the high-temperature high-pressure liquid refrigerant is throttled by the expansion valve to become a low-temperature low-pressure liquid refrigerant to finish a refrigeration cycle. The system can meet all requirements of domestic heating, hot water supply and refrigeration.

Description

technical field [0001] The invention relates to an air energy heat pump integrated cooling, heating and heating equipment. Background technique [0002] At present, household refrigeration is mainly carried out by air conditioners, and the air conditioners consume a lot of power and cannot play the role of energy saving. The supply of hot water and heating must be replaced by other facilities. At the same time, the existing cold and heat pumps on the market using the principle of water circulation have complicated unit structures, unsatisfactory cooling effects, instability, inability to supply heating, cumbersome maintenance, and most of them use high-power units, which cannot be used by home users. implemented in. Contents of the invention [0003] In order to solve the problem of heat pumps on the market for household cooling, heating, and heating, the present invention proposes an air-energy heat pump cooling, heating and heating integrated device that can realize hou...
