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.

The specific embodiment

As shown in Figure 1, the heating integrated equipment of air energy heat pump changes in temperature, technical scheme of the present invention is: the heating integrated equipment of air energy heat pump changes in temperature; It is characterized in that: evaporimeter 6,7 front ends are installed 2 tunnel guiding control valves 4,9, freeze, when heating water, and guiding control valve 4,9 switches; The guiding control valve will be opened, and cold-producing medium gets into the pipeline of 6 indoor evaporator from fluid reservoir 11 after through expansion valves 5 throttlings through balance filtration device 10, simultaneously closed refrigerant through expansion valve 8 throttlings after towards the pipeline of 7 outdoor evaporimeters; When the cold-producing medium of low-temp low-pressure through inlet chamber after the expansion valve throttling in evaporimeter, exchange through blower fan and room air, thus the reduction indoor temperature; To reach the requirement of refrigeration; Filter through refrigerant purity filter 3 through the cold-producing medium after the heat absorption, after returning compressor 2 and doing work, the cold-producing medium that generates HTHP gets into the condenser 1 in 12 water tanks; Carry out heat exchange with the cold water in the water tank; Improve water temperature, so that use, the liquid state entering fluid reservoir 11 that the cold-producing medium after the heat exchange becomes low-temp low-pressure comes and goes circulation.Hot water in 12 water tanks is connected with bathroom 13, kitchen 14, has therefore also just satisfied the effect of home-use domestic hot-water and cold air.

When heating water, heating, guiding control valve 4,9 switches, and the guiding control valve is opened; Cold-producing medium gets into the pipeline of 7 outdoor evaporimeters after through expansion valves 8 throttlings through balance filtration device 10 from fluid reservoir 11; 5 throttlings get into the pipeline of 6 indoor evaporator to closed refrigerant through expansion valve simultaneously, and evaporimeter outside inlet chamber after the cold-producing medium process expansion valve throttling of low-temp low-pressure exchanges through blower fan and outdoor air; Filter through refrigerant purity filter 3 through the cold-producing medium after the heat absorption; After returning compressor 2 and doing work, the cold-producing medium that generates HTHP gets into the condenser 1 in 12 water tanks, carries out heat exchange with cold water in the water tank; To reach the effect that improves water temperature, the liquid state entering fluid reservoir 11 that the cold-producing medium after the heat exchange becomes low-temp low-pressure comes and goes circulation.Hot water in the water tank connects domestic hot water's pipeline and indoor superconducting radiator 15, and indoor superconducting radiator carries out heat release to indoor low temperature chamber gas, to improve indoor temperature, has therefore also just satisfied the effect of home-use hot water and heating installation

The present invention through evaporimeter from surrounding environment draw heat with evaporation heat transfer working medium; Working substance steam temperature and pressure after compressor compresses rises, when high-temperature vapour becomes liquid through condenser condenses, the heat transferred that discharges the water in the storage tank; Condensed heat-transfer working medium turns back to evaporimeter through expansion valve; And then be evaporated, move in circles, so just accomplish one and heat circulation; Comparatively speaking, the liquid refrigerant of low-temp low-pressure at first absorbs heat and gasification from low-temperature heat source in evaporimeter; Compressor extracts the refrigerant gas after gasifying in the evaporimeter and is compressed in the condenser then; This moment, refrigerant gas became high temperature and high pressure gas, and this high temperature and high pressure gas is cooled in condenser and condenses into liquid, becomes the high-temperature high-pressure liquid cryogen; Become the low-temp low-pressure liquid refrigerant through the expansion valve throttling again, so just accomplish a kind of refrigeration cycle.According to above cold and hot law, this cover system can satisfy domestic heating fully, hot-water supply, the requirement in all directions of refrigeration.
