Description

Solar-energy air-energy air conditioner

Technical field:

The utility model relates to a kind of equipment that utilizes solar energy, air to freeze, to warm oneself.

Background technology:

Heat pump air conditioner can not heat under-5 ℃ cryogenic conditions substantially at present, the efficient that heats obviously descends, the high-efficiency cold-hot switching performance of air source heat pump can not get fully playing, and can not use substantially at north of china in winter and night, and the effective rate of utilization of heat pump air conditioner is very low.

Summary of the invention:

In order to solve the problem of above-mentioned existence, the utility model provides a kind of and can heat under cryogenic conditions, the solar-energy air-energy air conditioner that cold and hot switching performance is good; The purpose of this utility model is achieved through the following technical solutions: solar-energy air-energy air conditioner, in cooling water tank (10), be provided with heat exchanger (11), air source heat pump (9), air source heat pump (9) by pipeline respectively with soak water tank (6) in heat exchanger (7) and main absorber plate (1) be connected, on the export pipeline of air source heat pump (9), be provided with four-way change-over valve (8), the heat exchanger (7 of soak water tank (6) and attemperater (5), 4) connect by pipeline, the heat exchanger (4) of attemperater (5) is connected with main absorber plate (1) by pipeline (12), on pipeline (12), be provided with choke valve (3), main absorber plate (1), secondary absorber plate (2) is by the thin aluminum sheet of vertical arrangement, copper pipe constitutes, copper pipe laterally interts between thin aluminum sheet, and main absorber plate (1) is connected by pipeline with secondary absorber plate (2).

The beneficial effects of the utility model: the utility model has solved existing heat pump air conditioner under the work condition environment of low temperature and high temperature, the difficult problem that cold and hot exchange efficiency is low, in the winter time-20 ℃ with interior low temperature, 40 ℃ of summers are with interior high temperature, the cooling and warming effect of this product obtains performance as usual, the average Energy Efficiency Ratio of hot water of heating 150L is more than 3.3 times, minimum Energy Efficiency Ratio is 2, high energy efficiency ratio is more than 4, utilize solar energy and air can be able to produce a large amount of 50-60 ℃ hot water, save cost, the utility model replaces traditional inefficient heating equipment, convenient to use, save a large amount of energy and water resource.

Description of drawings:

Fig. 1 is the structural representation of solar-energy air-energy air conditioner.

The specific embodiment:

As shown in the figure, solar-energy air-energy air conditioner, in cooling water tank 10, be provided with heat exchanger 11, air source heat pump 9, the water surface elevation of cooling water tank is lower than the air heat source pump, difference in height is 50mm, promptly abate the noise, played cooling again, heat effect, air source heat pump 9 is connected with heat exchanger 7 and main absorber plate 1 in the soak water tank 6 respectively by pipeline, on the export pipeline of air source heat pump 9, be provided with four-way change-over valve 8, the heat exchanger 7 of soak water tank 6 and attemperater 5,4 connect by pipeline, the heat exchanger 4 of attemperater 5 is connected with main absorber plate 1 by pipeline 12, on pipeline 12, be provided with choke valve 3, main absorber plate 1 is by the thin aluminum sheet 13 of vertical arrangement, copper pipe 14 constitutes, copper pipe 14 laterally interts 13 of thin aluminum sheets, secondary absorber plate 2 is by thin aluminum sheet 15, copper pipe 16 constitutes, its structure is identical with the structure of main absorber plate 1, leading, spray selective coating on the secondary absorber plate, hundreds of thin aluminum sheets have formed the intensive blackbody cavity of large tracts of land, main absorber plate is totally three comb roads, on the middle comb road auxiliary connection absorber plate pipeline, the quick flowing heat transfer of secondary absorber plate medium depended on pressure difference, main, when secondary absorber plate heats as evaporimeter, during refrigeration as condenser.

The air source heat pump 9 generation high temperature and high pressure gas of starting working during work, pass through gas exhaust piping, be transported to heat exchanger and carry out heat release for 7 kinds, 50-60 ℃ of hot water of soak case 6 insulation energy storage, be delivered to by heat exchanger 7 again and carry out the secondary heat release in the heat exchanger 4, temperature is reduced to 25-30 ℃, arrive choke valve 3 by gas exhaust piping, reduce the flow of cold-producing medium, decrease temperature and pressure, medium temperature in the main absorber plate pipeline is significantly less than airborne temperature, absorb a large amount of heats, produce very low low temperature environment around the main absorber plate, the temperature and pressure of so secondary absorber plate is higher than main absorber plate, and to main absorber plate supply heat, the circulation that goes round and begins again of pressured difference, during air source heat pump work, secondary absorber plate is work just, otherwise just quit work, when freezing summer, by the four-way change-over valve commutation, the outside heat release of main absorber plate, and medium temperature in the secondary absorber plate pipeline and pressure are lower than main absorber plate, secondary absorber plate is the outside heat release of circulation fast at any time also, reduce main absorber plate temperature as early as possible, the gas that sucks by the pipeline heat pump produces high temperature and high pressure gas by compression again, finishes a circulation.
