Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in the figure, a kind of phase-transition heat-storage type air source heat pump assisted solar water device, comprise indoor air cooling heat exchanger 6, indoor air cooling heat exchanger 6 links to each other with outdoor air cooling heat exchanger 3 by four-way change-over valve 5 and expansion valve 8 respectively, also be parallel with rotor compressor 4 on the four-way change-over valve 5, indoor air cooling heat exchanger 6, outdoor air cooling heat exchanger 3, four-way change-over valve 5, rotor compressor 4 and expansion valve 8 have constituted heat pump jointly.On indoor air cooling heat exchanger 6, be parallel with water cold sleeve heat exchanger 7, be parallel with hot water storage tank 9 on the water cold sleeve heat exchanger 7, outdoor air cooling heat exchanger 3 is in parallel with the refrigerant line of phase change heat accumulator 2, be parallel with solar thermal collector 1 on the phase change heat accumulator 2, storage tank 9 is also respectively by in parallel with water cold sleeve heat exchanger 7 and phase change heat accumulator 2 with water circulating pump 10.
Hot water line and refrigerant line are set in the phase transition heat accumulation unit simultaneously, and the hot water line is connected between the import and export pipeline of solar thermal collector, and refrigerant line is then in parallel with the outdoor air cooling heat exchanger of air source heat pump.Switch by the valve on the hot water line, domestic water can either circulate between water tank and heat collector, also can circulate between storage heater and heat collector.And switch by the valve on the refrigerant line, the refrigerant line in the storage heater can be as the condenser of air source heat pump, discharges condensation heat to phase-change material in summer during refrigerating operaton and carries out phase-changing energy-storing.
When the solar radiation in summer was sufficient, solar thermal collector passed through to absorb solar radiation, the domestic water in the heating water tank, if heating is gone down always, water temperature tends to far above needed temperature.Therefore when the water temperature in the water tank reaches design temperature, switch by valve, solar thermal collector no longer be used for continuing in the heating water tank hot water and then carry out phase-transition heat-storage, water circulating pump drives hot water constantly circulation between phase change heat accumulator and solar thermal collector, the heat that phase-change material in the storage heater absorbs in the hot water undergoes phase transition high efficiency energy storage, and is heated once more by the hot water that release heat the has reduced temperature solar thermal collector of flowing through.Because accumulation of heat has been carried out in unnecessary solar radiation, the water temperature in the water tank substantially only remains on needed temperature levels, has reduced the too high high heat that causes of water temperature and has scattered and disappeared; Hot water need not to need mixing cold water to use because water temperature is too high in use, has saved water.The operating temperature of solar thermal collector also decreases, so collecting efficiency is higher relatively, has also prolonged its service life.
Summer the indoor cooling that often needs, domestic air source heat pump through kind of refrigeration cycle, enters outdoor by outdoor air cooling heat exchanger heat by heat in the indoor air cooling heat exchanger absorption chamber.The utility model is provided with refrigerant line in phase transition heat accumulation unit, when air source heat pump carries out indoor refrigerating operaton, can switch by valve, earlier the condensation heat extraction is discharged to phase-change material by the refrigerant line in the storage heater, undergo phase transition behind the phase-change material absorption condensation heat, this part condenser heat is accumulated simultaneously.Also can be with the refrigerant line parallel running in outdoor air cooling heat exchanger and the storage heater, a condenser heat part enters atmosphere, and a part is used to provide phase-transition heat-storage.This phase-transition heat-storage process of carrying out when the air source heat pump refrigerating operaton can be carried out simultaneously with the heat-accumulating process of above-mentioned solar thermal collector, also can carry out alone when no solar thermal collector accumulation of heat.And when overcast and rainy solar radiation deficiency, when solar thermal collector can't make the hot water satisfied temperature need, water is circulated in phase change heat accumulator and in the water tank, by discharging the water in the heat heating water tank that phase transformation accumulates.If it is temperature required that the heat that only depends on phase transformation to discharge can't make water temperature be increased to, then transfer air source heat pump to heating mode, switch air cooling heat exchanger part in the disconnection chamber by valve, and with the water cold sleeve heat exchanger as heat pump condenser, absorption chamber outer air heat is heated to the temperature that needs with heat pump cycle with the water that passes through the phase transformation preheating in the water tank.Because hot water is preheated to uniform temperature by phase-change material, compares the heat pump assisted solar water heating system of no storage heater, the condensation heat load of heat pump reduces, and power consumption also decreases.
Often do not have unnecessary solar radiation winter and be used for accumulating, solar thermal collector absorbs the domestic water in the solar radiation heating water tank with the form work of routine; Domestic air source heat pump is then with heating system operation, and the heat of absorption chamber outer air is also rejected heat in the room by indoor air cooling heat exchanger by heat pump cycle.When intensity of solar radiation was not enough to satisfy the hot water temperature and requires, air source heat pump was then with the heat-pump hot-water mode operation, and absorption chamber outer air heat also discharges condensation heat heating domestic water by heat pump cycle in the water cold sleeve heat exchanger.And at the indoor heating temperature requirement when not being very high, indoor air cooling heat exchanger and water cold sleeve heat exchanger can also use in parallel, and heat pump heats domestic water when heating.Compare with traditional electrical heating auxiliary mode, the auxiliary heating of heat pump is more energy-efficient, meets national energy-saving and emission-reduction principles and policies.
