The beneficial effects of the utility model are that ground energy, solar energy are extracted in the compartment of terrain, so system can energy-efficiently move.
The utility model compared with prior art has the following advantages:
1, solar energy, can belong to regenerative resource, help sustainable development.The ground energy,
1, solar energy, can belong to regenerative resource, help sustainable development.Ground energy, solar energy use at interval, complement each other, and system can energy-efficiently be turned round all the time.
2, directly evaporation heat absorption in the solar energy heating copper pipe of cold-producing medium, its evaporating temperature be below-20 ℃, therefore, not only can efficient absorption solar irradiation energy, can also absorb the heat of ambient air in a large number.
3, at low temperature overcast and rainy day weather, the solar energy heating pipe evaporator also can absorb a large amount of heat energy from rainwater, air.

The specific embodiment:
Below in conjunction with accompanying drawing specific embodiments of the present utility model is described in further detail:
The utility model is connected with an end of domestic hot-water's heat exchanger 2 with the exhaust outlet of copper pipe with refrigeration compressor 1, the other end of domestic hot-water's heat exchanger 2 is connected with an end of cross valve 6, the other end of cross valve 6 respectively with condenser 5, magnetic valve 16 connects, condenser 5 is connected with device for drying and filtering 7 and restricting element 10 with the other end of magnetic valve 16, device for drying and filtering 7 and check valve 8, restricting element 9 is chained together, restricting element 10 and check valve 11, device for drying and filtering 12 is chained together, the other end of restricting element 9 and device for drying and filtering 12 links to each other with an end of evaporimeter 13, the other end of evaporimeter 13 links to each other with an end of cross valve 6, the other end of cross valve 6 respectively with magnetic valve 17, one end of solar energy heating pipe evaporator 18 links to each other, magnetic valve 17, the other end of solar energy heating pipe evaporator 18 links to each other with an end of gas-liquid separator 15, and the other end of gas-liquid separator 15 links to each other with the air entry of compressor 1.
Under the operating mode that heats in the winter time, condenser 5 is made evaporimeter usefulness, if condenser 5 is water cooled condensers, ground heat exchanger 4 is connected with the water inlet pipe and water outlet pipe of condenser 5, the heat energy of absorption refrigerating water is evaporated in the winter refrigeration agent in condenser 5, chilled water is recycled to ground heat exchanger 4, absorbs underground heat energy.Under the operating mode that heats in the winter time, evaporimeter 13 is made condenser usefulness, if evaporimeter 13 is water-cooled evaporimeters, water pipe 14 is connected to indoor heating with the indoor fan coil pipe.Domestic hot-water's heat exchanger 2 is used for making life hot water.
Show that after deliberation the continuous drawing geothermal energy can make underground frozen soils temperature reduce gradually, source pump efficient decreases, and best bet is exactly to extract at interval.The utility model can be made domestic hot-water and heating with utilizing separately, also can use solar energy system domestic hot-water and heating separately, or use simultaneously solar energy, can make domestic hot-water and heating.
Be described further below in conjunction with 2 pairs of courses of work of the present utility model of accompanying drawing; Use the course of work of solar energy daytime separately: magnetic valve 16 leaves, and magnetic valve 17 closes.During compressor 1 work, high steam is discharged from exhaust outlet, through domestic hot-water's heat exchanger 2 heat release system domestic hot-waters, through cross valve 6, evaporimeter 13 heat releases heating, arrive magnetic valve 16 after drying filter 12, check valve 11, energy saving component 10 step-downs, cross valve 6, steam raising in solar energy heating pipe evaporator 18, heat absorption are also got back to compressor 1 air entry through vapour liquid separator 15, finish a working cycles.Compressor 1 is successively worked, and heat is emitted the system domestic hot-water or emitted heating from evaporimeter 13 from domestic hot-water's heat exchanger 2 just constantly by 18 inspirations of solar energy heating pipe evaporator.Because cold-producing medium is in evaporation below-20 ℃, not only can absorb the heat of solar radiation, can also absorb the heat of a large amount of surrounding airs, therefore, the thermal efficiency can be very high.
Use the geothermal energy course of work evening separately: magnetic valve 16 closes, and magnetic valve 17 leaves.During compressor 1 work, high steam is discharged from the exhaust outlet of compressor 1, carry out heat exchange through domestic hot-water's interchanger 2 and heat water, heat to evaporimeter 13 heat releases through cross valve 6 again, drying filter 12, check valve 11 is to restricting element 10 throttling step-downs, refrigerant gas is in condenser 5 evaporation gasification heat absorptions, the heat energy that absorption refrigerating water is brought up from ground heat exchanger 4, refrigerant gas after the heat absorption is through cross valve 6, magnetic valve 17, gas-liquid separator 15 are got back to compressor 1 air entry, finish a working cycles.Compressor 1 continuous operation, underground heat energy just continuously by from ground heat exchanger 4 inspirations, are discharged into domestic hot-water's heat exchanger 2 and heat water and evaporimeter 13 heating.
Utilize simultaneously solar energy, can the time the course of work: magnetic valve 16,17 cuts out simultaneously, and other are identical with preceding two processes.
