Description
Technical field is the present invention relates to a kind of ground source constant temperature air conditioning of efficient energy-saving and emission-reducing. more specifically, it relates to profit
The new eternal renewable energy utilization technology of heat supply in winter, summer cooling is carried out with superficial-layer geothermal energy to interior.
This celestial body of background technology human living, as a huge hot water bottle, outer cool interior-heat, and is more past
In temperature higher, people call geothermal energy the heat energy that contains in earth interior. shallow layer geothermal energy potential of resource exploitation and utilization is very
Greatly, renewable, the free of contamination advantage of resource, is that any Fossil fuel is irreplaceable.
Mainly two kinds of the geothermal utilization technology of prior art：1st, water source acquisition system, although this technology hot water draws up
Come easily, but recharge go down it is difficult to, be easily caused ground water regime and environmental problem .2, the ground energy heat pump technology such as cannot balance.
Ground energy heat pump technology is its absorption heat or the thermal source for discharging heat near surface formation soil. in winter, ground energy heat pump is from soil
Middle draw heat, supplies the vaporizer of heat pump, improves after temperature through compressor, passes to the condenser of heat pump, to house heat supply；?
Summer, ground energy heat pump absorb heat from house by its vaporizer, are discharged in soil through compressor, condenser. ground energy
Heat pump techniques, where having underground water source, it is not necessary to special ground heat exchanger, can direct groundwater abstraction, through the past
After deimpurity process, according to heating or the purpose of refrigeration, the vaporizer or condenser of heat pump is given, returned after completing heat exchange
It is poured into underground or is discharged into otherwise. where without water source, heat pump will be with soil heat-shift, it is necessary to arrange special
Ground heat exchanger. the ground heat exchanger used by ground energy heat pump is that these pipelines lead in the embedded closed conduct loop of subsurface
Often it is made up of high density polyvinyl-chloride or polybutene plastic tube, heat transferring medium is sent into these underground pipings and underground with pump
Heat exchange is carried out, ground is then return to and is exchanged heat with heat pump, heat transferring medium is usually the saline solution of water, is enclosed in pipeline system
Circulating between system, heat pump on the ground and ground heat exchanger, complete heat exchange task. the defect of ground energy heat pump technology is skill
Art requirement is higher, and equipment investment is larger, needs groundwater abstraction, and being easily caused ground water regime cannot balance, its energy-saving effect
Also only than electric energy air-conditioning economize on electricity 30%～50%.
Content of the invention is present invention aim to overcome above-mentioned deficiency of the prior art, there is provided a kind of energy-efficient
The ground source constant temperature air conditioning of reduction of discharging.
The ground source constant temperature air conditioning of the efficient energy-saving and emission-reducing of the present invention, be using air as heat transfer medium, transfer subsoil water or
, to where required, using the huge heat storage and cold accumulation ability of underground, winter is heat for heat or cold in soil
It is transferred to from subsoil water or soil in building, summer is transferred to the cold of underground in building again, a year is formed
One cooling and heating circulation system, realizes the function of energy-saving and emission-reduction.
The ground source constant temperature air conditioning of the efficient energy-saving and emission-reducing of the present invention is the characteristic cool in summer and warm in winter using stratum, by extracting
With the heat in release stratum, heat supply in winter and summer cooling is realized；In summer, indoor air themperature is higher than in underground shaft
Air themperature in U heat exchange, opens blower motor, and the cold air in underground shaft in U heat exchange is via U heat exchange
→ main exhaust duct → ground energy air conditioner → blower fan → main blast pipe → U heat exchange completes in underground shaft cold sky in U heat exchange
Gas and the exchange of indoor hot-air, realize room temperature lowering cooling, because 5～10 meters of formation temperature is maintained below earth's surface throughout the year
16 DEG C～18 DEG C, so realizing that the effect of room temperature lowering cooling is more empty than electric energy using cold air in U heat exchange in underground shaft
The cold effect of modulation is not bad；Air themperature in U heat exchange in winter, underground shaft is higher than indoor air themperature, by
In warm air in the pipeline of closing natural rising principle, the warm air in underground shaft in U heat exchange is via main exhaust duct
→ ground energy air conditioner flow direction is indoor, and to indoor release heat, cold air inside is via ground energy air conditioner → blower fan → main blast pipe → U-shaped
Heat exchanger tube flows through to supplement, and completes the exchange of cold air inside and warm air in U heat exchange in underground shaft, realizes indoor liter
Temperature heating, as 5～10 meters below earth's surface of formation temperatures maintain 16 DEG C～18 DEG C throughout the year, so, using U in underground shaft
Warm air in type heat exchanger tube realizes that the effect of indoor intensification heating is warm pleasant as spring.
