The deep geothermal heat pump system comprises a heat pump and a controller system, wherein the heat pump and the controller system are connected with a geothermal heat absorbing device through metal pipes, and are connected with a hot water application department through hot water outlet pipes and cold water return pipes; and the geothermal heat absorbing device is 2000m-5000m away from the ground. The deep geothermal heat pump system uses deep geothermal heat resources with higher heat energy, has no influence on atmospheric environment and shallow surface water, and accords with the concept of sustainable development.
Description
Technical field
The invention belongs to art of heat pumps, be specifically related to combined type deep geothermal heat heat pump.
Background technology
General air-conditioning technical develops into now, in operation of air conditioner, is to environment destruction among a small circle, and summer, application made natural environment hotter, and winter, application made natural environment colder, and a use, also affects next door and neighbours.And adopt the principle of heat pump to be that a kind of energy is changed mutually, atmospheric environment is not affected, and convertible heat is large.Current heat pump Problems existing mainly adopts ground shallow-layer thermal energy, need the quantity of shallow well a lot, and required water will carry out growing distance, the circulation of large quality, consumed power is very large, and Long-Time Service easily causes wear and tear in machines, pipeline oxidization, the problems such as oil leak, very likely pollute shallow water source, impact ecology and environmental protection.
Summary of the invention
For problems of the prior art and deficiency, the object of this invention is to provide combined type deep geothermal heat heat pump.Native system only need utilize good thermal medium conduction energy, adopts sealing system, and the material that just can contain huge thermal energy with deep phreatic water, rock, soil etc. carries out energy exchange, decreases the loss of the energy, while not polluted underground water, do not take ground.
The technical solution adopted in the present invention is:
Deep geothermal heat heat pump, heat pump is connected by metal tube with ground source heat absorption plant with controller system, heat pump and controller system and hot water application section gate open superheated water outlet conduit are connected with in cold-water return pipeline, it is characterized in that: described ground source heat absorption plant distance ground 2 km is to 5 kms.
Described connection metal pipe and ground source heat absorption plant all adopt hermetically-sealed construction.
Thermal medium in described metal tube is steam or methyl alcohol or ethanol.
In described hot water effluent's pipeline and cold-water return pipeline, water pump is installed.
The advantage that the present invention has has:
Adopt geothermal heat pump compared with traditional air conditioner technology, be a kind of circulating power conversion, thermal mass is larger, atmospheric environment is not affected, and does not take ground, can effectively utilize and expand green coverage, be the environmental protection energy, meet the direction of sustainable development.
Adopt deep geothermal heat, its heat stores huge, and only need disposable input, maintaining cost is low, can not pollute phreatic water.
Adopt closed conduit structure, effectively can reduce the energy dissipation of thermal medium in pipeline, reduce corrosive pipeline and the pollution of internal heat medium leakage to environment simultaneously.
Adopt steam or ethanol or methyl alcohol as thermal medium, its vaporization calorific value is lower, can effectively reduce the consumption of energy in phase transition process.
In cold hot water piping, add holding water pump can provide more power for the circulation of water, accelerate the carrying out of circulation, water temperature is is reasonably regulated and controled.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Geothermal heat pump system of the present invention, as shown in Figure 1, it comprises metal tube 1, heat pump and controller system 2, ground source heat absorption plant 3, hot water effluent's pipeline 4, cold-water return pipeline 5.Heat pump and being tightly connected with metal tube 1 between controller system 2 and ground source heat absorption plant 3.Heat pump and controller system 2 and hot water application section gate open superheated water outlet conduit 4, cold-water return pipeline 5 is tightly connected.
After power supply is connected, heat pump and controller system 2 are started working, and thermal medium are compressed and absorb thermal energy, thermal medium is liquefied, flow into deeper subsurface by metal tube 1, after carrying out energy exchange with ground source heat material 3, absorb heat, be vaporizated into gas, again by metal tube 1, enter heat pump and controller 2, release after heat through overcompression, liquefaction is liquid again, circulates and so forth.
Meanwhile, heat pump and controller system 2, be used for heat cycles water by the heat absorbed from thermal medium, when water temperature reach 80 to 90 spend time, the hot water such as hot water enters hot water effluent's pipeline 4 by water pump, is transported to factory floor respectively, residence district application department 6.Water after circulating from hot water application department 6, by cold-water return pipeline 5, again enter heat pump and controller system 2, heat of cooling vector gas, and absorption thermal energy is heated into hot water again, enters next circulation.
Ground source heat absorption plant 3 as shown in Figure 2.This device 3 is by n
1to n
nthis n the pipeline composition connected side by side, pipeline has been hermetic, distance ground 2 to 5 km.After thermal medium enters this absorption plant 3 in liquid form, with the deep water of surrounding, rock, the geographical hot material such as soil carries out energy exchange, when vaporizing after the enough heats of absorption, then loss enters metal tube 1, thus completes the utilization to deep geothermal heat energy.
