At present, earth source heat pump has been a kind of comparatively mature technique, external existing a lot of case histories of Northern European countries particularly, and domestic also had successful application, and demonstrated its superperformance aspect energy-conservation gradually.Earth source heat pump is to utilize geothermal energy to freeze, heat a kind of aircondition of circulation as thermal source.It has advantages such as heat output is stable, COP value height, good effect of heat exchange, set structure compactness.Utilize earth-source hot-pump system to building cooling or heat supply, made full use of geothermal energy, reduced consumption the high-order energy.Not only practiced thrift the energy, and reduced environmental pollution, in addition because earth source heat pump unit high efficiency.The machine room floor space is little, greatly reduces operating cost.Therefore the geothermal energy air-conditioning system that is used for building as regenerative resource has obtained everybody approval, and its domestic application increases gradually.At present, utilize the instance of earth-source hot-pump system for building cooling, the more existing application of heat supply.Utilize the temperature difference of soil and environment to obtain heat energy and have very huge energy resource prospect.The characteristics of the energy-saving and environmental protection of earth-source hot-pump system are to heat, the air-conditioning technical new trend of refrigeration.
Problems such as yet traditional earth-source hot-pump system also exists condensation temperature and evaporating temperature changed by ground temperature usually and changes, and the backfilling material thermal resistance is high, system's first cost is used the heating refrigeration weak effect greatly, for a long time, service life is short.Add differences such as each department geographical conditions, material, equipment, technology; Causing designing unreasonable, be not the investment that causes great number, form huge waste, is exactly that capacity is not enough; It is saturated to reach heat in a short time; System is scrapped, and perhaps system's each several part does not match, and can not bring into play the due huge advantage of earth source heat pump.
Summary of the invention
In order to solve and above-mentioned technical problem, the invention provides a kind of environmental protection, energy-conservation, low energy consumption, the band ground thermal balance of low operating cost and the solar-energy air-energy earth source air conditioner device of energy storage device.
The technical scheme that the present invention solves the problems of the technologies described above is: comprise solar thermal collector, air source cooling tower, source pump, underground buried tube, air conditioner user end, first motor-driven valve, second motor-driven valve, the 3rd motor-driven valve, the 4th motor-driven valve, the 5th motor-driven valve, the 6th motor-driven valve, the 7th motor-driven valve, the 8th motor-driven valve, the 9th motor-driven valve, the tenth motor-driven valve, the 11 motor-driven valve, first water pump, second water pump, the 3rd water pump and the 4th water pump; Described source pump, the 4th motor-driven valve, the tenth motor-driven valve, the 11 motor-driven valve, underground buried tube, water replanishing device, the 3rd water pump, the 3rd motor-driven valve and the 5th motor-driven valve connect and compose unit side major loop; Described solar thermal collector, the 6th motor-driven valve, first water pump, the 7th motor-driven valve are formed a supplementary set hot loop and are inserted unit side master water supply loop; Described air source cooling tower, the 8th motor-driven valve, second water pump, the 9th magnetic valve are formed an auxiliary cooling circuit and are inserted unit side master water supply loop, and described source pump, first motor-driven valve, the 4th water pump, second motor-driven valve and air conditioner user end connect and compose the user side loop.
Technique effect of the present invention is: environmental protection of the present invention, energy-conservation, low energy consumption, low operating cost, practical and convenient are a kind of heating and cooling equipments preferably.The present invention injects the under ground portion of traditional buried tube type soil source heat pump respectively with heat in low level heat energy solar energy and the air ability and cold in different time, Various Seasonal, balance round the clock, summer in winter with heat with cold uneven situation.And store a part of heat (or cold) in advance in heating (or cooling) use in season, help improving the heating refrigeration effect.
