Characteristics of the present invention:
1, through using underground water-bearing structure layer to descend coolant-temperature gage more consistently the whole year, long-term mean temperature is lower than summer temperature and is higher than winter temperature, can increase substantially the efficient of source pump.
2, underground water-bearing structure layer mainly is made up of coarse sand, gravel, and its volume and quality are huge, and the thermal capacitance performance is powerful and adiabatic with the external world.Is storage body through underground energy-accumulation circulation with the underground water-bearing structure layer in whole project plot, useless cold type to the underground storage in winter can be improved the operating mode of source water of the source pump refrigeration in summer in the coming year; The used heat in summer is drained into underground storage can improve the source water condition that the source pump in winter heats.
3, energy-storage cold and hot well circulation in 1: 1; Can not only efficiently utilize groundwater resources to solve to utilize in the ground water engineering one to get many times problem, and cold and hot well is according to cooling--heat supply of storage cold-peace--, and the requirement of heat accumulation is carried out positive and negative circulation and has been avoided the cold cycling well by the sandstone blocking problem.
4, accumulation of energy face portion complete closed circulation circularly; Through plate type heat exchanger energy is flowed to that underground water is in the unglazed environment of anaerobic fully in the whole process of source pump, avoided underground water to change obstruction and the pollution that causes cold and hot well because of photochemical reaction causes quality of groundwater.
5, energy-storage cold and hot source well reaches and takes energy and stored energy dynamic equilibrium through the thermal equilibrium control of ground system.Be beneficial to and reach thermal balance, can not cause underground hot stack.
6, be provided with many group subsurface temperature sensors in the accumulation of energy district, monitor the temperature of underground water-bearing structure layer and analyze the situation of change of underground temperature field through practical operation situation.
7, the endless form of accumulation of energy circulation gang of wells is through self-adaptation measurement and control system, and the mode of operation of accumulation of energy circulation gang of wells is adjusted in the variation of the cooling and heating load amount that causes according to the various external environments of building and personnel's dense degree, accomplishes intelligent circulation.
Beneficial effect: shallow earth that the present invention utilizes can belong to geothermal energy, and shallow earth can comprise storage power and rock soil mass in the rock soil mass the energy in moisture.Store cold/heat in the same water-bearing structure layer in same plot in the heat/cold that accumulation of energy circulating technology of the present invention is medium with water in extracting underground water-bearing structure layer; Neither change the temperature field of underground water-bearing structure layer; Also exhaust emission underground water is not suited measures to local conditions, protectiveness ground reasonable development geothermal energy.
For having suitable underground water-bearing structure layer plot, all can be building air conditioning cooling heat and domestic hot-water through the accumulation of energy recycle shallow earth of underground water-bearing structure layer; The Cooling and Heat Source well seals the underground water-bearing structure layer of use of recycling-guard property fully, only utilizes the energy of water-bearing structure layer and does not discharge not polluted underground water; Through underground energy-accumulation circulation useless cold type to the underground storage in winter can be improved summer in the coming year the source pump refrigeration source water operating mode, the used heat in summer is drained into underground storage can improve the source water condition that the source pump in winter heats, can guarantee that the heat pump long-term stability moves efficiently.
