Description
Technical field
The utility model belongs to air conditioner energy saving and field of renewable energy resource utilization, especially relates to a kind of ground heat exchanger technology that is arranged in the basement.
Background of invention
Water resource heat pump is to have utilized earth surface or shallow-layer water source as Cooling and Heat Source, carries out the heating air-conditioner system of power conversion.Earth surface water source and soil are huge solar thermal collectors, have collected 47% solar energy, utilize human every year more than 500 times of energy.Now, human society has entered the stage of calling sustainable development, and this utilization of water resource heat pump is stored in shallow surface and is close to unlimited regenerative resource and provides the technology of warm air conditioner, the undisputed a kind of form that becomes renewable energy utilization for the mankind.
A thermal source of water source heat pump system is the surface water in pond, lake or the river small stream.Utilizing these natural waters in the place near big scale of construction natural waters such as rivers,lakes and seas is the form of considerable a kind of air-conditioning heat pump as the low-temperature heat source of heat pump.Certainly, this surface water heat pump system also is subjected to the restriction of natural conditions.In addition, because the surface water temperature is subjected to climatic influences bigger, similar with air source heat pump, the heating load of heat pump is more little when environment temperature is low more, and the coefficient of performance of heat pump also can reduce.The cooling and heating load that certain surface water body can be born is relevant with multiple factors such as its area, the degree of depth and temperature, need calculate as the case may be.The heat exchange of this heat pump also needs to take in advance to the influence of ecological environment in the water body sometimes.
Another thermal source of water source heat pump system is the underground water that extracts from well or discarded mine.Underground water through heat exchange can enter the surface water system, but requires usually by inverted well groundwater recharge to be arrived original water table for bigger application item.But, use this groundwater heat pump system and also be subjected to many restrictions.At first, this system needs abundant and stable groundwater resources as prerequisite.Therefore before adopting groundwater heat pump system, need do detailed survey for the purpose of locating hydrogeological resources in advance and beat the exploration well, to obtain data such as subsurface temperature, groundwater depth, water quality and water yield, the economy of groundwater heat pump system and the degree of depth of water table have very big relation, if level of ground water is lower, not only the expense of Cheng Jing increases, and the power consumption of water pump in service will reduce the efficient of system greatly; Be subjected to the bigger well of ground environment temperature effect etc. as employing, the heat exchange efficiency aggregated loss of system is increased.In addition, though the underground water of Chou Quing will recharge water table in theory, but that is that all right is ripe for existing at present groundwater recharge technology, the speed of recharging under a lot of geological conditions is significantly less than the speed of drawing water, all recharged in the water-bearing layer again through being difficult to behind the heat exchanger from underground water of releasing, caused harm such as the loss of groundwater resources and surface subsidence.
