摘要
结合实际工程项目,对对井抽灌热泵耦合地下含水层储能效果进行了研究与评价。结果表明热泵耦合含水层储能系统能够充分利用浅层地能资源,实现冬灌夏用和夏灌冬用的储能作用,节能效果显著。但是,在冷热负荷不平衡的情况下,若系统长期运行会造成采井或灌井周围温度的降低或升高。因此,为了保护地下生态平衡,系统应尽量在冷热负荷均衡的工况下运行。
The effect of heat pump Coupled aquifer thermal energy storage on a heating and air-conditioning for a hotel of Tianjin was investigated. The data of the thermal energy storage system were got and analyzed. The results indicate that heat is abstracted from pumping well water and cold is injected to the injection-well water through heat pump in winter, which cold can be stored up and used in summer; and on the contrary, cold is abstracted from pumping well water and heat is injected to the injection-well water through heat pump in summer, which heat will be stored up and used for the heat pump in winter. Thermal energy contained in shallow earth is used. It also indicats that the temperature of the un- derground will fall if the heating load is heavier than the cold load and the temperature of the underground will rise if the heating load is lower than the cold load. In order to protect the aquifer environment balance, it is the best that the system should be running in the ease that the heat load equal to the cold load.
