摘要
地层储能技术以低焓地热能作为冷热源,在为室内制冷或供暖的同时,通过系统循环将能量存于储能井中,达到夏热冬用,冬冷夏用的目的。大温差水源热泵技术通过提高供/回水的温差提高水源热泵机组的能效比。将这两种技术联合使用则可以更有效地发挥两者的长处,达到节省、高效利用水资源的目的。以某单位干休所水源热泵工程为例,介绍了此两项技术在工程中的应用。
The technology of aquifer thermal energy storage （ATES） uses a low -medium enthalpy geothermal energy as heat or cold sources. While refrigerating or heating for building, the heat or cold energies will be stored in the energy storage well with the cycle of the system so as to bring about the desired result that the energy from summer is utilized in winter and the energy from winter is utilized in summer. The technology of large temperature difference water source heat pump （WSHP） improves the WSHP units＇energy efficiency ratio by increasing the temperature difference between in/back water. The combined use of these two technologies can take advantages of them more effectively, to achieve the saving and efficient utilization in water resources. Taking the WSHP project in some unit as example, this paper introduces the application of these two technologies in engineering.
