摘要
该项目以地热水间接换热,在地热水供热量不能满足负荷时,采用高温水源热泵系统对地热尾水的热量进行回收,从而增加了地热水的梯级利用。同时本文对该方案与常规供暖方式的运行费用进行了比较。
Geothermal water is used indirectly in this heating system. When the heating output of geothermal water is not sufficient, a high-temperature water source heat pump system is used for the reclaim of geothermal tail water to guarantee the cascade application of energy sources. Besides, operating cost is compared with convectional heating systems.
