浅析地热尾水热泵技术梯级利用的应用

Application of Cascade Utilization of Geothermal Tail Water Heat Pump Techonology

通过对地热井供热能力的分析,在实际工程中对地热井的能源利用起到指导估算作用。优化地热尾水工艺流程,选用低温采暖末端方式,合理确定供暖设计工况,从而改善地热尾水直接供暖时采暖末端、回水直接排放而造成的能源不能充分利用的现象。根据有地热资源区域的地热尾水利用工程实际案例,通过对地热能源数据分析,结合水源热泵技术,对地热尾水进行梯级利用,可增大地热水的供暖面积,节能环保,对地热井供热能力估算提供工程指导,为有着丰富地热资源的雄安新区冬季供热方式提供了很好的借鉴。

According to the example of geothermal tail water utilization project in the region with geothermal resources,the geothermal tail water can be used step by step through data analysis,combined with water source heat pump technology,which can make full use of geothermal energy,increase its heating area,save energy and protect the environment.It provides a good reference for the winter heating mode in Xiong'an New Area which has rich geothermal resources.
