Schemes of Well Deployment for the Groundwater-Source Heat Pump System
摘要
Abstract
The phenomenon of heat breakthrough is commonly observed in groundwater - source heat pumping. Different schemes of well deployment, in which distances between pumping wells and injection wells are variable, may cause large temperature changes, and further affect the efficiency of the groundwater - source heat pump system. Based on the actual project of the groundwater - source heat pump system in the Zhengzhou Children Hospital, this paper analyzes different schemes with 1 pumping well and 2 injection wells in the aquifer of fine particles. The results show that the best distance between the wells is about 50 m, and the scheme in which the wells are located along a straight line, the natural groundwater gradient is parallel to the line between the puinping well and the injection well, and the gradient is directed to the injection well, will receive the best results.关键词
