| 摘 要： | 主要进行地源热泵系统的热短路实验研究,对河北工程大学120m埋深地源热泵U型埋管实验室进行冬季性能测试,进行多流量工况的测试,流量分别为4t/h、3.5t/h,3 t/h各运行5 d,地下埋管单位井深换热量也会随著流量的减小而减少;埋管中的流量变化和埋管中的换热量的大小对热短路都有影响.通过热短路分析,提出了改进措施.

| Abstract: | Thermal short-circuiting of the source heat pump system was studied.120 metres U-tube underground heat exchanger performance of Hebei Engineering University in winter was tested.Multi-flow tests of 4t/h,3.5t/h and 3t/h of respective five-day operation were discussed.Heat exchange quantity of per well depth can reduce along with the reduction of the current flow,and some influences of the flow change and the heat exchanger in the tube of underground on thermal short-circuiting were described.To analyze the t... |
