摘要
以某工程为例,对其全年吸放热不平衡率进行分析,并通过对两测试井进行夏季工况条件下的地埋管换热性能实验,得出夏季单位井深换热量为 108.5W/m,理论分析冬季单位井深换热量为57.1W/m,最后与常规空调系统进行经济性比较,最终论证该工程实施地源热泵方案的可行性。
The annual suction exothermic unbalanced rate is analyzed with a project in this study, buried tube which is under the summer working conditions in two tests wells is tested for heat exchange performance, which obtains that heat exchange for deep unit in summer is 108.5 W/m. And heat exchange for deep unit in winter in theoretical analysis is 57.1 W/m. Finally, it is compared economically with conventional air conditioning system. Eventually, it is demonstrated that ground source heat pump scheme for the project is feasible.
