摘要
以杭州某地源热泵实际工程为实验平台,结合一套温度测量系统来测定该地区土壤温度年变化规律。测试了冬夏季工况时换热器的进出口水温及地埋管换热器周围的温度分布,分析了地埋管换热器与周围土壤之间的换热状况,确定了该地源热泵系统地埋管换热器的实际换热量。
Takes a ground-source heat pump project in Hangzhou as the experimental platform, and measures the annual change pattern of the soil temperature. Tests the inlet and outlet water temperature of the ground heat exchanger and temperature distribution around it in winter and summer. Analyses the heat transfer between the ground heat exchanger and soil, and obtains the actual heat exchange capacity.
