单井循环地源热泵系统换热性能试验研究

摘要

In order to study the single well circulation heat transfer performance of ground source heat pump system, the data acquisition monitoring system is utilized to test the system on heat transfer per-formance in Mianyang. With data collection and monitoring system for data acquisition, the single well cir-culation system of the actual heat transfer is calculated finally, the test results show that the average heat transfer is 25 kW that did not meet the design requirements. Problems existing in the system are analyzed with the optimization scheme and suggestion.%为了研究分析单井循环地源热泵系统的换热性能情况，利用数据采集监测系统，对绵阳市某单井循环地源热泵系统进行换热性能测试研究。由数据采集监测系统进行数据采集，最终计算出单井循环系统的实际换热量，测试结果表明该地源热泵系统换热量平均只有25 kW，没有达到初期的设计要求。分析该系统存在的问题，提出优化方案及建议。
