摘要
针对传统的一井抽水多井回灌技术和工艺存在占地面积大、管理不便等问题,在分析目前水源热泵地下能源采集系统问题的基础上,经研究和试验,设计并选择单井抽回两用系统的成井方法,实现了在同一眼井中达到抽取地下水和回灌循环水两种功能。通过设计改进和实际应用及运行,结果表明该系统性能稳定、能量交换效率高、室内温度适宜舒适,达到了预期效果和目的。
The traditional groundwater source heat pump （GSHP） has the problems of occupied large area and complex management. Based on the analysis of heat exchanger of GSHP, it designs a method of completion well of single well pump and reinjection system and realizes the functions of pump and reinjection in one well. The improved design and running result shows that this system has the characteristics of steady performance, high COP and comfortable temperature in door, which achieves expectant effect and goal.
