摘要(Abstract):

建立了地下水源热泵系统实验装置,针对夏季工况和冬季工况分别研究了井水进口温度和井水进出口温差对系统性能的影响。实验结果分析表明,在不同井水进口温度下,合理选择井水进出口温差,可达到在保证系统高效运行的同时节约井水资源的目的。
An experimental device of the ground source heat-pump system has been established,and the influences of the supply temperature of ground water and the temperature difference between supply and return ground water on the heat-pump system have respectively been studied in the summer and the winter condition.The results show that the purpose of both the high efficiency of heat-pump system and the saving of water resource can be achieved if the temperature difference supply between supply and return ground water has been rationally chosen in difference supply temperature of ground water.
