一种制造生活热水方法的探讨

摘要

本文针对南方地区土壤源热泵取／排热不平衡的现象，提出了一种消除不平衡的方法，即将过多的热量回收利用来制造生活热水。介绍了该系统的工作原理，并对夏季运行模式进行了实验研究。研究结果表明：出水温度平均可达50℃，同时土壤源热泵埋管换热器周围土壤温度基本得到恢复。此外，该系统还能扩大土壤源热泵系统的应用范围，提高系统的性能系数。%According to phenomenon of imbalance between the heat ejected from soil and the heat absorbed from soil in southern area, a method to eliminate the imbalance that make use of excessive heat to produce domestic hot water is presented. The work principle of system is introduced. And experiments on characteristics of system are conducted under summer condition. The results indicate that the average water temperature of up to 50 ℃. Simultaneously, soil temperature around buried tube heat exchanger of ground source heat pump system is recovered. In addition, the system can also expand the scope of application of the ground source heat pump system and improve the performance of the system coefficient.
