蓄热型太阳能-地源热泵耦合系统设计

摘要

In this paper a new heat storage coupling system of solar energy and ground source heat pump is designed,in which solar collector can realize seasonal heat storage,heat storage water tank can realize high quality heating in winter and achieve efficient refrigeration in summer.A simulation experiment is carried out to research the new system performance.The results show that the ground heat exchanger and the heat storage water tank can operate intermittently,which is conducive to recovery underground temperature field,increases lifespan of the buried pipe and raises working efficiency of the ground source heat pump.So the new system has obvious economic benefits.%以所设计的新型蓄热太阳能-地源热泵耦合系统为研究对象进行了现场模拟实验,太阳能集热器具有季节性蓄热功能,蓄热水箱可在冬季高品质供暖,夏季实现高效制冷.通过实验研究和经济分析结果显示,系统中地埋管换热器和蓄热水箱间歇运行,有利于地下温度场的恢复,延长地埋管的使用寿命,提高地源热泵工作效率及使用年限,具有明显的经济效益.
