摘要
全球地热资源非常丰富。近年来,各种以浅层地热为热源的热泵使用广泛。众所周知,深层地热储量远远大于浅层地热储量,但是对于深层地热的开发尚处于起步阶段。本文针对太原某小区采用深层地热供暖项目进行了实地测试,并对供暖系统测试数据进行了分析。本项目以深层地热作为热源的热泵系统,其系统性能系数为5.83,大于浅层地热系统能效比(1级)限值的60%。
There is abundant geothermal resources globally. In recent years, all kinds of heat pumps using shallow geothermal sources as heat sources are widely used. As we all know, the deep geothermal reserves are far greater than those of shallow ones. But the development of deep geothermal energy is still at the initial stage. In this paper, a deep geothermal heating project was carried out in a residential district of Taiyuan City, and the test data of heating system were analyzed. The heat pump system with deep geothermal as the heat source has the system performance coefficient of 5.83, which is greater than that of the shallow geothermal system（class1） and its limit valueis 60%.
