摘要
冬季土壤比环境空气温度要高,稳定性要好,因此以土壤为热源,通过土壤热泵取暖,是一种高节能技术。本文介绍了土壤热泵系统和地下温度场的测试方法,通过阶段试验,对采用塑料和铜地下盘管的土壤热泵的供热能力、性能系数作了比较,并对地下温度场作了研究,为进一步利用土壤热提供了依据。
In winter,the temperature of ground source(ground as a source) is higher and more stable than that of outdoor air.So,in heating mode, the ground coupled heat pump(GCHP)is one kind of highly efficient and energysaving technique. This paper introduces the GCHP systems and the methods of measuring underground temperatures. By the stage expriment, the comparision of heating capacity and the coefficient of performance (cop) between plastic pipes and brass pipes is made. And a study of underground temperature field provides a reference for a further study of ground source.
