摘　　要：土壤源热泵作为一种可再生能源应用系统,与传统热水系统相比有显著降低能耗的优势。以广西某学校的两个不同校区土壤源作为研究对象,通过在不同的季节实地采集的数据,分析比较了在直热和循环加热两种不同的运行模式下的土壤源热泵供热水系统的运行状况。得出在不同的需求下应该采用怎样的土壤源热泵系统的运行模式,为今后土壤源热泵的节能运行提供参考依据。As a renewable energy application system,ground source heat pump has the advantage of significantly reducing energy consumption compared with traditional hot water system.This paper takes the soil source system of two different campuses of a school in Guangxi as the research object,through collecting a large number of data in different seasons,analyzes and compares the operation status of ground source heat pump heating water system under two different operation modes of direct heating and circulating heating.The operation mode of ground source heat pump system under different demands is discussed.It provides a reference for the energy-saving operation of GSHP in the future.
