土壤源热泵在空调系统中应用分析研究

摘要

Ground-source heat pump (GSHP) uses thermal energy which is stored in the underground soil layer to supply heat and cooling. GSHP is known as a new type air-conditioning technology on low-carbon, energy-saving and environmental one. The basic operating principle, the composition of pipe system, classification and some technology characteristics of GSHP were all introduced briefly. Combined with the example of small buried pipe operation of GSHP engineering, both the analysis and the research were made comprehensively about GSHP application and development in China. Some technical problems on the development process are pointed out herein.%　　土壤源热泵是利用地下土壤层中储存的热能来进行供热和制冷的一种低碳节能高效环保的新型空调技术。简要介绍了土壤源热泵工作基本原理、管路系统组成、分类及其一些技术特点，并结合小型地埋管土壤源热泵工程运行工况实例，通过综合分析研究得出土壤源热泵技术在我国应合理适度开发利用，并指出了其发展过程中存在的一些技术问题。
