摘要
地下埋管换热器是地源热泵空调系统的核心部分,其换热性能的好坏直接影响地源热泵的工作效率和经济性能。本文结合了近些年来国内外对地下换热器的实验和模拟研究成果,对影响其换热性能的主要影响因素进行全面的分析,旨在为地源热泵系统的优化设计和运行提供科学的参考依据。
The underground heat exchanger is the core part of ground source heat pumb (GSHP) air conditioning system, and its heat transfer performance affects the work efficiency and economic perform- ance of ground source heat pumb (GSHP) directly. This paper combines the experiments and simula- tions of heat exchanger at home and abroad in recent years, and makes a comprehensive analysis of the main influencing factors about heat exchange performance, aiming at providing a scientific basis to the optimization of the design and operation of ground source heat pumb (GSHP) system.
