摘　　要： 在对比几种地源热泵系统U型埋地换热器的理论计算模型的基础上,将短时间步温度反应系数模型应用于某小区办公楼的地源热泵系统,对埋地换热器进行了理论分析,并给出了与实验值对比的结果.结果表明,短时间步温度反应系数模型可以较好地预测埋地换热器的换热性能,为地源热泵系统的设计与优化提供了依据. Based on the comparation of some theoretical models of the U-tube heat exchangers of the ground source heat pump, a short time step model of temperature response factor is used in a ground source heat pump system which is employed in an office building,Theoretical analysis of the U-tube heat exchanger and result compared with the experimental values are presented.The result proves that the short time step model can be used to predict heat exchange performance of the underground heat exchanger and to design and optimize a ground source heat pump system.
