摘要

通过建立“地面-水平地面换热器-换热剂”系统的三维传热模型,对作为热泵系统组成部分的卧式多回路换热器的效率进行了分析。根据数值模拟结果,确定了地下换热器出口换热剂温度与地下取热量的时间依赖关系。该模型的计算结果与实验数据吻合较好。

UNSTEADY HEAT TRANSFER IN A HORIZONTAL GROUND HEAT EXCHANGER
By the three-dimensional model of heat transfer in the system "ground - horizontal ground heat exchanger - heat transfer agent", an analysis of the efficiency of the horizontal multi-loop heat exchanger, which is an element of the heat pump system, was carried out. Based on the results of numerical simulation, the time dependence of the heat transfer agent temperature at the outlet from the ground heat exchanger and the amount of heat extracted from the ground is determined. The results of calculations by the presented model are satisfactorily agree with the experimental data.
