影响地下环路热交换器设计的地下水流动的理论分析

Theoretical Analysis of Groundwater Flow Affecting Design of Ground-Loop Heat Exchanger

分析了地下水流动对地下环路热交换器设计的影响,介绍了以Pe数作为在地下环路热交换器设计中是否应考虑地下水流动因素的一个判别条件,较详细阐述了地下水流动和传热控制方程及其数学解法。

This paper analyses the effect of groundwater flow on the design of ground-loop heat exchanger. In order to determine whether the groundwater flow factor should be considered in the design of ground-loop heat exchanger, Peclet Number is introduced to be a distinguishing term as well. The paper also particularly illustrates the governing equations of groundwater flow and heat transport. In addition, numerical solutions of the governing equations are discussed.
