Abstract:

The groundwater source heat pump system is one of the main ways of shallow geothermal resources development. This paper gives an introduction to HST3D code, which is widely used in China to simulate heat mobilization, and analyzes its advantages and disadvantages. Meanwhile, this paper discusses the application of HST3D code in heat mobilization simulation based on case study on underground water source pump engineering at Zhengzhou Children Hospital. This simulation analyzes the temperature changes in two wells in 8 years, of which the temperature increases no more than 1 Celsius degrees at No.3 well where is near the injection wells, and no more than 0.5 Celsius degree at No.6 well where is relatively far from the injection wells, consistent with real water temperature changes.

Key words:

HST3D; heat mobilization; simulation

摘要：

地下水源热泵系统是利用浅层地温能的一种主要方式，本文介绍了目前国内在浅层地温能研究中应用较广泛的热运移模拟软件——HST3D程序，并结合郑州市儿童医院地下水源热泵实际工程，探讨了HST3D程序在热运移模拟方面的实际应用。模拟并分析了该水源热泵工程运行8年来2口抽水井的温度变化，其中离回灌井较近的3号抽水井温度上升不超过1℃，离回灌井较远的6号抽水井温度上升不超过05℃，与实际水温变化基本一致。
