地源热泵岩土热物性测试简介与分析

地源热泵系统作为利用可再生能源的暖通空调技术,具有节能、环保等优点,在世界范围内被广泛使用。土壤作为地源热泵系统的冷热源,对整个系统有着至关重要的影响。不同建筑负荷特性要求系统对土壤的取放热量不同,二者的不平衡会使土壤的温度发生变化,影响整个系统的运行。对特定建筑地源热泵系统土壤的热物性测试是设计地埋管系统的重要依据。本文对热物性测试的理论依据进行了简单介绍,并对具体事例进行了分析计算,得出岩土体的导热系数等具体热物性参数,为地源热泵系统的精确设计提供了依据。

Introduction and analysis of ground source heat pump geotechnical thermal properties of test

Ground-source heat pump systems,as the use of renewable heating,ventilating and air conditioning technology,with energy-saving,environmental protection and so on,are widely used around the world.Soil as a ground-source heat pump cooling and heating source,has a crucial impact on the entire system.Different load characteristics require system access,heat the soil differently,imbalance between soil temperature changes,affect the operation of the entire system.On the particular building soil thermal properties of ground source heat pump system testing is an important basis for the design of buried pipe system.Thermophysical testing the theoretical basis of this article to be a simple introduction and analysis of specific cases,come to the thermal conductivity of soil mass concrete thermal physical parameters such as,accurate design of ground source heat pump system provides a basis.
