地源热泵系统热平衡分析及其在大型公共建筑中的应用

摘要

热平衡是影响土壤源热泵系统持久稳定运行至关重要的因素之一。本文阐述了热失衡产生的原因、国内常见情况与解决办法，提出了在大型公共建筑中应用复合式冷却塔耦合地源热泵系统解决冷热不平衡问题。研究结果对解决类似工程项目的热平衡问题具有参考意义。%Thermal balance is one of the critical factors that impact the stable and long term operation of ground source heat pump systems. The reasons, common cases and solutions of the underground thermal imbalance in China are introduced. The hybrid ground source heat pump with cooling tower is adopted to solve the problems of thermal balance in large scale public buildings. The result offers a reference to solve the problems of thermal imbalance in similar engineering project.
