区域级建筑土壤源热泵系统实际运行案例分析

Analysis on the actual operating case of ground source heat pump system for large-scale building

本文对一建筑规模为24.9万m2的区域级居住区建筑采用的土壤源热泵系统的实际运行状况进行调研测试,通过分析整个供暖季和制冷季地源侧和空调负荷侧的温度工况,得出地埋管循环水的温度变化特性,并针对本项目给出运行建议。

In this paper, a large scale ground source heat pump system which serves a residential zone with construction area of 249 thousand square meters was investigated and tested. The temperature variation characteristics of the circulating water in the ground heat exchanger were obtained through analysis of the temperature conditions of the whole heating season and the cooling season. Some operation suggestions were given for the case in this paper.
