Energy loss simulation of horizontal circuit header in ground-source heat pump systems in Beijing
摘要：
通过对竖直地埋管地源热泵系统的水平集管建立能量损失模型，分析了影响其能量损失的因素。以北京地区某办公建筑为例，模拟了地源热泵冬季运行过程中，水平集管能量损失对热泵机组COP的影响，从而得出不同水平集管长度相应的处理方法，为地源热泵系统设计的完善提供了参考依据。

Abstract：
Establishes the energy loss model for the horizontal circuit header in vertical ground heat exchanger systems, and analyses factor influencing its energy consumption. Taking an office building in Beijing as example, simulates the energy loss influence on the heat pump unit COP during the heating season. For different lengths of the horizontal circuit header, presents the corresponding treating methods which can be used as references for ground-source heat pump system design.
