摘要
由于地埋管系统的初调节性较差,目前地埋管系统的设计还是以同程式为主,可以确保系统水力平衡。本文以某一工程的设计入手,提出加大水平干管管径以减小不平衡率的异程式设计方案,并从初投资、运行费用以及节能等角度分析地埋管的水平干管同程式以及异程式设计的差异。最后得出结论并给出一个地埋管水平干管异程式设计的参考范围值。
As the poor initial regulation of the ground-source heat pump system, in order to ensure hydraulic balance,the design of the system is mainly with the reverse return mode now. Based on an engineering design, this paper puts forward a design scheme of direct return mode that increase pipe diameter to reduce the imbalance rate, and analyses the difference of reverse/direct return mode in ground-source heat pump system from first cost, operation cost and energy saving. Finally come to the conclusion and give a design reference range of the direct return mode in ground-source heat pump system.
