通过埋管分区运行实现土壤热平衡
Discussion on keeping the soil heat balance by zone piping and partition running
摘要:
结合实际工程案例,介绍了在地埋管地源热泵系统达到基本热平衡的前提下,通过分区配管和分区运行尽可能达到土壤热平衡的思路。将埋管区分为外区、中区和内区。详细对比了新旧埋管分区的运行策略,并分析了优势和劣势。结果表明,在机组大部分运行区间内采用分区配管、分区运行,节能效果良好。

Abstract:
With an actual project case, presents the thought of keeping the soil heat balance by zone piping and partition running as far as possible on the premise that the heat charging and discharging quantities are basically balanced. The buried pipe region is divided into three parts, i.e. inner area, middle area and outer area. Compares the operation strategies of traditional and new zoning methods in detail, and analyses the advantages and disadvantages. The results show that the strategy with zone piping and partition running in most area can create a sound energy-saving effect.
