地埋管地源热泵系统水力工况分析

Analysis on hydraulic conditions of ground-source heat pump system

以检查井内分、集水器及其所连接环路为研究对象,分析了末端钻孔并联数、钻孔深度以及钻孔间距对管网系统水力特性的影响。通过所建立的水力模型,运用Matlab软件进行编程,计算了不同设计方案情况下地埋管系统的阻力损失。分析了不同类型地埋管管网的水力特性,给出了地埋管系统优化设计方法。

Taking the header inside inspection well and the circuit as the research object, analyses the influence of the number of parallel end drilling, drilling depth and drilling spacing on the hydraulic characteristics of the pipe network system. With the established hydraulic model and Matlab software, calculates the resistance loss of buried pipe system under the conditions of different design schemes. Analyses the hydraulic characteristics of different types of buried pipe network, and provides the optimization design method for the buried pipe system.
