竖直U形地埋管换热器优化设计

摘要

以地埋管地源热泵系统模型为基础,引入竖直U形地埋管换热器的DST模型,将钻孔深度、钻孔间距和钻孔数量作为热泵系统的设计优化变量,通过全寿命周期内的系统运行模拟,提出了确定热泵系统换热器组群最优组合形式的方法.为地埋管地源热泵系统的方案优选和运行策略的评估提供了必要的理论依据.%Based on the ground source heat pump system model, establishes the duct storage system (DST) model of the vertical U-tubes ground heat exchanger, in which the depth, distance and number of boreholes are treated as optimization variables, through the operating simulation in its life cycle, provides the optimal methods and it gives references for plan optimization and operating strategy evaluation of the ground source heat pump system.
