摘要
采用冷却塔补偿来减少夏季土壤排热量的做法是地埋管地源热泵最常见的一种热平衡措施,但目前与其相适应的控制策略尚不够完善.在此,针对采用冷却塔补偿的地埋管地源热泵热平衡系统,提出一种以效率优先和热量补偿双模式运行的控制策略.这种控制策略明确了冷却塔与地埋管双向切换的条件,可以在保持地埋管地下热平衡前提下提高地源热泵系统的工作效率,并能够自动适应不同负荷特点的建筑物.
Abstract
Using cooling tower to reduce soil heat in summer is one of the most common heat balance measures for ground source heat pumps,but the corresponding control strategy is not perfect.In this paper,for the heat balance system of ground source heat pump with cooling tower compensation,a dual-mode operation control strategy with efficiency priority and heat compensation is proposed.This control strategy defines the conditions of bidirectional switching between the cooling tower and the buried pipe,which can improve the working efficiency of the ground source heat pump system on the premise of maintaining the underground heat balance of the buried pipe,and can automatically adapt to buildings with different load characteristics.
