冷凝热回收技术在热泵系统中的应用研究

The Study of Condensing Heat Recovery Technology in the Application of Heat Pump System

空调系统和生活热水系统独立设计可满足室内人员对空调和生活热水的同步需求,而其系统独立性却成为建筑物能耗较高的重要原因之一。以泾阳县医院综合门诊楼热泵系统为例,利用建筑热环境设计模拟分析软件DeST得到全年冷热动态负荷,依据设计规范计算生活热水负荷,引入经验系数确定该热泵机组所能提供的逐时冷凝热负荷,将冷凝热负荷与生活热水负荷对比。结果表明,在夏季空调季利用冷凝热回收技术可以完全满足7月份、8月份生活热水需求,虽然6月份、9月份无法全部满足,但可有效减少辅助加热设备的用量。

Constructions all have demands for air conditioning and living hot water.Currently,the cold and heat source program for building is to design air conditioning systems and living hot water systems separately.This study aims to simulate the hourly air conditioning cold and hot load of the water source heat pump system in a complex building of Jingyang hospital by using DeST,an energy simulation software.The living hot water load of the building is calculated in detail.Condensing heat provide by the original water source heat pump units is calculated.The result shows that,using condensing heat recovery technology of recycling heat can basically meet the demand of hot water,a few months cannot meet the demand of hot water,but can reduce the dosage of the heating equipment.
