摘要
公共建筑中的空调冷凝机组的散热能力在夏季受高温影响,其运行能力远低于设计要求,而依托于城市公共建设中的高层建筑物的特性,将雨水进行有效地收集,作为冷却水给空调室外冷凝器喷淋降温,进行辅助冷却,可以达到增加制冷系统的产冷量、提高空调的节能效率的目的。由于雨水在进入喷淋系统前已经经过相应的过滤装置,故其多余的雨水储备还可以再进行第二次利用,即提供洗车、喷灌浇花等系统用水。以重庆市某一公共建筑为例,对其进行设计改造,节水的综合节能效率平均可达30%。在雨水充沛地区,该效率数值还会随着建筑物规模的扩大而增加,这将十分契合当下社会发展进程中对建筑物的大量需求。
At present because of the influence of high temperature on the radiating capacity of air conditioning condensing units of the public buildings in the summer,its ability to run is far less than the design requirements.However,relying on the characteristics of urban public construction of high-rise buildings,by collecting the rainwater effectively,as the cooling water contributing to the decrease of temperature of air conditioning outdoor condenser through spray cooling,auxiliary cooling can increase the refrigeration system of the refrigerating capacity and improve the energy efficiency of air conditioning.Because of the rain before entering the spray system has passed across the appropriate filtering device,so the excessive storage of rainwater can also be used for the second use,that is,to provide water for washing,irrigation for flowers and so on.We take a public building in Chongqing city as an example,by transforming its design,comprehensive energy saving efficiency can reach about 30%.In the area of abundant rainfall,the efficiency value will increase with the expansion of the scale of buildings,which will fit in the current social development process of building a large number of demands.
