办公楼中央空调节能措施的经济效益.doc

104 . 1. 法律事务部某办公楼中央空调节能措施的经济效益分析福建省第五建筑工程公司宋清弟摘要通过对具体工程实例分析和论述,得出中央空调的节能可以通过提高制冷主机冷凝器的换热效率来提高主机在常年运行时高效节能,并利用冷凝热回收技术来回收原来冷却塔带走的热量,这样既可得到免费热水,又可以减少冷却塔的排放热量,利用新风全热换热器来回收排风中的冷量,并通过空调自动控制系统,在中央空调各种不同工况时,进行优化控制,实现整个系统的节能运行,从而达到降低整个中央空调系统能耗的目的。关键词中央空调能耗;冷凝器清洗;冷凝热回收;全热回收;prehensive Building a Central Air · Conditioning Analysis of the Economic Benefits of Energy · Saving Measures Song Qing di Abstract Through specifc examples of projects and expositions that the central ai卜 conditioning refrigerat saving Can be achieved by improving the effi on energy he years to improve mainframe running high effi ciency and energy saving , and use condensing heat recovery technology to recoverthe original cooling tower heat away This not only receive fee hot water,co oling tower will reduce emissions of heat , wind · wide use ofthenewheatexchangertoheatrecovery hecentral air-conditoning in all kinds of dif er nt conditons ,, optimal control and realize the energy · saving operation oft he entire system , SO aS to achieve the central air- conditioning system to reduce energy consumpton purposes .
