北京某大型商场空调系统节能改造方案分析

Energy-saving Transformation of Air Conditioning System in a Large Shopping Mall Located in Beijing

大型商场人流量大、散热设备多、空调系统运行时间长,有较大节能潜力。调研了北京某大型商场空调系统的能耗情况,针对其运行过程存在的问题,提出了一套基于空调系统节能控制技术的综合节能改造方案。研究表明,该空调系统节能改造后,年节电量为140.56万k Wh,每年节省电费160.24万元;节热量为601.82GJ,每年节省供热费用5.95万元,节能效果与经济效益较好,可为北京地区类似公建节能改造提供借鉴和参考。

Large shopping malls have large flow of people,more cooling equipment and long operation time of air conditioning system,which has great potential for energy saving.This paper investigated the energy consumption of air conditioning system in a Beijing's large shopping mall.Aiming at the problems existing in its operation process,a comprehensive energy-saving transformation scheme based on the energy-saving control technology of air conditioning system was proposed.The research shows that the annual energy saving of the air conditioning system is 1.41 million kWh,and the annual electricity saving reaches 1.60 million yuan.The heat saving is 601.82 GJ,and the annual heating cost saving reaches 59.5 thousand yuan.The energy saving effect and economic benefit are better than before the renovation,which can provide reference for similar public building energy saving renovation in Beijing area.
