中央空调水系统变频节能改造分析与实践

摘要

空调水系统是空调系统中的重要组成部分,其运行电耗大.从节能角度分析了水系统变频的工作原理,比较了水系统工频和变频的优缺点,并介绍了节能改造工程的控制原理.同时结合具体的改造工程,分析了水系统的节能效益.结果表明,改造后的空调系统运行正常,室内温度和湿度均满足要求,节能效果显著.%Water system is one of the significant compositions with large power consumption in air-conditioning equipment. From viewpoint of energy-saving, the variable frequency operational principle of the water system is analyzed, the merits and demerits of operating water system under power frequency or variable frequency are compared, and the control principle of the energy-saving revamping project is introduced. In addition, combining with the specific project, the benefit of energy-saving for the water system is analyzed. The result shows that after revamping, the air-conditioning system runs properly, both the indoor temperature and humidity meet the specifications; the revamping technology offers significant energy-saving effects.
