摘要
通过对空调能耗的组成分析,指出空调系统辅助设备(风机、水泵)的能耗在空调节能中占有重要地位,以变水量空调水系统为分析对象,说明变水量技术的成功应用来源于节能的需求与技术的发展,分析了空调水系统采用变频技术后对水系统的水力工况、系统能耗、设备降温除湿能力的影响,最后就作者在工程中碰到的一些典型案例作简单分析,指出变水量系统的设计与改造原则应该立足于建筑空调负荷的全年变化特征,必须结合水泵特征和水系统阻力特征进行具体分析,避免节能技术应用中的鱼目混珠现象。
Based upon the analysis of the building air-conditioning energy use, the variable water volume（VWV） systems are taken as the discussed object. Its effect on the water system hydraulic operation state, total system energy consumption and equipments＇ dehumidification capacity is analyzed, And some typical engineering samples are studied to point out that the designing and reconstruction of VWV system should based on the complete understanding of the characteristics of building annual air-conditioning load, water system hydraulic operation state and pumps＇ operation state.
