关于完善公共建筑集中空调系统节能评价体系的一些探讨

认为目前的节能评价体系用"年空调总用电量"、"单位空调面积耗电量"不能全面、正确地评价集中空调系统。提出了新的集中空调能效自动跟踪评价系统,该系统对集中空调系统的实时制冷量、各空调用电设备的实时功率、实时用电量、实时能效、历史平均综合能效、实时负荷率、历史平均负荷率等数据进行跟踪、监测、统计并显示。以工程实例说明新的评价系统的应用。

Improvement of energy efficiency evaluating system for central air conditioning system in public buildings

Points out that the current energy efficiency evaluating system using the indices like total annual electricity consumption for air conditioning and electricity consumption per unit area for air conditioning cannot provide a full and correct evaluation of a central air conditioning system.Puts forward a new evaluating and tracking system,which can track,monitor,count and display real-time refrigerating output,real-time power,real-time electricity consumption,real-time energy efficiency,average historical integrated energy efficiency,real-time load ratio,average historical load ratio,etc.Provides some examples to illustrate the application of the new evaluating system.
