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。
It is considered that the current energy-saving evaluation system can not evaluate the centralized air-conditioning system in a comprehensive and correct manner by using the total electricity consumption in year and air-conditioning and the power consumption per unit air-conditioning area. A new automatic tracking and evaluation system for energy efficiency of central air conditioning is proposed. The system measures real-time cooling capacity of central air conditioning system, real-time power consumption of each air conditioning system, real-time power consumption, real-time energy efficiency, historical average comprehensive energy efficiency, Average load rate and other data tracking, monitoring, statistics and display. Illustrate the application of new evaluation system with engineering examples.
