某高校教学楼空调系统运行能耗数据分析

Energy Consumption Data of Air Conditioning System--Take One University Teaching Building for Analysis

本文以能效比EER为依据,基于某高校教学楼空调系统的监测平台的历史能耗数据,分析比对了两学年的空调系统运行情况,当教室同时使用率大于0.68,系统末端能耗对能效比产生较大影响。降低末端能耗的前提是满足教室实际耗冷量,通过极大似然估计法估算出不同教室单位面积每小时所需冷量范围,得出其分别在124.2~148.96 W/m^(2)、52.5~96.26 W/m^(2),为后期制定空调系统运行阶段的节能策略提供一定参考。

Based on the energy efficiency ratio(EER)and the historical energy consumption data stored by the monitoring plaform,attached to the air conditioning system of one university teaching building,this paper analyzed and compared the operation of the air conditioning system in two academic years,when the simultaneous utilization rate of the classroom is greater than 0.68,the energy consumption at the end of the system has a greater impact on the energy efficiency ratio.The premise of reducing the end energy consumption is to meet the actual cooling consumption of the classroom.The required cooling capacity per hour per unit area of diverse classrooms are estimated by the maximum likelihood estimation method,the results are 124.2~148.96 W/m^(2) and 52.5~96.26 W/m^(2) respectively.It provides some reference for formulating energy-saving strategy of air conditioning system in operation stage.
