摘　　要：随着近年来气候变化,全球制冷能耗占比增长,建筑空调系统的节能减排成为了低碳发展的重要工作之一。建筑空调室内设定温度对空调系统能耗影响大,适宜的空调设定温度操作可以有效降低系统能耗。因此,本研究基于多联机大数据集中24.7万次空调制冷过程运行数据,分析提取了空调“设定温度”操作模式特征,利用特征指标将不同空调“设定温度”操作模式的用户进行分类和大数据统计分析,发现习惯于设置低空调“设定温度”实现快速降温并在达到热舒适需求后主动关闭空调的操作模式类型A用户占比61.5%,而设置空调“设定温度”依靠室内机自动控制使得室内温度达到“设定温度”的操作模式类型B用户占比38.5%,并且所有用户中占比54.3%的单次开启时长小于5.4 h类型A用户是多联机空调室内机的最主要操作模式。本研究也对空调室内机室内环境温度控制逻辑优化策略展开了探讨。With climate change in recent years,the share of cooling energy consumption has grown across the world,and energy saving and emission reduction in building air conditioning systems have become one of the important tasks of low carbon development.The indoor set temperature of building air conditioning has a major impact on the energy consumption of air conditioning systems,and appropriate air conditioning set temperature operation can effectively reduce system energy consumption.To this end,based on the data of 247,000 air conditioning operations in the VRF big data set,this study analyzed and extracted the characteristics of the air conditioning "set temperature" operation mode,and used the characteristic indexes to classify users with different air conditioning "set temperature" operation modes and to realize big data statistical analysis.The results show that 61.5% of users,A-level users,are accustomed to setting a low "set temperature" to achieve rapid cooling and actively turn off the air conditioner after reaching the thermal comfort demand,while 38.5% of users,B-level users,use the indoor automatic control unit to achieve the "set temperature".Type A users,who turn on the air conditioner for less than 5.4 hours at a time,account for 54.3% of all users.This study also explored strategies for optimizing the indoor ambient temperature control logic of air conditioning indoor units.
