以开机率表征变制冷剂流量多联机行为调节特性,对上海某办公建筑做了制冷制热共1年的数据调研.数据统计发现制热期间最大开机率仅为60%左右,制热能耗随开机率增大基本呈线性变化,统计区间样本数据能耗极差最大值为0.4左右.制冷能耗随开机率增大呈先缓后陡的指数变化增大趋势,对应极差最大值为0.55左右.使用数据包络分析法和Parzen窗法进一步分析了能耗随开机率的变化特性,研究结果表明,变制冷剂流量多联机系统在制热期间发生有效行为调节的概率为0.54,制冷期间发生有效行为调节的概率为0.44.
Based on the rate-of-performance characterization of the refrigerant flow control characteristics of multi-line regulation, a Shanghai office building made a refrigeration heating a total of 1 year of data research.Data statistics found that the maximum heating rate during heating is only about 60%, heating energy consumption The rate of increase of power-on rate basically changes linearly, and the maximum range of energy consumption of the sample data in the statistical range is about 0.4. The trend of cooling power consumption increases with the increase of power-on rate and then increases slowly, the corresponding maximum value is 0.55 .The results show that the probability of effective behavior regulation during the heating period is 0.54, and the probability of cooling during the cooling period The probability of valid behavior adjustment is 0.44.
