成都市不同年龄段居民用能行为的调查研究

Investigation on energy use behavior of residents of different age groups in Chengdu

首先,选取成都市居民为样本,并按不同年龄段划分为四组,即少年组、青年组、中年组和老年组;然后,详细调查了居民的室内热环境需求、热舒适的调节行为及用能模式;最后,交叉分析了不同年龄段居民用能行为,并采用SPSS中K-平均值聚类分析将用能行为划分成三级用能类型。研究结果表明:三类用能行为在空调使用时间、空调设定温度值上差别很大;通常,随年龄增加,居民的个体空调能耗值降低;少年组和青年组的"利己行为"将使家庭整体能耗值提高;中年组、老年组居民使用能耗值较低,对家庭整体能耗值影响较小。

Firstly, some residents in Chengdu city had been selected as the samples and divided into four groups according to their age, namely junior group, youth group, middle-aged group and elderly group. Then, their demand of indoor thermal environment, thermal comfort regulation behavior and energy use mode had been investigated in detail. Finally, their energy use behavior of different age groups had been cross-analyzed and classified into three levels by using K-mean clustering analysis method with SPSS. The results indicated that big differences existed among the three levels of energy use behavior in the service time and set temperature of air conditioner;and the energy consumption of individual air conditioning decreased with age;usually the individual air-conditioning energy consumption of residents decreased with the increase of age;"egoism" of junior group, youth group would made the total energy consumption of a family increase;the middle-aged and elderly residents used less energy and had less impact on the total energy consumption of a family.
