摘要
随着科技的进步和人们生活水平的提高,能源消耗逐年增加,进而使得建筑节能问题在国内外备受关注。本次居民用电能耗调查的目的是了解大连市居住建筑的真实耗电情况,同时找到其用电规律,并提出有效的节能运行管理建议。本文一方面通过对大连市6处具有代表性的居民小区两年来的用电量进行持续的记录、统计、分析与比较,另一方面,通过调查问卷的方式了解了居民的整体用电习惯和特点,同时结合大连市的气候特征等多方面的因素,得到了大连市的用电能耗规律,大体上描述了该地区的附加采暖、空调能耗。另外通过对该地区居民用电规律的分析预测了未来几年的用电趋势变化情况,同时分析了目前的节能潜力,进而提出了相应的节能节电方案。
Along with the improvement of scientific technology and living standard of average people, energy consumption increases year by year, which result in much more attention paid by scholars all over the world towards energy saving. The purpose of this investigation is to analyze the regular pattern of power consumption of residents in Dalian city and proposes effective saving suggestions about power management and operation. The conclusion is based on both the data of power consumption collected in the past three years at six typical residential areas in Dalian, as well as the large quantity of field questionnaires and interviews related to the daily customs about using electrical appliances of corresponding residents, especially in the period of summer and winter. Besides, by comparing the different value of power consumption in the same place but different months and analyzing the causation of these power consumption characteristics, this paper stresses on the definition and calculation of basic power consumption and additional power consumption, hence summarizes the overall situation of additional energy-consuming for providing heating loads and refrigerating loads within Dalian area. At the same time, the correlative factors of the amount of power consumption are depicted. Finally, depending on the power consumption trends in the past three years （both the average power consumption and the maximum one）, this paper also depicts an annual unit change curve and gives the prediction of the power consumption in Dalian area in a few years. According to the conclusion, the power consumption of residents in this area will keep rising gradually in the coming few years until reaches a stable point,which is the result of both the electricity law and the needs of the community. Additionally, there are still much more efforts that our society need to improve to save energy. At the end of this paper, several suggestions of the energy saving are brought forward.
