气温影响空调负荷的累积效应导致能耗的分析

An Analysis of Energy Consumption Caused by Air Temperature-affected Accumulative Effect of the Air Conditioning Load

大中城市中,空调负荷消耗了大量电能,是电力负荷的重要组成部分。降低空调负荷是节约用电的重点方向,也是需求侧管理的重要方向。空调负荷对气温敏感,且存在明显的累积效应。文中分析了高温季节和低温季节累积效应的基本规律,建立了量化的累积效应后评估模型。通过分析没有累积效应时气温与负荷之间的关系,并与实际情况对比,获得累积效应所导致的电能消耗。对中国北方某市实际数据的分析表明,累积效应所导致的空调能耗巨大,是潜力巨大的节能方向。

In large cities, the air conditioning load is an important component of power load. The air conditioning load consumes large amounts of electrical energy. The reduction in the air conditioning load is not only the crucial direction of electricitysaving, but also an important direction of demand side management. The air conditioning load is sensitive to air temperature, and there obviously exists the accumulative effect. The accumulative effects of high temperature and low temperature seasons are studied. A mathematical model for quantitative post-assessment of the accumulative effect is proposed. By an analysis of the relationship between air temperature and power load on the days without accumulative effect and a comparison with the actual situation, the eleetrie energy consumption due to the accumulative effect can be obtained. The case study data on a city in North China shows that the energy consumption of air conditioning due to the accumulative effect is great, which is a tremendous potential direction of energy-saving.
