经济增长和节能的若干宏观指标 总被引:3,自引:0,他引:3
<正> 1.前言在我们作宏观能源经济分析时,比较容易得到的基本数据是有关经济增长的数据(如各种产值或产值指数)、产品生产量和能源消耗的数据(如能源消耗量或其相对指数)。根据研究工作的需要,有时需要利用上述基本数据进行逐年的分析计算,计算诸如经济增长率、能源消耗增长率、能源供应增量,能源单耗、节能量、节能率、能源消耗弹性系数等宏观指标,以便分析逐年的具体问题;而在另一些研究任务中,我们希望对一个历史时期的能源经济现象作宏观规律 相似文献

The energy consumption of campus buildings has specific characteristics, because of the concentrated distribution of people’s working time and locations that change in line with distinct seasonal features. The traditional energy system design and operation for campus buildings is only based on the constant room temperature, such as 25°C in summer and 18°C in winter in China, not taking into consideration the real heating or cooling load characteristics of campus buildings with different functions during the whole day and whole year, which usually results in a lot of energy waste. This paper proposes to set different set-point temperatures in different operation stages of public and residential campus buildings to reduce the heating and cooling design load for energy station and total campus energy consumption for annual operation. Taking a campus under construction in Tianjin, China as an example, two kinds of single building models were established as the typical public building and residential building models on the campus. Besides, the models were simulated at both set-point room temperature and constant room temperature respectively. The comparison of the simulation results showed that the single building energy saving method of the peak load clipping could be used for further analysis of the annual energy consumption of campus building groups. The results proved that the strategy of set-point temperature optimization could efficiently reduce the design load and energy consumption of campus building groups. 相似文献
