一、耗热指标 耗热指标是供热设计的重要参数,它是确定热源能力,规划供热面积和计算经济效益的主要依据。然而由于用户类别不同,因而不同类别的建筑物耗热指标也不同,住宅办公、学校、工厂、宾馆等均需分别选用不同的耗热指标。 长春市供热工程选用的耗热指标见下表 1。 上述耗热指标是室外采暖设计温度为:-23℃时的耗热指标,该指标是参照吉林省建筑物耗热指标及国内现有供热工程实际运行选用的耗热指标经综合分析确定的。
I. Heat Consumption Index The heat consumption index is an important parameter for heat supply design. It is the main basis for determining the heat source capacity, planning the heating area and calculating the economic benefits. However, due to the different types of users, different types of buildings have different heat consumption targets. Different heat consumption indicators are required for residential offices, schools, factories, and hotels. The heat consumption indicators selected for the heating project in Changchun City are shown in Table 1 below. The above heat consumption index is the heat consumption index when the outdoor heating design temperature is: -23°C. The index is determined by comprehensive analysis with reference to the heat consumption index of the building in Jilin Province and the heat consumption index of the actual operation of the existing domestic heating project.
