八四年底,北京节能技术服务中心与核工业部第二研究设计院一起,选择了十个年耗煤量万吨以上,并且做过热平衡测试的企业进行能源使用的调查。这些企业在能源管理和组织领导方面是北京市较好的单位,其中几家还是全国同行业的先进单位。因此,它们的供热系统的各项指标是比较先进的。通过调查发现,即使在这些企业中,在能源的利用方面仍然存在不少问题,节能的潜力还很大。 At the end of August of 1994, Beijing Energy Saving Technology Service Center and the Second Research and Design Institute of the Nuclear Industry Ministry together selected ten companies that had consumed more than 10,000 tons of coal and conducted heat balance testing to conduct energy use surveys. These enterprises are better units in Beijing in terms of energy management and organizational leadership, and several of them are advanced units in the same industry in the country. Therefore, the indicators of their heating systems are relatively advanced. Through the investigation, it is found that even in these enterprises, there are still many problems in the use of energy, and the potential for energy saving is still great.
