我国北方城镇实行的集中供热,为改善人民生活和推动城市的经济建设做出了巨大贡献,符合国家低碳发展的要求,有利于环境保护。实施过程中,普遍存在供热企业供热成本偏高、运行效率偏低、能耗过大等问题。其中理论数据和供热系统不匹配、热力设计和供热运行相互脱节,缺乏一套符合当地实际情况和供热企业现状的具体节能降耗途经和措施等则是问题的关键。
The centralized heat supply in cities and towns in northern China has made great contributions to improving the people’s lives and promoting the economic development of the city. It is in line with the requirements of the country’s low-carbon development and is conducive to environmental protection. During the implementation process, there are widespread problems in heating companies such as high heating costs, low operating efficiency, and excessive energy consumption. The theoretical data and heating system mismatch, thermal design and heating operation are out of touch with each other. The lack of a set of specific energy conservation and consumption reduction methods and measures that are in line with the local actual conditions and the status of heating companies is the key to the problem.
