区域供热被视为中国国家能源战略中节能行动的关键要素，而中国目前的空间供热仍以燃煤锅炉为主。然而，目前还没有定量的研究来分析中国未来的热战略。因此，制定降低能源消耗和碳排放的发展战略至关重要。在本文中，以下三个热策略进行了模拟与能源建模工具EnergyMonitoring：当前的热策略，一个单独的热策略和一个新的区域供热策略。从国家能源系统的角度进行比较。三种策略的比较表明，引入工业和发电厂余热的新型区域供热策略比单独供热策略和现行供热策略在经济和技术上更优。结果表明，区域供热可以减少约60%的建筑供暖的能源消耗，降低15%的供热成本相比，目前，实施的热策略。
District heating is regarded as a key element of energy saving actions in the Chinese national energy strategy, while space heating in China is currently still dominated by coal boilers. However, there is no existing quantitative study to analyse the future heat strategy for China. Therefore, it is critical to formulate a development strategy to decrease energy consumption and carbon emissions. In this paper, the following three heat strategies are simulated with the energy modelling tool EnergyPLAN: the current heat strategy, an individual heat strategy and a new district heating strategy. These are compared to each other from the national energy system perspective. The comparison of the three strategies indicates that the new district heating strategy which introduces surplus heat from industry and generation plants is more economically and technically optimal than the individual heat strategy and the current heat strategy. The results show that district heating could contribute to a decrease in energy consumption for building heating by about 60% with 15% lower heating cost compared with the current, implemented heat strategy.
