摘　　要：分析了全球气候变化和能源转型的形势。指出大规模利用可再生能源和实现城市供暖和交通的电气化,应该成为新冠疫情之后全球经济复苏的重要选项。能源总线系统(第5代区域供热供冷系统)的概念来源于地源热泵(GSHP)系统和水环热泵系统,通过暖管和冷管为分布式水源热泵提供热源和热汇,可以利用低品位可再生热源和废热余热资源提高系统效率,利用不同用途的建筑物之间的能源协同实现热回收。分析了能源总线应用中几项关键技术,提出了需要研究的几项重要技术。指出能源总线可以做到比传统系统更高的能效和更好的经济效益,可以作为疫情之后促进消费、拉动投资、改善民生的一项措施。Analyses the situation of global climate change and energy transition.Points out that largescale use of renewable energy and the electrification of urban heating and transportation should become one of the important options for global economic recovery after the COVID-19 epidemic.The concept of energy bus system(5th generation district heating and cooling system)is derived from the ground-source heat pump(GSHP)system and the water loop heat pump system.which provides heat source and sink for distributed water-source heat pumps through a warm pipe and a cold pipe.Various low-grade renewable heat sources and waste heat resources can be used to improve system efficiency,and heat recovery can be achieved by utilizing energy synergy among buildings of different purposes.Analyses several key technologies in the application of energy bus and proposes several important technologies that need to be studied.Indicates that the energy bus can achieve higher energy efficiency and better economic benefits than traditional systems,and can be used as a measure to promote consumptiostimulate investment,and improve people's livelihood after the COVID-19 epidemic.
