分布式功能系统是指在用户端或靠近用户现场独立输出电热(冷)能的系统,该系统既能发电,又能利用余热制冷、供暖、供应热水,使用的能源包括天然气、沼气及可再生能源等清洁能源。近年来,分布式功能系统迅速发展,不少发达国家积极推动,主要用于工业园区、公共设施和住宅等领域。我国积极鼓励这种供能方式,上海自2004年起开始推动发展,主要针对以天然气、沼气等为燃料的小型供能系统(单机1万千瓦以下),出台了支持
Distributed functional system refers to a system that independently outputs electric (cold) energy at the user’s site or near the user’s site. The system can generate electricity and utilize waste heat to cool, heat and supply hot water. The used energy sources include natural gas, biogas, Renewable energy and other clean energy. In recent years, the rapid development of distributed functional systems, many developed countries to actively promote, mainly for industrial parks, public facilities and residential areas. China has actively encouraged this mode of energy supply. Since 2004, Shanghai has started to promote the development of small-scale energy-supply systems (single power plants with a capacity of 10,000 kilowatts or less) that are mainly powered by natural gas and biogas,
