摘　　要：通过与燃气、燃煤分产系统的对比分析,得出天然气分布式能源的节能特性:在供热工况下,相对燃气分产系统,分布式能源系统节能效果高达40%;在制冷工况下,只有在发电效率和制冷效率较高时才会节能,且节能效果一般不超过10%;与燃煤分产系统相比,在供热工况下,分布式能源系统节能效果高达50%;在制冷工况下,节能效果一般在10%以上。因此,要正确看待天然气分布式能源系统的节能性,根据对象负荷要求,合理应用分布式能源系统。According to comparison w ith the coal-fired generation system and the gas-fired generation system,it proves that natural gas distributed energy system may save more energy and reduce more pollutant emission. Comparing w ith the gas-fired generation system,in heating conditions,distributed energy system has significantly saving effect,usually up to 40%. In cooling conditions,only at higher pow er generation efficiency and cooling efficiency,energy w ill be saving and energy-saving effect is generally not more than 10 %. Comparing w ith the coal-fired generation system,in heating conditions,distributed energy system has significantly saving effect,usually up to 50%. In cooling conditions,the energy-saving effect is generally more than 10 %.Therefore,to correctly view energy efficiency of natural gas distributed energy system is very important for its development.
