微燃轮 冷热电联供系统 分析
利用分析法对由微型燃气轮机、余热补燃型吸收式制冷机和余热锅炉组成冷热电联供系统进行了分析.以某用能建筑为例,分析得出了不同季节和联供系统子系统的损失和效率.夏季时,吸收式制冷机的损失最大,效率有很大的提高空间;在不用季节,余热锅炉的损失也较大,应作为主要的改进设备.通过效率分析,为联供系统的能质改进提供了一定的参考.%In the paper,micro-turbine cooling heating and power(CCHP)system were analyzed using exergy analysismethod. The CCHP system was constituted of micro-turbine,exhaust and direct-fired reffigeration unit and wasteheat boiler. A building using cooling heating and power was selected,whose exergy loss and exergy efficiency ofdifferent season and subsystem were gotten. The result shown that exergy loss of reffigeration unit was the biggestand there was more improved space for reffigeration unit. Exergy loss of waste heat boiler was big in every seasonand it should be improved. Some references may be provided for improvement of energy quality of CCHP systemaccording to the exergy analysis.
