摘要
介绍了冷热电联供(CCHP)系统,以上海某示范性微燃机冷热电联供系统为研究对象,通过建立系统主要设备的数学模型,模拟分析了系统在不同环境温度下的性能和系统全年的运行工况。结果表明:微燃机冷热电联供系统的性能受环境温度的影响,系统过渡季节不运行时年平均能源综合利用率可达到70%以上。
Firstly,combined cooling heating and power（CCHP）systems are introduced.The mathematical model of main components is built in order to study the micro CCHP system in Shanghai Company.Based on the mode,the operating performances of the system under different ambient temperature are simulated.The operating performance of this system throughout the year is further simulated based on the previous conclusion.The results show that the environmental effects on the CCHP system performance.When the system does not run during the transitional seasons,the average overall energy efficiency of a year is more than 70%.
