进气冷却在微型燃气涡轮机CCP中的应用研究了冷热电联产系统，提出了利用冷热电联产系统产生的冷量对压缩机进气进行冷却的方法，可显著提高冷热电联产系统在高温天气下的性能，结果表明，进气冷却可以使微型燃气涡轮机的性能稳定在设计工况附近，进气冷却温度越高，微型燃气涡轮机的性能越稳定;环境温度越高，微型燃气涡轮机的性能越能得到有效的改善。显然，利用部分冷能冷却进气时，利用余热产生的冷能输出会减少。但是，当电驱动空调器用于通过使用多余的电力来补偿冷却能量输出时，系统的总冷却能量输出将增加。因此，在夏季高温环境下，进气冷却是提高微型燃气涡轮机冷循环系统性能的有效可行措施。
The application of inlet air cooling in the micro gas turbine CCP(combined cooling and power generation) system was studied.The method of cooling the inlet gas of compressor using the cooling energy generated by the CCP system was proposed which can notably improve the performance of the CCP system at high temperature weather,and an analyzing was done combined with a specific case.The results show that inlet air cooling can stabilize the performance of micro gas turbine operating around the design condition.The higher the ambient temperature is,the more effectively the performance of the micro gas turbine is improved.Apparently the cooling energy output generated by using the surplus heat will decrease when the partial cooling energy is used to cool the inlet air.However, the total cooling energy output of the system will increase when the electrically driven air conditioner is used to compensate the cooling energy output by using the excess electric power.In a word,inlet air cooling is an effective and feasible measure which can improve the performance of the micro gas turbine CCP system when environmental temperature is high in summer.
