摘要
介绍了美国建筑燃气内燃机与燃气轮机冷热电联产系统的应用现状。从变工况下的热电效率和火用效率两个方面比较了MW级燃气内燃机和燃气轮机冷热电联产系统的技术性能,分析了两者在不同冷热电需求下的一次能耗。对1～3MW建筑冷热电联产系统,燃气内燃机具有明显的节能和经济效益,而燃气轮机联合循环适用于规模更大的系统。
Application situation of gas engine and gas turbine CCHP systems applied in American buildings is presented. Based on thermoelectric and exergy efficiencies under variable operation conditions, technical performance of MW class gas engine and gas turbine CCHP systems is compared, and primary energy consumption of above two systems is analyzed under different demand for cooling, heat and power. It can be concluded that gas engine has more advantages in energy saving and economic benefits for 1~3 MW building CCHP system, and gas turbine combined cycle would be applicable for larger CCHP system.
