| Abstract: | 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. |
