According to the information of a large-scale public building in Shanghai, annual hourly loads of cooling, heating and power are calculated separately on the basis of Hourly Load Apportionment Ratio Method. Based on load characteristics and local practical condition, three cases are proposed for further comparison and selection by PRUE, ESR, CRR and PBP, and then the optimal case is to be determined. Moreover, the impact of installed capacity and gas price on the effect of applying CCHP system would be discussed. The result shows that both hotel and office area are appropriate for utilizing CCHP system; the combination of electro-refrigerator and absorption refrigerator is more economically preferable; PBP increases at first and then decreases while the capacity of electric generator rises, and when the capacity of generator and refrigerator are 4000 kW and 4500 RT, the PBP is lowest; The PBP will be 3 to 5 years if the price of natural gas could be fixed between 2.5 Yuan/m~3 and 3 Yuan/m~3, which is a remarkable indicator of economical efficiency.
