Application of combined cooling heating and power system to office buildings

Simulates annual loads of office buildings in Shanghai by means of EnergyPlus. Analyses the characteristics of load changes in a whole year. Obtains the ratio of heat and cool load in office buildings in Shanghai and the change of hourly load proportion. Combing electric load data in Japan, works out the hourly heat-to-electric ratio of office buildings in typical month in Shanghai. Compares the economic effects of different systems, which provides references for the selection of combined cooling heating and power system.
