열병합발전 시스템의 운전조건에 따른 경제성 평가

The object of this study is to develop program for the optimal plants of the cogeneration systems composed of combining engine, generator, waste heat recovery exchanger, absorption chiller, boiler, etc. To perform the accurate simulation of the cogeneration system, it is first necessary to determine the energy demand categorized by electric power, heating, cooling and water supply. Then optimal operation modes is determined by economic assessment which is based on the efficiency of equipment and cost of fuel.
