PURPOSE:To quickly evaluate the energy saving and economical efficiencies of a cogeneration system at the time of operation. CONSTITUTION:The purchasing electric energy, generated electric energy, thermally utilized energy, engine fuel consumption and boiler fuel consumption of the cogeneration system are detected by detectors 1 to 5, respectively, and inputted to a calculator 18 via signal converters 6 to 10, and reference energy and consumption energy are calculated by means of calculation coefficients (engine fuel calorific power, boiler fuel calorific power) set in setters 13 and 15 for each cogeneration system and the energy saving efficiency is calculated and, displayed on an energy saving efficiency display device 19. The calculation coefficients (purchasing unit rice, engine fuel unit price, boiler fuel unit price) set in the respective setters 11, 12 and 14 are inputted to the calculator 18 to calculate a reference cost and therefore, the economical efficiency is calculated and displayed on an economical efficiency display device 20. |
