<p><P>PROBLEM TO BE SOLVED: To provide a calculation method for a cogeneration system capable of easily calculating numerical data such as energy rate cut with a simple structure. <P>SOLUTION: The energy amount of a fuel gas 2 used in a fuel cell unit 10 is determined from the regulation level of a gas regulating valve 17, and a first gas rate C1 and a first carbon dioxide emission amount G1 corresponding to the energy amount are calculated. The output electric energy and output heating value generated in the fuel cell unit are measured, and an electric rate C2 and a second carbon dioxide emission amount G2 for obtaining the output electric power are measured and calculated by an electric control device 16, and a second gas rate C3 and a third carbon dioxide emission amount G3 for obtaining the output heating value are calculated from the temperature of a heat medium entering and leaving a hot water storage device 20 by use of temperature sensors 18A and 18B. The first gas rate C1 and the first carbon dioxide emission amount G1 are subtracted from the electric rate C2, the second gas rate C3 and the second and third carbon gas emission amounts G2 and G3. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
