<p><P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of shortening rise time in a period of time from start of operation to rated operation of an engine even when temperature of the engine is low. <P>SOLUTION: This cogeneration system is provided with an exhaust heat recovery means for recovering exhaust heat of the engine 1 for driving a power generator 2 and an operation control means for controlling operation of each part. When a command for starting the engine 1 is given and temperature of the engine 1 is higher than reference temperature, the engine 1 is started, and then rated operation is performed immediately or after a short time elapses. When temperature of the engine 1 is lower than reference temperature, engine warming-up operation of heat medium heating type for heating a heat medium for cooling the engine while the engine 1 stops is performed until temperature of the engine 1 exceeds reference temperature. Next, the engine 1 is started, and then rated operation is performed immediately or after a short time elapses. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
