<P>PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system enabling a stable operation by reducing the flow rate of cooling water flowing into a cooling tower as much as possible and at the same time, by keeping the temperature of cooling water flowing into an exhaust heat source at a desired value. <P>SOLUTION: The system includes a heat source water outgoing pipe branched from a cooling water return pipe 15 configured to guide the cooling water after having cooled a condenser 3 to a cooling tower 7, a heat pump 5 configured to output heat by recovering heat from the heat source water guided by the heat source water outgoing pipe, a heat source water return pipe 33 configured to join the heat source water after the heat of which is recovered by the heat pump 5 with a cooling water outgoing pipe 13, and a control part 25 configured to control activation and deactivation or the number of rotations of a fan 17 provided in the cooling tower 7, wherein the control part 25 controls the fan 17 so that the heat source water joins from the heat source water return pipe 33 and the temperature of the cooling water at the inlet flowing into the condenser 3 is a desired value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
