Abstract
A cogeneration system of the present invention includes: an electric power generator (); a cooling circuit () configured to cool the electric power generator () with a first heat transfer medium; a heat exchanger () provided on the cooling circuit (); an exhaust heat recovery circuit () through which a second heat transfer medium that exchanges heat with the first heat transfer medium via the heat exchanger () flows; a heat storage unit () connected to the exhaust heat recovery circuit () and configured to store the second heat transfer medium that has undergone a heat exchange by the heat exchanger (); and a controller (), wherein a first temperature sensor (), and a heater to which electric power is supplied from the electric power generator (), are connected, in this order, downstream of the heat exchanger () in a direction in which the second heat transfer medium flows, and the controller () controls a flow rate of a circulating pump () so that, based on a temperature detected by the first temperature sensor (), the detected temperature becomes a predetermined target temperature. In addition to preventing water temperature decrease in heat recovery and ensuring safety, this configuration can keep water temperature high at all times.
