COGENERATION SYSTEM AND OPERATING METHOD OF COGENERATION SYSTEM

摘要

A cogeneration system according to the present invention includes a power generator (2), a first circulation passage (3), a first heat medium circulator (4), a first heater (5), a first temperature detector (7), a first tank (10), a first valve (11A, 11B), and a controller (16). The first heat medium circulator (4) is configured to cause a first heat medium to flow from the first heater (5) toward the first temperature detector (7). The controller (16) performs a first heating operation of heating the first heat medium by the first heater (5) and activating the first heat medium circulator (4). In a case where a temperature detected by the first temperature detector (7) after the first heating operation is lower than a preset first predetermined temperature or in a case where a temperature difference between the temperatures detected by the first temperature detector (7) before and after the first heating operation is a temperature change smaller than a preset first temperature difference, the controller (16) determines that the cogeneration system is abnormal.
