Claim:
A method for controlling a cogeneration system, comprising: a first step of receiving an operation ON signal for an air conditioner; a second step of, following the first step, determining whether or not a power load of the air conditioner corresponds to a generator driving load requiring driving of a generator; a third step of, if it is determined at the second step that the power load corresponds to the generator driving load, rotating a radiating fan, switching a flow rate control valve to a radiating mode, driving a heat medium circulation pump, and driving a drive source adapted to drive the generator; a fourth step of, following the third step, checking an electric power generation state of the generator; a fifth step of, if it is determined at the fourth step that the generator operates normally, switching electric power supplied to the air conditioner from commercial electric power to electric power generated from the generator; and a sixth step of, following the fifth step, operating the air conditioner.
