<p>In a cogeneration apparatus (10) having a power generation unit (26) equipped with a power generator (20), an internal combustion engine (22), and a hot water tank (70) connected to the engine through a heat exchanger (30), there are provided a first pump (60) provided at a first flow channel (50) connecting the engine (22) to the heat exchanger (30) and a second pump (66) provided at a second flow channel (54) connecting the heat exchanger (30) to the hot water tank (70). A temperature of the engine cooling water heated by the engine (T1) and a temperature difference (”T) between the temperature (T1) and a temperature of the engine cooling water cooled by the heat exchanger (T2) is determined and based on the determined values, flow rates of the first and second pumps are controlled.</p> |
