PROBLEM TO BE SOLVED: To provide a hot water storage heat accumulation control technology for a cogeneration system which allows the efficient storage of hot water in a small system for a household use or the like.SOLUTION: A hot water supply demand D(τi) and an exhaust heat recovery amount H(τi) in each time zone τi from a current time (t0) to n-hours after (tn) are predicted. Whether a heat accumulation amount Q(ti) in each time zone is balanced with the hot water supply demand D(τi) is determined in two stages by long-time prediction and short-time prediction. When a time zone in which the heat accumulation amount is insufficient exists in either of the prediction, the heating volume in an auxiliary water heater 5 is adjusted so that heat accumulation is completed before the starting time of the time zone. |
