PURPOSE:To permit to reduce fluctuation of heat accumulating amount and effect economical heat accumulating operation by a method wherein a plurality of heat accumulating operation modes are determined in accordance with the conditions of heat accumulating operations and objective heat accumulating amounts are determined for respective heat accumulating operation modes while the heat accumulating operation is controlled so that the heat accumulating amount becomes the objective heat accumulating amount upon finishing each heat accumulating operation mode. CONSTITUTION:A plurality of heat accumulating operation modes (hereinafter described by operation mode) M1-M4, M0 are determined in accordance with the conditions of heat accumulating operations while objective heat accumulating amounts Ee1-Ee4, Ee0 are determined for respective operation modes M1-M4, M0. Upon starting respective operation modes, a load rate is obtained on the basis of the ratio of a difference between the objective heat accumulating amount Ee1-Ee4, Ee0 and present heat accumulating amount E to a time from starting to finishing of the modes M1-M4, M0 and the number of simultaneously operated heat source equipments is determined in accordance with the load rate. The heat accumulating operation is controlled so that the heat accumulating amount E of respective operation modes becomes the objective heat accumulating amount Ee1-Ee4, Ee0. According to this method, the optimum number of sets of heat source equipments are operated at all times and excessive change of heat accumulating amount due to operating the number of sets of heat source equipments, which are more than necessary sets, may be precluded. |
