PURPOSE:To prevent the remarkable change of feed water temperature by a method wherein the heat source equipment, to be stopped the operation thereof, is left in operating for a given period of time after the operation of the heat source equipment, whose operation is initiated newly, is begun upon switching the operations of the heat source equipments. CONSTITUTION:In case the operation of a refrigerator R1b is stopped and the operation of the refrigerator R2c is started newly, and in case of switching the operation, in which the refrigerator R2c is stopped and the refrigerator R1b is started newly, the refrigerator, whose operation is to be stopped, is left in operation for a given period of time t0 after the refrigerator, to be started newly, began the operation thereof. According to this method, the feed water temperature will not be changed remarkably by the feed water, supplied from the refrigerator operated until now, for a period of time, during which the feed water temperature, supplied from the refrigerator which began to operate newly, arrives at the predetermined value. |
