PROBLEM TO BE SOLVED: To provide the control system of an apparatus utilizing water as a heat exchanging medium accurately predicting demands at various parts of a building in advance of use or at any time band. SOLUTION: A control system for feeding conditioned water to a plurality of heat exchangers (18, 20 and 22) includes a system controller (44) collecting data related to current and future demands by a plurality of zone controllers (24, 30 and 34) related to a plurality of the heat exchangers. The system controller can be operated to feed the conditioned water to these heat exchangers in case that the current demand of the conditioned water is not enough for feeding the conditioned water to the heat exchangers. The system controller analyzes the current demand of the conditioned water together with the predicted demand, and executes the operation of feeding conditioned water by deciding whether the combination of these demands exceeds the minimum level or the required number necessary for permitting the feeding of the conditioned water to the heat exchangers. |
