To solve a problem wherein, in many cases, an energy saving means of an air conditioning system to fully open a flow control valve of a fan-coil unit cannot be adapted to an air conditioning facility such as existing hotel and hospital because flow control valve is not provided in each fan coil unit, and additional installation cost is required to mount new flow control valves.
In a method of controlling cold/warm water of an air conditioning system, rotational frequency of a rotational frequency control-type cold/warm water pump for sending cold/warm water, generated in a cold/warm water heat source machine, to a plurality of fan coil units etc. having ventilation amount control means is controlled based on the state of ventilation amount adjusted by each of the ventilation amount control means.
