Air conditioning control device

In an air conditioning system including at least one or more first air conditioners performing a latent heat treatment of air containing outside air for each indoor space controlled to be air conditioned, at least one or more second air conditioner performing a sensible heat treatment of mixed air obtained by mixing air processed after the latent heat treatment with return air from the indoor space, a first air conditioner control device controlling an operation of the first air conditioner, and a second air conditioner control device controlling an operation of the second air conditioner, an air conditioning control device comprising:

• an optimal operation plan function creation unit calculating, by optimization calculation, an operation plan that represents changes in set values for controlling the air conditioning system so as to satisfy a range of a comfort index representing comfort of the indoor space and minimize the total energy consumption of the entire air conditioning system in the predetermined period for each combination of a value indicating the state of outside air under a plurality of conditions in a future predetermined period and a value indicating the indoor heat load for each indoor space under the plurality of conditions, for a plurality of types of the set values, and creating an optimal operation plan function, which is a function for determining the operation plan under all of the plurality of conditions for each type of the set values;
• a load fluctuation value calculation unit calculating a fluctuation value of the indoor heat load of the indoor space in the predetermined period, based on state fluctuation information including weather information;
• an operation plan determination unit specifying the set value corresponding to the fluctuation value of the indoor heat load for the predetermined period calculated by the load fluctuation value calculation unit, based on the optimal operation plan function created by the optimal operation plan function creation unit;
• and
• an operation plan transmission unit transmitting the set value specified by the operation plan determination unit to the first air conditioner control device and the second air conditioner control device.
