The calculation unit performs optimization calculation based on the ACP 20, the external air conditioner, and the heat source unit (not shown). Optimal output values (for example, temperature) of the ACP 20, the external air conditioner, and the heat source device are obtained by the optimization calculation performed by the calculation unit. The calculation unit performs an optimization calculation for each first region (for example, first regions A to D) supplied by the external air conditioner. And the apparatus control part 108 sets the output value obtained as a result of optimization calculation to ACP20, an external air conditioner, and a heat source machine.

  Note that the same output value obtained by the optimization calculation of the first region A is set as the set temperature for all ACPs 20 located in the first region A, and the first output value obtained by the optimization calculation of the first region A is The same output value obtained by the optimization calculation of one area B is set as the set temperature, and the same output value obtained by the optimization calculation of the first area C is set in all the ACPs 20 located in the first area C. Is set as the set temperature, and the same output value obtained by the optimization calculation of the first area D is set as the set temperature for all the ACPs 20 located in the first area D.

By being configured as described above, it is possible to perform control such that energy consumption is minimized while maintaining comfort through optimization calculation.
Note that the calculation unit may be configured to perform neuro PMV control instead of optimal calculation. However, it is necessary to set the second area more finely than the area where the neuro PMV control is possible. Here, the neuro PMV control is a control that reversely calculates and outputs a temperature set value from a preset PMV value, heat radiation, activity amount, clothing amount and measured humidity. By using neuro PMV control, comfort can be kept constant even when the humidity changes.
