1. An air-conditioning control system, comprising:

  • an air conditioner;

    a central heat source device;

    an air-conditioning controller for controlling operations the air conditioner and the central heat source device; and

    a measurement device provided for a room or control zones divided in the room subject to an air-conditioning control, the measurement device for measuring temperature and humidity subject to the air-conditioning control,the air conditioner, the central heat source device, the air-conditioning controller, and the measurement device being connected, wherein the measurement device comprises a measured value transmitter for obtaining a temperature measured value and a humidity measured value measured in the room or the control zones in the room subject to the air-conditioning control, so as to send the obtained values to the air-conditioning controller;

    the air conditioner comprises;

    an outer air coil for introducing a certain amount of outer air, the outer air coil for controlling temperature and humidity of the introduced outer air based on a temperature set value and a humidity set value obtained from the air-conditioning controller;

    a return air coil for introducing a certain amount of return air from the room or the control zones in the room subject to the air-conditioning control, the return air coil for controlling temperature of the introduced return air based on the temperature set value obtained from the air-conditioning controller; and

    a blast fan for producing a mixed air of the outer air of which the temperature and humidity are controlled by the outer air cooling coil and the return air of which the temperature is controlled by the return air cooling coil, the blast fan for supplying the mixed air to the room or the control zones in the room subject to the air-conditioning control,the central heat source device comprises;

    a cold/hot water controller comprising a refrigerator and a cooling tower, the cold/hot water controller for controlling a water temperature based on a water temperature set value obtained from the air-conditioning controller, thereby generating cold water or hot water to supply to the air conditioner; and

    a water pump for supplying the cold water or the hot water generated in the cold/hot water controller to at least one of the outer air coil and the return air coil of the air conditioner based on a flow rate value obtained from the air-conditioning controller, andthe air-conditioning controller comprises;

    a measured value obtaining unit for obtaining the temperature measured value and the humidity measured value sent from the measured value transmitter of the measurement device;

    a comfort index range recorder for storing a preset target set range of a comfort index;

    an air conditioner set value calculator for calculating a temperature set value and a humidity set value of air supplied from the air conditioner within the target set range of the comfort index stored in the comfort index range recorder based on the temperature measured value and the humidity measured value obtained in the measured value obtaining unit, so that a sum of consumption energies of the refrigerator, the cooling tower, the outer air coil, the return air coil, the water pump, and the blast fan is a minimum value;

    a set value transmitter for sending the temperature set value and the humidity set value calculated in the air conditioner set value calculator to the air conditioner; and

    a control value transmitter for calculating a water temperature set value and a flow rate value of the cold water or the hot water according to the temperature set value and the humidity set value calculated in the air conditioner set value calculator, so as to send the calculated values to the central heat source device.
