Claim:
1. An air conditioning control system comprising: a temperature and humidity adjustment coil that performs adjustment of temperature and humidity of air as a control subject; a first damper that is placed in an air pipe coupling outside air and the temperature and humidity adjustment coil to each other, and adjusts an intake volume of the outside air; a second damper that is placed in an air pipe coupling a space of a room inside as an air conditioning control subject and the temperature and humidity adjustment coil to each other, and adjusts an intake volume of return air from the room inside; a damper control unit that alternately switches outside air control and return air control at a fixed time switching interval, in which the outside air control is to take the outside air into the temperature and humidity adjustment coil for dehumidifying the outside air by opening the first damper at a degree of opening for controlling an introducing amount of the outside air based on a required ventilation volume of the outside air required in the room inside and fully closing the second damper to shut out the return air, and the return air control is to take the return air from the room inside into the temperature and humidity adjustment coil for controlling a temperature of the return air by fully closing the first damper to shut out the outside air and opening the second damper to introduce only the return air, wherein the required ventilation volume is determined based on a floor area and an occupied area per person.
