PROBLEM TO BE SOLVED: To ensure the cost-down in maintenance by executing radio communication when the environment information on an air conditioning control space has changed exceeding a predetermined value compared with the time of previous radio communication or when a predetermined time has elapsed from the time of previous radio communication. SOLUTION: The air conditioning control system comprises a radio communication parent station 1, a plurality of radio communication child stations 2 connected with the parent station 1 through a radio communication channel and disposed in an air conditioning control space 100 being an object to be controlled for air conditioning, and an air conditioning controller 4 for controlling the air conditioner 3. When measured temperature of the air conditioning control space 100 is judged to be over by a predetermined value from the previous temperature, the operation is advanced to radio communication between it and the parent station 1. Further, even when there is continued a situation where the measured temperature is judged not to be over the predetermined value from the previous temperature, provided the time is judged to be elapsed by 30 minutes from the previous communication, radio communication is forcibly executed between the parent station 1 corresponding to the child station 2 and the child station 2. |
