Central air conditioning system

A central air conditioning system comprising:

• dampers configured to individually air-condition a plurality of spaces;
• an air conditioning controller configured to instruct the dampers to perform a control operation for the individual air conditioning of the plurality of spaces;
• a temperature sensor disposed in each of the plurality of spaces and configured to:
• detect a temperature at sampling time intervals;
• predict a temperature based on a temperature gradient calculated last time;
• determine whether a difference between the predicted temperature and the actually detected temperature exceeds a certain range;
• and
• newly calculate the temperature gradient and transmit the calculated temperature gradient together with the detected temperature via a wireless communication when the difference between the predicted temperature and the actually detected temperature is determined to exceed the certain range;
• and
• a temperature predictor, upon receiving the temperature and the calculated temperature gradient, configured to:
• predict a temperature in each of the plurality of spaces to generate temperature information depending on elapsed time that passes from the timing of the receiving of the temperature and the calculated temperature gradient;
• and
• transmit the temperature information to the air conditioning controller.

• a temperature sensor disposed in each of the plurality of spaces and configured to:
• detect a temperature at sampling time intervals;
• predict a temperature by using one of multiple prediction formulae which have been stored in the temperature sensor in advance for temperature prediction;
• and
• newly select another of the multiple prediction formulae and transmit information of the detected temperature and the selected prediction formula when a difference between the predicted temperature and the actually detected temperature exceeds a certain range;
• and
• a temperature predictor, upon receiving the information of the detected temperature and the selected prediction formula, configured to:
• predict a temperature in each of the plurality of spaces by using the selected prediction formula to generate temperature information depending on elapsed time that passes from the timing of the receiving of the information of the detected temperature and the selected prediction formula;
