<p>PURPOSE:To make it possible to control airconditioning with high accuracy and good response, by forecasting or seeking by actual measurements control deviation by temperature control and repeatedly correcting the characteristics of a temperature control system, and at the same time by selecting skilfully the timing of the correction. CONSTITUTION:A microcomputer 21 is provided to control the driving of a blower 11, air-mix damper 14, etc. installed in an air conditioning duct 10. This microcomputer 21 issues control signals based on outputs from inside and outside air temperature sensors 15 and 16, a sun shine sensor 17, and room temperature and air flow rate setting devices 18 and 19. Namely, the microcomputer 21 seeks the temperature regulation value in order to stabilize the inside temperature to the target value by the outputs from the sensors and setting devices, and issues instruction signals to each of the driving circuits 23 and 24 according to this regulation value. Further, the microcomputer monitors repeatedly control deviations by this control with respect to the target value for inside air temperature, and, if it is larger than a prescribed value, it is operated to correct the external disturbance parameter.</p> |
