<p>In a method for controlling an air conditioning system including a frequency-variable power source device for providing an AC electric power of a variable frequency, and a compressor driven by the AC electric power, the air conditioning power of the conditioning system being dependent on the frequency of the AC electric power, the temperature of the air to be conditioned is detected; and a frequency set value is determined in accordance with a deviation of the detected temperature with reference to a set temperature. For determining the frequency set value, a plurality of temperature deviation zones are defined; the frequency set value is changed when the deviation transits from one of the zones to another; and the frequency set value is also changed when the deviation continues to be within one of the zones of a relatively great deviation over a predetermined length of time.</p> |
