The invention relates to an intelligent air conditioner system based on gas entropy change measurement. The intelligent air conditioner system comprises an air acquisition module, a working module, aprocessing module, a reaction module and a control module. The air acquisition module is connected with the working module, the working module is connected with the processing module, the processing module is connected with the reaction module, and the reaction module is connected with the control module. The air acquisition module is used for acquiring indoor gas. The working module is used for carrying out an entropy thermoelectric physical reaction on the acquired gas. The working module carries out digital electronic signaling conversion according to the thermoelectric physical reaction ofthe working module. The conversion result is a digital signal corresponding to entropy increment of the currently acquired gas. The processing module is used for carrying out current air state speculation according to a digital signal conversed by the working module. The reaction module is used for making a corresponding control command reaction on the air state speculated by the processing module. The control module makes an adjustment of the working state of an intelligent air conditioner according to the control command obtained by the reaction of the reaction module.
