PURPOSE: An air conditioner with anti-overcooling function is provided to prevent overcooling of a room. CONSTITUTION: An air conditioner includes a compressor(300) compressing refrigerant to be of high temperature and pressure; an outdoor heat exchanger(310) radiating heat of refrigerant compressed by the compressor to liquify; a first expansion valve(320) making refrigerant coming from the outdoor heat exchanger of low pressure; a first indoor heat exchanger(330) exchanging heat with refrigerant discharged through the first expansion valve; a second expansion valve(325) making refrigerant discharged from the first indoor heat exchanger of low pressure; a second indoor heat exchanger(335) exchanging heat with refrigerant discharged through the second expansion valve and outputting to the compressor; a first solenoid valve(360) connected with the first expansion valve in parallel to bypass refrigerant by opening degree thereof; a second solenoid valve(365) connected with the second expansion valve in parallel to bypass refrigerant by opening degree thereof; and a control part(340) controlling operation of the compressor and the opening degree of the first solenoid valve and the second solenoid valve.
