The present invention relates to an air conditioning device which ventilates the outdoor air and indoor air by being installed in a building. The air conditioning device which improves control performance using a damper can reduce energy consumption and enhance the preheating effects to prevent dew condensation, by comprising: a casing, comprising an air inlet space connected with an air inlet through which outdoor air is inhaled, an air supply space connected with an air supply hole through which the air inhaled to the air inlet space is supplied to the indoors, a ventilating space connected with a ventilating hole through which indoor air is inhaled, and an air discharge space connected with an air discharge hole through which the indoor air inhaled to the ventilating space is discharged; a heat exchange device installed to divide the space of the casing that performs heat exchange of the outdoor air inhaled through the air inlet and the indoor air inhaled through the ventilating hole; a recirculation path formed to connect the air inlet space and the air discharge space that recirculates the indoor air flowing into the air discharge space to the air inlet space and preheats; a recirculation damper installed at the recirculation path that opens and closes the recirculation path; an air inlet damper installed at the air inlet that opens and closes the air inlet; an air discharge damper installed at the air discharge hole that opens and closes the air discharge hole; and a damper operating unit that connects by link and operates two or more among the recirculation damper, the air inlet damper, and the air discharge damper in order for two or more of them to operate at the same time. |
