AIR CONDITIONER HAVING AUXILIARY DAMPER FOR ENERGY SAVING AND CONTROL METHOD THEREOF

摘要

The present invention relates to an air conditioner having an auxiliary damper for saving energy, capable of reducing heating or cooling time to save energy by separately installing an external air damper installed at an inlet into a main damper and an auxiliary damper, and allowing only a minimum amount of outdoor air to flow into an air mixing unit through the inlet in winter or summer, and to a control method thereof. The air conditioner comprises: a main body (102); a control unit (104) which is installed on one side of the outer surface of the main body (102) and controls the air conditioner having the auxiliary damper for saving energy in accordance with a predetermined program; an air mixing unit (112) which is installed on one side of the inside of the main body (102), discharges a part of the indoor air transmitted from a suction unit (106) to the outside through an outlet (E·A) installed on one side of the upper surface thereof, mixes the remaining air and the outdoor air flowing through a first inlet (108) or a second inlet (110), obtained by dividing the inlet (O·A) installed on one side of the upper surface with a predetermined interval from the outlet (E·A) into two parts, and transmits the mixed air to a heat exchange unit; and a CO_2 sensor (118) which is installed on one side of the outlet (E·A) of the air mixing unit (112), and is electrically connected to the control unit (104) to sense CO_2 in the indoor air in accordance with a control signal of the control unit (104).;COPYRIGHT KIPO 2017
