WIPO Patent Application WO/2023/018074
Kind Code:
A1
Abstract:
The present invention relates to a vehicle air conditioner, which can compensate for a reduction in air intake due to suction ventilation resistance of a moisture inflow blocking wall on a cowl side in an outside air mode, and through this feature, the purpose of the present invention is to prevent a change in the temperature of discharged air in a vehicle interior due to the reduction in air intake in the outside air mode, and deterioration in cooling and heating performance in the vehicle interior due to the change. In order to achieve this object, the vehicle air conditioner of the present invention, which comprises: an intake door that introduces outside air by opening an outside air entrance in the outside air mode, introduces inside air by opening an inside air entrance in an inside air mode, and opens and closes the outside air entrance or the inside air entrance; and an intake unit equipped with a blower that sucks in inside and outside air through the inside and outside air entrances and blows air into the vehicle interior, comprises a control unit that controls the rotational speed of the blower according to the number of air flow rates of the air conditioner, wherein the control unit differentially controls the rotational speed of the blower according to an air intake mode at the same air flow rate.
