AIR CONDITIONING DEVICE FOR VEHICLES

WIPO Patent Application WO/2018/150735

A1

The present disclosure provides an air conditioning device for vehicles that comprises a seat air conditioning unit and a vehicle interior air conditioning unit including a heat accumulation unit, wherein improving cooling efficiency is possible using the cold/heat accumulated by the heat accumulation unit. The air conditioning device for vehicles is provided with a vehicle interior air conditioning unit (10), a seat air conditioning unit (40), and a control unit (50) for controlling the operation of the vehicle interior air conditioning unit and the seat air conditioning unit. The vehicle interior air conditioning unit comprises: an interior air blower (17) for blowing air towards the vehicle interior; a cooling unit (20) for cooling the blowing air blown by the interior air blower; and a heat accumulation unit (21e) for accumulating cold/heat generated by the cooling unit. The seat air conditioning unit comprises: ventilation openings (42, 46) formed in a seat (5) arranged in the vehicle interior; and seat air blowers (44, 48) for drawing in air in the vehicle interior through the ventilation openings. The control unit cools the blowing air by the cold/heat accumulated in the heat accumulation unit, and if the seat air conditioning unit is operated, reduces the air conditioning performance of the vehicle interior air conditioning unit.
