Abstract
A vehicular air conditioner includes a casing, a blower fan, and a heating heat exchanger. The air passage in the casing is divided into an outside air passage and an inside air passage. The heating heat exchanger is disposed downstream of the blower fan in the casing. The blower fan is disposed to extend over a first outside air space, a second outside air space, a first inside air space, and a second inside air space in the air passage. The rotational direction of the blower fan is set so that each of the plurality of blades of the blower fan passes through the first outside air space, the first inside air space, the second inside air space, and the second outside air space in this order when the plurality of blade are rotating.
