VEHICULAR AIR CONDITIONER

摘要

In a vehicular air conditioner in which heat of recirculated air inputted by an indoor air blower, is exchanged by an indoor heat exchanger so as to be retransmitted to a vehicle, there are provided with a cyclone fan, which aspirates heavy fresh outside air including snow or the like, so as to mix the outside air with the recirculated air inputted by the indoor air blower, and a partition plate, which separates light air in which snow or the like is not included, and heavy air in which snow or the like is included, by centrifugal force of the cyclone fan at a blowoff outlet of the cyclone fan.

主权项

1. A vehicular air conditioner comprising:
an indoor equipment room which is composed of at least an indoor air blower and an indoor heat exchanger, wherein outside air inputted from an outside-air inlet is mixed with recirculated air aspirated by the indoor air blower, and then the mixed air is fed to a cabin via the indoor heat exchanger; a cyclone fan for separating the inputted outside air to outside air of which mass is lighter than a predetermined mass, and outside air of which mass is heavier than a predetermined mass, by centrifugal force; and a partition plate for partitioning a passage of the outside air, of which mass is lighter than the predetermined mass, and a passage of the outside air of which mass is heavier than the predetermined mass, at a blowoff outlet of the cyclone fan.
