Title: Vehicular air conditioner
Inventor: IMAEDA MASAYOSHI
IPC: B60H1/24
Filed: 1992-12-25
Abstract: PURPOSE:To provide a vehicular air conditioner allowing abundant outside air to be led into the vehicle interior without using the blower of the vehicular air conditioner or opening a body. CONSTITUTION:An internal air lead-in duct 6 leads internal air into a body duct 4 from the vehicle interior R, and an outside air lead-in duct 5 leads outside air into the body duct 4. A blower 1 in the body duct 4 blasts the internal air and outside air to the vehicle interior R through a blowoff duct 7 via heat imparting-receiving devices 2, 3. The internal air lead-in duct 6 functioning as a by-pass duct sends the outside air, flowing in from the outside air lead-in duct 5 by ram pressure caused by the travel of a vehicle, into the blowoff duct 7. An outside air straight-in control damper 51 controls the flow of outside air flowing by-passing the body duct 4 through the internal air lead-in duct 6 serving as the by-pass duct. At the ventilating time, the outside air is, after all, blown off into the vehicle interior R making a detorur around the blower 1 and the heat imparting-receiving devices 2, 3.
