Abstract
The present invention relates to a center mounting type air conditioner for a vehicle, which can reduce size and noise of a blower, and enhance installation efficiency and reduce an installation space of the air conditioner installed in the vehicle. At least one bypass passageway is formed in a dead space located between the scroll case and the air conditioning case, whereby some of air sucked from the intake duct is bypassed and sucked toward the second wheel of the dual blower wheel, to which the motor is connected.
Claims12

- a vehicle having an upper part and lower part;
- a blower having a scroll case, which has an inlet and an outlet, an intake duct mounted at the inlet of the scroll case and having an indoor air intake port and an outdoor air intake port, the indoor air intake port and the outdoor air intake port being adjusted in their opening by an intake door, a dual blower wheel rotatably mounted inside the scroll case and having first and second wheels for sucking and blowing air bi-directionally, and a motor for rotating the dual blower wheel;
- an air conditioning case having an upper part parallel to said upper part of said vehicle, an inlet and outlet, the inlet being connected to the outlet of the scroll case, the outlet having a number of air vents which are respectively adjusted in their opening by doors, an evaporator and a heater core being mounted inside the air conditioning case;
- and
- a bypass passageway enclosed within a gap between a cut-off area where a scroll part and the outlet of the scroll case meet together and the air conditioning case in which the upper part of the evaporator is positioned, wherein said bypass passageway is configured to receive and bypass said first wheel some of the air from said intake duct located upstream of said inlet of said air conditioner case and wherein said bypassed air is then sucked toward the second wheel of the dual blower wheel, to which the motor is connected;
- and
- wherein the scroll case is arranged on and is connected to the upper part of the air conditioning case.
