Abstract:
An air conditioning system for a vehicle comprising:a casing; an evaporator mounted substantially in an upright position at a front portion within the casing; a heater core mounted substantially in an upright position at a rear side of the evaporator; a mixing area located at a rear side of the evaporator and an upper side of the heater core for mixing a first air bypassing the heater core with a second air flowing through the heater core; a partition plate for guiding the second air to the mixing area after the second air flows through the heater core; a foot passage defined by a rear portion of the casing and the partition plate; a defrosting passage communicating with a lower end of the foot passage and extending along an outer surface of the casing to the upper portion of the casing; a vent outlet provided at a portion near the mixing area of the casing; a defrosting outlet provided at an upper end of the defrosting passage; a temperature controlling damper for controlling rates of the first air bypassing the heater core and the second air flowing through the heater core after the first and second airs flow through the evaporator so as to attain a predetermined final temperature of the air which is discharged into a passenger compartment of the vehicle; a vent damper for opening and closing the vent outlet; a foot damper for opening and closing a foot outlet for the foot passage; and a defrosting damper for opening and closing the defrosting outlet, wherein said vent, foot and defrosting outlets are positioned along the casing such that, in the downstream area of the evaporator, the vent outlet is the nearest to the evaporator, the defrost outlet is the farthest from the evaporator, and the foot outlet is located between the vent outlet and the defrosting outlet.
