Abstract:
An air conditioning system mountable in the rear of a vehicle having a vent mode and a foot mode, the air conditioning system comprising:a casing; an evaporator mounted at an upper front portion within the casing; a heater core mounted below the evaporator such that an upper end of the heater core is located below a bottom end of the evaporator; a vent outlet provided at an upper rear portion of the casing for allowing the air having a first selected final temperature to be discharged into a passenger compartment of the vehicle in the vent mode; a foot outlet provided at a front portion of the casing for allowing the air having a second selected final temperature to be discharged into the passenger compartment in the foot mode; a first bypass passage extending between a downstream side of the evaporator and the vent outlet; a second bypass passage extending between the downstream side of the evaporator and the foot outlet; a first heater core passage providing a fluid communication between the rear side of the heater core and the first bypass passage; a second heater core passage providing a fluid communication between the front side of the heater core and the second bypass passage; and a temperature controlling damper for controlling a rate of air which is directed toward the heater core so as to attain the first or second selected temperature of the air for discharging into the passenger compartment of the vehicle, wherein said temperature controlling damper controls a proportion in which the rate of the air is divided into the first bypass passage and the second bypass passage.
