Description

Technology Field

[0001] The present invention relates to a roof air conditioning system for a vehicle, and more specifically, to a roof air conditioning system for a vehicle that is installed on the roof of a vehicle and discharges air sucked in from the rear seat side of the vehicle to the second and third seats. Background Technology

[0002] Generally, a vehicle air conditioning system draws air supplied from outside the vehicle or air recirculated inside the vehicle into the system through a blower, passes it through an evaporator installed inside, and then selectively passes it through a heater core to perform heat exchange, thereby forming cold or warm air, and distributes the formed cold or warm air to various zones inside the vehicle according to the operating mode, thereby serving to cool or heat the interior of the vehicle.

[0003] On the exterior of the casing of this air conditioning system, multiple vents are formed for discharging air into the vehicle's interior seats, and the airflow discharged from each vent is distributed to various zones within the vehicle, such as the windshield, the center and sides of the front seats, and the rear seats, through various types of ducts.

[0004] These air conditioning systems are generally formed in front of the front seats of the vehicle, extending from the instrument panel of the front seat to the passenger seat. However, in cases where the interior space is large, such as in leisure vehicles with six or more seats, a separate air conditioning system may be installed at the rear of the vehicle to provide air conditioning for the rear seats, i.e., the rear seats.

[0005] According to conventional vehicle roof air conditioning systems, there is a problem in that it is difficult to smoothly distribute airflow between the front row (2 seats) and the rear row (3 seats) of the vehicle's rear seats. In addition, there is a problem in that the height and width of the vehicle roof air conditioning system are somewhat large, so it can only be installed between the front and rear seats to consider passenger convenience.
