  • Patent number: 9919576
    Abstract: An air conditioner for a vehicle and a method of controlling the air conditioner to variably control a position of a rear seat cold air control door depending on a position of a front seat temperature-adjusting door. The position of the rear seat cold air control door is controlled according to rear seat air-conditioning modes (rear seat temperature-adjusting modes). In an air-conditioning case, the rear seat cold air control door is mounted on a rear seat air passageway, thereby distributing an optimal volume of cold air to the front seat air passageway and the rear seat air passageway by preventing a large volume of cold air from being supplied to the rear seat air passageway in the rear seat temperature-adjusting mode, securing linearity of temperature discharged to the rear seat.
