Description

Air Conditioner for Vehicle The present invention relates to a vehicle air conditioning system, and more specifically, to a vehicle air conditioning system configured to perform independent air conditioning control in four different areas of the vehicle interior. Generally, a vehicle air conditioning system is an interior component of a vehicle installed for the purpose of cooling or heating the vehicle's interior during the summer or winter, or removing frost that forms on the windshield during rain or winter, so that the driver can maintain a clear view of the front and rear. The air conditioning system is typically equipped with both a heating system and a cooling system, and selectively introduces outside or inside air to heat or cool the air and then blows it into the vehicle's interior to cool, heat, or ventilate the vehicle's interior. Korean Registered Patent Publication No. 1484718 (Jan. 14, 2015), filed prior, discloses a vehicle air conditioning system that controls the rear airflow by controlling the positions of a rear seat temp door, a rear seat auxiliary temp door, and a rear seat on/off door. Referring to FIG. 1, the vehicle air conditioning system includes an air conditioning case (10), an evaporator (20) and a heater core (30), a front seat temp door (51) and a front seat mode door. The air conditioning case (10) is equipped with an air inlet (11) and an air outlet, and an air passage is formed inside. A blower is connected to the air inlet (11) so that indoor or outdoor air is selectively introduced into the air passage inside the air conditioning case (10). The air outlet consists of a defrost vent (12), a front seat face vent (13), a front seat floor vent (14), a rear seat face vent (15), and a rear seat floor vent (16). The air passage inside the air conditioning case (10) consists of a front seat cooling passage (P1), a heating passage (P2), and a rear seat cooling passage (P3). The evaporator (20) is a cooling heat exchanger that cools the air passing through it, and the heater core (30) is a heating heat exchanger that heats the air passing through it. The heater core (30) is positioned in the heating path (P2) downstream of the evaporator (20) in the direction of air flow. An electric heater (40), such as a PTC heater, may be further provided in the heating path (P2). The electric temperature door (51) is positioned between the evaporator (20) and the heater core (30) to control the opening of the heating path (P2) passing through the heater core (30) and the cooling paths (P1) (P3) bypassing the heater core (30). Additionally, the electric temperature door is composed of a defrost door (53), a vent door (54), and a floor door (55). The rear air passage consists of a rear cooling passage (P3) through which air passing through the evaporator (20) bypasses the heater core (30) and a heating passage passing through the heater core (30). The heating passage of this rear air passage is used together with the heating passage (P2) of the front air passage. That is, a portion of the air flowing through the heating passage (P2) after passing through the heater core (30) moves upward and is discharged to at least one of the defrost vent (12), front face vent (13), and front floor vent (114), while another portion of the air moves downward and is discharged to at least one of the rear face vent (15) and rear floor vent (16). The rear air passage is equipped with a rear mode door (58) that controls the opening of the rear face vent (15) and the rear floor vent (16). Inside the air conditioning case (10), a rear seat temp door (52), a rear seat auxiliary temp door (56), and a rear seat on/off door (57) are provided. The rear seat temp door (52) is provided between the evaporator (20) and the heater core (30) to control the opening of the passage flowing into the heating passage (P2) and the passage flowing into the rear seat cooling passage (P3), and the rear seat auxiliary temp door (56) is positioned on the downstream side of the heater core (30) in the direction of air flow to control the opening of the passage flowing into the rear seat air outlet. The rear seat on/off door (57) controls the opening of the rear seat cooling passage (P3). Conventional vehicle air conditioning systems are structured to enable independent left-right air conditioning for the front seats but not for the rear seats, allowing for 3-zone air conditioning control but not 4-zone air conditioning control. In other words, conventional vehicle air conditioning systems do not reflect a layout for 4-zone air conditioning control, and temperature control methods for each zone are not specified. In addition, conventional vehicle air conditioning systems had limitations in expanding the degree of freedom of air conditioning because they could not individually control not only the temperature but also the air conditioning mode and airflow for four independent zones (4-Zone). If an air conditioning system capable of independen
