Abstract: A slim air vent for a vehicle includes an inner wing disposed in a duct to horizontally rotate during manipulation of a knob, an outer wing and a support wing disposed in the duct to vertically rotate during the manipulation of the knob, a knob pin horizontally penetrating through the knob to rotate together with the knob during the vertical rotation of the knob and to guide the knob during the horizontal movement of the knob, and a link mechanism provided to connect one end of the knob pin and the outer wing to vertically rotate the outer wing and the support wing during rotation of the knob pin according to the vertical rotation of the knob.

Abstract: A heating, ventilating, and air conditioning (HVAC) apparatus for a vehicle includes: a case, which is configured to communicate with the outside of the vehicle and which includes a discharge flow path connected to an interior of the vehicle; an outside air inlet, which is located in the case and into which air is introduced from the outside of the vehicle; an inside air inlet configured to communicate with the interior of the vehicle; a filter unit located adjacent to the discharge flow path; an inside/outside air switching door provided adjacent to the outside air inlet and the inside air inlet and configured to selectively open the outside air inlet and the inside air inlet; and an auxiliary switching door, which includes a depression located at a lower end of the filter unit and which is selectively opened so as to allow the depression and an outdoor outlet to be fluidly connected.

Abstract: A vehicle air conditioning system performing individual air conditioning in four zones for left and right spaces of front and rear seats includes a front seat heating, ventilation, and air conditioner (HVAC) separately supplying air having passed through left and right flow paths of a front seat flow path into the left and right spaces of the front seat to perform two-zone individual air conditioning for the front seat. A flow guide is provided in an upstream side space of an evaporator in an internal space of the air conditioning casing of the front seat HVAC to divide the upstream side space of the evaporator to have a left flow path and a right flow path. The flow guide and a side portion of the air conditioning casing opposite to the flow guide have a curved stepped portion in cross-section.

Abstract: An individual air conditioning control system for an electric vehicle, includes a heating, ventilation, and air conditioning (HVAC) body, an evaporator provided in the HVAC body, a PTC heater, an input unit for receiving set temperature of each of a driver's seat and a passenger's seat, left and right temperature sensing units of sensing an air temperature passing through a left side and a right side of the PTC heater, a control unit of outputting a control signal for controlling the PTC heater based on the set temperature input from the input unit and a measurement temperature measured from each of the left and right temperature sensing units, and a power supply unit of adjusting power supplied to the PTC heater according to the output PWM control signal of the control unit.
