Abstract: An air conditioning system for a vehicle is provided. The system includes a cooling duct and a heating duct provided as spaces partitioned by a partition wall and an evaporator core and an inner condenser disposed respectively in the cooling and heating ducts. An outer condenser is connected to the inner condenser and the evaporator core via one refrigerant passage. An air volume regulation door is disposed upstream of the evaporator core and the inner condenser in an air flow direction, and a common blower is disposed at one side of the cooling and heating ducts to simultaneously form an air flow in the cooling and heating ducts.

Abstract: An automatic dust removal device for a vehicle is provided. The device constantly senses dust in the interior of the vehicle and automatically removes the detected dust. The device includes a dust sensor that senses dust concentration in the interior of the vehicle and a controller that operates an air-conditioning device. The controller determines whether dust in the interior of the vehicle requires removal based on a signal from the dust sensor. An air-conditioning device for removing dust from the air is operated to activate a dust removal mode based on a signal from the controller. Thus, an intake door is closed to block inflow of external air into the interior of the vehicle and the air in the interior of the vehicle passes through an air filter and is circulated by a blower.

Abstract: An air condition and lamp control system based on a light sensing of a vehicle may include an illumination sensor configured to detect an amount of irradiation of light irradiated into an interior side of the vehicle to be distinguished in a left and a right, an air condition controller configured to receive a left input voltage and a right input voltage according to the amount of irradiation of light detected by the illumination sensor and to independently compensate for left and right interior temperatures, a voltage amplifier configured to sum the left input voltage and the right input voltage which are transferred from the illumination sensor and to amplify the summed voltage to an amplified voltage, and a lamp controller configured to receive the amplified voltage amplified by the voltage amplifier, to compare the amplified voltage and a prestored lamp operation voltage, and to drive a lamp apparatus.

Abstract: A stall diagnosis apparatus for a motor of an air conditioning actuator includes: a resistor connecting from a first door actuator of a Heating, Ventilation and Air Conditioning (HVAC) system of a vehicle to the ground; a resistor connection circuit connecting from a VCC power terminal to the resistor; a switch disposed on the resistor connection circuit; a first circuit and a second circuit branched from a motor connection circuit connecting from the VCC power terminal to a motor of the first door actuator through a motor driver and the resistor connection circuit, respectively; a current sensing circuit unit including an input terminal connected to the first circuit and the second circuit and outputting a current signal corresponding to a voltage value between the motor connection circuit and the resistor connection circuit; and a controller for controlling the motor and determining whether or not the motor is stalled.
