Abstract:
The present invention effectively prevents exhaust gas from flowing into an indoor space of a vehicle as pressure of the indoor space of the vehicle decreases, and prevents heating and cooling performance degradation of an air conditioner. To achieve this, the present invention simplifies the structure of a blower unit of the air conditioner using small number of components and facilitates adjustment for the intake rate of external air to the blower unit.

Abstract:
PURPOSE: A dehydrating method for an evaporator in an air-conditioner of a vehicle is provided to prevent problems caused by depletion of a battery and enable the evaporator to be properly dried as well by monitoring the dried state of the evaporator and driving a blower motor according to the humidity of the evaporator. CONSTITUTION: A dehydrating method for an evaporator in an air-conditioner of a vehicle is as follows. When an engine is off, whether the voltage of a battery is over a reference voltage is determined(S10). Whether the air-conditioner had operated before the engine off is determined(S20). If the battery voltage is over the reference voltage and the air-conditioner had operated, the humidity of air blown by a blower motor is sensed by a humidity sensor(S30). Whether the sensed humidity is over a reference humidity is determined(S40). If the sensed humidity is over the reference humidity, a changeover period between a defog mode and a vent mode and a driving voltage of the blower motor are set according to the sensed humidity(S50). An air-conditioning mode is changed according to the set conditions and the set driving voltage is applied to the blower motor, thereby drying an evaporator(S60). Whether the changeover period between the defog mode and the vent mode is reached is determined during the drying step and, if so, the vent mode is changed into the defog mode and control is returned to the humidity sensing step(S70). [Reference numerals] (AA) Start(Engine OFF); (BB) Switch into a defog mode; (CC) Convert a TEMP door to a MAX COOL mode; (DD) Drive a blower motor; (EE) Switch into a defog mode; (FF) End; (S10) Battery voltage >= Reference voltage ?; (S20) Air-conditioner operated before the engine OFF?; (S30) Sense the humidity of blowing wind with a humidity sensor(of windshield glass); (S40) Sensed humidity >= Reference humidity ?; (S50) Set a mode changeover period and set a blower motor driving voltage; (S60) Change into a vent mode and apply the blower motor driving voltage; (S70) Mode changeover period reached?
Abstract:
PURPOSE: A method and a system for controlling the air conditioning of a vehicle using an infrared sensor for measuring vehicle temperature with a multi-divided measuring method are provided to obtain temperature information of a target object. CONSTITUTION: A system for controlling the air conditioning of a vehicle comprises an infrared sensor and a controller. The system for controlling the air conditioning of a vehicle detects the temperature of multipld divided cell areas(S512,S514,S516). The controller compares the temperature value of each area with a target temperature value(S520). When a difference between the temperature value of each area and the target temperature value is lower or the same as a critical value, a current air conditioning control is maintained(S555). When the difference is higher than the critical value, the air conditioning control is performed by differentiating the critical value.

PURPOSE: An air extractor grille device for an automobile is provided to improve rigidity of a flap door and vent performance in the automobile, and to minimize noise generated during opening and closing of a trunk lid or a door of the automobile. CONSTITUTION: A silicon member(33) is formed with double injection method, and attached to a part on which a chassis panel and a grille frame(31) are contact with each other to prevent water leakage on the attached part. A thin flap door(37) is mounted on an upper side of a grille blade part(35) having an opening(35a), a channel through which air in a vehicle is discharged to the outside. Material of the flap door is formed with extrusion, and cut to form the flap door to prevent deformation due to fluctuation of temperature or long use. Fine protruded parts are formed on a lower side of the flap door contacting with an upper side of the grill blade part so as to allow air to be freely discharged and to prevent deformation of the flap door due to particles even when particles such as dust is interposed.
