Abstract:
An automatic humidity removing system using a psychrometric chart is provided to automatically drive an air conditioner according to a psychrometric chart to remove humidity from a window without additional complicated humidity removing devices or logics. An automatic humidity removing system using a psychrometric chart in a vehicle includes temperature sensors for measuring atmosphere temperature and room air temperature, a humidity sensor(120) mounted in a vehicle room for measuring internal humidity, and a control part comparing the sensing results of the sensors with a corresponding psychrometric chart to control the driving of an air conditioner. The air conditioner is driven if a crossing-over value between the temperature difference between the sensed atmosphere and room air temperatures and a relative humidity value is equal to or greater than a fog probability line value.

Abstract:
PURPOSE: A hybrid vehicle air conditioning device and a control method thereof are provided to improve the air conditioning function by securing a long valid cooling time in an ISG mode. CONSTITUTION: A hybrid vehicle air conditioning device comprises a valve way and a controller(7). The valve way controls a refrigerant, flowing in an evaporator(1), to isolates the evaporator from an expansion valve(3) and compressor(5). The valve way comprises a first solenoid valve(9) and a check valve(11). The first solenoid valve is controlled by the controller and blocks the refrigerant flowing between the evaporator and the expansion valve. The controller controls the valve member according to cooling conditions in idle stop and isolates the evaporator from the expansion valve and compressor.
Abstract:
PURPOSE: A variable radiator grille is provided to adjust the opening area of the radiator grille according to driving conditions of an engine. CONSTITUTION: In a variable radiator grille(20), plural grille plates are formed in the longitudinal direction of a case(21) to guide the external air to an engine room. The variable radiator grille comprises grille plates(22), pinion gears(30), a rack gear(40), and a reversible motor(50). Pivots(23,24) projected to the ends of the grille plate are axially combined to the sides of the inside of the case. The pinion gear is axially combined in the middle of one side of the pivots of each grille plate. The pinion gears are arranged parallel in the horizontal direction. Both ends of the rack gear are combined to the upper and lower sides of the case. Each pinion gear is simultaneously engaged with the rack gear. The reversible motor operates the rack gear to rotate the grille plates according to the driving conditions of an engine.
