Abstract: A defroster nozzle of a vehicle installed below a windshield of the vehicle and discharging conditioned air toward the windshield, the defroster nozzle generating vortex during discharging is disclosed. The defroster nozzle may include a housing formed in a cylindrical shape and having an inlet formed at one end of the housing through which the conditioned air is introduced, and an outlet formed adjacent to the windshield through which the air is discharged, and a vortex generator configured to protrude from an inner side surface of the housing to discharge the air introduced into the housing as vortex in the inner side surface of the housing.

Abstract: A method and an apparatus for controlling a compressor are provided. The method includes measuring a vehicle speed, an engine speed, a position value of an accelerator pedal, and an external air temperature and comparing the vehicle speed with a predetermined speed. A basic operation rate of the compressor is then determined based on the engine speed and the position value of the accelerator pedal when the vehicle speed is equal to or less than the predetermined speed. A final operation rate of the compressor is determined based on the external air temperature and the determined basic operation rate and the compressor is operated based on the determined final operation rate.

Abstract: A compressor control apparatus may include a data detector detecting status data including at least one of vehicle speed, engine speed, accelerator pedal location value, and slope way measurement value; and controller that determines whether engine speed and accelerator pedal location value of the status data satisfy oscillation acceleration entering condition, if the vehicle speed exists in predetermined range and that sets basic operation rate of compressor according to the engine speed and the accelerator pedal location value, if engine speed and accelerator pedal location value of the status data satisfy oscillation acceleration entering condition and that generates final operation rate of the compressor using the basic operation rate, slope way constant according to the slope way measurement value, and air temperature compensation constant according to air temperature and that controls operation of the compressor based on the final operation rate.
