Abstract
A method and an apparatus for ventilating at least one window in a vehicle by blowing and extracting air in a region of the window is described. The airflow blown against the window is substantially laminar and the air is extracted in an upper region of the window. A dew point is lower than the window temperature in a region of extraction being the upper region of the window, and an absolute humidity of the blown air is lower than that of the extracted air.
Claims6
A method of ventilating at least one window of a vehicle, which comprises the steps of:
- blowing a substantially laminar flow of air in a region of the window;
- extracting the air from a region of extraction of the window being an upper zone of the window, a dew point in the region of extraction being lower than a window temperature in the region of extraction, and an absolute humidity of the air blown against the window being lower than that of the extracted air;
- and
- determining a relative atmospheric humidity, a temperature of the extracted air, the window temperature, and a relative humidity and a temperature of the air blown along the window.
An apparatus for controlling a ventilation of at least one window of a vehicle, comprising:
- an air blowing device feeding air along a region of the window;
- an air extracting device for extracting the air from an upper zone of the window;
- and
- sensor elements connected to said air blowing device and disposed in a region of the window for controlling a temperature, a humidity and a velocity of the air.
