Air outlet and method for its operation

摘要

The air outlet has an air exit region which has an elongated, groove-shaped indentation extending approximately over its length and in whose wall at least one air passage opening for the supply air is arranged. This indentation and the at least one air passage opening present in it are constructed or arranged so that there leads into the indentation at least one first air passage opening which is arranged at such a distance from the exit mouth of the indentation that the indentation forms, for first supply-air jets flowing into it from them, at least one compensating section.
