Roof ventilator for wide openings in roofs - has rain protection covers also acting as guide walls for ejected airflows

摘要

The ventilator incorporates an open housing with a baffle wall ceiling (5). Several driven rain protection covers (9) are located to the side of the ceiling. In open position, the covers form guide walls for the outflowing air. The journal pins (8) of the covers are located in a plane, which is slightly inclined relative to the baffle ceiling. The rain protection covers are double-armed and slightly curved. USE/ADVANTAGE - In industries with heat-intensive technologies, which eject large convection and radiation heat flows to the atmosphere. Can be adjusted to variations in weather conditions.
