Energy-saving ventilation system for revolving door involves blower sucking necessary amounts of air from building inner area via suction channel

摘要

The energy-saving ventilation system, avoiding the creation of cold areas, is provided for a revolving door which has several door panels (13) fixed to a rotary cross, around a rotational axis. The panels are enclosed by curved drum walls (1,2) interrupted by an entry and an exit (3,4). The ventilation system sucks the amounts of air necessary for ventilation from a building inner area (11) via a suction channel (8) using a blower (9). The air is blown out via two diametrically opposed vertical channels (5,6) with blow-out channels, which at the same time are connected with a horizontal channel (7) with a blow-out channel in the ceiling of the revolving door.
