FIELD: ventilation.
SUBSTANCE: heating and cooling ceiling unit is mounted on the ceiling of the room and is made in the form of an air duct through which airflow moves, coming from the air cooler with a fan, and having an inlet and an outlet connected to the building ventilation system and forming a closed system. The air duct is formed of a horizontal partition that separates the room from the ceiling slab to which it is secured by the frame elements, and dividing the internal volume to interconnected hollow cells forming a smooth aerodynamic channel of zigzag (labyrinthine) form. In the horizontal partition the holes are made for release of part of the air in the space in volume of from 10 to 50% of the circulating flow.
EFFECT: increase in comfort of long-term presence in the office due to eliminating the directed flows of cooled air and the quietness of the device.
