Description

Displacement ventilation diffusers deliver air from the air conditioning system at a low velocity and close to the floor. The low-turbulent airflow creates a cloud of fresh air that covers the entire floor. Convection from people and other heat sources causes a cloud of fresh air to rise upward, thereby creating comfortable conditions in the work area.

This economical form of draft-free ventilation is also suitable for use in large open-plan spaces, such as auditoriums or retail areas, with diffusers installed at equal distances from each other.

Displacement ventilation is characterized by low air flow velocity and low turbulence. The air quality in the work area is very high.

Displacement ventilation with air supply close to the floor is suitable for cooling only. The maximum temperature difference between the supply air and the room is –6 K.

The QLF series displacement ventilation diffusers are equipped with a perforated basket as a flow equalizer element, which evenly distributes the supply air over the entire diffuser area. The perforated faceplate helps further even out the airflow. Air supply in one or three directions.

With displacement ventilation, i.e. air is supplied near the floor; exhaust devices should be installed in the upper part of the room, above the work area.
