The WiVent-B decentralised ventilation unit provides pure air in classrooms and conference rooms – almost as if you were outdoors. It doesn't matter at all if it is a new building or a renovated building. Sensors detect both the outdoor and indoor temperature and the CO2 content in the indoor air, regulating the ventilation system in accordance with the requirement. However, the teacher can also set the temperature and ventilation level of the ventilation units individually via various control units.
Can the decentralised ventilation be adapted automatically to the temporal use of the classrooms?
The control of the decentralised ventilation can be adapted to the individual use of the classrooms to the day or the exact minute. For this purpose, there are six different operating modes which can be allocated to up to 12 time windows. These can also be configured for times when the school is not in use, for example during holidays.
Which requirements should be fulfilled by the school building or classrooms?
Can the windows of the classroom still be used for ventilation?
Does a room control unit have to be installed in every classroom?
How much work is required for servicing of the ventilation unit?
Fresh air with a low CO2 concentration increases the ability to concentrate. That is why it is particularly important in schools that the students in the classrooms are supplied with sufficient fresh air. The WiVent-B school ventilation system provides the pupils and teachers in the classroom with a stable room climate with good air quality, even with varying occupancy rates. The key: a special reversing flap allows you to switch between low-turbulence displacement air flow and strong-impulse mixed air flow to suit the requirement. The CO2 control of the WiVent-B specifically ensures compliance with the specified limit values.
In operation with displacement air flow, the supply air enters the classroom across the entire width of the unit through to the open change-over flap. With a low flow impulse and minimal under temperature, the supply air is distributed over a large area on the floor of the entire room with little turbulence and forms a fresh air lake. At heat sources such as pupils, the air finally rises, thus ensuring optimum air quality.
In operation with mixed air flow, the closed change-over flap reduces the outflow cross-section. As a result, the air penetrates far into the classroom with a higher flow momentum. This ensures that the room is flushed more quickly and efficiently. When heating, the ventilation unit replaces the radiator.
Even in an equipped and occupied classroom, the goal must be to achieve a very good ventilation result. For ventilation with displacement air flow, the reliable formation of the fresh air lake is considered an important basis. Obstacles such as school satchels cannot prevent a well implemented displacement flow from forming a fresh air lake.
Even in winter, the decentralised school ventilation WiVent-B ensures a pleasant learning temperature. In order to bring the supply air into the room during heating, a greater impulse is necessary due to its higher temperature. This is achieved with the help of a special changeover damper. A good flushing of the room is also guaranteed with this type of flow.
