Ventilation units and systems for aeration and ventilation in schools
Aeration/ventilation of school building
Fresh air is key to well-being. In rooms full of large numbers of people where aeration is sporadic, e.g. by opening windows during breaks, oxygen very quickly turns into CO2. The consequences of increased levels of CO2 in room air are a diminishing ability to concentrate, tiredness and headaches.
Keeping super fit day after day and maintaining concentration levels requires fresh and healthy air in all rooms. Classrooms, staff rooms, kitchen or toilet – effective ventilation produces optimum conditions for learning and teaching!
To give pupils and teachers the optimum conditions in which to work, classrooms should be continuously aerated and ventilated. The usual form of ventilation using windows usually doesn't provide a classroom with sufficient fresh air. Added to this, noise from the street, exhaust fumes, pollen and draughts may enter the room through open windows.
MAICO's KFD flat boxes are the optimum ventilation solution for classrooms. They quickly and easily provide the best room air quality!
To allow staff to work with concentration and breathe easy during their breaks, the staff room requires continuous ventilation, providing a supply of fresh and healthy air and reliably transporting used air outdoors.
The ESR sound-insulated ventilation box from MAICO is ideal for aerating and ventilating the staff room.
Vapours, odours and moisture are produced in school kitchens where cooking takes place in several areas at the same time. Grease and oil residue mix with the room air. This calls for a robust fan, which can quickly and reliably transport the used air outdoors and produce a pleasant room climate.
The ERR centrifugal duct fans are suited to ventilating school toilets. Fitted directly in the ventilation ducts, the ERR fans reliably ensure that odours and moisture are extracted as quickly as possible. Despite the toilets being used by large numbers of people, this produces a pleasant room climate.
Ventilation solution with heat recovery
A ventilation system with heat recovery function pays for itself twice over: you reduce your consumption of valuable resources and save on your energy costs!
MAICO's subsidiary AEREX provides a suitable unit for this scenario. The Reco-Boxx 1000 Flat heat recovery unit ensures that classrooms and staff rooms are continuously aerated and ventilated. More than 90 % of the heat already available is used. The heat from the exhaust air is transferred to the fresh supply air, so no energy is wasted. DC fans also ensure energy-efficient and therefore economical operation!
The Reco-Boxx 1000 Flat is fitted with G4 and F7 filters as standard, ensuring that pollen doesn't enter the room air. So allergy sufferers can breathe easy!
The Reco-Boxx 1000 Flat has a low total height of just 360 mm. This is particularly advantageous when space is tight, as is often the case during a redevelopment project. The unit can simply be mounted in suspended ceilings and is supplied ready for connection, along with a regulation unit.
Würzburg-Randersacker reference project
Scope of research project:
Number of pupils:
Fresh air requirement
A research project undertaken with ZAE Bayern (University of Würzburg) in collaboration with the medical school and other technical partners involved installing ventilation systems in 4 classrooms.
When the building was constructed in 1961, no attention was paid to the issue of thermal bridges. The school building was fitted with heat-insulating aluminium windows. Large amounts of mould have therefore formed in all 4 classrooms due to a lack of ventilation.
Pupils also experienced tiredness and poor concentration as a result.
Over a period of 2 years, the project aimed to investigate how installing a ventilation system impacts on the air quality in the classrooms and the well-being of the pupils.
More specifically, the following points were defined:
Following installation of the ventilation system and a two-year investigation, the following positive conclusion could be made:
Psychological examinations found:
Using sound-insulated window valves fitted with filters, fresh air permanently enters the classrooms. The used air is continuously extracted via valves in the exhaust air duct. The exhaust air ducts are installed on the ceiling of the side of the room opposite the windows. The box fans and sound absorbers are positioned in the corridor in front of the classrooms and/or in an adjacent room. This prevents potential noise issues. From there, the used air is conveyed outside via ventilation ducts.
