How to choose your Air Handling Unit (AHU)?
Because each project and
each use is unique
our experts will help you define your needs and choose the solution best suited to your activity, right up to the installation and maintenance of your model.
managing air quality
of your premises and tertiary buildings, it is first necessary to evaluate the various sources of pollution, intrinsic as extrinsic:
Whether you are hosting employees and/or the public, you should consider several criteria, including:
- Water vapour emissions, generated by human activities (breathing, cooking, toilets, etc.) and likely to cause humidity problems and a feeling of discomfort within your premises. Did you know that a single person gives off at least forty grams of water vapor per hour?
- Body odor, which can stagnate and create a form of olfactory discomfort.
- Carbon dioxide, whose high level can affect health (migraines, nausea, choking sensation, etc.). To give you an idea, a single person in a sitting position emits an average of eighteen liters of CO2 per hour.
- The nature of the activities inside the buildings (tobacco smoke, industrial dust concentration, toxic gases, carbon monoxide, etc.).
- Types of building materials used (formaldehyde, volatile organic compounds, solid particles, etc.).
- Other external sources (traffic pollutants, ozone, pollens, viruses, radon, etc.).
Faced with these multiple sources of pollution, it is necessary to ensure the proper management of air quality. To avoid health problems, discomfort and the risk of deterioration of the building, favour a collective ventilation system capable of diluting and evacuating the pollutants emitted in the premises to a level deemed acceptable.
A collective and tertiary CMV is composed of a roof extractor or a ventilation box, connected to one or several ducts equipped with ventilation outlets. The latter will serve the wet rooms, such as the sanitary facilities for example. The power of the ventilation must be adjusted according to the rhythm and lifestyle of the occupants.
Several types of collective and tertiary CMV
The market offers:
- The single flow tertiary CMV;
- The tertiary double flow CMV;
- The collective ventilation box ;
- The industrial air extractor (or VMC by industrial extraction).
The Air Handling Unit (AHU) with thermodynamic recovery
Among the collective CMV systems adapted to the tertiary sector, we find the
Air handling unit (AHU) with thermodynamic recovery
. As its name indicates, it aims at receiving and treating the air which will be blown towards the premises needing to be air-conditioned, thanks to a specific ducting.
If a ventilation system that is too old can cause significant heat loss, installing a thermodynamic AHU has several advantages:
- To ensure the renewal ofthe air at all points of the premises;
- To vary the quantity of extracted and blown air, thanks to a variable static pressure;
- To recover the calories (or frigories) of the air extracted by aspiration in order to reinject them in the premises by insufflation
(double flow CMV system
- Benefit from a fresh air filtration system, essential when there is a high risk of pollution of the atmosphere;
- Monitor and regulate temperature and humidity (hygrometry).
Choosing the right ventilation system for workplaces and public areas
This is therefore essential. Complementary to efficient heating and insulation, MyDATEC’s ventilation solutions, such as the thermodynamic AHU, allow you to control the air flow necessary for good air quality.
MyDATEC offers a wide range of individual and collective ventilation systems. Find our numerous products and accessories (ductwork, ducts, fittings, air inlets, etc.) for the commercial and industrial sectors. If you would like to know more about our solutions and
