Linear diffusers play an important role in ventilation and air conditioning systems, and their optimal selection and arrangement directly affect the efficiency of air distribution in rooms. In this publication, we will explain how to effectively model air distribution in ventilation systems using linear diffusers.

Why is effective air distribution important?
Effective air distribution in a room (regardless of its purpose) ensures comfort for users and also improves the energy efficiency of the entire ventilation and air conditioning system.
Properly performed ventilation – benefits :
- Reduction of air pollution , which has a positive impact on the well-being and health of people staying in ventilated rooms .
- Maintaining optimal humidity and temperature prevents drafts and ensures thermal comfort.
- Elimination of the risk of creating zones with excessive air flow , where excessive cooling should not occur, and the installation itself does not exceed the permissible sound level (work room - 85 decibels should not be exceeded).
The correct location of air vents should be carefully planned to limit unfavourable factors to the necessary minimum , such as uneven temperature distribution or excessive air movement in places where it may cause discomfort.
Additionally, in the process of improving air quality and its reuse, appropriately selected ducts and heat recovery are of great importance, the use of which ensures the supply of warm air and also reduces heating bills.
Also important are the parameters characterizing the air vents, the system of which is responsible for the distribution of fresh air , and consequently low humidity and optimal thermal conditions. At the end of the ventilation duct, which is located in the room, a high-quality supply air valve is mounted.
It is important to select appropriate devices for the characteristics of a given location and type of installation.
What data should be taken into account when selecting a supply air supply?
When designing a ventilation or air conditioning system based on linear air vents, several technical parameters should be taken into account that will influence the distribution of air in the room.
The most important data include:
- Supply air flow – must be adapted to the size of the room and the number of people inside.
-
The range of the supply air flow – depending on the location of the air inlets and their number, it is necessary to assess how far the air flow will spread. Inappropriate configuration of exhaust systems can lead to the creation of dead zones or drafts . - Correct location of air vents – air vents must be placed in places that will ensure even air distribution without creating zones of perceived discomfort.
- Exceeded sound levels – incorrect selection of air vents or excessive air flow may lead to the generation of noise above permissible standards, which negatively affects user comfort.
Each time, slot air vents should be selected that are designed for quiet operation and even air distribution in rooms of different sizes and purposes.
Calculation of air distribution using linear air diffusers
Modeling air distribution using linear diffusers is a process that requires taking into account many technical and environmental aspects.
Four basic factors to consider:
- Determining the demand for fresh air in a given room , which depends on its area, number of users and specific needs (e.g. humidity or removal of pollutants).
-
Adjusting the air supply vent parameters – it is important that the parameters characterizing the air supply vents correspond to the assumptions of the installation design. The vents should be selected so as to provide the appropriate flow with the lowest possible resistance. - Optimization of the location of air inlets – at the stage of designing the ventilation system , it is necessary to precisely determine the places where the air inlets will be installed. The process of designing the ventilation system requires taking into account whether the air flow is located at strategic points, ensuring even distribution of air throughout the room . This depends, among other things, on the arrangement of air inlets at strategic points.
- Monitor and calibrate your system – after installation, it is important to monitor system performance and make any necessary adjustments to optimize flow and maintain proper temperature levels.
In the Onninen wholesaler you can find a range of products for precise control of air distribution in ventilation systems. An example are supply air diffusers with speed and flow direction regulation recommended by specialists. The use of this type of diffuser helps to adjust the air stream to the specific needs of the rooms .
Effective modeling of air distribution in rooms using a linear air supply vent requires taking into account many parameters , such as the supply air flow , the range of the stream and the correct location of the air supply vents .
