mixingventilatie

Mixingventilatie, also known as mixing ventilation, is a type of indoor air distribution system used primarily in thermal comfort and indoor air quality management. The system functions by mixing conditioned supply air with the existing room air to achieve a uniform temperature and contaminant concentration throughout the space.

In a typical mixing ventilation system, fresh outdoor air is supplied through diffusers or vents positioned in the ceiling or walls. This supply air is usually cooled or heated to reach the desired indoor temperature before entering the room. The supplied air then disperses into the space, mixing thoroughly with the room air to prevent stratification and ensure consistent temperature and air quality levels.

Mixing ventilation is widely used in commercial and institutional buildings due to its simplicity and cost-effectiveness. It effectively dilutes indoor pollutants and maintains thermal comfort when properly designed and balanced. However, its efficiency can be affected by factors such as occupancy levels, heat sources, and the layout of the space.

This system contrasts with displacement ventilation, which supplies air at low velocities near the floor to displace warmer, polluted air upwards, promoting stratification and cleaner zones near the occupants. Mixing ventilation is generally easier to install and adjust but may lead to higher energy consumption and less efficient pollutant removal compared to displacement systems.

Overall, mixing ventilation remains a common choice for maintaining indoor comfort, especially in spaces where simplicity and cost are prioritized. Proper design and operation are essential to maximize its effectiveness and minimize energy use.
