Ventilation grilles are the terminal elements located in the rooms and that serve to admit or extract air, and may be located in duct networks or in direct openings to the outside or other premises. These elements have a functionality that is not only physical protection, preventing access to the duct or opening, but must also provide the best possible distribution or collection of air. Updated on November 7, 2023. The grids have objectives that are contradictory in many aspects, so a compromise solution must be sought that guarantees adequate behavior. In the case of air supply grilles, they must have, among others, the following characteristics: low pressure loss through them good air distribution system in the room low acoustic impact low or no presence of vibrations ease of maintenance and cleaning The air expelled into the room must be distributed as homogeneously as possible and avoid the formation of areas that are without ventilation, which is why the design of the slats is key to achieving adequate operation. Furthermore, the air, although it must be distributed as best as possible, cannot be propelled at excessive speeds that cause problems and discomfort to the building's users.
The aerodynamic profiles used allow a compromise solution to be found between air distribution, speed and acoustic level. High air velocity, for example by using very small sections compared to the previous ones, allows the air to be better distributed throughout the room, but can cause noise or vibration problems. Given that the grilles are the final element of the installation and that is why they are located in different rooms, a design must be Lithuania WhatsApp Number List sought that allows simple visual integration with the environment, for which they are designed with multiple finishes, shapes, profiles, materials and colors. Its manufacturing material can be metal (generally aluminum) or plastics. Depending on the type of ventilation system chosen, we will have more or fewer ventilation grilles in the home, this being a key aspect when it comes to achieving good architectural integration. Ventilation grille - S&P Types of ventilation grilles and their uses Analyzing the typology of grilles for the different ventilation systems most commonly used we will have: Single flow ventilation In this case, the extraction is carried out through a duct and the air intake is produced by infiltration, using the small fissures and non-watertight elements of the building, and grilles, normally located above the windows.
These grilles do not have any type of conduit or mechanical drive connected, but rather they directly communicate with the outside of the building. The air is distributed internally in the home, from the entrance rooms (dry) until reaching the extraction area, in bathrooms and kitchens, through ducting. It is in this area where we will have a grille for each opening, for the final extraction of air. These are usually circular in section and are designed to minimize the visual impact in bathrooms or kitchens. It is important to mention that inside the home there may be grilles that allow adequate air circulation between the air intake (dry) rooms and the extraction rooms, usually located in the doors. Dual flow ventilation In these systems, air is supplied through a duct to the rooms, which means that there is an intake grille in them, normally located on the ceilings or walls. These grilles can be low profile and have multiple finishes, facilitating placement and integration in each room. These grilles also have the aerodynamic function of achieving very good air diffusion throughout the room, avoiding the presence of dead or shadow areas, which would have a lower air supply than required or even none at all.
