plafonddiffusers

Plafonddiffusers, or ceiling diffusers, are components installed in the ceiling of indoor spaces to distribute conditioned air from heating, ventilation, and air conditioning (HVAC) systems. They function to deliver air into a room with a controlled pattern, contributing to thermal comfort, indoor air quality, and energy efficiency. Ceiling diffusers come in a range of shapes and configurations and are typically used as supply outlets.

Common configurations include round, square, and rectangular diffusers, as well as linear slot diffusers. Diffusers may incorporate adjustable vanes or blades to steer the air and create forward jets, broad mixing patterns, or diffuse, gentle airflows. Perforated and lattice-style diffusers provide diffused air distribution with lower potential for drafts, while circular and square models often serve higher-velocity or targeted delivery. Some ceiling diffusers are designed to be used in conjunction with acoustic or lighting elements.

Design considerations include ceiling height, room use, occupancy, heat gains or losses, and noise criteria. The goal is to achieve uniform temperature distribution and minimize drafts and stratification while supporting energy-efficient operation. Material choices typically include aluminum or steel, with finishes that suit the interior and may include integrated acoustic or lighting features. Installation is often in suspended ceilings and may be combined with ceiling tiles.

Applications span commercial offices, retail spaces, healthcare facilities, and hospitality environments. Plafonddiffusers are often specified to meet local standards on ventilation, acoustics, and energy performance, and are selected based on desired air patterns, maintenance needs, and aesthetic integration with interior design.
