luchtdiffusers

Luchtdiffusers, or air diffusers, are components of heating, ventilation and air conditioning (HVAC) systems that introduce conditioned air into a space and promote mixing with room air. They are designed to control the direction, velocity, and spread of airflow to achieve thermal comfort and adequate air distribution, while minimizing drafts and noise. Diffusers are commonly installed in ceilings, walls, or floors and are selected based on space size, occupancy, and aesthetic considerations.

Common types include linear slot diffusers, perforated diffusers, round ceiling diffusers, and swirl diffusers. Linear slot diffusers provide a narrow, flat outlet for a diffuse yet directional air stream, while perforated diffusers spread air through a perforated face. Swirl diffusers create a helical jet that rapidly mixes with room air, and round diffusers are often used for ceiling installations with adjustable vanes. Floor diffusers deliver air at or near occupant level.

Performance is described by supply air flow rate, throw distance, velocity, pressure drop, and noise. Diffuser selection depends on room geometry, heat loads, occupancy, and ventilation strategy. Material choices include aluminum, steel, and coated metals, with finishes chosen for durability and aesthetics. Proper installation and maintenance ensure cleanability and efficiency, while proper balancing avoids drafts or short-circuiting of air.

Applications span commercial offices, healthcare facilities, schools, and laboratories. In standards, diffuser specifications are aligned with ASHRAE guidelines and local building codes to ensure adequate ventilation and comfort. Product databases provide performance curves and installation guidelines to aid engineers and facility managers.
