dyfuzor

Dyfuzor, or diffuser, is a device designed to spread a substance or energy more evenly within a space or along a path. The term is used across industries to describe such spreading, and diffusion is the underlying mechanism.

In heating, ventilation and air conditioning, air diffusers introduce conditioned air into rooms. They control velocity and direction to promote mixing and reduce drafts.

In acoustics, diffusers scatter sound waves to reduce unwanted reflections and create a more even reverberation. Common designs include quadratic residue diffusers (QRD) and skyline diffusers, which are installed on walls or ceilings to improve room acoustics.

In lighting, a diffuser softens illumination by spreading light from a source, reducing glare and harsh shadows. Materials used include frosted glass, acrylic, or polymer films, and diffusers are common in photography, stage lighting, and architectural applications.

In automotive design, a diffuser is a shaped surface at the rear underbody that accelerates air flow and reduces turbulence, contributing to downforce and lower drag at speed. Diffuser geometry and mounting influence performance and stability.

Diffusers are also used for fragrance and humidification, with aroma diffusers releasing essential oils into the air, and nebulizing or evaporative diffusers handling moisture and scent diffusion. In spray and irrigation systems, diffusers help distribute liquids more uniformly across a target area.

Safety, maintenance, and material choices vary by application, with considerations including cleaning, compatibility with fluids or oils, and the effects of diffusion on system performance.
