Linear Diffusers In HVAC System

Diffusers

HVAC diffusers are outlet vent points on heating ventilation and air conditioning (HVAC) systems. Diffusers are occasionally used as return air vents, the main purpose is to introduce conditioned air into a space in such a way to achieve mixing and distribution with minimum noise. HVAC diffusers are produced in a variety of standardized sizes and are generally square, rectangular or round; they typically feature sets of fins that direct air flow in a preset pattern. Larger, industrial diffusers may include adjustable louvers or dampers, which can be manually or automatically adjusted to control airflow volumes. Also, diffusers play an essential role in the efficacy of HVAC systems.

Installers fasten the linear diffuser into a ceiling, wall, or window sill area so that the louvered face sits flush with the surrounding surface. Linear diffusers work with both drywall structures and drop ceilings, but different types of models may be required to fit different applications. The most common linear diffuser designs include rows of diffusers along an entire wall, with vents placed either in the ceiling or window sills.

Traditional supply vents feature a very large, rounded design. The entire air contents of each supply duct were forced out of a single vent, creating drafts and noisy conditions. While, with linear diffusers, the supply air is distributed through a narrow channels so that it enters the room in several different areas at once. This creates a much more distribution of air, as well as improved comfort and quieter ventilation.

Engineers and installers must select each linear diffuser carefully to maximize air flow and ensure a comfortable, healthy building. The fins or slots on each unit may face different directions, which determines which way the air can flow from each vent. The angle and size of each of these slots must match the size of the HVAC system, as well as the required airflow for the building. The size and configuration of each vent also effects noise levels and the speed at which the air can

These types of diffusers are made out of metal or wood, but there are many designs for the shape and orientation of the slats that cover the opening of the diffusers. In some cases, the direction in which these slats send the air can be adjusted with built-in hinges. However, the slats that cover the face of a baseboard diffuser are stationary.

The most basic functions of a baseboard diffuser are to fit snugly within the opening of a wall vent and to direct the flow of air in the appropriate direction or directions. Choosing the right size is often rather simple, as there are standard sizes for vents and vent openings. Just be sure to take accurate measurements and check to make sure that all of the baseboard vents are the same size. In order to make sure that the air flow from the vents is maximized, make sure that the slats in the diffuser point in a few different directions. This will cause the air to diffuse out into the room instead of simply pouring in from one
