What is an air supply register?

WHAT IS AN AIR REGISTER? Air registers are essential mechanical components to a building’s HVAC (heating, ventilation, air cooling) system. They cover a hole in the wall, floor or ceiling where the air duct enters the room. Their main function is to supply air.

What does a supply register do?

A well-placed supply register delivering 100 cubic feet per minute of airflow can easily condition 1,000 to 2,000 cubic feet of room air. The principle behind this is that higher velocity supply air coming out of the register entrains the air of the room and mixes these two bodies of air together.

What’s the difference between a register and a grille?

In simple terms, an air register is the same as a grille, but with adjustable dampers in it. Unlike grilles, which can be for both intake and release of air in a room, a register only serves the latter. An air register usually is used with air supply outlets feeding air into indoor spaces.

Where do I put my HVAC register?

Supply register vents should be in every room as well. Located on the outer walls, under windows, in the ceiling, or on the floor, placement depends on the heating or cooling system as well as the construction of the home. Supply vents help change the room temperature to your desired heat or cool setting.

What is supply and return in HVAC?

Supply vents are usually found high up on the walls in your home, or on the ceiling. Return Vents: These air vents suck air from the rooms in your home back into your HVAC system. They are typically larger in size than supply vents and you will not feel air blowing out of them.

What is a supply vent?

Supply vents: These are the vents that blow air into each room. The conditioned air goes from your air conditioner or furnace, travels through the ductwork and exits out the supply vents. These vents are easy to identify, as they’re the only vents from which you can feel conditioned air blowing out.

What is the difference between register and diffuser?

Grilles – Remove air from an indoor space and return it to the HVAC system for reconditioning. Registers – Supply conditioned air into an indoor environment. Diffusers – Push conditioned air into a space in a set pattern for optimal airflow distribution.

What is a supply grille?

A supply grille covers the supply vents that are responsible for pumping air into a room. Supply grilles are available with a louver or damper to control air flow, or as an immobile vent cover.

Where should supply registers be located?

Supply Registers Supply register vents should be in every room as well. Located on the outer walls, under windows, in the ceiling, or on the floor, placement depends on the heating or cooling system as well as the construction of the home.

Does every room need a supply vent?

While it is a myth that air return grilles are required in each and every room in the house, it is definitely necessary to have more than one of these grilles installed at strategic places in the house. The most important place to have these would be the bedroom.

What is a supply diffuser?

In HVAC systems, the air supply diffuser is a device that delivers and ventilates conditioned air in an area, mixes indoor air, and manages air output. It works by reducing the air duct velocity by increasing the static pressure. << Return to Glossary.

What is a return register?

What is a Return Register? Often referred to as high/low vents, ducts, and grilles, return registers are pairs of registers located near the ceiling and floor of rooms throughout your home.
