HVAC Diffuser: The Ultimate FAQ Guide
What is HVAC Diffuser?
An HVAC diffuser is a device that is used to change the HVAC system’s fluid velocity and static pressure.
HVAC diffusers is an indispensable part of the air delivery and distributions in the whole HVAC system.
In all, there are grilles, registers, and diffusers.
What is VCD Diffuser?
Volume Control Damper Diffusers are oneswith damper at the back whose fuction is to control the air volume flowing through HVAC system.
How does an HVAC Diffuser Work?
HVAC diffuser consists of dampers, which reduce the velocity of air as it flows through.
As air flows through the HVAC diffuser, it slows down, thereby increasing the pressure within the diffuser.
This pressure then gets the air while mixing with the surrounding before flowing into the room.
You can control the dampers to regulate the amount of air flowing into the room.
This, in turn, has the effect of controlling the level of pressure and the amount of heat.
What is HVAC Air Balancing?
Air balancing is the act of testing and adjusting the airflow of your air conditioning system to achieve the desired air volume.
We use an air balancing hood to measure air volume in each grille, a manometer to measure the system pressure and a hygrometer to measure the humidity and temperature of your system.
What is the Difference between Grille, Register, and Diffuser in HVAC Systems?
A grille refers to a device whose function is to extract and supply air vertically without any deflection.
A register is a special type of grille that has moving parts.
Basically, they consist of grilles and dampers.
They usually are placed where there are air flow openings in your ventilation system.
There function is to control the volume and direction of air flowing into your room.
On the other hand, a diffuser is a device that helps in minimizing the speed while increasing the fluid’s static pressure as it flows along with the HVAC system.
The neck size and air flow size are normally different.
In addition, with diffuser, the air often makes a direction change from the ducting.
HVAC Diffuser vs. Register, How do they Compare?
You can easily adjust, open or close in between HVAC registers.
HVAC register consists of fins that help in channeling the flow of air towards a room while diffusers consist of dampers.
Diffusers help in controlling the volume of air flowing into a room while a register helps in controlling the direction of airflow.
