There are many benefits to installing fresh air dampers in a building's ventilation system. Dampers can help regulate the amount of fresh air entering a building and help maintain indoor air quality. Fresh air dampers can also help reduce the amount of energy used to heat and cool the air in a building because they help keep the air at a constant temperature.

BIG5 is the largest trade fair for the construction industry in the Middle East, Africa, and South Asia. It is considered a global reference point for companies involved directly or indirectly in the construction industry.

How many types of HVAC diffusers and dampers we have? As far as we know, the diffuser and the grille are used at the end of the entire HVAC system. It is not only an air outlet that can supply and return air which provides fresh air for the areas but also has the function of installation. We can see all kinds of air outlets on the ceiling in the commercial center, they have square, round, rectangle, and linear slots. And there are also very important components on this diffuser and grille, it as a damper.

The HVAC damper is a component in charge of controlling the airflow in an HVAC system. It helps to adjust your room temperature. It could be compared to a faucet switch, when a damper is closed, it stops the water from coming out. For the same reason, when you close the damper, the airflow can not come in or come out.

1. Type and setting of the air outlet ① The form of natural ventilation air supply and exhaust outlet shall meet the requirements of cross ventilation.

A ceiling diffuser is a type of vent cover that is installed over vent opening in the ceiling, it directs the air from air conditioning systems into the room. The role is to supply conditioned air into the space. After the air is processed through the heating and cooling system, it is funneled through the ductwork until it reaches the ceiling diffuser.

​HVAC diffuser is very common in heating, ventilating, and air conditioning systems. They are used on both all air and air water HVAC systems. It delivers both conditioning and ventilating air. Evenly distribute the flow of air in the desired directions. To enhance the mixing of room air into the primary air being discharged. And create low velocity air movement in the occupied portion of the room.

​Today we will talk about how to select the air outlet after the installation of the internal and external units of the central air conditioner.

​The HVAC diffusers shall be customized according to the opening size. In order to facilitate installation, the actual inner diameter (length and width) of the HVAC diffusers will be slightly less than the net opening size by 0.5-1.0 cm.

An HVAC diffuser is widely used to disperse the air from a heating, ventilation, and air conditioning system. The diffuser is in the right direction while providing a decorative cover for the vent. For the air diffuser and grille, you can regulate the air pressure and choose the direction where you want the airflow, it can be wall-mounted or ceiling based and may offer multi-directional airflow.

​The HVAC system is a heating, ventilation, and air-conditioning system. It often utilizes air duct systems throughout homes and commercial buildings. The air diffusion system is designed to eliminate the need for traditional ductwork by providing a single air diffuser or grille to supply and return air to each rooftop.

When we need to buy or change a new air terminal unit, we are facing differences in the name of the air terminal unit: air diffuser and air grille HVAC. So what’s the difference between them? Do they look the same? Okay, let’s get started now!

The temperature displayed on the air conditioner generally refers to the set target temperature, that is, the desired indoor temperature, not the current indoor temperature. When the temperature is 26°C in winter, the indoor temperature does not reach 26°C. In the heating mode, the air conditioner will stop heating when the indoor temperature reaches the set temperature; if the current indoor temperature is higher than the set target temperature, the air conditioner will also stop heating.
