​In modern buildings, central air conditioning has become very common, and ventilation ducts are an important part of the central air conditioning system. According to statistics, the annual demand in my country is about 100 million square meters, reaching 20 billion yuan.

A diffuser is a device that is used to change the velocity and increase the static pressure of a fluid passing the HVAC system. The fluid's static pressure rise as it passes through a duct is commonly referred to as pressure recovery.

​The proposal of the self-vertical leaf of the hvac diffuser is to open a one-way vent, and when there is an air outlet, the external exhaust vent is automatically opened, and there is no wind-stop ventilation in the room.

As the manufacturer of HVAC products, VENTECH producing a series of HVAC accessories such as air diffuser and air grille, etc.

An HVAC air vent diffuser is a simple vent that is widely used for ventilation, heating, and air conditioning HVAC units. They are mainly installed on high ceilings, walls, or floors so that the air coming from HVAC systems can be dispersed evenly throughout the room or desired area. Although it is widely used for enhanced air blowing in the room, it also helps to reduce noise and can improve the effectiveness and efficiency of your HVAC unit. Some people also use the hvac diffuser as return air vents.

​Step 1: Determine the central air conditioner model First of all, consider the area and orientation of the house to see if there are large glass windows, so as to calculate the maximum simultaneous use coefficient of air conditioning.

The round ceiling air diffuser is the air supply outlet of air conditioning or ventilation, which is to divide the air outlet direction into multi-directional flows. It is generally used in the air supply outlets of large areas such as the hall, so that the fresh air is evenly distributed.

​The rotary jet is sent out, which has the characteristics of a large induction ratio and fast wind speed attenuation. It can be used for large air volumes and large temperature differences in air conditioning and ventilation systems to reduce the number of air outlets.

​When the area of public places such as various halls and assembly workshops is large, the ceiling air supply outlet can not send air evenly or achieve the effect, in this case, it is necessary to install nozzles to supply air at the side. When the temperature difference between the supply air and the room temperature is constantly changing, the supply air flow will shift upward (hot air) or downward (cold air). The air supply direction may also be disturbed by external factors, such as local air flow or lateral air flow. The jet nozzle diffuser is designed to be rotated, and the direction of the air supply can be manually adjusted on the spot. It can swing through the actuator within the range of plus or minus 30 degrees. Pneumatic or electric actuators can also be provided as required. Specifications and models can be selected from 100mm to 630mm and other specifications and sizes.

We recently secured a complete HVAC project in Chongqing, a new kindergarten school. Includes central air conditioner, air diffuser and phenolic duct installation.This is the second big project we got in Chongqing this year! ! Really appreciate that our customers for their choice and trust.

In order to well know more about HVAC diffuser, first, we need to know something about the HVAC systems.

Natural ventilation with multi-blades supply air grille is a key step of indoor air conditioning, which can directly harm the actual effect of air conditioning units. The central air conditioner room shall be equipped with exhaust, air supply, and exhaust systems. The natural ventilation shall ensure that there is no blind area of the swirling air outlet in the room.

The main performance indicators of the aluminum ceiling diffuser are additional exhaust air volume, inlet, and outlet negative pressure, input power, additional cooling capacity, additional heating capacity, noise, liquid resistance, etc. With regard to the double control water management system, the aluminum ceiling diffuser is applicable to the air duct of the central air conditioning system that only performs heating or cooling conversion according to the season or the central air conditioning area.

VENTECH is the leading manufacturer that specially produces aluminum diffusers and grilles, air louvers, volume control dampers and other HVAC accessories items.

The coating of the secondary air oxidation surface layer of the aluminum alloy air terminal unit is constructed of all aluminum alloy profiles and is defined by stainless steel plates when the light source enters into different transport chemical substances. The electric welding thick steel plate material with hot-dip or cold treatment layer on the surface layer is waterproof, rainproof and fireproof.
