From August 17th to August 19th, 2022, our company VENTECH had an annual trip in Huizhou shuangyue Bay.
On the afternoon of August 17th, we arrived in Huizhou. After checking in the hotel, we started our free trip.

With the continuous improvement of our country's economic level, people's living standards are also rising year by year. At the same time, the status of our country's ventilation and air-conditioning projects in our country's construction industry is gradually increasing.

Are you still cutting air ducts by hand tools? Do you agree it is time-consuming, costy on labour, material wasting? Do you know that your competitors are already using air duct cutting machine and be way ahead of you?

1.Basic Concept of Clean Air Conditioning
Clean air conditioning is a kind of air conditioning engineering. It not only has certain requirements on the temperature, humidity and wind speed of the indoor air, but also has higher requirements on the number of dust particles in the air and the concentration of bacteria.

Galvanized duct, whether insulated or uninsulated, are designed for air conduction, renovation and return air of air conditioning equipment.

According to Wikipedia, CNC router is short for computer numerical control router. It is a computer-controlled cutting machine which typically mounts a hand-held router as a spindle.

At present, it is essential that any industrial ventilation process has an adequate automation system in order to guarantee optimal operating conditions.

1. Process flow of closed-cell rubber-plastic sponge insulation
(1) First, wipe the surface of the air duct clean, wipe off the dust and accumulated water on the surface and let it dry.
(2) Cut the insulation material according to the size of the air duct.

The word “CNC” is short for Computer Numerical Controlled, which refers to the programmable feature of the machine. CNC machines can perform many functions with minimal human control. CNC machining refers to a range of subtractive manufacturing processes.

The term HVAC (heating, ventilation and air conditioning) ductwork describes any ductwork and vent system used to direct and distribute air in a vehicle or structure. HVAC ductwork is used in a variety of spaces from automobiles to homes to the largest construction sites, but all systems share certain characteristics in that they provide air circulation.

The tightness of the air duct is an important quality indicator for the construction of ventilation and air conditioning projects. The method of testing this quality item can use light leakage detection or air leakage test.

The composite air duct is made of a variety of mixed materials, including phenolic, glass magnesium and other air ducts. Composite air duct is a new generation of environmentally friendly and energy-saving air ducts that replace iron sheet air ducts and glass fiber air ducts. The composite air duct product is made of two layers of high-strength inorganic materials and one layer of thermal insulation material as the base material, and adopts adhesive technology and special structural combination
