1.Compression air conditioning refrigeration
When the air conditioner is in cooling operation, the low-temperature and low-pressure refrigerant gas is inhaled by the compressor and then pressurized into a high-temperature and high-pressure refrigerant gas.

1.How to choose a fan coil unit?
The fan coil unit has two main parameters: cooling (heat) volume and air supply volume, so there are two ways to choose:

CNC routers normally have 4 major parts, controller, cutting bed, spindle, drive system. The controller is the brain of the CNC router, it sends signals to the arms and tells them which direction to move the spindle.

First, find out the elevation of the air duct according to the design requirements and with reference to the civil construction datum line.

The CLIMAVER duct This company is the main representative and distributor of the international Pre-insulated duct market. This panel has a unique housing with marked guidelines, which helps cut and eliminates the risk of drawing errors.

In the industry, "HVAC" is generally used to refer to air conditioners with heating, ventilation and air conditioning functions, which is an important part of building functions, which means that it is difficult for us to live without it.

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.
