Design and manufacture of air supply system in dustless clean room

Apr 27, 2018

During the operation of the central air conditioning system in the clean room, we should check its temperature, humidity, positive pressure and filter to prevent the clean room without dust and clean room. At the same time, the air conditioning system should be cleaned and cleaned regularly. In addition, the noise reduction and vibration reduction of the air conditioning system should be carried out. The silencers set up should pay attention to the dust production and dust accumulation. To prevent vibration and noise from passing through the wind pipes and water pipes, and to meet the requirements of dustless clean rooms.

 

In order to realize the constant air supply of clean room, the pressure drop of the high efficiency filter and the air supply line can be borne by a typhoon machine. The other is responsible for the pressure drop of the initial and middle effect filters and the return air lines. At the same time, the air flow sensor is used to control the speed of the variable frequency fan to realize the constant air supply.

 

By controlling the speed of the variable frequency fan through the one or two return air flow sensor of the new wind to increase the dust of the high efficiency filter during the operation of the new return air ratio to the one or two return air, the resistance of the air supply is increased, and the speed of the frequency conversion fan is increased and the air pressure is added to keep the air supply constant.

 

In order to maintain the constant air supply in the clean and clean room, the return air quantity should be adjusted. When the pressure difference is higher than the set value, the new air volume is reduced and the return air is increased. On the contrary, the new air volume and the return air volume are increased and the new return air ratio is controlled. The fresh air volume, heat and moisture ratio, fan temperature rise and air supply state are known, and the one or two return air volume can be calculated and controlled.

 

When choosing materials for clean air cleaning systems of dustless clean rooms, it is recommended to choose materials that do not produce dust, are not easy to accumulate dust, and are easy to clean and wipe. The material of the pipe is usually made of high quality galvanized steel plate without obvious oxidation, pinholes, pitting and galvanized layer. After the production, the inner surface oil film and dirt are cleaned with no corrosion cleaning liquid. After the drying, the plastic film and tape are sealed to prevent the dust from entering.

 

In addition, the clean room wind pipe production is a very important process, after the cleaning of the wind pipe and parts before installation, do not dismantle the seal, install a port sealing film, immediately connect a good joint. In the installation process, we should not be too troublesome to ignore the closure of the mouth.http://www.wxrfcleanroom.com/
