Definition of clean room

Clean room defines clean room, also known as dust free workshop or clean room. Clean room refers to a specially designed room that eliminates the pollutants such as particles, harmful air and bacteria in the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, lighting and static electricity within a certain demand range. That is, no matter how the external air conditions change, the indoor can maintain the performance characteristics such as cleanliness, temperature, humidity and pressure originally set.

Purification principle
 
Airflow - primary purification - air conditioning - medium efficiency purification - fan air supply - Pipeline - high efficiency purification outlet - blowing into the room - taking away particles such as dust and bacteria - return air shutter - primary purification.
 
Repeat the above process to achieve the purpose of purification.
 
Purification parameters and ventilation times:
 
Not less than 100000 times;
 
Not less than 20 times for 10000 levels;
 
1000 not less than 30 times.
 
Differential pressure: the pressure between the main workshop and adjacent rooms shall not be less than 5pa
 
Average wind speed: Grade 10, Grade 100, 0.3-0.5m/s;
 
The temperature is greater than 16 "C in winter; less than 26c in summer; fluctuation ± 2'c.
 
Humidity 45 - 65%;
 
The humidity of GMP powder workshop should be about 50%;
 
The humidity of the electronic workshop is slightly higher to avoid static electricity.
 
The noise shall not be greater than 65dB (a);
 
The make-up volume of fresh air is 10% - 30% of the total air supply volume;
 
Illumination 300lx.
