1- 100 class clean room, organizations are using the one-way flow of air supply, clean indoor air that same section at any point, airflow direction and speed are consistent, This allows clean room air like “piston ", as indoor dust particles fastest away. To achieve the “piston " effect, HEPA filter needs full covered of room ceiling can be achieved only charge a one-way direction of airflow.

Non- unidirectional airflow (1000-100.000 class) clean room:
1000- 100.000 class airflow direction is different with above 100class clean room, indoor air is uneven parallel flow velocity was not accompanied by reflow or vortex , which mainly depends on the continuous flow of clean indoor air dilution , will gradually discharge DC high voltage generator indoor pollution , to achieve purification . achieve different purification level, mainly by the amount of air per unit time to the performance of the different.

Optical Products Clean room--LED Industrial Cleanroom Project

Optical Products clean room generally applicable to electronic instrumentation, computer, semiconductor plants, automotive, aerospace industry, lithography, micro machine manufacturing and other industries , in addition to air clean class level, but also to guarantee the achievement in addition to static requirements. The following represent the most modern LED industry as an example, photoelectric optical industry clean purification plant
LED purification plant engineering installation and construction Case Study: In this design, there is the end of some of the purification process of installing clean room, its purification cleanliness is generally one thousand or ten thousand or a hundred thousand grade purification clean room installation.

Backlit screen class cleanroom installation of these products are mainly press shop, assembly purification clean room, its cleanliness is generally ten thousand or one hundred thousand purification clean room.

LED indoor air clean room installation parameters required :
    1 ) Temperature and humidity requirements: temperature is generally 24 +2
, relative humidity of 55 +5%.
    2)  Large fresh air. As these purification clean room most are personnel, you can take the following should be the maximum value according to the following values: non- unidirectional flow clean room workshop purify total air volume 10-30 %; compensation indoor ventilation and keep the interior positive the amount of fresh air required pressure value; ensure indoor fresh air per person per hour of ≥ 40m3 / h.

   3)  Air volume supply. In order to meet the clean class level, the heat and humidity balance within the clean purification plant, require a larger air volume, on 300 square meters of workshops , ceiling height of 2.5 meters , if it is thousand grade purification clean room, air volume on need 300 × 2.5 × 30 = 22500m3 / h of air volume ( ACH is ≥ 25 times / h); If you are one hundred thousand purification clean room, air volume you need 300 × 2.5 × 20 = 15000m3 / h of air volume ( ventilation frequency is ≥ 15 times / h).
