The space cleanliness classification is the primary variable in determining a cleanroom s supply airflow.
Clean room design.
Clean room design is useful as a defense against copyright infringement because it relies on independent creation.
However because independent invention is not a defense against patents clean room designs typically cannot be used to circumvent patent restrictions.
These prescribed conditions are dictated by the process involved in the cleanroom and the comfort of the personnel working inside the room.
Clean room design encompasses much more than traditional temperature and humidity control.
The hvac design is driven by the cleanliness of the room iso class but also by the required temperature humidity and pressure differential.
Many manufacturing processes need the very stringent environmental conditions provided by a cleanroom.
Looking at table 3 each clean classification has an air change rate.
Because cleanrooms have complex mechanical systems and high construction operating and energy costs it is important to perform the cleanroom design in a methodical way.
For example a class 100 000 cleanroom has a 15 to 30 ach range.
The cleanroom s air change rate should take the anticipated activity within the cleanroom into account.
