The hvac design is driven by the cleanliness of the room iso class but also by the required temperature humidity and pressure differential.
Clean room design.
The space cleanliness classification is the primary variable in determining a cleanroom s supply airflow.
For example a class 100 000 cleanroom has a 15 to 30 ach range.
Clean room design also known as the chinese wall technique is the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights associated with the original design.
Looking at table 3 each clean classification has an air change rate.
Clean room design encompasses much more than traditional temperature and humidity control.
These prescribed conditions are dictated by the process involved in the cleanroom and the comfort of the personnel working inside the room.
However because independent invention is not a defense against patents clean room designs typically cannot be used to circumvent patent restrictions.
Many manufacturing processes need the very stringent environmental conditions provided by a cleanroom.
Design must consider aspects such as control of particulate microbial electrostatic discharge gaseous contaminants airflow pattern control and pressurization and industrial engineering aspects.
Clean room design is useful as a defense against copyright infringement because it relies on independent creation.
