Clean Room Design
Many manufacturing processes need the very stringent environmental conditions provided by a cleanroom.
Clean room design. 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. Looking at table 3 each clean classification has an air change rate. The hvac design is driven by the cleanliness of the room iso class but also by the required temperature humidity and pressure differential.
The space cleanliness classification is the primary variable in determining a cleanroom s supply airflow. Design must consider aspects such as control of particulate microbial electrostatic discharge gaseous contaminants airflow pattern control and pressurization and industrial engineering aspects. 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. The cleanroom s air change rate should take the anticipated activity within the cleanroom into account.
Clean room design encompasses much more than traditional temperature and humidity control. 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.
