Cleanroom simulation

TRADELABOR has more than 20 years of experience in the control and treatment of air, working with an experienced and qualified technical staff and with the most advanced technology in this area, which together guarantee the quality of the services provided.

 

 

In general, is the particle contamination in a cleanroom to be held under the allowed values to protect the products and processes against influences of the “normal” environment. Special principles of cleanroom technology are applied in such cleanrooms. This includes a low-turbulent displacement flow with a (normally multilevel) filtering and high air throughput.

Aim of an analysis of the cleanroom conditions is to ensure the purity of the air in the entire room. Potential contamination sources need to be identified and the direct discharge of the air contamination out off the cleanroom has to be ensured. On the other hand, ventilation equipment and device arrange- ment within the clean room have to be optimised in that way to obey beside the cleanliness also the comfort requirements regarding air temperature and velocity.

Method – The cleanroom simulation is an important tool to support the extensive process of flow analysis and qualification of a cleanroom approval. The clean room is simulated with  a three-dimensional computer model considered furnishing, ventilation equipment, heat and particle sources. The calculations are performed under consideration of special models to account for turbulent flow and buoyancy effects.

Results – The simulations allow the three-dimensional visualisation of velocity and temperature fields, particle concentrations, pressure distributions as well as particle paths. Detailed analyses of transient and location-depending processes within the cleanroom lust like virtual tests (for instance the recovery test) can be simulated before an actual cleanroom qualification.
Compared to flow measurements in the cleanroom, numerical simulation models have a clear advantage. They can visualise flow conditions and contamination conditions already in the design phase of a clean room and are, therefore, far more effective when applied already in the planning phase.
