Study of a clean room
Optimization of energy consumption in cleanrooms
EOLIOS Engineering provided an overview of the conditions in a cleanroom when reducing the ventilation rate of sterile air.
Description of the mission
Why perform a CFD simulation of a cleanroom?
Cleanrooms are an essential element in many industries, from pharmaceuticals to aerospace manufacturing. CFD simulations are a powerful tool that can help design and optimize cleanroom performance, allowing engineers to predict environmental parameters and identify areas for improvement. By running a CFD simulation of a cleanroom, engineers can gain insight into airflow patterns and temperature distribution in the space, allowing them to make informed decisions on how best to improve cleanroom performance.
Aerodynamic engineering for the pharmaceutical industry:
A pharmaceutical company that produces drugs in
asked Eolios Engineering to provide information on the conditions in a cleanroom when reducing the ventilation rate of sterile air.
The ultimate goal was to reduce the throughput, and thus the energy costs (cooling, heating and energy of the fans), while the conditions of the clean room had to remain within the given limit values.
EOLIOS modeled the clean room by adding internal sources of pollution. After that, two phases were considered: “in operation” and “at rest”.
A steady-state calculation was carried out for the “in operation” phase , during which a continuous flow of pollution was produced. A time dependent calculation was made for the “at rest” phase, which determined the time required to ventilate a certain amount of pollution. Both phases were considered at the current ventilation rate and two lower rates. For validation, the results of the current situation were compared to the measurements of the actual recovery time. Calculations at lower flow rates have shown us that the required quality level can be guaranteed when the flow rate is reduced to a certain level.
