Numerical simulations supporting project design

With the help of numerical simulations (CFD =Computational Fluid Dynamics) we are able to develop new products in a very short time and predict the suitability of project solutions with high accuracy.

At OC IMP Klima we regulary use CFD to examine key factors, which influence the indoor climate, such as velocities (vectors), temperature, pressure, concentrations and turbulences, but also heat transfer and phase transformation (condensation).

Especially in case of larger projects and customized solutions we can thus efficiently support investors or designers in the phase of project design and evaluate possible alternatives in theory, before carrying out practical tests in the laboratories of the OC IMP Klima R&D center. Some examples are shown below.

Heating of an aircraft hangar

Study of the predicted velocity and temperature inside a closed hangar during winter operation. The main question was, how much time is needed for heating up surfaces inside the hangar and the aircraft itself so that the maintenance on the aircraft could be started. As the optimum solution, we proposed supplying heated air via variable air nozzles, installed on both sides of the hangar.

Optimum air velocities for gymnasts

In a sports hall for rhythmic gymnastics low air velocities in the central ground floor area must be ensured for the gymnasts to perform. At the same time, in the spectator's area high thermal loads are present. A combination of air nozzles, proper positioning of the air exhaust and cooling of the lighting elements and other equipment enables very low velocities in the central area up to 10 meters height and pleasant temperatures on the tribunes.

Fire and smoke extraction in underground garages

In the area of fire and smoke extraction, CFD was used to set a proper position and performance on jet fans and thus guarantee enough evacuation time for all occupants inside one floor level of the underground garage. Jet fans are positioned in a way that ensures proper pressure fields inside the garage to efficiently extract smoke.

Airflow patterns in an industrial kitchen

The CFD study of a large commercial kitchen revealed airflow patterns and surface temperature positions. The ventilation rates and low local temperatures ensure excellent thermal conditions and pleasant indoor climate for the kitchen staff.
