NATURAL VENTILATION AIRFLOW MODELLING : CFD ANALYSIS : DETAILED HVAC SYSTEMS INTEGRATION : DAYLIGHT STUDIES

Do you need to analyse particularly localised conditions accurately? Dynamic simulation modelling (DSM) operates on a zone principle, each room typically being represented by a zone. The results tell us the average conditions across that zone which is no use when we need to ensure no part of a room goes above a threshold temperature and that’s where CFD comes in.

Computational fluid dynamics (CFD) provides a holistic understanding of heat flows, flow rates and the temperature distribution within a zone at any instant. It does this by splitting each room into hundreds of thousands of cells that interact with each other.

This gives a definitive set of expected conditions and allows us to test a whole range of options so that we can design the most effective HVAC solution.

CFD is also applied externally to predict the impact of the wind environment over the whole of a development and its surroundings. Buildings, especially tall structures, play a major role in determining airflow patterns and velocities at pedestrian level, thus evaluating and understanding their impact is an essential piece of the jigsaw. 

If you have a critical process or specific local parameters that cannot be exceeded, CFD will provide certainty that your environmental treatment systems will perform the way they have been designed.
