Abstrakt

The target of this contribution is to know if we can use displacement ventilation for the so-called free cooling of a room. What flow rate of air do we need in order to sufficiently reduce the thermal loads in the classroom? We search for the answer to this question by using CFD tools. We only use air from the exterior without any cooling system.

Słowa kluczowe: displacement ventilation, free cooling, CFD
