Numerical simulation of HVAC system functionality in a sociocultural building

The study presents the functionality of the heating, ventilation and air conditioning (HVAC) system for an important and prestigious objective of Iasi, the "Vasile Alecsandri" National Theatre. A numerical model was created, for the indoor climate analysis, obtaining the main thermal comfort parameters, in different zones of the auditorium. The model carried out on the CFD tool ANS YS -Fluent, is based on the recently implemented HVAC system of the theatre. The results are presented comparatively in two distinct scenarios of the ventilation and conditioning system: when the theatre is occupied and during the breaks. Results from simulation showed that the system provides suitable conditions for occupants and decorative finishing. (C) 2016 The Authors. Published by Elsevier Ltd.
