“…Under these circumstances and according to scientific literature specifications, the HVAC solution implemented for "Vasile Alecsandri" National Theatre of Jassy consists in four HVAC integrated systems serving: Main Hall, stage, foyer and adjacent areas [2]. It is a multi-zone solution which divides the building into 3 areas whose utilization is never simultaneous: Zone 1 -Main hall -stall, lodges and balcony; Zone 2 -stage and orchestra pit; Zone 3foyer and adjacent areas [6]. The HVAC technical data for the building are the following [2]:  Total surface -11.300 m 2 ;  Capacity -740 places;  Total heating power -800 kW;  Boilers -2 units;  Total cooling power -350 kW;  Air chiller -1 unit;  Total supply airflow -33000 m 3 /h;  Total exhaust airflow -38000 m 3 /h;  Air handling unit -6 units;  Exhaust fan -8 units.…”

This study is intended to highlight the role of the ventilation and air conditioning system for a theatre. It was chosen as a case study the "Vasile Alecsandri" National Theatre of Jassy. The paper also sought to make a comparison in three distinct scenarios for HVAC Main Hall system - ventilation and air conditioning system of the Main Hall doesn’t work; only the ventilation system of the Main Hall works and ventilation and air conditioning system of the Main Hall works. For analysing the comfort parameters, the ANSYS-Fluent software was used to build a 2D model of the building and simulation of HVAC system functionality during winter season, in all three scenarios. For the studied scenarios, the external conditions of Jassy and the indoor conditions of the theatre, when the entire spectacle hall is occupied were considered. The main aspects evaluated for each case were the air temperature, air velocity and relative humidity. The results are presented comparatively as plots and spectra of the interest parameters.

COVID-19 is a virus originated from Corona Virus which can severe acute respiratory syndrome (SARS) symptoms such as chest pain, dry cough, fever, and difficulty breathing. The AC and ventilation system is not only important for the thermal comfort occupants but to ensure the room is safe and free from infectious virus. Thermal comfort is important measurement in indoor space which influenced by temperature, Relative Humidity (RH), airflow velocity and others. This research was executed and focused on lecture room in Bilik Persatuan 10, Universiti Malaysia Perlis (UniMAP) instead of real hospital waiting room. It comes with the room dimensions 11.87m (Length) × 5.17m (Width) × 2.93m (Height) for the numerical study. In addition, Computational Fluid Dynamics (CFD) analysis is used to investigate the air flow pattern and temperature distribution inside the room. By using software Ansys FLUENT 19, field experimental and simulation work can be compared which have 14.55% difference in temperature distribution. It is expected by increasing the air velocity of the AC inlet diffuser influence the pattern of airflow in the room, but average temperature remains same for all these conditions.
