The necessity of HVAC system for the registered architectural cultural heritage building

Abstract

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.

Numerical analysis of the thermal comfort in a church building

“…After that, the influence of the existing and proposed heating system on the indoor climate is shown. [2] [3] Churches preserve many kinds of valuable artworks, each of them with a specific vulnerability, paintings on walls and wooden panels are subjected to cracking, swelling, blistering and soiling. [3] Also the church surprise the eye through the windows made in gothic style, having 0.5 m in width and 1.5 in height with the wall dimension of 1.35 m, made from brick and limestones.…”

[3] Also the church surprise the eye through the windows made in gothic style, having 0.5 m in width and 1.5 in height with the wall dimension of 1.35 m, made from brick and limestones. In plane, the church has the width of 9,80 m, the length of 30 m, the height to the ceiling of 10,60 m and the total height in the towers of 21,70 m. The fact the church is built in triconch plan together with the two orthogonal towers gives a unique image of the church (Fig.…”
