Describes factors to be taken into account for air conditioning and heating in a theatre. Nature and purpose of the building call for an adequate supply of conditioned outdoor air, with a total supply air rate up to 69,000 m3/h. Economical use of energy was stressed. Detailed description of the problems involved with the auditorium and stage shaft are given.
The introduction describes the principle of SVP (Solar Ventilation Pre-heating) and then reviews a number of current related topics. Heat recovery is considered. Work on other devices which produce solar heated air is reviewed. The main driving forces of natural ventilation are wind pressure and thermal buoyancy. One of the problems is that the magnitude of these forces is very variable. The basis of SVP demands a thorough knowledge of airflow through buildings.
