Simulations And Analyses On Air-condition Design For Theatre

Analysis is presented with the design of the theater's air-conditioning examples, research on key technologies of Dynamic load calculation,Ventilation air-condition model of large space building,The interior and outdoor noises control,Air-cooled heat pump unit design and pattern selection.Load calculation plays an important role in the practice of Air-condition design, This text sets out from the model of Annual weather parameter, the Annual Dynamic load calculation based on the special building was dynamically simulated with the software—DeST, scientifically ascertain the energy consumption of the building, reached design optimization,decreasing energy consumption,economizing resources,reducing initial investment. According to the features of large space building like as theatre, different Air-conditioning ways on different area should be used: the Air-supply method of the stage is lateral supply and return, the Air-supply method of the auditorium is upper supply and bottom return by swirl diffusers. Simulates the temperature and velocity field of the stage in different air-supply heights with Fluent software, the rational air flow distribution has been obtained. Theatre buildings demand noises very rigidly, in order to reduce the influence on the internal and external environment from unit operation, the design is characterized by its noises control. Noise control for units by sound insulation screen, installing mufflers on air supply duct of unit and swirl diffusers, it received good effect on reducing aerodynamic noise. There are universal applications of the Air-cooled heat pump at cooling & heating sources of air conditioning, the advantages are also discussed.
