Thermal comfort optimization of a large atrium based on individual demands

Taking an atrium building in Shanghai as a case, analyses the indoor thermal comfort issues of the large atrium in winter conditions, puts forward the optimal suggestions and measures and implements the reformation using electric film heating systems in working zones to improve the indoor thermal comfort. Testing and numerical simulation results of reformation effects show that the working zone temperature increases from about 14 ℃ to higher than 18 ℃, satisfying the demand of thermal comfort.
