ADPI characteristics of line diffuser in a room with perimetric heating load

The distributions of air velocity, temperature and humidity are affected by the types and shapes of diffusers for supply air in an occupied zone. So it is important to select proper diffusers in the design procedure of the HVAC systems. The aim of that study is to propose a selection guide for a proper line diffuser in a room when perimetric heating load exists.
In this study, the ADPI (air diffusion performance index) characteristics of high sidewall line diffuser have been examined by a numerical method with various heat load ratios when the opposite wall from the diffuser is heated.
