Numerical Simulation of Air Distribution of Lateral Supply and Return Pattern Affected by Indoor Heated Source Distribution Models

Abstract:

In this paper, the numerical simulation was adopted to explore indoor air distribution affected by three typical heated source distribution models, included spatially homogeneous heated source in the room, the heated source distributed evenly at the bottom and the local heated source at the bottom of the room. The characteristics of air distribution effected by three typical heated source models were studied in the air conditioning room with the pattern of lateral supply and return, the scope of rational arrangement in relatively comfortable environment of indoor personnel occupied zone was obtained. The result indicated that, the air distribution with the setting of the spatially homogeneous heated source pattern and the heated source distributed evenly at the bottom pattern were more satisfying than the setting of the local heated source at the bottom pattern.
