A CFD Simulation of Cold Air Distribution System with Different Supply Patterns
Cold air distribution systems can potentially lower operating and first costs when compared to conventional air conditioning system. One concern for cold air distribution is that the cold supply air temperatures can be uncomfortable. Air distribution and comfort in a typical room with cold air diffusion was investigated by the method of CFD. A mathematics model was established and the air distribution was stimulated. The velocity and temperature fields of the airstreams in the room at different conditions were analyzed. The result shows that the air fallout is easily generated and the air detention area and eddy current are existent. The same case occurs with both ceiling and wall air supply.
