Abstract:
In order to evaluate the air distribution using CFD method scientifically, former evaluation indexes of air distribution are modified by quality weighting method. A numerical simulation model is developed for the calculation and verified by experiment. Indoor air distribution in four operating modes of ceiling mounted indoor unit is simulated with the model. Comparing the existing evaluation indexes and the modified ones, it is found that significant differences in the indexes result in different evaluation results and the modified ones are more reasonable and appropriate.
