Analysis on thermal comfort in summer and winter in Chinese department stores.

Author(s) : ZHAO J., ZHANG W., WANG J.

Summary

Considering the characteristic of the air-conditioning system in large department stores, a computational model on three-dimensional air supply unit is established, based on the formulas on turbulent flow. With the model, the air velocity field and the air temperature field, separately in winter and in summer, of the air-conditioning systems with top-supply and top-return are simulated and the simulated results are calculated by mean of the CFD software. Then based on the Fanger thermal comfort equation, the indoor thermal environment of Chinese department stores is predicted through two thermal indexes, predicted mean vote and predicted percentage of dissatisfied, using the calculated data of the air supply unit. The effect on indoor occupant at different supply air conditions is analyzed. The optimum indoor design data are suggested.
