Résumé

The design cooling load of stratified air conditioning system in large-space buildings is usually calculated by the empirical coefficient method, and there is little research on the airport terminal buildings. Takes the departure hall for remote parking bay, departure hall for near parking bay and chick-in hall of a terminal in Wuxi as examples. By modifying the air jet parameters in summer air conditioning design condition with the CFD software, the average temperature in occupied zone would reach the indoor designed requirements. The cooling load of stratified air conditioning system is decided by the air jet parameters, and the reduction ratio of cooling load of the stratified air conditioning system to that of the well-mixed air conditioning system is obtained. The difference between 1 and the reduction ratio is the empirical coefficient value for cooling load of airport terminal buildings. The results show that the empirical coefficient for airport terminal buildings should be from 0.85 to 0.95, due to the small proportion of cooling load from the envelope and few exhaust openings in the upper zone.
