摘要：In this paper, a superimposed ventilation system is introduced to satisfy personalized demand in air-conditioned room. The system is combined by a general mixed ventilation part and some local ventilation parts. The general ventilation provides background air flow pattern; the local ventilation is used to adjust personal parameter. By a case study, the indoor air parameters of some scenarios are calculated by numerical simulation method, and the characteristic of superimposed ventilation is analyzed. The results show that, the superimposed ventilation is more effective than general mixed ventilation on guaranteeing local demand. Finally some related issues of superimposed ventilation are discussed preliminarily. The superimposed ventilation system provides an easier way to satisfy Individual demand in air-conditioned room. The system could be applied in building construction flexibly and applicably.
