Museum space separation of visitors from relics preserved in-situ by cool air curtain system

In this research, a cool air curtain system is proposed to separate the relic preservation region from the large space exhibition hall and to keep the local preservation environment steadily and evenly as being desired. Taking the No.15 funerary pit of the Han Yang Ling museum as an example, a stream function method is adopted to design the prototype of the cool air curtain system, and a computational fluid dynamics model is proposed to predict the performance of the cool air curtain system. Numerical results show that the system can isolate the relic domain from the display area effectively. The theoretic isolated efficiency is up to 92.0%. Moreover, through this system, the temperature distributions in the local relic preservation domain are kept steadily and uniform. This system provides a new idea for environmental control of the preservation in-situ of unearthed relics.
