Abstract

Historical earthen sites are bright stars in historical and cultural heritages. In order to effectively protect and display earthen sites (including cultural relics and soil), the fully-enclosed exhibition halls are established but without any environment control system. This will lead to some diseases of earthen sites, e.g., crystallization, structural cracking, which is due to continuous water/moisture loss of earthen sites. Hence, this work aims to control water and heat transfer between earthen site and ambient environment by proposing an energy-efficient environment control system, based on optimal design of ventilation and air conditioning. Numerical strategy was developed to calculate heat & moisture transfer between air and relics. Further this model was applied to optimize key design parameters (e.g. inlet air parameters) of environment control system through numerical simulations. Compared to fully-enclosed exhibition hall without control measures (moisture loss, −1.65 g/s), the moisture loss issue is solved by environment control system with optimal design (moisture gain, 0.013 g/s). The parameter design of control system is very essential, and different design parameters can lead to deviation of energy consumption up to 71%. This research is of great significance to mitigate the deterioration problems of enclosed exhibition hall of earthen relics, and the proposed numerical strategy can provide a useful tool for the control of other similar physical environments.
