For the purpose of effectively providing protection and utilization of historical earthen sites, the fully-enclosed exhibition halls with electricity driven air-conditioning have been successfully adopted to provide a suitable preservation air environment. However, its electricity consumption and carbon emissions are considerable due to the continuous operation of environmental control, the energy consumption of air cooling in exhibition halls can reach more than 10 times that of office buildings. To further reduce energy consumption, this current study drew on the concept of NBS (Nature Based Solution) and proposed a low-carbon environmental control system for an enclosed exhibition hall for storage of earthen relics by applying natural energy (solar photovoltaic and earth-air-cooling) and space optimization. Firstly, a numerical model was established to simulate the preservation environment in exhibition halls and the electricity consumption of each energy subsystem. Then the model was applied to optimize the design parameters (e.g. earth-air tunnel and airflow pattern) for the environmental control system. Numerical results showed that the electricity consumption was reduced by 58% by applying earth-air-cooling and solar photovoltaic. After optimization of the exhibition hall height, electricity consumption was approximately reduced by 65%. This research is of great value to mitigate energy consumption problems encountered in earthen relics museums and other similar environments.

展厅土质文物存放低碳环境控制系统：基于自然的解决方案视角

为了有效地保护和利用历史土遗址，成功地采用了电力驱动空调的全封闭展厅，提供了适宜的保存空气环境。但由于环境管制的持续运行，其电力消耗和碳排放量相当可观，展厅风冷能耗可达办公楼的10倍以上。为了进一步降低能源消耗，本研究借鉴NBS（基于自然的解决方案）的概念，提出了一种利用自然能源（太阳能光伏和地-空气能）的封闭式土质文物存放展厅的低碳环境控制系统。 -冷却）和空间优化。首先建立数值模型模拟展厅的保存环境和各能源子系统的用电量。然后应用该模型优化环境控制系统的设计参数（例如土-气隧道和气流模式）。数值结果表明，采用地空冷和太阳能光伏发电，电力消耗降低了58%。展厅高度优化后，电力消耗约减少65%。这项研究对于缓解土族文物博物馆和其他类似环境中遇到的能源消耗问题具有重要价值。
