ABSTRACT Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment.

新型展示柜设计的实验和数值分析：翻新安妮·弗兰克之家的案例研究

摘要 许多博物馆都坐落在历史建筑中，有时建筑本身也是博物馆藏品的一部分。通过提供接近恒定的温度和正确水平的相对湿度来创造稳定的环境，可以降低物体退化的风险。然而，保持这种稳定的室内环境会增加能源消耗和历史建筑的风险。博物馆展示柜通过为室内气候波动提供额外的保护层，为减轻贵重物品可能遭受的风险提供了解决方案。安妮之家是位于阿姆斯特丹的一座历史悠久的房屋博物馆。博物馆在过去几年中经历了几次翻修，以应对每年超过 120 万游客的增长。安妮·弗兰克的原始日记和其他文件永久陈列在安妮·弗兰克之家。随着最近的翻新，设计一个新的最先进的展示柜的可能性出现了。本研究介绍了与原位设计相关的实验研究结果。对新展览空间和新展示柜内部的温度和相对湿度进行监测，以深入了解这些受控环境的湿热行为。进行了补充性数值研究，以研究在各种情况下展览馆的动态气候控制和陈列柜中的气候条件的影响。本文提出了四个主要结论。所研究的展示柜设计能够通过硅胶提供稳定的相对湿度环境，同时使用有源箱中箱气候控制系统来创造稳定的温度条件。机箱内温度取决于展示柜空气处理装置提供的温度。如果展示柜的气候控制系统出现故障或故障，则必须制定协议。在采取必要的行动之前，需要关闭机箱的空气处理单元，为展示的物体创造一个被动的环境。当陈列柜中陈列着易受影响的博物馆物品时，展览馆的设置点可以不那么严格。环境是分开的，并为节能设定点策略提供了机会。
