艺术品对环境因素很敏感，主要是温度和相对湿度，当稳定时，通常被推荐为理想的保护条件，但在历史博物馆建筑中，由于缺乏足够的供暖，通风和空调系统，很难保持所需的条件。本文介绍了分析一年的温度和相对湿度的测量在三个不同的博物馆在波兰。该研究的目的是确定由于不平衡的湿度负荷和不稳定的室内空气温度对博物馆藏品的风险，以及确定这些参数波动的可能原因。本文着重于评估可变的外部和内部负载对室内空气的湿热参数的影响。霍尔斯内部的湿热负荷随时间变化，导致室内环境参数的暂时变化。缺乏适当的系统，塑造分析的博物馆中的微气候，以及现有设备缺乏自动控制，无法将温度和相对湿度保持在适当的范围内。在博物馆，室内温度最高值高于建议的要求。所有博物馆的相对湿度值都超过了建议的范围。
Works of art are sensitive to environmental factors—mainly temperature and relative humidity—which, when stable, are generally recommended as ideal protection conditions, but in historical museum buildings, the required conditions are difficult to maintain, due to a lack of adequate heating, ventilation and air-conditioning systems. The paper presents the analysis of one-year measurements of temperature and relative humidity in three different museums in Poland. The aim of the research was to identify the risk to museum collections, due to unbalanced moisture loads and unstable indoor air temperatures, as well as to identify possible causes of fluctuations in these parameters. This article focuses on assessing the impact of variable external and internal loads on the hygrothermal parameters of indoor air. The profile of internal hygrothermal loads in exhibition halls varied over time, which resulted in a temporary variation of the indoor environmental parameters. The lack of appropriate systems, shaping the microclimate in the analyzed museums, and the lack of automatic control in existing devices did not allow to maintain the temperature and relative humidity within appropriate limits. In the museums, the maximum indoor temperature values were higher than those recommended in the requirements. Relative humidity values in all museums exceeded the recommended range both above and below.
