Study on the difference of air flow organization in exhibition halls of archives in Beijing

In recent years, with the increasing frequency of archive exhibitions held by comprehensive archives at all levels, the people-centered archival service philosophy has taken root in people's hearts. Conducting empirical research on airflow organization in archive exhibition halls can provide research methods and foundational data support for the design of airflow organization in exhibition halls during the construction of archives. This paper compares and analyzes the actual measurement data of airflow organization in the exhibition hall of an archive in Beijing during winter, revealing that the overall visitor route and design of the exhibition hall are relatively complex. The internal structure and space design struggle to achieve uniform symmetry, and asymmetrical structures lead to deviations in internal temperature uniformity. Moreover, when the secondary detailed design of the exhibition hall is carried out, there is no corresponding adjustment in equipment configuration for airflow organization and humidity control, resulting in uneven distribution of temperature and relative humidity. To address these issues, it is proposed to strengthen the setting of temperature and humidity control values for different control systems, adopt dual-system control with separate regulation to maintain consistent greenhouse and humidity ranges across different systems, better meet the needs of different spaces, improve the uniformity of temperature and humidity, and reduce the differences in airflow organization among various areas within the exhibition hall.
