Comparative analysis of technical requirements for Heating, Ventilating, and Air Conditioning (HVAC) systems in high-biocontainment facility standards

Abstract

In this study, standards of high-biocontainment facilities (including laboratories and large-scale production facilities) formulated by China and other countries were analyzed and compared, and the technical points and requirements for Heating, Ventilating, and Air Conditioning (HVAC) systems in different series of standards were discussed. The main focus was on expounding the design and verification of the containment area’s indoor parameters, ventilation system, filter design, integrity test, fan standby, airflow pattern, and system reliability. This study expects suggestions and opinions on the construction and development of biosafety facilities in China and the possible future revision of relevant national standards.
