Design and operation of air conditioning and ventilation systems in shelter type emergency isolation places

Combined with the practice of the shelter type emergency isolation reconstruction project, aiming at the design and operation of the air conditioning and ventilation system, this paper analyses the key problems to be considered in each link and countermeasures. From the perspective of system design, the key points and countermeasures of pre-evaluation, pressure gradient, air distribution, filtration and sterilization, utilization of the original system or equipment and standby are summarized. From the perspective of system operation, the key points and implementation suggestions such as equipment startup and shutdown process, and filter maintenance are summarized. Finally, from the perspective of filters, duct systems and rapid transformation space design, this paper discusses the combination design of air conditioning and ventilation system in the post epidemic era.
