Application of independent outdoor air variable air volume systems in epidemic conversion of negative pressure isolation wards

The air conditioning system of epidemic conversion wards should meet the different standard requirements of general wards, negative pressure wards and negative pressure isolation wards. Sorts out the design parameters of air conditioning system for each type of wards according to different hospital design standards, including indoor temperature and humidity, air change rate, outdoor air rate, pressure control, air distribution, filtration classification and so on. Summarizes the design parameter requirements of the epidemic conversion wards. On the basis of ordinary VAV systems, proposes an independent outdoor air VAV system, and taking a ward as an example, suggests the control strategies of different ward modes.
