Air conditioning and ventilation design for ward buildings in an infectious disease hospital combined with peacetime and epidemic period

The design of double-condition air conditioning and ventilation system for infectious disease ward buildings is presented from the aspects of system design, air handling, pressure gradient and air distribution. Based on the calculation and analysis of the ventilation rate in the key functional areas of the ward building in peacetime and epidemic periods, the technical measures for the peacetime and epidemic period transformation of the air conditioning and ventilation system are summarized and refined.
