Calculation method discussion on differential pressure air volume of air conditioning system of high-level biosafety laboratories

Differential pressure air volume is an important design parameter in air conditioning system design.The envelope air tightness of high-level biosafety laboratories is higher,which has a great impact on the calculation of differential pressure air volume.This paper takes a new high-level biosafety laboratory as the research object,uses the measured value of room differential pressure air volume as a reference,compares and analyses the existing differential pressure air volume calculation methods,discusses the applicability of the existing methods,and explores a more suitable method.
