Design and practice of exhaust systems for underground laboratories in a hospital

Combining the case study of the waste gas treatment system design of the underground laboratories in a hospital in Shenzhen, the design points for the exhaust system construction of the special environment of the underground laboratory in the hospital are analysed. The ideas and practical results are presented related to air change rate, induced draft fan performance, waste gas purification equipment, and purification effect assessment based on the design of underground laboratory partitioning.
