Analysis and discussion on common issues of smoke control system in fire acceptance process

Investigates the common issues of smoke control and management system in engineering practice and suggests the solutions from design, construction and installation. Points out that beams, columns, multi-blade air supply outlets and multi-blade smoke exhaust ports should be avoided protruding into the mechanical pressurized air supply duct and smoke exhaust duct. The inner wall of duct should be smooth and tight and without air leakage. The air outlets of the duct should be blocked by fireproof material. Air leakage volumes of the air duct and smoke exhaust valves (air outlets) should be calculated to meet the smoke exhaust requirements in large smoke exhaust system. The functions and the control requirements of air valves (air outlets) should be illustrated clearly in the design specification.
