Design for exhaust ventilation in Class A workshops in case of accidents

2021-09-14View Original

Thread Content

Design for emergency exhaust ventilation in Class A workshops: the factory building uses a 7-4-7 structure with a span of 4 meters in the middle. The design institute recommended that the emergency exhaust ducts be installed in this central 4-meter span, on the grounds that the glass windows on both sides might be open in case of an accident. We, however, proposed installing them along the walls adjacent to the glass windows on both sides. The reasons for this are as follows: 1) Installing the ducts in the middle would severely interfere with the process piping; 2) Using a single duct for fresh air in the middle reduces the costs associated with insulation work; I don’t know how to design it best!
