[0002] Ventilation ducts can be divided into two types: air supply ducts and exhaust ducts. Air supply ducts are mainly used to introduce fresh air. Common air supply ducts include air supply ducts of fresh air systems and air conditioning systems. Exhaust ducts are mainly used to exhaust dirty air in the room. Common exhaust ducts include exhaust ducts of exhaust fans and smoke exhaust ducts of kitchen exhaust systems. Ventilation ducts are duct systems used for indoor air circulation and ventilation.
