Description

Technical Field

[0002] Side wall fans are divided into side wall supply fans and side wall exhaust fans according to the flow direction of the conveyed gas. The common forms of air supply in existing factories are: (1) centralized air supply: fresh air is sent into the room after primary filtration, medium filtration, heating or cooling by the combined air supply unit; (2) decentralized air supply: fresh air is supplied through the side wall fan. The first centralized air supply form has a complex system, large equipment investment, and a large footprint. It requires professional personnel to install, debug and maintain it. It is more suitable for large factories and comprehensive commercial buildings. The second decentralized air supply form is relatively simple, with a smaller number of decentralized equipment, simple installation and operation and maintenance, and is more suitable for general small factories, warehouses and single rooms that need ventilation.
