Type fan aerodynamic performance test: GB1236 "fan aerodynamic performance test methods" in the company's air duct, air-chamber test device DBF wind chassis, with advanced testing, testing equipment for the factory fan comprehensive performance by bulk sampling test. All design and development of new products and product standards derived products must tested aerodynamic performance laboratory and test reports issued two-speed exhaust air box, performance indicators meet the design requirements were only put into full production. He choose wind chassis? Fast net to consider advice from the following: Noise: Because wind chassis is mounted on the ceiling inside the device, and when you go to bed at night is going to open HTFC-A exhaust air box, if the noise is too large, it will affect the rest of the evening. Power: If the power is too high, the high cost makes the machine run. Size: larger size will affect interior ceiling space, so a smaller size can win more space.
