1. The choice of the control parameters for wind chassis air flow, total pressure, efficiency, noise, and electrical power. There are centrifugal and axial flow. 2. Fan the provision of the two-speed centrifugal wind chassis wind chassis, muffler favor. 3. Fan Selection DBF air when the wind chassis, you should consider piping system leakage losses, calculation errors, as well as the actual fan wind, air pressure negative deviation wind chassis, the general air volume of 1.05 to 1.1, pressure for safety factor of 1.10 to 1.15. But not using too large, long-term in order to prevent the fan zone inefficient operation. 4. Note the pipe resistance characteristics matching networks and fan characteristics. For the stable operation of the fan, the fan should be made to work in the vicinity of its maximum efficiency point, the operating point of the fan performance curve to the right of the peak point of the total pressure (ie, the amount of side winds, and generally all-pressure peak of 80% ). 1. Fan mounting pedestal (base) should have sufficient strength, stability and durability saving centrifugal wind chassis vibration pedestal shall meet the following requirements: 1) basic vibration frequency device shall not exceed the motor and fan speed 1 / 3.2) the difference between a vibration velocity and vibration speed fan operation is a stationary fan when more than 3 times greater than required. The connection between the import and export with duct 2. The fan should be set flexible joints. Inlet duct, the duct, and other devices should be supported independently by the foundation or support other components of the building firm, should not bear the weight of other chassis parts are. 3. When the fan is mounted on the building elements, isolation measures should be taken.
