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. The fan since the wind chassis, muffler favor. 3. When the fan selection should consider piping system leakage losses calculation error principle of centrifugal wind chassis, as well as the actual air volume fan, negative pressure deviation, the general air volume of 1.05 to 1.1 centrifugal wind chassis models, pressure 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. To make the fan stable operation HTFC-A centrifugal wind chassis, should make the fan work near 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 Located total pressure peak 80%). Note the fan installed; base a, fan required level, rugged, and base height ≥200mm. b, the use of fan and duct hose (flexible material without burning) connection, the length of not less than 200mm, import and export of the same diameter and fan size. To ensure the hose in the system during operation does not appear distorted centrifugal wind chassis, install the appropriate degree. For the fan mounted on the suction side of the canvas hose, install a little more tight, to prevent the fan operation is drawn to reduce the size of the canvas hose section. c, the fan must be fixed in concrete steel frame, based on the need to increase damping rubber pad between its steel frame and fan base. All the fan and motor assembly is mounted on a piece of steel frame, damping steel frame mounted to the top of the base pad damping pad is best to use porous rubber plate. d, the diameter of the fan outlet only larger, not smaller, the last outlet to install insect nets, tend to be increased on the wind when the wind and rain hat.
