Fans have the specific ratio up to 1.11, blowers from 1.11 to 1.20 and compressors have more than 1.20. Centrifugal designs, on the other hand, impart velocity and pressure to media by flinging them outward with impellers. While most blowers are powered by electric motors (belt and sheave arrangement), some blowers may have with direct-coupled drive motors. HVAC fans and blowers can be mounted to an exterior wall (ventilation unit) or above the ceiling (plenum fan), or used as part of a ducted system (duct fan). (upto 2inch of wg) Pressure rise is mostly due to high absolute velocity of air at outlet of impeller. These fans blow air linearly, and are used for ventilation in small areas that require less space for the fan. Axial industrial fans are used in industries which require large volumes of air at relatively low pressures. Centrifugal Fans and Blowers typically have one of eight types of wheels that draw the air into the inlet of the blower housing, through the wheel, and discharges it at 90 degrees out through the discharge of the housing.. Energy efficiency concepts are introduced, including a component related to the ‘‘affinity laws.’’ Performance Optimization Opportunity Strategies • Optimizing the energy performance of fans and blowers, in most cases, requires that a ‘‘systems approach’’ be taken.
