The fan type segment of automotive blower motor market incorporates centrifugal fans, Vane-Axial Fan, Tube-Axial Fan and Propeller Fan
. The centrifugal fan segment of global automotive blower motor market further includes airfoil, forward curved, backward curved and backward inclined fans.
2 depicts the overall system mainly consisting of an evaporator as a dehumidifier, compressor, condenser as the regenerator, an expansion valve (capillary tube), a water tank and propeller fan
. This system is referred as a heat pump type dehumidifier.
The company also provides a complete line of air units for blast freezers or large cold storage facilities, floor-type propeller fan
models, low profile units, work rooms and chill rooms, centrifugal models and high velocity units for quick pull-down in batch-loaded cabinets.
The use of a rotating propeller fan
has been shown to help terrestrial autonomous robots to locate chemical sources by actively drawing air to their chemical sensor and scanning different directions for the presence of chemicals (Nakamoto et al., 1999; Ishida et al., 2001).
* Three ranges of tower efficiencies: "low" was the least efficient available for the cross-flow propeller fan
tower series analyzed with efficiencies ranging from 45 to 60 gpm/hp (3.8 to 5.1 L/sxkW); "medium" with efficiencies ranging from 65 to 75 gpm/hp (5.5 to 6.4 L/sxkW); and "high" with efficiencies ranging from 80 to 100 gpm/hp (6.8 to 8.5 L/sxkW).
