A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."
Inlet and outlet ducting are often attached to the fan's housing, to supply and/or exhaust the air or gas to the industry's requirements. There are many varieties of centrifugal fans, which may have fan wheels that range from less than 3 cm to over 16 feet (4.9 m) in diameter.
Carey Smith incorporated the Delta T. Corporation in 1994 Lexington, Kentucky, to manufacture and install cooling systems for industrial spaces and warehouses. [1] In 1999, Smith signed an exclusive distribution agreement with a California manufacturer of "high-volume, low-speed" (HVLS) ceiling fans, which were sold to farmers for cooling cattle. [2]
HVAC ventilation exhaust for a 12-story building An axial belt-drive exhaust fan serving an underground car park. This exhaust fan's operation is interlocked with the concentration of contaminants emitted by internal combustion engines. Mechanical, or forced, ventilation is provided by an air handler (AHU) and used to control indoor air quality.
Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
For purposes of air conditioning, the Han dynasty craftsman and engineer Ding Huan (fl. 180 CE) invented a manually operated rotary fan with seven wheels that measured 3 m (10 ft) in diameter; in the 8th century, during the Tang dynasty (618–907), the Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the ...
