hvls fans residential A high-volume low-speed (HVLS) fans is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. are generally ceiling fans although some are pole mounted. move slowly and distribute large amounts of air at low rotational speed– hence the name “high volume, low speed. “Typical applications for fall into two classifications—industrial and commercial. In industrial applications, HVACR is often cost prohibitive or impractical, and is usually only used for refrigerated warehouses or the manufacture of refrigerated or frozen foods. Fans installed in spaces like warehouses, barns, hangars and distribution centers can prevent heat stress, increase worker comfort and the productivity of both workers and livestock. are also used in commercial spaces, where air conditioning is more common, but increased air movement from ceiling fans can cost-effectively augment occupant comfort or prevent stratification. Typical commercial applications include shopping malls, churches, office buildings, airport terminal buildings

How HVLS fans work

HVLS fans  residential work on the principle that cool moving air breaks up the moisture-saturated boundary layer surrounding the body and accelerates evaporation to produce a cooling effect. Ceiling fans produce a column of air as they turn. This column of air moves down and out along the floor. Called a horizontal floor jet, this deep wall of horizontal moving air is relative to the diameter of a fan, and to a lesser degree, the speed of a fan. Once the floor jet reaches its potential, it migrates outward until it meets a side wall or other vertical surface.

Measuring fan performanceEdit

In general, Air Movement and Control Association Standard 230 sets uniform testing procedures for determining ceiling fan performance.

AMCA 230 establishes uniform methods of laboratory testing for air circulating fans in order to determine performance in terms of thrust for rating, certification or guarantee purposes. The 1999 version described a method to determine the thrust developed and used a simple equation to convert the measured thrust to airflow. During the periodic review process, it was determined that the calculated airflow was too high; therefore this version no longer artificially calculates airflow, but leaves the measured performance in units of thrust.

The current version, AMCA 230–12, reintroduced airflow rate with a revised equation, and new efficiency metrics. The official scope of the standard was limited to ceiling fans under 6 feet (1.8 m) in diameter. Therefore, the current standard does not apply to HVLS fans. A new version of the standard is currently under review.
