HVAC technicians work on fans in many ways. They install fans, measure fan performance, and adjust fan speed. This article provides important advice on how to work safely with fans.
On air-handling units, air intake filtration increases the life of internal filters. On air-cooled chillers and condenser coils, it prevents debris from getting into the coils. On cooling towers, it isolates debris on the outside of the tower.
Typically, green buildings save close to 30 percent of the energy and 50 percent of the water that buildings of comparable size waste. Those occupying these buildings claim improved health and lower utility bills.
This article reviews ASHRAE Standard 90.1's requirements for airside economizers and discusses the underlying design decisions and benefits of effective airside economizer systems.
