Industry moving toward more efficient cooling. [Variable air volume (VAV) systems]
The popularity of energy-efficient variable air volume (VAV) systems has spread from new commercial buildings to industrial construction. The high initial costs of VAV have only a four- to five-year payback because less horsepower is needed to move air through the air conditioning system and chillers are able to run at their highest level of efficiency. The greater the building's variation between peak and minimum loads, the greater the energy savings. Areas with periodic needs, such as school cafeterias, are especially well suited to VAV systems. The system does not presently lend itself to either the heating mode or to retrofitting. The improved working conditions made possible with VAV attract and hold skilled labor. Using conventional refrigeration, cooling tower, and pumping equipment, VAV differs in the use of vane axial fans for more efficient air movement. Suppliers of industrial cooling systems and air conditioning equipment are listed.
