Sheet Metal and Air Conditioning Contractors’ National Association Releases Two New Standards

The Sheet Metal and Air Conditioning Contractors’ National Association released two new standards. First is the second edition of the Kitchen Ventilation Systems and Food Service Equipment standard.  This standard continues to serve as a reference guide to industry-accepted practices for the fabrication and installation of commercial kitchen ventilation systems, as well as custom-built food preparation and serving equipment.

Also released was the HVAC Duct Design Guide (fifth edition) in Spanish. The manual presents the methods and procedures for designers to properly design an HVAC air distribution system, as well as detailed information on duct design, duct fitting selection, examples, calculations and tables.

In addition to the basic engineering principles for the sizing of HVAC ductwork systems, the manual also provides detailed information on: air distribution materials, methods of construction, economics of duct systems, duct system layout, pressure losses, fan selection, duct leakage, acoustic considerations, and testing, adjusting and balancing.
