The Air Conditioning Contractors of America (ACCA) at its national convention in Kissimmee, Fla., introduced the latest version of the popular Manual J, the updated Version 8.
It was a collaborative effort by ACCA technical consultant Hank Rutkowski, and Glenn Friedman, a technical consultant for Taylor Engineering, Almeda, Calif.
Highlights of the new manual include ways to better calculate peak loads, as well as improved heat loss calculations for windows, multiple-zone calculations, duct load factor tables and cfm requirements including updated IAQ information. The manual is available on CD.
