Manual S® - Residential Equipment Selection (2nd Edition) [ANSI/ACCA 3 Manual S - 2014]
New for this edition:
Contains new sizing rules that recognize multi- and variable speed equipment with larger over sizing limits.
Covers 11 types of equipment (previous version covered only four).
Heat pumps in heating dominated locations have an optional over-sizing procedure.
There are an increased number of example problems for Manual S procedures, as well as explanations of details/nuances (for contractors and educators).
The book is reformatted so the first sections contain mandatory code official language.
