ARLINGTON, Va. - The Air Conditioning Contractors of America (ACCA) has announced the publication ofBob's House, a step-by-step case study in the proper design of a residential HVACR system. Written in plain English, the book follows the ACCA residential design system, an industry standard method used nationwide by contractors and recognized by national building codes.
The full ACCA residential
design system incorporates Manual J (load calculation), Manual S (equipment
selection), and Manual D (duct design).Bob's Houseexplains how the system comes
together in the real world.
Bob's Houseis intended to be a resource for building
code officials, homeowners, technicians, and anyone else who wants a better
understanding of the HVACR design process. It proceeds from the delivery of
building plans to a contractor, until he or she produces documents that could
be used for permit applications, homeowner proposals, or a plan for HVAC
technicians to follow as they install the new system.
This general guide does
not teach the reader the laws of thermodynamics, or how to calculate a home's
heating and cooling requirements, and does not examine all equipment or duct
system types or provide load calculation tabular data. However, it does
explain how the information from these calculations is used to properly design
a home's heating and cooling system.
The guide also includes
several appendices that explore what would happen if Bob's house were located
in a different city, or if his builder had used different building materials,
and other possible variations. Other appendices discuss different equipment
types and duct challenges, and provide an illustrative example of how
information might be presented for a permit application.
