Manual J – Reviews the fundamental concepts of ACCA’s Manual J and shows where to put that information into the  program. Using a supplied floor plan attendees perform a complete heat load, learning to:

  • Calculate the conduction load through selecting construction material from the built in tables.
  • Using the software to calculate solar gains.
  • Input data for duct, infiltration and internal loads.
  • Quick tips to enter data with a single mouse click.

Manual D – Attendees calculate a Manual D using RHVAC’s Tabular function. Methods to choose fittings and determine friction rate are also discussed.

Manual S – Learn how to select the equipment using manufacturer’s extended data sheet to perform a Manual S interpolation. The class start with a discussion on why a Manual S is important. Sample extended datasheets are provided.
