It is recommended that participants attend the ACCA Manual J Equipment Sizing and Selection and ACCA Manual D Duct Design courses prior to attending this class. This class will step beyond the introduction to ACCA Manual D to more advanced topics, including how to perform Manual D calculations both manually and using the official Wrightsoft ACCA computer software program.
This class will be presented using computers for hands-on training. Participants will perform group exercises and have the opportunity to work on individual problems with the instructor’s assistance.
Class topics will cover:
– Homes with multiple HVAC systems.
– Two-story homes with single systems.
– Using the computer program to generate room-by-room load calculations and select HVAC equipment.
– How to use the graphic design module of the computer software, which automatically calculates room-by-room load calculations and provides Manual D duct design.
