Class Schedule
This session covers the science and application of airflow principles to the efficient operation of HVAC equipment. Many of the residential systems in California suffer from the inefficiencies caused by high static pressure. Included in this training is a hands-on portion designed to compare various filters, fittings and layout issues that cause high static pressures.
Description:
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 instructors 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. North American Technician Excellence (NATE) continuing education credits are available for this course.
Class Overview: This class will feature free equipment calibration. Attendees will have the opportunity to check HVAC, 
blower door and duct tester equipment calibrations. Instructor Gary Wollin will show attendees how to apply the principles for calibrating digital thermometers, refrigerant gauges (P/T) and pipe clamps used for checking pipe temperatures for both the liquid and suction lines. Attendees will be shown the field test procedure for digital manometers and be able to check personal manometers against newly calibrated manometers. Duct blaster inspections for proper airflow will also take place. There will be a demonstration on how to maintain duct blaster equipment including cleaning and checking for damage, and misalignment of the fan and plugged orifices.
