Class Schedule
Class Overview:
This 1/2 day class covers Manual S, Sizing of Residential Equipment based on Manual S and the California title 24 Part 6 parameters. Material includes: Reference App JA-II, Various Manufacture Equipment Data sheets, a PowerPoint with a step-by-step work through, and a Wrightsoft Computer element, Other ACCA Approved Software is being brought into the training at this time.
The course covers Basic concepts of duct design. Covers air flow dynamics and static pressures within the systems, defines and explains EL, friction rate, location, throw and spread of grilles, registers and diffusers. Includes a Software portion for Wrightsoft and will include Elite. The information covers efficiencies relating to design, installation as well concepts focusing on delivered efficiencies, operating points, fan and duct curves.
Class Overview:
Day 1 – Building Energy Science I
CLASSROOM: Review basic Energy Science and Pressure Diagnostics, Manometer Law and Manometer Usage
HANDS ON: Blower Door, includes four set-up stations and both TEC and Retrotec equipment using multiple manometers. Includes both Pressurization and Depressurization Techniques. Duct Testing Total Leakage and Leakage to Outside Multiple opportunities to set up check the equipment operation procedures.
Class Overview:
Day 2 – Building Energy Science
CLASSROOM: Discuss ‘Static Pressure and Airflow, Air Flow Measurement Techniques-Plenum Pressure Matching Method, Flow Hood, Flow Grid.’
HANDS ON: Measurements-Static Pressure and Airflow, Using The equipment approved in California. Fan watt draw and Airflow using Retrotec and TEC equipment.
Class Overview:
Properly maintained and calibrated equipment insures measurement accuracy in the field and improves equipment performance and longevity. 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.
Class Overview:
Day 3 – Building Energy Science
CLASSROOM: Discuss ‘Refrigerant Charge’ and ‘Equipment Calibration’.
HANDS ON: Combine the Airflow techniques with Refrigerant charge procedures, Multiple opportunities to practice on various pieces of equipment.
Class Overview:
Day 4 – Building Envelope
CLASSROOM: Discuss ‘Combustion Analysis’, ‘Room to Room Pressure Diagnostics’ and ‘Duct Leakage Diagnostics’.
HANDS ON: 80 and 95 AFUE Combustion analysis, and Room to Room pressure diagnostics including Duct Leakage Diagnostics, (finding leaks with a manometer).
Class Overview:
Day 5- Building Envelope
CLASSROOM: Discuss ‘Thermal Bypass and Quality Insulation Installation’, ‘Thermal Imaging’.
HANDS ON: Inspect a wall section, working some of the areas discussed, Use an IR camera and review the results, using a hot wall for the training.
