Description:

It is recommended that participants take this course prior to attending the ACCA Manual D, Advanced Manual D.  This computer-based class will cover whole house and room-by-room ACCA manual J Version 8 Load Calculation methods.  The instructor will also review the ACCA Manual S Equipment Selection Manual.

Special Note:  Computers will be provided, but students should have basic computer skills such as being able to save and rename files, and use a mouse to click and drag.

It is recommended that participants attend this class prior to attending the Advanced ACCA Manual D class. This class provides a review of the ACCA Residential Design System and approved software, Manual D procedure, and proper documentation. Learn how to achieve efficiency compliance while optimizing ductwork for competitive pricing and comfort. North American Technician Excellence (NATE) continuing education credits are available for this class.

Many homeowners are considering changing ‘Gas Furnaces’ to ‘Heat Pumps’ to provide  residential heating and cooling.
The Training builds upon the ACCA Wrightsoft series and focuses on the Science of correct sizing of Heat pump systems and includes a Wrightoft computer lab portion.

The session builds upon Manual ‘J’ and provides a foundation upon which Manual ‘H’  will be built.
It is recommended that attendees bring their own laptop preloaded with the Wrightsoft Demo software

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 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:

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.

As homes become tighter and use energy more efficiently, airflow and airflow balance is going to become increasingly important . Comfort and indoor environmental quality are dependent upon proper airflow into each room. The session starts with a classroom discussion covering the basic science and calculations involving airflow balance. Followed by a lab session that allows the material covered in the classroom to be put to practical use in a lab exercise.
Airflow measurements will be made with a flow grid and flow hood, other topics that will be demonstrated focus on the California Title 24 Part 6, approved Airflow measurement and Fan Watt efficacy calculations.
