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
Class Overview: A residential split system air conditioner undergoes its final assembly at the time of installation. An important factor is the amount of refrigerant in the system (commonly referred to as proper charging). Air conditioner energy efficiency suffers if the refrigerant charge is either too low or too high. This training is designed to assist HERS Raters and HVAC technicians to properly perform a Refrigerant Charge verification. This is a Hands-on class with operational equipment. Please feel free to bring your verification equipment.
Class Overview:
This 1/2 day class covers Manual ‘J’ Sizing Introduction Manual ‘J’ Wrightsoft Set-up and hands on training Detailed Cooling Capacity Data Sheets Air Flow Calculation Worksheets
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.
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.
The New Homes Solar Partnership for Solar PV rater verification process is covered in full day class and includes information on the program plus efficiency measures (building envelope and renewables including PV and Solar Thermal), photovoltaic system siting, shading, equipment verification, PV system technologies, Title 24 Residential Performance compliance, tangent lookups, compass rose, installation and verification information and solar glossary.
Electricians and other building professionals interested in Solar PV installation.
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.

This ½ day program goes through the Building Science behind Heat, Moisture and Pressure transfers that occur dynamically each day. Using the principles found in the “Second Law” we can locate problems affecting buildings. This is part of the Series dealing with Building and Pressure Diagnostics.
