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.

This full day training class is designed to introduce HVAC Contractors, General Building Contractors, and Mechanical Engineers to the process of duct design and register selection when installing small Commercial HVAC systems.
This class includes four specific components:
1. Classroom instruction of the ACCA Duct Design procedure.
2. Classroom instruction on effects of CFM, velocity and pressure on duct desgins and general airflow terminology.
3. Duct sizing practice exercises.
4. Register selection and placement.

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.
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 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.
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.
