Commercial System Design Training

See any upcoming classes here.

If your company needs simplified, practical procedures for calculating both heat loss and heat gain in small to medium commercial structures using unitary air conditioning equipment, this Manual N training is for you.

With a focus on both manual and computer methods, this advanced training helps contractors develop an understanding of how to calculate the various components of a commercial facility’s heating and cooling load.

While emphasis is placed on identifying and calculating peak load conditions, discussion is also directed at understanding the structure’s needs under part-load conditions. Much of the information covered is based on the ASHRAE Handbook of Fundamentals. Days 1 and 2 are spent learning Manual N commercial load calculation fundamentals. Day three is devoted to learning Wrightsoft’s Right-N computerized commercial load calculation program.

Areas covered include:
• Outside Design Conditions
• Inside Design Conditions
• Solar Radiation Heat Gain Through Glass
• Heat Transmission Through Structural Components
• Heat Gain From Internal Sources
• Ventilation Loads
• Infiltration Loads
• Dehumidification Loads
• Identifying time-of-day peak cooling
• Duct Heat Gain & Loss
• Completing the Manual N Form

In the final exam, students prepare a manual load calculation on a light commercial facility. While not a requirement, it is suggested that students complete Manual J, residential load calculation training or the equivalent before attending this class.

SPACE IS LIMITED IN EACH CLASS. Note, food and lodging are the responsibility of the student.
