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

With a focus on ACCA’s Manual N5AE this training helps contractors develop an understanding of how to calculate the various components of a commercial facility’s heating and cooling load using computer based software.

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.
