HVAC design & drafting
In this course, we aim at teaching participants how to make out a complete HVAC design & drafting for a HVAC project. We will introduce the different modes of heat transfer, the methods used in determining the cooling load for a space, how to choose the best method of cooling, choose between DX and chilled water systems, design and draft ducts and so on.
