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.

Other details:

The course can be attended by:

  • Engineering Graduates (Chemical, Mechanical, Electrical, Met & Materials)
  • Graduates of Polytechnics in the Engineering field (ND & HND)

All classes are to be delivered via online platform using popular video meeting software such as Zoom, Teamviewer or Teams.

  • Weekday (Mon - Friday): N250,000
  • Weekend (Saturday & Sunday): N275,000

 

  • How long does the HVAC Design & Drafting course take to complete?

  • This Course runs in two sections. One is for Weekday participants and the other is for Weekend participants. Weekday sessions (Mon - Fri) takes about a 5 weeks to complete. While the Weekend session (Sat - Sun) takes about 14 weekends to complete.

  • Will you learn how to carry out HVAC drafting using AutoCAD?

  • Yes, you will be taught how to draft HVAC designs using AutoCAD.
