HVAC Design

This course deals with the HVAC system design. Through the classroom instruction, the students will be exposed to various aspects of HVAC system design, including system selection, calculations, system layout, drafting, specifications, and working procedures in this field. The use of computerized load calculation will also be covered.

This course will focus on practicality. The students without previous HVAC education but with an engineering background can become competent HVAC designers, provided they finish the course and practice with sample projects.  The course is also of value to those who already have Canadian experience but want to broaden their knowledge base to meet future challenges.

The principal target of employment is design engineer in mechanical consulting firms. Other employment opportunities are also possible.

Those who take the HVAC design course are also encouraged to take plumbing and fire protection design course because they are all responsibilities of a well rounded mechanical designer.
