HVAC (Design and Drafting) Course.(Heating Ventilation & Air Conditioning)

Basically this course is design for mechanical engineer or for those student who want to work in HVAC industries.

We know that HVAC Design & Drafting course helps you core domains like Design and Drafting systems

This Course enables the entry level and working engineers to understand the basics, different systems used in Air Conditioning for Domestic and commercial purposes.

To achieve the optimal design, one should needs good analytical skills and up-to-date technical knowledge of various system designs. This training is useful to design HVAC Systems. This training is an opportunity to apply the academics and develop an understanding of how to develop solution-driven concepts and translate them into a complete set of plans and prototypes.

HVAC Required in Commercial Buildings, Airports, Shopping malls, Petrochemical complex, refineries, pharmaceutical industry, Aerospace industry, Hospitals etc..,

Here is the Qualification Required For HVAC Design and Drafting Course.

B.Tech (Mechanical Engineering)

Diploma (Mechanical Engineering)

ITI ( Refrigeration and Air-Conditioning)
