HVAC Design Basics

Heating, ventilation, and Air Conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. HVAC designing goal is to provide thermal comfort and acceptable indoor air quality. HVAC designing is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. We are offering Live online Training of HVAC designing, Drafting, Estimation & Installation by Experienced faculty within depth knowledge of HVAC (DDEI) and also offer software to candidates & its usage on the projects.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
