01About the course
What you will learn in HVAC Design
HVAC stands for Heating, Ventilation and Air Conditioning. HVAC design is the engineering work of deciding how much cooling or fresh air a building needs, choosing the right system – split, package, VRF or chilled water – and then sizing the ducts, pipes, fans and pumps that deliver it. The designer works with psychrometric charts, heat load sheets, software such as HAP and duct sizers, and AutoCAD drawings that go to the site.
This page is for learners outside Vellore, Katpadi and Ranipet – NRIs, professionals in the Gulf and other countries, and students elsewhere in India who want HVAC Design taught live by a trainer.
Basic computer use and some familiarity with AutoCAD commands will help. A mechanical background (thermodynamics, heat transfer basics) makes the calculations easier, but the course explains each concept from the start.
