MSBTE K Scheme – Heating
Ventilation and Air Conditioning (HVAC) Notes PDF
Heating
Ventilation and Air Conditioning (HVAC) under the MSBTE K Scheme is
a vital subject for mechanical and allied diploma students. It deals with the science
and engineering of maintaining indoor comfort, by controlling temperature,
humidity, air quality, and ventilation. HVAC systems are the backbone of
modern residential, commercial, and industrial buildings, ensuring a healthy,
safe, and energy-efficient environment.
The subject
combines knowledge of thermodynamics, fluid mechanics, heat transfer, and
refrigeration. With the growing importance of energy conservation and
green building technologies, HVAC engineers are in high demand worldwide.
