Heating, ventilation, and air conditioning (HVAC ) systems use
advanced technologies to regulate temperature, humidity, and indoor air
quality in residential, commercial, and industrial buildings, and in enclosed
vehicles. Its goal is to provide thermal comfort and remove contaminants from
the air. HVAC system design is a subdiscipline of mechanical engineering,
based on the principles of thermodynamics, fluid mechanics, and heat transfer.
Modern HVAC designs focus on energy efficiency and sustainability, especially
with the rising demand for green building solutions.
