HVAC
HVAC (Heating, Ventilation, and Air Conditioning) in mechanical engineering is essential for maintaining indoor air quality, thermal comfort, and energy efficiency in residential, commercial, and industrial buildings. Heating systems, including boilers, furnaces, and heat pumps, regulate indoor temperature during cold seasons, while air conditioning units and chillers provide cooling in warmer climates. Ventilation systems ensure proper airflow, removing contaminants, humidity, and excess heat to maintain a healthy environment. Modern HVAC systems incorporate energy-efficient technologies like variable refrigerant flow (VRF), heat recovery ventilation, and smart thermostats for optimized performance. Advanced air filtration systems, such as HEPA and UV purification, improve indoor air quality by eliminating dust, allergens, and pathogens. Proper HVAC system design reduces energy consumption, operational costs, and carbon footprint. Regular maintenance, including duct cleaning and refrigerant checks, extends system lifespan and ensures consistent performance. As sustainability gains importance, HVAC systems now integrate renewable energy sources like solar and geothermal heating for eco-friendly climate control solutions.
