How a Chiller Plant Works ❄️ | HVAC System Explained Step by Step
Ever wondered how shopping malls, hospitals, airports, hotels, and skyscrapers stay cool even on the hottest days? ❄️
In this TatvaExplains engineering documentary, discover how a water-cooled chiller plant removes heat from buildings using chilled water, refrigerant, compressors, condensers, cooling towers, and air handling units (AHUs). Follow the complete cooling cycle from the building back to the chiller and understand how modern HVAC systems provide efficient air conditioning.
📚 In this video you'll learn:
✅ How a chiller plant works
✅ What chilled water does
✅ How the evaporator absorbs heat
✅ How the compressor works
✅ How the condenser removes heat
✅ How cooling towers reject heat
✅ How the refrigeration cycle works
✅ How commercial HVAC systems cool large buildings
