SHANTHI AIRCOOLER IN TIRUPUR A duct air cooler is a type of air cooling system designed to provide cool air through a network of ducts. Unlike traditional air conditioning units that use refrigerants, duct air coolers generally use evaporation to lower air temperature. Here's how they typically work: 1. **Air Intake**: Warm air from the environment is drawn into the cooler. 2. **Evaporation**: The air passes over water-saturated pads or filters, which cools the air through the evaporation process. 3. **Distribution**: The cooled air is then distributed through ductwork to different rooms or areas. These systems are often used in larger spaces or buildings where centralized cooling is needed. They are more energy-efficient than traditional air conditioning systems but are generally best suited for dry climates where evaporation can effectively cool the air.
