A duct air cooler, also known as a ducted air cooler, is a type of air cooling system designed to provide cool air through a network of ducts. Unlike portable or window air coolers, a duct air cooler is typically installed as a central system that channels cool air to different areas of a building or home through ductwork. Key features of a duct air cooler include: 1. **Centralized Cooling**: It provides a consistent cooling effect across multiple rooms or spaces from a single unit. 2. **Air Distribution**: Air is distributed via ducts, which can be adjusted to control airflow in different areas. 3. **Energy Efficiency**: Often more energy-efficient than traditional air conditioning systems, as it uses evaporative cooling to lower temperatures. 4. **Installation**: Requires professional installation and integration with existing ductwork or the installation of new duct systems. These coolers are especially useful in large spaces or buildings where individual room coolers might not be practical.
