What is the fully ducted configuration in ventilation systems?

The fully ducted configuration in ventilation systems is characterized by the use of exhaust ducts connected to grilles located in various spaces, such as bathrooms, kitchens, and laundry rooms, to effectively remove indoor air pollutants. This configuration also incorporates supply ducts to bring in outside ventilation air, ensuring a balanced exchange of air within the building. By using multiple ducts strategically placed throughout the home, this system can enhance indoor air quality by removing stale air and introducing fresh air, while also allowing for targeted ventilation in areas that typically generate higher levels of pollutants, such as cooking and bathing.

This approach is advantageous as it allows for a controlled ventilation strategy, which can be adjusted based on the specific requirements of different rooms. Unlike configurations that rely solely on a single exhaust duct, which may not efficiently manage the air quality in various parts of a home, the fully ducted system optimizes air movement and enhances comfort levels.

The other choices do not capture the complete essence of a fully ducted configuration. For instance, a single exhaust duct does not provide the comprehensive air management offered by multiple connected ducts, and natural airflow systems lack the mechanical assistance and precision of fully ducted systems. Additionally, the assertion that it only operates in residential buildings is also inaccurate, as fully ducted
