What is the function of the partially ducted configuration in HRVs and ERVs?

The partially ducted configuration in Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) is designed to optimize indoor air quality while addressing specific ventilation needs in a home. This configuration makes use of exhaust ducts that are strategically connected to areas such as bathrooms, kitchens, and utility rooms, where humidity and pollutants are commonly present. By removing stale or contaminated air from these specific areas, it effectively enhances air quality.

In addition to exhaust vents, the partially ducted system also facilitates the introduction of fresh outdoor air into the living areas of the home through the HVAC return ducts. This dual-function approach allows for effective management of indoor air, ensuring that fresh air is circulated effectively throughout living spaces while simultaneously eliminating pollutants from key areas. The integration of these functionalities exemplifies the efficiency of the partially ducted configuration in promoting a healthier indoor environment.

Other options do not reflect the comprehensive functionality of the system. For example, the option that states it exclusively provides heating overlooks the ventilation and air quality functions that are critical to HRVs and ERVs. Similarly, claiming that it requires no external ducts fails to recognize the necessary connections to exhaust vents. Lastly, suggesting that it solely vents air from living areas misses the intended purpose of managing air
