How HRVs and ERVs work
Balanced mechanical ventilation systems use fans to simultaneously exhaust stale air and supply outdoor air in equal quantities. It is the preferred, and in many jurisdictions the only allowed, approach to ventilation. A central HRV/ERV or air exchanger continuously exhausts stale air from the bathrooms, kitchen and laundry rooms, and supplies air to bedrooms and living, dining and recreation rooms through dedicated ventilation ducts. Systems that utilise the furnace or air handler for distribution of ventilation air tend to use more energy than ventilation systems that use dedicated supply and exhaust ductwork because of the need to continuously operate the large furnace or air handler fan.
Heating can account for over 50% of annual energy consumption in houses. Since typical ventilation systems introduce unconditioned outdoor air and exhaust conditioned indoor air, there is potential for energy savings by incorporating heat transfer between the two air streams. This can work both during the winter, when warm exhaust air preheats the intake air, and during the summer, when cooler air-conditioned exhaust air pre-cools the intake air.
