How does the HRV and ERV work?

The Honeywell Whole-House Ventilation System removes stale air and replaces it with fresh air. A centrifugal blowers brings fresh air into your home from outdoors and at the same time exhausts the stale air in an equal amount. Both the incoming and outgoing air streams pass through an exchange core where the energy from the exhaust air is efficiently transferred to the incoming air. In the winter, this means that the fresh air coming into the house is warmer than the cold air outdoors. In the summer, this means that the fresh air coming into the house is not as hot as the air outdoors. Vents in your home draw the stale air into the Honeywell Whole-House Ventilation System to be exhausted outside. After the heat and energy is exchanged, the fresh air brought in through the ventilator gets distributed in the house though the ducts of your heating or cooling system.
