  3. Ⅰ. How it works? It provides a controlled way of ventilating a home while minimizing energy loss. ■ In The Winter, It reduces the costs of heating ventilated air by transferring heat from the warm inside air being exhausted to the fresh (but cold) supply air ■In the summer, the inside air cools the warmer supply air to reduce ventilation cooling costs Polluted & High Humid Air Polluted Cold Air Element Heat Heat Heat Heat Moisture Moisture Indoor Outdoor Element Moisture Moisture Moisture Heat Heat Heat Heat Heat Moisture Element Filtered & Fresh Air Cold & Dry Air
