The rotary heat exchanger consists of a rotating wheel with many small aluminum air ducts. The warmer extract air heats the ducts and the heat is transferred to the colder supply air. Thermal efficiency reaches 86%. Some of the moisture removed with the extract air is returned to the supply air. This can be useful in winter when the outside air is usually dry and creates problems for people, indoor equipment and electronics.
