Introduction
These Heat Recovery Ventilators (HRVs) are designed
for commercial and industrial applications to provide
fresh air to a building while exhausting an equal
amount of stale air. During the winter months the
incoming cold fresh air is warmed by utilizing the heat
recovered from the stale air before it is exhausted to
the outdoors. During summer months when the indoor
space is air conditioned, the Heat Recovery Ventilator
will help in cooling the incoming fresh air with the stale
air that is being exhausted.
