What Are HRVs ?

To understand these products and
their functions, here are a few things
to remember.
Heat Recovery Ventilators (HRVs)
are recommended for colder areas of the
country that have longer heating seasons
as well as drier desert areas of the South.
Heat Recovery Ventilators are complete
whole house ventilation systems that
incorporate a supply motor and an
exhaust motor in one unit. The supply
motor draws fresh air in from the outside
and the exhaust motor pushes stale con-
taminated air out. The two air steams are separated by a heat/ ener-
gy recovery core which tempers the air making it the most comfortable solution for a
healthy indoor environment.
For information on how these units can help you save energy and lower heating or
cooling costs, read "How Do They Work".

How Do They Work?

Heat Recovery Ventilators (HRVs)
An HRV is designed to bring a continuous sup-
ply of fresh air into a home while exhausting an
equal amount of contaminated air. HRVs use
what is called a "sensible" heat recovery core.
This special aluminum core transfers heat from
the exhaust air stream to the incoming air
stream. Fresh incoming air is tempered by the
heat that is transferred from the outgoing air so
you save on energy costs. Fantech HRVs are
equipped with automatic defrost mechanisms
so even if you live in the coldest climates you
can use your HRV all year long.

Port Configurations

Five Port Models feature motorized
damper for recirculation mode and defrost.
Positive shut off of supply port when unit is
in standby.
Four Port Models provide constant ventila-
tion even in defrost mode without the need
for additional parts. An exhaust only (fan
shut down) defrost strategy is an effective
method at an affordable price.
