How do heat and energy
recovery ventilators work?
While today's energy-efficient homes do a great
job of keeping heated or cooled air in, they also seal in stale,
recirculated air. A ventilating system solves the problem of stale
air by bringing fresh air into tightly constructed homes without
wasting precious energy. Heat Recovery Ventilators recover heat
energy during the heating season; Energy Recovery Ventilators
recover both heating and cooling energy year-round.
Every home contains a certain amount of
unhealthy gases from a variety of sources - building materials,
the earth under your home, your heating and cooling system, and
even people, who breathe out carbon dioxide. The easiest way to
get fresh air into your home, of course, is to fling open a
window. The problem is that you lose expensive heated or cooled
air in the process.
A ventilator allows your home to
"breathe" by bringing healthy, fresh air inside in a
controlled way. Before it removes stale air from your home, it
also recovers much of the heat or cooling energy through the use
of a heat exchanger. Then, it transfers that heat or cooling
directly to the fresh outdoor air it draws in. Best of all, the
ventilator does this without ever mixing the two air streams. The
incoming air stays fresh. And you maintain your heating or cooling
system's energy efficiency.
Bryant ventilators are controlled by a
convenient wall-mounted control unit, and have three comfort
modes. The recirculation mode recycles indoor air continuously and
exchanges air only when humidity exceeds the desired level. This
setting allows homeowners with baseboard heat to enjoy the
advantages of a forced-air heating system. In the continuous mode,
the unit replaces indoor air with fresh outdoor air 24 hours a
day. The intermittent mode provides the greatest economy, with the
unit turning on only when humidity levels exceed the desired
level.
Making a ventilator part of your home comfort
system is like being able to open a window in every room even on
the hottest or coldest days ... without the drafts, the humidity
or the high energy costs. It's literally a breath of fresh air.
