The Benefits of HRVs
Flexible duct connectors should be installed
between the HRV and the galvanized ductwork.
ATTENTION
!
Heat Recovery Ventilators (HRV) are designed to supply
fresh air to a building while exhausting an equal amount
of stale air from the building. An energy savings is expe-
rienced during the process by reducing the heating (or
cooling) requirements.
HRV - Aluminum Core
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 incom-
ing fresh air with the stale air that is being exhausted.
Location of the HRV for Mounting
The HRV must be located in a heated space where the
surrounding air temperature does not fall below 60°F
(16°C). The unit must be mounted level (horizontal) to
obtain proper drainage of water from the heat exchange
element and drip pans. The warranty will be void if these
conditions are not met.
Typically, the HRV is positioned close to an outside wall
or the roof to simplify the connections and keep the
length of insulated ducting required for the fresh air in-
take to a minimum.
A minimum clearance of 30 inches (76 cm) in front of the
HRV is recommended to service the heat exchanger cores
and the filters. The HRV may be mounted on an equip-
ment platform providing the drain hoses are clear and
there is sufficient space to open the doors for servicing.
