Canada Blower RREH Three-Way Heat Saver / Ventilator is a multi-purpose
fan designed for ventilating applications that require air
recirculation. Canada Blower reversible fan and versatile damper
control systems make a unique year-round ventilator capable of
operating in three different modes: Heat Saver Mode, Mixed Air Mode,
and Exhaust / Supply Mode.
Each Canada Blower ventilator is constructed with close tolerances
between the fan propeller tips and the orifice to maintain maximum
efficiency. The reversible, cast aluminum alloy fan propeller is
secured to the motor shaft with a split taper lock bushing. The hood of
the Canada Blower Three-Way Heat Saver / Ventilator is constructed of
corrosion-resistant, fiberglass reinforced polyester and is attached to
the fan with heavy-duty structural angle supports for added fan
stability.
Typical Canada Blower Three-Way Heat Saver Fan Configuration features:
• Hooded inlet
• Motor operated recirculating dampers
• Direct drive reversible panel fan
• Plenum section
• Prefab insulated fan curb (optional)
• Modulated supply fan damper (optional) to mix outside air with
recirculated air
• Modulated temperature control (optional) to temper recirculated air
with outside fresh air.
Buildings with high ceilings save on energy costs by using the
Three-Way Heat Saver configuration. During the winter, heated air
inside the building rises to the ceiling where it becomes trapped. Air
temperatures near the ceiling may be 5°F to 20°F higher than
temperatures at the floor in the working area. Due to convection, the
heat is transferred to the exterior side of the ceiling. This causes
the building to lose heat. To compensate for this heat loss and
maintain a uniform temperature, the building’s heating system must
continually work at maximum levels. By installing the Heat Saver unit,
the warmer air at the ceiling is recovered and directed to the working
area. As standard, the unit is furnished with recirculating dampers on
two sides of the plenum fan section. The unit recirculates the air by
inducing it through the recirculating dampers and directing it back to
the floor level. Recirculating the heated air minimizes the transfer of
heat through the building’s ceiling and reduces the energy load on the
building’s heating system. By recycling the trapped warm air, a
manufacturer can expect to save 10 to 30% on fuel bills. In areas where
high heat loads occur, the Three-Way Fan Heat Saver / Ventilator can
operate in the mixed air mode and mix the recirculated air with outside
air to maintain a comfortable working environment.
Heat Saver Mode – In the heat saver mode the unit induces warmer air
trapped near the ceiling through the recirculating dampers and directs
it downward to the working area. Recirculating the air in this way
reduces the load on the heating system by maintaining a nearly uniform
temperature between the floor and the ceiling.
Mixed Air Mode – The optional modulating fan damper control system
permits outside air to be added to the recirculated air. This is
particularly desirable in spring and fall when wide outside temperature
fluctuations can cause the heating system to override.
Exhaust Mode / Supply Mode – With the recirculating fan dampers closed,
the ventilator can be used to exhaust hot air from the ceiling area. By
reversing the fan rotation, 100 % outside air can be supplied. The
reversible fan moves the same volume of air in both the supply and
exhaust directions. The fan’s rotation is easily switched between
supply and exhaust by using the optional reversing starter.
In large rooms, it is particularly effective to use several ventilators
for summertime ventilation, using alternating units as supply fans and
exhaust fans. All Canada Blower ventilators can then be arranged
in this pattern for thorough coverage.
An integral part of Canada Blower Three-Way Heat Saver /
Ventilator is Modulating Damper Fan Control package. The Modulating
Damper Control package is designed to modulate one supply / exhaust fan
damper, mounted horizontally at the roof curb level, and two
recirculating fan dampers, mounted vertically on two sides of the fan’s
plenum section. The three fan dampers are modulated to provide the
right mix of recirculated air and outside air which reduces the heat
load on the building’s heating system, lowering the building’s energy
usage. The Damper Control package modulates the three fan dampers by
using a discharge-air temperature-sensor, controlled from a remote set
point. The dampers are modulated to maintain the temperature selected
on the remote station. Modulating the fan dampers provides the right
mix of recirculated air and outside air for supply, exhaust and
recirculating operations. The control station is furnished as a
separate part for remote mounting at the site. It houses the reversing
starter switch for starting the fan and changing direction (reversing
motor starter optional), and a temperature set point for temperature
adjustments between 40° and 90°F. A mounting fan bracket for
the discharge sensor is included for field installation at the fan
plenum discharge.
