Induction Units
Carrier was a pioneer in the development of induction
unit systems. With the advent of the high-rise buildings in the
1950s and 1960s engineers discovered that by utilizing high-pressure,
cold air they could reduce the required space for ductwork and
air handling units. By using high-pressure, cold air smaller
ducts and smaller fans could be used, thereby saving valuable
interior space. By "inducing", hence the name induction
unit, room air and mixing it with cold primary supply air, a mixed
air temperature of around 65-degrees (F) could be delivered to
the space. This meant less complaints by tenants from cold drafts.
The primary supply air is cold and de-humidified
to a point where all of the latent cooling load from the outside
air and the room is handled by the primary air. The remaining
room sensible cooling load is handled by inducing room air across
a secondary chilled water cooling coil. Since the secondary cooling
coil is sensible only duty it runs "dry" with little
or no condensation. This saves additional installation cost by
eliminating the need for condensate piping and drains. Optional
heating coils are available for either hot water, (2-pipe or 4-pipe),
or electric resistance heat.
Induction units modulate cooling capacity by reducing
the volume of cold primary air coming from the central station
air handling unit while simultaneously inducing room air to maintain
a relatively constant volume of supply air to the room. Induction
units may be located against an outside wall or are sometimes
located above the ceiling to recover heat from the lights (reducing
the need for reheat) and provide humidity control, ventilation
and cooling.
Provisions should be made for morning warm-up and
nighttime heating. Induction units located along perimeter walls
may be operated at night as convection heat units since the primary
air will be de-energized. There are various systems alternatives
to help meet specific application requirements.
