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.
