Basic air distribution systems

A basic air distribution system includes supply air and return air.

An air distribution system should be zoned to deliver an adequate amount of supply air to the cooling air intake vents of the racks. Supply air temperature should be maintained within the following parameters:

•Ceiling supply system—From 12.8°C to 15.6ºC (55°F to 60°F)

•Floor supply system—At least 15.6°C (60°F)

If a ceiling plenum return air system or a ducted ceiling return air system is used, the return air grill(s) in the ceiling should be above the exhaust area or the exhaust row.

The following three types of air distribution system are listed in order of recommendation:

•Underfloor air distribution system—Downflow air conditioning equipment located on the raised floor of the computer room uses the cavity beneath the raised floor as a plenum for the supply air.

Return air from an underfloor air distribution system can be DRA above the ceiling.

Perforated floor panels (available from the raised floor manufacturer) should be located around the front of the system cabinets. Supply air emitted though the perforated floor panels is then available near the cooling air intake vents of the racks.

•Ceiling plenum air distribution system—Supply air is ducted into the ceiling plenum from upflow air conditioning equipment located in the computer room or from an air handling unit (remote).

The ceiling construction should resist air leakage. Place perforated ceiling panels (with down discharge air flow characteristics) around the front of the system cabinets. The supply air emitted downward from the perforated ceiling panels is then available near the cooling air intake vents of the racks.

Return air should be ducted back to the air conditioning equipment though the return air duct above the ceiling.

•Above ceiling ducted air distribution system—Supply air is ducted into a ceiling diffuser system from upflow air conditioning equipment located in the computer room or from an air handling unit (remote).

Return air from an above ceiling ducted air distribution system can be DRA above the ceiling, or CPRA.

Adjust the supply air diffuser system grilles to direct the cooling air downward around the front of the racks. The supply air is then available near the cooling air intake vents of the racks.

Air conditioning system specifications

All air conditioning equipment, materials, and installation must comply with any applicable construction codes. Installation of the various components of the air conditioning system must also conform to the air conditioning equipment manufacturer’s recommendations.
