Section Scope

A Datacom Cooling Product is designed for the primary purpose of providing year-round cooling for facilities which are predominantly populated with servers, computers, networking equipment, electronic equipment, storage products and peripherals which may be mission critical:

Can be one of several configurations that include one or more of the following attributes:

• The primary efficiency rating is SCOP or iNSenCOP not SEER or EER.  
• SEER and EER are not applicable to these products.  
• Optimized for net sensible cooling with a sensible heat ratio typically > 0.90, and rating accordingly in kW of cooling.
• Application and rating points differ from comfort cooling applications.
• Some equipment contains optional humidification systems installed within the cooling unit, and may also contain heat in order to offset over-cooling that may be caused by dehumidification operation.
• Equipment that is designed specifically for the application in a data centers.

Product configurations include:

• Row based units that are either DX units including external condensers, cooling towers or drycooler heat rejection, or chilled water cooling units
• Perimeter units that are either DX units including external condensers, cooling towers or drycooler heat rejection, or chilled water cooling units
• Ceiling mounted units that are either DX units including external condensers, cooling towers or drycooler heat rejection, or chilled water cooling units
• Any of the above configurations may include “free cooling” economizers that utilize air, water, glycol or a refrigerant to provide cooling with the compressors off
• Specifically excluded are the products included in the scopes of other product sections of AHRI, room air conditioners and heat pumps.
• External units which are ducted to the data center, for example air handlers.
