Organization: ASHRAE
Publication Date: 1 January 2020
Status: active
Page Count: 32
scope:

This standard applies to classes of air-conditioning units that are used to air condition data center (DC) and other information technology equipment (ITE) spaces. Such units must be able to be tested using an air enthalpy method and facilitate heat transfer across at least one heat exchanger.

Exclusions

a. Rating of individual assemblies, such as condensing units

b. Cooling heat exchangers within ITE products

c. Heat-operated equipment (e.g., adsorption and absorption devices)

d. Vapor compression variable-refrigerant flow serving multiple evaporators

e. Source cooling equipment (e.g., chiller units for either water or refrigerant)

PURPOSE

The purpose of the standard is to establish a uniform set of test requirements for rating air-conditioning units that are applied in data center (DC) and other information technology equipment (ITE) spaces.
