American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) has revised its standard for rating liquid coolers. ANSI/ASHRAE Standard 24-2000, Methods of Testing for Rating Liquid Coolers, supports ARI Standard 480. The standard establishes:

  • Testing requirements.
  • Minimum data requirements for publishing ratings.
  • Marketing and nameplate data.
  • Conformance conditions. The standard is intended for use by companies that produce evaporator heat exchangers. According to Shane Moeykens, chair of the committee that developed the standard, it addresses how actual testing to determine performance ratings will be performed.

    To order a copy of Standard 24, call (800) 527-4723; fax (404) 321-5478; or visit www.ashrae.org. The cost of the standard is $20.
