(Pumped) Distributed Refrigerant Cooling - Standardized Infrastructure
|Publication Date:||1 January 2014|
This standard is part of a suite of standards supporting the installation design and material selection of distributed cooling systems for electronic equipment. More specifically, this standard addresses material and connectivity specifications for the deployment of a universal distributed R134a refrigerant infrastructure. DRC systems are typically comprised of three (3) primary common elements: 1) Thermal transfer system - Refrigerant pumping unit; 2) refrigerant distribution infrastructure; and 3) close-coupled cooling units.
Unless otherwise specifically identified, this standard supports refrigerant systems incorporating R134a as the refrigerant utilized in the distribution infrastructures between the pumping unit and close-coupled cooling units.
The purpose of this standard is to provide support for the deployment of a universal application infrastructure for Distributed Refrigerant Cooling (DRC) systems. The universal application allows for the installation of a single, common infrastructure that is adaptable to support multiple vendors of DRC. This infrastructure may be designed and installed within an equipment area prior to the placement of equipment and racking, without specificity of the DRC vendor. This early placement may reduce overall installation costs and provides for more rapid deployment equipment build-outs in the supported space. The standard also provides for a designation of standard R134a refrigerant infrastructure interface(s) or port(s). This commonality provides manufacturers of equipment-specific standards and specifications for connectivity to the core refrigerant infrastructure. For the purposes of this standard, the primary cooling loop (e.g., chilled water, DX, etc.) is not included.
