With more water-cooled IT products arriving in the marketplace, ASHRAE TC9.9 felt the need to outline some of the common processes, parts, and materials for focus in use for future water-cooled designs. Some parts in a water-cooled IT system will be specific to the product design, such as cold plates, manifolds, arrangement of piping, pumps, valves, and soon, but others such as quick connects, hoses, hose connections, materials, and water chemistry fall more into the category of common parts that can be used by all current and potential manufacturers of water-cooled IT equipment. This white paper is an attempt to provide and make available those items that could be classified as common. The material published in this white paper compliments the materials published in Liquid Cooling Guidelines for Datacom Equipment Centers, second edition (ASHRAE 2014).
