AutoDesk’s BIM software allows mechanical, electrical, and plumbing engineers to better coordinate design data and enhances collaboration between engineering and architecture teams. With this announcement, consulting-specifying engineers now can access more than 3,000 files related to the Liebert CW, which were added in 2011, as well as the newly-added Liebert DS, to assist with development of data center designs. Floorstand and plenum files also are available. BIM-enabled AutoDesk Revit models are becoming a standard within the data center design community.
The Liebert DS, a refrigerant based direct expansion (DX) computer room air conditioning unit, uses the industry leading Copeland Scroll Digital variable capacity compressor technology as its primary method for cooling. It is available in upflow and downflow configurations and in cooling capacities up to 105 kW. The Liebert CW, a chilled water-based computer room air handling unit, uses the building chilled water supply as the cooling source. It also is available in upflow and downflow configurations and in cooling capacities up to 400 kW.
The Liebert CW and Liebert DS both are available with optional electrically commutated (EC) plug fans and utilize the Liebert iCOM control system that enables multiple control algorithms depending upon the type of sensors connected. The intelligent control capabilities enable data center managers to tune their cooling systems to dynamically adjust airflow patterns by controlling the speed of the EC plug fans to allow cooling unit capacities to adapt quickly to changing room conditions.
