There are multiple ways for dissipating the heat generated in a data center. System types available are all evaporative cooling; wet/dry cooling; non-evaporative cooling and hybrid. The following criteria can be used to make an informed decision: location; IT load by year; climate data; cost of electricity and cost of water/ sewer. With these criteria, a variety of simulations can be used to determine the best method of IT load heat rejection. The presentation will explore ways to determine what system or a choice of systems is best based on total cost of ownership.
