High Efficiency Economizer-based Cooling Modules for Large Data Centers

When a cooling plant operates in economizer mode, high energy-consuming mechanical systems can be turned off. A standardized, modular cooling plant designed to operate primarily in economizer mode not only reduces costs but also improves predictability and flexibility. This paper shows a new approach to data center cooling that uses approximately half the energy of traditional methods and at the same time provides greater scalability, availability, and ease of maintenance.
