Ensuring Availability and Reliability with Innovative Technology AVAILABILITY Business-critical systems demand availability and capacity. However, to keep costs down, data center managers must constantly strive to maximize efficiency in their infrastructure equipment. The Liebert DSE precision cooling system utilizes innovative equipment that is designed to ensure reliability and performance while operating at the industry s highest efficiency. The Liebert DSE can create savings of 70% or greater compared to traditional perimeter precision cooling systems at the design-day rating point. The Liebert DSE uses the following primary innovations to ensure efficiency, availability and capacity: Tandem digital scroll compressors EC plug fans Staged evaporator coil Electronic expansion valves Liebert EconoPhase Pumped Refrigerant Economizer Liebert icom control Micro-channel coil condenser with intelligent EC fans 1 1 Liebert EconoPhase Pumped Refrigerant 2 Economizer (Air models only) The air-cooled Liebert DSE precision cooling system is available with an optional Liebert EconoPhase pumped refrigerant economizer, which uses cooler outdoor temperatures to enable free-cooling. This is a fluid economizer that utilizes the system s R410 refrigerant as the fluid in the same evaporator/ condenser coils as normal operation. The two-phase characteristic of the fluid is over 9 times better at transporting heat as the glycol mixtures typically found with compressorized solutions. The lack of need for a special econo-coil also saves evaporator fan energy. This revolutionary economizer makes the Liebert DSE with Liebert EconoPhase more efficient than a Chiller Plant with a series free-cooling heat exchanger, and it is also more efficient than an air economizer freecooling system. This higher efficiency is gained while also eliminating the risks and maintenance issues faced by other free-cooling approaches. 3 4 5 Electronic expansion valves, used in place of mechanical thermal expansion valves, enable operation at lower condensing temperatures, which reduces compressor power and improves efficiency. EC Plug Fans are designed to function optimally both in the unit and under the floor. This makes the Liebert DSE system a great fit for both raised floor and non-raised floor data centers. EC Plug Fans operate at variable speeds, ensuring that performance is matched to load for the greatest efficiency. Staged evaporator coils provide greater efficiency when only one circuit of cooling is required. Tandem digital scroll compressors reduce power consumption as as cooling capacity is modulated. This allows the Liebert DSE highefficiency precision cooling system to consume the proportionate amount of power for the load. 6

6 Optimize efficiency and reliability with the Liebert icom Control The Liebert icom control, integrated into every Liebert DSE, ensures that all cooling units in a data center are operating together intelligently to achieve maximum efficiency. The control monitors temperature and humidity levels throughout the room, calculating the most effective way to optimize operation and efficiency. With the Liebert icom control, you can take advantage of: Energy savings using dewpoint humidity control Enhanced system reliability through built-in lead/lag functions Unit-to-unit communications with teamwork settings to keep multiple units working together to optimize energy efficiency Precise control of temperature and airflow in the cold aisle that easily adapts to facilities with and without aisle containment. 7
