Data center cooling
The EcoBreeze™, a modular indirect evaporative and air-to-air heat exchanger cooling solution, has the unique ability to switch automatically between air-to-air and indirect evaporative heat exchange to consistently provide cooling to data centers in the most efficient way. The design of the EcoBreeze is able to reduce energy consumption by leveraging temperature differences between outside ambient air compared to IT return air to provide economized cooling to the data center. The EcoBreeze meets ASHRAE 90.1/TC 9.9 requirements for efficiency and economization with multiple frame sizes with varying voltages and phases to address any data center’s cooling needs.
As data centers are constantly expanding and local energy companies place heavy restrictions on a data center’s ability to pull more power from the grid, there is an urgent need to reduce power consumption through energy efficiency and economization. The EcoBreeze addresses the needs of today’s data center’s by implementing multiple forms of economization into each module. The unit, located outside the perimeter of the data center, takes advantage of localized climates and can automatically switch between two forms of economized cooling:
· Air-to-air heat exchange - Brings in hot IT air in from the data center through the modules EC (Electronically Commutated) fans which is then passed through internal channels of the Indirect Evaporative Cooler (IEC). After the IT air is cooled, it leaves the IEC and passes through a cooling coil and returned to the data center.
· Indirect evaporative heat exchange - When ambient temperatures can’t support a air-to-air heat exchange cooling is done through indirect evaporative cooling which removes heat from the IT air by evaporating water on the outside of the heat exchanger channels. According to the company, EcoBreeze is the first solution on the market which prevents the outside air from coming in contact with the data center air, regardless of which cooling mode is used (air-to air or indirect evaporative).
The EcoBreeze has a proportional R410a refrigerant system as well as an onboard water treatment system which eliminates the need for chemical water treatment. This feature addresses environmental concerns associated with some refrigerant or water based systems. Both of the economization cooling strategies employed by the EcoBreeze maximize localized climate conditions to ensure the most efficient and effective form of cooling throughout the year.
The EcoBreeze is available in individual 50kw modules that can be grouped up to four modules (200kw) or eight modules (400kw) of sensible cooling. This modular, scalable approach enables customers to purchase only what they need to meet their current cooling requirements, while giving them the ability to increase their cooling capacity at any time as their data center grows. This modularity also provides redundancy at the frame level and ensures availability of the system even through maintenance and service intervals.
Power, water, air flow distribution and communication connections are centralized to the frame simplifying installation requirements. Additionally, since the unit is located outside the perimeter of the data center, the EcoBreeze takes up zero whitespace, enabling IT managers to utilize space in the data center to increase its capacity without having to allot for space to include additional cooling units.
The EcoBreeze will be available for purchase in 2011. For more information regarding APC’s cooling solutions please visit www.apc.com or call 800-877-4080.
