(WEB HOST INDUSTRY REVIEW) — Data center cooling solutions provider Core4 Systems (www.core4sys.com) announced on Monday it has introduced its new computer room air-conditioning, air-handling units and chiller systems.
Core4′s new data center cooling systems come at a critical time, as data center energy consumption is projected to nearly double to 120 billion KWh by 2011, according to the Environmental Protection Agency (www.epa.gov).
At this rate, energy consumption is forecast to continue doubling in the next five years.
Since 40 to 60 percent of this annual energy spend is consumed by cooling systems for IT equipment, Core4′s data center cooling technologies is in high demand.
The solutions can achieve average PUE’s as low as 1.25 under the current standard for data center operation.
This is significantly low when considering that the typical data center cooling systems are averaging a PUE of 2.25, says the Uptime Institute.
Core4 says that the new data cooling retrofit should decrease their energy costs from $.44 per ton hour to less than $.11 per hour.
Many systems use airside economizing solutions which use more energy, require additional consumable expenditures for filters, and do not provide consistent temperatures and humidity levels.
Instead, Core4 systems uses refrigerant side economizing that can lower refrigeration compressor energy by up to 100 percent.
The system also deploys RSE directly in the return air and is based on the outside wet-bulb temperature rather than dry bulb temperature relied upon by ASE.
This process increases economizing hours by as much as 50 percent when compared to airside economizing and typical waterside economizing.
Core4′s new solutions also reduces water usage onsite at data center facilities at regional power plants.
“Despite the fact that fast growing data centers are emerging as one of the biggest energy consumers in any industry, relatively little attention has been paid to the impact cooling solutions have on annual energy spending,” says David Nurse, president and COO at Core4 Systems. “With today’s announcement, we are breaking down the barriers to understanding problems associated with data center cooling while introducing an elegant solution that delivers a radical improvement over legacy approaches.”
