“After two years of operation, the actual efficiency of our data center in Keflavik,
The solution developed for Verne Global incorporated complex algorithms to provide the correct levels of cooling without using mechanical cooling. The task involved taking full advantage of the ambient air conditions and designing the required parameters. The end result was an N+1 cooling system customized with primary cooling being supplied by direct free cooling from the outside air. Each unit has multiple variable speed electronically commutated fans to precisely match airflow to the cooling demand in order to further reduce energy use and provide N+1 resilience.
The system and its controls help ensure that temperature levels in the data center are maintained at 18°C to 27°C (64.4°F to 80.6°F) with humidity between 30 and 70 percent relative humidity by the primary system of direct free cooling. Secondary cooling is via indirect free air with a glycol heat exchanger. Since the opening of the data center, Verne Global has used 100 percent free cooling in either direct or indirect mode. This cooling system efficiency contributes to the data center’s impressive overall PUE (Power Usage Effectiveness) that has been tested to 1.21.
A unexpected bonus benefit of the cooling system‘s efficiency was discovered by the data center operations team after the system was operating for some time. “We learned that our customers are becoming more efficient at the IT level. Due to the efficiency of the fan sizing and the pressures we can get an extra degree of cooling and for that one extra degree of cooling, our customers’ servers are operating more efficiently,” Cantrell explained.
“With customers such as Verne Global committed to seeking out and using renewable energy, the CES Group Data Center Products team is helping lead the way in developing innovative solutions that enable data centers to deploy cooling strategies and make a significant environmental contribution,” said
