Replacing data centre cooling infrastructure in a 24/7/365 telecommunications environment takes great care, but with existing units bordering on 20 years old, it was time to upgrade and ensure a safe transition without downtime. The new are projected to reduce energy costs by 69% per year. SITE’s expertise in mission critical data centres and offshore projects meant the customer could be confident of a smooth delivery and no break in customer services.
The installation consisted of three indoor Multi-DENCO® DMF065D Downflow Air Conditioning units each providing 59.7kW net sensible cooling. The Multi Denco range operates under typical conditions with a sensible heat ratio (SHR) of 1.0. The enhanced “energy efficiency” in the Multi-DENCO precision climate control systems are achieved by optimised use of the internal inverter compressor, EEV and fans. The inverter drive controls the refrigeration compressor variably and steplessly adapts the unit’s output to the cooling demand and results in “high energy efficiency” especially in partial load operation.
Chris Wellfair, Projects Director at Secure I.T. Environments, added: "The advances in data centre cooling equipment deliver substantially improved energy efficiency and a rapid return on investment. These projects should be seen as investments in resilience and reduced operational costs, and delivered with the right partner, can take place with no brakes in service and minimal disruption.”
