Kao Data is a wholesale colocation data center located in the UK. The first of four data centers planned by the company is designed to sustainably support high-performance computing and intensive artificial intelligence. According to a new white paper from Future Facilities, Kao Data was determined to design its data center to be as energy efficient as possible. One of the ways the company achieves this goal is through the use of an indirect evaporative cooling (IEC) system, which “has been adopted to create a data center that’s greener, as well as more efficient and cost-effective to operate. “.

The company turned to computational fluid dynamics (CFD) simulations to ensure that the IEC system would meet the needs of a data center that caters to “increasingly high-density deployments characterized by machine learning and deep learning workloads and delivering the ultimate in Open Compute – Infrastructure Ready (OCP). The company used CFD simulations to test various scenarios for the external and internal environments around the data center campus.

The main objectives of the project were to define an effective IEC arrangement, analyze the air segregation solution and assess whether appropriate IEC air intake conditions were expected. – Future Installations, “Using Simulation to Validate Cooling Design”

One simulation involved changes in wind speed and direction and their impact on the airflow around the building. “The goal was to understand which wind directions caused the worst air recirculation and how best to optimize the installation to prevent moisture from being trapped around the building and reintroduced into the IECs.” Kao Data also used CFD modeling to configure its white spaces and validate thermal performance.

The document outlines data center specifications and provides an overview of the unique features of IEC systems, which are designed for data center environments. The article then explores why CFD simulation was critical to the success of the project and how they are currently using simulations.
