NORWAY: Daikin has supplied 71 EWFH-TZ D air-cooled free-cooling chillers, 330 fan units and eight control systems for Norway’s largest data centre in Hamar.
Green Mountain’s OSL-Hamar is the largest data center in Norway and supports TikTok as its sole tenant.
The construction of OSL-Hamar included a state-of-the-art infrastructure with significant installed capacity and an average Power Usage Effectiveness (PUE) of 1.2, setting a new standard in the industry.
The facility currently consists of three main buildings, each equipped with 30 MW of IT capacity, and runs entirely on renewable energy from multiple hydroelectric plants.
The OSL-Hamar data center is cooled using a water-based system, where free-cooling chillers feed chilled water to fan arrays. The average temperature in the area is 5.8°C. July is the hottest month of the year, with an average temperature of 16.8°C.
EWFH-TZ D air-cooled free-cooling chillers are equipped with screw compressors, variable frequency drives and built-in active harmonic filters.
Daikin’s Variable Frequency Drive is refrigerant cooled, meaning it can operate in any environment without being affected by temperature, dust or humidity.
Designed and manufactured by Daikin, screw compressors use a single main screw meshing with a star-shaped rotor to create a compression cycle that matches the volume. Because the main rotor is balanced in both the radial and axial directions, the compressor bearing is said to have extremely high reliability.
Daikin’s Active Harmonic Filter mitigates harmonic distortion by continuously monitoring the electrical system and dynamically adjusting it to filter out harmonic distortion. This reduces total harmonic distortion to less than 5%. The filter is cooled by the refrigerant, allowing it to operate effectively in a variety of environmental conditions without being affected by ambient temperature, dust or humidity.
The Daikin Intelligent Data Centre Manager uses artificial intelligence and machine learning to optimise data centre operations. The system continuously monitors the unit’s sensors, adjusting operating parameters in real time to ensure efficient and reliable operation. It can also quickly adapt to changes in demand, improving the overall efficiency of the data centre.
Daikin Pro-W fan array units are designed using a modular approach, allowing for easy scalability and redundancy. They can be stacked or positioned directly opposite each other without compromising airflow, making them suitable for large and hyperscale data centre installations. The use of EC fans ensures high efficiency and low energy consumption.
Pro-W units feature advanced control systems that allow precise adjustment of fan speed and cooling output, ensuring cooling is always tailored to your needs.
The compact design of the Pro-W units allows for flexible installation in a variety of data center layouts, maximizing space efficiency and improving airflow management.
Daikin supplies equipment from its four application development centres in Italy and the UK: chillers and screw compressors from Ariccia (Rome), Italy; variable speed drives for screw compressors and harmonic filters from Vicenza, Italy; fan grilles from Settala (Milan), Italy, and Cramlington, UK.
