Solution
TVD Free-Cooling chillers and TRF CW perimeter units for high-efficiency chilled water systems
HiRef provided a complete cooling solution for a Data Center in Riihimäki, Finland, designed to ensure high standards of reliability, energy efficiency, and operational continuity. In line with these objectives, a chilled water system was selected, as it represents an ideal solution to optimize thermal load management and maximize overall system efficiency. The solution was developed to meet the needs of modern IT infrastructures, where stable operating conditions are essential to protect equipment and ensure service continuity.
The supply
Cooling production is ensured by 2 TVD chillers, each with a capacity of 400 kW, equipped with an indirect free-cooling system that allows the exploitation of low outdoor temperatures typical of the Finnish climate, significantly reducing overall energy consumption.
The units feature microchannel coils and use low-GWP refrigerant R1234ze, in compliance with the latest environmental regulations. The configuration with dual screw compressors, each managed by a dedicated inverter, enables precise cooling capacity modulation, optimizing performance even under variable load conditions.
For indoor climate control, 4 TRF CW perimeter units with a capacity of 200 kW each were installed, designed to ensure accurate control of thermo-hygrometric conditions. The units adopt a displacement air distribution system, ensuring uniform airflow diffusion. They are also equipped with a two-way modulating valve, smoke and fire sensors for maximum safety, a fast restart system in case of blackout, and an integrated condensate pump.
Thanks to this project, HiRef confirms its expertise in developing high-efficiency solutions for Data Centers, combining advanced technologies, environmental sustainability, and operational reliability. The system, with a total cooling capacity of 800 kW, represents a concrete example of how high performance and energy optimization can be achieved, especially in climatic conditions particularly favorable for the use of free-cooling.
