Daikin has supplied 4 water cooled chiller units from the VZ Series to meet the cooling needs of a data centre in Sweden.
The data centre it is a negative CO2 emission facility, which is why Daikin technology was selected for its advanced energy efficiencies and contributed to the facility achieving its climate positive goals.
The VZ chillers were selected for their reassuring reliability and their advanced energy efficiency levels both at full and partial load and low GWP.
- 4x EWWH VZ
- Total cooling capacity: 4 MW
- Phase II: 8x EWWH VZ will be installed in the next phase
The four VZ chillers provide chilled water used to control the temperature in the different areas of the facility, to negate the risk of servers and components overheating.
Energy efficiency and GWP were really important aspects for this project, to achieve a climate positive facility, entirely operated on energy coming from renewable sources.
With its unique location 200 km northwest of Stockholm, the data centre has access to nearby wind farms and hydropower plants, which generate very low CO₂ emissions.
The site is connected to a city’s CHP (Combined heat and power) plant and thanks to a unique solution, the generated heating is used to heat surrounding properties.
For such an innovative facility, with a high level of attention towards environmental impact minimisation, Daikin managed to provide technology which helped to achieve the project’s goals.
Daikin’s VZ Series fully met the needs of the project thanks to the incredibly high efficiencies offered – possible thanks to the screw inverter compressor, fully optimised to guarantee the best performance with HFO refrigerant R-1234ze, which also ensures very low GWP (7).
The Daikin inverter technology directly integrated in the compressor helped to ensure even greater performance of the compressors, especially at partial load, allowing the chillers to perfectly match the varying cooling capacity demands of the facility.
