PROJECT
Daikin has supplied 4 water cooled chiller units from the VZ Series to meet the cooling needs of a negative CO2 emission data center in Sweden. The data center is an interesting one as it is a negative CO2 emission facility, and it is interesting to see how Daikin technology can be beneficial for such a facility to achieve climate positive goals.
PRODUCTS
- 4x EWWH VZ
- Total cooling capacity: 4 MW
- Phase II: 8x EWWH VZ will be installed in the next phase
THE CHALLENGE
The four VZ chillers have been installed to provide chilled water used to control the temperature in the different area of the facility, as data centers usually generate a huge quantity of heat which could overheat servers and components. The main aspects in the project were reliability of the chiller units, the need for great energy efficiency levels both at full and partial load and low GWP. Especially energy efficiency and GWP were really important aspects for this project, as the data center aimed at being a climate positive facility, entirely operated on energy coming from renewable sources. With its unique location 200 km northwest of Stockholm, the data center 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 such a high level of attention towards environmental impact minimization, Daikin managed to provide technology which helped achieving the project’s ambitions.
