District cooling

District cooling

We offer district cooling services across the entire chain – production, distribution, and substations.

Production

District cooling is primarily produced using free cooling from lakes or the sea, along with chillers. It is often cost-effective to balance daily demand variations with thermal storage. We support energy companies in Sweden and internationally in developing their district cooling operations.

In some cases, the condenser heat must be released into the environment — into air or water — but often it can be recovered, either directly or with the help of heat pump technology, into a district heating network. Combining district cooling and district heating in the same facility is an elegant and profitable design.

Distribution

Pipelines

There are many similarities in designing networks for district cooling and district heating, but also some differences. For the same output, pipe dimensions are larger in district cooling, thermal forces are lower, and so on. Otherwise, our approach remains the same.

Pumping stations

Pumping stations are typically designed in 3D as standard. With our experience from production facilities, we handle all aspects of a pumping station.

Utility coordination

Most larger projects require utility coordination. We also offer this service separately, regardless of whether district cooling is included in the project or not.

Substations

The district cooling substation marks the energy company’s physical boundary with its customers. Usually, the property owner is responsible for the installation and operation of these units, with or without assistance from the energy company. Regardless, we offer design, construction management, project management, and inspection of the installation, as well as commissioning and system balancing. We also assist in fine-tuning existing substations to achieve optimal energy efficiency. The low temperature difference between supply and return lines in district cooling makes these substations particularly sensitive to malfunction.
