District cooling is becoming increasingly important worldwide and district cooling plants are also being built in Denmark. The basic principle of district cooling is similar to that of district heating. A carrier liquid is cooled centrally and then the cold is distributed to the consumer through a pre-insulated piping system.
Centralised cooling produces a more cost-effective system than cooling in smaller local units. Put simply, you get more cooling for your money. Often different energy sources can be used that would otherwise go to waste, such as waste heat from power generation or industrial processes. Other heat sources such as waste incineration and geothermal energy can also be converted to district cooling.
In district cooling systems, the working temperature is typically between 6 °C and 12 °C. However, cooling liquids with extremely low temperatures, for example in the chemical industry, can also be transported.
In addition to pre-insulated district heating pipes and components for district heating plants, isoplus also supplies pre-insulated pipe systems for district cooling. Flexible piping systems can reduce installation costs. For larger district cooling plants, fixed piping systems are recommended. Our experience of insulating district heating pipes ensures minimal energy loss from the piping system.
