Aluejäähdytys

Aluejäähdytys, meaning district cooling in English, is a centralized system for providing cooling to multiple buildings within a specific geographic area. Similar to district heating, it involves a central plant that produces chilled water, which is then distributed through a network of underground pipes to individual buildings. These buildings then utilize the chilled water to cool their interior spaces through air handling units or fan coil units.

The primary advantage of aluejäähdytys is its energy efficiency. Centralized cooling plants can often operate at higher efficiencies than individual building cooling systems, especially when utilizing advanced technologies like absorption chillers powered by waste heat or renewable energy sources. This can lead to significant energy savings and reduced greenhouse gas emissions. Furthermore, it reduces the need for individual cooling equipment in each building, freeing up valuable space and simplifying maintenance.

Aluejäähdytys systems are particularly well-suited for densely populated urban areas, business districts, and university campuses where there is a high demand for cooling. The initial investment in the infrastructure can be substantial, but the long-term operational cost savings and environmental benefits make it an attractive option for sustainable urban development. The design and operation of aluejäähdytys systems require careful planning to ensure reliable and efficient delivery of chilled water to all connected customers.
