District cooling system in Šaleška Valley

District cooling system in Šaleška Valley Velenje,
Saleska, SloveniaPDF Summary
The subject of our application is a district cooling system in the city of Velenje, Slovenia. There the cooling energy is produced in absorption chillers. The heat for their operation is supplied from an existing district heating system. In it the supply temperatures are sufficient to power the absorption chillers through the whole year, due to industry consumers. The heat source for the district heating system is surplus heat from a power plant. The system is facing problems with low energy and economic performance in the summer months due to relative low heat demands by consumers. As a consequence an opportunity was recognized to use the heat from the distribution network to power the absorption chillers and by doing so improving the distribution network performance, as well as producing cooling energy from surplus energy, instead of using the electric energy for the electro-compressor technology. Thus there are several direct and indirect benefits to the community in the area where the system is in operation.
