District Heating Driven Absorption Cooling in Hedemora and Säter (engelsk)
Abstract [en]

Hedemora Energi produces and distributes district heating in Hedemora and Säter. It is during the summer in these cities, as in the rest of the country, a low heating demand. By offering its customers district heating driven absorption cooling, this could be a way to satisfy more requests while being able to sell more heat and better use the available capacity. 

In this thesis the cooling potential in Hedemora and Säter is calculated. Furthermore, the impact of integrated absorption chillers on district heating production, as well as absorption cooling profitability for Hedemora Energi is investigated. Simulations and calculations show that the system need to be adjusted for absorption cooling by increasing the supply temperatures during the hours that they are below the requirements of the absorption chillers. In addition, the adjustments cause raised return temperatures and altered flows in the network. This results in increased fuel costs and heat losses, reduced flow revenues and reduced heat supplies from flue gas condensers. Despite this, the economic results are positive for all cases. For example, over 44 thousand SEK in annual profit after integration of absorption chillers, producing 422 MWh of cooling in Skönvik, Säter.
