Abstract [sv]

Detta arbete gick i huvuddrag ut på att undersöka uppvärmningsproblematiken på Björkö Friskola i Linköping. Uppdraget hade som huvudsyfte att finna en lösning på det kalla inomhusklimatet i skolbyggnaderna. Det ingick även att finna lösningar på problem som anläggningen dragits med sedan byggnation. Efter avgasmätning på fjärrvärmepannorna konstaterades det att en av dessa utvecklade mycket låg effekt och hade dålig förbränning. En optimering av förbränningen utfördes som resulterade i mindre pannunderhåll och mindre miljöpåverkan. Björkö Friskola stod inför ett beslut om att bygga en ny matsal, och ville ha underlag för om det var möjligt att ansluta denna byggnad till fjärrvärmen. Därför utfördes det beräkningar på om detta, rent teoretiskt skulle vara möjligt. Byggnaderna på området förbrukar vid årsmedeltemperatur cirka 27 kW och vid en utomhustemperatur på -200C, cirka 82 kW. Jämfördes detta med den installerade panneffekten som var 337 kW kunde det konstateras att anläggningen i sitt nuvarande utförande skulle klara av ytterligare en anslutning.

Abstract [en]

This diploma thesis was mainly focused to investigate the heating problems of Björkö Friskola. The assignment had as main objective to find a solution on the cool indoor climate in the school buildings. It was also included to find solutions on problems that have affected the plant since construction. Exhaust gas measurement was performed on the boilers and from those values it could be established that one boiler had extremely low effect and bad combustion. A combustion optimization was performed that resulted in less boiler maintenance and reduced environmental impact. Björkö Friskola faced a decision to build a new school canteen and has considered whether it was possible to connect this building to the district heating. Thereby calculations were made in order to decide whether this could be possible theoretically. The buildings on the area during average annual temperatures consume approximately 27 kW and during a temperature of -200C, approximately 82 kW. Compared this to the total installed boiler output that was 337 kW it could be noted that the facility in its current version could facilitate another connection.
