Kyla på Swedavia Stockholm Arlanda
Kartläggning av nuvarande fjärrkylasystem och framtida utvecklingsmöjligheter
Arlanda airport is Sweden?s largest airport. The demand for comfort cooling of the airport?s buildings is high and is mainly provided by district cooling. District cooling is based on the same principle as district heating. A centralized production facility for the district cooling offers advantages from both an environmental and operational perspective. Swedavia, which owns, operates and develops the airport, therefore advocates that district cooling always should be the first hand choice to meet the demand of comfort cooling. In the current situation the district cooling system at Arlanda is operated at its full capacity. This makes additional connections impossible. The purpose of this thesis has been to examine the possibilities of increasing the deliveries of comfort cooling through Arlanda Airport district cooling system. This report describes Arlanda airport?s district cooling system and its development prospects. District cooling requires a system perspective. It is important that all components in the system interact to achieve an optimized use of the distributed cold water. In addition this report also addresses the parameters that affect a building's cooling load and the measures that can reduce the power load, which is the main parameter that limits the number of users on the district cooling network.
