SWEDISH MINSUN APPLICATION CASE
The reference case chosen for the MINSUN analysis Is a real project, the Lyckeho project, situated in the neighborhood of Uppsala, Sweden. The 550 houses in the Lyckebo area are heated with a separate district heating network connected to a solar heated seasonal storage in a rock cavern.
The storage, the collectors and most of the houses have been constructed between 1981-1983. In the Lyckebo project the solar collectors would consist of 30,000 m2 flat plate collectors for 100% solar energy.
This is not the real truth from the beginning as only 15% of the solar collectors are installed and the rest of the "solar energy” Is simulated with an electric boiler. The remaining solar collector area is supposed to be built when the economic situation has changed. Uppsala is situated at 60°N and the load for space heating and DHW for the 550 houses is 30 TJ/a and the peak is 3.2 MW.
