Småskalig säsongslagring av solenergi för uppvärmning av bostäder

Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

Masteruppsats · Karlstads universitet

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when …

Expansionsmaskiner istället för strypventiler - en effektivisering

Examensarbete, avancerad nivå · Uppsala universitet

… valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure …
