Simulation Results of High Solar Fraction Combi-Systems in Different European Locations Using TRANSOL 3
Abstract
The current work presents and analyzes the results of simulations using the software TRANSOL 31 for high solar fraction combisystems in three different European locations. The main work aim is to examine the potential of high solar fraction configurations in energy and economy terms. Dimensioning criteria that result to sound economies are chosen and compared among typical small/medium residential buildings of three different locations in Greece, Italy and Germany. Simulation results (solar yields) and some economy aspects are presented under the selected dimensioning criteria. Solar fractions up to 50% are achieved. Additional prices in some cases of well insulated houses are lower than 60€ per m2 of house living area. However, payback times often result high and the need for price reduction is evident. Moreover, some interesting characteristics of the simulation procedure are briefly described. Finally, an advanced combisystem configuration (in combination with a reversible sorption heat pump) is introduced as an issue for further analysis.
