Sensitivity Analysis of the New Sizing Tool “PISTACHE” for Solar Heating, Cooling and Domestic Hot Water Systems☆

The present paper studies the sensitivity analysis of the new PISTACHE tool's prediction performance and its input parameters. This work is a part of the R&D project MeGaPICS (Method towards Guarantee of Solar Cooling and Heating application – funded by the French National Research Agency). In fact, the PISTACHE tool was developed to provide professionals with a practical tool to design and to estimate the performances of different solar heating and cooling systems. After a short description of the PISTACHE tool, its validation is performed followed by a sensitivity analysis which is conducted using the method of Fourier Amplitude Sensitivity Test (FAST). The obtained results will be displayed and discussed at the end of this paper.
