D6.2 Results from functional and quality acceptance tests

We took measurements on a MiniStor prototype without photovoltaic thermal panels for winter and summer operating modes. These measurements included assessing several thermal parameters, evaluating the heat storage capacity, and analysing the pressure conditions within the system for each mode. Efficiency values werecalculated from the measured data. To carry out our measurements, we have set up at EMI’s facilities a specially designed mechanical device to simulate different thermal input and output conditions through usage of hot water at different temperature levels instead of that produced by the panels, which depends on weather conditions. The deliverable describes the procedures and equipment used, and the results obtained from these measurements. Measurements were not continuous in some cases due to faults which are typical during the prototype stage. Results from the measurements will be used in WP3 and for the product audit program (PAP).
