recordUN_Validation
Parameters for an uncovered flat-plate PVT collector without rear cover or back-side insulation
A record of IDEAS.Fluid.PVTCollectors.Data.Generic.
Information
For comparison with the simplified steady-state thermal formulation, this validation record is adapted to use the thermal coefficients a1 and a2 reported under the EU Ecodesign Regulation CDR 812/2013, which are provided directly in the collector datasheet.
For this PVT collector, additional real-life measurement data is publicly available (Veynandt, 2023) and has been used in the validation of IDEAS.Fluid.PVTCollectors.PVTQuasiDynamicCollector, which can be found in the IDEAS.Fluid.PVTCollectors.Validation.PVT_UN package.
