20.500.12556/DiRROS-16603 Experimental study of the fire dynamics in a semi-enclosure formed by photovoltaic (PV) installations on flat roof constructions Correction to: Experimental Study of the Fire Dynamics in a Semi-enclosure Formed by Photovoltaic (PV) Installations on Flat Roof Constructions Flame spread experiments upon a BROOF(t4) compliant flat roof mock-up located below a vertical barrier were carried out for variations in gap height, inclination, subjacent insulation material, and the barrier type (stainless-steel board or photovoltaic (PV) module). A binary flame spread scenario was identified, where re-radiation from the flame facilitated self-sustained flame spread if the gap height to the horizontal panel was below 10 cm for the stainless-steel board and 11 cm for PV modules. These were defined as the critical gap heights. Inclination of the PV modules increased the critical gap height and caused a 25% faster flame spread rate (FSR) than the FSR below horizontal modules with the same gap height at the location of ignition. The faster FSR for inclined modules caused a 40% reduction of the maximum temperature measured at a depth of 70 mm in the insulation materials (242°C). Based on temperatures measured in the insulation materials, the 60 mm polyisocyanurate (PIR) insulation performed slightly better than the 50 mm mineral wool insulation. However, it is expected that the mineral wool would outperform the PIR insulation if tested with the same thickness, as it insulates significantly better at high temperatures. Finally, no sustained flame spread was observed on the back side polymer sheet of the PV modules, but one of the three PV module brands produced burning droplets. Based on the experiments, it can be concluded that the current standards are inadequate as the introduction of a PV system on a compliant roof construction enables flame spread. photovoltaic (PV) installations flame spread fire dynamics property protection open access fotovoltaične inštalacije širjenje plamena požarna dinamika zaščita lastnine odprti dostop true false true Kluwer Angleški jezik Slovenski jezik © 2022 The Author(s) Neznano 2023-05-31 09:41:01 2023-05-31 10:06:01 2023-06-15 09:52:21 0000-00-00 00:00:00 2022 0 0 Opis vira z dne 1. 3. 2023 in 26. 4. 2023; Nasl. z nasl. zaslona; Correction to: Experimental study of the fire dynamics in a semi-enclosure formed by photovoltaic (PV) installations on flat roof constructions, Vol. 58, iss. 5, Sep. 2022, str. 3297–3316, DOI: 10.1007/s10694-022-01267-6, je objavljen popravek članka.; str. 2017–2054, 3297–3316 iss. 4 Vol. 58 Jul. 2022 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2022-06-02 62 1572-8099 10.1007/s10694-022-01267-6 143588355 https://link.springer.com/article/10.1007/s10694-022-01267-6 Correction 0 c342ca3d-ff75-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22478 https://link.springer.com/article/10.1007/s10694-022-01228-z 0 c2a7c465-ff75-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22477 RAZ_Kristensen_Jens_Steemann_2022.pdf RAZ_Kristensen_Jens_Steemann_2022.pdf 1 Correction DFA28A2349788EFD00960B5764A184BD 44f225b1eaa0e2fe06da24bb30da56aea1ce4c099f98e1a95069894d2d7c0324 27bc9826-ff79-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22479 RAZ_Kristensen_Jens_Steemann_2022.pdf RAZ_Kristensen_Jens_Steemann_2022.pdf 1 4F47AE51C2BCB85B774D503021AAE23C d77b77cdfdb55921743559c3dbb19f0d427bd7e3cb87a594f44776a3c77ecae9 365bdd1d-ff79-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22480 Zavod za gradbeništvo Slovenije 0 0 0
