Numerical heat transfer modeling and climate adaptation analysis of vacuum-photovoltaic glazing

Vacuum-photovoltaic (VPV) glazing has attracted much attention due to its excellent thermal insulation performance and ability utilize solar energy. However, few simulation models have been established based on actual products rarely validated by experiments. In this paper, a four-layer CdTe-based VPV was developed the corresponding numerical heat transfer model with integration of dynamic power generation model. The then against both results from WINDOW program guarded hot box experiment. Afterward, employed analyze energy in diverse climate zones China Harbin, Beijing, Changsha, Guangzhou, Kunming used as representative cities. indicate that U-value proposed is 0.89 W/(m2⋅K), which good agreement experimental results. Compared normal double glazing, average reductions achieved air conditioning seasons are 128 kWh/m2, 23 45 52 kWh/m2 respectively. addition, annual outputs 47 48 34 36 study can be for energy-saving potential analysis optimization different meteorological conditions, could provide guidance effective application glazing.
