Investigation of a Solar Polygeneration System for a Multi-Storey Residential Building-Dynamic Simulation and Performance Analysis

In the present study, performance of a novel configuration solar polygeneration system for multi-family residential building is investigated using dynamic simulation models. The consists in Building Integrated PhotoVoltaic/Thermal (BIPVT) collectors, water-to-water reversible heat pump and an adsorption chiller. will ensure space heating winter, cooling summer domestic hot water electricity all over year multi-storey located Algiers (Algeria). case insufficient energy, equipped with gas-fired heater auxiliary production, whereas supplied by national grid. First, models components were described developed TRNSYS environment. Then, energy-economic model based on calculation primary energy consumption, saving, simple payback period electrical thermal fractions, was carried-out. Finally, terms daily, monthly yearly results compared to conventional commonly used Algerian buildings. indicate that collectors have potential cover more than 56% 72% requirements, respectively. total saving achieved respect one 37.1 MWh/y, which represents 39% consumption system. However, economic feasibility proposed difficult be due high initial cost collectors. Indeed, obtained 55.40 years. Moreover, sensitivity analysis has been performed aiming at studying effect various technical economical parameters performance. shows energetic as well performances are strongly influenced photovoltaic/thermal filed area, unitary electricity. becomes economically profitable when 400 €/m² 0.12 €/kWh. Additionally, better climate conditions where requirements important.
