Performance of Unglazed Photovoltaic-Thermal Collectors for Cooling Purpose
Popis výsledku v původním jazyce
Unglazed photovoltaic-thermal (PVT) collectors for combined usable heat and electricity production are still expanding on the market. Besides the summer heat production and whole year electricity production the unglazed PVT collectors can be used also for night cooling (sky radiation and wind convection heat exchange). Different unglazed PVT collectors have been experimentally tested for verification of reliable model for night cooling operation. Based on the results, the model has been implemented into simulation software TRNSYS. Simulation analyses of the cooling performance for different climate and operation conditions have been performed. While best of tested unglazed PVT collectors can achieve average specific cooling power around 110 W/m2 (80 kWh/m2.season) at chilled water temperature 20 °C in the climate conditions of central and northern Europe, in the climate conditions of south Europe these unglazed PVT collectors achieve not more than 38 W/m2 (27 kWh/m2.season) during summer season (June–August).
