Abstract
The use of a small wind turbine for the power supply of a radiative passive cooling system for indoor cooling or pre-cooling, even in areas with rather poor wind potential, was investigated in the present study. The passive cooling system was a lightweight aluminium nocturnal radiator, painted with an appropriate white paint and was established on the roof of the Department of Environmental and Natural Resources Management in Agrinio, in western Greece. The metallic radiator was used for indoor space cooling or pre-cooling, by providing cooled air to a specific thermal zone of the building of the Department. The limited energy demands of the system as well as the lighting demands of that specific thermal zone of the building were satisfied by a small wind turbine, placed on the roof of the building. Furthermore, the financial benefits of the system were investigated by a cost analysis, which gave excellent results and demonstrated that, even in areas with rather poor wind potential, there is the possibility of using wind power for domestic use in applications concerning indoor air conditioning. Finally, a neural network approach was used for modelling the energy consumption of a residential building in the area of western Greece using various wind energy and other climatic parameters.
