Energy Performance of a Cogenerative Photovoltaic System for the Production of Electrical Energy and the Air Conditioning of an Open Space Building
Abstract
The energy performance of a co-generative system, represented by hybrid solar capture field with PV-T parabolic concentration having a degree of freedom, was determined. Thermal energy is provided to the building by means of the radiant ceiling distribution system, which is not an integrated part of the structure. The refrigerant flow rate is stored in a hot tank which is used directly in winter to supply the radiant ceiling, or by means of a water-water heat pump. In summer, stored thermal energy is instead used by a simple effect absorption chiller. The produced electrical energy is entirely self-consumed. The dynamic simulation of the building-plant system was carried out with the TRNSYS simulation code which allowed for the determining of the main performance indices by varying some parameters, referring to climatic data for a location in southern Italy.
