THERMODYNAMIC ANALYSIS OF THE SOLAR POND LAYERS FOR SUSTAINABILITY APPROACH

40690

In this paper, a comprehensive thermodynamic modeling for determining the sustainability approach is given of the solar pond layers for thermal energy storage. The solar pond layers consist of three zones as an upper convective zone (UCZ), a non-convective zone (NCZ) and a lower convective zone (LCZ) or heat storage zone (HSZ). The energy, exergy, energy efficiency and exergy efficiency of the three layers of the solar pond are examined under the variation of the global solar radiation and ambient temperature. Also, the parametric studies show that the global solar radiation and ambient temperature significantly affect the thermodynamic parameters. The exergy results given that the LCZ has the maximum exergy of the solar pond layers, due to the heat energy store in this layer and high temperature difference between the LCZ and ambient temperature. The maximum exergy efficiency for the UCZ, NCZ and LCZ layers are obtained to be 38.1 %, 39.84 % and 40.08 %, respectively.
