Simulation of a solar-assisted adsorptive system for freezing and cold storage.

Author(s) : POLONARA F., SANTORI G., FRENI A., et al.

Summary

In this paper, the simulation results of an adsorptive system driven by solar energy, to be used for freezing and cold storage, are presented. The system, consisting of an active carbon reactor connected to a solar collector and to an evaporator/cold box, is able to produce and store 5 kg of ice/day, in a north Mediterranean climate. The simulations were carried out by a dynamic mathematical model which uses real climatic data and is based on energy balances for the different components of the system. A parametric analysis, based on a full factorial design - a known statistical method that is used to evaluate the effects and interactions of different independent variables on a dependent variable was realized. The results obtained evidenced that the most influencing parameters on the system performance, are the transmittance/absorptivity coefficient of the solar collector and the heat transfer coefficient between the solar collector and the adsorbent material.
