A novel hybrid solar ejector cooling system with thermoelectric generators

Abstract

A self-powered solar ejector cooling system with thermoelectric generators is presented in this work. The proposed theoretical model was built based on mass, momentum, and energy balances, and then solved using the Engineering Equations Solver Software. The capability of integrating a thermoelectric generation system with a solar ejector cooling system to generate electricity was studied. Furthermore, the performance of the whole system proposed, including the ejector cooling system and the thermoelectric generation system, was investigated from the perspective of the first and second laws of thermodynamics. The coefficient of performance of the conventional system without integrating the thermoelectric modules was 0.3095. However, the use of a thermoelectric generation system for power production to cover the circulating pumps electrical load resulted in increasing the system coefficient of performance by 13.3%. The exergetic efficiency of the proposed SECS is found to be 12.5%.
