The Stirling cycle is one of the thermodynamic cycles that has many advantages.
Advantages of this cycle have made Stirling engines popular and widely applicable to the industry and other applications. One of the advantages of the
Stirling cycle is its ability to operate inversely to produce cold energy. In this paper, a novel structure is proposed by which cold energy can be produced by a heat source using the coupling of two similar Stirling engines. By using this system, cold energy can be produced directly by the heat generated from renewable or non-renewable sources. The system is able to produce cold energy at different temperatures using solar energy, heat dissipation in thermal systems, biomass fuel, or other heat sources. Thermal energy is directly converted to the required mechanical energy for refrigeration in this system, which is the reason why this system is more efficient than others that convert mechanical energy to electrical energy and, then, convert the electrical energy to cold energy. In this paper, in addition to introducing and analyzing the proposed system, simulations are performed, showing that a temperature of
