Abstract: Refrigeration is a process of reducing the temperature of the desired space under atmospheric temperature. The present system focuses on the design and fabrication of a Stirling refrigeration system with a β-type configuration. The refrigerants carbon dioxide and helium are used and the efficient among them is determined. The objective of the work is to achieve rapid heat transfer from the system and to reach a temperature of below -10 degree Celsius, which is done by reversing the cycle of a stirling engine by providing mechanical energy. This system consists of displacer and piston which is linked to a rhombic drive mechanism which is operated by the motor. Regenerator placed inside the displacer will absorb the heat to give out the cooling effect. Stirling-engine coolers are used as cryocoolers, a very efficient cooling device, in superconductivity and electronic research. They are found to be useful in many space applications due to their long working life and reliability as cryocoolers. The cooling effect obtained by the system and the work done to operate the system is determined and the COP is determined for both the working substance.
