This study aims to investigate the improvement of Stirling heat pump performance with hot and cold ends’ heat exchanger combinations. From the experimental data obtained, to analyze the influence of different hot and cold ends’ heat exchanger combinations on the Stirling heat pump. From the theoretical model, this study refers to the non-ideal adiabatic model. The coefficient of performance (COP) is analyzed by the thermodynamic model. The experimental value and the theoretical value are verified against each other. Operating conditions at 4 bar charged pressure and 500 rpm rotational speed, the highest performance of cold and hot ends’ heat exchanger combinations is Type 4, and the 〖COP〗_M can reach up to 2.39.
