A Study on Design Parameters of Stirling Engines for Buildings

One of the most promising projects in the application of combined heat and power(CHP) lies in energy production for buildings. Stirling engines are very applicable to residential buildings, especially because of the higher electricity/heat efficiency. A literature review on stirling engines is first provided and a number of research works on the development and applications of Stirling engines are discussed. Then according to buildings' energy consumption, relevant output of power density of Stirling engines is estimated. From the results, the design parameters of Stirling engines are derived and the temperature difference on frequency and performance of Stirling engines is also discussed
