This study examined a heating system based on a double piston alpha type Stirling heat pump with linear actuators and a regenerative heat exchanger. In such a system, linear actuators control the Stirling cycle via compression and expansion, which is expected to increase the COP of the system. The energy transformations and transmission mechanisms describe the configuration and operating principles. The prototype’s design parameters were determined using SimCenter AMESIM, a 1D modeling software. The prototype’s performance is analyzed using sinusoidal/linear piston displacement and with or without a regenerator. Actions were taken to improve the system’s performance.

摘要

This study examined a heating system based on a double piston alpha type Stirling heat pump with linear actuators and a regenerative heat exchanger. In such a system, linear actuators control the Stirling cycle via compression and expansion, which is expected to increase the COP of the system. The energy transformations and transmission mechanisms describe the configuration and operating principles. The prototype’s design parameters were determined using SimCenter AMESIM, a 1D modeling software. The prototype’s performance is analyzed using sinusoidal/linear piston displacement and with or without a regenerator. Actions were taken to improve the system’s performance.
