Life cycle cost analysis (LCCA) of Stirling-cycle-based heat pumps vs. conventional boilers

open access: yesCleaner Environmental Systems, 2023
Heat pumps (HPs) which use low temperature (waste) heat and renewable energy sources to provide high temperature heat are widely regarded as a critical technology for reducing carbon dioxide emissions in the industrial sector.

Analytical Solution of Heat Transfer Performance of Grid Regenerator in Inverse Stirling Cycle

open access: yesEnergies, 2022
The regenerator plays an extremely important role in the Stirling circulation. A grid regenerator can be used for inverse Stirling machines at room temperature due to its low flow resistance.

Thermoeconomic analysis of an irreversible Stirling heat pump cycle [PDF]

open access: greenThe European Physical Journal B - Condensed Matter and Complex Systems, 2006
In this paper an analysis of the Stirling cycle in thermoeconomic terms is developed using the entropy generation. In the thermoeconomic optimization of an irreversible Stirling heat pump cycle the F function has been introduced to evaluate the optimum for the higher and lower sources temperature ratio in the cycle: this ratio represents the value ...
