The finite-time (exergy) analysis method is used to study the influence of thermal resistance and heat loss on the optimization of exergoal economy of a ferroelectric Stirling refrigerator. Utilizing the thermodynamic properties of ferroelectric crystals, considering the heat transfer law obeys Newton’s law, the basic optimization relationship of ferroelectric Stirling refrigerator is obtained. Taking the profit margin as the target, the refrigeration coefficient and other performance parameters are derived when the maximum profit margin is obtained. The conclusion can provide guidance for the research and design of the ferroelectric Stirling refrigerator.
