摘要

The theory of finite time thermodynamics is applied to analyze the performance of irreversible air refrigeration cycles in this paper. For the fixed total heat exchanger inventory,the ratio of heat conductance of low-temperature side heat exchanger to that of high-temperature side heat exchanger is optimized for maximizing the cooling load and the coefficient of performance (COP) of the cycles. The influences of various parameters on the characteristic of the cycle are analyzed. The results obtained may provide guidance for the design of practice air refrigeration plants.
