在考虑工质与热源间热阻损失的内可逆卡诺制冷机模型基础上，用一常数项表示热源间的热漏，用一常系数项表示循环中除热阻和热漏外的其余所有不可逆性（如摩擦、涡流、惯性效应等），提出了一类较为完善的不可逆卡诺制冷机模型，并对此不可逆制冷机模型进行优化分析，导出了其最佳制冷率与制冷系数间的优化关系和最大制冷系数及其相应的制冷率。由定义的一常数项和一常系数项可定性、定量地分析不可逆性对循环性能的影响，所得结果包含了有关文献的一些特例。最后，给出了详细的数值算例，说明本模型的有效性。
Based on the model of the endoreversible Carnot chiller with consideration of the thermal resistance loss between working fluid and heat source, a constant term is used to denote the heat leak between the heat sources and a constant coefficient term to represent the rest of the cycle except heat resistance and heat leak Irreversible (such as friction, eddy current, inertial effect, etc.), a more perfect irreversible Carnot chiller model is proposed, and the irreversible chiller model is optimized and analyzed. The optimal cooling rate and the refrigeration coefficient Optimize the relationship and the maximum cooling coefficient and its corresponding cooling rate. By defining a constant term and a constant coefficient term, the influence of irreversibility on cycle performance can be qualitatively and quantitatively analyzed. The results include some special cases about the literature. Finally, a numerical example is given to show the effectiveness of the model.
