摘要
在考虑制冷剂与热源间热阻损失的内可逆卡诺制冷机模型基础上，用一常数项表示热漏损失，用一常系数项表示循环中除热阻和热漏外的其余不可逆性（如摩擦、涡流、非平衡等），提出了一个新的不可逆制冷机模型。导出了其最佳制冷率、制冷系数关系和最大制冷系数及其相应的制冷率。
On the hasis of the reversible Carnot refrigerator model considering the losses of heat resistance between refrigerant and heat reservoirs,this article presents a new irreversible Carnot refrigerator model by taking account of the losses of heat leak and the other irreversibilities,such as friction,turblence,nonequiblium and so on,together with heat resistance by using a constant parameter and a constant coefficient.The relation between cooling load and COP(coefficient of performance) and the maximum COP and the corresponding ccoling Ioad are derived.
