Performance optimisation for endoreversible Carnot refrigerator with complex heat transfer law

The relationship between cooling load and coefficient of performance (COP) of an endoreversible Carnot refrigerator is derived based on a new generalised heat transfer law, including generalised convective heat transfer law and generalised radiative heat transfer law, q proportional to(Delta T-n)(m). The results obtained include those obtained in many publications and can provide some theoretical guidance for the design of real refrigerators.
