THERMODYNAMICS AND DESIGN PRINCIPLES OF REFRIGERATION SYSTEMS

摘要

This paper has presented an attempt of overview of the principles involved in refrigeration theory throughout two hundred year development during one-hour lecture. The author has benefited from his experience with undergraduate teaching for mechanical engineering students in writing this paper. It is noteworthy that because of lack of time, many details are beyond the scope of the current presentation, as modern refrigeration is a powerful engineering field with a wide range of methods and a variety of equipment and designs. On the other hand, novel but well-developed tools of thermodynamic optimisation using exergoeconomics and ecological costing could considerably improve application of the first and second law analysis for the refrigeration system design. It is important to mention that the successful accomplishment of a refrigeration system design is a complex assignment, requiring principles not only from engineering thermodynamics, but also from fluid mechanics, heat and mass transfer, mechanical design, automatic controls, etc.
