Reform and Practice of Experimental Teaching on One-stage Vapor Compression Refrigeration Cycle

IN order to stimulate students interest in refrigeration and engineering thermodynamics,and to inspire and guidance them how to analyze the phenomena of engineering thermophysics,to cultivate talented engineers who have a solid foundation,and be good at solving engineering problems,and innovation,,the experimental teaching center has carried our reform and exploration on the experimental teaching of single stage of vapor compression refrigeration cycle.On the basis of guiding the students to complete the basic refrigeration cycle experimental operation and calculation,the exploratory experimental link was increased.Students witnessed the changes in the correlation of various parameters in the refrigeration system,as well as condensation,frosting,etc.,which deepened the understanding of the vapor compression refrigeration cycle,improved the quality of experimental teaching,enriched the experimental teaching content of the refrigeration and air conditioning,and obtained some better effects.
