摘　　要：为激发学生对制冷及工程热力学的兴趣,并启发引导其如何分析工程热物理现象,培养基础扎实、善于分析解决工程问题及创新的卓越工程师人才,实验教学中心对单级蒸汽压缩式制冷循环实验教学进行了改革探索。在指导学生完成基本制冷循环实验操作与计算的基础上,增加探究性实验环节。学生目睹了制冷系统中各参数的关联性变化以及结露、结霜等现象,加深了对蒸汽压缩式制冷循环的理解,提高了实验教学质量,丰富了制冷空调实验教学内容,获得了较好的教学效果。IN order to stimulate students interest in refl＇igeration and engineering thermodynamics, and to inspire and guidance them how to analyze the phenomena of engineering thermophysies, to cultivate talented engineers who have a solid foundation, and be good at solving engineering problems, and innovation, , the experimental teaching center has ean＇ied our reform and exploration on the experimental teaching of single stage of vapor compression refl＇igeration cycle. On the basis of guiding the students to complete the bas- ic refl＇igeration cycle experimental operation and calculation, the exploratory experimental link was increased. Students witnessed the changes in the eon＇elation of various parameters in the refl＇igeration system, as well as condensation, fl＇osting, etc. , which deepened the understanding of the vapor compression refl＇igeration cycle, improved the （tualily of experimental teaching, enriched the experimen- tal teaching content of the refl＇igeration and air conditioning, and obtained some better effects.
