With the rapid development of information technology, the application of augmented reality technology in the field of education has attracted more and more attention. As a technology-intensive industry, refrigeration and air-conditioning industry requires more and more professional skills of employees. Traditional skills training methods are often limited to theoretical learning and basic operation, lacking interactive experience of real scenes, which is difficult to meet the teaching needs of modern apprenticeship. This paper first outlines the basic concepts of augmented reality and modern apprenticeship, and then analyzes several advantages of AR technology in teaching, including improving students' learning motivation and creating immersive learning environment. The article also discusses the application mode of AR technology in refrigeration and air conditioning skills training in detail, such as 2. 5 + 0. 5 training mode and curriculum system design, in order to improve the training effect through these methods and meet the needs of the industry for highly skilled personnel. © 2025 IEEE.
