在授课中,对于制冷空调部件、制冷(热)过程、系统流程的讲解一直是个难点,传统方法一般采取板书与挂图相结合的方式讲解,对于动态过程通过板书和挂图是无法讲解的。虚拟模型库的开发是根据制冷专业的教学需要开发的一项课题,它极大地提高了学生对元部件的感性认识,提高了学生对系统流程、动态过程的认识,增强了教学效果,为理论与实践的学习提供了依据。
In teaching, for the refrigeration and air conditioning components, refrigeration (heat) process, system flow to explain has been a difficult task, the traditional method generally take the form of a combination of blackboard and flip chart to explain the dynamic process through the blackboard and flip chart is unable to explain. The development of the virtual model library is a subject developed according to the teaching needs of the refrigeration specialty. It greatly improves students ’perceptual understanding of the components and enhances the students’ understanding of system processes and dynamic processes, and enhances the teaching effect. And practice provides the basis for learning.
