Development of virtual simulation scientific experiment system for air-conditioning pipe network based on virtual reality technology

This paper takes virtual reality technology (VR) as the core, combines 3D digital modeling technology and Web3D technology, and aims to realize the innovative integration of virtual simulation technology with experimental or practical teaching in colleges and universities, and form a virtual simulation experiment system. This system focuses on the shortcomings of practical teaching courses of air conditioning system selection and duct design, and puts forward comprehensive application solutions. Under the environment of ASP.NET, the system is designed and developed in the form of Web application, Innovative online education and virtual simulation experiment teaching method are introduced into the teaching activities of air-conditioning pipe network, and many functional modules such as theoretical study, simulation experiment, summary report, interactive question and answer are used to meet the actual needs of students and teachers. While making up for the deficiency of practical teaching in the current teaching mode, the system can strengthen students' ability to integrate theory with practice and promote their all-round development into high-quality qualified talents. In addition, the full implementation and application of the system will also effectively promote the information reform of higher education, and also make a beneficial attempt for the discipline construction under the new engineering background.
