Teaching methods of optimal design of building cold and heat source systems assisted by virtual reality technology

Presents a virtual reality software platform, in which the whole design process is divided into several phases. Students can learn how to select different design parameters in different phases, and carry out investment analysis and operation cost analysis of different schemes. Finally, they can simulate the whole system according to the design scheme, and obtain the optimal design scheme under different climatic conditions or operating conditions. This platform is a teaching link of professional course “refrigeration technology”, using virtual reality technology to connect the relevant knowledge points of several courses, and it can show students how to use these knowledge to solve problems of optimal design and operation regulation of cold and heat source system, which is helpful to graduation design.
