CAD Of Air-Cooled Condenser & Scene Simulation Of Capillary Tube

This paper mainly describes the methods of CAD and optimization design about small scale refrigerating appliances based on an AutoCAD seconddeveloping tool-VisualLISP. Here Domestic Air-conditioner is taken as anobject, and Main researching content is optimization design and drawing of air-cooled condenser, and the interface of the whole software system is friendly and can be used conveniently.The research method of scene simulation based on Visual C++6.0 graphicdeveloping tool-OpenGL is also presented in the paper. Focusing on thecapillary tube of domestic air-conditioner, it can vividly show the inner fluid of the refrigerant in capillary tube.
