CAD Of Parts Of Small Refrigerating Plants & Simulation Of Practice

This paper mainly describes how to exploit CAD system of the parts of Small RefrigeratingPlants based on an AutoCAD second developing tool------VisualLisp. It implements not only theparametric design and drawing of many kinds of condenser to the users' requirements, e. x. the bushing condenser, the horizontal shell-tub condenser and the snake-tube condenser. The interface of the whole system is friendly and can be used conveniently.Furthermore, the paper introduces the developing method and the main functions of the simulation system for practice of small refrigerating machine, which is based on Web.
