Now we make theoretical analysis to cost reduction of corrugated pipe in present R410A refrigerant sys-tem and put forward a size of material feeding with light pipe to realize cost reduction according to R410A refrigerant physical properties as well as pressure formula to biggest test of corrugated pipe.

This paper describes the design of air conditioning complex curved surface sheet metal parts and analysis method, from the perspectives of design method, simulation analysis, parts measurement comparison, etc; in order to meet the requirements for structure and usage, stiffness and strength, and economy.

According to the vector tube bending principle of the CNC pipe bender,use Pro/ENGINEER pipe feature for 3D modeling of air conditioner pipeline and 2D projection conversion,In combination with the CNC pipe bender program features,propose a reasonable way of bend dimensioning in order to facilitate Programming for the production process and parts inspection,reduce the number of test bends,to achieve productivity gains and production costs of the air-conditioner pipe fittings.
