Common Program for Structure Design of Fin-and-Tube Evaporator and Condenser

The advantage of computer-aided design of evaporator and condenser of room air conditioner, compared with general design, was analyzed. The problems in the general design, which includes too much input and output parameters and complicated calculation, were successfully solved by dividing the program into three modules:input module, output module and calculation module. A general computer-aided design program was compiled with VB. Also the reliability of the program was tested by an example.
