Research on split type air-conditioner simulation software base on dynamic link library technology

Matlab/Simulink is widely used in science engineering and various industries because of its multi-function and outstanding computing ability, but the interface of the model developed by Simulink is not amiable enough, and it cannot run without Matlab program environment. C# is a kind of object oriented programming language with powerful visual control library. DLL (dynamic link library) technology is used in windows system to sharing function library and data resource. In this paper, a combination of the powerful analysis function from Matlab/Simulink and visual control library with C# is realized via DLL technology. Some split type air-conditioner models were established and converted into DLL documents, and then, software written in C# language call these documents in its procedure. The documents can run in a computer without Matlab software installed, and the result agrees with that with Simulink. The comparison results verifies the validity and correctly of this kind of simulation method.
