Since apparatus is used frequently, equipments may break down easily. Often, we’ll need a great amount of budget for mending these damaged equipments. Therefore, we have come up with an idea in order to overcome the difficulties. AI (artificial intelligence) related technology has been under research for several years. Due to the fact that people demand computers to become more intelligent, there are many new innovations to be developed within the field of AI. Expert system is one of the newest technologies that increase the benefits brought to us through AI. Different from the conventional program, the expert system has plenty of advantages which include graphical interface, inferring mechanism, and knowledge-base, which can store a lot of professional knowledge. Moreover, the program is almost a real expert for it could teach people by its dialogue function. Based on this advantage, the unit can save an amount of money from using the expert system. Prolog is a program language used to write expert systems. It was invented by Colmerauer and Roussel in 1972. Because of its powerful function, Japan uses it as a tool to create the Fifth Computer Generation System (FGCS). According to the plan, the system must contain many user-friendly functions, which enables it to receive information by listening to people’s voice, and it can learn everything – almost as much as human beings. As for the programming of the VII language, Prolog uses a special syntax. When the predicate matches the fact, the function would be executed. This special program syntax is good for describing things. From now on, Prolog will be much more welcomed because it works in a more acceptable way for people. Finally, we would like to promote the techniques to the field of air-conditioning in order to offer people a new solution to deal with the flaws.
