Expert System Of Small Built-up Refrigeratory Design

The research on application of expert system based on rules in refrigerating and air-conditioning field is studied in this thesis. With a example of small built-up refrigeratory design,through the experiential design method,quantities of symbol reasoning and experiential-data which will be met in small built-up refrigeratory design have been analyzed in detail. As a result,based on the model of small built-up refrigeratory design established with expert system technique,the programme of small built-up refrigeratory design have been worked out by using CLIPS,a kind of expert system programming tool. In this programme,the database of many stored foods and experiential database are described by using production system,and,inexact reasoning is settled down with the method of fuzzy logic,finally,by separating the control knowledge and field knowledge,the design clue of expert in field is incarnated in the form of rules-base .The expert system created can simulate the thought and decision-making of expert in HVAC field,and get the anticipative results.
