The Research On Design Decision Support For Refrigeration Air-conditioning

Using the latest information theory and technology to support the design of the refrigeration air-conditioning, so that designers who are liberated form trivial and repetitious work could fix their attentions on innovation in the design with higher efficiency and quality. This is the goal of all the people who do researches on refrigeration computer aided design. The thesis is to set up simulation and optimization based Refrigeration Air-conditioning Design Decision Support System (RADDSS), based on the refrigeration air-conditioning simulation and optimization technology and decision support system (DSS) theory, which are very pop in refrigeration and information area. RADDSS combines the tow theory with routine calculation of traditional design in order to offer air-conditioning design more support.For the original intention above, the paper does research on the origins of the tow theory, analyses the differences and relations between them, points the possibility and inevitability of the combination of them, and sets up the RADDSS on the base of them.The thesis begins from the analysis of the refrigeration air-conditioning design. It gives way to offer service for design, from which it defines system's main function and content and builds the system model. Knowledge base and model base are embodiment of the system ideas. Based on production rule, it builds air-conditioning design knowledge base and reasoning machine to support design by giving design experience in routine calculation. Adopting DSS model base technology, using refrigeration air-conditioning simulation and optimization models, it builds RADDSS simulation and optimization model base. Computer simulation and optimization can take place of experiments in traditional design, therefore design cost can be reduced and quality and efficiency will be improved.
