ABSTRACT

This paper takes the air-cooled vertical refrigerated display cabinet as the research object, analyzes and improves the noise problem of the vertical refrigerated display cabinet by using TRIZ theory. Firstly, the noise problem of vertical refrigerated display cabinet is clearly defined and the main noise sources are determined;secondly, the product noise problem is transformed into TRIZ problem model, and the problem model is determined to be a technical contradiction; secondly, the idealization level of each component is analyzed to determine the useful and harmful functions; finally, the invention is determined by using archishure general engineering parameters and contradiction matrix Principle and find a specific solution, effectively reduce the noise of vertical refrigerated display cabinet.
