다국어 초록 (Multilingual Abstract)

This paper presents the development of automation procedure for the selection of axial-flow fan satisfying given requirements. Due to the variety of customers' requirements, most of axial-flow fan manufacturers produce fans of a wide range of dimensions and corresponding performance test results which often build up to a great amount, in general as the form of documents and tables. Whenever a requirement is given, manufacturers have to examine all the test results repeatedly to select the most appropriate dimension of the fan to produce and deliver. Even with small amount of the data, the procedure of fan selection is very tedious and troublesome, even erroneous. Hence, the automation of the fan selection procedure is of importance to increase the efficiency both in production and business. This paper describes the algorithm of automatic fan selection procedure and development of user-friendly programs. All the test data are formulated into several standard equations in least square sense, and accumulated in a database using Microsoft Access. Once a customer's requirement is placed, the program seeks for appropriate fans using SQL and proposes several fan dimensions to user both in tabulated and graphic form. With the developed automatic selection system for standard axial-flow fan, it is expected that work efficiency is increased, cost is reduced and technical sales is highly efficient.
