Abstract

An air duct is an essential component for transferring to the air in the blowing or compressor system. In most of the industrial site, a diameter of pipe and supply pressure of the air duct designed by simplified equation. However, simplified equations not consider resistance of the air duct that temperature of outside air and surface roughness of an air duct. Recently several attempts on energy cost reducing process in compressor systems, an example, advanced performance of compressor or driving processing change of compressor. However design of pipeline net does not improve an air duct or pipe. In this study, this problems solve using a detailed model. Therefore, Using the simulation model, since the air duct specifications of parameter. In the investigation through simulations, the effects of numerous design parameters such as length of pipeline net, diameter of the pipe, supplied pressure and demand flow rate have been studied. From the simulation results, it was determined that the mean length of pipeline net, diameter of the pipe and supplied pressure. This parameter satisfied the conditions for demand flow rate. Therefore, this study make suggest a way of energy cost reducing.
