Optimization of convective heat transfer model of cold storage with circular fins evaporator using Taguchi S/N ratio and ANOVA

In this work design of experiments have been used to optimize various control factors of a cold storage evaporator space inside the cold room, in other words the heat absorb from the inside of the cold room by evaporator will be maximize. Already we have study about evaporator with rectangular plate fin now we have use circular plate fin.Taguchi orthogonal array have been used as a design of experiments. Three control factors with three levels of each have been chosen for analysis. In the evaporator space the heat absorbs by the evaporator and fins totally a convective heat transfer process. The control factors are Area of the evaporator with circular fin(A), temperature difference of the evaporator space (dT), and relative humidity inside the cold room(RH). Different amount of heat gains in the cold room for different set of test runs have been taken as the output parameter. The objective of this work is to find out the optimum setting of the control factors or design parameters.so as the heat absorb in the cold room by the evaporator will be maximum. The Taguchi S/N ratio analysis have used as an optimization technique. Larger the better type S/N ratio have used for calculating the optimum level of control parameters, because it is a maximization problem. Analysis of variance (ANOVA) was also performed on the test results to find out the significant control factors. © 2016, AMSE Press. All rights reserved.
