Abstract

The aim of this study is to determine the importance of the operation
factors affecting the recovery performance in air-to-air heat recovery
application where heat exchanger is used. The Taguchi experimental design
method has been applied to show the effects of the factors and obtain the
optimum process parameter combination. Thermal effectiveness has been
determined as performance characteristic. Experiments have been carried out at
varying air flow rate, fresh and exhaust air inlet temperatures. Taguchi's L9(33)
standard orthogonal array has been chosen as an experimental plan. The
significance level of the control factors has been obtained by using analysis
of variance (ANOVA). F test has been
performed to determine whether the study is statistically significant. The results show that air flow rate is the most
significant factor among the three factors that influences the thermal
effectiveness. The results prove that Taguchi method is an easily applicable
optimization tool for heat recovery systems.
