In this study, the heat recovery performance of a
plate heat exchanger, which provides air to air heat transfer was investigated.
For the experimental set-up, a waste heat recovery device was designed and a
heat exchanger was placed in it. Three different operating parameters were
selected as fresh and exhaust air inlet temperatures and airflow rates. Three
levels for each parameter were determined. The effects of changing parameters
on the thermal effectiveness were analyzed by the Taguchi method. L9(33)
orthogonal array was used in performing experiments. Results indicate that
higher effectiveness can be obtained at low fresh air inlet temperature, low
airflow rate, and high exhaust air inlet temperature. In this way, the optimum
process parameter combination was revealed. Then, ANOVA was applied in order to
detect the significance order of each parameter. The results show that the most
important parameter among the others is the airflow rate. Moreover, the confirmation
test was performed in order to obtain the optimum parameter combination. The
experimental and predicted values are compatible with each other. This
experimental study approves that the Taguchi method can be used in improving
the exchanger performance.
