Optimization of Heat Gain by Air Exchange through the Cold Storage Window

Abstract

Energy is the one which is playing a vital role in today’s lives. In cold storage, if most of the heat is captivated by the evaporator inside the cold room due to convection, condensation and due to air exchange through the windows, more quantity of energy will be needed to maintain the desired temperature range inside the evaporator space. In this paper, author tried to optimize the heat gain by the air exchange through the windows of cold storage in the evaporator space using the Taguchi S-N ratio analysis. Temperature difference, Height of cold store window and Relative Humidity are the primary variables taken for optimization of heat transfer and for each parameter three ranges are chosen for the model development. Graphical elucidations justify the model proposed with the Taguchi S-N ratio analysis. The study shows that the model is good for cold storage application saving the heat energy.
