Abstract:

In this paper we have done a theoretical experimentation on expansion process of a cold storage, which operates on vapour compression refrigeration system and then obtained results are compared using S/N Ratio and ANOVA analysis. We have chosen three control parameters as Inlet Temperature of expansion process (T1), Outlet Temperature of expansion Process (T2) and Pressure ratio (Pr) of expansion process for the theoretical experiment and change in entropy (ΔS) is taken as the response variable of the experiment. Main objective of this study is to show how change in entropy (ΔS) in expansion process in a refrigeration system of a cold storage by several control parameters.

Keywords:

ANOVA, Change in Entropy (ΔS), Cold Storage, S/N Ratio
