Performance Analysis of Refrigerated Storage Chamber Using Phase Change Material

Abstract

The research work aims to analyze the refrigerated storage chamber using phase change materials to solve the
problem related to improper storage and handling of vaccines, blood samples and organs. This analysis focuses
mainly on design and fabrication of an environment friendly refrigerated storage chamber which can be used in
areas where electricity supply is erratic and to fabricate a model to maintain optimum temperature for vaccine
storage, blood sample and organ storage using a phase changing material. PCMs behaves isothermally in nature, and
thus gives higher density energy storage and the ability to operate in a range of temperature conditions. Three
phase change materials namely acetic acid, sodium sulphate decahydrate and glycerol are used for the experimentation
purpose. These phase change materials are used in frozen form. The results obtained from experimentation are
verified using Ansys software. Results shows that the PCM Sodium Sulphate Decahydrate [H20Na2O14S] maintains
lowest temperature in range of 1.5 – 8 degree for 350 minutes and extract maximum heat. Similarly, for server unit
the temperature ranges to be maintained is 10 to 22 degree which is maintained for 1500 minute.
