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.
