Abstract

Energy and exergy analysis of solar devices has drawn the interest of researchers across the globe. Energy analysis is a criterion to assess the efficient usage of solar energy. Solar energy storage at its maximum is a big challenge. This challenge can be resolved with the help of a solar dryer storage unit, as it is compact and possesses high storage density. But the problem is minimizing the cost. A low-cost phase change material (PCM) solves this issue; sodium thiosulfate pentahydrate is a PCM of low cost with high latent heat of fusion and its melting point is within the desired temperature range. To determine the usefulness of stored energy using sodium thiosulfate pentahydrate as PCM, exergy analysis based on second law is required. In this paper, energy and exergy studies were done during charging and discharging periods of PCM with a heat input and different mass flow rates of heat transfer fluid.

Introduction

Reducing the moisture content of products such as grains is known as drying, and it is a better way for preserving products for future usage. Besides, dried foods have good nutritional value. Since natural drying in open sunlight causes many hygienic and economic problems, new methods of drying are experimented. Among the drying methods, solar drying is the most economical, followed by natural drying (Kabeel and Mohamed, 2016).
