• Heat transfer within onions is dependent on its operating conditions. When the relative humidity increases, onions stored in cold storage start sprouting and rotting. It is important to reduce the relative humidity under the recommended value of 55–65%. The recommended temperature for a cold storage system is below 5 °C. Keeping onions fresh for an extended amount of time required lowering relative humidity and temperature to the optimal level. This study is based on both experimental and computational fluid dynamics software (Ansys Fluent 19). For maintaining relative humidity inside the cold storage, the desiccant cooling system is used. The duct has been added to the cold storage, and desiccant material named blue silica gel is placed into the duct. Desiccant dehumidifies the air. In addition, a fan has been placed on the duct for proper circulation of air through it. The final obtained temperature was 4.6 °C, and relative humidity was recorded as 58.5%. The results obtained have been validated with the experimental results. Based on this, it can be stated that while storing onion into the cold storage system, desiccant material is very effective and keeps the onion fresh for a longer period.
