Physics-Based Dynamic Modeling of Solar-Powered Off-Grid Cold Storage for Perishables Using Modelica: A Case Study – Xingalool, Somalia
This paper presents a dynamic, physics-based Modelica modelfor simulating solar-powered, off-grid cold storage systemsused to preserve perishables. A preliminary componentlibrary, developed using the Modelica Standard Library,supports modular modeling of PV-powered chillers, thermalloads, and latent thermal energy storage (LTES), whichmaintains cooling during non-solar hours. The library isapplied to a 200 m³ cold room in Xingalool, Somalia,designed to stay at 5 °C. A case study simulating 500 kg ofcrop loading at 8:00 and unloading at 17:00 demonstratesthe system’s dynamic behavior under realistic solar andambient conditions.** This paper is intended to be presented as a poster.
