Abstract

A portable thermal energy storage (TES) system that can melt ice to generate water has been developed and tested. The core of the experiment was a PCM-filled TES container, with an Icebox placed inside. Stearic acid was used as the PCM, and its melting and solidification characteristics matched those of other research. Five trials were conducted to assess the effectiveness of the system. Each trial lasted 22, 88, 104, 188, and 78 minutes, with trials 1 and 2 having a high heat transmission rate. Trial 5 was terminated due to a lack of heat. The PCM required 408.34 KJ/kg of heat to melt, and it absorbed a total of 1226 KJ of heat. For each trial, 230 KJ of heat were needed to heat the water from -60°C to 250°C, and 450 KJ of heat were needed to heat one kilogram. The PCM had a charging efficiency of 34.05%, a discharging efficiency of 95.61%, and a total system efficiency of 32.56%. Modifying the charging procedure could increase the system’s overall efficiency.
