Thermal profile of a thermal energy storage system

Abstract

The thermal performance of a thermal energy storage (TES) system suitable for solar thermal applications has been tested and analysed. The experimental set-up consisted of a TES tank, thermo couples,pico data logger , thermia B oil was used as both the heat storage material and heat transfer fluid. The TES tank was built using mild steel material of dimensions (internal diameter of 10cm and height of 40cm) thermocouples (temperature sensors) were arranged inside the tank to measure the temperature profile during charging a 1.5KW heater was purchased and used and refined thamia B cooked and its temperature studied Data logger interface with the computer were connected to the temperature sensors the data logger configured to measure temperature in every one minute the experiment had to run for one hour until the maximum temperature in the tank is 220 0C ,The heat transfer was such that hot oil flowed inside the TES tank as the upper tank being too hot and the lower tank being too cold, which was in contact with the oil
