In recent years, due to population growth and technological advancement, demand for energy has increased. With the reduction and limitation of access to energy resources, energy storage in the world is important today. Among the energy storage methods, thermal energy storage is more investigated. Thermal energy storage systems can play an important role in reducing our demand for fossil fuels. One of the things that can be effective in storing thermal energy is the use of thermal energy storage property of zeolite materials. In this project, the design and construction of a laboratory prototype of a zeolite thermal energy storage system with zeolite X13, and the study and analysis of the impact of various parameters on its performance have been addressed. In the construction of this device, a rechargeable zeolite storage reactor was used, a blower, a humidifier, and three thermocouples were used to measure the temperature, and a speedometer was used to measure the air flow rate to the reactor. After making the device, the experiments were carried out to examine and analyze the effect of various parameters on the performance of the system. The parameters studied include dehydration time, dehydration temperature, inlet air flow rate, inlet air moisture content, the effect of uniform velocity of air, which has not been considered in other studies and the repeatability of a specific zeolite sample performance. Using these experiments and analyzes, it can be concluded in short that increasing the dehydration time increases the maximum durability of the heat power of zeolite during the hydration process and does not affect the maximum value of the generated sensible heat power of zeolite during the hydration process, increasing the dehydration temperature to 180 °C for zeolite does not affect the maximum amount of generated sensible heat power by zeolite. In addition, the effect of dehydration temperature above 180 °C on the porous zeolite structure was investigated using BET test. It was concluded that charging temperature above 180 °C significantly reduces porosity of the zeolite. However, for any type of zeolite with a specified value, there is a dehydration time and temperature that is sufficient for complete dehydration of zeolite. In this study, the dehydration time is 6 hours and the dehydration temperature is 120 °C. Increasing the air flow rate to the reactor reduces the difference in temperature of the inlet and outlet of the reactor during the hydration process, but significantly increases the maximum amount of generated sensible thermal power, In this study, by doubling the flow rate of the inlet air, the difference between the inlet and outlet temperature of the reactor is reduced by 5°C, but the amount of the generated sensible heat power increased from 125 watts to 180 watts. Increasing the moisture content of the inlet air into the reactor increases the maximum amount of generated sensible heat power by the zeolite, but the durability of this maximum heat power reduces, Increasing the relative humidity of the inlet air from 60 – 70% to 80 – 84%, the maximum amount of the generated sensible heat power increased from 120 watts to 180 watts, but the stability time of this maximum heat power decreased by almost 100 minutes. The uniform airflow profile of the inlet air into the reactor during the hydration process increases the total generated heat power of zeolite during the hydration process. At the end, a certain amount of zeolite was placed three times under the hydration and dehydration process, and the result was that three times the hydration and dehydration process had no effect on the maximum generated sensible thermal energy and the total generated sensible thermal power.
