Design and construction of a zeolite thermal energy storage system and experimental investigation of effective different parameters on its performance Iman Amrollahi Biyouki Amrollahi iman @ Gmail com Date of Submission on August 12 2018 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Dr Alemrajabi Prof Email rajabi@cc iut ac irAbstractIn recent years due to population growth and technological advancement demand for energy has increased Withthe reduction and limitation of access to energy resources energy storage in the world is important today Amongthe energy storage methods thermal energy storage is more investigated Thermal energy storage systems can playan important role in reducing our demand for fossil fuels One of the things that can be effective in storing thermalenergy 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 systemwith zeolite X13 and the study and analysis of the impact of various parameters on its performance have beenaddressed 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 airflow rate to the reactor After making the device the experiments were carried out to examine and analyze theeffect 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 whichhas 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 increasesthe maximum durability of the heat power of zeolite during the hydration process and does not affect the maximumvalue of the generated sensible heat power of zeolite during the hydration process increasing the dehydrationtemperature 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 investigatedusing BET test It was concluded that charging temperature above 180 C significantly reduces porosity of thezeolite However for any type of zeolite with a specified value there is a dehydration time and temperature that issufficient for complete dehydration of zeolite In this study the dehydration time is 6 hours and the dehydrationtemperature is 120 C Increasing the air flow rate to the reactor reduces the difference in temperature of the inlet and outlet of the reactorduring 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 ofthe reactor is reduced by 5 C but the amount of the generated sensible heat power increased from 125 watts to 180watts Increasing the moisture content of the inlet air into the reactor increases the maximum amount of generatedsensible heat power by the zeolite but the durability of this maximum heat power reduces Increasing the relativehumidity of the inlet air from 60 70 to 80 84 the maximum amount of the generated sensible heat powerincreased from 120 watts to 180 watts but the stability time of this maximum heat power decreased by almost 100
