| Abstract: | Thermochemical energy storage (TCES) systems are an effective solution for long-term energy storage, offering high energy density and minimal energy losses, particularly for space heating applications. However, the practical application of inorganic salt hydrates as thermochemical materials is limited by cycling instability, agglomeration, and deliquescence during charging and discharging processes. Porous matrices, such as molecular sieve-3A, provide a promising alternative to overcome these challenges. This study evaluates the adsorption behavior of molecular sieve-3A in an open TCES system under varying charging temperatures. Experimental investigations are conducted in a rectangular reactor at an airflow velocity of 1.4 m/s and controlled inlet conditions, considering five different charging temperatures (80 °C, 90 °C, 100 °C, 110 °C, and 120 °C). Results reveal that molecular sieve-3A achieves optimal performance at a charging temperature of 120 °C, with a ~13 °C rise in the outlet air temperature and a maximum discharging efficiency of 22.86%. These findings demonstrate the potential for deploying molecular sieve-3A toward efficient energy storage in open TCES systems to ensure thermal comfort within living spaces. |
