This paper experimentally researches thermal performance of thermochemical reactor for the zeolite 13X-water. It aims to improve the poor thermal conductivity of the zeolite 13X, a novel thermochemical reactor design aligning with copper strips (case 2) or fins (case 3). For the cases of the thermochemical reactor with and without copper strips or fins, the influences of the relative humidity and flow rate of inlet air on outlet temperature and water temperature lift. Related results reveal that 1) copper strips reactor obviously achieves higher water temperature than copper fins or smooth tube; 2) copper fins increases the outlet reactor temperature than first two cases; 3) the whole energy efficiency of reactor gradually increases from 0.48-0.53-0.78 in the order of the case 1 to case 3. During the whole discharging process, it can conclude that the outlet temperature of copper strips reactor is approximately 10 ℃ higher than that of the copper strips or smooth tube, however, its water temperature lift is 4.34℃ lower than case 2 and 0.87 ℃ slightly higher than case 1.Moreover, copper fins reactor presents the highest energy efficiency of 0.78. A simiplified methodology is proposed for the analysis of the zeolite 13X-water working pairs discharging process through the identification the critical points as result of thermal performance of the reactor.
