چکیده انگلیسی
In this study five different sorbents were tested in a novel prototype system. Four sorbents were salt based composites (SIM's) and one was Zeolite 13X. According to the results, the coefficient of performance (COP) of the system varied in the range of 1-2 for short-term operation (where tâ¯<â¯240â¯min) depending on the sorption material properties and system operating conditions. The overall performance of the prototype sorption storage heater was determined through long cycle testing. The system provided â 6.8â¯kWh thermal energy output with a sorbent volume, Vsâ¯=â¯0.04â¯m3 (over a 1200â¯min discharge time), corresponding to an energy density, Edâ¯=â¯170â¯kWh/m3. The required charging duration, to desorb the moisture was experimentally determined as 360â¯min. Based on the total energy input-output for both charging and discharging processes, the COPS was calculated at 2.39. According to the analysis, the experimental results were found in good agreement with the numerical simulation.
