Adsorption dehumidification is gained extensive consideration as an alternative for air conditioning devices. Choosing the appropriate parameters is necessary to improve the performance of the system. In this study, we performed the impact of desorption air temperature on the desiccant ability and thermal performance of desiccant dehumidification (DSCDH) system. The test section was a honeycomb desiccant block made of polymer. Low desorption air temperatures of 35ºC, 45ºC, 55ºC and 65ºC were experimentally investigated under a maintained adsorption air temperature of 20ºC. The mass flow rates of the air and time ratio for desorption and adsorption were remained constant in the value of 0.1 kg/s at 60 minutes for desorption and 120 minutes adsorption. As the results, we found that the thermal performance decreased with the rise of desorption air temperature. In contrary, the dehumidification ability was enhanced with the increased of desorption air temperature. In conclusion, the high desorption air temperature gives insignificant effect on the system performance. On the other hand, it is noteworthy on the dehumidification ability of the system. The thermal performance of the system was found in the values of 0.62, 0.44, 0.35 and 0.29 for desorption temperatures of 35ºC, 45ºC, 55ºC and 65ºC, respectively.
