## 4 Conclusions  
The effect of the latent heat on the performance of the desiccant dehumidification system in terms of latent heat effectiveness and latent heat ratio through five different desorption temperatures of 308, 318, 328, 338, and 345 K were experimentally examined. It was revealed that the highest latent effectiveness and dehumidification ability were found at the highest desorption temperature of 345 K, at 0.91 and 6.8 g/kg, respectively. The maximum latent heat ratio was obtained when the system was driven by the low desorption temperature of 308 K. We clarified that even though the system was driven by a low desorption temperature, it could nonetheless give a good moisture removal performance with a high latent heat ratio. An effective dehumidification system is intended for giving a high latent amount of heat, which shows that the system has high dehumidification capacity. Moreover, it also implies that the higher the ratio between the latent heat and sensible heat, the greater the effectiveness of the desiccant dehumidification system.
