Experimental and numerical analysis of desiccant wheels activated at low temperatures

The results show that a decoupling of the outlet air temperature and humidity ratio can be obtained when the process airflow rate and air regeneration temperature are varied. This decoupling allows several MRC values for a constant SHR value, and vice versa, to be obtained, achieving ranges of 7 kg h−1 and 0.25, respectively. These results suggest that a control strategy for DW activated at low temperatures, would allow MRC and SHR to be controlled by setting the process airflow rate and air regeneration temperature.
