In this investigation, a mathematical model was developed to study the performance of cross-flow liquid desiccant air dehumidifier (LDAD). The results show that desiccant solution to air mass ratio has the greatest impact on performance of dehumidifier. Inlet air humidity ratio and temperature have significant influence on outlet air humidity ratio and temperature, respectively. The outlet air humidity ratio, outlet air temperature and outlet desiccant solution temperature are increased with inlet desiccant solution temperature increasing. The increase of solution fraction leads to a slight decrease in outlet humidity ratio and dehumidification rate, but a little increase in outlet air temperature. In addition, when the solution fraction is 48%, the outlet solution temperature reaches the maximum value. Numerical results are verified by experimental ones with a maximum deviation of 8.7% in the outlet air humidity ratio.
