Abstract :
Liquid desiccant cooling system is a new type of air-conditioning system capable of saving energy. The dehumidification process
dominates the performance of this system, while the thermal properties of the liquid desiccant play a key role in improving dehumidification
effect. However, there is little work about how to choose a proper liquid desiccant that has a better performance. To settle this
problem, a novel method is proposed to search an ideal liquid desiccant by applying the nonrandom two-liquid equation (NRTL equation).
This idea is further applied to mixed LiCl and CaCl2 solution to work out the right mixture ratio with a better dehumidification
effect under certain working conditions. Moreover, the related experiments were carried out. The results show that: compared to single
LiCl solution, the dehumidification effect could be raised by more than 20% with mixed LiCl and CaCl2 solution.
