This paper aims to search for a more economical multi-component solution to replace single solution and validate its dehumidification and regeneration performance. A configuration scheme for multi-component solution is forecasted by simple mixing rule. Moisture content of outlet air is used as evaluation indexes. Experiments are carried out to verify the dehumidification capacity and regeneration capacity between single solution and multi-component solutions. 43%

45% and 48% LiCl/CaCl2 multi-component solutions are substitutions for 39% LiCl solution. 51% LiBr/CaCl2 multi-component solution is substitution for 52% LiBr solution. Taking dehumidification performance

regeneration performance and economy into consideration

48% LiCl/CaCl2 multi-component solution has 29.5% higher regeneration capacity than 39% LiCl solution and one third price of 39% LiCl solution. Since it has the best regeneration capacity

lowest price and slightly worse dehumidification capacity

it is the best substitute for dehumidifier. 51% LiBr/CaCl2 multi-component solution has 50.8% higher regeneration capacity than 52% LiBr solution. It also has similar dehumidification capacity to 52% LiBr solution and half price of 52% LiBr solution. It's a good substitute for dehumidifier.
