To reduce the production cost and running energy consumption of a solution dehumidification system

experiments were conducted in this study on dehumidification equipment based on a mixed salt solution consisting of LiBr and CaCl2. The temperature and humidity of inlet and outlet air as well as the energy consumption of the dehumidification device were measured. The dehumidification capacity

refrigeration capacity

and dehumidification performance coefficient of the system were analyzed. Based on the initial investment and working performance of the mixed salt solution

a comprehensive performance and cost ratio of the solution was weighed by considering the life cycle cost of the solution dehumidification system. The results showed that the mixed LiBr and CaCl2 solution at a ratio of 3:1 can obtain a higher dehumidification efficiency and lower cost compared to other combination

and the total cost can be reduced by 14.5%.
