摘要：
A liquid desiccant dehumidification system driven by low temperature waste heat was simplified to 4 main subsystems (dehumidifier, regenerator, flue gas-solution heat exchanger, cooling water-solution heat exchanger) which were analyzed based on the energy analysis method of the second law of thermodynamics. The impacts of different regeneration temperatures to the energy efficiency of each subsystem were compared, showing that the energy efficiency of dehumidifier and water-solution heat exchanger were reduced by increasing the regeneration temperatures. Further analysis showed the improvement potential of energy efficiency in the system came from the two heat exchangers, hinting the direction of system's improvement. By comparing the impacts of regeneration temperature on the energy efficiency of the system and dehumidification performance, it is shown that the dehumidification performance was improved with sacrificed the energy efficiency of the system through increasing the regeneration temperature.
