Liquid desiccant

The main focus of this research is to estimate the ability of a liquid desiccant (LD) system operation to remove microorganism particles. The dehumidification performance of the LD systems generated by using a lithium chloride (LiCl) solution as the liquid desiccant material. To verify the removal performance of microorganism particles, the experimental method was divided into cases where the process air passed or bypassed the LD unit.

A liquid desiccant fresh air processor is presented whose driven force is low-grade heat (65~70℃ hot water). Inside the processor, the desired cooling source for air’s dehumidification is indoor exhaust air’s evaporative cooling energy. Multi-stage structure is used to get higher total heat recovery efficiency of indoor exhaust air. The mathematical model of the fresh air processor is set up and realized by SIMULINK procedure. As the practical liquid desiccant fresh air processor is developed, its performance is tested with average COP (cooling load divided by heat source) 1.3.
