Abstract
Dehumidification systems based on liquid desiccant have the potential to lower the latent cooling load of traditional vapour-compression airconditioning, especially in humid climates. This paper presents an experimental research on a liquid desiccant dehumidification system using calcium chloride that was run under controlled winter conditions. The effects of inlet air velocity and regeneration temperature on the outlet air relative humidity are evaluated. The results indicate that lower air velocities improve moisture removal because of increased air–desiccant contact time. The regeneration at about 58 C gave a relatively stable regeneration behaviour with a small range of outlet air relative humidity under the conditions of the experiment. The work gives experimentally determined operating trends applicable to real-world humidity-control applications and low-grade heat regeneration, and observes that the results are not to establish universal performance standards but to assist in optimising systems.
