| Summary: | The liquid desiccant system is comprised of an absorber, a regenerator, a sensible heat exchanger, a solution heating coil, and a solution cooling coil. The high concentrated desiccant solution dehumidifies the process air as it enters the absorber. The desiccant solution becomes less concentrated as it leaves the absorber and is transferred to the regenerator to be heated to the regeneration temperature by the solution heating coil. Regenerating the liquid desiccant always requires a slightly high temperature to produce a high concentration desiccant solution for the absorption process. This project aimed to evaluate the liquid desiccant system air dehumidification by reducing the desiccant temperature before it enters the absorber. The operation was conducted using the liquid desiccant system without a plate-fin heat exchanger and the liquid desiccant system without a plate-fin heat exchanger, using weather dependence air temperatures and relative humidity, and different inlet air velocities. |
