Résumé

In this paper, a new kind of dehumidification system which consists of a dehumidifier, a generator, two heat exchangers and a mechanical vapour compressible heat pump was studied. When this system was operating, the desiccant solution was evenly distributed over the evaporator by many spray heads. The cool from evaporator was used to cool the absorption processes and simultaneously cool the air at desired condition to the space. The heat from condenser was used to heat the diluted desiccant solution for regenerating. Both will enhance the dehumidification capacity. According to the experimental results and a simplified model, the performance of the dehumidifier was discussed under the effects of variables such as flow rate, temperature, concentration of desiccant solution, temperature and humidity of air, the effectiveness of heat exchanger and cooling capacity. The results show that good system performance and energy saving could be achieved if proper values of these variables are selected.
