Résumé

Dehumidification is crucial for human health and comfort. Therefore, we focused on using a liquid desiccant air-conditioning system as an alternative to the vapor-compression system. The required power mainly originates from the heat energy used to regenerate the liquid desiccant solution. Consequently, the system can utilize solar or waste heat, thereby saving energy. In this study, the solution flow rate that achieved the highest COP under the condition of a specific dehumidification rate was investigated by mathematical simulation. The variation in the solution flow rate not only influences the amount of solution in contact with air but also influences the temperature and concentration. Because this complexity influences the dehumidification and regeneration rates, a detailed investigation is required. As a result, the coefficient of performance of the system was maximized at higher flow rates of the weak and strong solutions and lower flow rates of the exchange solution.
