Abstract: In liquid desiccant-operated evaporative cooling systems (LDECS), the latent heat load of air-conditioning in the confined space is adsorbed by the liquid desiccant, according to the adsorption capacity. Whereas sensible heat load that controls the temperature is handled by the evaporative cooling system. The key difference between conventional vapour compression refrigeration system (VCRS) and LDECS is that latent and sensible heat load of air-conditioning in the confined space are handled separately by different sub-components in LDECS whereas handled by the single cooling coil in VCRS. In review, various components of LDECS such as dehumidifier and regenerator, desiccant heater and cooler, evaporative air cooler, etc., and its features and advancements have been discussed. Further, the influence of distinct input parameters on performance indices of dehumidifier, regenerator, and on the overall performance of LDECS has been addressed through the various state-of-the-art research results and summarized in the form of tables. At the end, the critical conclusion and the future scope of various promising technologies have been elaborated concisely.
