Liquid Desiccant Systems: A Review

Desiccant cooling systems have been considered as an efficient method of controlling moisture content in supply air. They do not use any ozone-depleting coolants and consume less energy as compared with the vapor compression systems. In hot and humid areas, the liquid desiccant air-conditioning systems based on evaporative cooling was proposed as an alternative to the traditional vapor compression systems due to its advantage in, removing the air latent load, friendly environment, removing of pollutants from the process air and reduction of the electrical energy. This paper provides an extensive review of liquid desiccant systems (LDSs). All the components of an LDS such as dehumidifier, regenerator, packing material and liquid desiccant properties along with its energy storage capabilities is mentioned. In addition, hybrid of LDSs with sensible cooling technologies is studied. At last, current problems in LDSs are also mentioned.
