Desiccant cooling system (DCS) is alternate suitable option against conventional cooling system in humid climates. A typical system combines a dehumidifier that uses dry desiccant wheel, with direct or indirect evaporative systems and a sensible cooling system. DCS is the environmental protection technique for cooling purpose of the building. This system reduces the CFC level in the environment because it restricts the use of conventional refrigerant. In this paper, all the working principles and expected research areashave been discussed. Through detailed literature survey it has been observed that a desiccant cooling system may be a suitable option for thermal comfort in the climate where the humidity is higher. Thedesiccant cooling system (DCS) has proven their feasibility and cost saving in the field of air conditioning. This review provides a brief overview on the development of desiccant cooling system in different fields. Finally, concluding remarks regarding further development of desiccant cooling for thermal comfort are also provided. This technology is economically feasible and optimizes with low cost. This review is useful for making opportunities to further research in different areas of desiccant cooling system.
