This paper describes the recent status of R&D on desiccant cooling in Japan. A number of research projects on desiccant cooling have been carried out since the oil crisis, in man.y cases financially supported by the government. The desiccants used include LiCl, silica gel, and zeolite, and the desiccant carriers are rotary heat exchangers or beds. In man.y cases, solar energy is used as the heat source for the regeneration of desiccants. In other cases, the performance of solar desiccant cooling systems has been observed.
