Abstract

The cooling system may dehumidify and cool the indoor air by using the ejector, the ejector membrane, the evaporation chamber, and the indoor dehumidifying membrane. In addition, the coefficient of performance of the cooling system may be improved by cooling the refrigerant using evaporation latent heat generated in the evaporation chamber by the suction force of the ejector and cooling the indoor air using the refrigerant. In addition, by using solar heat to generate high-temperature and high-pressure steam and supply the generated steam to the ejector, energy use efficiency may be improved. In addition, since the temperature of the steam generated in the steam generating portion may be lowered by arranging and using the two first and second ejectors in multiple stages, energy efficiency may be further improved by reducing the consumption of the heat source required for steam generation.
