ABSTRACT

Ejector cooling systems have the advantages of low initial costs and high reliability, absence of the need for maintenance, simple design, and an absence of moving parts. Yapici and Akkurt experimentally investigated an ejector cooling system driven by hot water and using R123 as the working fluid of the cycle. When looking to enhance the performance of cooling systems, several combined technology systems have been proposed and investigated. Peterson and Howell patented a hybrid desiccant-vapor compression cycle (VCC) system. In this system, the VCC was used for air conditioning, while the liquid desiccant allowed for the simulta­neous cooling and dehumidification of process air. Elakdhar et al. developed a model with Fortran to simulate the behavior of a hybrid VCC-ejection system used for domestic purposes. Jiang et al. compared the thermo-economic performance of a hybrid absorption-ejector refrigeration system and a conventional double-effect absorption chiller.
