Abstract

The performance of an absorption water chillier driven by solar water heater at Egypt climate conditions was investigated. This study is implemented on a single stage absorption machine using LiBr-water working fluid to afford 8.5 ton cooling load for ABK BANK. The thermodynamic model for absorption water chillier was developed. A simulation code using Engineering Equation Solver (ESS) was developed, and was validated with data in literature. Thermodynamic analysis is assisted by the energy and mass balance of all system components. To assure the validation, the relationship between COP and both of condenser temperature and evaporator temperature was investigated. A study of case was also undertaken for the city of Cairo, Egypt. It was found that the proper working temperature of the generator for this case was 80 0C.
