Abstract:In this study, the modeling and performance analysis of ammonia-water absorption refrigeration system for ocean-going fishing vessels has been investigated. According to ammonia water solution saturated vapor and saturated liquid state equation, the thermodynamic properties of the refrigerant is studied. Based on the basic principles of the ammonia-water absorption refrigeration cycle, a mathematical model of the ammonia-water absorption refrigeration cycle is established so that the thermodynamic parameters of each state point and the heat load of each device can be calculated and then the coefficient of performance (COP), exeretic coefficient of performance (ECOP) for the system can also be calculated. Considering heat source temperature, cooing water temperature and refrigerating temperature, the effects of them on COP and ECOP are discussed by some simulation examples. After these calculations, some graphics indicating the change of the variables with the temperature parameters.
