Simulation of an ammonia-water absorption cycle using exchanger effectiveness

Dynamic simulation of an ammonia-water absorption refrigeration system

A dynamic model of a single-effect absorption refrigeration cycle has been developed. Modeling of the cycle performance requires thermodynamic properties which are obtained from equations of state for refrigerant-absorbent mixtures. The transient response of the absorption refrigeration cycle is investigated using mass, momentum and energy balances for the different parts of the system. Some de...

Analysis and Simulation of the Effect of Turbine Inlet Temperature on Thermodynamic Performance of the Water – Ammonia Combined Cycle

Due to the importance of power generation cycles including combined cycle, many studies have been done in recent years and many researchers have been tried to optimize these cycles by using of existing methods. In this study, the Water-Ammonia cycle is investigated in the combined-cycle of the Water-Ammonia, working dual Water-Ammonia mixture is used as the works fluid. This cycle can be used f...

Integration of an Ammonia-water Absorption Refrigeration System with a Marine Diesel Engine: A Thermodynamic Study

This paper examines through a thermodynamic analysis the feasibility of using waste heat from marine Diesel engines to drive an ammonia-water absorption refrigeration system. An energy balance of a diesel engine shows that sufficient waste heat is provided. The results illustrate that higher performance of the system is obtained at high generator and evaporator temperatures and also at low cond...
