Food refrigeration is one of the largest applications in the refrigeration market. At present, this market is dominated by mechanical vapor compression systems. The availability of aqua‐ammonia absorption refrigeration systems provides an alternative to vapor compression systems. The study describes the aqua‐ammonia absorption refrigeration system. A detailed mathematical model for simulating its operation is presented with complete sources of H 2 O‐NH 3 mixture thermodynamic data. Based on the model, a computer software is developed. With this software, the performance characteristics of the aqua‐ammonia absorption system are analyzed. Optimizing the system performance is also carried out and some optimum results are presented.
