A new concept for NH3-H2O absorption refrigeration system.

Summary

Ammonia is the most frequent used refrigerant for the industrial applications (food cooling mainly), but also for air conditioning. Compression systems have been used with equipment produced in Romania (compressors, condensers, evaporators and auxiliary equipment). An ammonia system has been used for the most important building hosting social and cultural events, only compressors being imported, and the rest of the equipment being produced in Romania. After the sixties of the last century very high capacity (2-20MW) absorption ammonia-water systems have been conceived and produced, especially for the chemical industry. Some of these systems are still in operation where the industry still exists. In the same period research started to develop refrigeration systems using renewable energy. Professors and researchers from the Building University of Bucharest-UTCB, and from the Polytechnic University of Bucharest (CHIRIAC et al., 1983) have realized a solar driven ice manufacturing system with a capacity of 20000 kg ice/day. The paper presents a new concept about ammonia-water solution as a result of researches carried out by the authors in the field of absorption refrigeration for medium and low capacity and renewable energy sources. The paper presents the schematics and the construction characteristics, as a starting point before doing the experimental measurements and sees the results for different operational conditions.
