Cycles frigorifiques à absorption ammoniac-eau actionnés par des sources de chaleur à basse température.

Refrigeration absorption cycles with ammonia-water driven by low temperature heat sources.

Auteurs : VALLES M., BOER D., CORONAS A.

Résumé

At present much interest is being shown in cycles working with low temperature heat sources. They can use low temperature waste heat or extract more heat from waste streams and use it to produce cold. The authors are interested in producing of subzero temperatures (-5 deg C). Cycles are simulated with generator temperatures between 60 and 110 deg C and absorber temperatures between 35 and 50 deg C and compared to a single effect cycle. The most suitable working pair for this application is the natural working fluid, ammonia with water as absorbent, associated to advanced absorption cycles which are adapted to these specific conditions. The cycles studied are the double lift series flow, the double lift vapour exchange and a triple lift cycle.
