Cycle à absorption rentable améliorant l'interface charge/refroidisseur à absorption à chauffage direct et à double effet.

Cost-effective absorber cycle improves DFA chiller/load interface.

Auteurs : MECKLER M.

Résumé

The paper describes an enhanced absorption cycle utilizing a vapor recompression absorber (VRA), which can either be retrofitted into an existing or constructed as part of a new direct-fired double-effect absorption (DFA) chiller. The VRA employs uniquely configured concentric heat and mass transfer surfaces and is powered by a relatively small electric motor blower. Since the heat of compression is recovered as latent heat of evaporation, the VRA unit operates essentially as an absorber/low pressure differential heat pump while increasing the volume of the refrigerant water and further concentrating the absorbent, thereby decreasing the supply temperature to 2.2 °C or lower. This permits a higher chiller temperature-differential than presently possible while maintaining approximately the same overall system COP.
