Recent developments in plate exchangers: ammonia/carbon dioxide cascade condensers.

Auteurs : AYUB Z., KHAN M. S., JOKAR A., et al.

Résumé

The use of carbon dioxide and ammonia in low temperature cascade systems is gaining momentum in the industrial refrigeration market. The use of plate exchanger as cascade condenser is a viable option due to the high thermal efficiency and smaller foot print characteristics of such exchangers. There is a lack of reliable data in open literature on condensation of carbon dioxide and evaporation of ammonia in such heat exchangers. This paper presents the latest research on condensation of carbon dioxide and evaporation of ammonia in various corrugation angle plate exchangers at different saturation temperature and heat/ mass flux. The data are reduced to generalized empirical correlations to be used as design tool by engineers. It also discusses the mechanical aspects of plate exchanges and their suitability in cascade systems.
