Evaporation directe dans les systèmes frigorifiques utilisant l'eau comme fluide frigorigène.

Direct evaporation in refrigeration systems with water as refrigerant.

Auteurs : ALBRING P., BURANDT B., HEINRICH G.

Résumé

Direct evaporation in refrigeration systems using water is characterised by the fact that a mixture of refrigerant and cooling medium is injected into the evaporator. This mixture of refrigerant and cooling medium can be expanded either: 1) into the liquid (cooling medium); or 2) into the vapour space. The paper will consider the second alternative. The process characteristics of refrigerant and outer mass flows is explained by way of the lg p-h-diagram. The aim of the development of such direct evaporators is to minimise the temperature difference between the cooling medium outlet temperature and the saturation temperature at droplet-free vapour flow into the compressor. Test results will be presented.
