ShareChemical stability in systems with natural refrigerants.
Author(s) : BROESBY-OLSEN F.
Summary
In the general view, chemical reaction problems in refrigeration systems using natural refrigerants are surprisingly few and less complicated than with CFC, HCFC or HFC. Here, focus is on physical properties. The oil and polymer situation in transcritical carbon dioxide is quite unique. The solubility of the oil will change when carbon dioxide goes supercritical. Ammonia is a well-known refrigerant in large systems. In small systems, some problems arise, especially if the goal in future is hermetic or semihermetic systems. Known and possible chemical reactions in ammonia, carbon dioxide and hydrocarbon systems are discussed and compared to the situation in CFC, HCFC and HFC systems.
