Working fluids for mechanical refrigeration.

Author(s) : CAVALLINI A.

Summary

During the last years industry has scrutinised and proposed a number of new synthesised products as immediate drop-in or long term replacements for fluids noxious to the environment. Together with some single-component new generation refrigerants, quite a few two-component, three-component or even four-component mixtures, both with zeotropic and azeotropic behaviour, are being considered. The main issues associated with the use of the new generation refrigerants are discussed, such as behaviour with oil; flammability; efficiency use of temperature glides, fractionation and heat transfer degradation with zeotropic mixtures. The full environmentally friendly option of resorting to natural fluids is also considered (hydrocarbons, ammonia, carbon dioxide, water and air).
