Abstract

"COMPOSIçãO REFRIGERANTE, COMPOSIçãO LUBRIFICANTE PARA UTILIZAçãO COM UM REFRIGERANTE HIDROCARBONO HALOGENADO EM APARELHOS DE REFRIGERAçãO POR COMPRESSãO, PROCESSO DE PRODUçãO DE REFRIGERAçãO, PROCESSO DE PRODUçãO DE CALOR E PROCESSO DE RETORNO DE óLEO" São descritas composições refrigerantes que contêm agentes de retorno de óleo hidrocarbonos que solubilizam lubrificantes de óleos sintéticos e minerais com refrigerantes com base em hidrofluorocarbonos e hidrofluorocarbonos/hidroclorofluorocarbonos. Esses agentes de retorno de óleo hidrocarbonos, que contêm de 7 a 16 átomos de carbono, na forma de pequena proporção de uma composição refrigerante geral, permitem retorno eficiente de lubrificantes de óleo sintético e mineral de regiões não compressoras de volta a uma região compressora, em um sistema de refrigeração que opera com refrigerantes com base em hidrofluorocarbonos e hidrofluorocarbonos/hidroelorofluorocatonos."REFRIGERANT COMPOSITION, LUBRICANT COMPOSITION FOR USE WITH A HALOGENATED HYDROCARBON REFRIGERANT IN COMPRESSION REFRIGERATION APPLIANCES, COOLING PRODUCTION PROCESSES THAT ARE REPLACEMENT OF HEATING PRODUCTION PROCESSING AND REFRIGERATION PROCESSES which solubilize lubricants of synthetic and mineral oils with refrigerants based on hydrofluorocarbons and hydrofluorocarbons / hydrochlorofluorocarbons. These hydrocarbon oil return agents, which contain 7 to 16 carbon atoms, in the form of a small proportion of a general refrigerant composition, allow efficient return of synthetic and mineral oil lubricants from non-compressing regions back to a compressing region, in a refrigeration system that operates with refrigerants based on hydrofluorocarbons and hydrofluorocarbons / hydroelorofluorocarbons.
