Abstract
"MéTODO PARA REFRIGERAçãO, COMPOSIçãO REFRIGERANTE E SISTEMA DE AR CONDICIONADO". A presente invenção descreve uma combinação nova de refrigerante/lubrificante para uso em aplicações de refrigeração e ar condicionado fixas e móveis. Nessas aplicações, o refrigerante e o lubrificante devem ser solúveis entre si (ex: miscíveis) para garantir a adequada circulação de lubrificante do compressor, pelo condensador, dispositivo de expansão e evaporador e de volta ao compressor. A circulação insuficiente de lubrificante resultará em falha no compressor. A solubilidade a baixa temperatura é particularmente importante para garantir o fluxo de lubrificante pelo evaporador frio. Além disso, a combinação de lubrificante e refrigerante deve ser estável na presença de aço, e metais contendo alumínio e cobre. A presente invenção descreve a combinação de refrigerante difluoroetano (R152a) e lubrificantes polares oxigenados, particularmente polialquileno glicóis (PAGs) e poliolésteres (POEs) que podem ser utilizados como substitutos imediatos de R134a.
