Abstract

"PROCESSO PARA IMPLEMENTAR UM CICLO TERMODINáMICO". A presente invenção refere-se a um novo ciclo termodinâmico para converter energia de uma fonte externa de fluxo de baixa temperatura em energia usável usando um fluido de trabalho compreendendo uma mistura de um componente de baixa ebulição e um componente de ebulição mais alta e que inclui um circuito de pressão mais alta e um circuito de pressão mais baixa. O ciclo é projetado para aperfeiçoar a eficiência do processo de extração de energia por meio da recirculação de uma porção de um fluxo de líquido para o resfriamento adicional. Os novos processos e sistemas termodinâmicos para se conseguir estas eficiências aperfeiçoadas são especialmente bem adequados para fluxos provenientes de fontes geotérmicas de baixa temperatura.
