Abstract

Patente de Invenção: "SISTEMA E MéTODO DE COMPRESSãO DE VAPOR". Um sistema de refrigeração de compressão de vapor e congelador (10) inclui um compressor (12), um condensador (14), um dispositivo de expansão e um evaporador (16) o qual inclui uma serpentina do evaporador que tem uma entrada e uma saída cuja serpentina está em relação de troca de calor com um meio de ar ao longo substancialmente do comprimento inteiro da serpentina. A entrada da serpentina do evaporador está em comunicação de fluxo com uma saída do dispositivo de expansão via uma linha de alimentação do evaporador (28). O dispositivo de expansão pode incluir uma válvula multifuncional (18) que coopera com a linha de alimentação do evaporador (28) para suprir a entrada da serpentina do evaporador com uma mistura de vapor e líquido refrigerante a uma velocidade linear e com relativas quantidades de vapor e de líquido as quais são suficientes para fornecer uma transferência de calor eficiente ao longo substancialmente do comprimento inteiro da serpentina, reduzindo substancialmente o acúmulo de gelo sobre a serpentina do evaporador e permitindo que o sistema seja operado sem requerer um ciclo de descongelamento durante um número substancialmente aumentado de ciclos de operação se comparado com os sistemas de refrigeração e de congelador convencionais operando nas mesmas condições de carga de resfriamento e de temperatura de evaporação.
