Abstract

"SISTEMA DE CICLO DE EJETOR". Em um sistema de ciclo de ejetor, o refrigerante gasoso quente descarregado de um compressor (100) é introduzido em um evaporador (300), através de uma passagem de desvio (700), desviando de um ejetor (400) e de um separador gás-líquido (500) em uma operação de descongelamento para derreter o gelo gerado no evaporador. Além do mais, um estrangulador (520) ou uma válvula de retenção (510) é provida em uma passagem de refrigerante (L1), do separador gás-líquido para um lado de entrada de refrigerante do evaporador. Conseq³entemente, na operação de descongelamento, o refrigerante gasoso quente proveniente do compressor pode ser precisamente introduzido no evaporador através da passagem de desvio sem fluir em direção ao separador gás-líquido.
