Abstract

EL AJUSTE SE CONSIGUE DE TAL MODO, QUE LA VALVULA DE EXPANSION SE APLICA PRIMERO PARA UN MEDIO (R{SUB,0}) REFRIGERANTE BASICO CON UNA ABERTURA ({DL}T{SUB,OH}) DE SOBRECALENTAMIENTO ESTATICO, SUSTANCIALMENTE CONSTANTE EN UN CAMPO DE TRABAJO PREVIAMENTE DETERMINADO A LA TEMPERATURA DEL EVAPORADOR, Y CUANDO EL CIRCUITO DE MEDIO REFRIGERANTE SE LLENA CON EL MEDIO (R{SUB,1}, R{SUB,2}) REFRIGERANTE DE SUSTITUCION, QUE DIFIERE DEL REFRIGERANTE (R{SUB,0}), SE AJUSTA LA TENSION PREVIA DE SU RESORTE (46) DE AJUSTE DE ACUERDO CON UNA ESPECIFICACION ADECUADA A LA DIFERENCIA ENTRE LAS CURVAS DE PRESION DE VAPOR DEL LIQUIDO REFRIGERANTE DE SUSTITUCION Y AQUELLAS DEL LIQUIDO REFRIGERANTE BASICO.
