Abstract

SE PREVE UN MECANISMO DE REFRIGERACION QUE TIENE AL MENOS DOS COMPARTIMIENTOS DE REFRIGERACION (26, 30), TENIENDO CADA COMPARTIMIENTO SU PROPIA PUERTA DE ACCESO (24, 28). EL MECANISMO COMPRENDE UN UNICO EVAPORADOR (38) SITUADO EN UN PLENO (84) EL CUAL ESTA SELECTIVAMENTE EN COMUNICACION CON CADA UNO DE LOS COMPARTIMIENTOS (26, 30), UN UNICO COMPRESOR (34), PREFERENTEMENTE ACTIVADO POR UN MOTOR DE VELOCIDAD VARIABLE , Y UN CIRCUITO DE REFRIGERANTE QUE COMPRENDE UNA SERIE DE CONDUCTOS PARA PROPORCIONAR UN FLUJO DE REFRIGERANTE AL EVAPORADOR (38) Y COMPRESOR (34). UN PRIMER DISPOSITIVO DE RESTRICCION (54) ESTA PREVISTO EN EL CONDUCTO QUE CONECTA EL COMPRESOR (34) CON EL EVAPORADOR (38), FUNCIONANDO EL DISPOSITIVO DE RESTRICCION (54) EN UN PRIMER NIVEL DE PRESION. UN SEGUNDO DISPOSITIVO DE RESTRICCION (56) TAMBIEN ESTA PREVISTO EN EL CONDUCTO QUE CONECTA EL COMPRESOR CON EL EVAPORADOR, PREFERENTEMENTE EN PARALELO CON EL PRIMER DISPOSITIVO DE RESTRICCION (54), OPERANDO EL SEGUNDO DISPOSITIVO DERESTRICCION A UN NIVEL DE PRESION MAYOR QUE EL PRIMER NIVEL DE PRESION. TAMBIEN UNA VALVULA (76) O VALVULAS PREFERENTEMENTE DEL TIPO DE ENGANCHE, ESTA POSICIONADA EN EL CIRCUITO DE REFRIGERANTE PARA DIRIGIR REFRIGERANTE A UNO DE LOS DISPOSITIVOS ELEGIDO DE RESTRICCION (54, 56), O CERRANDO AMBOS CIRCUITOS POR COMPLETO. UN MATERIAL DE CAMBIO DE FASE (62) PUEDE SER USADO EN EL CIRCUITO DE REFRIGERACION PARA MEJORAR LA EFICACIA DE ENERGIA DEL SISTEMA. TAMBIEN, CON ESTE SISTEMA, LOS COMPARTIMIENTOS (26, 30) DEL MECANISMO REFRIGERADOR PUEDE FUNCIONAR BIEN DENTRO DE UN CONGELADOR O EN MODO DE REFRIGERACION DE ALIMENTOS FRESCOS SEGUN SE DESEE, PROPORCIONANDO COMPARTIMIENTOS DE REFRIGERACION CONVERTIBLES.
