Abstract

DISPOSITIVO DESCONGELADOR PARA EL EVAPORADOR DE UNA INSTALACION FRIGORIFICA . SE CARACTERIZA PORQUE EL RECEPTOR DE ESCARCHA ES DE TIPO TERMICO Y ESTA DISPUESTO, REPECTO DE UNA SUPERFICIE DEL EVAPORADOR, A UNA DISTANCIA QUE CORRESPONDE AL ESPESOR ADMISIBLE DE UNA CAPA DE ESCARCHA. EL SISTEMA DE CONTROL DISPONE DE UN CIRCUITO DE COMPARACION, QUE DESENCADENA EL PROCESO DE DESCONGELACION CUANDO LA TEMPERATURA DEL PERCEPTOR DE ESCARCHA SOBREPASA UN VALOR DETERMINADO. ESTA FORMADO POR UN COMPRESOR (2) QUE TRASPORTA MEDIO REFRIGERANTE A UN CONDENSADOR (3) COMUNICADO POR UNA VALVULA (4) CON UN EVAPORADOR (5). EL EVAPORADOR ESTA DISPUESTO EN UN RECINTO REFRIGERADO (6). UN TERMOSTATO (7) ACTUA SOBRE EL COMPRESOR (2) EN FUNCION DE LA TEMPERATURA. UN SOPORTE (9) CONTIENE DOS PERCEPTORES (16, 17) QUE MIDEN LA TEMPERATURA DE LA ESCARCHA Y EL EVAPORADOR, Y QUE EN CASO DADO ACTUA SOBRE UNA RESISTENCIA CALEFACTORA.
