Abstract

COMPRENDE UN CONMUTADOR CONTROLADO POR UN TEMPORIZADOR PARA LA CONMUTACION CICLICA DESDE UNA PRIMERA POSICION EN LA QUE LA ALIMENTACION ELECTRICA SE SUMINISTRA A UN MOTOR COMPRESOR, HASTA UNA SEGUNDA POSICION EN LA QUE LA POTENCIA SE SUMINISTRA A UNA RESISTENCIA CALENTADORA DE DESCONGELACION Y EVAPORACION POR MEDIO DE UN CONMUTADOR DE TERMOSTATO CUANDO EL ULTIMO ESTA EN UNA POSICION QUE CORRESPONDE A LA TEMPERATURA INFERIOR DEL EVAPORADOR. EL CONMUTADOR TERMOSTATICO SALTA A UNA SEGUNDA POSICION EN RESPUESTA A LA MEDIDA DE UNA TEMPERATURA MAYOR EN EL EVAPORADOR. EL TEMPERIZADOR SE ALIMENTA CON CORRIENTE ELECTRICA POR MEDIO DEL CONMUTADOR CONTROLADO CUANDO EL ULTIMO ESTA EN SU POSICION PRIMERA, Y POR MEDIO DE UNA CONEXION EN SERIE DE LOS DOS CONMUTADORES CUANDO ESTA EN SU SEGUNDA POSICION. LA OPERACION DE DESCONGELACION AUTOMATICA SE LLEVA A CABO DE ACUERDO CON LA CONDICION ACTUAL DEL EVAPORADOR.
