Abstract

DISPOSITIVO DE DESCONGELACION PARA UN APARATO FRIGORIFICO.LA DESCONGELACION DEL PRIMER EVAPORADOR QUEDA CONFIADA FUNDAMENTALMENTE A SU DESCONGELACION NATURAL, QUE TIENE LUGAR EN CADA CICLO DE FUNCIONAMIENTO DEL APARATO FRIGORIFICO DURANTE EL PERIODO EN QUE EL COMPRESOR (3) SE ENCUENTRA PARADO. DISPONE DE MEDIOS ADICIONALES DE DESCONGELACION (4) PARA APORTAR AL PRIMER EVAPORADOR SOLO LA CANTIDAD DE CALOR ADICIONAL NECESARIA PARA ASEGURAR EL FINAL DE LA DESCONGELACION ANTES DE QUE LA TEMPERATURA EN EL SEGUNDO DEPARTAMENTO SOBREPASE UN VALOR LIMITEPREFIJADO.
