Abstract

a presente invenção impede a execução de descongelamento vazio em que a operação de descongelamento é iniciada quando nenhum gelo está presente em um trocador de calor externo. este aparelho de refrigeração é configurado de modo a iniciar a operação de descongelamento para descongelar um trocador de calor externo (13) quando, além de uma primeira condição exigida sendo satisfeita em que um estado durante o qual uma diminuição contínua na temperatura de um trocador de calor interno detectado por um sensor de temperatura de trocador de calor interno (33) continua por um primeiro tempo determinado, uma segunda condição exigida é satisfeita em que um estado durante o qual uma diminuição contínua na temperatura de um trocador de calor externo detectado por um sensor de trocador de calor externo (23) continua por um segundo tempo predeterminado.the present invention prevents the execution of empty defrost in which the defrosting operation is initiated when no ice is present in an external heat exchanger. this refrigeration appliance is configured to initiate the defrosting operation to defrost an external heat exchanger (13) when, in addition to a first required condition being satisfied in which a state during which a continuous decrease in the temperature of a heat exchanger internal heat detected by an internal heat exchanger temperature sensor (33) continues for a determined first time, a second required condition is satisfied in which a state during which a continuous decrease in the temperature of an external heat exchanger detected by a external heat exchanger sensor (23) continues for a second predetermined time.
