Abstract

APARELHO DE REFRIGERAÇÃO. A invenção refere-se a um aparelho de refrigeração (1) que compreende um primeiro compartimento (10) e um segundo compartimento (12) para receber produtos alimentares, sendo o que dito primeiro compartimento (10) e o dito segundo compartimento (12) estão separados um do outro. É proporcionado um sistema de refrigeração (30) compreendendo um evaporador (38) para resfriar ar e um ventilador (72) força o ar resfriado para os compartimentos (10, 12). O ventilador (72) compreende um rotor (82) com um eixo geométrico de rotação (X) que está inclinado em relação à direção vertical (V). Um primeiro conjunto de ventilação (50a) está apto para canalizar o ar resfriado forçado pelo dito ventilador (72) para dentro do primeiro compartimento (10) e um segundo conjunto de ventilação (50b) está apto para canalizar o ar resfriado forçado pelo ventilador (72) para dentro do segundo compartimento (12), sendo que o primeiro conjunto de ventilação (50a) e o ventilador (72) estão associados ao dito primeiro compartimento (10). O aparelho de refrigeração (1) compreende um duto de interconexão (110) configurado para conectar o primeiro conjunto de ventilação (50a) ao segundo conjunto de ventilação (50b), sendo que o dito duto de interconexão (110) está disposto a jusante do ventilador (72) para transportar o ar resfriado forçado pelo ventilador (72) em direção ao dito segundo conjunto de ventilação (50b). O duto de interconexão (110) estende-se ao longo de um eixo geométrico principal (Y) que está inclinado em relação ao eixo geométrico de rotação (X) do rotor (82) de um ângulo (W) compreendido entre 70º e 110º, preferencialmente um ângulo (W) compreendido entre 85º e 100º, mais preferencialmente um ângulo (W) igual a 95º.
