Abstract

refrigerador e método de controle de um compressor de velocidade variável. refrigerador (200, 210) compreendendo um compartimento (13a) para armazenar produtos alimentícios; um sistema de resfriamento (200; 210) compreendendo um evaporador (12a), um condensador (14) e um compressor de velocidade variável (10), sendo o sistema de resfriamento (200; 210) adaptado para passar por um ciclo de refrigeração em certos intervalos. um sistema de controle (11) está configurado para controlar o compressor de velocidade variável (10) durante o ciclo de refrigeração, sendo o sistema de controle (11) baseado em uma velocidade mínima (36) e uma velocidade requerida (22), em que o sistema de controle (11) está configurado para definir a velocidade do compressor (35) como a velocidade mais alta dentre ambas a velocidade mínima (36) e a velocidade requerida (22). esse sistema de controle (11) proporciona um desempenho aprimorado do sistema de resfriamento (200, 210), mantendo um equilíbrio de diferentes temperaturas dentro do refrigerador (100, 110).
