Abstract

"MéTODO E APARELHO DE PARTIDA EM RESFRIADORES DE REFRIGERAçãO" A existência das condições de partida invertida em um resfriador de refrigeração (10) é identificada detectando o nível de líquido (64, 68) no evaporador do resfriador (20). Aquele nível de líquido (64, 68) é indicativo da localização da carga de refrigerante do resfriador na partida. Se o nível de líquido detectado (64, 68) está abaixo de um nível predeterminado, verifica-se que uma condição de partida invertida existe. As partidas fracassadas e as paralisações do sistema de resfriador são reduzidos ou impedidos.
