Abstract

A presente invenção refere-se a métodos de controle de compressor de dupla sucção para aplicação em sistemas de refrigeração, capazes de atender às diferentes demandas por custo, eficiência e controle das temperaturas através de técnicas de níveis de complexidade e diferentes configurações dos elementos da malha de controle (sensores de temperatura, atuadores, controladores, etc). Dentre as soluções propostas, descreve-se um método de controle e ajuste das capacidades de refrigeração de um sistema de refrigeração equipado com compressor de dupla sucção, o sistema de refrigeração compreendendo compartimentos a serem refrigerados e compreendendo ao menos dois evaporadores (20) posicionados nos compartimentos a serem refrigerados (60,70), o compressor (10) de dupla sucção sendo controlável para alternar a sua capacidade de compressão, o método compreendendo etapas de (i) Continuamente medir ao menos uma temperatura proveniente de um sensor de temperatura (SET.SCT) associado a, ao menos um dos evaporadores (20) e (ii) atuar na capacidade de compressão do compressor (10), a partir da medição da etapa (i).
