Abstract

a presente invenção refere-se a um método de controle de uma unidade de ejeção de capacidade variável (7) disposta em um sistema de refrigeração (1). é gerado um sinal de controle do ejetor para a unidade de ejeção (7), baseado em uma temperatura obtida e uma pressão obtida de refrigerante saindo de um permutador de calor que dissipa o calor (3), ou baseado em um sinal de controle da válvula de alta pressão para controlar um grau de abertura de uma válvula de alta pressão (6) disposta de modo fluido em paralelo com a unidade de ejeção (7). o sinal de controle do ejetor indica se a capacidade da unidade de ejeção (7) deve ser aumentada, diminuída ou mantida. a capacidade da unidade de ejeção (7) é controlada de acordo com o sinal de controle do ejetor gerado. o consumo de energia do sistema de refrigeração (1) é reduzido, ao passo que a pressão do refrigerante saindo do permutador de calor que dissipa o calor (3) é mantida a um nível aceitável.
