Abstract

Trata-se de um compressor de refrigerante (12) para sistemas de refrigeração que compreende um eletromotor (60), pelo menos dois bancos de cilindro (42) e uma unidade de controle de potência (70) mecânica para a ativação e desativação de pelo menos um dos bancos de cilindro (42), para ativar ou desativar sua emissão de refrigerante, sendo que, o compressor de refrigerante (12) pode ser operado para a operação em estados de potência parcial em pelo menos dois modos de operação (B) diferentes, dos quais cada um dos outros modos de operação prevê diferentes ativações ou desativações dos bancos de cilindro (12), sendo que ao compressor de refrigerante (12) é atribuído um conversor de frequência (132) para o controle do número de rotações do eletromotor (60), sendo que ao compressor de refrigerante (12) é atribuído um controle de estado operacional (130), que, de forma correspondente a um sinal de solicitação de potência fornecido a esse para a operação do compressor de refrigerante (12) no estado de potência parcial, que corresponde a esse sinal de solicitação de potência (LA), opera o compressor de refrigerante (12) em um modo de operação selecionado a partir de pelo menos dois diferentes modos de operação (B) diferentes, assim como, um número de rotações ajustado ao modo de operação para a realização desse estado de potência parcial.
