Abstract

Patente de Invenção: "MéTODO E APARELHO PARA CONTROLE DE SISTEMA DE REFRIGERAçãO QUE TêM REGULADORES ELETRôNICOS DE PRESSãO DO EVAPORADOR". é proporcionado um método e aparelho para controle de sistema de refrigeração. O sistema de refrigeração inclui uma pluralidade de circuitos com cada circuito tendo pelo menos uma caixa de refrigeração. Um regulador eletrônico da pressão do evaporador está em comunicação com cada circuito e é operável para controlar a temperatura do circuito correspondente. Uma pluralidade de compressores é também fornecida com cada compressor fazendo parte de uma bancada de compressor. Um sensor de pressão é usado para medir a pressão de sucção da bancada de compressor. Um sensor está em comunicação com cada circuito e é operável para medir um parâmetro de cada circuito. Um controlador controla cada regulador eletrônico de pressão do evaporador e a pressão de sucção baseada nos parâmetros medidos de cada circuito.
