Abstract

"PROCESSO PARA CONTROLAR PELO MENOS UM COMPRESSOR DE UM SISTEMA DE REFRIGERAçãO COM UM ACIONAMENTO DE VELOCIDADE VARIáVEL". A invenção usa um acionamento de velocidade variável ( VSD ) apenas sobre uma faixa de capacidade correspondente a condições de zero até ponto normal, e se as condições corresponderem a mais do que a corrente de ponto nominal, o VSD é desconectado e o compressor é conectado diretamente à linha elétrica. Esta abordagem permite usar um VSD de menor tamanho. Ao mesmo tempo, se houver diversos compressores operando na mesma máquina, apenas um VSD é necessário. O VSD aciona um primeiro compressor, de zero até a velocidade correspondente à freq³ência da linha. Controla, então, a comutação do primeiro compressor para ligação direta à linha elétrica ( DOL ) e desconecta o VSD do primeiro compressor. O VSD fica, então, disponível para acionar um segundo compressor. Este processo pode ser repetido através de múltiplos compressores.
