Abstract

Patente de Invenção: <B> "PROCESSO PARA O CONTROLE DE UM SISTEMA DE REFRIGERAçãO, BEM COMO UM SISTEMA DE REFRIGERAçãO E VáLVULA DE EXPANSãO"<D>. Um processo para controle de um sistema de refrigeração (1) usa uma válvula de expansão (4), na qual um dos lados do elemento de regulagem está solicitado pela pressão do agente refrigerante no lado do evaporador e o outro lado do elemento de regulagem, pela pressão de vapor de um sistema de sensor (22), cuja temperatura de sensor é determinada pela temperatura de saturação do agente refrigerante e pelo abastecimento de calor por meio de um elemento de aqueciemnto (27). O abastecimento de calor é controlado na dependência de um valor de medição (superaquecimento ou nível de líquido). Além disso, está previsto um sistema de refrigeração (1) para realização de um controle desse tipo e uma válvula de expansão (4) como componente essencial. Desse modo, pode ser obtido um controle aperfeiçoado, de modo económico e de aplicação versátil.
