Abstract

"PROCESSO PARA OPERAR UM SISTEMA DE VENDA REFRIGERADO E SISTEMA DE VENDA REFRIGERADO DE ALIMENTOS A MéDIA TEMPERATURA". Um sistema de venda refrigerado ( 10 ) inclui um compressor ( 20 ), um condensador ( 30 ), um mostrador ( 100 ) que possui um evaporador ( 40 ), um dispositivo de expansão ( 50 ) e um dispositivo de controle de pressão de evaporador ( 60 ) conectado em um circuito fechado de agente refrigerante através de linhas de agentes agente refrigerantes ( 12, 14, 16 e 18 ). O dispositivo de controle de pressão de evaporador ( 60 ) opera para manter a pressão no evaporador a uma pressão de ponto de ajuste de modo a manter a temperatura do agente refrigerante que se expande de um líquido para um vapor dentro do evaporador ( 40 ) a uma temperatura desejada. Um controlador ( 90 ), associado operacionalmente com o dispositivo de controle de pressão de evaporador ( 60 ), mantém a pressão de ponto de ajuste a uma primeira pressão para o agente refrigerante, equivalente a uma primeira temperatura de agente refrigerante durante um primeiro modo de refrigeração, e a uma segunda pressão para o agente refrigerante, equivalente a uma segunda temperatura de agente refrigerante, aproximadamente, 1, 1a, aproximadamente, 6,7<198>C mais quente do que a primeira temperatura, durante um segundo modo de agente refrigerante. O controlador ( 90 ) seq³ência entre o mencionado primeiro modo de refrigeração e o mencionado segundo modo de refrigeração.
