Abstract
é descrito um método para controlar um sistema de compressão a vapor (1) que compreende um ejetor (6). no caso de uma diferença de pressão entre uma pressão prevalecente no receptor (7) e uma pressão de refrigerante que sai do evaporador (9) diminuir abaixo de um primeiro valor limite inferior, a pressão de refrigerante que sai do trocador de calor de rejeição de calor (5) é mantida em um nível que é ligeiramente superior ao nível de pressão, o que fornece cop ideal. desse modo, o ejetor (6) pode operar em temperaturas ambientes inferiores e a eficiência de energia do sistema de compressão a vapor (1) é aprimorada.
