Abstract

Patente de Invenção: "CONDICIONADOR DE AR". Uma válvulade controle (CV) é localizada em um compressor de deslocamentovariável que é instalado em um circuito refrigerante. A válvula decontrole (CV) opera de maneira que a diferença de pressão entre oprimeiro e segundo pontos de monitoração de pressão (Pl, P2) nocircuito refrigerante procure um valor alvo predeterminado. Oprimeiro ponto de monitoração de pressão (Pl) está localizado emuma câmara de pressão (22) do compressor. O segundo ponto demonitoração de pressão (P2) está localizado em uma tubulação defluxo (36) que se estende da câmara de descarga (22). A pressãoestática do refrigerante na câmara de descarga é introduzida emuma válvula de controle (CV) do primeiro ponto de monitoração depressão (P1). Uma pressão que inclui a pressão estática e pressãodinâmica do refrigerante na tubulação de fluxo (36) é introduzida naválvula de controle (CV) do segundo ponto de monitoração depressão (P2). Como um resultado, o deslocamento do compressor éseguramente controlado sem ser afetado pela carga térmica de umevaporador (33).
