Abstract

a presente invenção previne a redução de segurança e refere-se a aparelho de refrigeração para executar ciclo de refrigeração em circuito refrigerante (rc) de sistema de ar condicionado (100), o dispositivo de refrigeração com trocadores de calor externo (20) e interno (32), primeira (41), segunda (42) e terceira válvulas de controle (43) e unidade de ajuste de pressão (44). a primeira (41) e a segunda (42) bloqueiam o fluxo de fluido refrigerante quando estão completamente fechadas e dispostas em caminho de fluxo de fluido refrigerante do lado do gás (gl). este caminho (gl) entre os trocadores de calor externo (20) e interno (32). a terceira (43) bloqueia o fluxo de fluido refrigerante quando está completamente fechada e disposta em caminho de fluxo de fluido refrigerante do lado do líquido (ll). este caminho (ll) entre os trocadores de calor externo (20) e interno (32). unidade de ajuste de pressão (44) ajusta a pressão do fluido refrigerante em caminho de fluxo de fluido refrigerante do lado interno (il). este caminho (il) entre as primeira (41) e segunda válvulas (42), ou entre a terceira (43) e o trocador (32). a unidade de ajuste de pressão (44) inclui válvula de ajuste de pressão (45). esta (45) desvia o fluido refrigerante presente no caminho de fluxo de fluido refrigerante do lado interno (il) para caminho do lado externo (ol). este caminho (ol) entre as primeira (41) e segunda válvulas (42), ou entre a terceira válvula (43) e o trocador (20).
