Abstract

resumo "dispositivo de refrigeração". a presente invenção refere-se ao problema de controlar o grau de superaquecimento em um dispositivo de refrigeração onde um refrigerante alcança com facilidade um estado super-resfriado antes alcançar uma evaporadora. durante o resfriamento, uma válvula de expansão interna (41) do dispositivo de refrigeração (10) controla a expansão de um refrigerante que flui para dentro de um trocador de calor interno (42) com base em um valor alvo de baixa pressão e um valor alvo do grau de superaquecimento para o lado de fluxo para fora do trocador de calor interno (42). o estado super-resfriado do refrigerante no lado de fluxo interno do trocador de calor interno (42) é detectado por meio de um sensor de temperatura de tubo de líquido interno (44) e um sensor de pressão de sucção (33). quando um dispositivo de controle interno (47) determina com base no resultado de detecção a partir do sensor de temperatura de tubo de líquido interno (44) e o sensor de pressão de sucção (33) que o refrigerante no lado de fluxo interno do trocador de calor interno (42) está no estado super-resfriado, o dispositivo de controle interno muda o ajuste de modo a elevar o valor alvo do grau de superaquecimento a partir de um primeiro valor alvo de grau de superaquecimento tsh1 a um segundo valor alvo de grau de superaquecimento tsh2.summary "cooling device". The present invention relates to the problem of controlling the degree of overheating in a refrigeration device where a refrigerant easily reaches a supercooled state before reaching an evaporator. during cooling, a cooling device internal expansion valve (41) (10) controls the expansion of a refrigerant flowing into an internal heat exchanger (42) based on a low pressure target value and a target of the degree of overheating to the outflow side of the internal heat exchanger (42). The supercooled state of the refrigerant on the internal flow side of the internal heat exchanger (42) is detected by means of an internal liquid tube temperature sensor (44) and a suction pressure sensor (33). when an internal control device (47) determines based on the detection result from the internal liquid tube temperature sensor (44) and the suction pressure sensor (33) that the refrigerant on the internal flow side of the exchanger If the internal heat exchanger (42) is in the supercooled state, the internal control device changes the setting so as to raise the overheat degree target value from a first tsh1 overheat degree target value to a second overheat target value. degree of overheating tsh2.
