Abstract

resumo patente de invenção: "dispositivo de refrigeração". a presente invenção refere-se a um custo baixo um dispositivo de refrigeração com o qual uma concentração de óleo ou viscosidade de óleo apropriada que pode ser mantida facilmente para óleo de lubrificação no compressor, e com o qual o consumo de energia de espera pode ser reduzido. um compressor (40) comprime um refrigerante circulando entre um trocador de calor de recinto fechado (21) e um trocador de calor de recinto aberto (31). um aquecedor de cárter (46) aquece o óleo lubrificante no compressor (40). um dispositivo de controle (50) controla o aquecedor de cárter (46) de tal maneira que a temperatura do óleo lubrificante no compressor (40) alcança um valor de temperatura de óleo alvo que é obtido ao adicionar um valor de deslocamento de temperatura de óleo à temperatura de saturação do refrigerante no compressor (40).
