Abstract

Fremgangsmåten og innretningen ifølge oppfinnelsen benyttes til å avkjøle og/eller kondensere et fluid. Fluidet (1) bringes i indirekte varmeutveksling med minst en kuldemiddelstrøm (4) i et varmevekslersystem (2). Kuldemiddelstrømmen føres i et kuldekretsløp. I kuldekretsløpet føres kuldemiddelstrømmen gjennom en kuldemiddelresirkulasjonslinje (5a, 5b), som er anordnet nedstrøms til den indirekte varmevekslingen i varmevekslersystemet (2), til en kretsløpskom-pressors (6) innløp, hvor kuldemiddelstrømmen komprimeres i kretsløpskompressoren (6) og er i det minst delvis avkjølt (7), utvidet (8) og igjen ført inn i varmevekslersystemet (2). Nedstrøms til den indirekte varmeveksling i varmevekslersystemet (2), og oppstrøms av komprimeringen i kretsløpskompressoren (6) er kuldemiddelstrømmen ledet gjennom en varmeakkumulator (9), som er anordnet i kuldemiddelresirkulasjonslinjen (5a, 5b).The method and device according to the invention are used to cool and / or condense a fluid. The fluid (1) is brought into indirect heat exchange with at least one refrigerant stream (4) in a heat exchanger system (2). The refrigerant stream is fed into a refrigerant circuit. In the refrigerant circuit, the refrigerant stream is passed through a refrigerant recirculation line (5a, 5b), which is arranged downstream of the indirect heat exchange in the heat exchanger system (2), to the inlet of a circuit compressor (6), where the refrigerant stream is compressed in the circuit (at least 6). partially cooled (7), expanded (8) and re-introduced into the heat exchanger system (2). Downstream of the indirect heat exchange in the heat exchanger system (2), and upstream of the compression in the circuit compressor (6), the refrigerant stream is passed through a heat accumulator (9), which is arranged in the refrigerant recirculation line (5a, 5b).
