摘要： The invention relates to a method for cooling a fluid such as helium for supplying a fluid consumer, the fluid flowing in a cyclic manner successively through a compression stage (4), a fluid pre-cooling and/or cooling stage (5, 6), and an interface (1) for supplying the fluid to the consumer and collecting the fluid from the consumer. A first portion of the fluid from the pre-cooling and/or cooling stage is directed towards the interface (1), a second portion of the fluid can be directed to the pre-cooling and/or cooling stage (5, 6) based on whether the thermal load required by the consumer is low or high, and a third portion of the fluid is cooled and directed towards the accumulator (26) adapted for alternatively storing said fluid or, based on whether the thermal load required by the consumer is low or high, for delivering an amount of fluid already stored in order to cool down the first portion of the fluid directed towards the interface (1).
