Abstract
A method and apparatus for cooling a load using liquid nitrogen conveyed in a circuit are provided. Cooled liquid nitrogen is used for cooling the liquid nitrogen conveyed in the circuit. A first proportion of the liquid nitrogen is cooled in an open cooling system and a second proportion is cooled in a closed cooling system using one or more cooling units. The open cooling system and closed cooling system are used for cooling of a power supply having a first end and a second end. The open cooling system is arranged at the first end and the closed cooling system is arranged at the second end. Cooling power is provided in a first time period as a first, smaller amount of total cooling power and in a second time period as a second, higher amount of total cooling power. A first proportion of the amount of total cooling power is provided by means of the open cooling system and a second proportion is provided by means of the closed cooling system. The first proportion in the first time period is set to a lower value than in the second time period.
