The application relates to a cooling system, the cooling system having: an evaporator, a first compressor, a second compressor, a cooling component, an expansion device and a line system that connects the evaporator, the first compressor, the second compressor, the cooling component and the expansion device to one another. The cooling system includes a refrigerant, wherein the refrigerant comprises carbon dioxide. The first compressor and the second compressor are arranged in series with one another. The application also relates to a corresponding laboratory instrument.

Cooling system and laboratory instrument having a cooling system

The present invention relates to a centrifuge, in particular a laboratory centrifuge, comprising a rotor which is rotatably mounted in an interior of a rotor chamber and is designed to accommodate sample vessels, a drive motor to set the rotor in rotation, and a cooling device which is designed to dissipate heat from the interior of the rotor chamber via a coolant, the cooling device being designed to use an elastocaloric effect and having at least one cooling unit which comprises an elastocaloric material arranged between a counter block and a punch, the punch being designed to periodically apply a force to the elastocaloric material and then to let the elastocaloric material relax again, the cooling device being designed to transfer both heat from the elastocaloric material to the coolant and from the coolant to the elastocaloric material. The present invention also relates to a method for cooling an interior of a rotor chamber of such a centrifuge.
