A cooling system (1), especially for cryopreserving biological samples (2), comprises a cooling chamber (100) delimited by a bottom area (110), side walls (120), and a top area (130), and a cooling device (200) for cooling the cooling chamber (100) using liquid nitrogen (220). At least one of the side walls (120) includes at least one predetermined wall element (125) which is a portion of at least one of the side walls and can be moved relative to the associated side wall (120) in such a way that a wall opening can be formed in said side wall (120). Methods for operating the cooling system (1) in case of an emergency are also described.

1. A cooling system for cryopreservation of biological samples, comprising: a cooling chamber, which is delighted by a floor area, side walls and a ceiling area,a protection device, wherein the protection device is in the cooling chamber is configured for creating a local protective atmosphere in a environment of an operator, and comprises: (a) a hood which is movable in the cooling chamber, or (b) movable partition walls, which are shiftable in the cooling chamber, and with which a chamber can be created in the cooling chamber;an external ventilation system for impingement of an interior of the hood or an interior of the chamber with heated air, anda cooling device, which is provided for cooling of the cooling chamber with liquid nitrogen, whereinat least one of the side walls contains at least one predetermined wall element, that is a subregion of the at least one of the side walls and that is movable relative to the at least one of the side walls such that a wall opening can be formed in the at least one of the side walls. 2. The cooling system according to claim 1, in which the at least one predetermined wall element has at least one feature selected from the group consisting of the at least one predetermined wall element is a detachable wall module of the at least one of the side walls,the at least one predetermined wall element is shiftable perpendicular to the at least one of the side walls,the at least one predetermined wall element can be manually moved by an operator, andthe at least one predetermined wall element can be separated from the at least one of the side walls. 3. The cooling system according to claim 1, in which are provided on an external side of the at least one of the side walls with the at least one wall element at least one of a docking device for an evacuation container, anda ramp, which falls off from a bottom edge of the wall element or the wall opening onto a floor in surroundings of the cooling system. 4. The cooling system according to claim 3, in which the docking device is configured for a thermally insulated and gas-tight connection of the cooling chamber with the evacuation container with regard to an environment of the cooling system. 5. The cooling system according to claim 1, in which an alarm device, which is configured for generating an alarm in reaction to any undesirable access to an interior of the cooling chamber, is provided for in the cooling chamber. 6. The cooling system according to claim 1, in which the protection device comprises the hood, and the external ventilation system is arrangedfor impingement of the interior of the hood with heated air. 7. The cooling system according to claim 1, in which the protection device comprises the movable partition walls, and theexternal ventilation system is arranged for impingement of the interior of the chamber with heated air. 8. The cooling system according to claim 1 in which the protection device is provided with an insulating mat with which the operator can be thermally insulated against the floor area. 9. The cooling system according to claim 1, which comprises a lifting device, which is arranged for changing an operating height of the cooling chamber or of parts of it relative to a floor in an environment of the cooling system. 10. The cooling system according to claim 9, in which the lifting device comprises at least one of a crane and a hydraulically operated carrier. 11. The cooling system according to claim 1, further comprising a shell device, which is configured for creating a system's protective atmosphere, which surrounds the cooling system. 12. A method for operating a cooling system according to claim 1, comprising the steps of: detecting an emergency state of the cooling system in which at least one of an operator and samples are exposed in the cooling chamber to operating conditions, which differ from a predetermined normal state, andchanging a state of at least one of the operator and the samples in order to expose the at least one of the operator and the samples to operating conditions, which are equivalent to the predetermined normal state. 13. The method according to claim 12, in which the step of changing the state comprises at least one of the steps of forming the wall opening in at least one of the side walls and evacuation of at least one of the operator and the samples through the wall opening from the cooling chamber,creating the local protective atmosphere in the environment of the operator in the cooling chamber with the protection device,changing an operating height of the cooling chamber or of parts of it relative to a floor in an environment of the cooling system using a lifting device, andcreating a system's protective atmosphere, which surrounds the cooling system; with a shell device. 14. The method according to claim 13, in which the forming step comprises: transporting the samples through the wall opening into evacuation container using a Dewar flask. 15. The method according to claim 13, in which the step of creating the local protective atmosphere comprises: covering the operator with the hood, or formation of the chamber in which the operator is accommodated, andimpingement of the interior of the hood or the chamber with heated air. 16. The method according to claim 13, in which the operating height of the cooling chamber is changed with at least one of a crane and a hydraulically operated carrier. 17. The method according to claim 13, in which the step of creating the system's protective atmosphere comprises: covering the cooling system with a gas-tight foil, andimpingement of the space covered by the gas-tight foil with air.
