The invention relates to a cooling unit for storing temperature-sensitive goods at a desired cooling temperature, comprising a cooling compartment () for storing the temperature-sensitive goods, an insulation () separating the cooling compartment () from an ambient space (), a multi-stage cascade refrigeration system adapted to cool down the cooling compartment () to the desired cooling temperature and/or maintain the desired cooling temperature in the cooling compartment (), said multi-stage cascade refrigeration system comprising at least a high-temperature refrigeration cycle () and a low-temperature refrigeration cycle (), whereas said low-temperature refrigeration cycle () comprises a low-temperature evaporator () arranged to absorb heat from the cooling compartment (), and whereas the high-temperature refrigeration cycle () comprises a high-temperature condenser () arranged to reject heat to the ambient space (), whereas a high-temperature evaporator () of the high-temperature refrigeration cycle () is thermally coupled to a low-temperature condenser () of the low-temperature refrigeration cycle () in order to form an intercooler, whereas said high-temperature evaporator () and/or said low-temperature condenser () are/is thermally coupled to the insulation ().

Cooling unit

Portable cooling unit () for transporting temperature-sensitive goods while maintaining a desired cooling temperature, said portable cooling unit () comprising a multi-stage cascade refrigeration system () adapted to operate during transport of the portable cooling unit () and to cool down to and maintain temperatures of more than 70 K below ambient temperature, a suspension system () adapted and arranged to serve as elastic bearing for the multi-stage cascade refrigeration system () and/or for components of the multi-stage cascade refrigeration system (), a movement delimiting system () adapted and arranged to restrict movement of the multi-stage cascade refrigeration system () and/or the components of the multi-stage cascade refrigeration system (), an impact protection system () adapted and arranged to dampen collisions between the multi-stage cascade refrigeration system () and other parts of the portable cooling unit (), and/or between the components of the multi-stage cascade refrigeration system (), a lubrication system () facilitating lubrication of the components of the multi-stage cascade refrigeration system () for inclinations of at least 10° out of horizontal orientation of the portable cooling unit (), and a monitoring system () adapted to generate an alarm signal upon malfunction of the portable cooling unit ().
