Abstract
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 ().
