摘要： The invention relates to a cooling unit for storing temperature-sensitive goods at a desired cooling temperature, comprising a cooling compartment (9) for storing the temperature-sensitive goods, an insulation (1) separating the cooling compartment (9) from an ambient space (10), a multi-stage cascade refrigeration system adapted to cool down the cooling compartment (9) to the desired cooling temperature and/or maintain the desired cooling temperature in the cooling compartment (9), said multi-stage cascade refrigeration system comprising at least a high-temperature refrigeration cycle (11) and a low-temperature refrigeration cycle (12), whereas said low-temperature refrigeration cycle (12) comprises a low-temperature evaporator (13) arranged to absorb heat from the cooling compartment (9), and whereas the high-temperature refrigeration cycle (11) comprises a high-temperature condenser (14) arranged to reject heat to the ambient space (10), whereas a high-temperature evaporator (3) of the high-temperature refrigeration cycle (11) is thermally coupled to a low-temperature condenser (4) of the low-temperature refrigeration cycle (12) in order to form an intercooler, whereas said high-temperature evaporator (3) and/or said low-temperature condenser (4) are/is thermally coupled to the insulation (1).
