Abstract
Disclosed is a cooling system comprising a refrigerant cycle for cycling refrigerant from at least a compressor unit for com-pressing gaseous refrigerant to a condenser unit for condensing gaseous refrigerant to liquid refrigerant, from the condenser unit to an evaporator unit for evaporating the liquid refrigerant to gaseous refrigerant, and from the evaporating unit back to the compressor unit, and a lubrication cycle having at least one lubricating refrigerant supply line for providing refrigerant as lubricant to a bearing assembly, wherein the at least one lubricating refrigerant supply line branches off from the refrigerant cycle at the condenser unit for providing refrigerant to the bearing assembly, and re-unites with the refrigerant cycle at the evaporator unit, for feeding back refrigerant from the bearing assembly to the refrigerant cycle.
