Abstract
A cooling system includes a refrigerant cycle having a compressor unit for compressing gaseous refrigerant, a condenser unit for condensing gaseous refrigerant to liquid refrigerant, an optional economizer unit for reducing pressure of the refrigerant and partially evaporating the liquid refrigerant, and an evaporator unit for evaporating the liquid refrigerant to gaseous refrigerant. The refrigerant is cycled from the compressor unit to the condenser unit, from the condenser unit to evaporator unit, and back to the compressor unit. The compressor unit includes at least one bearing assembly and a lubrication cycle providing liquid refrigerant to lubricate the bearing assembly. The lubrication cycle has a lubricating refrigerant supply line, branched from the condenser unit or from the economizer unit to the bearing assembly, and connected to an injection device(s) for introducing lubricating refrigerant into the bearing assembly. A vapor separating unit separates gaseous lubricating refrigerant from liquid phase lubricating refrigerant.
