Refrigeration system for an air conditioner for the air conditioning of a motor vehicle and method for cooling charge air of a turbocharger of a motor vehicle

摘要

There is provided a refrigeration system for an air conditioning system for air conditioning of a motor vehicle having a refrigeration cycle (12), the refrigeration cycle (12) comprising a compressor (14) for conveying a refrigerant, a condenser (16) for condensing the compressor (14) coming from Refrigerant and a via an expansion valve (18) for the condenser (16) coming liquid refrigerant accessible evaporator (20) for cooling charge air of a turbocharger, comprising a liquid storage (24) for briefly supplying liquid refrigerant in the refrigeration cycle (12) in the flow direction of the refrigerant between the condenser (16) and the evaporator (20) and a gas reservoir (28) for receiving gaseous refrigerant from the refrigeration circuit (12) in the flow direction between the evaporator (20) and the compressor (14). By means of the liquid reservoir (24) can be achieved by a sudden addition of additional refrigerant in the evaporator (20) not otherwise readily deployable cooling peak at a sudden turning of the turbocharger, so that even in extreme situations a need-based cooling of charge air of a turbocharger of a motor vehicle is possible.
