摘要

A method for the maintenance of a with a closed coolant - circulation system operated vehicle air conditioning system in which, in a first maintenance phase mixture used in the circuit of a refrigerant, compressor oil, as well as optionally further by the from of a vehicle air conditioning system in a separating stage (140) by means of a compressor (112) via a separator is filtered off with suction and in this case, by means of the separator of the refrigerant cycle mixture drawn off separately, komprimert and collected is determined as well as its amount. In a second maintenance phase, the refrigerant is - circulatory system of the vehicle air conditioning system by means of a vacuum pump (113) is substantially completely emptied. The in the second maintenance phase residual gases are pumped off by means of the compressor (112) by means of the separating stage (140) and the amount of collected in this case cold means radical is determined.
