<p>In a method for servicing a vehicle air-conditioning system (10) which is operated with a closed coolant circuit, the coolant in a service device using a reservoir vessel (19C, 19D, ...) for at least one of the filling media - a circuit mixture composed of coolant, compressor oil and, if appropriate, further mixture components sucked out of the air-conditioning system of the vehicle - is separated from the sucked-out circuit mixture and at least the non-coolant component of the circuit mixture is weighed, fresh or recovered coolant, compressor oil and, if appropriate, further mixture components are fed back into the circuit of the air-conditioning system of the vehicle in the necessary quantities in order to top up the compressor oil and, if appropriate, further components of the circuit mixture from at least one reservoir vessel for compressor oil and, if appropriate, one or more further component of the circuit mixture into the closed circuit of the air-conditioning system of the vehicle, the compressor oil and, if appropriate, the further components of the circuit mixture are sucked out from a film bag (21), composed at least of a film which is provided with a diffusion barrier, by recording the extraction weight and collapsing the film bag, and ambient atmosphere or some other gas flows in a non-pressurized fashion via suitable openings (23A) of the protective container into the space (23) between the outside of the film bag and the inside of a protective container (22) which surrounds the film bag.</p> |
