Method for servicing vehicle-air conditioner by external servicing device, involves attaching oil collector by pressure side to suction side of compressor before recirculation of conditioned cooling medium in vehicle-air conditioner

摘要

The method involves attaching an oil collector (6) by pressure side to a suction side of a compressor (10) before the recirculation of the conditioned cooling medium in the vehicle-air conditioner by a valve switching of a heating coil (7). The cooling medium flows by the oil collector and is extracted from the heating coil. An independent claim is also included for a device for servicing a vehicle-air conditioner by an external servicing device.
