Air conditioner's compressor diagnosing device for e.g. motor vehicle, has visualization units visualizing operating state of compressor of air conditioner in cab interior of vehicle, and test loop replacing air conditioning loop

摘要

The device (1) has a test loop replacing an air conditioning loop of a vehicle, and visualization units i.e. signal lights (36, 37), visualizing an operating state of a compressor of an air conditioner in a cab interior of the vehicle. A calculating unit includes a universal serial bus (USB)outlet connected to a personal computer. The test loop has two connection tubes that connect the test loop to the compressor, and connection service valves (6, 7) connected to a refrigerant loading/unloading station that loads/unloads refrigerant i.e. 1, 1, 1, 2-tetrafluoroethane. An independent claim is also included for a method for diagnosing a compressor of an air conditioner in a cab interior of a vehicle.
