TESTING DEVICE AND METHOD FOR SERVICE LIFE OF AIR-CONDITIONING COMPRESSOR OF NEW ENERGY VEHICLE RUNNING WITH PURE GAS

Disclosed is a testing device and method for a service life of an air-conditioning compressor of a new energy vehicle running with pure gas. The testing device includes an alternative refrigeration system, a measurement and control system, and a testing environment room. A main refrigeration cycle system of the alternative refrigeration system runs with pure gas, gas of a testing compressor is discharged via a discharge throttle valve, and then enters a suction end via a suction throttle valve and an electronic expansion valve, and since there is no phase change, a heat exchange amount is small; adjustable ranges of the discharge throttle valve, the suction throttle valve and the electronic expansion valve are wide; and based on the system structure, a small refrigeration system can be used to test a compressor having high cooling capacity, and the system can quickly achieve a target working condition with a small amount of refrigerant.
