PURPOSE: A device for testing compressor for automobile, testing method of the same and method for determining abnormal condition are provided to determine whether a compressor is in normal condition or not using flow rate of air measured on an output end of the compressor. CONSTITUTION: A device includes a plurality of temperature sensors(21,23) detecting temperature of air on an air input end and an air output end of a compressor, respectively; a plurality of pressure sensors(22,24) detecting air pressure on the air input end and the air output end of the compressor, respectively; an air flow rate sensor(25) detecting flow rate of air flowing from the compressor into a compression tank; a timer(26) setting time for opening and closing a passage of air compressed by the compressor to the compression tank; an analog-digital converter(40) receiving signals from the temperature sensors, the pressure sensors, the air flow rate sensor and the timer to convert into digital signals; a processor(50) receiving the digital signal of the analog-digital converter to test operational condition of the compressor according to preset logic and to determine abnormality; and a display(61) displaying test result output by the processor.
