<p>A method of detecting defects of a refrigerant pipe of a refrigerator having two rooms is provided to prevent defects of products by detecting temperature changes of the two rooms, and detecting reverse assembling or closure defect of the refrigerant pipe caused by mistakes of an operator. A method of detecting defects of a refrigerant pipe of a refrigerator having two rooms includes the steps of measuring initial temperatures of a room 1 and a room 2, and operating the room 1 and measuring the temperature after five minutes, thereby measuring a temperature change DeltaT1 of the room 1 and a temperature change DeltaT2 of the room 2(S201), proceeding to a step S203 for measuring the temperature change DeltaT1 of the room 1 and the temperature change DeltaT2 of the room 2 by operating the room 2 when the temperature change DeltaT1 of the room 1 is present and the temperature change DeltaT2 of the room 2 is absent after the step S201, and outputting an error state of the room 1 in the cases other than the case when the temperature change DeltaT1 of the room 1 is present and the temperature change DeltaT2 of the room 2 is absent(S202), measuring initial temperatures of the room 1 and the room 2 after the step(S202), and operating the room 2 and measuring the temperature after five minutes, thereby measuring a temperature change DeltaT1 of the room 1 and a temperature change DeltaT2 of the room 2(S203), proceeding to a termination step when the temperature change DeltaT2 of the room 2 is present and the temperature change DeltaT1 of the room 1 is absent after the step(S203), and outputting an error state of the room 2 in the cases other than the case when the temperature change DeltaT2 of the room 2 is present and the temperature change DeltaT1 of the room 1 is absent(S202) and then proceeding to the termination step(S204).</p> |
