Abstract: An air-conditioning apparatus enables a user to recognize both a leakage of refrigerant and an abnormal condition when a refrigerant leakage condition and the abnormal condition have occurred. When a condition in which a leakage of refrigerant is detected and a condition in which an abnormality is detected have occurred together, the refrigerant leakage condition and the abnormal condition are displayed together on a display part. Consequently, when the condition in which the leakage of refrigerant is detected and the condition in which the abnormality is detected have occurred, the user is allowed to recognize the leakage of refrigerant and the abnormal condition at once.
