PROBLEM TO BE SOLVED: To provide an injection method and an injection device of refrigerating machine oil for sealing, and a refrigerating device such as an air conditioner injecting the refrigerating machine oil by the injection method and the injection device, effectively sealing a part of refrigerant leakage without causing a trouble that fine particles for sealing stay at one spot in a refrigerant passage of the refrigerating device such as the air conditioner, and the refrigerant passage is blocked at injecting the refrigerating machine oil including the fine particles for sealing. SOLUTION: The refrigerating machine oil including the fine particles for sealing is injected in a mist state through a high-pressure injection pump 10 on the way of a high pressure-side refrigerant gas pipe from a compressor discharge side to a condenser inlet side of the refrigerant circulation passage at injecting the refrigerating machine oil including the fine particles for sealing to the refrigerant circulation passage of the refrigerating device such as the air conditioner.
