The invention discloses an oil-containing refrigerant and a production process thereof and relates to maintenance of refrigeration equipment. The oil-containing refrigerant mainly comprises a pressure container and a mixture of the refrigerant and lubricating oil, and the mixture is sealed in the pressure container. As for air conditioning, refrigeration and other equipment with mechanical compression mechanisms, when leakage failure occurs, the lubricating oil can also leak along with the refrigerant, thereby causing the loss of the lubricating oil in a refrigeration pipeline system. After a repairman repairs the failure, the refrigerant has to be emptied due to the process need of supplementing and adding the lubricating oil, the inside of the refrigeration pipeline system needs to achieve a certain degree of vacuum, and then the lubricating oil can be conveniently supplemented and added, thereby causing the waste of the refrigerant and the lubricating oil and further exacerbating the environmental pollution. The invention aims at directly supplementing and adding the refrigerant and the lubricating oil without using the vacuum-pumping maintenance process flow under the situation that the refrigerant is arranged in the refrigeration pipeline system, simplifying the maintenance process, reducing the maintenance cost and further reducing the environmental pollution.
