Abstract

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.

Description

technical field [0001] The invention relates to refrigeration equipment maintenance. Background technique [0002] Air conditioning, refrigeration and other equipment with mechanical compression mechanism, the refrigerant used for refrigeration and the lubricating oil used for compressor lubrication are all circulated in a sealed pipeline system, and the lubricating oil and refrigerant have a certain Miscibility, when there is a leakage failure in the sealed piping system, the lubricating oil also leaks with the refrigerant at the same time as the refrigerant leaks, resulting in the lack of lubricating oil in the refrigeration piping system, resulting in poor lubrication of the compressor. Affect the service life of the compressor or directly cause the compressor to fail, and also reduce the cooling efficiency, especially in the automotive air-conditioning system, because the power input shaft end of the compressor is in a dynamic sealing state, and due to the relatively bad...
