Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the separation of a liquid refrigerant and a lubricant in an accumulator, and to ensure lubricant amount sent to a compressor.SOLUTION: As a refrigerant, only R32 or a mixed refrigerant containing the predetermined mass% or more of R32 is used. To a compressor 104 in an outdoor unit 100, a refrigerant mixed with a lubricant of a predetermined value or more so as to prevent two-layer separation of the liquid refrigerant and the lubricant is supplied. By using an oil return capillary 107, the lubricant separated by an oil separator 106 is returned to an accumulator 105, thereby suppressing the generation of a two-layer separation area in the accumulator. A gas refrigerant including the proper amount of the liquid refrigerant is sent from the accumulator 105 to the compressor 104, thereby supplying the lubricant to the compressor 104.SELECTED DRAWING: Figure 1
