ABSTRACT:
A refrigerant cycle system in which the arrangement of a connecting pipe for connection between a compressor and an accumulator is improved effectively to recover oil collected in the accumulator to the compressor. The accumulator is installed to be separate from the compressor. A connecting pipe is arranged between the compressor and the accumulator to feed a refrigerant gas separated in the accumulator to the compressor. An oil recovery hole is provided at an inlet portion of the connecting pipe received in the accumulator such that it is arranged at a level higher than a highest level portion of the connecting pipe located outside of the accumulator. A second accumulator may be connected between the connecting pipe and the compressor while being directly installed at the compressor. In this case, the connecting pipe has an outlet portion connected to the second accumulator.
