Abstract: A refrigeration cycle apparatus includes a circulation path in which a working fluid containing 1,1,2-trifluoroethylene is circulated from a compressor through a condenser, an expansion valve and an evaporator back to the compressor. The refrigeration cycle apparatus includes a composition change detection unit, a composition adjustment unit, and a control unit. The composition change detection unit detects a change of a composition of the working fluid from a steady composition thereof. The composition adjustment unit adjusts the composition of the working fluid. The control unit controls the composition adjustment unit based on a detection result obtained by the composition change detection unit.

Abstract: A compressor includes a sealed container, a compression part provided in an upper part of the inside of the sealed container and configured to compress a working medium, an oil reservoir part provided in a bottom part of the inside of the sealed container and configured to reserve a lubricating oil therein, an electric drive part provided between the compression part and the oil reservoir part inside the sealed container and configured to drive the compression part, and a power source terminal provided to pass through a wall surface of the sealed container in a region of the oil reservoir part. The power source terminal is connectable to an external power source outside the sealed container and electrically connected to the electric drive part via a lead wire in the sealed container.
