Abstract: An oil separator includes a capturing member inside a main body container, which includes a first capturing member portion arranged on a side closer to an inflow pipe and a second capturing member portion being arranged on a side closer to an outflow pipe and having a porosity smaller than that of the first capturing member portion. Therefore, a driving force is generated by the capturing member having the different porosities. Through the driving force, a force of gravity, and a capillary phenomenon, oil inside the main body container is transported to an oil return pipe to prevent re-scattering of the oil, thereby being capable of suppressing reduction in oil separation efficiency. At the same time, oil return efficiency to the compressor is improved.

Abstract: A refrigeration cycle apparatus includes a refrigerant circuit which allows refrigerant to circulate therethrough, and an outdoor heat exchanger which exchanges heat between the refrigerant and outdoor air. The outdoor heat exchanger has first to third heat exchange sections. The second heat exchange section is located below the first heat exchange section, and the third heat exchange section is located below the second heat exchange section. In a refrigerant passage connecting the second and third heat exchange sections, a first pressure reducing device reduces a pressure of the refrigerant flowing through the refrigerant passage. In an operation mode in which the first and second heat exchange sections each serve as an evaporator, the third heat exchange section is located upstream of the second heat exchange section in the flow of the refrigerant, and refrigerant having a temperature higher than that of the outdoor air flows through the third heat exchange section.
