    摘要： A condenser of a refrigeration cycle apparatus includes a first passage, a second passage, and a joint. The first passage connects to the compressor at a first end and is constituted of, at a second end, a first flat heat transfer tube including a plurality of passages thereof. The second passage connects to the expansion device at a first end and is constituted of, at a second end, a second flat heat transfer tube including a plurality of passages thereof. The joint joins the first flat heat transfer tube and the second flat heat transfer tube and bends a flow of the hydrofluoroolefin-based refrigerant between the first flat heat transfer tube and the second flat heat transfer tube. A length of the second passage is equal to or shorter than a length of the first passage. The joint is provided, inside thereof, with a hollow portion.

    摘要： A multi-cylinder rotary compressor includes plural compression mechanism parts. A drawing force is applied to a vane of at least one of the compression mechanism parts radially outward with respect to a drive shaft, making a pressing force pressing the vane toward a piston smaller than in other compression mechanism parts. In a normal state, a pressing force due to a gas pressure difference between a suction pressure and a discharge pressure is larger than the drawing force, and a vane front end is pressed against a rotary piston peripheral wall. When the drawing force becomes greater than the pressing force, the vane front end is moved to separate from the rotary piston peripheral wall with a space through which oil is introduced from a sealed container, and a retention mechanism retains the vane separated from the piston, and the compression mechanism part switches to an uncompressed state.

    摘要： A scroll compressor has an electric motor portion, a compression mechanism portion connected to the electric motor portion, and an oil sump for lubricating oil in a sealed container and compresses a refrigerant in the compression mechanism portion. A used refrigerant is a halogenated hydrocarbon or a hydrocarbon having a carbon double bond in the composition or is a mixture containing one of the same. A sliding surface of at least one of two components constituting a sliding portion having a relation of sliding to each other in a sealed container is structured in such a way that an iron metal or an aluminum metal is not directly exposed.
