Abstract
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.
