    摘要: An air-conditioning apparatus uses R32, a refrigerant mixture containing R32 and HFO1234yf in which R32 has a mass percentage of 40% or higher, or a refrigerant mixture containing R32 and HFO1234ze in which R32 has a mass percentage of 15% or higher, as a heat-source refrigerant. The air-conditioning apparatus includes a low-pressure shell-structure compressor, a first flow switching valve, a heat-source-side heat exchanger, first flow control devices, and plural use-side heat exchangers connected by refrigerant pipes, forming a refrigeration cycle. The compressor includes a compression chamber within a sealed container including an opening extending between inside and outside of the sealed container. The air-conditioning apparatus can perform only a heating at the use-side heat exchangers, only a cooling at the use-side heat exchangers, and a mixed cooling and heating in a mixed fashion at the use-side heat exchangers.

    摘要: An air-conditioning apparatus includes a refrigerant circuit including a low-pressure shell structure compressor into which a refrigerant flowing through an injection pipe flows, a first heat exchanger, a second heat exchanger, a first expansion device, a refrigerant flow switching device, and a second expansion device configured to allow the refrigerant which has passed through the first expansion device and flows from the second heat exchanger to the first heat exchanger to have an intermediate pressure, the compressor, the first heat exchanger, the second heat exchanger, the first expansion device, the refrigerant flow switching device, and the second expansion device being connected by pipes to constitute the refrigerant circuit, and further includes a controller that controls an amount of refrigerant flowing through the injection pipe into a compression chamber. A part of a high-pressure refrigerant flowing from the first heat exchanger to the second heat exchanger flows through the injection pipe.
