    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 heat medium circuit that circulates a heat medium different to the refrigerant on a heat source side. The heat medium circuit includes, for example, heat exchangers related to heat medium, use side heat exchangers, first heat medium flow switching devices and second heat medium flow switching devices that change passages of the use side heat exchangers, heat medium flow control devices that controls a heat medium amount in the corresponding use side heat exchangers. An on-off device is each provided on the upstream side of the heat medium flow control device and on the downstream side of the second heat medium flow switching device and a first backflow prevention device is each provided on the downstream side of the heat medium flow control device and on the upstream side of the first heat medium flow switching device.
