    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 divides an outdoor heat exchanger to form parallel heat exchangers and supplies part of refrigerant from a compressor to the parallel heat exchangers alternately to perform defrosting, performs medium-pressure defrosting in which part of the refrigerant from the compressor is decompressed and supplied to a parallel heat exchanger to be subjected to defrosting, and the refrigerant after being used for defrosting is injected into the compressor. A first flow switching unit performs switching of a connection mode of ends of the parallel heat exchangers on compressor side, where the pressure changes among high pressure, medium pressure, and low pressure according to operation contents, to one of three modes: a mode with the ends connected to the compressor discharge side, a mode with the ends connected to the compressor suction side, and a mode with the ends connected to neither the discharge nor suction side.
