  • the number of groove portions 64A is larger than the number of groove portions 64B.
  • the width of each groove portion 64A in the circumferential direction is smaller than the width of each groove portion 64B in the circumferential direction.
  • the relation of magnitude of the area expansion ratio between third inner circumferential surface 63A of upper heat transfer tube 61A and fourth inner circumferential surface 63B of lower heat transfer tube 61B is implemented by the relation of magnitude of the number of threads between groove portions 64A and groove portions 64B.
  • the non-azeotropic refrigerant mixture flows through outdoor heat exchanger 3 in order of upper flow inlet/outlet portion 3A, the plurality of upper heat transfer tubes 31A, the plurality of lower heat transfer tubes 31B, and lower flow inlet/outlet portion 3B, and then, condenses.
  • a gas-phase non-azeotropic refrigerant mixture mainly flows through upper flow inlet/outlet portion 3A and the plurality of upper heat transfer tubes 31A.
  • a liquid-phase non-azeotropic refrigerant mixture mainly flows through the plurality of lower heat transfer tubes 31B and lower flow inlet/outlet portion 3B.
  • each refrigerant When each refrigerant is in a liquid-phase state, the relation of magnitude of the density between each refrigerant and the incompatible oil varies between when each refrigerant is at a temperature of 10 °C and when each refrigerant is at a temperature of 60 °C.
  • the density of each refrigerant is higher than the density of the incompatible oil.
  • outdoor heat exchanger 6 configured as a corrugated heat exchanger includes: an upper header 65A (the third header) connected to upper flow inlet/outlet portion 6A (the third flow inlet/outlet portion); a lower header 65B (the fourth header) connected to lower flow inlet/outlet portion 6B (the second flow inlet/outlet portion); a plurality of heat transfer tubes 66 connected between upper header 65A and lower header 65B and extending in up-down direction A; and a plurality of corrugated fins 67.

  • Lower header 35B and lower header 65B are similar in configuration to lower heat transfer tube 31B and lower heat transfer tube 61B, respectively, each as the second tube portion shown in Figs. 4 , 6 and 8 .
  • the inner circumferential surface of upper heat transfer tube 61A may be higher in area expansion ratio than the inner circumferential surface of lower heat transfer tube 61B.
  • the inner circumferential surface of upper heat transfer tube 31A may be equal in area expansion ratio to the inner circumferential surface of lower heat transfer tube 31B.
  • Indoor temperature control unit 170 includes an indoor heat exchanger 171, a fan (not shown) serving to deliver indoor air to indoor heat exchanger 171, and a flow rate control valve 172 for controlling the flow rate of the second refrigerant.
  • Indoor heat exchanger 171 exchanges heat between the second refrigerant and indoor air.
  • the plurality of heat transfer plates 71 are provided with: their respective upper through holes contiguous to each other in direction B and located on the relatively upper side; and their respective lower through holes contiguous to each other in direction B and disposed below the upper through holes.
  • an upper distribution region 72A extending in direction B and contiguous to each first flow path H1 is provided inside the plurality of upper through holes of intermediate heat exchanger 7.
  • a lower distribution region 72B extending in direction B and contiguous to each first flow path H1 is provided.
