Definitions

  • the heating operation In the heating operation, the refrigerant sucked into the compressor 6 is compressed by the compressor 6 and discharged in a high temperature and high pressure gas state.
  • the high-temperature and high-pressure gas-state refrigerant discharged from the compressor 6 passes through the flow path switching device 7 and flows into the indoor heat exchanger 11 acting as a condenser, and in the indoor heat exchanger 11, the indoor blower. It exchanges heat with the indoor air sent by No. 12, condenses and liquefies. At this time, the indoor air is warmed and heating is performed in the room.
  • the upstream end of the fin 30 in addition to the upstream end of the flat tube 20 being at the same position as the upstream end of the fin 30, the upstream end of the fin 30 has an opening 50. A hole 34 is formed. As a result, the strength of the fin 30 can be ensured while balancing the amount of heat exchange on the upstream side and the amount of heat exchange on the downstream side of the fin 30.
  • a plurality of reinforcing portions 434 for reinforcing the fin 430 are formed at the upstream end portion of the inclined surface 30a of the fin 430.
  • the reinforcing portion 434 is obtained by bending the fin 430 into a rectangular shape and an uneven shape. Further, the upstream end of the fin 430 protrudes from the upstream end of the flat tube 20.
