a convection heat exchange member disposed at an inner side of the radiation heat exchange member, configured to generate heat or cold, and to transfer the heat or cold to air flowing through the inner side of the radiation heat exchange member, and to transfer the heat or cold to an inner wall surface of the radiation heat exchange member.
4. The wall-mounted air conditioning indoor unit of claim 3, further comprising:
and the air supply fan is arranged in the shell, is positioned behind the dehumidification heat exchanger and is positioned below the radiation heat exchange piece and used for promoting the formation of air flow entering from the air inlet and exhausting from the air outlet.
5. The wall-mounted air conditioning indoor unit of claim 3, wherein the convection heat exchange member comprises:
a plurality of refrigerant channels extending along the axial direction of the radiation heat exchange piece are arranged in each heat exchange plate;
and the plurality of radiating fins are arranged on the plurality of heat exchange plates.
6. The wall-mounted air conditioning indoor unit of claim 5,
each heat exchanger plate has a first edge and a second edge extending in an axial direction of the radiant heat exchanger; the first edge is arranged in the middle of the space inside the radiation heat exchange piece, and the second edge is connected to the inner wall surface of the radiation heat exchange piece;
the heat exchange plates are uniformly distributed along the circumferential direction of the radiation heat exchange piece;
a plurality of radiating fins which are sequentially arranged along the radial direction of the radiation heat exchange piece are arranged between every two adjacent heat exchange plates;
the refrigerant channels in each heat exchange plate are sequentially arranged in the direction from the first edge to the second edge.
7. The wall-mounted air conditioning indoor unit of claim 5, further comprising:
the first electromagnetic valve is arranged at the upstream of the flow direction of a refrigerant of the dehumidification heat exchanger in refrigeration or dehumidification of the wall-mounted air conditioner indoor unit and used for controlling the flow of the refrigerant flowing into the dehumidification heat exchanger so as to enable the evaporation temperature of the refrigerant in the dehumidification heat exchanger to be lower than the dew point temperature of indoor air;
and the second electromagnetic valve is arranged at the upstream of the convection heat exchange piece in the flow direction of the refrigerant during refrigeration or dehumidification of the wall-mounted air conditioner indoor unit and controls the flow of the refrigerant flowing into the refrigerant channels, so that the evaporation temperature of the refrigerant in the refrigerant channels is higher than the dew point temperature of indoor air.
8. The wall-mounted air conditioning indoor unit of claim 3,
the convection heat exchange member defines a central channel extending in an axial direction of the radiant heat exchange member, and is located in the center of a space inside the radiant heat exchange member, and the central channel is used for circulating air.
9. The wall-mounted air conditioning indoor unit of claim 3,
the dehumidifying heat exchanger is a tube-fin evaporator or a micro-channel evaporator.
10. A wall-mounted air conditioner, comprising:
the wall-mounted air conditioning indoor unit according to any one of claims 1 to 9.
