The heat exchange system 2 comprises a heat exchanger 21 and a fan structure. The fan structure is used to guide the gas to flow through the heat exchanger 21 and blow out to the room, so as to adjust the temperature in the room. The radiation heat exchange structure 3 is used to perform radiation heat exchange with the air in the room, so as to adjust the temperature in the room.

[0037] This application couples convection-radiation heat exchange technology with heat exchange system 2 and radiative heat exchange structure 3, and rationally optimizes the design of air conditioning structure to improve the comfort of living space and reduce air conditioning energy consumption.

[0038] This application optimizes the layout of air conditioning ducts and system control, reducing operating noise and significantly improving human comfort.
