This invention provides an air-conditioning range hood and its control method, relating to the technical field of kitchen appliances. The air-conditioning range hood includes: a
refrigeration system, a first heat exchange channel, a second heat exchange channel, an electric
refrigeration module, a first temperature detection module, and a controller. The
refrigeration system includes a condenser; the condenser of the refrigeration
system is located inside the first heat exchange channel; the second heat exchange channel is located outside the first heat exchange channel; the heat absorption part of the electric refrigeration module is located inside the first heat exchange channel, and the heat dissipation part of the electric refrigeration module is located inside the second heat exchange channel; along the
airflow direction of the first heat exchange channel, the heat absorption part is located in front of the condenser; the first temperature detection module is located inside the first heat exchange channel and is used to detect the temperature T1 inside the first heat exchange channel.
