step 1, in an initial state, closing a window and presetting the minimum indoor temperature as TsThe indoor preset minimum temperature is TmThe intelligent temperature controller controls the power-off or heat supply of the electric heater in the near window area and the electric heater in the far window area to ensure the temperature T in the near window area1And the far window zone temperature T2Are equal to each other, wherein Ts< T1=T2 <Tm；
Step 2, window opening and ventilation, T1And T2Are all gradually reduced and T1 < T2When T iss< T1 < T2< TmWhen the intelligent temperature controller is used, the first power supply switch and the second power supply switch are controlled to be disconnected, and the electric heater in the near window area and the electric heater in the far window area are powered off to stop supplying heat;
step 3, continuous windowing, T1And T2All continue to decrease when T1 < Ts< T2< TmWhen the intelligent temperature controller controls the first power supply switch to be switched on, the electric heater in the near window area is powered on for heat supply, the second power supply switch is switched off, the electric heater in the far window area is powered off for stopping heat supply, and if T is detected, the electric heater in the far window area is powered off for heat supply1And T2Is restored to Ts< T1 < T2< TmIf the power supply switch I and the power supply switch II are controlled to be switched off by the intelligent temperature controller, the electric heater in the near window area and the electric heater in the far window area are powered off to stop supplying heat;
step 4, continuously windowing, if T is reached1And T2All continue to decrease when T1 < T2< TsAnd when the temperature controller is in a state of being switched on, the first power supply switch and the second power supply switch are controlled to be switched on by the intelligent temperature controller, and the electric heater in the near window area and the electric heater in the far window area are both powered on to supply heat, if T is detected, the temperature controller is switched on to supply heat1And T2Gradually increase when T1 < Ts< T2< TmWhen the intelligent temperature controller controls the first power supply switch to be switched on, the electric heater in the near window area is powered on to supply heat, the second power supply switch is switched off, the electric heater in the far window area is powered off to stop supplying heat, and if T is detected, the electric heater in the far window area is powered off to stop supplying heat1And T2Gradually increase when Ts< T1 < T2< TmWhen the intelligent temperature controller is used, the first power supply switch and the second power supply switch are controlled to be disconnected, and the electric heater in the near window area and the electric heater in the far window area are powered off to stop supplying heat;
step 5, continuously opening the window, if T1And T2Continue to lower, close window, T1And T2Gradually increase when T1 < Ts< T2< TmWhen the intelligent temperature controller is used, the power supply switch I is controlled to be connected, the electric heater in the near window area is electrified to supply heat, the power supply switch II is disconnected, and the electric heater in the far window area is powered off to stop supplying heat;
step 6, the window is continuously closed, T1And T2Continues to increase when Ts< T1 < T2< TmAnd when the power supply switch I and the power supply switch II are switched off, the electric heater in the near window area and the electric heater in the far window area are switched off to stop supplying heat, the temperature of the near window area and the temperature of the far window area tend to be the same, and the power supply switches are restored to the initial state.
9. The method as claimed in claim 8, wherein the controlling method comprises: in steps 1-6, when T is1 <TsAnd T2 <TsAnd when the window opening degree limiting device is controlled by the intelligent temperature controller, the maximum opening degree of the window is limited to be 0.
10. The method as claimed in claim 8, wherein the controlling method comprises: in steps 1-6, when T is1 >TsAnd T2 >TsAnd when the intelligent temperature controller controls the window opening degree limiting device to limit the maximum opening degree of the window to be 1.
