(11)All of electric heater is opened, control blower fan is run with the first setting speed.
In the present embodiment, first difference as 3 DEG C is set.First setting speed is 85%Xmax, and Xmax is that blower fan is maximum to be turned Speed.
(12)After all of electric heater operation setting time section(As after 5 minutes), according to the upper of indoor environment temperature Rise speed adjust rotation speed of fan.
The step specifically includes following step:
(12-1)After all electric heater operation setting time sections, the climbing speed of indoor environment temperature is obtained.
(12-2)If climbing speed >=the first sets rising value, control rotation speed of fan is constant;
If the second setting rising value≤setting rising values of climbing speed < first, improves rotation speed of fan to the 5th setting speed;

3rd, when the 3rd sets difference≤setting differences of △ T < second, following step is performed:
(31)An electric heater is opened, control blower fan is run with the 3rd setting speed.
In the present embodiment, the 3rd difference is set as 1 DEG C, the 3rd setting speed is 80% Xmax.
(32)After an electric heater operation setting time section(As after 5 minutes), according to the rising of indoor environment temperature Speed adjust rotation speed of fan.
The step specifically includes following step:
(32-1)After one electric heater operation setting time section, the climbing speed of indoor environment temperature is obtained.
(32-2)If climbing speed >=the first sets rising value, rotation speed of fan is reduced, for example rotation speed of fan is with 5% The decrease of speed of Xmax/5min, until climbing speed is less than the first setting rising value;
If the second setting rising value≤setting rising values of climbing speed < first, control rotation speed of fan is constant;
If climbing speed < second sets rising value, rotation speed of fan to the 9th setting speed is improved.
In the present embodiment, the 9th setting speed is 85% Xmax.
Therefore, when the 3rd sets difference≤△ T < second setting difference, open an electric heater, control blower fan with 3rd setting speed is run;After electric heater operation setting time section, the climbing speed adjustment blower fan according to indoor environment temperature Rotating speed;Both so that indoor temperature rapid increase, avoid temperature to rise again and too fast cause to waste.
4th, when the 4th sets difference≤setting differences of △ T < the 3rd, following step is performed:
(41)An electric heater is opened, control blower fan is run with the 4th setting speed.
In the present embodiment, the 4th difference is set as 0 DEG C, the 4th setting speed is 70% Xmax.
(42)After an electric heater operation setting time section(As after 5 minutes), according to the rising of indoor environment temperature Speed adjust rotation speed of fan.
The step specifically includes following step:
(42-1)After one electric heater operation setting time section, the climbing speed of indoor environment temperature is obtained.
(42-2)If climbing speed >=the first sets rising value, rotation speed of fan is reduced, for example rotation speed of fan is with 1% The decrease of speed of Xmax/5min;When △ T < the 5th set difference, by PID control rotation speed of fan so that difference △ T are 0.
If the second setting rising value≤setting rising values of climbing speed < first, control rotation speed of fan is constant;As △ T < During the 5th setting difference, by PID control rotation speed of fan so that difference △ T are 0.
If climbing speed < second sets rising value, rotation speed of fan is improved;When △ T < the 5th set difference, pass through PID control rotation speed of fan so that difference △ T are 0.
Wherein, the 4th setting difference(0℃)The setting differences of < the 5th < the 3rd sets difference(1℃).In the present embodiment, 0.2 DEG C of the setting differences of 0 < the 5th <.
Therefore, when the 4th sets difference≤△ T < the 3rd setting difference, open an electric heater, control blower fan with 4th setting speed is run;After electric heater operation setting time section, the climbing speed adjustment blower fan according to indoor environment temperature Rotating speed;Also, when △ T < the 5th set difference, by PID control rotation speed of fan, principle is simple, easy to use, applicability By force, strong robustness.
The setting speeds of first the 3rd setting speed > of setting speed >=the second setting speed > the 4th.
