Embodiment
The embodiment of the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.It should be appreciated that this
The embodiment of place description is merely to illustrate and explain the present invention embodiment, is not intended to limit the invention embodiment.
Air-conditioning is under the state that heats, because ambient temperature is too low, and humidity is high, the easy frosting of evaporator of air-conditioning, from
And air-conditioning draught fan power will increase, the embodiment of the present invention determines evaporator by judging A/C evaporator Guan Wen change
Frosting situation, so as to control the rotating speed of air conditioner fan.
Fig. 1 shows the schematic flow sheet of the control method of rotating speed of air conditioner fan according to an embodiment of the invention.Such as Fig. 1
Shown, one embodiment of the invention provides a kind of control method of rotating speed of air conditioner fan, as shown in figure 1, methods described is including as follows
Step：
101st, the scheduled time, measurement A/C evaporator Guan Wen are spaced；And
102nd, according to the A/C evaporator Guan Wen, the rotating speed of air conditioner fan is controlled.
Wherein, when air-conditioning is in and heats state, the compressor and blower fan of air-conditioning are normally run, and are spaced the scheduled time, are surveyed
A/C evaporator Guan Wen is measured, and according to the A/C evaporator Guan Wen, determines the frosting situation of evaporator tube temperature, so as to control institute
State rotating speed of air conditioner fan, it is to avoid blower fan overload causes the situation that blower fan is damaged.
In another embodiment of the invention, reach preset rotation speed and continue first when detecting the rotating speed of air conditioner fan
During preset time, A/C evaporator original tube temperature is measured, for example, the preset rotation speed is maximum speed N, when detecting the sky
Rotation speed of fan is adjusted when reaching preset rotation speed and continuing the first preset time, air-conditioning smooth running now measures A/C evaporator
Original tube temperature Ta.
In another embodiment of the invention, when the A/C evaporator Guan Wen is less than setting value, the air-conditioning is controlled
Rotation speed of fan is less than the preset rotation speed.The setting value can be set according to the difference of the model of the air-conditioning, can also
Set according to the original tube temperature.
In another embodiment of the invention, the scheduled time is spaced, A/C evaporator Guan Wen is measured, when air-conditioning evaporation
When device Guan Wen is less than or equal to critical-temperature and continues the first preset time, the rotating speed of air conditioner fan is adjusted to tract below described default
Rotating speed, the critical-temperature is the original tube temperature and the difference of coefficient, for example, the A/C evaporator Guan Wenwei Tb, work as Tb

Size order is the pipe temperature scopes of first pipe temperature scope ＞ the second pipe temperature scopes ＞ the 3rd, wherein the first pipe temperature scope correspondence is tied
Frost amount is 50%~0%, belongs to and there is a small amount of frosting, and the second pipe temperature scope correspondence frosting degree is 80%~50%, is belonged to
Frosting is serious, and the 3rd pipe temperature scope correspondence frosting degree is 100%~80%, that is, belongs to frosting very serious.Corresponding control
The rotating speed of air conditioner fan is rotating speed corresponding with the default pipe temperature scope, for example, due to the corresponding knot of three pipe temperature scopes
Frost amount is incremented by successively, then the corresponding rotating speed of three pipe temperature scopes can be to successively decrease successively, i.e., the first pipe temperature scope is corresponding
The corresponding rotating speed N3 of the corresponding pipe temperature scopes of rotating speed N2 ＞ the 3rd of rotating speed N1 ＞ the second pipe temperature scopes, and above three rotating speed is small
Rotating speed before the rotating speed of air conditioner fan is lowered.
Evaporator tube temperature is judged by above-described embodiment, so that it is determined that air-conditioning frosting situation, judges air-conditioning draught fan load
Whether aggravate, it is to avoid air-conditioning draught fan overload causes the situation that blower fan is damaged.
