In order to achieve a better heat exchange effect, generally, the self rotating speeds of different fans are controlled in the air conditioner operation process, if the heat exchange is required to be accelerated, the rotating speed of the fans can be increased, or if the heat exchange is required to be slowed down, the rotating speed of the fans can be reduced. Therefore, the change of the rotating speed of the fan can be directly related to the heating or cooling performance of the air conditioner.

Fig. 1 is a flow chart illustrating a control method of the present invention according to an exemplary embodiment.
As shown in fig. 1, the present invention provides a method for controlling a rotation speed of an outdoor fan of an air conditioner, which can be used for controlling and adjusting the rotation speed of the outdoor fan when the air conditioner is started or the instantaneous pressure change of the pressure in the internal system of the air conditioner is large, and specifically, the method comprises the following steps:
s101, acquiring a first indoor temperature of an indoor area where an air conditioner is located;
in this embodiment and the following embodiments of the present invention, a split type air conditioner is taken as an example, and the split type air conditioner mainly includes an indoor unit and an outdoor unit, wherein the indoor unit is disposed in indoor areas such as a living room and a bedroom, and the outdoor unit is disposed in outdoor areas such as an outer wall and a roof of a building. The indoor unit is provided with a temperature sensor capable of sensing temperature changes in the indoor environment, so that in step S101, the indoor temperature can be detected by the temperature sensor and used as the first indoor temperature parameter of the current control process.
Generally, indoor units are respectively arranged in indoor areas such as a living room and a bedroom, each indoor unit is provided with an independent outdoor unit, namely, the common household air conditioner type is operated by one indoor unit and one outdoor unit, therefore, for an air conditioner applying the control method disclosed by the invention, the collected indoor temperature is the temperature parameter of the specific indoor area where the indoor unit is located, for example, for the indoor unit arranged in the living room, the first indoor temperature obtained in the air conditioner execution step S101 is the real-time temperature of the living room area; similarly, for the indoor unit arranged in the bedroom, the real-time temperature of the bedroom is acquired by the air conditioner.
For the application scenarios of office buildings, hotels and the like, a commercial air conditioner type with one outdoor unit connected with two or more indoor units is mostly adopted, wherein different indoor units are respectively located in different indoor areas, so that for the commercial air conditioner type, the indoor units in the starting state respectively acquire the indoor temperatures of the corresponding indoor areas through independent temperature sensors, and then the average value of the indoor temperatures is calculated through preset algorithms such as a weighting algorithm and the like and is used as a first indoor temperature parameter of the current control process.
S102, determining and controlling an outdoor fan to operate at a first outdoor unit wind speed according to a first temperature difference value between a first indoor temperature and a target indoor temperature;
in step S102, the first indoor temperature is the indoor temperature parameter obtained in step S101, and the target indoor temperature is a temperature value expected to be achieved indoors and input by the user through the remote controller or the control panel, where for the above-mentioned household air conditioner type, because it is a structural form in which one indoor unit corresponds to one outdoor unit, the target indoor temperature value in step S102 is a single set temperature value; for the above-mentioned household air conditioner type, because it is a structural form in which one outdoor unit corresponds to a plurality of indoor units, and a user may set target indoor temperatures with different values for different indoor units, the target indoor temperature may be an average value obtained by weighted calculation of the target indoor temperatures set by the plurality of indoor units in the activated state; alternatively, the air conditioner may have default target indoor temperature values for different seasons or different times of the day stored in advance, and the default target indoor temperature values may be used as the target indoor temperatures in step S102.
For example, in one embodiment, the default target indoor temperature values set by the air conditioner include, but are not limited to, 28 ℃ in summer, 20 ℃ in winter, and so forth; alternatively, default target indoor temperature values for different times of the same day in the summer include, but are not limited to, 28 ℃ at 8 points, 25 ℃ at 12 points, 24 ℃ at 15 points, and so on. Therefore, when the set target indoor temperatures received by a plurality of indoor units of the commercial air conditioner type are large in difference, the air conditioner can obtain the target indoor temperature of the control flow by checking the default target indoor temperature value preset by the system.
In one embodiment, the target indoor temperature is generally lower than the indoor temperature in the summer cooling condition; in winter heating, the target indoor temperature is generally higher than the indoor temperature. Therefore, in order to facilitate the determination of the first outdoor unit wind speed in the outdoor fan, the control flow of the present invention also determines the operation mode of the air conditioner in advance before determining and controlling the outdoor fan to operate at the first outdoor unit wind speed according to the temperature difference between the first indoor temperature and the target indoor temperature, wherein the operation mode includes a cooling mode and a heating mode.
Thus, when the operation mode is the refrigeration mode, the first temperature difference value is a first refrigeration temperature difference value obtained by subtracting the target indoor temperature from the first indoor temperature, and the second temperature difference value is a second refrigeration temperature difference value obtained by subtracting the target indoor temperature from the second indoor temperature; when the operation mode is the heating mode, the first temperature difference is a first heating temperature difference obtained by subtracting the first indoor temperature from the target indoor temperature, and the second temperature difference is a second heating temperature obtained by subtracting the second indoor temperature from the target indoor temperature.
Alternatively, in step S102, an absolute value of a temperature difference between the first indoor temperature and the target indoor temperature may be directly calculated, and the outdoor fan may be determined and controlled to operate at the first outdoor unit wind speed according to the absolute value.
Specifically, in an alternative embodiment, when the operation mode of the air conditioner is the cooling mode, the determining and controlling the outdoor fan to operate at the first outdoor unit wind speed according to the first temperature difference between the first indoor temperature and the target indoor temperature in step S102 mainly includes:
when the first refrigeration temperature difference value is larger than the first temperature difference threshold value, the wind speed of the first external unit is the high wind speed;
when the first refrigeration temperature difference value is smaller than the first temperature difference threshold value and is larger than or equal to the second temperature difference threshold value, the wind speed of the first outdoor unit is the wind speed of the wind;
and when the first refrigeration temperature difference value is smaller than the second temperature difference threshold value, the wind speed of the first outdoor unit is the low wind speed.
In this embodiment, the first temperature difference threshold and the second temperature difference threshold are both preset threshold parameters of the air conditioner, preferably, the first temperature difference threshold is 1.5-2.5 ℃, and the second temperature difference threshold is-0.5 ℃.
For the outdoor fan of the air conditioner, the maximum wind speed upper limit is provided, for example, the maximum wind speed upper limit of the outdoor fan in one embodiment is the wind speed corresponding to the rotating speed of 1500r/min, the rotating speed of the outdoor fan can be adjusted between 0 and 1500r/min, thereby changing the wind speed of the outdoor fan, the invention divides the rotating speed of the outdoor fan into a plurality of wind speed intervals according to the rotating speed in advance, for example, 1000-1500 r/min is the wind speed interval corresponding to the high wind speed, 500-1000 r/min is the wind speed interval corresponding to the medium wind speed, and 0-500 r/min is the wind speed interval corresponding to the low wind speed, thus, when the first refrigeration temperature difference value meets the judgment condition of one preset threshold parameter, the wind speed of the outdoor fan can be adjusted to the corresponding rotating speed so as to control the actually achieved wind speed of the outdoor fan to be in a matched wind speed interval.
Or, in another embodiment, the outdoor fan adopts different gear settings to perform rotation speed control and wind speed adjustment, for example, the outdoor fan includes five gears 1, 2, 3, 4, and 5, where the rotation speed gear corresponding to the low wind speed in the gear 1, the rotation speed gear corresponding to the high wind speed in the gears 2 and 3, and the rotation speed gear corresponding to the high wind speed in the gears 4 and 5. Therefore, when the first refrigeration temperature difference value meets the judgment condition of a certain preset threshold parameter, the wind speed of the outdoor fan can be adjusted to the corresponding gear, so that the actually achieved wind speed of the outdoor fan is controlled to be in a matched wind speed interval.
In another optional embodiment, when the operation mode is the heating mode, in step S102, according to a first temperature difference between the first indoor temperature and the target indoor temperature, determining and controlling the outdoor fan to operate at a first outdoor unit wind speed, which mainly includes:
when the first heating temperature difference value is larger than a first temperature difference threshold value, the wind speed of the first external unit is a high wind speed;
when the first heating temperature difference value is smaller than a first temperature difference threshold value and larger than or equal to a second temperature difference threshold value, the wind speed of the first outdoor unit is the wind speed of the wind;
and when the first heating temperature difference value is smaller than the second temperature difference threshold value, the wind speed of the first outer unit is the low wind speed.
In this embodiment, the first temperature difference threshold and the second temperature difference threshold are both preset threshold parameters of the air conditioner, preferably, the first temperature difference threshold is 1.5-2.5 ℃, and the second temperature difference threshold is-0.5 ℃.
The determination and control method of the air speed of the first external unit in the heating mode of the air conditioner may refer to the control flow in the cooling mode in the foregoing embodiment, which is not described herein again.
S103, acquiring a second indoor temperature of the indoor area and the running frequency of the compressor after a set time interval;
in this embodiment, the second indoor temperature may be obtained by referring to the step related to the first indoor temperature in step S101, which is not described herein again.
For the aforementioned one-to-one embodiment of the home air conditioner model, the current operating frequency of the air conditioner compressor is acquired in step S103.
For the embodiment of the commercial air conditioner type, the air conditioner acquires the operating frequency of each compressor in the starting state, so that the air conditioner can obtain an average value of the operating frequencies through calculation processes such as weighted calculation and the like on the operating frequencies of the plurality of compressors, and the average value is taken as an operating frequency parameter in step S103.
Generally, after the air-conditioning outdoor fan operates at the first outdoor unit wind speed for the set time interval, the pressure condition in the air-conditioning system tends to be stable, and at this time, if the air-conditioning outdoor fan still operates at the first outdoor unit wind speed, the pressure condition is not matched with the current heat exchange requirement of the air conditioner. Therefore, the second outdoor unit wind speed of the outdoor fan is calculated and determined again according to the indoor temperature obtained by secondary detection and the running frequency of the compressor, and the outdoor fan is adjusted from the first outdoor unit wind speed to the second outdoor unit wind speed, so that the wind speed of the outdoor fan can be matched with the pressure stable state under the current working condition, the additional power consumption of the air conditioner is reduced, and the overall running performance of the air conditioner is improved.
And S104, determining and controlling the outdoor fan to operate at the second external fan wind speed according to a second temperature difference value between the second indoor temperature and the target indoor temperature and the operation frequency.
In the present embodiment, the target indoor temperature is the target indoor temperature in the aforementioned step S102.
In one embodiment, when the operation mode is the cooling mode, the determining and controlling the outdoor fan to operate at the second outdoor fan speed according to the second temperature difference between the second indoor temperature and the target indoor temperature and the operation frequency in step 104 mainly includes:
when the second temperature difference value is larger than a third temperature difference threshold value, determining that the wind speed of the second external machine is the high wind speed;
when the second temperature difference value is smaller than a third temperature difference threshold value, determining the wind speed of the second external machine according to the operating frequency;
wherein, according to the operating frequency, determining the second external machine wind speed comprises:
when the operating frequency is greater than or equal to the first frequency threshold value, determining that the wind speed of the second external machine is the wind speed of the wind stroke;
and when the operating frequency is smaller than the first frequency threshold value, determining that the second external machine wind speed is a low wind speed.
In this embodiment, the third temperature difference threshold is a preset threshold parameter of the air conditioner, and preferably, the third temperature difference threshold is 1.5-2.5 ℃.
The first frequency threshold is a preset threshold parameter of the air conditioner, and preferably, the value range of the first frequency threshold is 70-80 Hz.
In another alternative embodiment, similar to the previous embodiment, when the operation mode is the heating mode, the determining and controlling the outdoor fan to operate at the second outdoor fan speed according to the second temperature difference between the second indoor temperature and the target indoor temperature and the operation frequency in step S104 specifically includes:
when the second temperature difference value is larger than the fourth temperature difference threshold value, determining that the wind speed of the second external machine is the high wind speed;
when the second temperature difference value is smaller than a fourth temperature difference threshold value, determining the wind speed of a second external machine according to the operation frequency;
wherein, according to the operating frequency, determining the second external machine wind speed comprises:
when the operating frequency is greater than or equal to a second frequency threshold value, determining that the wind speed of the second external machine is the wind speed of the wind stroke;
and when the operating frequency is smaller than a second frequency threshold value, determining that the second external machine wind speed is a low wind speed.
In this embodiment, the fourth temperature difference threshold is a preset threshold parameter of the air conditioner, and preferably, the fourth temperature difference threshold is 1.5-2.5 ℃.
The second frequency threshold is a preset threshold parameter of the air conditioner, and preferably, the value range of the first frequency threshold is 70-80 Hz.
Similarly, the rotation speed or gear of the outdoor unit corresponding to the determined second outdoor unit wind speed may refer to the rotation speed or gear setting corresponding to the first outdoor unit wind speed in step S102 in the foregoing embodiment, which is not described herein again.
In this embodiment, the set time interval is not less than 3 minutes, namely, the time length that the air conditioner outdoor fan needs to operate the first outer machine wind speed is not less than 3 minutes, so, the time of pressure buffering can be provided for the air conditioning system, and the stability of air conditioner operation is guaranteed.
