As shown in FIG. 1 , an embodiment of the present disclosure provides a control method for an air conditioner, including the following steps:

S101: Obtain the first target operating temperature of the air conditioner when the air conditioner is turned on and running.

When the air conditioner is powered on and running, the air conditioner obtains the first target operating temperature of the air conditioner by looking up the prestored target temperature for operating the air conditioner. For example, the air conditioner automatically records the target temperature set by the user during the last air conditioner operation as 24°C (Celsius). The first target operating temperature when powering on.

S102: Determine a first operating frequency of the compressor corresponding to the first target operating temperature, and control the compressor to operate at the first operating frequency.

In practical applications, the air conditioner determines the first operating frequency of the compressor corresponding to the first target operating temperature, and controls the compressor to operate at the first operating frequency.

Optionally, determining the first operating frequency of the compressor corresponding to the first target operating temperature includes: obtaining the ambient temperature when the air conditioner is powered on; calculating the temperature difference between the ambient temperature and the first target operating temperature; The operating frequency corresponding to the difference is used as the first operating frequency.

When the air conditioner is turned on and running, the temperature sensor detects the current ambient temperature, and calculates the temperature difference between the ambient temperature and the first target operating temperature. Pre-establish the temperature difference between the ambient temperature and the first target operating temperature, and the first correspondence table of the operating frequency of the compressor. After calculating the temperature difference, the first correspondence table of the compressor can be determined by looking up the first correspondence table. operating frequency. Table 1 below shows an optional first correspondence table:

Table 1: The first correspondence table

温度差值(单位：℃)Temperature difference (unit: ℃)	运行频率(单位：HZ)Operating frequency (unit: HZ)
77	8080
55	6060
33	4040

In the first correspondence table, the operating frequency of the compressor is positively correlated with the temperature difference. The greater the temperature difference between the ambient temperature and the first target operating temperature, the greater the operating frequency of the compressor; conversely, the smaller the temperature difference between the ambient temperature and the first target operating temperature, the lower the operating frequency of the compressor. The initial operating frequency (first operating frequency) of the compressor is determined according to the temperature difference between the ambient temperature and the first target operating temperature, which helps to make the indoor ambient temperature reach the target operating temperature as soon as possible, improving user experience, and avoiding long-term operation of the compressor. Time high-frequency operation will cause damage to the compressor and improve the service life of the compressor.

S103: In the case of obtaining the second target operating temperature set by the user, determine the operating frequency compensation value of the compressor according to the temperature ratio between the second target operating temperature and the first target operating temperature.

In practical applications, when the air conditioner obtains the second target operating temperature set by the user, it determines the operating frequency compensation value of the compressor according to the temperature ratio between the second target operating temperature and the first target operating temperature.

During the operation of the air conditioner according to the first target operating temperature, if the user actively adjusts the target operating temperature of the air conditioner, it indicates that the current ambient temperature is not the ambient temperature that the user feels comfortable with. Therefore, the second target operating temperature set by the user is obtained. , and determine the operating frequency compensation value of the compressor according to the adjustment range of the target operating temperature, so as to compensate and adjust the current operating frequency of the compressor, so that the operation of the air conditioner is more in line with the actual air conditioning needs of the user.

Optionally, determining the operating frequency compensation value of the compressor according to the temperature ratio between the second target operating temperature and the first target operating temperature includes calculating the operating frequency compensation value according to the following formula:

Wherein, ΔF is the operating frequency compensation value, F ₁ is the first operating frequency, T ₁ is the first target operating temperature, and T ₂ is the second target operating temperature.

When the air conditioner is heating and running, T ₂ /T ₁ >1, indicating that the user thinks that the current heating temperature of the air conditioner is not enough to meet his own heating demand, so the target operating temperature of the air conditioner is increased, in order to meet the heating demand of the user, according to the target The adjustment range of the operating temperature is used to determine the operating frequency compensation value of the compressor. Generally speaking, when the air conditioner is heating, the value range of the first target operating temperature is [20°C, 30°C], and the value range of the second target operating temperature set by the user is 10°C above the first target operating temperature Therefore, the value range of T ₂ /T ₁ is (1, 1.5], and the corresponding operating frequency compensation value of the compressor is calculated by using the characteristic that the sinusoidal function increases within this range but the slope gradually decreases. On the one hand, The greater the adjustment range of the target operating temperature, the greater the operating frequency compensation value, which is conducive to the rapid increase of the ambient temperature of the air conditioner to meet the heating needs of users. Frequent damage to the compressor.

When the air conditioner is in cooling operation, T ₂ /T ₁ <1, indicating that the user thinks that the current cooling temperature of the air conditioner is not enough to meet his own cooling needs, so the target operating temperature of the air conditioner is lowered. In order to meet the cooling needs of the user, the adjustment range of the target operating temperature To determine the operating frequency compensation value of the compressor. Generally speaking, when the air conditioner is cooling, the value range of the first target operating temperature is [17°C, 27°C], and the value range of the second target operating temperature set by the user is within 10°C below the first target operating temperature Therefore, the value range of T ₂ /T ₁ is [0.4, 1), and the corresponding operating frequency compensation value of the compressor is calculated by using the characteristic that the cosine function decreases but the slope gradually increases within this range. On the one hand, the greater the adjustment range of the target operating temperature, the greater the operating frequency compensation value, which is conducive to the rapid increase of the ambient temperature of the air conditioner to meet the cooling needs of users; Extreme frequency reduction can cause damage to the compressor.

S104: Compensate the first operating frequency by using the operating frequency compensation value to obtain a second operating frequency.

In practical applications, the air conditioner uses the operating frequency compensation value to compensate the first operating frequency to obtain the second operating frequency.

Optionally, the second operating frequency is calculated according to the following formula:

F ₂ =F ₁ +ΔF

Wherein, F ₂ is the second operating frequency, F ₁ is the first operating frequency, and ΔF is the operating frequency compensation value.

S105: Control the compressor to run at the second running frequency.

After obtaining the second operating frequency of the compressor, the air conditioner controls the compressor to operate at the second operating frequency.

Using the control method for the air conditioner provided by the embodiments of the present disclosure, when the air conditioner is turned on and running, the first target operating temperature of the air conditioner is obtained, the first operating frequency of the compressor corresponding to the first target operating temperature is determined, and the compressor is controlled. Run according to the first operating frequency, in the case of obtaining the second target operating temperature set by the user, determine the operating frequency compensation value of the compressor according to the temperature ratio between the second target operating temperature and the first target operating temperature, and use the operating frequency compensation value Compensating the first operating frequency to obtain a second operating frequency, and controlling the compressor to operate at the second operating frequency. In this way, during the operation of the air conditioner, after the user adjusts the target temperature of the air conditioner according to his actual physical sensation, the operating frequency of the current air conditioner compressor is fine-tuned and compensated according to the target temperature set by the user, which can better meet the user's actual air conditioning. demand and improve user experience.

In some embodiments, the control method for the air conditioner further includes: after controlling the compressor to operate at the first operating frequency or the second operating frequency, obtaining the first body surface temperature change curve of the target user within the first preset time period; according to The first body surface temperature change curve adjusts the rotational speeds of the internal and external fans.

In practical applications, after the air conditioner controls the compressor to run at the first operating frequency or the second operating frequency, the first body surface temperature change curve of the target user within the first preset time period is obtained, and the internal and external temperature is adjusted according to the first body surface temperature change curve. The speed of the fan.

The value range of the first preset duration is [5min, 10min], for example, 5min, 7min, 9min, 10min. The first body surface temperature change curve is used to indicate the user's body surface temperature change trend over time after the air conditioner control compressor operates at the first operating frequency or the second operating frequency. The change of the user's body surface temperature can objectively reflect the change of the user's actual physiological state. For example, a faster change rate of the user's body surface temperature indicates that the body dissipates more heat, and a slower change rate of the user's body surface temperature indicates that the body dissipates less heat. Therefore, adjusting the rotation speeds of the internal and external fans according to the first body surface temperature change curve can improve the indoor environment and accelerate the heat dissipation of the user, which can better improve the comfort of the user.

Optionally, adjusting the speed of the internal and external fans according to the first body surface temperature change curve includes: determining the first maximum curvature in the first body surface temperature change curve; For the current speed of the fan, increase the speed of the internal and external fans according to the first speed increment.

The first maximum curvature in the first body surface temperature change curve is greater than the preset curvature, indicating that the user’s body surface temperature change rate is relatively large. Increase the speed of the inner and outer fans of the air conditioner according to the first speed increment, and fine-tune the speed of the inner and outer fans of the air conditioner. , so as to improve the indoor environment and enhance the user experience.

In some embodiments, the control method for the air conditioner further includes: after increasing the speed of the internal and external fans according to the first speed increment, obtaining a second body surface temperature change curve of the target user within a second preset time period; Adjust the speed of the internal and external fans according to the temperature change curve of the table.

In practical applications, after the air conditioner increases the speed of the internal and external fans according to the first speed increment, it obtains the second body surface temperature change curve of the target user within the second preset time period, and adjusts the speed of the inside and outside fans according to the second body surface temperature change curve .

The value range of the second preset duration is [8min, 15min], for example, 8min, 10min, 13min, 15min. The second body surface temperature change curve is used to indicate the change trend of the user's body surface temperature over time after the air conditioner increases the speed of the internal and external fans according to the first speed increment. According to the second body surface temperature change curve, the speed of the internal and external fans is further adjusted to improve the indoor environment and accelerate the heat dissipation of the user, which can better improve the comfort of the user.

Optionally, adjusting the speed of the internal and external fans according to the second body surface temperature change curve includes: determining the second maximum curvature in the second body surface temperature change curve; For the current speed of the fan, increase the speed of the internal and external fans according to the second speed increment; wherein, the second speed increment is smaller than the first speed increment.

Optionally, the second rotational speed increment is calculated as follows:

Wherein, Δr ₁ is the first rotational speed increment, and Δr ₂ is the second rotational speed increment.

On the one hand, after the air conditioner increases the speed of the internal and external fans according to the first speed increment, the second maximum curvature in the second body surface temperature change curve is greater than the preset curvature, indicating that the user's body surface temperature changes at a relatively large rate. Incrementally increase the speed of the internal and external fans of the air conditioner, and continue to adjust the speed of the internal and external fans of the air conditioner, thereby improving the indoor environment and enhancing the user experience; on the other hand, setting the second speed increment While adjusting the speed of the fan, avoid excessive adjustment of the speed of the internal and external fans of the air conditioner, which will not match the operating parameters such as the operating frequency of the air conditioner compressor and the flow rate of the refrigerant, causing damage to the air conditioner and reducing the service life of the air conditioner.
