The controller corrects the current set temperature value according to the indoor temperature, light and dark conditions, time information, indoor humidity, and wall radiation temperature, and selects the current set temperature value according to the difference between the current indoor temperature and the corrected set temperature value. The operating mode of the air conditioner.

Wherein, the operation modes of the air conditioner include: cooling mode, heating mode, dehumidification mode and air supply mode.

In this embodiment, the air conditioner further includes a second temperature sensor connected to the controller for detecting the outdoor temperature;

The controller obtains the correction value of the wall radiation to the set temperature value according to the indoor temperature and the outdoor temperature.

In this embodiment, the air conditioner further includes a key unit connected to the controller for starting the air conditioner.

Wherein, the controller is a central processing unit (Central Processing Unit, CPU) or the like.

Based on the air conditioner provided in the above embodiments, the control method of the air conditioner is as follows:

S1: Obtain a first set temperature correction value according to the indoor temperature detected by the indoor temperature sensor in the air conditioner.

Wherein, the correction value of the first set temperature is the correction value of the amount of clothing worn to the set temperature. Then this step specifically includes: determining the amount of clothing worn by the user according to the indoor temperature, and determining the first set temperature correction value according to the amount of clothing worn by the user.

For example, when the indoor temperature drops, such as in winter, the user wears thicker clothes, and the thicker the clothes, the warmer they are. Therefore, the lower the indoor temperature, the more clothes the user wears, the lower the first set temperature correction value is, and when the indoor temperature is lower than a certain threshold, the first set temperature correction value takes a negative value. Then the set temperature of the air conditioner will be lowered accordingly. The corresponding value relationship between the indoor temperature and the first preset temperature correction value can be statistically obtained based on a large amount of experimental data.

S2: Obtain the second set temperature correction value according to the current time and the light and dark state detected by the indoor photosensitive sensor in the air conditioner.

Wherein, the second set temperature correction value is a correction value of the user activity amount to the set temperature. Then this step is specifically as follows: determine whether the user is sleeping according to the time or the brightness of the light, if the user is sleeping, the activity level will decrease, and determine the second set temperature correction value according to the user activity level.

For example, at night and when the room is dark, the user is generally sleeping, so the amount of activity decreases accordingly. At this time, the required indoor setting temperature needs to be increased, and the correction value of the second setting temperature is positive and increases. . The corresponding value relationship between the time and the brightness and darkness of the light and the correction value of the second set temperature can be obtained statistically based on a large amount of experimental data.

S3: Obtain a third set temperature correction value according to the relative humidity detected by the indoor relative humidity sensor in the air conditioner.

Wherein, the third set temperature correction value is a correction value of the relative humidity to the set temperature.

For example, the greater the humidity, the hotter the user feels. The higher the relative humidity is, the lower the correction value of the third set temperature is. When the relative humidity is greater than a certain threshold, the correction value of the third set temperature is negative. Then the set temperature of the air conditioner will be lowered accordingly. The corresponding relationship between the relative humidity and the correction value of the third set temperature can be statistically obtained from a large amount of experimental data.

S4: Correct the current set temperature value according to the first set temperature correction value, the second set temperature correction value, the third set temperature correction value and the correction value of the wall radiation to the set temperature to obtain Corrected set temperature value.

Wherein, within a period of time immediately after starting up, the correction value of the wall radiation to the set temperature is 0.

It should be noted that the initial set temperature of the air conditioner is set according to the comfortable temperature felt by people in normal dressing conditions, and the initial set value is between 25°C and 28°C.

S5: Control the operation mode of the air conditioner according to the difference between the current indoor temperature and the corrected set temperature value.

Wherein, the operation modes of the air conditioner include: cooling mode, heating mode, dehumidification mode and air supply mode.

Wherein, step S4 specifically includes:

Calculate the corrected set temperature value according to formula (1):

TS'=TS+Tc+Tm+TΦ+Tr(1)

Among them, TS' is the corrected set temperature value, TS is the current set temperature value, Tc is the correction value of the amount of clothing to the set temperature, Tm is the correction value of the user's activity level to the set temperature, and TΦ is Relative humidity is the correction value of the set temperature, and Tr is the correction value of the wall radiation to the set temperature.

Wherein, the correction value Tr of the wall radiation to the set temperature is essentially the change value of the wall radiation temperature, and the formula of the change value of the wall radiation temperature disclosed in this embodiment is: Tr=A*△Ta1+B*△Ta2, wherein Tr wall The correction value of radiation to the set temperature, A and B are constant coefficients, △Ta1 is the amount of indoor temperature change (the end temperature of the indoor air temperature minus the initial temperature during the investigation time), △Ta2 is the amount of outdoor temperature change (during the investigation time The final temperature of the indoor and outdoor air temperature minus the initial temperature). The coefficients A and B are related to the material and thickness of the wall. In this embodiment, the value of A ranges from -0.98 to -0.8; the value of B ranges from -0.1 to -0.02. Obviously, when the indoor and outdoor temperatures drop, △Ta1 and △Ta2 are negative, and the calculated value of Tr is positive; when the indoor and outdoor temperature rises, △Ta1 and △Ta2 are positive, and the calculated value of Tr is negative. In this embodiment, the wall radiation temperature correction is introduced after the indoor temperature reaches the set temperature.

Wherein, step S5 specifically includes:

A01: Obtain the difference ΔT between the current indoor temperature and the corrected set temperature value;

A02: If the difference is greater than the first preset threshold, control the air conditioner to work in cooling mode;

A03: If the difference is greater than or equal to the second preset threshold and less than or equal to the first preset threshold, determine whether the indoor humidity is greater than the third preset threshold, and if the indoor humidity is greater than the third preset threshold, control the The air conditioner works in the dehumidification mode, otherwise the air conditioner is controlled to work in the air supply mode;

A04: If the difference is smaller than a second preset threshold, control the air conditioner to work in a heating mode.

For example, as shown in Table 1, the control mode of the air conditioner is selected according to Table 1.

Table 1 Correspondence between the range of △T and the operation mode

Wherein, t is preset, and t is greater than or equal to 0. It can be seen that the first preset threshold is greater than or equal to 0, the second preset threshold is less than or equal to 0, and the absolute value of the first preset threshold and the absolute value of the second preset threshold may be equal.

After the air conditioner selects the control mode according to the above steps, it operates according to this mode, and implements the detection of changes in the indoor temperature to make corresponding adjustments to the system.

Further, the method also includes the following steps:

The current indoor temperature value and the outdoor temperature value are detected every first preset time, and the correction value of the wall radiation to the set temperature value is obtained according to the indoor temperature value and the outdoor temperature value. Correspondingly, the current set temperature of the air conditioner is continuously corrected according to the correction value of the set temperature value obtained from the wall radiation, and the operating mode of the air conditioner is selected according to the corrected temperature.

For example, when the air conditioner is not turned on, the indoor temperature, outdoor temperature and wall temperature are close to the same. However, after the air conditioner is turned on, if the outdoor temperature is high and the indoor temperature is low, the wall temperature will decrease accordingly, but the wall temperature will decrease The speed is slower than that of the indoor air. Before the wall temperature is consistent with the indoor temperature, the wall is equivalent to a heat source relative to the indoor air. At this time, the set temperature can be reduced accordingly, so that the user’s wall temperature can drop to Consistent with the indoor temperature, improving user comfort. When the air conditioner is turned on for a period of time, the wall temperature in the room will be close to the indoor temperature. At this time, the total indoor load will drop, and the set temperature of the air conditioner will need to be adjusted accordingly. If the air conditioner is in cooling mode at this time, increase the setting If the air conditioner is in the heating mode at this time, the set temperature value will be lowered. Therefore, the correction value of the wall radiation to the set temperature is a positive value or 0 in the cooling mode, and a negative value or 0 in the heating mode.

This embodiment provides an air conditioner that can automatically control the operating mode of the air conditioner. After the user turns on the air conditioner with one key, there is no need to operate the air conditioner or set the temperature, and the air conditioner will automatically control the operating mode. Select and adjust the system to control the temperature of the room within the range that the user feels comfortable with. Solved the problem of not being able to see the operation interface clearly, and improved user comfort.
