Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioners, and in particular to a control method, device, electronic device and storage medium of an air conditioner. Background Art

[0002] At present, the defrosting method of air conditioners is reverse cycle defrosting, that is, during defrosting, the system flow is switched from heating mode to cooling mode, and the heat of the compressor and refrigerant is used to complete defrosting. However, in areas with hot summers and cold winters, the outdoor ambient temperature is low and the humidity is high in winter. The outdoor heat exchanger frosts frequently and the frost layer is relatively dense. Especially in severe frosting conditions or rainy and snowy weather, the frost and ice on the surface of the outdoor heat exchanger are more serious. Since the heat of the system itself can only melt the frost layer on the surface of the outdoor heat exchanger, the frost layer that has not been completely melted gradually forms an ice shell on the back of the outdoor heat exchanger. The formation of the ice shell not only seriously affects the heating performance of the air conditioner, but also makes the frosting worse, seriously affecting the reliability of the system. Summary of the invention

[0003] The present disclosure aims to solve one of the technical problems in the related art at least to some extent.

[0004] The first embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0005] When the air conditioner meets the defrosting conditions, turn on the heating function on the outdoor fan;

[0006] Determining an initial speed and a speed correction value corresponding to the outdoor fan according to a first outdoor ambient temperature when the defrosting condition is met;

[0007] Based on the initial rotation speed and the rotation speed correction value, the outdoor fan is controlled to rotate in the reverse direction.

[0008] A second aspect of the present disclosure provides a control device for an air conditioner, comprising:

[0011] A control module is used to control the outdoor fan to rotate in reverse based on the initial speed and the speed correction value.

[0012] The third aspect of the present disclosure provides an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor.

[0014] The control method, device, electronic device and storage medium of the air conditioner provided by the present disclosure have the following beneficial effects:

[0015] In the disclosed embodiment, when the air conditioner meets the defrosting condition, the heating function on the outdoor fan is turned on, and the initial speed and speed correction value corresponding to the outdoor fan are determined according to the first outdoor ambient temperature when the defrosting condition is met, and finally the outdoor fan is controlled to rotate in the opposite direction based on the initial speed and the speed correction value. Thus, during the low-temperature heating period, the speed of the outdoor fan in the opposite direction is controlled, so that the wind speed and the airflow temperature can be controlled, and the hot air flow pulsation defrosting is used to effectively solve the freezing problem of the outdoor heat exchanger under the severe frosting condition, and effectively improve the heating effect and system reliability of the air conditioner during the heating operation.

[0023] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0024] The following describes a control method, an apparatus, an electronic device, and a storage medium for an air conditioner according to embodiments of the present disclosure with reference to the accompanying drawings.

[0025] Figure 1 A flowchart of a method for controlling an air conditioner provided in an embodiment of the present disclosure is provided.

[0026] The embodiment of the present disclosure takes the control method of the air conditioner as an example in which the control device of the air conditioner is configured. The control device of the air conditioner can be applied to any electronic device so that the electronic device can perform the control function of the air conditioner.

[0027] like Figure 1 As shown, the control method of the air conditioner may include the following steps:

[0028] Step 101, when the air conditioner meets the defrosting conditions, turn on the heating function of the outdoor fan.

[0029] Optionally, when the pipe temperature of the outdoor heat exchanger is less than a preset threshold, it is determined that the air conditioner meets the defrosting condition. That is, when the pipe temperature of the outdoor heat exchanger is less than the fifth threshold, frost or ice will form on the surface of the outdoor heat exchanger, and defrosting is required.

[0030] Alternatively, the outdoor ambient temperature and the pipe temperature of the outdoor heat exchanger may be acquired first, and then the indoor ambient temperature may be acquired when the difference between the pipe temperature and the outdoor ambient temperature is greater than a sixth threshold.

[0031] The sixth threshold value may be 5 degrees Celsius (°C), 6°C, etc., which is not limited in the present disclosure.

[0032] Among them, the heating function of the outdoor fan can be realized by the heating device on the indoor fan rotor. The heating technology principle of the rotor is to make the rotor conductive through polymer composite materials and use resistance to generate heat. The power supply method is that the power supply disk structure at both ends of the rotor can be directly powered by AC power. In this technology, the rotor form is not limited and can be cross-flow, centrifugal, mixed flow, axial flow, or a combination of various forms of rotors to supply air.

[0033] Step 102, determining an initial speed and a speed correction value corresponding to the outdoor fan according to the first outdoor ambient temperature when the defrosting condition is met.

[0034] The first outdoor ambient temperature may be the outdoor ambient temperature corresponding to the moment when the defrosting condition is met.

[0035] In the disclosed embodiment, when the air conditioner meets the defrosting condition, the first outdoor ambient temperature can be immediately obtained, and then the initial speed and speed correction value corresponding to the outdoor fan can be determined according to the first outdoor ambient temperature when the defrosting condition is met. The lower the first outdoor ambient temperature, the higher the initial speed and the larger the speed correction. Thus, the heat can be output faster when the temperature is lower, thereby achieving the reliability of defrosting.

[0036] It should be noted that since the outdoor ambient temperature will not change significantly in a short period of time, the outdoor ambient temperature can be obtained only once when entering the defrost process to determine the initial speed and speed correction value. That is, during this defrost process, the initial speed and speed correction value will not change.

[0037] In the embodiment of the present disclosure, the initial rotation speed and the rotation speed correction value determined according to the first outdoor ambient temperature may be as shown in Table 1.

[0039] <![CDATA[The first outdoor ambient temperature T 外环1 > Initial speed R Speed ​​correction value ΔR <![CDATA[T1≤T 外环1 <T2]]> <![CDATA[R1]]> <![CDATA[ΔR1]]> <![CDATA[T3≤T 外环1 <T1]]> <![CDATA[R2]]> <![CDATA[ΔR2]]> <h2 style=";text-align:left;direction:ltr"><![CDATA[T4≤T <h2 style=";text-align:left;direction:ltr"> 外环1 <h2 style=";text-align:left;direction:ltr"> <T3]]><h2 style=";text-align:left;direction:ltr"> <![CDATA[R3]]> <![CDATA[ΔR3]]> <![CDATA[T 外环1 <T4]]> <![CDATA[R4]]> <![CDATA[ΔR4]]>

[0040] Among them, T1 is the first temperature, T2 is the second temperature, T3 is the third temperature, and T4 is the fourth temperature.

[0041] For example, the first temperature may be 0°C, 1°C, etc.; the second temperature may be 5°C, 6°C, etc.; the third temperature may be -5°C, -6°C, etc.; the fourth temperature may be -10°C, -11°C, etc.

[0042] Among them, R1 is the first speed, R2 is the second speed, R3 is the third speed, and R4 is the fourth speed. The first speed, the second speed, the third speed, and the fourth speed increase in sequence.

[0043] For example, the first rotation speed may be 150 revolutions per minute (rpm), 160 rpm, etc.; the second rotation speed may be 170 rpm, 180 rpm, etc.; the third rotation speed may be 200 rpm, 210 rpm, etc.; the fourth rotation speed may be 220 rpm, 230 rpm, etc.

[0044] ΔR1 is the first correction value, ΔR2 is the second correction value, ΔR3 is the third correction value, and ΔR4 is the fourth correction value. The first correction value, the second correction value, the third correction value, and the fourth correction value increase in sequence.

[0045] For example, the first correction value may be 20 revolutions, 25 revolutions, etc., and the second correction value may be 30 revolutions, 35 revolutions, etc.; the third correction value may be 40 revolutions, 45 revolutions, etc., and the second correction value may be 50 revolutions, 55 revolutions, etc.

[0046] Optionally, when the first outdoor ambient temperature is greater than or equal to the first temperature and less than the second temperature, the initial rotational speed is determined to be the first rotational speed and the rotational speed correction value is the first correction value.

[0047] Alternatively, when the first outdoor ambient temperature is greater than or equal to the third temperature and less than the first temperature, the initial rotation speed is determined to be the second rotation speed and the rotation speed correction value is determined to be the second correction value.

[0048] Alternatively, when the first outdoor ambient temperature is greater than or equal to the fourth temperature and less than the third temperature, the initial rotation speed is determined to be the third rotation speed and the rotation speed correction value is determined to be the third correction value.

[0049] Alternatively, when the first outdoor ambient temperature is lower than the fourth temperature, the initial rotational speed is determined to be the fourth rotational speed and the rotational speed correction value is determined to be the fourth correction value.

[0050] Step 103, based on the initial speed and the speed correction value, control the outdoor fan to rotate in the reverse direction.

[0051] Optionally, within the first period after entering the defrost mode, the outdoor fan is controlled to rotate in the reverse direction at an initial speed. After the first period, the speed of the indoor fan is adjusted based on a preset speed adjustment frequency and a speed correction value until the reverse rotation time of the outdoor fan reaches a second period.

[0052] The second duration is greater than the first duration. For example, the first duration may be 2 minutes, 3 minutes, etc., and the second duration may be 5 minutes, 6 minutes, etc.

[0053] The preset speed adjustment frequency may be adjusted once every 30 seconds, once every 20 seconds, etc. This disclosure does not limit this.

[0054] In some embodiments, after the duration of the outdoor fan's reverse rotation reaches a second duration, the heating function is turned off, and the outdoor fan is controlled to rotate forward.

[0055] For example, if the first duration is 3 minutes, the second duration is 5 minutes, the speed adjustment frequency can be adjusted every 30 seconds, the initial speed is 150rpm, and the speed correction value is 20 revolutions, then within 3 minutes, the outdoor fan is controlled to run at an initial speed of 150rpm, and after 3 minutes, the speed is increased by 20 revolutions every 30 seconds. That is, at 3 minutes and 30 seconds, the speed is 170rpm, at 4 minutes, the speed is 190rpm, at 4 minutes and 30 seconds, the speed is 210rpm, and at 5 minutes, the outdoor fan stops rotating, the heating function is turned off, and the outdoor fan is controlled to rotate forward.

[0056] In some embodiments, after controlling the outdoor fan to rotate in the forward direction, it is also determined in real time whether the indoor fan meets the defrosting condition. If the defrosting condition is met, the indoor fan is controlled to rotate in the outdoor direction. Thus, the cycle is executed.

[0057] In some embodiments, if the difference in the temperature of the outdoor heat exchanger pipe before and after reverse rotation is less than the temperature threshold for n consecutive cycles, it indicates that the air conditioner may have a fault and the defrosting effect is not good. Therefore, the reverse rotation control may not be performed from the n+1th time. The value of n may be 3 times, 4 times, etc. The temperature threshold may be 5°C, 6°C, etc.

[0058] In the disclosed embodiment, when the air conditioner meets the defrosting condition, the heating function on the outdoor fan is turned on, and the initial speed and speed correction value corresponding to the outdoor fan are determined according to the first outdoor ambient temperature when the defrosting condition is met, and finally the outdoor fan is controlled to rotate in the opposite direction based on the initial speed and the speed correction value. Thus, during the low-temperature heating period, the speed of the outdoor fan in the opposite direction is controlled, so that the wind speed and the airflow temperature can be controlled, and the hot air flow pulsation defrosting is used to effectively solve the freezing problem of the outdoor heat exchanger under the severe frosting condition, and effectively improve the heating effect and system reliability of the air conditioner during the heating operation.

[0059] Figure 2 A flow chart of a method for controlling an air conditioner provided by an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, the control method of the air conditioner may include the following steps:

[0060] Step 201, when the heating operation time of the air conditioner reaches a third time, obtain the second outdoor ambient temperature and the outdoor heat exchanger pipe temperature.

[0061] The third duration may be 30 minutes, 35 minutes, etc., which is not limited in the present disclosure.

[0062] The second outdoor ambient temperature may be the outdoor ambient temperature acquired in real time after the heating operation time of the air conditioner reaches the third time time.

[0063] The outdoor heat exchanger pipe temperature may be the pipe temperature of the outdoor heat exchanger obtained in real time after the air conditioner heating operation time reaches the third time period.

[0064] Step 202: If the time during which the second outdoor ambient temperature and the outdoor heat exchanger pipe temperature meet the first preset condition is greater than the first time threshold, it is determined that the air conditioner meets the defrosting condition.

[0065] The first duration threshold may be 3 minutes, 2 minutes, etc. This disclosure does not limit this.

[0066] In the embodiment of the present disclosure, the first preset condition may be as shown in Table 2.

[0067] Table 2

[0068]

[0069]

[0070] Among them, T1 is the first temperature, T2 is the second temperature, T3 is the third temperature, and T4 is the fourth temperature.

[0071] For example, the first temperature may be 0°C, 1°C, etc.; the second temperature may be 5°C, 6°C, etc.; the third temperature may be -5°C, -6°C, etc.; the fourth temperature may be -10°C, -11°C, etc.

[0075] The second outdoor ambient temperature is greater than or equal to the first temperature and less than the second temperature, and the outdoor heat exchanger pipe temperature is less than or equal to a first threshold value, and the first threshold value is the difference between the second outdoor ambient temperature and the first value;

[0076] The second outdoor ambient temperature is greater than or equal to the third temperature and less than the first temperature, and the outdoor heat exchanger pipe temperature is less than or equal to a second threshold value, and the second threshold value is the difference between the second outdoor ambient temperature and the second value;

[0077] The second outdoor ambient temperature is greater than or equal to the fourth temperature and less than the third temperature, and the outdoor heat exchanger pipe temperature is less than or equal to a third threshold value, and the third threshold value is the difference between the second outdoor ambient temperature and the third value;

[0078] The second outdoor ambient temperature is lower than the fourth temperature, and the outdoor heat exchanger pipe temperature is lower than or equal to a fourth threshold value, and the fourth threshold value is the difference between the second outdoor ambient temperature and the fourth value;

[0082] The specific implementation forms of steps 203 to 205 can refer to the detailed descriptions in other embodiments of the present disclosure, and will not be described in detail here.

[0083] In the disclosed embodiment, when the heating operation time of the air conditioner reaches the third time, the second outdoor environment temperature and the outdoor heat exchanger pipe temperature can be obtained. If the time for which the second outdoor environment temperature and the outdoor heat exchanger pipe temperature meet the first preset condition is greater than the first time threshold, it is determined that the air conditioner meets the defrosting condition, and then the heating function on the outdoor fan is turned on. According to the first outdoor environment temperature when the defrosting condition is met, the initial speed and speed correction value corresponding to the outdoor fan are determined, and finally, based on the initial speed and speed correction value, the outdoor fan is controlled to rotate in reverse. Therefore, it is possible to determine whether the defrosting condition is met based on the second outdoor environment temperature and the outdoor heat exchanger pipe temperature, so that the heating function can be accurately determined, and the timing of the outdoor fan's reverse rotation can be controlled, so that the freezing problem of the outdoor heat exchanger under severe frosting conditions can be more effectively solved.
