Description

Technical Field

[0001] This application relates to the field of air conditioning, and more particularly to an air conditioner and its control method, apparatus, storage medium and product. Background Technology

[0002] When an air conditioner is running in heating mode, its heating capacity is weak at the initial startup. If the indoor fan is running at the user-set fan speed, the indoor heat exchanger temperature will quickly drop below the indoor ambient temperature, causing the air conditioner to blow cold air into the room. To prevent this, air conditioners typically have an anti-cold air function. When the air conditioner enters heating mode, it adjusts the fan speed based on the indoor heat exchanger temperature. When the indoor heat exchanger temperature is low, to prevent it from dropping below the ambient temperature quickly, the air conditioner runs at a low fan speed or stops blowing air. When the indoor heat exchanger temperature is high, the air conditioner runs at the set fan speed. Once the air conditioner's heating capacity meets the mode's requirements, it returns to normal heating mode and continues operating at the set fan speed. In related technologies, the relationship between the air conditioner's fan speed and the indoor heat exchanger temperature during the initial startup phase of heating mode is as follows: Figure 1 As shown.

[0003] It should be noted that the air conditioner's anti-cold air function is triggered not only upon receiving the user's heating mode command, but also, for air conditioners with a rapid defrosting function during heating, after exiting defrost mode. Here, when the air conditioner is running in defrost mode, it diverts some of the heat from the indoor unit to the outdoor unit by controlling the opening of the expansion valve and reducing the fan speed of the indoor unit, thus eliminating the thin layer of frost covering the outdoor unit.

[0004] However, when the air conditioner is running in defrost mode, the indoor unit's fan speed is low, causing the indoor heat exchanger temperature to rise rapidly. When the air conditioner exits defrost mode and switches to heating mode, according to... Figure 1 The fan speed control method shown may cause the air conditioner to switch to the set fan speed if the indoor heat exchanger temperature is too high. At this time, the compressor and expansion valve are in the process of exiting the defrost mode. The actual heating capacity of the air conditioner does not match the fan speed, and the indoor heat exchanger temperature will drop rapidly, resulting in cold air being blown into the room. Summary of the Invention

[0005] In view of this, embodiments of this application provide an air conditioner and its control method, apparatus, storage medium and product, which aim to solve the problem of blowing cold air into the room when the air conditioner switches from defrost mode to heating mode.

[0019] After the air conditioner enters the heating mode, based on the indoor heat exchanger temperature being greater than or equal to a third temperature threshold and less than a second temperature threshold, and the current fan speed being less than or equal to the second fan speed, the air conditioner is controlled to operate at the second fan speed; and,

[0020] Based on the fact that the indoor heat exchanger temperature is greater than or equal to the second temperature threshold and less than the first temperature threshold, and the air conditioner has not been running at the second fan speed for the first set time, the air conditioner is controlled to continue running at the second fan speed.

[0021] In some implementations, the method further includes:

[0022] After exiting the defrosting mode, within a second set time period, based on the indoor heat exchanger temperature being greater than or equal to the third temperature threshold and less than the first temperature threshold, the indoor fan is controlled to increase speed at a first rate.

[0023] Based on the fact that the temperature of the indoor heat exchanger is greater than the first temperature threshold, the indoor fan is controlled to increase its speed at a second rate.

[0024] Wherein, the first rate is less than the second rate.

[0025] In some implementations, the control room fan increases speed at a first rate, including:

[0026] The first rate is determined based on the indoor heat exchanger temperature; the first rate is positively correlated with the indoor heat exchanger temperature.

[0027] Control the indoor fan to increase its speed at the first rate.

[0028] In some implementations, the method further includes:

[0029] After exiting the defrost mode, based on the indoor heat exchanger temperature being lower than the third temperature threshold and the air conditioner operating at the third fan speed, the indoor fan is controlled to stop.

[0030] Secondly, embodiments of this application provide a control device for an air conditioner, the control device comprising:

[0042] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0044] This application provides a method for controlling an air conditioner, such as... Figure 2 As shown, the method includes:

[0045] Step 201: After the air conditioner enters the heating mode, obtain the air conditioner's fan speed and the indoor heat exchanger temperature.

[0046] Step 202: Based on the indoor heat exchanger temperature being greater than or equal to a first temperature threshold, control the air conditioner to operate at a first fan speed; and based on the indoor heat exchanger temperature being greater than or equal to a second temperature threshold and the air conditioner operating at a second fan speed for a first set time, control the air conditioner to operate at a first fan speed.

[0047] Among them, the first wind speed is the wind speed set by the user; the first wind speed corresponding to the first wind speed is greater than the second wind speed corresponding to the second wind speed; and the first temperature threshold is greater than the second temperature threshold.

[0048] Here, the air conditioner in this embodiment is used to regulate the temperature, humidity, etc. of the environment. The air conditioner can be a wall-mounted air conditioner, a floor-standing air conditioner, or a window air conditioner, etc. This air conditioner is a dual-purpose air conditioner for both cooling and heating and has anti-cold air function and quick-freeze function for thin frost.

[0049] Here, if the ambient temperature of the outdoor unit of the air conditioner is low and the humidity is high, a thin layer of frost will form on the surface of the outdoor unit when the air conditioner is running in heating mode. This frost will affect the heating capacity of the air conditioner. An air conditioner with a quick-freeze frost function will enter defrost mode after detecting that the outdoor unit is covered with frost. Since there are various defrosting methods for the outdoor unit, in this embodiment, the air conditioner operates in defrost mode by controlling the opening of the expansion valve, reducing the fan speed of the indoor unit, and adjusting the compressor's operating mode to divert some of the heat from the indoor unit to the outdoor unit to eliminate the frost covering it. The air conditioner's compressor does not need to stop, and the four-way valve does not need to be reversed.

[0050] Specifically, when the air conditioner is running in defrost mode, the indoor unit's fan speed is reduced, including controlling the air conditioner to run at the third fan speed in defrost mode.

[0051] For example, the method further includes: controlling the air conditioner to enter heating mode operation in response to a heating mode command sent by the user; and controlling the air conditioner to enter heating mode operation based on exiting defrost mode operation.

[0052] It should be noted that when an air conditioner enters heating mode, the indoor heat exchanger temperature is low in the initial startup phase. If the air conditioner operates the indoor fan at the user-set fan speed, the indoor heat exchanger temperature may not provide sufficient heat, resulting in cold air being blown into the room, affecting the user experience. Therefore, air conditioners typically have an anti-cold air function to prevent cold air from being blown into the room during the initial startup phase of heating mode due to a mismatch between the air conditioner's actual heating capacity and the fan speed. After the air conditioner enters heating mode, the anti-cold air function is activated for a preset time. When the indoor heat exchanger temperature is low, the air conditioner operates at a low fan speed or stops blowing air to prevent cold air from entering the room. Once the preset time is reached, and the air conditioner's heating capacity meets the mode's requirements, the anti-cold air function is deactivated, and normal heating mode operation resumes, with the indoor fan operating at the set fan speed.

[0053] In related technologies, after the anti-cold air function is activated, the relationship between the air conditioner's fan speed and the indoor heat exchanger temperature is as follows: Figure 1 As shown, the air conditioner is set with four temperature thresholds from high to low: TEL5, TEL4, TEL3, and TEL2. The fan speed is adjusted based on the comparison between the current indoor heat exchanger temperature T2 and each temperature threshold.

[0054] Specifically, after the air conditioner activates the anti-cold air function, it includes two fan speed modes: a set fan speed and a low fan speed. If the indoor heat exchanger temperature T2 rises to the temperature threshold TEL4, the indoor fan is started and the air conditioner operates at the low fan speed. If the indoor heat exchanger temperature T2 rises to the temperature threshold TEL5, the air conditioner switches from the low fan speed to the set fan speed. If the indoor heat exchanger temperature T2 drops to the temperature threshold TEL3, the air conditioner switches from the set fan speed to the low fan speed. If the indoor heat exchanger temperature T2 drops to the temperature threshold TEL2, the indoor fan is stopped.

[0055] Understandably, when the anti-cold air function is activated, the air conditioner's fan speed is matched with the current indoor heat exchanger temperature. If the indoor fan temperature is low, the air conditioner is controlled to run at a low fan speed to avoid the air conditioner's fan speed being too high, resulting in cold air being blown.

[0056] Here, when the air conditioner is running in defrost mode, to avoid the problem of heat not being able to be distributed to the outdoor unit due to excessive fan speed, the air conditioner operates at the third fan speed, which is lower than the low fan speed. After the air conditioner exits defrost mode and enters heating mode, the anti-cold air function is triggered. The relationship between the air conditioner's fan speed and the indoor heat exchanger temperature also includes: if the indoor heat exchanger temperature T2 is greater than or equal to the temperature threshold TEL4 and less than the temperature threshold TEL5, the air conditioner is controlled to switch from the third fan speed to the low fan speed; if the indoor heat exchanger temperature T2 is greater than or equal to the temperature threshold TEL5, the air conditioner is controlled to switch from the third fan speed to the set fan speed.

[0057] However, when the air conditioner is running in defrost mode, the indoor heat exchanger temperature rises rapidly due to the lower fan speed. When the air conditioner exits defrost mode, the indoor heat exchanger temperature may still be high. If the indoor heat exchanger temperature T2 is greater than or equal to the temperature threshold TEL5, the air conditioner will directly switch from the third fan speed to the set fan speed. It should be noted that because the air conditioner's expansion valve and compressor are in the process of exiting defrost mode, the actual heating capacity of the air conditioner is weak. Since the indoor heat exchanger temperature cannot accurately reflect the actual heating capacity, if the user sets a high fan speed, the actual heating capacity of the air conditioner will not match the fan speed. In other words, every time the air conditioner exits defrost mode, even if the anti-cold air function is activated, it may still blow cold air into the room, affecting the user experience.

[0058] It should be noted that in the control method described above in the embodiments of this application, the first wind speed is the set wind speed, the second wind speed is the low wind speed, the second temperature threshold is the temperature threshold TEL5, and the third wind speed corresponding to the third wind speed is less than the second wind speed.

[0059] It should be noted that, in order to solve the aforementioned problems, the control method in this application embodiment also sets a first temperature threshold greater than the second temperature threshold. The first temperature threshold is determined based on the heating capacity of the air conditioner when it is running in defrost mode. That is, after the air conditioner exits defrost mode and enters heating mode, if the indoor heat exchanger temperature is greater than or equal to the first temperature threshold, during the period when the air conditioner's heating capacity is restored, even if it is running at the first fan speed, the indoor heat exchanger can still provide sufficient heat during the period when the heating capacity is restored. The exhaust temperature of the air conditioner is greater than the indoor ambient temperature, and there will be no problem of blowing cold air. In other words, regardless of whether the air conditioner responds to the heating mode command or exits based on the defrost mode, if the indoor heat exchanger temperature is greater than or equal to the first temperature threshold, the air conditioner will directly switch to running at the first fan speed after entering the heating mode.

[0060] In one application example of this application, the difference between the first temperature threshold and the second temperature threshold is 13°C.

[0061] It should be noted that, considering the weaker heating capacity of the air conditioner after exiting defrost mode, to avoid a mismatch between heating capacity and fan speed if the air conditioner is directly controlled to operate at the first fan speed after entering heating mode, in the control method of this application embodiment, regardless of whether the air conditioner responds to a heating mode command or exits defrost mode, if the indoor heat exchange temperature is greater than or equal to a second temperature threshold and less than a first temperature threshold, the air conditioner is controlled to operate at the second fan speed, and then switched to the first fan speed after a first set time period. Here, the first set time period is determined based on the heating capacity recovery period after the air conditioner exits defrost mode.

[0062] In one application example of this application, the first set duration is 1 minute.

[0063] It is understandable that, considering that the indoor heat exchanger temperature reflects different heating capabilities when the air conditioner is running in heating mode or defrost mode, this application embodiment sets multiple temperature ranges for the anti-cold air function to control the air conditioner's fan speed. During the period when the air conditioner exits defrost mode and resumes heating capability, the method of delaying the switching of the fan speed is used to prevent cold air from blowing into the room, thereby improving the user experience.

[0064] It should be noted that the control method in this application embodiment aims to solve the problem that the air conditioner may blow cold air into the room when switching from defrost mode to heating mode, and does not specifically limit the control method for starting and exiting defrost mode.

[0065] For example, the control method in this application embodiment further includes: after the air conditioner enters the heating mode, based on the indoor heat exchanger temperature being greater than or equal to a third temperature threshold and less than a second temperature threshold, and the current fan speed being less than or equal to a second fan speed, controlling the air conditioner to operate at a second fan speed; and based on the indoor heat exchanger temperature being greater than or equal to the second temperature threshold and less than a first temperature threshold, and the air conditioner operating at the second fan speed not reaching a first set time, controlling the air conditioner to continue operating at the second fan speed.

[0066] For example, the control method in this application embodiment further includes: after exiting the defrost mode, based on the indoor heat exchanger temperature being less than a third temperature threshold and the air conditioner operating at the third fan speed, controlling the indoor fan to stop.

[0067] Here, the third temperature threshold is temperature threshold TEL4.

[0068] Here, when the indoor fan is stopped or the air conditioner is out of defrost mode, the current fan speed of the air conditioner is less than the second fan speed; when the indoor fan is stopped, if the indoor heat exchanger temperature is less than the third temperature threshold, the indoor fan will not start and will wait for the indoor heat exchanger temperature to rise to the third temperature threshold.

[0069] For example, the control method in this application embodiment further includes: after the air conditioner enters the heating mode, based on the indoor heat exchanger temperature being greater than or equal to a fourth temperature threshold and less than a fifth temperature threshold, and the current fan speed of the air conditioner being greater than or equal to a second fan speed, controlling the air conditioner to operate at a second fan speed; and based on the indoor heat exchanger temperature being less than the fourth temperature threshold, controlling the indoor fan to stop.

[0070] Here, the fourth temperature threshold is TEL2, and the fifth temperature threshold is TEL3.

[0071] It should be noted that, in this embodiment of the application, after the air conditioner enters heating mode, the relationship between the air conditioner's fan speed and the indoor heat exchanger temperature during the activation of the anti-cold air function is as follows: Figure 3 As shown. If the air conditioner operates at the second fan speed for the first set time, then Figure 3 The shaded area shown is the area corresponding to the first fan speed setting; if the air conditioner operates at the second fan speed setting for less than the first set time, then... Figure 3 The shaded area shown is the area corresponding to the second windshield.

[0072] Here, the control method also includes: after the air conditioner enters the heating mode and runs for a third set time, controlling the air conditioner to run at the first fan speed.

[0073] Here, after the air conditioner enters heating mode and runs for a third set time, the air conditioner stops the anti-cold air function; in one application example of this application, the third set time is 5 minutes.

[0074] For example, in order to further avoid the problem of the air conditioner blowing cold air into the room after exiting the defrost mode, the control method of this application embodiment further includes: after exiting the defrost mode, within a second set time period, based on the indoor heat exchanger temperature being greater than or equal to a third temperature threshold and less than a first temperature threshold, controlling the indoor fan to increase speed at a first rate; and based on the indoor heat exchanger temperature being greater than the first temperature threshold, controlling the indoor fan to increase speed at a second rate.

[0075] The first speed is less than the second speed.

[0076] It should be noted that the air conditioner's fan speed is related to the indoor fan speed. When the air conditioner switches fan speeds, the indoor fan speed increases or decreases. After the air conditioner exits defrost mode, if the indoor heat exchanger temperature is greater than the first temperature threshold, it is determined that the indoor heat exchanger can provide sufficient heat, and the air conditioner's fan speed can quickly increase to the first fan speed. The air conditioner switches from the third fan speed to the first fan speed, and the indoor fan speeds up at the normal second speed, which is the rated speed increase rate of the indoor fan. After the air conditioner exits defrost mode, if the temperature is greater than or equal to the third temperature threshold but less than the first temperature threshold, it is determined that the actual heating capacity is weak. To avoid blowing cold air into the room, the indoor fan speeds up at a lower first speed when the air conditioner switches from the third fan speed to the second fan speed.

[0077] Here, the second set duration is less than the third set duration; in one application example of this application, the third set duration is 3 minutes.

[0078] In some embodiments, controlling the indoor fan to increase its speed at a first rate includes: determining a first rate based on the temperature of an indoor heat exchanger; the first rate being positively correlated with the temperature of the indoor heat exchanger; and controlling the indoor fan to increase its speed at the first rate.

[0079] It is understandable that the higher the temperature of the indoor heat exchanger, the more heat the indoor heat exchanger can provide in a short period of time, and the greater the initial rate.

[0080] In one application example of this application, the second rate is the indoor fan increasing its rotation speed by 8 rpm.

[0081] In one application example of this application, the first rate is shown in the following formula:

[0082] K=0.2*K0+0.8*K0*(T2-TEL4) / (TEL5-TEL4+13)

[0083] Here, K is the first rate, K0 is the second rate, and the first temperature threshold is the temperature threshold TEL5+13℃.

[0084] In another application example of this application, in conjunction with the indoor fan speed control method, the method further includes:

[0085] After exiting defrost mode, within a second set time period, based on the indoor heat exchanger temperature being greater than or equal to the fourth temperature threshold and less than the fifth temperature threshold, the indoor fan is controlled to reduce its speed at the first rate.

[0086] In this example, the first rate is shown in the following equation:

[0087] K=0.2*K0+0.8*K0*(T2-TEL2) / (TEL5-TEL2+13)

[0088] In order to implement the method of the embodiments of this application, the embodiments of this application also provide a control device for an air conditioner, which corresponds to the aforementioned control method, and the steps in the embodiments of the aforementioned control method are also fully applicable to the embodiments of this control device.

[0089] like Figure 4 As shown, the control device includes an acquisition module 401 and a control module 402. The acquisition module 401 acquires the air conditioner's fan speed and the indoor heat exchanger temperature after the air conditioner enters heating mode. The control module 402 controls the air conditioner to operate at a first fan speed based on the indoor heat exchanger temperature being greater than or equal to a first temperature threshold; and controls the air conditioner to operate at the first fan speed based on the indoor heat exchanger temperature being greater than or equal to a second temperature threshold and the air conditioner operating at a second fan speed for a first set time. The first fan speed is a user-defined fan speed; the first fan speed corresponding to the first fan speed is greater than the second fan speed corresponding to the second fan speed; and the first temperature threshold is greater than the second temperature threshold.

[0090] In some embodiments, the control module 402 is further configured to: control the air conditioner to enter heating mode operation in response to a heating mode command sent by the user; and control the air conditioner to enter heating mode operation based on exiting defrost mode operation.

[0091] In some embodiments, the control module 402 is further configured to: control the air conditioner to operate at a third fan speed in defrost mode. The third fan speed is less than the second fan speed.

[0092] In some embodiments, the control module 402 is further configured to: after the air conditioner enters the heating mode, control the air conditioner to operate at the second fan speed based on the indoor heat exchanger temperature being greater than or equal to a third temperature threshold and less than a second temperature threshold, and the current fan speed being less than or equal to a second fan speed; and control the air conditioner to continue operating at the second fan speed based on the indoor heat exchanger temperature being greater than or equal to the second temperature threshold and less than a first temperature threshold, and the air conditioner operating at the second fan speed not reaching a first set time.

[0093] In some embodiments, the control module 402 is further configured to: after exiting the defrost mode operation, within a second set time period, based on the indoor heat exchanger temperature being greater than or equal to a third temperature threshold and less than a first temperature threshold, control the indoor fan to increase its speed at a first rate; based on the indoor heat exchanger temperature being greater than the first temperature threshold, control the indoor fan to increase its speed at a second rate; wherein the first rate is less than the second rate.

[0094] In some embodiments, the control module 402 is specifically configured to: determine a first rate based on the indoor heat exchanger temperature; the first rate is positively correlated with the indoor heat exchanger temperature; and control the indoor fan to increase its speed at the first rate.

[0095] In some embodiments, the control module 402 is further configured to: after exiting the defrost mode, based on the indoor heat exchanger temperature being less than a third temperature threshold and the air conditioner operating at the third fan speed, control the indoor fan to stop.
