[0002] When the existing electric heating air conditioner is turned on for heating, the wind gear is generally set to multiple fixed gears, such as high wind gear, medium wind gear, low wind gear, etc., and each gear corresponds to a different air supply volume. Usually, the high wind gear is to meet the rated capacity requirements of the air conditioner; the low wind gear is to meet the condensation requirements of the air conditioner. When the air conditioner has electric heating requirements, because the wind speed is fixed in the electric heating mode, if the ambient temperature is low or high, the air outlet temperature is prone to overcooling or overheating, resulting in poor comfort experience for consumers.

[0026] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0027] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0028] Unless otherwise stated, the term "plurality" means two or more.

[0029] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0030] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0031] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0032] The electric heating device of the existing air conditioner is generally a PTC type electric heating device, and the characteristic of this type of electric heating device is that the power decreases as the air volume decreases. Therefore, in the prior art, the speed of the fan is adjusted based on the temperature difference between the indoor ambient temperature and the set temperature. The closer the indoor ambient temperature is to the set temperature, the lower the fan speed is, that is, the lower the power of the electric heating device is.

[0033] Combination Figure 1 The air conditioner includes a refrigerant circulation system and a resistance-type electric heating device 10, and the refrigerant circulation system includes a compressor 21, an outdoor heat exchanger 22, a throttling device 23 and an indoor heat exchanger 24. When the air conditioner is cooling, cooling is performed through the refrigerant circulation system. When the air conditioner is heating, heating is performed through the resistance-type electric heating device 10, and the refrigerant circulation system is not running. That is, the resistance-type electric heating device 10 serves as the only heat source for heating. In addition, the characteristic of resistance-type electric heating is that the electric heating power is fixed and does not change with the change of air volume. Therefore, when the electric heating power is fixed, the air volume of the air conditioner and the temperature rise of the indoor environment are basically inversely proportional.

[0034] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling an electric heating device of an air conditioner, comprising:

[0035] S101, when the electric heating device of the air conditioner is started, the processor obtains the current indoor ambient temperature.

[0036] S102: The processor determines a target wind speed of the indoor fan according to the current indoor ambient temperature.

[0037] S103, the processor controls the indoor fan to execute the target wind speed.

[0038] Here, when the electric heating device starts to operate, the current indoor ambient temperature is obtained. Specifically, a temperature sensor can be set at the return air outlet of the air conditioner to detect the indoor ambient temperature. Alternatively, the air conditioner can obtain the indoor ambient temperature from a temperature sensor installed indoors.

[0039] Furthermore, based on the indoor ambient temperature, the target wind speed of the indoor fan is determined. In view of the inverse relationship between the air volume and the indoor ambient temperature rise, it can be seen that the lower the indoor ambient temperature and the larger the air volume, the lower the air temperature of the air conditioner. The higher the indoor ambient temperature and the smaller the air volume, the higher the air temperature of the air conditioner. In this way, the user will feel uncomfortable with cold air or overheating. Therefore, the correspondence between the indoor ambient temperature and the indoor fan wind speed can be established in advance, and the correspondence can be stored in a local server or cloud. It is called when in use, and the target wind speed is determined by looking up a table. In this way, the fan wind speed is controlled by the indoor ambient temperature, so that the fan of the air conditioner can run at a lower gear in a low temperature environment to increase the air temperature; in a higher temperature environment, it can run at a higher speed to prevent the air temperature from overheating. This will increase the user's demand for the comfort of the air outlet temperature.

[0040] The method for controlling the electric heating device of the air conditioner provided by the embodiment of the present disclosure is adopted. The type of the electric heating device is a resistance type, and the power of this type of electric heating device does not decay with the decrease of the fan air volume. Instead, when the electric heating power is fixed, the air volume of the air conditioner is basically inversely proportional to the temperature rise of the indoor environment. Therefore, the matching air volume can be determined based on the current indoor ambient temperature. Then, the air outlet temperature meets the requirements of the current ambient temperature working condition, ensuring the user's comfort requirements for the air outlet temperature.

[0041] Optionally, in step S102, the processor determines a target wind speed of the indoor fan according to the current indoor ambient temperature, including:

[0042] S121, the processor obtains a first relationship between the indoor fan wind speed and the ambient temperature range.

[0043] S122, the processor determines a target ambient temperature range corresponding to the current indoor ambient temperature.

[0044] S123: The processor determines a target wind speed of the indoor fan corresponding to the target ambient temperature range according to the first relationship.

[0045] Here, a first relationship between the indoor fan wind speed and the ambient temperature range is pre-stored. It is understandable that the gear settings of the indoor fan wind speed of the air conditioner are different, and the general wind speed includes three gears: high, medium and low. In addition, for some air conditioners, the wind speed includes two gears, high and low, or more than three gears. The ambient temperature ranges corresponding to wind speeds with different settings are different, that is, different air conditioners may have different first relationships. After obtaining the first relationship, the table can be looked up to obtain the target ambient temperature range corresponding to the current indoor ambient temperature. Then, based on the target ambient temperature range, the target wind speed of the indoor fan is determined. In this way, the target wind speed of the indoor fan meets the current indoor ambient temperature working conditions, so that the air outlet temperature is suitable to meet user needs.

[0046] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling an electric heating device of an air conditioner, comprising:

[0047] S101, when the electric heating device of the air conditioner is started, the processor obtains the current indoor ambient temperature.

[0048] S141, the processor obtains the power of the electric heating device and the wind speed information of the indoor fan; wherein the wind speed information includes the air volume of each wind speed.

[0049] S142, the processor determines the ambient temperature corresponding to each wind speed according to the second relationship between power, air volume and temperature rise range.

[0050] S143: The processor establishes a first relationship between the wind speed and the ambient temperature range according to the wind speed and the corresponding ambient temperature.

[0051] S121, the processor obtains a first relationship between the indoor fan wind speed and the ambient temperature range.

[0052] S122, the processor determines a target ambient temperature range corresponding to the current indoor ambient temperature.

[0053] S123: The processor determines a target wind speed of the indoor fan corresponding to the target ambient temperature range according to the first relationship.

[0054] S102: The processor determines a target wind speed of the indoor fan according to the current indoor ambient temperature.

[0055] S103, the processor controls the indoor fan to execute the target wind speed.

[0056] Here, for the air conditioner of a certain model, the power of its electric heating device and the wind speed information of the indoor fan are clear and can be directly called. Further, based on the second relationship, the temperature rise corresponding to each wind speed under the current electric heating device power is determined. Then, when the comfortable air outlet temperature is determined, the corresponding indoor ambient temperature can be calculated. Among them, the target temperature can be a fixed value or an interval value. Then, based on the wind speed and the calculated indoor ambient temperature, the first relationship between the fan wind speed and the ambient temperature interval is established.

[0057] As an example, at the low wind speed, the determined temperature rise is 20°C. The comfortable air outlet temperature is 35°C, and the corresponding indoor ambient temperature is calculated to be 15°C. In other words, when the current electric heating power and the current indoor ambient temperature are 15°C, the fan turns on the low wind speed to meet the user's air outlet needs. Understandably, the number of wind speeds is limited, so each wind speed corresponds to an ambient temperature range. As another example, as the parameters of the above example, a correspondence between the indoor ambient temperature range (-∞, 15] and the low wind speed can be established. That is, when the indoor ambient temperature is less than or equal to 15°C, the target wind speed is the low wind speed. In this way, the low wind speed can increase the air outlet temperature more than other higher wind speeds. So that the actual air outlet temperature approaches the target temperature.

[0058] Optionally, in step S142, the processor determines the ambient temperature corresponding to each wind speed according to the second relationship among power, air volume and temperature rise, including:

[0059] The processor calculates the temperature rise amplitude ΔT=Q / cm at different wind speeds.

[0060] The processor uses the difference between the target air outlet temperature and the temperature rise as the ambient temperature of the corresponding air gear.

[0061] Among them, Q is the rated power of the electric heating device; c is the specific heat capacity of air; m is the air mass corresponding to the air volume of each wind speed; ΔT is the temperature rise corresponding to each wind speed.

[0062] Here, the temperature rise of each wind speed is calculated according to the formula ΔT = Q / cm. Since the human body surface temperature is generally around 37°C, the target air outlet temperature can be set to 36°C. In addition, the air specific heat capacity c changes very little when the air conditioner is in normal atmospheric pressure and the air conditioner is in the normal operating temperature range, so it is considered a fixed constant here.

[0063] As an example, for a certain electric heating air conditioner, there are three wind speed gears (high wind gear, medium wind gear, low wind gear), its electric heating power is configured to be 4.8KW, the air specific heat capacity is c=1.003kJ / (kg*K), and the air density is ρ=1.29kg / m3. The air volume at each gear and the corresponding temperature rise are shown in Table 1 below.

[0064] Table 1

[0065] Fan gear <![CDATA[Air volume m 3 / h]]> Temperature rise ΔT upscale 600 22.3 Mid-range 500 26.7 Low Range 400 33.4

[0066] Based on the above table, it can be determined that the ambient temperature corresponding to the high gear is about 15°C, the ambient temperature corresponding to the mid-range is about 10°C, and the ambient temperature corresponding to the low gear is about 5°C.

[0067] Optionally, in step S143, the processor establishes a first relationship between the windshield and the ambient temperature range according to the windshield and the corresponding ambient temperature, including:

[0068] The processor uses multiple ambient temperatures as critical values ​​to generate multiple ambient temperature intervals that match the number of wind screens.

[0069] The processor establishes a first relationship by matching the windshield with the ambient temperature range one by one.

[0070] Among them, the larger the air volume represented by the wind gear, the larger the corresponding ambient temperature range value.

[0071] Here, the determined multiple ambient temperatures are used as critical values ​​to generate multiple interval values ​​that match the number of wind speed gears. Then, a first relationship between the wind speed gear and the ambient temperature interval is established. Take the data in Table 1 as an example for illustration. Assume that T1=5°C, T2=10°C, T3=15°C, then at (-∞, T1], it corresponds to a low wind speed. At (T1, T2], it corresponds to a medium wind speed. At (T2, ∞), it corresponds to a high wind speed. In some embodiments, the fan gear has less than three gears, that is, it only has a high gear and a low gear. Taking the data in Table 1 as an example, at (-∞, T1], it corresponds to a low wind speed. At (T2, ∞), it corresponds to a high wind speed. That is to say, when establishing the first relationship, match according to the number of wind speed gears as much as possible. In this way, the first relationship is universal and can be applied to air conditioners with a small number of wind speed gears.

[0072] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling an electric heating device of an air conditioner, comprising:

[0073] S101, when the electric heating device of the air conditioner is started, the processor obtains the current indoor ambient temperature.

[0074] S102: The processor determines a target wind speed of the indoor fan according to the current indoor ambient temperature.

[0075] S103, the processor controls the indoor fan to execute the target wind speed.

[0076] S204: When the wind speed of the indoor fan does not match the target wind speed, the processor controls the indoor fan to maintain the current operating speed.

[0077] Here, the situation where the number of wind speed gears of the air conditioner is less than the number of wind speed gears in the first relationship. As shown above, when the wind speed gear includes two gears and the indoor ambient temperature is at (T1, T2), the matching target wind speed is the medium wind speed. However, the air conditioner does not have a medium wind speed. In this case, the gear of the indoor fan is not adjusted, that is, the fan is controlled to maintain the current operating gear for air discharge. It can be understood that the indoor ambient temperature is relatively suitable at this time, neither too low nor too high, and a high gear or a low gear can be selected according to the user's usage habits. The current operating gear is generally a commonly used gear set by the user, so in this case, the current operating gear is maintained.

[0078] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling an electric heating device of an air conditioner, comprising:

[0079] S101, when the electric heating device of the air conditioner is started, the processor obtains the current indoor ambient temperature.

[0080] S102: The processor determines a target wind speed of the indoor fan according to the current indoor ambient temperature.

[0081] S103, the processor controls the indoor fan to execute the target wind speed.

[0082] S204: When the wind speed of the indoor fan does not match the target wind speed, the processor controls the indoor fan to maintain the current operating speed.

[0083] S305: The processor reacquires the target wind speed of the indoor fan.

[0084] S306: When the new target wind speed matches the indoor fan wind speed, the processor controls the indoor fan to execute the new target wind speed.

[0085] Here, after the indoor fan is controlled to maintain the current operating gear for a preset period of time, the indoor air outlet temperature may reach the target air outlet temperature. If it is reached, the electric heating device stops running. If it is not reached, the target wind speed of the indoor fan can be re-determined based on the new indoor ambient temperature. That is, it is judged again whether the conditions for adjusting the fan wind speed are met. If the new target wind speed matches the indoor fan wind speed, the fan wind speed is adjusted to run at the target wind speed. As an example, the current operating gear of the fan is a low gear. After running for a preset period of time, the indoor ambient temperature satisfies (T2, ∞), and the re-determined target wind speed is a high wind speed. The fan is adjusted to run at a high wind speed.

[0086] The embodiment of the present disclosure provides a device for controlling an electric heating device of an air conditioner, comprising an acquisition module, a determination module and a control module. The acquisition module is configured to acquire the current indoor ambient temperature when the electric heating device of the air conditioner is started and running. The determination module is configured to determine the target wind speed of the indoor fan according to the current indoor ambient temperature. The control module is configured to control the indoor fan to execute the target wind speed.

[0087] The device for controlling the electric heating device of the air conditioner provided by the embodiment of the present disclosure is a resistor type electric heating device. The power of this type of electric heating device does not decay as the air volume of the fan decreases. Instead, when the electric heating power is fixed, the air volume of the air conditioner is basically inversely proportional to the temperature rise of the indoor environment. Therefore, the matching air volume can be determined based on the current indoor ambient temperature. In this way, the air outlet temperature meets the requirements of the current ambient temperature working condition, ensuring the user's comfort requirements for the air outlet temperature.
