Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically providing a heating control method for an air conditioning system and an air conditioner. Background Technology

[0002] As people's living standards improve, air conditioners have become an indispensable appliance in people's lives.

[0003] However, the installation height of indoor units in air conditioning units varies. Some indoor units are installed at a relatively high height, and the air outlet temperature is generally higher when heating. However, as the downward blowing distance increases, the temperature drops due to heat exchange between the hot air and the air, resulting in a lower temperature that reaches the human body, making users feel uncomfortable and resulting in a poor user experience.

[0004] Therefore, the present invention needs to provide a new heating control method for an air conditioning system and an air conditioner to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to address the issue that the installation height of indoor units in existing air conditioning units varies, and some indoor units are installed at a relatively high height. When heating, the air outlet temperature is generally high, but as the downward blowing distance increases, the temperature drops due to heat exchange between the hot air and the air, resulting in a lower temperature blowing onto the human body, causing discomfort to the user and a poor user experience.

[0006] To this end, in a first aspect, the present invention provides a heating control method for an air conditioning system, the air conditioning system including an indoor unit, wherein an electric heater and a fan are installed in the indoor unit, and the heating control method includes:

[0007] Obtain the installation height of the indoor unit from the ground;

[0008] Based on the installation height of the indoor unit from the ground, the electric heater and the fan can be selectively controlled to enter different operating modes.

[0009] With the above technical solution, the present invention can adjust the working mode of the electric heater and the fan according to the installation height of the indoor unit from the ground. When the air conditioning system is in heating mode, it plays an auxiliary heating role, ensuring that the temperature of the hot air blown out from the air outlet after heat exchange with the air and then blown onto the human body is still within the comfortable temperature range that the human body can accept. This makes the hot air feel comfortable when it blows onto the human body, and will not make the human body feel cold or chilly due to the temperature drop, thus improving the user experience.

[0010] In a specific implementation of the heating control method for the aforementioned air conditioning system, the step of "selectively controlling the electric heater and the fan to enter different operating modes based on the installation height of the indoor unit from the ground" further includes:

[0011] Compare the installation height with the first preset height;

[0012] If the installation height is less than the first preset height, then the electric heater and the fan are controlled to be in the user-defined default state; and / or

[0013] If the installation height is greater than the first preset height, then obtain the current indoor ambient temperature;

[0014] Based on the installation height and the indoor ambient temperature, the electric heater and the fan are selectively controlled to enter different operating modes.

[0015] When the installation height is less than the first preset height, it means that the indoor unit is relatively close to the ground. The heat exchange time between the indoor unit and the surrounding air is short during the airflow towards the human body, resulting in a slower temperature drop. Therefore, the airflow will not cause a feeling of coolness or coldness due to excessive temperature drop. The default settings can be followed. However, when the installation height is greater than the first preset height, the heat exchange path between the indoor unit and the surrounding air is longer during the airflow towards the human body. Therefore, it is necessary to detect the ambient temperature and control the operating mode of the electric heater and fan based on the installation height and the ambient temperature to achieve auxiliary heating.

[0016] In a specific implementation of the heating control method for the aforementioned air conditioning system, the step of "selectively controlling the electric heater and the fan to enter different operating modes based on the installation height and the indoor ambient temperature" further includes:

[0017] Compare the installation height with the second preset height;

[0018] If the installation height is less than the second preset height, then compare the indoor ambient temperature with the first preset temperature;

[0019] Based on the comparison between the indoor ambient temperature and the first preset temperature, the electric heater and the fan are selectively controlled to enter different operating modes; and / or

[0020] If the installation height is greater than the second preset height, then compare the indoor ambient temperature with the second preset temperature;

[0021] Based on the comparison between the indoor ambient temperature and the second preset temperature, the electric heater and the fan are selectively controlled to enter different working modes;

[0022] The second preset height is greater than the first preset height, and the second preset temperature is greater than the first preset temperature.

[0023] When the above technical solution is adopted, if the installation height of the indoor unit is less than the second preset height, it indicates that the installation height is relatively high. In this case, the working mode of the electric heater and fan is controlled according to whether the indoor ambient temperature is higher than the first preset temperature. When the installation height is greater than the second preset height, it indicates that the installation height is very high. In this case, the working mode of the electric heater and fan needs to be controlled according to whether the indoor ambient temperature is higher than the second preset temperature. Since the higher the installation height, the longer the heat exchange path and the longer the heat exchange time, the second preset temperature is higher than the first preset temperature, thus ensuring that the temperature of the hot air blown to the human body is comfortable and improving the user experience.

[0024] In a specific implementation of the heating control method for the aforementioned air conditioning system, the step of "selectively controlling the electric heater and the fan to enter different operating modes based on the comparison result between the indoor ambient temperature and the first preset temperature" specifically includes:

[0025] If the indoor ambient temperature is lower than the first preset temperature, then the electric heater is controlled to be turned on and the fan speed is controlled to be at its maximum; and / or

[0026] If the indoor ambient temperature is greater than the first preset temperature, the fan speed is controlled to be at its highest level, and the electric heater is in the user-set default state.

[0027] When the above technical solution is adopted, if the indoor ambient temperature is lower than the first preset temperature, it indicates that the indoor temperature is low. The temperature drops significantly after the hot air exchanges heat with the air during the process of blowing towards the human body, making the human body feel uncomfortable. Therefore, in this case, the electric heater is turned on to increase the temperature of the hot air blown out from the air outlet, and the fan speed is maximized. This not only improves the heat exchange efficiency, but also speeds up the blowing of hot air towards the human body, shortens the heat exchange time, and ensures the temperature of the hot air blown towards the human body. When the indoor ambient temperature is higher than the first preset temperature, it indicates that the indoor temperature is not very low. The temperature drops relatively little after the hot air exchanges heat with the air during the process of blowing towards the human body. In this case, it is sufficient to simply adjust the fan speed to the maximum.

[0028] In a specific implementation of the heating control method for the aforementioned air conditioning system, the step of "selectively controlling the electric heater and the fan to enter different operating modes based on the comparison result between the indoor ambient temperature and the second preset temperature" specifically includes:

[0029] If the indoor ambient temperature is lower than the second preset temperature, then the electric heater is controlled to be turned on and the fan speed is controlled to be at its maximum; and / or

[0030] If the indoor ambient temperature is greater than the second preset temperature, the fan speed is controlled to be at its highest setting, and the electric heater is controlled to be in the user-set default state.

[0031] In a specific embodiment of the heating control method for the above-mentioned air conditioning system, the heating control method further includes:

[0032] When the installation height is greater than the first preset height, the electric heater is turned on, and the fan speed is at its highest, the indoor ambient temperature is compared with the third preset temperature.

[0033] If the indoor ambient temperature is greater than the third preset temperature, the electric heater is controlled to be in the off state;

[0034] The third preset temperature is greater than the first preset temperature and the second preset temperature.

[0035] In a specific embodiment of the heating control method for the above-mentioned air conditioning system, the heating control method further includes:

[0036] When the installation height is greater than the first preset height and less than the second preset height, the electric heater is turned on, and the fan speed is at its highest, the indoor ambient temperature is compared with the fourth preset temperature.

[0037] If the indoor ambient temperature is greater than the fourth preset temperature, then the electric heater is controlled to be turned off, and the fan speed is controlled to return to the user-set default state; and / or

[0038] When the installation height is greater than the second preset height, the electric heater is turned on, and the fan speed is at its highest, compare the indoor ambient temperature with the fifth preset temperature.

[0039] If the indoor ambient temperature is greater than the fifth preset temperature, the electric heater is controlled to be in the off state;

[0040] Among them, the fifth preset temperature is greater than the fourth preset temperature, and the fourth preset temperature is greater than the first preset temperature and the second preset temperature.

[0041] In a specific implementation of the heating control method of the above-mentioned air conditioning system, when the electric heater has at least two settings, the electric heater is at the highest setting when the installation height is greater than the first preset height and the electric heater is in the on state.

[0042] In a specific embodiment of the heating control method for the above-mentioned air conditioning system, the step of "obtaining the installation height of the indoor unit from the ground" further includes installing a distance measuring sensor in the indoor unit:

[0043] The installation height of the indoor unit from the ground is obtained based on the distance information detected by the distance sensor.

[0044] In a second aspect, the present invention also provides an air conditioner, including a controller configured to perform the heating control method of the air conditioning system described in any of the above technical solutions. Attached Figure Description

[0049] Figure 4 This is a detailed flowchart of another embodiment of step S24. Detailed Implementation

[0050] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0051] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the relevant devices or elements must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] The installation height of indoor units in existing air conditioning units varies. Some indoor units are installed at a relatively high height, and the air outlet temperature is generally higher when heating. However, as the downward blowing distance increases, the temperature drops due to heat exchange between the hot air and the air, resulting in a lower temperature that reaches the human body, making users feel uncomfortable and resulting in a poor user experience.

[0054] To solve the above-mentioned technical problems, the present invention provides an air conditioning system, which includes an indoor unit, in which an electric heater and a fan are installed.

[0055] Additionally, first refer to Figure 1 The present invention also provides a heating control method for an air conditioning system, the heating control method comprising:

[0056] S1, obtain the installation height of the indoor unit from the ground;

[0057] S2 selectively controls the electric heater and fan to enter different operating modes based on the installation height of the indoor unit from the ground.

[0058] It should be noted that in the above steps, "ground" refers to the indoor ground where people walk, such as the floor of a building.

[0059] In one embodiment, see Figure 2 Step S2, which involves "selectively controlling the electric heater and fan to enter different operating modes based on the installation height of the indoor unit from the ground," further includes:

[0060] S21, compare the installation height with the first preset height;

[0061] S22, if the installation height is less than the first preset height, control the electric heater and fan to be in the user-set default state;

[0062] In the above steps, if the installation height is less than the first preset height, it means that the distance between the indoor unit and the ground is relatively short. The heat exchange time between the indoor unit and the surrounding air is short during the process of blowing towards the human body, and the temperature drops slowly. Therefore, when the air blows onto the human body, it will not cause a feeling of coolness or coldness due to excessive temperature drop. So just follow the default state set by the user.

[0063] S23, if the installation height is greater than the first preset height, then obtain the current indoor ambient temperature;

[0064] S24 selectively controls the electric heater and fan to enter different operating modes based on the installation height and indoor ambient temperature.

[0065] In the above steps, when the installation height is greater than the first preset height, the heat exchange path between the electric heater and the surrounding air is longer and the heat exchange time is longer when the air is blown towards the human body. Therefore, it is necessary to detect the ambient temperature and control the working mode of the electric heater and the fan according to the installation height and the indoor ambient temperature to achieve the purpose of auxiliary heating.

[0066] In one embodiment, see Figure 3 Step S24, "selectively controlling the electric heater and fan to enter different operating modes based on the installation height and indoor ambient temperature," further includes:

[0067] S241, compare the installation height with the second preset height;

[0068] S242, if the installation height is less than the second preset height, compare the indoor ambient temperature with the first preset temperature;

[0069] S243, based on the comparison between the indoor ambient temperature and the first preset temperature, selectively controls the electric heater and fan to enter different working modes;

[0070] In the above steps, if the installation height of the indoor unit is less than the second preset height, it means that the installation height is too high. At this time, the working mode of the electric heater and the fan is controlled according to whether the indoor ambient temperature is greater than the first preset temperature, so as to ensure reasonable auxiliary heating of the electric heater and the fan.

[0071] S244, if the installation height is greater than the second preset height, compare the indoor ambient temperature with the second preset temperature;

[0072] S245, based on the comparison between the indoor ambient temperature and the second preset temperature, selectively controls the electric heater and fan to enter different working modes;

[0073] The second preset height is greater than the first preset height, and the second preset temperature is greater than the first preset temperature.

[0074] In the above steps, if the installation height is greater than the second preset height, it means that the installation height is very high. At this time, it is necessary to control the working mode of the electric heater and the fan according to whether the indoor ambient temperature is greater than the second preset temperature. Since the higher the installation height, the longer the heat exchange path and the longer the heat exchange time, the second preset temperature is greater than the first preset temperature, thus ensuring that the temperature of the hot air blown on the human body is comfortable and helps to improve the experience.

[0075] In one embodiment, see Figure 3 The step S243, "selectively controlling the electric heater and fan to enter different operating modes based on the comparison between the indoor ambient temperature and the first preset temperature," specifically includes:

[0076] S2431, if the indoor ambient temperature is lower than the first preset temperature, control the electric heater to be on and control the fan speed to be at its highest.

[0077] In the above steps, if the indoor ambient temperature is lower than the first preset temperature, it means that the indoor temperature is low. The temperature drops significantly after the hot air exchanges heat with the air during the process of blowing towards the human body, making the human body feel uncomfortable. Therefore, in this case, the electric heater is turned on to increase the temperature of the hot air blown out from the air outlet. In addition, the fan speed is set to the highest level, which not only improves the heat exchange efficiency, but also speeds up the blowing of hot air towards the human body, shortens the heat exchange time, and ensures the temperature of the hot air blown towards the human body.

[0078] S2432, if the indoor ambient temperature is higher than the first preset temperature, the fan speed is controlled to be at its highest level, and the electric heater is in the user-set default state.

[0079] In the above steps, if the indoor ambient temperature is higher than the first preset temperature, it means that the indoor temperature is not very low. The temperature drop is relatively small after the hot air exchanges heat with the air during the process of blowing towards the human body. At this time, you only need to adjust the fan speed to the maximum.

[0080] In one embodiment, see Figure 3 The step S245, "selectively controlling the electric heater and fan to enter different operating modes based on the comparison between the indoor ambient temperature and the second preset temperature," specifically includes:

[0081] S2451, if the indoor ambient temperature is lower than the second preset temperature, the electric heater is turned on and the fan speed is set to the highest level.

[0082] In the above steps, when the installation height is greater than the second preset height, it means that the indoor unit is installed at a high position. In this case, the path of the hot air blowing to the human body is extended, and the heat exchange time is extended. If the temperature is still the first preset temperature, the temperature of the hot air blowing to the human body will drop more. Therefore, it is necessary to use whether the indoor temperature is greater than the second preset temperature as a judgment condition. This helps to ensure that the hot air blowing to the human body is comfortable and the user experience is good.

[0083] S2452, if the indoor ambient temperature is greater than the second preset temperature, the fan speed is controlled to be at its highest level, and the electric heater is controlled to be in the user-set default state.

[0084] In the above steps, if the indoor ambient temperature is greater than the second preset temperature, it means that the indoor ambient temperature is not low. The temperature drop is relatively small after the hot air exchanges heat with the air during the process of blowing towards the human body. At this time, you only need to adjust the fan speed to the maximum.

[0085] In one embodiment, see Figure 3 Heating control methods also include:

[0086] S3, when the installation height is greater than the first preset height, the electric heater is on, and the fan speed is at its highest, compare the indoor ambient temperature with the third preset temperature.

[0087] S4, If the indoor ambient temperature is higher than the third preset temperature, the electric heater will be turned off.

[0088] The third preset temperature is greater than the first preset temperature and the second preset temperature.

[0089] In the above steps, if the indoor ambient temperature is higher than the third preset temperature when the electric heater is turned on and the fan speed is set to the highest to assist heating, it means that the indoor ambient temperature has risen. At this time, the heat loss due to heat exchange during the process of hot air blowing towards the human body is small, so there is no need to turn on the electric heater to assist heating. Therefore, the electric heater is turned off.

[0090] It should be noted that in the above steps, whether the installation height is greater than the first preset height but less than the second preset height, or greater than the second preset height, the judgment condition for the electric heater to turn on for auxiliary heating and then turn off is the same in both cases: when the indoor ambient temperature is greater than the third preset temperature, the electric heater turns off, and the fan speed remains at its highest setting. However, this is not restrictive; the judgment conditions in these two cases can be the same or different, and the fan speed adjustment can also be different, as exemplified below:

[0091] In another embodiment, see Figure 4 Heating control methods also include:

[0092] S5. When the installation height is greater than the first preset height and less than the second preset height, the electric heater is on, and the fan speed is at its highest, compare the indoor ambient temperature with the fourth preset temperature.

[0093] S6, if the indoor ambient temperature is greater than the fourth preset temperature, control the electric heater to be turned off and control the fan speed to be restored to the user-set default state.

[0094] In the above steps, since the air conditioner is installed between the first and second preset heights, the hot air can descend smoothly. When the indoor ambient temperature reaches the fourth preset temperature, the fan can return to the default state set by the user, which helps to reduce energy consumption.

[0095] In another embodiment, see Figure 4 Heating control methods also include:

[0096] S7. When the installation height is greater than the second preset height, the electric heater is on, and the fan speed is at its highest, compare the indoor ambient temperature with the fifth preset temperature.

[0097] S8, if the indoor ambient temperature is greater than the fifth preset temperature, the electric heater will be turned off.

[0098] Among them, the fifth preset temperature is greater than the fourth preset temperature, and the fourth preset temperature is greater than the first preset temperature and the second preset temperature.

[0099] In the above steps, the air conditioner is installed at a height greater than the second preset height, so the hot air blown out moves downwards more slowly. Therefore, the fan speed is at its highest, which helps the hot air to descend smoothly.

[0100] It should be noted that, in the above steps, the specific values ​​of the first, second, third, fourth, and fifth preset temperatures are not specifically limited in this application, but can be flexibly designed according to usage requirements. For example, the first preset temperature is 18℃, the second preset temperature is 20℃, the third preset temperature is 22℃, the fourth preset temperature is 22℃, and the fifth preset temperature is 24℃. Furthermore, the specific values ​​of the first and second preset heights are not specifically limited in this application, but can be flexibly designed according to usage requirements. For example, the first preset height is 3m, and the second preset height is 3.5m.

[0101] In one embodiment, when the electric heater has at least two settings, the electric heater is at its highest setting when the installation height is greater than a first preset height and the electric heater is in the on state.

[0102] In one embodiment, a distance sensor is installed in the indoor unit, and the step of "obtaining the installation height of the indoor unit from the ground" further includes:

[0103] The installation height of the indoor unit from the ground is obtained based on the distance information detected by the distance sensor.

[0104] In addition, the present invention also provides an air conditioner, including a controller, the controller being configured to perform the heating control method of the air conditioning system described in any of the above technical solutions.

[0105] In the above-described embodiments and extended implementations, the present invention can adjust the working mode of the electric heater and fan according to the installation height of the indoor unit from the ground and the indoor ambient temperature. When the air conditioning system is in heating mode, it plays an auxiliary heating role, ensuring that the temperature of the hot air blown out from the air outlet after heat exchange with the air and then blown onto the human body is still within the range of comfortable temperature that the human body can accept. This makes the hot air feel comfortable when it blows onto the human body, and will not make the human body feel cold or chilly due to the lower temperature, thus improving the user experience.

[0106] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
