Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to a control method for an embedded air conditioner and an air conditioner. Background Technology

[0002] As people's demands for interior aesthetics and space utilization continue to increase, built-in air conditioners are increasingly being used in interior decoration. Built-in air conditioners are characterized by their small footprint, but their cooling effect, like other air conditioners, is linked to compressor power, refrigerant, and heat dissipation. In related technologies, built-in air conditioners are suspended from the ceiling. When the difference between the indoor ambient temperature and the set temperature of the built-in air conditioner is small, and the air conditioner is operating at high fan speed, the high-speed airflow from the vents blows directly onto the user, causing discomfort and severely impacting the user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a control method for an embedded air conditioner, which adjusts the set wind speed of the indoor fan to a target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode. At the target wind speed, the discomfort caused by high-speed airflow from the air outlet is reduced, thus improving the user experience.

[0004] This invention also provides an embedded air conditioner.

[0005] A control method for an embedded air conditioner according to a first aspect embodiment of the present invention includes:

[0006] Obtain the set temperature and fan speed mode of the embedded air conditioner, and obtain the indoor ambient temperature;

[0007] The indoor fan's set wind speed is adjusted to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature, and the wind speed mode. The wind speed difference between the target wind speed and the set wind speed is negatively correlated with the temperature difference.

[0008] According to an embodiment of the present invention, the step of adjusting the set wind speed of the indoor fan to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode specifically includes:

[0009] If the wind speed mode is determined to be medium wind speed mode or low wind speed mode, the target wind speed is maintained at the set wind speed.

[0010] If the wind speed mode is determined to be a high wind speed mode, then the wind speed compensation coefficient is determined based on the temperature difference;

[0011] The set wind speed is adjusted to the target wind speed according to the wind speed compensation coefficient.

[0012] According to an embodiment of the present invention, the step of determining the wind speed compensation coefficient based on the temperature difference specifically includes:

[0013] If the temperature difference is determined to be greater than the first temperature threshold, then the wind speed compensation coefficient is 1;

[0014] If the temperature difference is determined to be between the first temperature threshold and the second temperature threshold, then the wind speed compensation coefficient is the first wind speed compensation coefficient.

[0015] If the temperature difference is determined to be between the second temperature threshold and the third temperature threshold, then the wind speed compensation coefficient is the second wind speed compensation coefficient.

[0016] If the temperature difference is determined to be between the third temperature threshold and the fourth temperature threshold, then the wind speed compensation coefficient is the third wind speed compensation coefficient.

[0017] If the temperature difference is determined to be less than the fourth temperature threshold, then the wind speed compensation coefficient is the fourth wind speed compensation coefficient, and the product of the fourth wind speed compensation coefficient and the set wind speed is the minimum wind speed.

[0018] Among them, the first wind speed compensation coefficient, the second wind speed compensation coefficient, the third wind speed compensation coefficient, and the fourth wind speed compensation coefficient decrease sequentially, and all are less than 1.

[0019] According to an embodiment of the present invention, the step of determining the wind speed compensation coefficient based on the temperature difference further includes:

[0020] If the temperature difference is determined to be less than the fourth temperature threshold, then the wind speed compensation coefficient is the fourth wind speed compensation coefficient, and the product of the fourth wind speed compensation coefficient and the set wind speed is the wind speed in low wind speed mode or the wind speed in silent mode.

[0021] According to an embodiment of the present invention, the step of adjusting the set wind speed of the indoor fan to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode further includes:

[0022] Obtain the operating mode of the embedded air conditioner;

[0023] If the operating mode is determined to be cooling mode, then the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold are determined according to the set temperature; wherein the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold decrease sequentially.

[0024] According to an embodiment of the present invention, the step of determining the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold based on the set temperature further includes:

[0025] Among the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold, the difference between two adjacent temperature thresholds gradually decreases.

[0026] According to an embodiment of the present invention, the step of adjusting the set wind speed of the indoor fan to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode further includes:

[0027] Based on the temperature difference between the set temperature and the indoor ambient temperature, and the wind speed mode, the air guide plate of the air outlet of the embedded air conditioner is adjusted to the target air outlet direction; along the target air outlet direction, the air outlet avoids the area where the user is located in the room.

[0028] According to an embodiment of the present invention, the step of adjusting the air guide plate of the air outlet of the embedded air conditioner to the target air outlet direction based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode specifically includes:

[0029] If the wind speed mode is determined to be high wind speed mode and the temperature difference is less than the first temperature threshold, then the movement state of the air guide plate is adjusted to the sweeping mode in order to reduce the impact on the user through the sweeping mode.

[0030] According to one embodiment of the present invention, if a pressure sensor is provided at the air outlet, then the step of preventing the air outlet from venting the user's area in the room is further included before:

[0031] Based on historical data, the relationship between the swing angle of the air guide plate and the air pressure at the air outlet is obtained;

[0032] The air guide plate is controlled to swing at a constant speed between the minimum and maximum angles, and the swing angle of the air guide plate and the measured air pressure at the air outlet are obtained.

[0033] Based on the swing angle, the measured air pressure, and the corresponding relationship, the area where the user is located in the room is determined.

[0034] An embedded air conditioner according to a second aspect of the present invention is provided, wherein the embedded air conditioner executes a control method for an embedded air conditioner according to a first aspect of the present invention during operation.

[0035] The above-described one or more technical solutions of this invention have at least one of the following technical effects:

[0036] The control method for an embedded air conditioner according to an embodiment of the present invention includes the following steps: acquiring the set temperature and fan speed mode of the embedded air conditioner, and acquiring the indoor ambient temperature; adjusting the set fan speed of the indoor fan to a target fan speed based on the temperature difference between the set temperature and the indoor ambient temperature and the fan speed mode, wherein the fan speed difference between the target fan speed and the set fan speed is negatively correlated with the temperature difference. When the embedded air conditioner is running, for example in cooling mode, if the difference between the set temperature and the indoor ambient temperature is small, and the indoor fan operates at a high fan speed, the air outlet of the embedded air conditioner will blow air at high speed towards the user, causing the user to directly contact cold air, thus reducing the user's comfort. The control method for an embedded air conditioner provided by this embodiment of the present invention can adjust the set fan speed of the indoor fan to a target fan speed based on the temperature difference between the set temperature and the indoor ambient temperature and the fan speed mode. When the temperature difference between the set fan speed and the indoor ambient temperature is large, heat exchange occurs between the indoor air and the air outlet, adjusting the outlet air temperature to some extent. This means the indoor air heats the excessively cold outlet air or cools the excessively hot outlet air, mitigating the discomfort caused by high-speed airflow directed at the user. Therefore, the indoor fan speed can be left unchanged or adjusted only slightly. Conversely, when the temperature difference between the set temperature and the indoor ambient temperature is small, the indoor fan speed is significantly reduced to prevent either low-temperature or high-temperature airflow from the outlet from blowing directly at the user at high speed. This reduces user discomfort, improves user comfort, and enhances the user experience. Attached Figure Description

[0045] In related technologies, embedded air conditioners are suspended from the ceiling of the room. The difference between the indoor ambient temperature and the set temperature of the embedded air conditioner is small. When the air conditioner is running in high fan speed mode, the air outlet blows directly onto the user, which can cause discomfort and seriously affect the user experience.

[0046] The indoor unit of the embedded air conditioner provided in this embodiment of the invention is installed at the top of the room. Multiple air outlets are provided on the side of the embedded air conditioner facing the room, and each air outlet is equipped with an air guide plate to adjust the airflow direction. In some cases, a temperature sensing element is provided at the indoor unit; in other cases, temperature sensing elements can also be installed at other locations in the room; the temperature sensing elements at different locations are all used to detect the indoor ambient temperature.

[0047] For the control method of the embedded air conditioner provided in the first aspect embodiment of the present invention, please refer to [link / reference needed]. Figure 1 and Figure 2 This includes the following steps:

[0048] S100: Obtain the set temperature and fan speed mode of the embedded air conditioner, and obtain the indoor ambient temperature.

[0049] S200: Based on the temperature difference between the set temperature and the indoor ambient temperature, as well as the wind speed mode, adjust the set wind speed of the indoor fan to the target wind speed. The wind speed difference between the target wind speed and the set wind speed is negatively correlated with the temperature difference.

[0050] In step S100, when the embedded air conditioner is running, the control unit, in response to the operating signal, acquires the set temperature and fan speed mode of the embedded air conditioner. The set temperature refers to the control parameter input by the user via remote control or control panel, or it can be a control parameter that the air conditioner automatically adjusts based on indoor and outdoor temperature and humidity. The fan speed mode includes the fan speed mode manually input by the user and the fan speed mode automatically adjusted by the embedded air conditioner according to the control logic. In actual use, this includes low fan speed mode, medium fan speed mode, high fan speed mode, and silent mode, etc.

[0051] In step S200, the set fan speed of the indoor fan is adjusted to the target fan speed based on the temperature difference between the set temperature and the indoor ambient temperature, as well as the fan speed mode. The difference between the target fan speed and the set fan speed is negatively correlated with the temperature difference. When the embedded air conditioner is running, for example in cooling mode, if the difference between the set temperature and the indoor ambient temperature is small, and the indoor fan operates at a high fan speed, the airflow from the air conditioner's outlet will blow directly onto the user at high speed, causing the user to be directly exposed to cold air. This high-speed, direct cold airflow reduces the user's comfort. The embedded air conditioner control method provided in this embodiment of the invention can adjust the set fan speed of the indoor fan to the target fan speed based on the temperature difference between the set temperature and the indoor ambient temperature, as well as the fan speed mode. When the temperature difference between the set fan speed and the indoor ambient temperature is large, heat exchange occurs between the indoor air and the airflow from the outlet, and the temperature of the outlet air is adjusted to a certain extent. That is, the indoor air heats the excessively cold outlet air or cools the relatively hot outlet air, mitigating the discomfort caused by the high-speed airflow blowing directly onto the user. Therefore, the fan speed of the indoor fan can be adjusted only slightly or not at all. When the temperature difference between the set temperature and the indoor ambient temperature is small, the air speed of the indoor fan is significantly reduced to prevent low-temperature air or high-temperature air from blowing directly at the user, thereby reducing user discomfort, improving user comfort, and enhancing the user experience.

[0052] In some embodiments, the step of adjusting the set wind speed of the indoor fan to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode specifically includes:

[0053] S210. If the wind speed mode is determined to be medium wind speed mode or low wind speed mode, the target wind speed will be maintained at the set wind speed.

[0054] S220. If the wind speed mode is determined to be high wind speed mode, then the wind speed compensation coefficient is determined based on the temperature difference.

[0055] S230. Adjust the set wind speed to the target wind speed according to the wind speed compensation coefficient.

[0056] In step S210, when the fan speed mode is medium or low, the airflow from the air outlet of the embedded air conditioner is relatively weak when it blows towards the user. During the airflow towards the user, it can exchange heat with the indoor air, and the temperature of the air outlet will be adjusted to a certain extent. Therefore, in medium or low fan speed mode, the airflow from the air outlet is relatively gentle when it reaches the user and will not cause discomfort to the user, or the user's discomfort is relatively mild. At this time, it is not necessary to adjust the fan speed of the indoor fan, and the target fan speed is maintained at the set fan speed.

[0057] In step S220, when the fan speed mode is high, the airflow from the vent flows towards the user at a high speed. In cooling mode, this high-speed cold air blowing directly onto the user can cause severe discomfort. Additionally, if the indoor ambient temperature is 22 degrees Celsius and the set temperature is 16 degrees Celsius, the large temperature difference between the set temperature and the indoor ambient temperature allows the indoor air to heat the high-speed cold air. This heated cold air reduces discomfort upon reaching the user, thus requiring less or no fan speed compensation. However, as the indoor ambient temperature decreases, for example to 18 degrees Celsius, the temperature difference between the set temperature and the indoor ambient temperature decreases. The cold air blowing towards the user experiences less heat exchange with the indoor air, resulting in a still low temperature. This high-speed cold air can cause severe discomfort, necessitating a larger fan speed compensation and a greater reduction in fan speed. In other words, the difference between the target fan speed and the set fan speed is negatively correlated with the temperature difference.

[0058] In step S230, the set wind speed is adjusted to the target wind speed according to the wind speed compensation coefficient. The smaller the temperature difference, the larger the compensation coefficient, and the greater the reduction in wind speed. This can prevent the cold or hot air from the air outlet from blowing directly onto the user, thus avoiding discomfort.

[0059] In some embodiments, the step of determining the wind speed compensation coefficient based on the temperature difference specifically includes:

[0060] S221. If the temperature difference is greater than the first temperature threshold, then the wind speed compensation coefficient is 1.

[0061] S222. If the temperature difference is determined to be between the first temperature threshold and the second temperature threshold, then the wind speed compensation coefficient is the first wind speed compensation coefficient.

[0062] S223. If the temperature difference is determined to be between the second temperature threshold and the third temperature threshold, then the wind speed compensation coefficient is the second wind speed compensation coefficient.

[0063] S224. If the temperature difference is determined to be between the third temperature threshold and the fourth temperature threshold, then the wind speed compensation coefficient is the third wind speed compensation coefficient.

[0064] S225. If the temperature difference is determined to be less than the fourth temperature threshold, then the wind speed compensation coefficient is the fourth wind speed compensation coefficient, and the product of the fourth wind speed compensation coefficient and the set wind speed is the minimum wind speed. Among them, the first wind speed compensation coefficient, the second wind speed compensation coefficient, the third wind speed compensation coefficient, and the fourth wind speed compensation coefficient decrease sequentially, and all are less than 1.

[0065] In embodiments of the present invention, the first wind speed compensation coefficient, the second wind speed compensation coefficient, the third wind speed compensation coefficient, and the fourth wind speed compensation coefficient are all proportional coefficients, such as 0.95, 0.9, 0.8, and 0.7. The selection of these values ​​needs to be determined in conjunction with the indoor structural characteristics and the user's own experience, and can be set according to needs when the air conditioner is first started. The first wind speed compensation coefficient, the second wind speed compensation coefficient, the third wind speed compensation coefficient, and the fourth wind speed compensation coefficient decrease sequentially, and are all less than 1.

[0066] In step S221, the temperature difference is greater than the first temperature threshold, for example, the temperature difference is greater than 4 degrees Celsius. At this time, the heat exchange efficiency between indoor air and cold or hot air is relatively high, and the cold or hot air is relatively mild after heat exchange. At this time, the wind speed compensation coefficient is 1, and the set temperature is not compensated.

[0067] In step S222, the temperature difference is between the first temperature threshold and the second temperature threshold, for example, 4 degrees Celsius ≥ temperature difference > 3 degrees Celsius. At this time, the heat exchange efficiency between indoor air and cold or hot air is relatively high, and the cold or hot air is relatively mild after heat exchange. At this time, the wind speed compensation coefficient is the first wind speed compensation coefficient, for example, the first wind speed compensation coefficient is 0.95.

[0068] In step S223, the temperature difference is between the second temperature threshold and the third temperature threshold, for example, 3 degrees Celsius ≥ temperature difference > 2 degrees Celsius. At this time, the heat exchange efficiency between indoor air and cold or hot air is low. At this time, the wind speed compensation coefficient is the second wind speed compensation coefficient, for example, the second wind speed compensation coefficient is 0.90.

[0069] In step S224, the temperature difference is between the third temperature threshold and the fourth temperature threshold, for example, 2 degrees Celsius ≥ temperature difference > 1 degree Celsius. At this time, the heat exchange efficiency between indoor air and cold or hot air is low, and the cold or hot air brings greater stimulation to the user. At this time, the wind speed compensation coefficient is the third wind speed compensation coefficient, for example, the third wind speed compensation coefficient is 0.80.

[0070] In step S225, if the temperature difference is less than or equal to the fourth temperature threshold, for example, if the temperature difference is ≤1 degree Celsius, the heat exchange efficiency between indoor air and cold or hot air is low or non-exchange. Users are more sensitive to high-speed flowing cold or hot air. At this time, the wind speed compensation coefficient is the fourth wind speed compensation coefficient. The product of the fourth wind speed compensation coefficient and the set wind speed is the minimum wind speed. That is, when the temperature difference is less than the fourth temperature threshold, the set wind speed is immediately adjusted to the minimum wind speed to reduce the impact on users.

[0071] In some embodiments, the step of determining the wind speed compensation coefficient based on the temperature difference further includes:

[0072] S226. If the temperature difference is less than the fourth temperature threshold, then the wind speed compensation coefficient is the fourth wind speed compensation coefficient, and the product of the fourth wind speed compensation coefficient and the set wind speed is the wind speed of the low wind speed mode or the wind speed of the silent mode.

[0073] In step S226, if the temperature difference is less than the fourth temperature threshold, for example, the temperature difference is <1 degree Celsius, the heat exchange efficiency between indoor air and cold or hot air is low or non-exchange, and cold or hot air is more sensitive. At this time, the wind speed compensation coefficient is the fourth wind speed compensation coefficient, and the product of the fourth wind speed compensation coefficient and the set wind speed is the wind speed of the low wind speed mode or the wind speed of the silent mode, that is, the set wind speed is adjusted to the wind speed of the low wind speed mode or the wind speed of the silent mode.

[0074] In some embodiments, the step of adjusting the set wind speed of the indoor fan to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode further includes:

[0075] S240, Obtain the operating mode of the embedded air conditioner.

[0076] S241. If the operating mode is determined to be cooling mode, then the first temperature threshold, the second temperature threshold, the third temperature threshold and the fourth temperature threshold are determined according to the set temperature; wherein the first temperature threshold, the second temperature threshold, the third temperature threshold and the fourth temperature threshold decrease sequentially.

[0077] In step S240, the operating mode of the embedded air conditioner includes cooling mode or heating mode. In cooling mode, it is necessary to avoid blowing cold air towards the user at high fan speed, and in heating mode, it is necessary to avoid blowing hot air towards the user at high fan speed. Since the human body has different tolerance levels for low and high temperatures, and each person has their own preferences, for example, a suitable high temperature will improve the comfort of some users when cooling in winter, or a suitable low temperature will improve the comfort of some users when heating in summer. The temperature threshold is related to the selected set temperature (temperature preference). Therefore, a first temperature threshold, a second temperature threshold, a third temperature threshold, and a fourth temperature threshold can be determined based on the set temperature. The first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold decrease sequentially. For example, the first temperature threshold is 4 degrees Celsius, the second temperature threshold is 3 degrees Celsius, the third temperature threshold is 2 degrees Celsius, and the fourth temperature threshold is 1 degree Celsius.

[0078] In some embodiments, the step of determining the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold based on a set temperature further includes:

[0079] S242. Among the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold, the difference between two adjacent temperature thresholds gradually decreases.

[0080] In step S242, as the temperature difference between the indoor ambient temperature and the set temperature decreases, the heat exchange efficiency between the cold or hot air at the air outlet and the indoor air drops sharply, resulting in a stronger impact on the user. Therefore, when the temperature difference is small, appropriately reducing the difference between two adjacent temperature thresholds, for example, setting the first temperature threshold to 4 degrees Celsius, the second to 3 degrees Celsius, the third to 2.2 degrees Celsius, and the fourth to 1.6 degrees Celsius, can improve the sensitivity of wind speed compensation. In this case, the wind speed does not need to reach an unbearable threshold for the user to compensate in a timely manner, thus improving the user's comfort.

[0081] In some embodiments, the step of adjusting the set wind speed of the indoor fan to the target wind speed based on the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode further includes:

[0082] S250: Adjust the air guide plate of the air outlet of the embedded air conditioner to the target air outlet direction according to the temperature difference between the set temperature and the indoor ambient temperature and the wind speed mode; along the target air outlet direction, the air outlet avoids the area where the user is in the room.

[0083] In step S250, when the temperature difference between the set temperature and the indoor ambient temperature is small and the fan speed mode is high, the cold or hot air from the air outlet blowing directly at the user will cause severe discomfort. At this time, the air guide can be adjusted to the target air outlet direction. Along the target air outlet direction, the air outlet avoids the area where the user is in the room, preventing the cold or hot air from the air outlet from blowing directly at the user at high speed, reducing the user's discomfort and improving the user experience.

[0084] In some embodiments, the step of adjusting the air guide plate of the embedded air conditioner's air outlet to the target air outlet direction based on the temperature difference between the set temperature and the indoor ambient temperature and the fan speed mode specifically includes:

[0085] S260. If the wind speed mode is determined to be high wind speed mode and the temperature difference is less than the first temperature threshold, then the movement state of the air guide plate is adjusted to the sweeping mode in order to reduce the impact on the user through the sweeping mode.

[0086] In step S260, when the fan speed mode is high and the temperature difference is less than a first temperature threshold (e.g., less than 4 degrees Celsius), the cold or hot air from the air outlet may cause discomfort to the user. The air guide vane is then adjusted to a swing mode to reduce the impact of the cold or hot air on the user. In swing mode, the cold or hot air from the air outlet will not blow directly at the user, and the swing process increases the temperature uniformity of the indoor air, improving the user experience.

[0087] In some embodiments, if a pressure sensor is provided at the air outlet, the step of directing the airflow from the air outlet to avoid the area where the user is located in the room is further included before:

[0088] S251. Read the correspondence between the swing angle of the air guide plate and the air pressure at the air outlet based on historical data.

[0089] S252. Control the air guide plate to swing at a constant speed between the minimum and maximum angles, and obtain the swing angle of the air guide plate and the measured air pressure at the air outlet.

[0090] S253. Determine the area where the user is located in the room based on the swing angle, measured air pressure, and corresponding relationships.

[0091] In step S251, based on the indoor structure of the room where the embedded air conditioner is located and the placement of furniture, different structures and placements will have a certain impact on the airflow from the air outlet. When the installation position of the embedded air conditioner remains unchanged, the impact on the airflow from the air outlet is definite, and at a specific angle, the air pressure at the air outlet is also definite. After the air guide plate at the air outlet swings back and forth multiple times, multiple sets of historical data are generated. Based on the historical data, the correspondence between the swing angle of the air guide plate and the air pressure at the air outlet can be calculated. This correspondence, after multiple calculations and fitting, has a certain representativeness.

[0092] In step S252, the air guide plate is controlled to swing uniformly between the minimum and maximum angles, and the swing angle of the air guide plate and the measured air pressure at the air outlet are obtained. When the air from the air outlet blows towards the user's area, the airflow and measured air pressure at the air outlet will change due to the obstruction of the airflow by the user's body. Although the change is slight, it can still be detected.

[0093] In step S253, by scanning the area where the user is located through a stable airflow, and comparing the feedback value of the measured air pressure with the corresponding relationship, the area where the moving person or object is located can be determined, thereby determining the area where the user is located or lives in the room.

[0094] According to the second aspect of the present invention, the embedded air conditioner executes the control method of the embedded air conditioner according to the first aspect of the present invention during operation.

[0095] When an embedded air conditioner is running, for example in cooling mode, if the difference between the set temperature and the indoor ambient temperature is small, and the indoor fan is operating at a high speed, the airflow from the air conditioner's outlet will blow directly onto the user at high speed, causing the user to be directly exposed to cold air. This high-speed, direct blast of cold air reduces user comfort. The control method for the embedded air conditioner provided in this invention can adjust the set fan speed to the target speed based on the temperature difference between the set temperature and the indoor ambient temperature, as well as the fan speed mode. When the temperature difference between the set fan speed and the indoor ambient temperature is large, heat exchange occurs between the indoor air and the air outlet, adjusting the outlet air temperature to a certain extent. Specifically, the indoor air heats the excessively cold outlet air or cools the relatively hot outlet air, mitigating the discomfort caused by the high-speed airflow blowing directly onto the user. Therefore, the indoor fan speed can be adjusted only slightly or not at all. When the temperature difference between the set temperature and the indoor ambient temperature is small, the air speed of the indoor fan is significantly reduced to prevent low-temperature air or high-temperature air from blowing directly at the user, thereby reducing user discomfort, improving user comfort, and enhancing the user experience.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
