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 typically suspended from the ceiling. When the room's ceiling height increases, the air outlet of the air conditioner needs to travel a longer path to reach the user's area. Under the influence of the indoor ambient temperature, the temperature of the outlet air may change, leading to variations in the temperature of the air flowing to the user. This can result in the air not meeting the user's actual needs 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 an embedded air conditioner that adjusts the air outlet direction of the embedded air conditioner to a target air outlet direction based on the indoor floor height and indoor ambient temperature. Following the target air outlet direction improves the heat exchange path length of the air outlet, preventing hot or cold air from traveling too long a heat exchange path when there is a large temperature difference with the indoor ambient temperature. This reduces the temperature change of the air outlet and improves the user experience.

[0014] If the indoor floor height is determined to be greater than the first height and the temperature difference is less than the first temperature threshold, then the compensation angle of the air guide plate is the first compensation angle.

[0015] If the indoor floor height is greater than the first height and the temperature difference is between the first temperature threshold and the second temperature threshold, then the compensation angle of the air guide plate is the second compensation angle.

[0016] If the indoor floor height is greater than the first height and the temperature difference is between the second temperature threshold and the third temperature threshold, then the compensation angle of the air guide plate is the third compensation angle, and the sum of the third compensation angle and the preset angle is the minimum air guide angle.

[0017] The first compensation angle, the second compensation angle, and the third compensation angle are negative values, and decrease sequentially.

[0018] According to an embodiment of the present invention, the step of determining the compensation angle of the air guide plate of the air outlet based on the indoor floor height and the temperature difference further includes:

[0019] If the indoor floor height is determined to be greater than the first height and the temperature difference is greater than the third temperature threshold, then the fan speed of the indoor unit is adjusted to the maximum fan speed.

[0020] According to one embodiment of the present invention, the step of adjusting the fan speed of the indoor unit to the maximum fan speed further includes:

[0021] Activate the temperature assist device and adjust the outlet air temperature through the temperature assist device.

[0022] According to one embodiment of the present invention, the step of determining the compensation angle of the air guide plate of the air outlet based on the indoor floor height and the temperature difference further includes, prior to:

[0023] Obtain the operating mode of the embedded air conditioner;

[0024] The first temperature threshold, the second temperature threshold, and the third temperature threshold are determined based on the operating mode and the set temperature.

[0025] According to one embodiment of the present invention, a top-to-bottom ventilation duct is provided on the side wall of the room where the embedded air conditioner is located. An air inlet is provided at the position of the ventilation duct facing the minimum air guiding angle of the air guide plate, and an air outlet is provided at the bottom of the ventilation duct facing the user's area. The step of adjusting the air outlet direction of the embedded air conditioner to the target air outlet direction according to the indoor floor height and the indoor ambient temperature further includes:

[0026] If the indoor floor height is determined to be greater than the second height, or the temperature difference is greater than the fourth temperature threshold, then the air guide plate is adjusted to the minimum air guide angle so that air is blown into the room through the ventilation channel.

[0027] According to one embodiment of the present invention, the number of ventilation channels can be one or more, and the ventilation channels are installed in the wall by embedding them into the wall.

[0028] According to an embodiment of the present invention, the step of adjusting the air outlet direction of the embedded air conditioner to the target air outlet direction based on the indoor floor height and the indoor ambient temperature specifically includes:

[0029] Obtain the operating mode of the embedded air conditioner;

[0030] If the operating mode is determined to be heating mode and the indoor floor height is greater than the first height, then the air outlet direction of the embedded air conditioner is adjusted to the target air outlet direction according to the indoor ambient temperature.

[0032] The above-described one or more technical solutions of this invention have at least one of the following technical effects:

[0033] The control method for an embedded air conditioner according to an embodiment of the present invention includes the following steps: in response to an operating signal, acquiring the indoor floor height and indoor ambient temperature of the room where the embedded air conditioner is located; adjusting the air outlet direction of the embedded air conditioner to a target air outlet direction based on the indoor floor height and indoor ambient temperature; along the target air outlet direction, the heat exchange path length of the air outlet is negatively correlated with the temperature difference between the indoor ambient temperature and the set temperature. When the embedded air conditioner is running, if the air outlet blows out at a preset angle, and the difference between the indoor ambient temperature and the set temperature is large, the air outlet needs to travel a long heat exchange path and undergo a long heat exchange process before reaching the user's area. The temperature of the air outlet changes significantly after heat exchange, making it difficult to meet the user's needs. When the airflow reaches the user's area or blows directly onto the user, it can cause discomfort and reduce user comfort. The control method for an embedded air conditioner provided in this invention adjusts the air outlet direction of the embedded air conditioner to a target air outlet direction based on the indoor floor height and indoor ambient temperature. Along the target air outlet direction, the heat exchange path length of the air outlet is negatively correlated with the temperature difference between the indoor ambient temperature and the set temperature. As the temperature difference between the indoor ambient temperature and the set temperature increases, the heat exchange path length of the air outlet is shortened, reducing heat exchange between the air outlet and the indoor air. This prevents air with large temperature variations from blowing directly onto the user's area or onto the user, reducing user discomfort and improving the user experience.

[0042] In related technologies, embedded air conditioners are generally suspended from the ceiling of a room. As the indoor height of the room increases, the air outlet of the air conditioner needs to travel a longer path to reach the user's area. The temperature of the air outlet may change under the influence of the ambient temperature, which in turn leads to changes in the temperature of the airflow flowing to the user, failing to meet the user's actual needs and seriously affecting the user's experience.

[0043] 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.

[0044] Embedded air conditioners can obtain information about the indoor floor height of the room where the air conditioner is located. In one case, the embedded air conditioner includes a distance sensor for detecting the indoor floor height, and the indoor floor height is determined based on the detection result of the distance sensor. In another case, the indoor floor height is basic information of the building structure, and the indoor floor height information can be directly input through the control panel or remote control of the air conditioner.

[0045] For a control method of an embedded air conditioner provided according to a first aspect embodiment of the present invention, please refer to [link to relevant documentation]. Figures 1 to 2 This includes the following steps:

[0046] S100: In response to the operation signal, obtain the indoor floor height and indoor ambient temperature of the room where the embedded air conditioner is located.

[0047] S200. Adjust the air outlet direction of the embedded air conditioner to the target air outlet direction according to the indoor floor height and indoor ambient temperature; along the target air outlet direction, the heat exchange path length of the air outlet is negatively correlated with the temperature difference between the indoor ambient temperature and the set temperature.

[0048] In step S100, during the operation of the embedded air conditioner, the indoor floor height of the room where the embedded air conditioner is located is obtained through a distance sensor, and the indoor ambient temperature is obtained through a temperature detection element. The set temperature of the embedded air conditioner can be directly read. In different operating modes, the air outlet direction has a preset direction / preset angle, which is executed according to the original control logic stored in the embedded air conditioner.

[0049] In step S200, the air outlet direction of the embedded air conditioner is adjusted to the target air outlet direction based on the indoor ceiling height and indoor ambient temperature. As the indoor ceiling height increases, the distance between the air outlet and the indoor floor or the user increases, requiring the airflow to travel a longer distance to reach the user's area or blow onto the user. When the temperature difference between the indoor ambient temperature and the set temperature of the embedded air conditioner is large, the airflow from the outlet needs to travel a longer heat exchange path and undergo a longer heat exchange process before reaching the user's area or blowing onto the user. In this case, due to the longer heat exchange path and larger heat exchange, the airflow from the outlet will experience significant temperature changes. The large temperature difference between the airflow blowing onto the user and the set temperature can cause discomfort for the user, reducing user comfort and user experience. According to the control method for the embedded air conditioner provided in this embodiment, the air outlet direction of the embedded air conditioner can be adjusted to the target air outlet direction based on the indoor ceiling height and indoor ambient temperature. Furthermore, along the target air outlet direction, the heat exchange path length of the airflow from the outlet is negatively correlated with the temperature difference between the indoor ambient temperature and the set temperature. When there is a large temperature difference between the indoor ambient temperature and the set temperature, adjust the air outlet direction to reduce the heat exchange path between the air outlet and the indoor air, thereby reducing the temperature change of the air outlet.

[0050] As the temperature difference between the indoor environment and the set temperature increases, the heat exchange path length of the air outlet is shortened, reducing the heat exchange process between the air outlet and the indoor air. This prevents the air with large temperature changes from blowing directly onto the user's area or onto the user, reducing user discomfort and improving the user experience.

[0051] According to one embodiment of the present invention, the step of adjusting the air outlet direction of the embedded air conditioner to the target air outlet direction based on the indoor floor height and indoor ambient temperature specifically includes:

[0052] S210. Obtain the set temperature of the embedded air conditioner and calculate the temperature difference between the indoor ambient temperature and the set temperature.

[0053] S220. Determine the compensation angle of the air outlet guide plate based on the indoor floor height and temperature difference.

[0054] S230. Adjust the air guide plate to the target air outlet angle according to the compensation angle and the preset angle of the air guide plate.

[0055] In step S210, the set temperature can be obtained by reading the control parameters inside the embedded air conditioner. Based on the set temperature, it can be determined whether the current mode is heating or cooling. The embedded air conditioner controls its operation under the influence of the set temperature. At the same time, the difference between the indoor ambient temperature and the set temperature is calculated, which can clarify whether the indoor ambient temperature has an impact on the airflow from the air outlet and how much that impact is.

[0056] In step S220, as the indoor ceiling height increases, the distance between the air outlet of the embedded air conditioner and the user's area increases. As the temperature difference between the indoor environment and the set temperature increases, the heat exchange efficiency of the airflow from the outlet increases. The indoor ceiling height affects the heat exchange path length, and the temperature difference affects the heat exchange efficiency of the airflow path. Therefore, the compensation angle of the air guide plate at the air outlet can be determined based on the influence of the indoor ceiling height and temperature difference on the airflow. It should be noted that the air guide plate is horizontal at 0° and vertical at 90°. The air guide plate can move continuously between 0° and 90°, so the compensation angle can be a specific angle value, such as 15°. The air guide plate can also have multiple position settings between 0° and 90°, such as position 1, position 2, position 3, position 4, position 5, etc., and the compensation angle can be one position setting, such as ±1 position setting. When the compensation angle is positive, the air guide plate continues to tilt downward; when the compensation angle is negative, the air guide plate moves towards the horizontal direction from its original position.

[0057] In step S230, the air guide plate is adjusted to the target air outlet angle according to the compensation angle and the preset angle of the air guide plate. At the target air outlet angle, the air outlet flows along the target air outlet direction, which can reduce the heat exchange between the air outlet and the indoor air with a large temperature difference.

[0058] According to an embodiment of the present invention, the step of determining the compensation angle of the air outlet guide plate based on the indoor floor height and temperature difference specifically includes:

[0059] S221. If the indoor floor height is less than or equal to the first height, then the compensation angle of the air guide plate is zero.

[0060] S222. If the indoor floor height is greater than the first height and the temperature difference is less than the first temperature threshold, then the compensation angle of the air guide plate is the first compensation angle.

[0061] S223. If the indoor floor height is greater than the first height and the temperature difference is between the first temperature threshold and the second temperature threshold, then the compensation angle of the air guide plate is the second compensation angle.

[0062] S224. If the indoor floor height is greater than the first height and the temperature difference is between the second and third temperature thresholds, then the compensation angle of the air guide plate is the third compensation angle, and the sum of the third compensation angle and the preset angle is the minimum air guide angle.

[0063] Among them, the first compensation angle, the second compensation angle, and the third compensation angle are negative values, and decrease in sequence.

[0064] In step S221, when the indoor floor height is less than or equal to the first height, for example, the indoor floor height is ≤3m, the indoor floor height is the same as that of ordinary housing or office areas, and the heat exchange path length has not changed significantly. Therefore, there is no need to adjust the angle of the air guide plate, and the compensation angle is zero.

[0065] It should be noted that the embedded air conditioner may operate in heating mode or cooling mode. Therefore, the temperature difference mentioned in this embodiment refers to the situation where the indoor ambient temperature is too low in heating mode or too high in cooling mode.

[0066] In step S222, when the indoor floor height is greater than the first height, the increased indoor floor height leads to an increased heat exchange path length for the air outlet. When the temperature difference is less than the first temperature threshold, it indicates that the heat exchange efficiency of the air outlet is not high, and the angle of the air guide plate can be adjusted appropriately. Therefore, the compensation angle is the first compensation angle, such as -15° or the air guide plate can be raised one position.

[0067] In step S223, the indoor floor height is greater than the first height. With the increased indoor floor height, the heat exchange path length of the air outlet increases. When the temperature difference is between the first and second temperature thresholds, the heat exchange efficiency of the air outlet is high. Therefore, it is necessary to increase the compensation angle of the air guide plate to ensure that the airflow avoids the user's area and prevents the airflow from blowing directly at the user. In this case, the compensation angle of the air guide plate is the second compensation angle, such as -30° or two upward-facing positions.

[0068] In step S224, when the temperature difference is between the second temperature threshold and the third temperature threshold, the heat exchange efficiency of the air outlet is relatively high. It is necessary to increase the compensation angle of the air guide plate to avoid the area where the user is located as much as possible, and avoid the air outlet blowing directly towards the user. The air guide plate is adjusted to the minimum air outlet angle so that the air outlet completely avoids the user, thereby reducing the user's discomfort.

[0069] According to an embodiment of the present invention, the step of determining the compensation angle of the air outlet guide plate based on the indoor floor height and temperature difference further includes:

[0070] S225. If the indoor floor height is greater than the first height and the temperature difference is greater than the third temperature threshold, then adjust the indoor unit's fan speed to the maximum fan speed.

[0071] In step S225, when the indoor floor height is greater than the first height and the temperature difference is greater than the third temperature threshold, the heat exchange path length is relatively long and the heat exchange efficiency between the indoor air and the air outlet is relatively high, which has a significant impact on the temperature of the air outlet. In this embodiment, the indoor unit's fan speed is adjusted to the maximum speed. At this time, the heat exchange efficiency between the air outlet and the heat exchanger increases, which can increase the heat or cold carried in the air outlet, thereby offsetting the influence of the indoor air and reducing the temperature fluctuation of the air outlet, thus improving user comfort.

[0072] According to one embodiment of the present invention, the step of adjusting the fan speed of the indoor unit to the maximum fan speed further includes:

[0073] S226. Activate the temperature auxiliary device and adjust the outlet air temperature through the temperature auxiliary device.

[0074] In step S226, a temperature auxiliary device is installed at the air outlet (inside the indoor unit) of the embedded air conditioner. The temperature auxiliary device can be an electric heating element, suitable for the air conditioner in heating mode; or it can be a semiconductor refrigeration element, suitable for the air conditioner in cooling mode. When the temperature difference is large, the indoor air has a greater impact on the air outlet. At this time, activating the temperature auxiliary device to adjust the temperature of the air outlet helps to improve the user's perceived temperature and enhances user comfort.

[0075] According to one embodiment of the present invention, the step of determining the compensation angle of the air outlet guide plate based on the indoor floor height and temperature difference further includes, before:

[0076] S227. Obtain the operating mode of the embedded air conditioner.

[0077] S228. Determine the first temperature threshold, the second temperature threshold, and the third temperature threshold based on the operating mode and the set temperature.

[0078] It is understandable that an embedded air conditioner can operate in either cooling or heating mode. In heating mode, it is necessary to avoid the influence of cold indoor air on the air outlet, while in cooling mode, it is necessary to avoid the influence of hot indoor air on the air outlet. Therefore, the values ​​of the first, second, and third temperature thresholds are related to the set temperature and the operating mode. Determining different temperature thresholds for different set temperatures or operating modes can improve the applicability of the control method for the embedded air conditioner provided in this embodiment of the invention.

[0079] As indoor ceiling heights continue to increase, it becomes increasingly difficult for the air outlets of recessed air conditioners to directly blow air onto the ground or the user's area. For example, if a recessed air conditioner is installed in a villa or showroom, users on the floor may not be able to feel its presence. Therefore, it is necessary to direct the airflow from the outlets to the user's location as much as possible.

[0080] According to one embodiment of the present invention, a top-to-bottom ventilation duct is provided on the side wall of the room where the embedded air conditioner is located. An air inlet is located at the position of the minimum air guiding angle of the ventilation duct towards the air guide plate, and an air outlet is located at the bottom of the ventilation duct facing the user's area. The ventilation duct can directly guide the air outlet of the air conditioner at the top of the room to a lower position in the room. Since this portion of the air outlet only passes through the ventilation duct, heat exchange with other parts of the room is minimal, maintaining the original temperature and improving the user experience. The step of adjusting the air outlet direction of the embedded air conditioner to the target air outlet direction according to the indoor ceiling height and indoor ambient temperature further includes:

[0081] S240. If the indoor floor height is greater than the second height or the temperature difference is greater than the fourth temperature threshold, adjust the air guide plate to the minimum air guide angle so that air is blown into the room through the ventilation channel.

[0082] In step S240, when the indoor floor height is greater than the second height, or the temperature difference is greater than the fourth temperature threshold, the impact on the air outlet is significant. The ventilation duct can directly guide the air outlet of the air conditioner at the top of the room to a lower position in the room, directly reaching the user's area. This part of the air outlet only passes through the ventilation duct, with less heat exchange with other parts of the room, which can maintain the original temperature and improve the user experience.

[0083] According to one embodiment of the present invention, the number of ventilation channels can be one or more, and the ventilation channels are installed in the wall by embedding them into the wall.

[0084] Understandably, there can be one ventilation duct to assist the built-in air conditioner's air outlet in guiding airflow to a lower position in the room; or there can be multiple ventilation ducts, with the number of ducts matching the number of air outlets in the built-in air conditioner, and both being configured in a one-to-one correspondence. In this case, the airflow from the outlet can evenly enter the room and reach the user's area along multiple ventilation ducts. The ventilation ducts are installed embedded in the wall, reducing space occupation and improving the cleanliness and aesthetics of the room.

[0085] According to one embodiment of the present invention, the step of adjusting the air outlet direction of the embedded air conditioner to a target air outlet direction based on the indoor floor height and the indoor ambient temperature specifically includes:

[0086] S250: Obtain the operating mode of the embedded air conditioner.

[0087] S251. If the operating mode is determined to be heating mode and the indoor floor height is greater than the first height, then adjust the air outlet direction of the embedded air conditioner to the target air outlet direction according to the indoor ambient temperature.

[0088] In step S251, when the embedded air conditioner is operating in heating mode and the indoor floor height is greater than the first height, for example, >3m, the air outlet direction of the embedded air conditioner is adjusted to the target air outlet direction according to the indoor ambient temperature. The following example illustrates step S251:

[0089] When the indoor ambient temperature is above 20 degrees Celsius, the high indoor temperature has little impact on the airflow from the air outlet, and there is no need to adjust the angle of the air guide plate.

[0090] When the indoor ambient temperature is between 15 and 20 degrees Celsius, the low indoor temperature affects the airflow from the air outlet. In this case, the air guide plate should be raised to a higher position.

[0091] When the indoor ambient temperature is between 10 and 15 degrees Celsius, the low indoor temperature has a greater impact on the airflow from the air outlet. In this case, the air guide plate should be raised to two positions.

[0092] When the indoor ambient temperature is between 5 and 10 degrees Celsius, the low indoor temperature has a significant impact on the airflow from the air outlet. In this case, the air guide plate should be adjusted to the minimum air guide angle.

[0093] When the indoor ambient temperature is below 5 degrees Celsius, the low indoor temperature has a significant impact on the airflow from the air outlet. At this time, adjust the air guide plate to the minimum air guide angle and adjust the indoor unit's fan speed to the maximum fan speed. You can also turn on the auxiliary heating mode at the same time.

[0094] 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.

[0095] According to the embedded air conditioner provided in the embodiments of the present invention, as the indoor ceiling height increases, the distance between the air outlet and the indoor floor or the user continuously increases, and the airflow from the air outlet needs to travel a longer distance to reach the user's area or blow onto the user. When the temperature difference between the indoor ambient temperature and the set temperature of the embedded air conditioner is large, the airflow from the air outlet needs to travel a longer heat exchange path before reaching the user's area or blowing onto the user. At this time, due to the longer heat exchange path and the larger heat exchange, the temperature of the airflow from the air outlet will change significantly. The large temperature difference between the airflow from the air outlet and the set temperature when it blows onto the user will cause discomfort to the user, reducing user comfort and user experience. According to the control method of the embedded air conditioner provided in the embodiments of the present invention, the airflow direction of the embedded air conditioner can be adjusted to the target airflow direction according to the indoor ceiling height and indoor ambient temperature. Moreover, along the target airflow direction, the heat exchange path length of the airflow from the air outlet is negatively correlated with the temperature difference between the indoor ambient temperature and the set temperature. When there is a large temperature difference between the indoor ambient temperature and the set temperature, adjust the air outlet direction to reduce the heat exchange path length between the air outlet and the indoor air, thereby reducing the temperature change of the air outlet.

[0096] As the temperature difference between the indoor environment and the set temperature increases, the heat exchange path length of the air outlet is shortened, reducing the heat exchange between the air outlet and the indoor air. This prevents the air with large temperature changes from blowing directly onto the user's area or onto the user, reducing user discomfort and improving the user experience.

[0097] 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.
