[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 performance, like other air conditioners, is linked to compressor power, refrigerant, and heat dissipation.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0044] In related technologies, embedded air conditioners are generally suspended from the ceiling of a room, with temperature sensing elements located inside the embedded air conditioner. When the indoor height of the room is different, the indoor air circulation will be affected, and the ambient temperature detected by the temperature sensing element will still differ from the actual indoor temperature, which seriously affects the user experience.

[0045] The indoor unit of the embedded air conditioner provided in this embodiment of the invention is installed at the ceiling of the room. The indoor unit contains a temperature sensing element for detecting the indoor temperature. During operation, the indoor temperature detected by the sensing element is compared with the set temperature of the embedded air conditioner to jointly control its operation. For example, when the difference between the detected and set temperatures is large, the operating power of the embedded air conditioner needs to be maintained or increased to facilitate rapid heat exchange between the indoor air and the indoor unit, quickly stabilizing the indoor temperature to the set temperature and improving the user experience. When the difference is small, the operating frequency of the air conditioner needs to be reduced or the air conditioner can be stopped. This control logic is stored in the control module of the embedded air conditioner, enabling efficient and stable operation.

[0046] As indoor ceiling height changes, the airflow from the recessed air conditioner's vents experiences significant velocity reduction as it reaches the ground or other indoor locations further away, making it difficult for the vented air to circulate and exchange heat with the indoor air. Furthermore, as ceiling height increases and indoor space expands, indoor air temperature uniformity decreases. For example, with increased ceiling height, the hot air from the recessed air conditioner's vents only circulates with the indoor air near the vent, while the cold air first descends to the ground. The temperature sensing element then registers an indoor temperature closer to the vent's temperature than the temperature at lower levels of the room. This results in a significant difference between the perceived indoor temperature and the set temperature when the user is at the floor level, leading to a poor user experience.

[0047] 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 about the building structure, which can be directly input through the air conditioner's control panel or remote control.

[0048] 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 The control method for an embedded air conditioner includes the following steps:

[0049] S100: Obtain the indoor floor height and indoor temperature of the room where the embedded air conditioner is located.

[0050] S200: Adjust the indoor temperature to the indoor feedback temperature based on the influence of the indoor floor height on the indoor temperature, and control the operation of the embedded air conditioner based on the indoor feedback temperature and the set temperature of the embedded air conditioner.

[0051] In step S100, the indoor temperature is obtained through a temperature detection element. This indoor temperature is actually closer to the ambient temperature at the air outlet of the embedded air conditioner, and is also close to the set temperature of the embedded air conditioner, but differs significantly from the air temperature at lower locations in the room. The indoor floor height information can be obtained from user input or from the detection signal of a distance sensor.

[0052] In step S200, the indoor detected temperature is adjusted to the indoor feedback temperature based on the influence of the indoor ceiling height on the indoor detected temperature. It is understood that when the indoor ceiling height is low, the influence of the indoor ceiling height on the indoor detected temperature is small, and the indoor detected temperature may not be adjusted or may be adjusted only slightly. When the indoor ceiling height is high, the actual temperature at lower locations in the room differs significantly from the indoor detected temperature. In this case, the adjustment range of the indoor detected temperature needs to be appropriately increased to improve the experience for users at lower locations. It should be noted that in this embodiment of the invention, the embedded air conditioner does not need to be connected to additional temperature sensing elements, nor does it need to have temperature sensing elements installed at lower locations in the room; temperature information is obtained solely through the temperature sensing element installed at the indoor unit.

[0053] The indoor temperature is adjusted to the indoor feedback temperature based on the room's ceiling height. This feedback temperature takes into full account the impact of ceiling height on the temperature sensing element's acquisition of temperature information, providing a better reflection of the air temperature at lower locations in the room and more closely resembling the user's perceived temperature. By jointly controlling the operation of the embedded air conditioner using the indoor feedback temperature and the set temperature, the actual indoor temperature can be brought closer to the set temperature, improving the user experience.

[0054] According to the control method for an embedded air conditioner provided in this embodiment of the invention, the temperature sensing element and the indoor unit of the embedded air conditioner are installed at the top of the room. When the indoor ceiling height is large, the distance between the indoor temperature detected by the temperature sensing element and the indoor floor is large. Due to air circulation efficiency and the density of hot and cold air, there is a certain difference between the indoor temperature detected and the temperature at a lower location in the room. Based on the influence of the indoor ceiling height on the indoor temperature detected, the indoor temperature is adjusted to an indoor feedback temperature. The indoor feedback temperature is closer to the actual indoor temperature and can reflect the actual heat exchange situation of the indoor air. Then, the operation of the embedded air conditioner is controlled according to the indoor feedback temperature and the set temperature of the embedded air conditioner. By controlling the start-up, shutdown, and operating power of the air conditioner through the above steps, the influence of the indoor ceiling height on the indoor temperature detected can be mitigated or eliminated, allowing for sufficient indoor air circulation, improving the uniformity of indoor temperature, and enhancing the user experience.

[0055] In some embodiments, the step of adjusting the indoor detection temperature to the indoor feedback temperature based on the influence of indoor floor height on the indoor detection temperature specifically includes:

[0056] S210. Determine the temperature compensation coefficient based on the indoor floor height.

[0057] S220. Determine the indoor feedback temperature based on the temperature compensation coefficient and the indoor detection temperature.

[0058] In step S210, a temperature compensation coefficient is determined based on the influence of indoor floor height on the indoor detected temperature. The indoor feedback temperature can then be calculated using this temperature compensation coefficient and the indoor detected temperature. The temperature compensation coefficient can be obtained from historical data or calculated using an influence formula. For example, the temperature compensation coefficient decreases as the indoor floor height increases. In some cases, the indoor detected temperature obtained by the indoor unit's temperature sensing element is T1, and the actual indoor temperature is T2. A corresponding compensation relationship can be established between T2 and T1.

[0059] In one embodiment, the step of determining the temperature compensation coefficient based on the indoor floor height specifically includes:

[0060] S211. If the indoor floor height is less than or equal to the first height, then the temperature compensation coefficient is 1.

[0061] S212. If the indoor floor height is determined to be between the first height and the second height, then the first temperature compensation coefficient is determined according to the first influence formula.

[0062] S213. If the indoor floor height is determined to be greater than the second height, then the second temperature compensation coefficient is determined according to the second influence formula. The second temperature compensation coefficient is less than the first temperature compensation coefficient.

[0063] In step S211, when the indoor floor height is less than or equal to the first height, the indoor floor height is close to that of a normal room. At this time, the original control logic of the embedded air conditioner can be followed. The temperature compensation coefficient is 1, meaning that the indoor detected temperature is equal to the indoor feedback temperature. The air outlet of the air conditioner has a higher air circulation efficiency than the air at a lower position in the room, and the difference between the two is small, so there is no need to perform temperature compensation.

[0064] In step S212, when the indoor floor height is between the first height and the second height, the indoor floor height increases, and the air outlet of the embedded air conditioner is difficult to reach the lower position of the room. There is a certain difference between the actual indoor temperature and the set temperature. When the user is located on the indoor floor, he will be affected. Therefore, the first temperature compensation coefficient is determined by the first influence formula, and then the indoor feedback temperature is determined according to the first temperature compensation coefficient.

[0065] In step S213, when the indoor floor height is greater than the second height, the difference between the actual indoor temperature and the set temperature is larger, which will have a greater impact on the user located on the indoor floor. Therefore, a second temperature compensation coefficient is determined using the second influence formula, and then the indoor feedback temperature is determined based on the second temperature compensation coefficient. It should be noted that the compensation range of the second temperature compensation coefficient is greater than that of the first temperature compensation coefficient, which can make the actual indoor temperature adapt to the indoor floor height.

[0066] In some embodiments, the step of determining the temperature compensation coefficient based on the indoor floor height further includes, prior to:

[0067] S201. Obtain the operating mode of the embedded air conditioner.

[0068] S202. Determine the calculation parameters of the first and second influence formulas based on the operating mode.

[0069] In step S201, the operating modes include cooling mode, heating mode, and defrost mode. The impact of indoor ceiling height on the detected indoor temperature varies depending on the operating mode. In heating mode, the air outlet of the embedded air conditioner only circulates with the air near the outlet, therefore the indoor temperature detected by the temperature sensing element is higher than the temperature at lower indoor locations. Based on the impact of indoor ceiling height on the detected indoor temperature, the detected indoor temperature needs to be lowered to match the actual indoor temperature before being used in conjunction with the set temperature to control the air conditioner's operation. In cooling mode, the cold air blown out of the embedded air conditioner's outlet preferentially fills the space at lower indoor locations, therefore the indoor temperature detected by the temperature sensing element is higher than the temperature felt by the user at lower indoor locations. If efficient cooling continues, the user will feel cold. In this case, the indoor temperature detected by the temperature sensing element needs to be appropriately lowered to avoid excessively low temperatures at lower indoor locations, ensuring the indoor temperature feedback matches the actual indoor temperature before being used in conjunction with the set temperature to control the air conditioner's operation.

[0070] In step S202, the calculation parameters for the first and second influence formulas are determined based on the operating mode. When the indoor floor height is determined, the first influence formula and the second influence formula are different under different operating modes. Even when the operating mode is the same, the first influence formula and the second influence formula are different for different indoor floor heights.

[0071] In some embodiments, the step of determining the calculation parameters of the first influence formula and the second influence formula according to the operating mode specifically includes:

[0072] S2021. If the operating mode is determined to be heating mode, then the calculation parameter of the first influence formula is the first coefficient, and the calculation parameters of the second influence formula are the second coefficient and the third coefficient.

[0073] S2022. If the operating mode is determined to be cooling mode, then the calculation parameter of the first influence formula is the fourth coefficient, and the calculation parameters of the second influence formula are the fifth and sixth coefficients.

[0074] In step S2021, when the operating mode is heating mode, the calculation parameter of the first influence formula is the first coefficient, for example, 0.8. Indoor feedback temperature = 0.8 * indoor detected temperature. Lowering the temperature value detected by the temperature sensing element makes the indoor feedback temperature closer to the actual indoor temperature, thereby improving the user experience. Meanwhile, the second influence formula can be: Indoor feedback temperature = Indoor detected temperature * ab, where the second coefficient is a and the third coefficient is b; for example, indoor feedback temperature = indoor detected temperature * 0.8 - 1.

[0075] In step S2022, when the operating mode is cooling mode, the calculation parameter of the first influence formula is the fourth coefficient, for example, 0.9. Indoor feedback temperature = 0.9 * indoor detected temperature. Lowering the temperature value detected by the temperature sensing element makes the indoor feedback temperature closer to the actual indoor temperature, thereby improving the user experience. Meanwhile, the second influence formula can be: Indoor feedback temperature = indoor detected temperature * cd, with the fifth coefficient being c and the sixth coefficient being d; for example, indoor feedback temperature = indoor detected temperature * 0.8 - 2.

[0076] Based on steps S2021 and S2022, the first and second influence formulas for cooling or heating modes can be determined, thereby enabling precise compensation of indoor temperature under different indoor floor heights and different operating modes.

[0077] In some embodiments, the steps of adjusting the indoor detected temperature to an indoor feedback temperature based on the influence of indoor floor height on the indoor detected temperature, and controlling the operation of the embedded air conditioner based on the indoor feedback temperature and the set temperature of the embedded air conditioner, further include:

[0078] S300: After controlling the embedded air conditioner to run for a first preset time based on the indoor feedback temperature and the set temperature, obtain the measured temperature at the lowest position in the room.

[0079] S310: Correct the indoor feedback temperature based on the relationship between the measured temperature and the set temperature, and control the operation of the embedded air conditioner based on the corrected indoor feedback temperature and the set temperature.

[0080] In step S300, after the embedded air conditioner runs for a first preset time, such as 10 minutes, based on the indoor feedback temperature and the set temperature, the indoor air temperature tends to stabilize. The measured temperature at a lower location indoors is then obtained. This measured temperature reflects the final control result obtained according to the above control logic. The selection of the first preset time needs to ensure indoor temperature stability; it must be at least 5 minutes, but the interval cannot be too long, causing the indoor temperature to deviate for an extended period. The maximum interval is no more than 15 minutes.

[0081] In step S310, the control logic is checked and corrected by measuring the actual temperature. The indoor feedback temperature is corrected according to the relationship between the measured temperature and the set temperature. When the difference between the measured temperature and the set temperature is small, the indoor feedback temperature can be left unadjusted or adjusted slightly. When the difference between the measured temperature and the set temperature is large, the indoor feedback temperature needs to be adjusted significantly so that the actual room temperature control result is compatible with the set temperature.

[0082] In some embodiments, the step of correcting the indoor feedback temperature based on the relationship between the measured temperature and the set temperature specifically includes:

[0083] S311. If the difference between the measured temperature and the set temperature is less than or equal to the first temperature threshold, then maintain the original indoor feedback temperature.

[0084] S312. If the difference between the measured temperature and the set temperature is determined to be between the first temperature threshold and the second temperature threshold, then the seventh compensation coefficient is determined based on the difference, and the indoor feedback temperature is corrected based on the seventh compensation coefficient.

[0085] S313. If the difference between the measured temperature and the set temperature is greater than the second temperature threshold, then replace the indoor feedback temperature with the measured temperature.

[0086] In step S311, when the difference between the measured temperature and the indoor feedback temperature is less than or equal to the first temperature threshold, it indicates that the operation of the embedded air conditioner is relatively ideal, the set temperature can be achieved, and the user experience is better. At this time, there is no need to correct the indoor feedback temperature.

[0087] In step S312, if the difference between the measured temperature and the set temperature is between the first temperature threshold and the second temperature threshold, it indicates that there is still a certain deviation between the actual indoor temperature and the set temperature. The original indoor feedback temperature is insufficient to adjust the actual indoor temperature to the set temperature, and the indoor feedback temperature needs to be corrected again. It should be noted that the seventh compensation coefficient is determined based on the difference between the measured temperature and the set temperature. The seventh compensation coefficient can be positive or negative, and it can bring the actual indoor temperature closer to the set temperature.

[0088] In step S313, when the difference between the measured temperature and the set temperature is greater than the second temperature threshold, the deviation between the measured temperature and the set temperature is large. The measured temperature is directly replaced with the indoor feedback temperature, and the embedded air conditioner is controlled to operate based on the measured temperature and the set temperature.

[0089] In some embodiments, the step of obtaining the measured temperature at a lower indoor location specifically includes:

[0090] S301. Adjust the indoor fan of the embedded air conditioner to high fan speed mode and run for the second preset time.

[0091] S302. The indoor circulating temperature is detected by a temperature sensing element, and the actual temperature is determined based on the indoor circulating temperature.

[0092] The embedded air conditioner provided in this embodiment of the invention only has a temperature detection element at the indoor unit. Therefore, to obtain the actual indoor temperature, it is necessary to circulate the air from a lower position in the room to the indoor unit for detection. In step S301, the indoor fan of the embedded air conditioner is adjusted to a high-speed mode and runs for a second preset time, such as 3 minutes. During this time, the air from a lower position in the room flows to the indoor unit at a high speed. The temperature value obtained by the temperature detection element is the indoor circulating temperature, which is close to the actual measured temperature. The indoor circulating temperature can be appropriately corrected before use, resulting in high reliability.

[0093] In some embodiments, the step of adjusting the indoor detected temperature to the indoor feedback temperature based on the influence of indoor floor height on the indoor detected temperature further includes:

[0094] S400 controls multiple air guide vanes of the embedded air conditioner to have different swing angles at the same time, and the swing angles of the multiple air guide vanes relative to the center of the embedded air conditioner at the same time are successively different by a predetermined angle.

[0095] The embedded air conditioner includes multiple air outlets, each equipped with a guide vane. To ensure uniform airflow, the air outlets are symmetrically positioned. In step S400, the oscillating motion of the guide vanes causes the airflow from the air conditioner to circulate, improving the air delivery effect and enhancing the uniformity of indoor airflow and temperature control. There are no variations in the size of the airflow distribution, resulting in greater user comfort. Furthermore, because the oscillation angles of each guide vane are different, the overall opening of the air outlets is balanced, reducing airflow noise and creating a more stable noise level, thus minimizing noise pollution.

[0096] An embedded air conditioner according to a second aspect embodiment of the present invention executes a control method for an embedded air conditioner according to a first aspect embodiment of the present invention during operation.

[0097] According to the embedded air conditioner provided in this embodiment of the invention, the temperature sensing element and the indoor unit of the embedded air conditioner are installed at the top of the room. When the indoor ceiling height is large, the distance between the indoor temperature detected by the temperature sensing element and the indoor floor is large. Due to air circulation efficiency and the density of hot and cold air, there is a certain difference between the indoor detected temperature and the temperature at a lower location in the room. Based on the influence of the indoor ceiling height on the indoor detected temperature, the indoor detected temperature is adjusted to an indoor feedback temperature. The indoor feedback temperature is closer to the actual indoor temperature and can reflect the actual heat exchange situation of the indoor air. Then, the operation of the embedded air conditioner is controlled according to the indoor feedback temperature and the set temperature of the embedded air conditioner. By controlling the start-up, shutdown, and operating power of the air conditioner through the above steps, the influence of the indoor ceiling height on the indoor detected temperature can be mitigated or eliminated, allowing for sufficient indoor air circulation, improving the uniformity of indoor temperature, and enhancing the user experience.

[0098] 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.
