[0002] This application claims priority to and the benefit of the following patent applications, the entire contents of which are incorporated herein by reference:

[0003] A Chinese patent application entitled “Method for estimating indoor temperature, air conditioning system and computer storage medium”, application number 202310768447.2, submitted to the State Intellectual Property Office of China on June 27, 2023. Technical Field

[0004] The present application relates to the technical field of household appliances, and in particular to a method for estimating indoor temperature, an air-conditioning system, and a computer storage medium. Background Art

[0005] Air conditioning systems need to control their operation based on the indoor ambient temperature. Due to factors such as climate and building structure, some existing air conditioning systems, such as those in North America, place the air conditioner in the attic or basement of a building and run air ducts to deliver the cool or hot air generated by the air conditioner to the bedroom. Consequently, the air conditioner is located far from the bedroom, and the return air temperature deviates from the indoor temperature. Typically, these devices obtain the indoor temperature by acquiring the ambient temperature of a control device, such as a wired controller, located in the bedroom. However, many wired controllers and air conditioners currently on the market use wireless communication with the air conditioner via phone cards. Because communication between the wired controller and the air conditioner consumes data, the indoor temperature measured by the wired controller cannot be transmitted to the air conditioner in real time, resulting in a delay in obtaining the indoor temperature. Alternatively, communication between the wired controller and the air conditioner can be interrupted, leading to failure to obtain the indoor temperature.

[0006] Application Contents

The estimating method includes: obtaining a temperature compensation value; obtaining a first temperature of the environment in which the air conditioner is located based on the interruption of wireless communication between the air conditioner and the control device; and determining that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0009] According to the indoor temperature estimating method disclosed in the present invention, when the wireless communication connection between the control device and the air conditioner is interrupted, the first temperature of the environment in which the air conditioner is located plus the temperature compensation value is used as the estimated value of the indoor temperature, so as to provide a reference value of the indoor temperature for the operation of the air conditioner, thereby solving the problem of delayed or failed indoor temperature acquisition during communication interruption. Moreover, the estimated value of the indoor temperature is closer to the actual value of the indoor temperature relative to the first temperature of the environment in which the air conditioner is located, so that the operation of the air conditioner is closer to the actual needs of the user, and the accuracy of automatic control of the air conditioner operation is improved.

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0028] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain", and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0029] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0030] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "below" another element or feature would then be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein are interpreted accordingly.

[0031] As shown in FIG1 , according to an embodiment of the present disclosure, a method for estimating indoor temperature is proposed. The method is applied to an air conditioning system and provides the air conditioning system with an estimated indoor temperature value, thereby providing data support for the air conditioning system. This method solves the problem of the air conditioner being unable to obtain indoor temperature data or obtaining indoor temperature data with a delay when communication between the air conditioner and the control device is interrupted. Specifically, the method includes the following steps:

[0032] Step S101: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0033] Step S102: obtaining a temperature compensation value;

[0034] Step S103: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0035] In this embodiment, based on factors such as climate and building structure, the air conditioner and control device in the air conditioning system are located in different spaces. For example, the control device is typically placed in the bedroom for easy user operation, while the air conditioner is placed in an attic or basement, placing the air conditioner and control device at a distance. An air supply duct is provided between the air conditioner and the control device to deliver the cooled or heated air generated by the air conditioner to the bedroom. Because the air conditioner and control device are separated by a wall or other building structure, to facilitate the placement of the air conditioning system and save installation costs, such as by avoiding the need to drill holes in the wall and thread wires, a wireless communication connection is established between the control device and the air conditioner by inserting a phone card. This data transmission between the control device and the air conditioner is achieved by consuming billable data, allowing the user to issue control commands to the air conditioner by operating the control device in a space such as a bedroom to control its operation. In this embodiment, the control device includes, but is not limited to, a wired controller and a remote control.

[0036] It is understandable that since the air conditioner and the control equipment are respectively installed in different building spaces, there must be differences in the ambient temperature in different building spaces. In particular, when the air conditioner is in continuous operation, the air conditioner continuously supplies cold air or hot air to the bedroom through the air supply duct, which will cause the indoor temperature in the bedroom to be significantly different from the ambient temperature of the air conditioner.

[0037] When the wireless communication between the air conditioner and the control device is connected, the temperature of the environment where the control device is located is the indoor temperature. The temperature detected by the control device is transmitted to the air conditioner through wireless communication to provide indoor temperature data support for the operation of the air conditioner.

[0038] When the wireless communication connection between the air conditioner and the control device is interrupted, the ambient temperature in the bedroom detected by the control device cannot be transmitted to the air conditioner. At this time, according to the temperature difference between the environment in which the air conditioner is located and the environment in which the control device is located, a temperature compensation value is obtained. When the wireless communication connection between the air conditioner and the control device is interrupted, the first temperature of the environment in which the air conditioner is located is obtained. The first temperature can be the return air temperature detected at the return air outlet of the air conditioner, or it can be the ambient temperature detected by a temperature sensor arranged around or near the air conditioner. The sum of the first temperature and the temperature compensation value is used as the estimated value of the indoor temperature at this time. Real-time correction is performed based on the real-time temperature value of the air conditioner to obtain the real-time indoor temperature, so as to provide a reference value of the indoor temperature for the operation of the air conditioner, solve the problem of delay or failure in obtaining the indoor temperature during the communication process, and the estimated value of the indoor temperature is closer to the actual value of the indoor temperature than the first temperature of the environment in which the air conditioner is located, so that the operation of the air conditioner is closer to the actual needs of the user and the accuracy of the automatic control of the air conditioner operation is improved.

[0039] It should be noted that, in the present embodiment, there are multiple ways to obtain the temperature compensation value. For example, the temperature compensation value can be calculated based on the real-time temperature value of the environment in which the air conditioner is located and the temperature value of the environment in which the control device is located; or, the temperature compensation value can be calculated based on the historical record data of the ambient temperature of the air conditioner (such as the ambient temperature in the attic) and the ambient temperature of the control device (such as the ambient temperature in the bedroom). In the present embodiment, there is no specific limitation on the way to obtain the temperature compensation value.

[0040] As shown in FIG2 , according to some embodiments of the present disclosure, the inference method includes the following steps:

[0041] Step S201: acquiring in real time a second temperature of an environment in which the air conditioner is located and a third temperature of an environment in which the control device is located based on wireless communication between the air conditioner and the control device;

[0042] Step S202: Calculating a first difference between the third temperature and the second temperature;

[0043] Step S203: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0044] Step S204: obtaining the start time of the interruption of wireless communication between the air conditioner and the control device;

[0045] Step S205: determining the first difference at a moment before the starting moment as the temperature compensation value;

[0046] Step S206: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0047] In this embodiment, in step S201, when the wireless communication between the air conditioner and the control device remains connected, the second temperature data of the environment in which the air conditioner is located is obtained in real time, and the third temperature data of the environment in which the control device is located is obtained in real time, wherein the second temperature data is obtained by detecting by a first temperature sensor arranged at the return air outlet of the air conditioner, and the third temperature data is obtained by detecting by a second temperature sensor arranged in the control device.

[0048] In step S202, by calculating in real time the first difference between the third temperature and the second temperature, the temperature difference between the ambient temperature of the control device (such as the ambient temperature in the bedroom) and the ambient temperature of the air conditioner (such as the ambient temperature in the attic) can be obtained, and a data set of the first difference between the third temperature and the second temperature during the period when the wireless communication between the air conditioner and the control device remains connected can be obtained.

[0049] In steps S204 to S205, by obtaining the starting moment of the wireless communication interruption between the air conditioner and the controller, using the starting moment as the reference point of time, and determining the first difference at the moment immediately before the starting moment as the temperature compensation value, the determined temperature compensation value is made to be closest to the temperature difference value between the actual indoor temperature at the current moment (i.e., the ambient temperature in the bedroom) and the temperature at which the air conditioner is located, and has a relatively small error. In steps S203 and S206, when the wireless communication between the air conditioner and the control device is interrupted, the estimated indoor temperature can be obtained by adding the temperature compensation value to the first temperature detected in the environment where the air conditioner is located, making the calculated indoor temperature closer to the actual indoor temperature, so as to improve the control accuracy of the air conditioner during operation.

[0050] Among them, in this embodiment, the moment immediately before the starting moment refers to the moment with a time interval of t1 from the starting moment, and the value range of the time interval t1 is 0 < t1 < 10s. It can be understood that t1 can take a time value infinitely close to 0, ensuring that the temperature compensation value is the first difference calculated from the data of the third temperature and the second temperature transmitted most recently before the starting moment.

[0051] As shown in Figure 3, according to some embodiments of the present disclosure, the estimation method specifically includes the following steps:

[0052] Step S301: According to the wireless communication connection between the air conditioner and the control device, obtain the second temperature in the environment where the air conditioner is located and the third temperature in the environment where the control device is located in real time;

[0053] Step S302: Calculate the first difference obtained by subtracting the second temperature from the third temperature;

[0054] Step S303: According to the wireless communication interruption between the air conditioner and the control device, obtain the first temperature in the environment where the air conditioner is located;

[0055] Step S304: Obtain the starting moment of the wireless communication interruption between the air conditioner and the control device;

[0056] Step S305: Determine the first difference at the moment immediately before the starting moment as the temperature compensation value; Step S306: Determine the sum of the first temperature and the temperature compensation value as the indoor temperature;

[0057] Step S307: Obtain the first value of the indoor temperature at the starting moment;

[0058] Step S308: Obtain the second value of the indoor temperature in real time after the starting moment;

[0059] Step S309: Calculate the second difference obtained by subtracting the first value from the second value;

[0060] Step S310: Determine whether the absolute value of the second difference is greater than a first preset value. If so, assign the temperature compensation value to 0 and execute step S306. Otherwise, execute step S305.

[0061] In this embodiment, steps S301 to S306 are the same as steps S201 to S206 and are not described again herein.

[0062] In step S307, when the wireless communication connection between the air conditioner and the control device is interrupted, a first temperature of the air conditioner's environment at the start time is obtained, and a first value of the estimated indoor temperature at the start time is calculated based on the sum of the first temperature and the temperature compensation value. After the start time, in steps 308 to S309, a second value of the indoor temperature is obtained in real time, and a second difference is calculated by subtracting the first value from the second value. The absolute value of the second difference indicates the change in the estimated indoor temperature since the start time of the wireless communication interruption. The larger the absolute value of the second difference, the greater the change in the estimated indoor temperature.

[0063] In step S310, if the absolute value of the second difference is greater than the first preset value, it means that the current estimated indoor temperature is significantly different from the indoor temperature at the starting time. At this time, the ambient temperature of the air conditioner (i.e., the first temperature) changes greatly, and the accuracy of the second numerical value of the currently estimated indoor temperature is poor. Therefore, the temperature compensation value is assigned to 0, and the first temperature of the temperature environment in which the air conditioner is currently measured is taken as the indoor temperature for reference in the operation of the air conditioner.

[0064] If the absolute value of the second difference is less than or equal to the first preset value, it means that the current estimated indoor temperature is smaller than the indoor temperature at the starting moment. At this time, the ambient temperature of the air conditioner (i.e., the first temperature) changes less. It is determined that the second numerical value of the currently estimated indoor temperature is accurate. The temperature compensation value is still assigned according to the steps in step S304, that is, the temperature compensation value is assigned to the first difference before the starting moment, and the indoor temperature is estimated based on the sum of the temperature compensation value and the first temperature to obtain a more accurate estimated value of the indoor temperature.

[0065] In this embodiment, the first preset value a is in the range of 2°F≤a≤6°F. For example, the first preset value may be 2°F, 2.5°F, 3°F, 3.5°F, 4°F, etc.

[0066] As shown in FIG4 , according to some embodiments of the present disclosure, the inference method specifically includes the following steps:

[0067] Step S401: acquiring in real time a second temperature of an environment in which the air conditioner is located and a third temperature of an environment in which the control device is located based on wireless communication between the air conditioner and the control device;

[0068] Step S402: Calculating a first difference between the third temperature and the second temperature;

[0069] Step S403: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0070] Step S404: obtaining the start time of the interruption of wireless communication between the air conditioner and the control device;

[0071] Step S405: obtaining the interruption duration of the wireless communication between the air conditioner and the control device;

[0072] Step S406: Determine whether the interruption duration is greater than the first time setting value, if so, set the temperature compensation value to 0, otherwise, execute step S407;

[0073] Step S407: determining the first difference at a moment before the starting moment as the temperature compensation value;

[0074] Step S408: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0075] In this embodiment, steps S401 to S404 are the same as steps S201 to S204, and steps S407 to S408 are the same as steps S205 to S206, which are not described in detail here.

[0076] In steps S405 and S406, the duration of the wireless communication interruption is the duration of the wireless communication interruption between the air conditioner and the control device, starting from the start of the wireless communication interruption. The longer the interruption duration, the longer the wireless communication interruption. Since the air conditioner and the control device are located in different building spaces, affected by environmental factors and the air conditioner's own operating factors, when the duration of the wireless communication interruption is greater than the first time set value, it means that the ambient temperature of the space where the air conditioner is located (i.e., the first temperature) and the ambient temperature of the space where the control device is located (i.e., the actual value of the indoor temperature) vary significantly. As a result, when the temperature compensation value is assigned to the first difference, the estimated indoor temperature has significantly deviated from the actual value of the indoor temperature, resulting in poor accuracy of the estimated indoor temperature. Therefore, the temperature compensation value is assigned to 0, and when the wireless communication is interrupted, the first temperature of the environment where the air conditioner is located is used as the estimated indoor temperature.

[0077] When the interruption duration of the wireless communication interruption is less than or equal to the first time setting value, it means that the change between the ambient temperature of the space where the air conditioner is located (i.e., the first temperature) and the ambient temperature of the space where the control device is located (i.e., the actual value of the indoor temperature) is small, so that when the temperature compensation value is assigned to the first difference, the estimated indoor temperature is closer to the actual value of the indoor temperature, so the accuracy of the estimated indoor temperature is good. In the state of wireless communication interruption, the sum of the first temperature and the temperature compensation value is used as the value of the indoor temperature to ensure that the indoor temperature calculated according to the indoor temperature estimation method has high accuracy.

[0078] In some implementations, the first time setting value t2 has a value range of 0.5 hours ≤ t2 ≤ 1 hour. For example, the first time setting value can be set to 0.5 hours, 0.8 hours, 1 hour, etc.

[0079] In some implementations, the first time setting value t2 has a value range of 10 minutes ≤ t2 ≤ 30 minutes. For example, the first time setting value can be set to 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, etc.

[0080] In other embodiments, the value range of the first time setting value t2 is 1 hour ≤ t2 ≤ 24 hours. For example, the first time setting value can be set to 1 hour, 2 hours, 3 hours, 10 hours, 20 hours, etc.

[0081] It should be noted that the first time setting value can be adjusted according to different regions, different seasons, different building structure types, or different user habits. For example, in low-latitude areas close to the equator, the daily temperature difference is small, so the first time setting value can be set to a larger value, such as 10 hours, 15 hours, 20 hours, etc.; in spring or autumn in high-latitude areas, the temperature difference between day and night is large, and factors such as external ambient temperature changes and light also have a greater impact on the interior of the building structure. Therefore, the first time setting value can be set to a smaller value, such as 1 hour, 2 hours, 3 hours, 5 hours, etc.

[0082] According to some embodiments of the present disclosure, the inference method specifically includes the following steps:

[0083] Step S501: acquiring in real time a second temperature of an environment in which the air conditioner is located and a third temperature of an environment in which the control device is located based on wireless communication between the air conditioner and the control device;

[0084] Step S502: Calculating a first difference between the third temperature and the second temperature;

[0085] Step S503: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0086] Step S504: obtaining the start time of the interruption of wireless communication between the air conditioner and the control device;

[0087] Step S505: obtaining a first value T1 of the first temperature at the start time;

[0088] Step S506: obtaining a second value T2 of the first temperature at a first time t from the start time;

[0089] Step S507: Calculate the temperature change rate of the first temperature according to the formula (T2-T1) / t;

[0090] Step S508: determining whether the absolute value of the temperature change rate is greater than a second preset value, if so, setting the temperature compensation value to 0, otherwise executing step S509;

[0091] Step S509: determining the first difference at a moment before the starting moment as the temperature compensation value;

[0092] Step S510: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0093] In this embodiment, steps S501 to S504 are the same as steps S201 to S204, and steps S509 to S510 are the same as steps S205 to S206, which are not described in detail here.

[0094] In steps S505 to S508, after the wireless communication is interrupted, as the air conditioner continues to operate and continuously outputs cooling or heating to the bedroom, the ambient temperature of the environment in which the air conditioner is located and the ambient temperature of the environment in which the control device is located will change. In this process, the first value T1 of the first temperature of the environment in which the air conditioner is located at the starting time is first recorded, and the time interval t from the current time to the starting time (i.e., the first time) and the second value T2 of the first temperature of the environment in which the air conditioner is located at the current time are obtained. The formula (T2-T1) / t can calculate the temperature change rate of the first temperature of the room. If the absolute value of the temperature change rate of the first temperature is greater than the second preset value, it means that the change rate of the first temperature is large during the time period from the first time t to the starting time. If the estimated indoor temperature is still calculated based on the sum of the first difference and the first temperature, there will be a large error. Therefore, the temperature compensation value is assigned to 0. When the wireless communication is interrupted, the first temperature of the environment in which the air conditioner is located is used as the estimated indoor temperature.

[0095] If the absolute value of the temperature change rate of the first temperature is less than or equal to the second preset value, it means that the change rate of the first temperature is small during the time period from the first time t to the starting time, and the estimated indoor temperature based on the sum of the first difference and the first temperature is more accurate. Therefore, when the wireless communication is interrupted, the temperature compensation value is assigned to the first difference, and the sum of the first temperature and the temperature compensation value is used as the value of the indoor temperature to ensure that the indoor temperature calculated according to the indoor temperature estimation method has high accuracy.

[0096] According to some embodiments of the present disclosure, the inference method specifically includes the following steps:

[0097] Step S601: acquiring in real time a second temperature of an environment in which the air conditioner is located and a third temperature of an environment in which the control device is located based on wireless communication between the air conditioner and the control device;

[0098] Step S602: Calculating a first difference between the third temperature and the second temperature;

[0099] Step S603: acquiring a first temperature of an environment where the air conditioner is located according to the interruption of wireless communication between the air conditioner and the control device;

[0100] Step S604: recording mapping relationship data between the second temperature and the first difference within at least one operation cycle according to the second temperature and the first difference;

[0101] Step S605: Acquire a first mapping relationship of mapping relationship data in an operation cycle closest to the current moment;

[0102] Step S606: determining, according to the first mapping relationship, a first difference corresponding to the first temperature at the current moment as a temperature compensation value;

[0103] Step S607: Determine that the sum of the first temperature and the temperature compensation value is the indoor temperature.

[0104] In this embodiment, steps S601 to S602 are the same as steps S201 to S202, and steps S606 are the same as steps S206, which are not described in detail here.

[0105] In step S604, by recording the temperature data of the third temperature and the second temperature when the air conditioner and the control device are in a wireless communication connection state, a one-to-one mapping relationship data of the second temperature and the first difference value of at least one operating cycle can be obtained, wherein the operating cycle can be the operating time cycle of the air conditioning system, or the numerical change cycle of the second temperature.

[0106] In some embodiments, the operating cycle is set as the operating time cycle of the air-conditioning system. For example, the operating time cycle of the air-conditioning system is one day, that is, from 0:00 to 24:00. In this embodiment, the mapping relationship data between the second temperature and the first difference in at least one operating cycle is collected from 0:00 to 24:00 at least in one day, the third temperature, the second temperature and the first difference obtained by subtracting the second temperature from the third temperature at each moment are collected. The one-to-one correspondence between the second temperature and the first difference obtained based on the collected data is the mapping relationship data.

[0107] In some embodiments, the operating cycle is a cycle of value change of the second temperature. Since the value of the second temperature changes from low to high and then from high to bottom during the operation of the air-conditioning system, when the value of the second temperature rises from the lowest value to the highest value and then falls back to the lowest value, it is an operating cycle, or when the value of the second temperature drops from the highest value to the lowest value and then rises back to the highest value, it is an operating cycle. Data on the third temperature corresponding to each second temperature value and the first difference obtained by subtracting the second temperature from the third temperature are collected, and the one-to-one correspondence between the second temperature and the first difference obtained based on the collected data is the mapping relationship data.

[0108] It is understandable that if in one operation cycle, when the second temperature has the same value at different stages and corresponds to different first differences, the average value of the different first differences is taken as the data corresponding to the second temperature.

[0109] In steps S605 to S606, by obtaining the first mapping relationship of the mapping relationship data within the operating cycle closest to the current moment, the environmental factors in the obtained first mapping relationship are made closest to the state at the current moment to reduce the impact of the environmental factors on the estimation results, and the first difference corresponding to the first temperature at the current moment is determined according to the first mapping relationship, and the first difference is used as the temperature compensation value to reduce the error of the numerical value of the estimated indoor temperature.

[0110] According to an embodiment of the present disclosure, an air conditioning system is further proposed. As shown in FIG5 , the air conditioning system includes: an air conditioner 10 , a control device 20 and a control apparatus 30 .

[0111] The return air outlet of the air conditioner 10 is provided with a first temperature sensor 11, which is used to detect the first temperature of the air conditioner 10 and the control device 20 when the wireless communication is interrupted. The first temperature sensor 11 is also used to detect the second temperature of the air conditioner 10 and the control device 20 when the wireless communication is connected.

[0112] The control device 20 is provided with a second temperature sensor 21 , which is further used to detect a third temperature when the air conditioner 10 and the control device 20 are in wireless communication connection.

[0113] The control device 30 is provided in the air conditioner 10 and is communicatively connected with the air conditioner 10 and the control device 20 respectively. The control device 20 transmits the third temperature to the control device 30 by wireless communication. The control device 30 is used to obtain the temperature compensation value, obtain the first temperature according to the interruption of the wireless communication between the air conditioner 10 and the control device 20, and determine that the sum of the first temperature and the temperature compensation value is the indoor temperature, thereby calculating the specific value of the indoor temperature and providing data support for the operation of the air conditioner 10.
