[0059] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0060] like Figure 1 As shown, according to a first aspect of an embodiment of the present application, a detection method for an air conditioner is proposed, comprising:

[0061] Step 101: In response to the heating belt start instruction, obtain the first temperature information of the compressor. It is understandable that the first temperature information can be collected and obtained through a temperature sensor, and in the air conditioner control process, it is usually necessary to collect the temperature information of the compressor to control the air conditioner. Therefore, the detection method of the present application can rely on the original temperature sensor on the air conditioner to collect the first temperature information. In the case where the air conditioner is not originally equipped with a temperature sensor, it is only necessary to install a temperature sensor on the compressor to collect the first temperature information. It is understandable that the first temperature information is the temperature of the compressor when the heating belt is just started. In this case, if the air conditioner is equipped with a heating belt, then the heating belt is in the initial stage of startup, and the temperature of the heating belt has little effect on the first temperature information. If the air conditioner is not equipped with a heating belt, then the first temperature information of the compressor will not be affected by the heating belt.

[0062] Step 102: After the first duration of the response to the heating belt start instruction, obtain the second temperature information of the compressor. It is understandable that the second temperature information and the first temperature information can be collected by the same temperature sensor, and the second temperature information and the first temperature information should be the temperature at the same location of the compressor. It is understandable that if the air conditioner is equipped with a heating belt, then as the heating belt runs for longer than the first duration, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor will rise. In this case, the second temperature information will be greater than the first temperature information. In the case where the compressor is not equipped with a heating belt, the temperature of the compressor will not be affected by the heating of the heating belt, and the second temperature information should be close to the first temperature information.

[0063] Step 103: Obtain a first state of the compressor when the first temperature information is obtained, and a second state of the compressor when the second temperature information is obtained. Considering that the heater belt activation instruction may be a control instruction automatically generated by the air conditioner or a control instruction issued by the user, the heater belt may be activated under different compressor states. If the first state of the compressor when the first temperature information is collected is different from the second state of the compressor when the second temperature information is collected, the operating temperature of the compressor may affect the comparison result of the first temperature information and the second temperature information, resulting in an inaccurate heater belt state. It is understood that the compressor state includes an activated state and a stopped state.

[0064] Step 104: When the first state and the second state are the same, the state of the heating zone of the air conditioner is determined based on the comparison result of the first temperature information and the second temperature information. When the first state and the second state are the same, it means that the first temperature information and the second temperature information were collected when the compressor was in the same operating state. The state of the heating zone of the air conditioner can be determined by comparing the first temperature information and the second temperature information. This makes it possible to determine the state of the heating zone without relying on the collection of current signals, without the need for an additional current collection device on the air conditioner, and without changing the electric control current of the air conditioner. Instead, the state of the heating zone is determined by collecting the temperature information of the compressor and further comparing the information, which can significantly reduce the cost of the air conditioner.

[0065] The detection method for an air conditioner provided in an embodiment of the present application takes into account that when the air conditioner is equipped with a heating belt to heat the compressor to prevent the compressor temperature from being too low, the heat energy generated by the heating belt will diffuse to the compressor, and the temperature of the compressor will increase with the length of time the heating belt is turned on; when the air conditioner is not equipped with a compressor, the compressor is outdoors, the temperature of the compressor will be close to the outdoor ambient temperature, and the temperature of the compressor will not change; on this basis, the present application collects the first temperature information of the compressor in response to the heating belt start-up instruction. In the case of the first temperature information, the heating belt is in the initial stage of startup. In this case, the heating temperature of the heating belt has little effect on the temperature of the compressor, that is, the first temperature should be close to the outdoor ambient temperature; after the first period of time in response to the heating belt start-up instruction, the second temperature information of the compressor is collected. In this case, if the air conditioner is equipped with a heating belt, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor should rise. If the air conditioner is not equipped with a heating belt, the second temperature information should also be close to or equal to the outdoor ambient temperature. After obtaining the first temperature information and the second temperature information, the state of the heating belt can be determined based on the comparison structure of the two, so that the determination of the state of the heating belt does not need to rely on the collection of current signals, there is no need to install an additional current collection device on the air conditioner, and there is no need to change the air conditioner's electronic control current. Instead, the state of the heating belt is determined by collecting the temperature information of the compressor and comparing the information, which can greatly reduce the cost of the air conditioner.

[0066] It is understandable that during the sales and use of air conditioners, the heating belt is an optional accessory. For the same air conditioner, the user may or may not purchase the heating belt. Each air conditioner can only have one set of electrical indicators. In order to avoid the actual operating power of the air conditioner being higher than the calibrated rated power of the air conditioner, the total power of the air conditioner when equipped with the heating belt can be used as the rated power. Therefore, when the air conditioner is not equipped with a heating belt, there may be a situation where the electrical indicators of the actual operation of the air conditioner do not correspond to the calibrated indicators of the air conditioner. This situation brings trouble to after-sales maintenance personnel. After-sales maintenance personnel cannot know whether the inaccurate power statistics of the air conditioner are caused by the heating belt. The control method provided in the embodiment of the present application can judge the status of the heating belt, which is beneficial for after-sales personnel to troubleshoot air conditioner failures.

[0067] It can be understood that the heating belt of the air conditioner is an optional component. Through the control method provided in the embodiment of the present application, the air conditioner does not need to perform circuit design due to whether it is equipped with a heating belt. For example, the air conditioner can be designed to be equipped with a heating belt as needed. Regardless of whether it is equipped with a heating belt, the air conditioner will generate a heating belt start-up instruction when the outdoor ambient temperature is lower than the threshold. When the heating belt is equipped, the heating belt can enter the working state. When the heating belt is not equipped, the air conditioner does not have an object to respond to the heating belt start-up instruction, but it will not hinder the normal operation of the air conditioner. The air conditioner can work normally regardless of whether it is equipped with a heating belt.

[0068] In some examples, the value of the first duration can be greater than or equal to 1 hour. When the heating belt operates for more than 1 hour, the heating belt will significantly improve the temperature of the compressor, so that the difference between the first temperature information and the second temperature information is obvious, which makes it easier to determine the status of the heating belt based on the comparison results of the two.

[0069] In some examples, the heating belt start-up command is generated when the compressor is shut down for more than a second period of time and the ambient temperature of the compressor is lower than a first threshold; and / or the heating belt start-up command is generated when the compressor is powered on for the first time and the ambient temperature of the compressor is lower than a first threshold.

[0070] After the compressor has been shut down for more than the second time period, it can be considered that the heat energy generated by the compressor during operation has been dissipated, and the temperature of the compressor will approach the ambient temperature. In this case, when the ambient temperature is lower than the first threshold, a heating belt start-up instruction can be generated to heat the compressor, so that when the air conditioner enters the working state, the response efficiency of the compressor is improved and the service life of the compressor is increased.

[0071] When the compressor is in the initial power-on state, it means that the air conditioner is a newly purchased air conditioner or a newly put into use air conditioner. Regardless of whether the air conditioner is equipped with a heating belt, the residual temperature of the heating belt will not affect the temperature of the compressor. Similarly, the compressor has not worked and the compressor will not have residual temperature. In this case, when the ambient temperature is lower than the first threshold, a heating belt start-up instruction can be generated to heat the compressor, so that when the air conditioner enters the working state, the response efficiency of the compressor is improved and the service life of the compressor is increased.

[0072] In some examples, the value of the second duration should be greater than 1 hour, and the value of the first threshold should be less than or equal to 1°C.

[0073] In some examples, the value of the second duration is negatively correlated with the ambient temperature information; the value of the first duration is positively correlated with the ambient temperature information.

[0074] It can be understood that the temperature sensor can be arranged on the outdoor unit of the air conditioner to collect the ambient temperature to obtain the ambient temperature information, and the lower the ambient temperature information, the lower the outdoor ambient temperature. In this case, after the compressor works for a long time, the speed of the compressor waste heat dissipation is faster, so the lower the ambient temperature information, the smaller the second time length value, and vice versa. Based on the same reason, the lower the outdoor ambient temperature, the lower the efficiency of the heating belt for the compressor temperature rise. In order to make the air conditioner equipped with the heating belt, the difference between the first temperature information and the second temperature information is more obvious, and the heating belt state is convenient for judging, the value of the first time length should be larger, and vice versa. The value of the first time length should be smaller.

[0075] In some examples, the first temperature information and the second temperature information are the exhaust temperature of the compressor.

[0076] The first temperature information and the second temperature information are both the exhaust temperature of the compressor, which is convenient for collecting temperature information.

[0077] As shown in Figure 7 and Figure 8 , the arrow direction in Figure 7 and Figure 8 is the heat supply direction of the heating belt 702. In the case of assembling the heating belt 702 on the compressor 701, the heat of the heating belt 702 will not only be supplied to the compressor 701, but also will spread along the shell of the compressor 701 to the exhaust port of the compressor 701. Therefore, collecting the exhaust temperature of the compressor 701 can determine whether the heating belt 702 is assembled on the compressor 701, and the exhaust temperature of the compressor 701 is convenient to collect, and it is convenient to set a temperature sensor at the exhaust port of the compressor 701.

[0078] As shown in Figure 3 , the relationship between the temperature of the compressor and the working time when the heating belt is assembled on the compressor is shown. According to the formula of heat absorption (or release) of matter:

[0079] Q=cmΔT

[0080] Where Q is the heat absorbed (or released); c is the specific heat capacity of the material; m is the mass of the object; ΔT is the change of temperature after heat absorption. When the copper pipe receives heat, the temperature sensor installed at the exhaust outlet of the compressor can detect the change of the copper pipe temperature, that is, the exhaust temperature of the compressor rises.

[0081] The results are shown in Figure 3As shown in the figure, when the outdoor ambient temperature is low, after the electric heater is turned on, the compressor exhaust temperature Tp0 increases over time as analyzed. After one hour of heating, Tp0 temperature increases by 4.1°C; after nearly two hours of heating, Tp temperature increases by 6.6°C.

[0082] in, Figure 3 The relationship between the heating belt power and time is also shown in FIG. Figure 3 The heating belt shown can operate at a constant power to make the air conditioner control more convenient and accurate, so that the state of the heating belt can be determined more accurately.

[0083] In some examples, based on the comparison result of the first temperature information and the second temperature information, the status of the heating belt of the air conditioner is determined, including: when the difference between the second temperature information and the first temperature information is greater than or equal to a second threshold, determining that the heating belt of the air conditioner is in an installed state; when the difference between the second temperature information and the first temperature information is less than the second threshold, determining that the heating belt of the air conditioner is in an uninstalled state.

[0084] When the difference between the second temperature information and the first temperature information is greater than or equal to the second threshold, it means that the second temperature information is higher than the first temperature information, which means that the heating belt is working and the temperature of the compressor increases. In this case, it can be considered that the air conditioner is equipped with a heating belt.

[0085] When the difference between the second temperature information and the first temperature information is less than the second threshold, it means that the second temperature information is close to the first temperature information, the second temperature information has not increased, and the compressor has not been heated. In this case, it is judged that the heating belt of the air conditioner is not installed.

[0086] It is understandable that when the heating belt is not installed, it may mean that the air conditioner is not equipped with a heating belt, or the heating belt may be damaged and cannot work normally.

[0087] In some examples, the second threshold value may be greater than or equal to 2°C and less than or equal to 8°C.

[0088] In some examples, the detection method further includes: calculating the total power of the air conditioner based on the operating power of the heating belt when the heating belt is installed.

[0089] When it is clear that the state of the heating belt is the installation state, the total power of the air conditioner is counted based on the operating power of the heating belt, so that the total power statistics of the air conditioner are more accurate, which is conducive to improving user experience.

[0090] In some examples, the detection method also includes: when the heating belt is not installed, obtaining the rated power of the air conditioner and the actual power of the air conditioner; obtaining the difference between the rated power and the actual power; when the difference between the difference and the operating power of the heating belt is less than a third threshold, determining that the air conditioner is in a normal state; when the difference between the difference and the operating power is greater than or equal to the third threshold, determining that the air conditioner is in an abnormal state.

[0091] Taking into account that the heating belt is an optional accessory of the air conditioner, during the sales process of the air conditioner, two calibration electrical parameters are usually not set depending on whether it is equipped with a heating belt. At the same time, in order to avoid the actual operating power of the air conditioner exceeding the rated operating power of the air conditioner, the power of the heating belt is usually included in the rated operating power statistics. Therefore, when the air conditioner is not equipped with a heating belt, the actual operating power of the air conditioner will be slightly lower than the rated power calibrated in the air conditioner manual. When the air conditioner fails, this power difference will cause great trouble to the maintenance personnel and make it difficult to determine the fault of the air conditioner.

[0092] If the heater belt is not installed, the difference between the rated power and the actual power is obtained. If the difference is less than a third threshold, the air conditioner is in a normal state and the power difference is caused by the operating power of the heater belt. If the difference is greater than or equal to the third threshold, the difference between the actual power and the rated power of the air conditioner is too large. In this case, the power difference is not caused by the operating power of the heater belt, and the air conditioner is abnormal. This setting can eliminate the influence of the heater belt power on the judgment of the air conditioner fault status, making air conditioner maintenance more convenient. At the same time, if the user discovers a deviation between the actual power and the rated power of the air conditioner, they can also determine whether the air conditioner is in a faulty state, avoiding frequent maintenance of the air conditioner and improving the user experience.

[0093] It can be understood that the third threshold is related to the operating power of the heating belt. The greater the operating power of the heating belt, the greater the value of the third threshold, and the lower the operating power of the heating belt, the smaller the value of the third threshold.

[0094] like Figure 2 As shown, in some examples, the detection method further includes:

[0095] Step 201: Determine whether the compressor shutdown time exceeds the second time period, or whether the compressor is started for the first time. If yes, execute step 202; otherwise, execute step 201.

[0096] Step 202: Determine whether the outdoor ambient temperature is less than a first threshold, if so, execute step 203, if not, execute step 202;

[0097] Step 203: Generate a heating belt start instruction and obtain first temperature information of the compressor when the heating belt is turned on;

[0098] Step 204: After the first time period in response to the heating belt start instruction, obtaining second temperature information of the compressor;

[0099] Step 205: Determine whether the difference between the second temperature information and the first temperature information is less than a second threshold, if yes, execute step 206, if no, execute step 205;

[0100] Step 206: Determine whether the heating belt of the air conditioner is not installed.

[0101] The detection method for an air conditioner provided in an embodiment of the present application takes into account that when the air conditioner is equipped with a heating belt to heat the compressor to prevent the compressor temperature from being too low, the heat energy generated by the heating belt will diffuse to the compressor, and the temperature of the compressor will increase with the length of time the heating belt is turned on; when the air conditioner is not equipped with a compressor, the compressor is outdoors, the temperature of the compressor will be close to the outdoor ambient temperature, and the temperature of the compressor will not change; on this basis, the present application collects the first temperature information of the compressor in response to the heating belt start-up instruction. In the case of the first temperature information, the heating belt is in the initial stage of startup. In this case, the heating temperature of the heating belt has little effect on the temperature of the compressor, that is, the first temperature should be close to the outdoor ambient temperature; after the first period of time in response to the heating belt start-up instruction, the second temperature information of the compressor is collected. In this case, if the air conditioner is equipped with a heating belt, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor should rise. If the air conditioner is not equipped with a heating belt, the second temperature information should also be close to or equal to the outdoor ambient temperature. After obtaining the first temperature information and the second temperature information, the state of the heating belt can be determined based on the comparison structure of the two, so that the determination of the state of the heating belt does not need to rely on the collection of current signals, there is no need to install an additional current collection device on the air conditioner, and there is no need to change the air conditioner's electronic control current. Instead, the state of the heating belt is determined by collecting the temperature information of the compressor and comparing the information, which can greatly reduce the cost of the air conditioner.

[0102] like Figure 4 As shown, according to the second aspect of the embodiment of the present application, a computer-readable storage medium 401 is proposed, and the computer-readable storage medium 401 stores a computer program 402 to implement the air conditioner detection method as any of the above technical solutions.

[0103] The computer-readable storage medium 401 provided in the embodiment of the present application takes into account that when the air conditioner is equipped with a heating belt to heat the compressor to prevent the compressor temperature from being too low, the heat energy generated by the heating belt will diffuse to the compressor, and the temperature of the compressor will increase with the length of time the heating belt is turned on; when the air conditioner is not equipped with a compressor, the compressor is outdoors, the temperature of the compressor will be close to the outdoor ambient temperature, and the temperature of the compressor will not change; on this basis, the present application collects the first temperature information of the compressor in response to the heating belt start-up instruction. In the case of the first temperature information, the heating belt is in the initial stage of startup. In this case, the heating temperature of the heating belt has little effect on the temperature of the compressor, that is, the first temperature should be close to the outdoor ambient temperature; after the first length of time in response to the heating belt start-up instruction, the second temperature information of the compressor is collected. In this case, if the air conditioner is equipped with a heating belt, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor should rise. If the air conditioner is not equipped with a heating belt, the second temperature information should also be close to or equal to the outdoor ambient temperature. After obtaining the first temperature information and the second temperature information, the state of the heating belt can be determined based on the comparison structure of the two, so that the determination of the state of the heating belt does not need to rely on the collection of current signals, there is no need to install an additional current collection device on the air conditioner, and there is no need to change the air conditioner's electronic control current. Instead, the state of the heating belt is determined by collecting the temperature information of the compressor and comparing the information, which can greatly reduce the cost of the air conditioner.

[0104] It is understandable that the first temperature information can be acquired through a temperature sensor, and during the air conditioner control process, it is usually necessary to acquire the temperature information of the compressor in order to control the air conditioner. Therefore, the detection method of the present application can rely on the original temperature sensor on the air conditioner to acquire the first temperature information. In the case where the air conditioner is not originally provided with a temperature sensor, it is only necessary to assemble a temperature sensor on the compressor to acquire the first temperature information. It is understandable that if the air conditioner is equipped with a heating belt, then the heating belt is in the initial stage of startup, and the temperature of the heating belt has little effect on the first temperature information. If the air conditioner is not equipped with a heating belt, then the first temperature information of the compressor will not be affected by the heating belt.

[0105] It is understandable that if the air conditioner is equipped with a heating belt, then as the running time of the heating belt exceeds the first time, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor will rise. In this case, the second temperature information will be greater than the first temperature information. If the compressor is not equipped with a heating belt, the temperature of the compressor will not be affected by the heating of the heating belt, and the second temperature information should be close to the first temperature information.

[0106] Based on such understanding, the technical scheme of the present application can be embodied in the form of a software product, which can be stored in a nonvolatile storage medium (which can be a CD-ROM, a U disk, a mobile hard disk, etc.), and includes a plurality of instructions to make a computer device (which can be a personal computer, a server, or a network device, etc.) execute the method of various implementation scenarios of the present application.

[0107] As shown in the third aspect of the embodiments of the present application, a control system is provided, comprising: a collection module 501, the collection module 501 is configured to acquire first temperature information of a compressor in response to a heating band start instruction; the collection module 501 is further configured to acquire second temperature information of the compressor after a first time length of the heating band start instruction; a state recognition module 502, the state recognition module 502 is configured to acquire a first state of the compressor when the first temperature information is acquired and a second state of the compressor when the second temperature information is acquired; and a determination module 503, the determination module 503 is configured to determine a heating band state of an air conditioner based on a comparison result of the first temperature information and the second temperature information in a case where the first state is the same as the second state. Figure 5 The control system provided by the embodiments of the present application considers that in a case where the air conditioner is provided with a heating band to heat the compressor to prevent the temperature of the compressor from being too low, the heat energy generated by the heating band will diffuse to the compressor, and the temperature of the compressor will rise with the opening time length of the heating band; in a case where the air conditioner is not provided with a compressor, the compressor is outdoor, and the temperature of the compressor will approach the outdoor environment temperature, and the temperature of the compressor will not change; on this basis, the present application acquires first temperature information of the compressor in response to a heating band start instruction, in the case of the first temperature information, the heating band is in the initial stage of starting, in this case, the heating temperature of the heating band has little effect on the temperature of the compressor, and the first temperature should approach the outdoor environment temperature; after a first time length of the heating band start instruction, the second temperature information of the compressor is acquired again, in this case, if the air conditioner is provided with a heating band, the heating effect of the heating band will be reflected on the compressor, and the temperature of the compressor should rise, if the air conditioner is not provided with a heating band, the second temperature information should also approach or equal to the outdoor environment temperature. After the first temperature information and the second temperature information are acquired, the state of the heating band can be determined based on the comparison structure of the two, so that the determination of the heating band state does not need to rely on the acquisition of the current signal, does not need to additionally carry a current acquisition device on the air conditioner, and does not need to change the current of the air conditioner, but determines the state of the heating band through the acquisition of the temperature information of the compressor and through the comparison of the information, which can greatly reduce the cost of the air conditioner.

[0108]

[0109] ​It can be understood that the acquisition module 501 can acquire the first temperature information through the temperature sensor, and the temperature information of the compressor is usually needed to be acquired in the control process of the air conditioner to control the air conditioner, so the detection method of the application can rely on the original temperature sensor on the air conditioner to acquire the first temperature information, and in the case that the air conditioner does not originally set the temperature sensor, only need to assemble the temperature sensor on the compressor to acquire the first temperature information. It can be understood that if the air conditioner is equipped with a heating belt, the temperature of the heating belt has little effect on the first temperature information when the heating belt is not started or in the initial stage of starting, and if the air conditioner is not equipped with a heating belt, the first temperature information of the compressor will not be affected by the heating belt.

[0110] It can be understood that if the air conditioner is equipped with a heating belt, as the running time of the heating belt exceeds the first time, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor will rise. In this case, the second temperature information will be greater than the first temperature information, and in the case that the compressor is not equipped with a heating belt, the temperature of the compressor will not be affected by the heating of the heating belt, and the second temperature information should be close to the first temperature information.

[0111] As shown in Figure 6 According to the fourth aspect of the embodiment of the application, a control device is provided, comprising: a memory 601 storing a computer program; a processor 602 executing the computer program; wherein the processor 602 implements the detection method of the air conditioner of any of the technical solutions when executing the computer program.

[0112] The control device provided by the embodiments of the present application considers that, in the case that the air conditioner is provided with a heating belt to heat the compressor to prevent the temperature of the compressor from being too low, the heat energy generated by the heating belt will diffuse to the compressor, and the temperature of the compressor will increase with the length of time that the heating belt is turned on; in the case that the air conditioner is not provided with a compressor, the compressor is located outdoors, and the temperature of the compressor will approach the outdoor ambient temperature, and the temperature of the compressor will not change; on this basis, the first temperature information of the compressor is collected in response to the heating belt starting instruction; in the case of the first temperature information, the heating belt is in the initial stage of starting, and in this case, the heating temperature of the heating belt has little effect on the temperature of the compressor, and the first temperature should approach the outdoor ambient temperature; after the first length of time in response to the heating belt starting instruction, the second temperature information of the compressor is collected; in this case, if the air conditioner is provided with a heating belt, the heating effect of the heating belt will be reflected on the compressor, and the temperature of the compressor should increase; if the air conditioner is not provided with a heating belt, the second temperature information should also approach or equal to the outdoor ambient temperature. After the first temperature information and the second temperature information are obtained, the state of the heating belt can be determined based on the comparison of the two, so that the determination of the state of the heating belt does not need to rely on the collection of the current signal, does not need to additionally carry a current collection device on the air conditioner, and does not need to change the electric current of the air conditioner, but determines the state of the heating belt by collecting the temperature information of the compressor and comparing the information, which can greatly reduce the cost of the air conditioner.

[0113] It can be understood that the first temperature information can be collected by a temperature sensor, and the temperature information of the compressor is usually collected in the control process of the air conditioner to control the air conditioner, so that the detection method of the present application can rely on the original temperature sensor on the air conditioner to collect the first temperature information, and in the case that the air conditioner does not originally have a temperature sensor, only a temperature sensor needs to be installed on the compressor to collect the first temperature information. It can be understood that, if the air conditioner is provided with a heating belt, the heating belt is in the initial stage of starting, and the temperature of the heating belt has little effect on the first temperature information; if the air conditioner is not provided with a heating belt, the first temperature information of the compressor will not be affected by the heating belt.

[0114] It can be understood that, if the air conditioner is provided with a heating belt, the heating effect of the heating belt will be reflected on the compressor as the length of time that the heating belt operates exceeds the first length of time, and the temperature of the compressor will increase, in which case the second temperature information will be greater than the first temperature information; in the case that the compressor is not provided with a heating belt, the temperature of the compressor will not be affected by the heating of the heating belt, and the second temperature information should approach the first temperature information.
