Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioner control, and in particular to an air conditioner and a control method and device thereof. BACKGROUND

[0002] At present, the existing air conditioner has become a common household appliance, and with the increasing improvement of people's living standards, users have higher and higher requirements for the comfort of air conditioner use. Therefore, in addition to meeting the basic requirements of refrigeration, heating and air supply, today's air conditioners also need to meet the humidity adjustment of the user's indoor environment, such as the dehumidification mode for dehumidification possessed by some air conditioners. However, in actual operation, the current air conditioner in the refrigeration mode or dehumidification mode will make the temperature of the indoor heat exchanger lower than the dew point temperature of the indoor air, so that the water vapor in the indoor air is continuously condensed, and after a period of operation, the humidity of the indoor air will be very low, which is not what the user needs. Since most air conditioners do not have a humidification function, the indoor environment will eventually make the user feel dry and uncomfortable. When the air conditioner is in the heating mode, the temperature of the indoor heat exchanger will be higher than the dew point temperature of the air, and the water vapor in the air will not be condensed. After a period of operation, the humidity level of the indoor environment will also have a high probability of not meeting the user's needs, and the humidity may be too high, which will also make the user feel uncomfortable. It can be seen that the current air conditioner can only control the temperature or simply reduce the humidity, and the control mode is simple, which cannot meet the user's requirements for indoor temperature and humidity, resulting in poor user experience. SUMMARY

The target temperature and humidity double-control mode is a temperature and humidity double-control mode corresponding to the first temperature difference and the first humidity difference in a plurality of temperature and humidity double-control modes preset by the processing module. The temperature and humidity double-control mode corresponds to the first temperature difference and the first humidity difference satisfying different conditions one by one. The control module is configured to control the air conditioner to execute the target temperature and humidity double-control mode determined by the processing module.

[0008] In a third aspect, a control device of an air conditioner is provided, which comprises a memory, a processor, a bus and a communication interface.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0028] It should be noted that the words “exemplary” or “for example” in the embodiments of the present application are used to represent an example, illustration or description. Any embodiment or design scheme described as “exemplary” or “for example” in the embodiments of the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In fact, the words “exemplary” or “for example” are intended to present the relevant concept in a specific manner.

[0029] It should be noted that, in the embodiments of the present application, "of", "corresponding" and "relevant" can be used interchangeably, and it should be pointed out that the meanings expressed are consistent when the differences are not emphasized.

[0030] In order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, "first", "second" and the like are used to distinguish the same or similar items with basically the same functions and effects, and those skilled in the art can understand that "first", "second" and the like are not limited in number and execution order.

[0031] First, the technical terms involved in the present application are explained as follows.

[0032] Referring to Figure 1 As shown in the figure, at present, most air conditioners 01 include an indoor unit 11 and an outdoor unit 12; the indoor unit 11 includes an indoor heat exchanger 111 and an indoor fan 112, and the outdoor unit 12 includes a compressor 121, a four-way valve 122, an outdoor heat exchanger 123 and an outdoor fan 124.

[0033] Based on the above air conditioner 01, the technical terms involved in the present application are explained as follows:

[0034] Refrigeration mode or dehumidification mode: the first end 1 and the fourth end 4 of the four-way valve 122 are connected, and the second end 2 and the third end 3 are connected; the high-temperature and high-pressure condensate from the compressor 121 enters the outdoor heat exchanger 123 through the four-way valve to condense and release heat, and then the low-temperature condensate enters the indoor heat exchanger 111 to evaporate and absorb heat, and then the refrigerant returns to the compressor through the four-way valve to complete a cycle. In the whole process, the indoor fan 112 and the outdoor fan 124 work. In this mode, the indoor heat exchanger 111 acts as an evaporator, and the outdoor heat exchanger 123 acts as a condenser.

[0035] Heating mode: the first end 1 and the second end 2 of the four-way valve 122 are connected, and the third end 3 and the fourth end 4 are connected; the high-temperature and high-pressure condensate from the compressor 121 enters the indoor heat exchanger 111 through the four-way valve to condense and release heat, and then the low-temperature condensate enters the outdoor heat exchanger 123 to evaporate and absorb heat, and then the refrigerant returns to the compressor through the four-way valve to complete a cycle. In the whole process, the indoor fan 112 and the outdoor fan 124 work. In this mode, the indoor heat exchanger 111 acts as a condenser, and the outdoor heat exchanger 123 acts as an evaporator.

[0036] Air supply mode: the whole outdoor unit 12 stops working, and only the indoor fan 112 in the indoor unit 11 operates.

[0037] In addition, all the humidity in the present application refers to relative humidity.

[0038] At present, most air conditioners can only control the temperature of the indoor, and further can only carry out simple dehumidification treatment on the indoor, and cannot simultaneously control the temperature and humidity of the indoor according to the needs of the user, resulting in poor user experience.

[0039] In view of the above problems, with reference to Figure 2 The air conditioner 02 provided by the embodiment of the present application comprises a humidity sensor 22 arranged on an indoor unit 21 of the air conditioner 02 and used for detecting the humidity of an indoor corresponding to the air conditioner, a first temperature sensor 25 arranged on or near an indoor evaporator 211 in the indoor unit 21 and used for measuring the saturation temperature of the indoor evaporator 211, a second temperature sensor 24 arranged on the indoor unit 21 and used for detecting the temperature of the indoor, an indoor fan 212 arranged in the indoor unit 21, and a control device 23 of the air conditioner, which can control the air conditioner according to the operating parameters (including the data detected by various sensors) generated in the operation of the air conditioner 02; the control device can be the main control board of the air conditioner 02 itself or a chip integrated on the main control board.

[0040] Based on the above air conditioner, with reference to Figure 3 The embodiment of the present application provides an air conditioner control method, which is specifically applied to the control device of the air conditioner, and the method comprises the following steps: 301-305.

[0041] 301, receiving a user instruction.

[0042] In the user instruction, at least the indoor set temperature and the indoor set humidity are carried.

[0043] In the embodiment of the present application, the control device of the air conditioner can receive the key instruction generated by the key trigger of the user to the air conditioner itself or the remote control instruction generated by the user through the operation of the remote controller, so as to determine the indoor humidity and indoor temperature required by the user.

[0044] 302, obtaining the first indoor temperature and the first indoor humidity corresponding to the air conditioner.

[0045] In the embodiment of the present application, the indoor temperature and the indoor humidity of the indoor corresponding to the air conditioner can be detected by the sensor arranged on the air conditioner. For example, as shown in Figure 2As shown, the indoor humidity sensor 22 can detect the humidity of the indoor corresponding to the air conditioner, and the second temperature sensor 24 can detect the temperature of the indoor corresponding to the air conditioner; when the step 302 is executed, the control device of the air conditioner can obtain the humidity data and temperature data currently detected by the humidity sensor 22 and the second temperature sensor 24, and take them as the first indoor humidity and the first indoor temperature (the same for different indoor humidity and indoor temperature in the future) respectively.

[0046] 303, calculate the first temperature difference between the first indoor temperature and the indoor set temperature, and the first humidity difference between the first indoor humidity and the indoor set humidity.

[0047] Specifically, in the embodiment of the application, the temperature difference between A and B is the value of A-B, and the humidity difference between C and D is the value of C-D. For example, the first temperature difference is the difference between the first indoor temperature and the indoor set temperature, and the first humidity difference is the difference between the first indoor humidity and the indoor set humidity. The same is true for any temperature difference and humidity difference in the future.

[0048] 304, determine the target temperature and humidity double control mode according to the first temperature difference and the first humidity difference.

[0049] Among them, the target temperature and humidity double control mode is the temperature and humidity double control mode corresponding to the first temperature difference and the first humidity difference in the preset multiple temperature and humidity double control modes; the temperature and humidity double control mode corresponds to the first temperature difference and the first humidity difference that meets different conditions one by one.

[0050] The multiple preset temperature and humidity double control modes in the embodiment of the application can be based on the indoor set temperature and indoor set humidity carried in the instruction triggered by the user, and according to the difference between the actual indoor humidity and the indoor set humidity and the difference between the indoor temperature and the indoor set temperature, the different indoor environments are divided into multiple types, and the corresponding temperature and humidity double control mode is set for each type. For example, refer to Figure 4 As shown in the figure, in the rectangular coordinate, the abscissa axis represents the indoor temperature Tn, the ordinate axis represents the indoor humidity RHn, the origin of the abscissa axis is the indoor set temperature Ts, and the origin of the ordinate axis is the indoor set humidity RHs, Figure 4 The different indoor environments corresponding to each region, the difference range between the indoor humidity and the indoor set humidity and the difference range between the indoor temperature and the indoor set temperature corresponding to each region are shown in the following table 1:

[0051]

[0052]

[0053] Table 1

[0054] Wherein, m is the first temperature threshold, n is the second temperature threshold, x is the first humidity threshold, y is the second humidity threshold; wherein m, n, x and y are the error values that are allowed to consider that the temperature and humidity control of the air conditioner in the actual indoor environment cannot completely reach the exact value required by the user, so Figure 4 The indoor environment corresponding to the E zone should be the indoor environment corresponding to the indoor set temperature and indoor set humidity set by the user. When the air conditioner is controlled, it is required to make the indoor environment caused by its operation to be the indoor environment corresponding to the E zone or close to the indoor environment corresponding to the E zone. Exemplarily, m can be -5℃ (only an example, other values less than zero can also be taken, which is specific according to the actual situation), n can be 5℃ (only an example, other values greater than zero can also be taken, which is specific according to the actual situation), x can be -10% (only an example, other values less than zero can also be taken, which is specific according to the actual situation), and y can be 10% (only an example, other values greater than zero can also be taken, which is specific according to the actual situation). It should be noted that Tn-Ts=m is a critical case, which can be attributed to Tn-Ts>m becoming Tn-Ts≥m, or Tn-Ts<n becoming Tn-Ts≤m, which is not specifically limited here; Tn-Ts=n, RHn-RHs=x and RHn-RHs=y are the same.

[0055] Exemplarily, Figure 4 The temperature and humidity double control mode corresponding to each zone is shown in Table 2:

[0056]

[0057]

[0058] Table 2

[0059] Wherein, the reason why the A zone and the F zone are the same temperature and humidity double control mode is that, referring to the temperature and humidity double control mode corresponding to the B zone, the temperature and humidity double control mode corresponding to the A zone is the same as the temperature and humidity double control mode corresponding to the F zone. Figure 4As can be seen from Table 1, the A area and the F area both belong to the case that the indoor temperature is low, and the difference between the two areas is that the indoor humidity of the A area is appropriate while the indoor humidity of the F area is low. When the indoor environment corresponding to the two areas is close to the indoor environment corresponding to the E area through the control of the air conditioner, because most air conditioners do not have a humidifying function, the indoor temperature needs to be changed in the A area and the F area without changing the indoor humidity, so the control mode of the air conditioner corresponding to the A area and the F area should be the same, that is, corresponding to the same temperature and humidity double control mode. Similarly, the E area and the G area should also correspond to the same temperature and humidity double control mode of the air conditioner, and the C area and the H area should also correspond to the same temperature and humidity double control mode of the air conditioner. The reason why the temperature and humidity double control mode of the air conditioner corresponding to the I area and the D area is the same is that the I area and the D area both belong to the case that the indoor humidity is high, and the difference between the two is that the temperature of the I area is appropriate and the temperature of the D area is high. At present, the same control mode is used for the air conditioner when the indoor humidity needs to be reduced and the indoor temperature needs to be reduced, that is, the air conditioner is cooled or dehumidified, so because the I area mainly needs dehumidification and the D area needs to be cooled and dehumidified, the control mode used by the two is the same, that is, the corresponding temperature and humidity double control mode should be the same.

[0060] Of course, the above-mentioned areas corresponding to the same temperature and humidity double control mode are only one possible example, and in actual use, other corresponding relationships can also be used according to the difference of the air conditioner itself, which is not limited here.

[0061] Based on the above description, the plurality of temperature and humidity double control modes can include a first temperature and humidity double control mode, a second temperature and humidity double control mode, a third temperature and humidity double control mode, a fourth temperature and humidity double control mode, and a fifth temperature and humidity double control mode. Further optionally, referring to FIG. 3, the step 304 specifically includes 3041-3045. Figure 5

[0062] 3041, when it is determined that the first temperature difference and the first humidity difference satisfy a first preset condition, determining the first temperature and humidity double control mode as the target temperature and humidity double control mode.

[0063] The first preset condition includes that the first temperature difference is less than a first temperature threshold value and the first humidity difference is less than a second humidity threshold value. The first preset condition is the union of the difference value range corresponding to the A area, the difference value range corresponding to the F area and RHn-RHs=x shown in Table 1 and Table 2; therefore, when it is determined that the first temperature difference and the first humidity difference satisfy the first preset condition, it is determined that the current indoor environment corresponds to the union of the A area and the F area. Figure 4 Figure 4

[0064] 3042, when it is determined that the first temperature difference and the first humidity difference satisfy a second preset condition, determining the second temperature and humidity double control mode as the target temperature and humidity double control mode.

[0065] ​​​The fifth preset condition comprises: the second preset condition comprises: the first temperature difference is less than the first temperature threshold, and the first humidity difference is greater than the second humidity threshold. The second preset condition is a difference range corresponding to the B area shown in Table 1 and Figure 4 Table 2; therefore, when it is determined that the first temperature difference and the first humidity difference satisfy the second preset condition, it is determined that the current indoor environment corresponds to the B area in Table 1 and Figure 4 Table 2.

[0066] 3043, when it is determined that the first temperature difference and the first humidity difference satisfy the third preset condition, the third temperature and humidity dual-control mode is determined as the target temperature and humidity dual-control mode.

[0067] The third preset condition comprises: the first temperature difference is greater than the second temperature threshold, and the first humidity difference is less than the second humidity threshold; and the second temperature threshold is greater than the first temperature threshold. The first preset condition is a union of a difference range corresponding to the C area, a difference range corresponding to the H area, and RHn-RHs=x shown in Table 1 and Figure 4 Table 2; therefore, when it is determined that the first temperature difference and the first humidity difference satisfy the third preset condition, it is determined that the current indoor environment corresponds to a union of the C area and the H area in Table 1 and Figure 4 Table 2.

[0068] 3044, when it is determined that the first temperature difference and the first humidity difference satisfy the fourth preset condition, the fourth temperature and humidity dual-control mode is determined as the target temperature and humidity dual-control mode.

[0069] The fourth preset condition comprises: the first temperature difference is greater than the first temperature threshold, and the first humidity difference is greater than the second humidity threshold. The first preset condition is a union of a difference range corresponding to the D area, a difference range corresponding to the I area, and Tn-Ts=n shown in Table 1 and Figure 4 Table 2; therefore, when it is determined that the first temperature difference and the first humidity difference satisfy the fourth preset condition, it is determined that the current indoor environment corresponds to a union of the D area and the I area in Table 1 and Figure 4 Table 2.

[0070] 3045, when it is determined that the first temperature difference and the first humidity difference satisfy the fifth preset condition, the fifth temperature and humidity dual-control mode is determined as the target temperature and humidity dual-control mode.

[0071] The fifth preset condition comprises: the first temperature difference is less than the second temperature threshold and greater than the first temperature threshold, and the first humidity difference is less than the second humidity threshold. The first preset condition is a union of a difference range corresponding to the E area, a difference range corresponding to the G area, and RHn-RHs=x shown in Table 1 and Figure 4 Table 2; therefore, when it is determined that the first temperature difference and the first humidity difference satisfy the fifth preset condition, it is determined that the current indoor environment corresponds to a union of the E area and the G area in Table 1 and Figure 4 Table 2.

[0072] 305、control the air conditioner to execute the target temperature and humidity dual-control mode.

[0073] In an implementable manner, with reference to Figure 6 as shown, when the target temperature and humidity dual-control mode is the first temperature and humidity dual-control mode, the step 305 specifically includes: S11-S14.

[0074] S11, control the air conditioner to run in the heating mode.

[0075] When it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity satisfy the first preset condition, it indicates that the indoor humidity of the current indoor environment is not too high (less than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is too low (less than the sum of the first temperature threshold and the indoor set temperature). Since most air conditioners cannot increase the indoor humidity, the air conditioner should adopt the heating mode to increase the indoor temperature in this case, and on the basis of not being able to ensure the increase of the indoor humidity, the demand of the user for the indoor temperature is ensured.

[0076] S12, obtain the third indoor temperature corresponding to the air conditioner running in the heating mode, and calculate the third temperature difference between the third indoor temperature and the indoor set temperature.

[0077] It should be noted that when the step 302 specifically obtains the current indoor temperature of the air conditioner as the first indoor temperature and the indoor humidity as the first indoor humidity, the third indoor temperature in the step S12 can be the current indoor temperature obtained in real time.

[0078] S13, determine whether the third temperature difference is greater than the first temperature threshold and less than the second temperature threshold.

[0079] When it is determined that the third temperature difference is greater than the first temperature threshold and less than the second temperature threshold, S14 is executed; when it is determined that the third temperature difference is less than the first temperature threshold or greater than the second temperature threshold, S11 is executed. It should be noted that the third temperature difference equal to the first temperature threshold is a critical case, which can be attributed to the case that the third temperature difference is less than the first temperature threshold or the case that the third temperature difference is greater than the first temperature threshold, which is not specifically limited here; the third temperature difference equal to the second temperature threshold is the same.

[0080] S14, control the outdoor unit of the air conditioner to stop running, and control the indoor unit of the air conditioner to run in the air supply mode.

[0081] When the indoor temperature has met the requirement, because the humidity cannot be changed, it can be considered that the indoor environment has approached the indoor environment required by the user at this time, so the air conditioner does not heat or cool at this time, and only functions as a fan, that is, the step S14.

[0082] The technical scheme provided in the application, when the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity meet the first preset condition, it indicates that the indoor humidity in the current indoor environment is not too high (less than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is too low (less than the sum of the first temperature threshold and the indoor set temperature), at this time, the air conditioner is controlled to heat until the indoor temperature is between the first temperature threshold and the second temperature threshold, so that the indoor environment reaches or approaches the Figure 4 indoor environment corresponding to the E area in the middle. In the case where the humidity cannot be increased, the demand of the user for the indoor temperature is ensured.

[0083] It should be noted that when the air conditioner itself is provided with a humidifying device, in order to further ensure that the indoor humidity meets the demand of the user for the humidity, after the step S14, the method can further include: acquiring the current indoor humidity, when it is determined that the difference between the current indoor humidity and the indoor set humidity is not between the first humidity threshold and the second humidity threshold, the humidifying device is controlled to work until the difference between the current indoor humidity and the indoor set humidity is between the first humidity threshold and the second humidity threshold.

[0084] In an implementable manner, referring to FIG. 3, Figure 7 when the target temperature and humidity double-control mode is the second temperature and humidity double-control mode, the step 305 specifically includes steps S21-S28.

[0085] S21, control the air conditioner to run in a heating mode.

[0086] When it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity meet the second preset condition, it indicates that the indoor humidity in the current indoor environment is too high (greater than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is too low (less than the sum of the first temperature threshold and the indoor set temperature), so for this case, the air conditioner can first run in a heating mode to increase the indoor temperature and then run in a cooling or dehumidifying mode to reduce the indoor humidity.

[0087] S22, acquire a fourth indoor temperature and a third indoor humidity corresponding to the air conditioner running in the heating mode, and calculate a fourth temperature difference between the fourth indoor temperature and the indoor set temperature.

[0088] It should be noted that when the step 302 specifically acquires the current indoor temperature of the air conditioner as the first indoor temperature and the indoor humidity as the first indoor humidity, the fourth indoor temperature in the step S22 can be the current indoor temperature acquired in real time, and the third indoor humidity can be the current indoor humidity acquired in real time.

[0089] S23, determine whether the fourth temperature difference is greater than a third temperature threshold.

[0090] When it is determined that the fourth temperature difference is greater than the third temperature threshold, S24 is executed; when it is determined that the fourth temperature difference is not greater than the third temperature threshold, S21 is executed. The third temperature threshold is greater than the first temperature threshold and less than the second temperature threshold; for example, the third temperature threshold can be 0℃ (only an example, other values can also be used, as long as it is between the first temperature threshold and the second temperature threshold). The significance of setting the third temperature threshold is that the indoor environment corresponding to the second temperature and humidity control mode is Figure 4 The indoor environment corresponding to the middle B has a low indoor temperature and a high indoor humidity, so after the air conditioner runs in the heating mode to raise the indoor temperature, it needs to run in the cooling mode or dehumidification mode to reduce the indoor humidity. Therefore, in order to avoid the influence of the subsequent cooling mode or dehumidification mode, the heating mode needs to slightly raise the indoor temperature within the fourth temperature difference tolerable range (between the first temperature threshold and the second temperature threshold) to prevent the subsequent cooling mode or dehumidification mode from reducing the indoor temperature to outside the tolerable range. Therefore, any value between the first temperature threshold and the second temperature threshold is taken as the third temperature threshold.

[0091] It should be noted that the fourth temperature difference equal to the third temperature threshold is a critical case, which can be attributed to the case where the fourth temperature difference is less than the third temperature threshold, or the case where the fourth temperature difference is greater than the third temperature threshold. Here, no specific limitation is made. In the judgment process of S23, the fourth temperature difference equal to the third temperature threshold is attributed to the case where the fourth temperature difference is less than the third temperature threshold.

[0092] S24, calculating a third humidity difference of the third indoor humidity and the indoor set humidity.

[0093] S25, judging whether the third humidity difference is greater than a first humidity threshold.

[0094] When it is determined that the third humidity difference is greater than the first humidity threshold, S26 is executed; when it is determined that the third humidity difference is not greater than the first humidity threshold, S28 is executed. It should be noted that the third humidity difference equal to the first humidity threshold is a critical case, which can be attributed to the case where the third humidity difference is less than the first humidity threshold, or the case where the third humidity difference is greater than the first humidity threshold. Here, no specific limitation is made. In the judgment process of S25, the third humidity difference equal to the second humidity threshold is attributed to the case where the third humidity difference is less than the first humidity threshold.

[0095] The significance of S25 is that when the air conditioner is heating, the increase of the indoor temperature will also cause the decrease of the indoor humidity. In normal cases, the decrease is not large, but when the second humidity threshold is set to be small or the heating capacity of the air conditioner is high, the heating of the air conditioner will cause the indoor humidity to decrease to the user's demand range Figure 4Since the humidity level is outside the range corresponding to zone E in the table, the indoor humidity needs to be relatively low before the air conditioner can be switched to cooling or dehumidification mode. If the humidity drops too much, the cooling or dehumidification mode will no longer be needed. Therefore, when heating, it is necessary to constantly check whether the third humidity difference exceeds the minimum value of the user's required range (the humidity difference range corresponding to zone E in Table 1).

[0096] S26. Determine whether the third humidity difference is greater than the second humidity threshold.

[0097] When the third humidity difference is greater than the second humidity threshold, execute S27; when the third humidity difference is not greater than the second humidity threshold, execute S28. It should be noted that the third humidity difference being equal to the second humidity threshold is a critical case, which can be categorized as either the third humidity difference being less than the second humidity threshold or the third humidity difference being greater than the second humidity threshold; no specific restriction is made here. In the judgment process of S25, the case where the third humidity difference is equal to the second humidity threshold is categorized as the case where the third humidity difference is less than the second humidity threshold.

[0098] S27. Control the air conditioner to operate in either cooling or dehumidification mode.

[0099] S25 is executed after S27. Executing S25 after S27 is to prevent the indoor humidity from dropping below the minimum value of the user's required range (the humidity difference range corresponding to zone E in Table 1) when the cooling or dehumidification mode is activated.

[0100] S28. Control the outdoor unit of the air conditioner to stop running and control the indoor unit of the air conditioner to run in air supply mode.

[0101] When both indoor temperature and humidity meet the requirements, or when the indoor temperature meets the requirements but the indoor humidity does not meet the requirements but cannot be changed, the indoor environment can be considered to be close to the indoor environment required by the user. Therefore, at this time, the air conditioner can be set to neither heat nor cool, but only act as a fan, i.e., step S28.

[0102] It should be noted that when the air conditioner itself is equipped with a humidification device, in order to further ensure that the indoor humidity meets the user's humidity requirements, step S28 may also include: obtaining the current indoor humidity, and when it is determined that the difference between the current indoor humidity and the indoor set humidity is not between the first humidity threshold and the second humidity threshold, controlling the humidification device to work until the difference between the current indoor humidity and the indoor set humidity is between the first humidity threshold and the second humidity threshold, and then stopping.

[0103] In another possible implementation, refer to Figure 8 As shown, when the target temperature and humidity dual control mode is the second temperature and humidity dual control mode, step 305 specifically includes: S21A-S28A:

[0104] S21A, controlling the air conditioner to run in a cooling mode or a dehumidifying mode.

[0105] When it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity satisfy the second preset condition, it indicates that the indoor humidity of the current indoor environment is high (greater than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is low (less than the sum of the first temperature threshold and the indoor set temperature), so the air conditioner can run in the cooling mode or the dehumidifying mode to reduce the indoor humidity first, and then run in the heating mode to increase the indoor temperature.

[0106] S22A, acquiring a fourth indoor temperature and a third indoor humidity corresponding to the air conditioner running in the cooling mode or the dehumidifying mode, and calculating a third humidity difference between the third indoor humidity and the indoor set humidity.

[0107] It should be noted that when the current indoor temperature of the air conditioner is acquired as the first indoor temperature and the indoor humidity is acquired as the first indoor humidity in the step 302, the fourth indoor temperature in the step S22 can be the current indoor temperature acquired in real time, and the third indoor humidity can be the current indoor humidity acquired in real time.

[0108] S23A, determining whether the third humidity difference is greater than a third humidity threshold.

[0109] When it is determined that the third humidity difference is greater than the third humidity threshold, S24A is executed; when it is determined that the third humidity difference is not greater than the third humidity threshold, S21A is executed. The third humidity threshold is greater than the first humidity threshold and less than the second humidity threshold. It should be noted that the case that the third humidity difference is equal to the third humidity threshold is a critical case, which can be attributed to the case that the third humidity difference is less than the third humidity threshold, or can be attributed to the case that the third humidity difference is greater than the third humidity threshold, which is not limited specifically herein. In the determination process of S23A, the case that the third humidity difference is equal to the second humidity threshold is attributed to the case that the third humidity difference is less than the first humidity threshold. Exemplarily, the third humidity threshold can be 15% (only an example, and other values can also be used as long as the third humidity threshold is between the first humidity threshold and the second humidity threshold). The significance of setting the third humidity threshold is that the indoor environment corresponding to the second temperature and humidity dual-control mode is Figure 4The indoor environment corresponding to the middle B has a low indoor humidity and a high indoor humidity, so after the air conditioner runs in the cooling mode or the dehumidification mode to reduce the indoor humidity, the heating mode is needed to raise the indoor temperature. The temperature rise will also cause the indoor humidity to decrease, so in order to avoid the dehumidification effect caused by the subsequent heating mode, the cooling mode or the dehumidification mode needs to slightly increase the indoor humidity within the fourth humidity difference tolerable range (between the first humidity threshold and the second humidity threshold) to prevent the subsequent heating mode from reducing the indoor humidity to make the fourth humidity difference outside the tolerable range, so any value of the first humidity threshold and the second humidity threshold is taken as the third humidity threshold.

[0110] S24A, calculate a fourth temperature difference of the fourth indoor temperature and the indoor set temperature.

[0111] S25A, determine whether the fourth temperature difference is greater than a first temperature threshold.

[0112] When it is determined that the fourth temperature difference is greater than the first temperature threshold, S26A is executed; when it is determined that the fourth temperature difference is not greater than the first temperature threshold, S28A is executed.

[0113] It should be noted that the fourth temperature difference equal to the first temperature threshold is a critical case, which can be attributed to the case where the fourth temperature difference is less than the first temperature threshold, or the case where the fourth temperature difference is greater than the first temperature threshold, which is not specifically limited here. In the judgment process of S25A, the fourth temperature difference equal to the first temperature threshold is attributed to the case where the fourth temperature difference is less than the first temperature threshold.

[0114] S26A, determine whether the fourth temperature difference is greater than a second temperature threshold.

[0115] When the fourth temperature difference is greater than the second temperature threshold, S27A is executed; when the fourth temperature difference is not greater than the second temperature threshold, S28A is executed. It should be noted that the fourth temperature difference equal to the second temperature threshold is a critical case, which can be attributed to the case where the fourth temperature difference is less than the second temperature threshold, or the case where the fourth temperature difference is greater than the second temperature threshold, which is not specifically limited here. In the judgment process of S25, the fourth temperature difference equal to the second temperature threshold is attributed to the case where the fourth temperature difference is less than the second temperature threshold.

[0116] S27A, control the air conditioner to run in the heating mode.

[0117] S25A is executed after S27A. S25A is executed after S27A in order to avoid the heating mode from raising the indoor temperature to above the maximum value of the user demand range (the temperature difference range corresponding to region E in Table 1).

[0118] S28A, control the outdoor unit of the air conditioner to stop running, and control the indoor unit of the air conditioner to run in the air supply mode.

[0119] When the indoor temperature and the indoor humidity have both met the requirements, or the indoor temperature meets the requirements and the indoor humidity does not meet the requirements but cannot be changed, it can be considered that the indoor environment has approached the indoor environment required by the user at this time, so the air conditioner is not heated or cooled at this time, and only functions as a fan, that is, the step S28.

[0120] It should be noted that when the air conditioner itself is provided with a humidifying device, in order to further ensure that the indoor humidity meets the user's demand for humidity, the step S28 can further include: obtaining the current indoor humidity, and when it is determined that the difference between the current indoor humidity and the indoor set humidity is not between the first humidity threshold and the second humidity threshold, controlling the humidifying device to work until the difference between the current indoor humidity and the indoor set humidity is between the first humidity threshold and the second humidity threshold.

[0121] In the technical scheme provided in the present application, when it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity meet the second preset condition, that is, when the current indoor humidity is too high (greater than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is too low (less than the sum of the first temperature threshold and the indoor set temperature), on the one hand, the air conditioner can be controlled to first heat until the indoor temperature is between the first temperature threshold and the second temperature threshold, and then it is determined whether to cool or dehumidify according to the indoor humidity, and if it is determined that the indoor humidity is still too high, the air conditioner is controlled to run in the cooling mode or the dehumidifying mode until the indoor humidity is between the first humidity threshold and the second humidity threshold; on the other hand, the air conditioner can be controlled to first cool or dehumidify until the indoor humidity is between the first humidity threshold and the second humidity threshold, and then it is determined whether to heat according to the indoor temperature, and if it is determined that the indoor temperature is still too low, the air conditioner is controlled to run in the heating mode until the indoor temperature is between the first temperature threshold and the second temperature threshold. Thus, the indoor environment approaches Figure 4 the indoor environment corresponding to the E area in the middle. Therefore, the high technical scheme provided in the embodiments of the present application can ensure the user's demand for the indoor environment in terms of temperature and humidity when controlling the air conditioner.

[0122] In an implementable manner, referring to FIG. 5, when the target temperature and humidity double-control mode is the third temperature and humidity double-control mode, the step 305 specifically includes the following steps S31-S310. Figure 9

[0123] S31, control the air conditioner to run in the cooling mode or the dehumidifying mode.

[0124] ​When it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity satisfy the third preset condition, it indicates that the indoor humidity of the current indoor environment is not too high (less than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is too high (greater than the sum of the second temperature threshold and the indoor set temperature), so the air conditioner should first consider running in the cooling mode or the dehumidification mode to reduce the indoor temperature.

[0125] S32, acquire the fifth indoor temperature, the fourth indoor humidity and the first saturation temperature of the indoor heat exchanger when the air conditioner runs in the cooling mode or the dehumidification mode, and calculate the first dew point temperature of the indoor environment corresponding to the air conditioner according to the fifth indoor temperature and the fourth indoor humidity.

[0126] It should be noted that when the step 302 specifically acquires the current indoor temperature of the air conditioner as the first indoor temperature and the indoor humidity as the first indoor humidity, the fifth indoor temperature in the step S12 can be the current indoor temperature acquired in real time, and the fourth indoor humidity can be the current indoor humidity acquired in real time.

[0127] When calculating the first dew point temperature of the indoor environment corresponding to the air conditioner according to the fifth indoor temperature and the fourth indoor humidity, the following formula needs to be used:

[0128] Td = RHn * 100 * (a + b * Tn) + c * Tn - d (1)

[0129] Wherein, Tn is the indoor temperature (according to which indoor temperature to calculate, the corresponding data is substituted), Td is the dew point temperature (according to which dew point temperature to calculate, Td is the dew point temperature), RHn is the indoor humidity (according to which indoor humidity to calculate, the corresponding data is substituted), a = 0.199, b = 0.0018, c = 0.85, d = 19.3, a, b, c and d are all calculation parameters. It should be noted that the above formula (1) is an empirical formula obtained according to actual data, which is only an example, and the calculation parameters in the formula may change in practice, which is not limited here.

[0130] S33, calculate the first condensation temperature difference between the first dew point temperature and the first saturation temperature, and the fifth temperature difference between the fifth indoor temperature and the indoor set temperature.

[0131] S34, judge whether the first condensation temperature difference is greater than the fourth temperature threshold.

[0132] When it is determined that the first condensation temperature difference is greater than the fourth temperature threshold, S35 is executed; when it is determined that the first condensation temperature difference is not greater than the fourth temperature threshold, S36 is executed. Exemplarily, the fourth temperature threshold can be 10℃ (only an example, which can be other values greater than zero).

[0133] The purpose of the step S34 is that the greater the difference between the temperature of the indoor heat exchanger and the indoor dew point temperature, the more likely it is to cause the water vapor in the indoor air to condense, thereby reducing the indoor humidity, and the third temperature and humidity dual-control mode is for an indoor environment in which the indoor temperature is too high (greater than the sum of the second temperature threshold and the indoor set temperature) and the indoor humidity is not too high (less than the sum of the second humidity threshold and the indoor set humidity), so as to reduce the condensation of water vapor in the indoor air as much as possible when reducing the indoor temperature, it is necessary to avoid the temperature of the indoor heat exchanger being much lower than the dew point temperature of the indoor air (greater than the fourth temperature threshold), so it is necessary to make the judgment of S34, if the first condensation temperature difference is greater than the fourth temperature threshold, then the subsequent corresponding control (step S310) is needed to make the first condensation temperature difference less than the fourth temperature threshold, so as to reduce the speed of condensation of water vapor in the indoor air.

[0134] It should be noted that the case where the first condensation temperature difference is equal to the fourth temperature threshold is a critical case, which can be attributed to the case where the first condensation temperature difference is less than the fourth temperature threshold, or the case where the first condensation temperature difference is greater than the fourth temperature threshold, which is not limited specifically here. In the judgment process of S34, the case where the first condensation temperature difference is equal to the fourth temperature threshold is attributed to the case where the first condensation temperature difference is less than the fourth temperature threshold.

[0135] S35, judge whether the fifth temperature difference is greater than the first temperature threshold.

[0136] When it is determined that the fifth temperature difference is greater than the first temperature threshold, S37 is executed; when it is determined that the fifth temperature difference is not greater than the first temperature threshold, S38 is executed.

[0137] The purpose of the step S35 is that after the air conditioner runs in the cooling mode or the dehumidification mode, the main purpose is to reduce the temperature, so after judging the size relationship between the first condensation temperature difference and the fourth temperature threshold, it is also necessary to judge the size relationship between the fifth temperature difference and the first temperature threshold, when the fifth temperature difference is less than the first temperature threshold, it indicates that the current indoor temperature has been reduced too low, and the cooling mode or the dehumidification mode cannot be continued to run; when the fifth temperature difference is greater than the first temperature threshold, it indicates that the current indoor temperature has not been reduced to a too low degree, and it is necessary to determine whether the cooling mode or the dehumidification mode needs to be stopped running subsequently.

[0138] For example, when the fourth temperature threshold is set to be smaller or the first temperature threshold is larger or the cooling effect of the air conditioner is higher, it is possible to appear the case where the first condensation temperature is greater than the fourth temperature threshold and the fifth temperature difference is less than the first temperature threshold; under normal circumstances, this case generally does not occur.

[0139] S36, judge whether the fifth temperature difference is greater than the first temperature threshold.

[0140] When it is determined that the fifth temperature difference is greater than the first temperature threshold, S39 is performed; when it is determined that the fifth temperature difference is not greater than the first temperature difference, S38 is performed.

[0141] S36 has the same meaning as S35, which will not be repeated here.

[0142] It should be noted that the case where the fifth temperature difference is equal to the first temperature threshold is a critical case, which can be attributed to the case where the fifth temperature difference is less than the first temperature threshold, or the case where the fifth temperature difference is greater than the first temperature threshold, which is not specifically limited here. In the judgment process of S35 and S36, the case where the fifth temperature difference is equal to the first temperature threshold is attributed to the case where the fifth temperature difference is less than the first temperature threshold.

[0143] S37, determine whether the fifth temperature difference is greater than the second temperature threshold.

[0144] When it is determined that the fifth temperature difference is greater than the second temperature threshold, S310 is performed; when it is determined that the fifth temperature difference is not greater than the second temperature threshold, S38 is performed.

[0145] S37 is to determine whether the current indoor temperature is too high when it is determined that the first condensation temperature difference is greater than the fourth temperature threshold and the fifth temperature difference is greater than the first temperature threshold, i.e., when the condensation speed of water vapor in the current indoor air is fast and the indoor temperature is not too low. If the current indoor temperature is too high (the fifth temperature difference is greater than the second temperature threshold), the air conditioner is operated in the cooling mode or the dehumidification mode, and the condensation speed of water vapor in the current indoor air is slowed down by corresponding control of the air conditioner (S310). If the current indoor temperature is neither too high nor too low (the fifth temperature difference is greater than the first temperature threshold and less than the second temperature threshold), it indicates that the third temperature and humidity dual control has achieved the purpose of cooling, and the humidity does not need to be reduced. Therefore, the air conditioner needs to be stopped from operating in the cooling mode or the dehumidification mode to prevent the indoor temperature from being too low (the fifth temperature difference is less than the first temperature threshold). Therefore, S37 is needed to determine whether to stop operating in the cooling mode or the dehumidification mode when the condensation speed of water vapor in the indoor air is fast, or to slow down the condensation speed of water vapor in the current indoor air by corresponding operation of the air conditioner.

[0146] S38, control the outdoor unit of the air conditioner to stop operating, and control the indoor unit of the air conditioner to operate in the air supply mode.

[0147] When the current indoor temperature is too low (the fifth temperature difference is less than the first temperature threshold), or the current indoor temperature is appropriate (the fifth temperature difference is greater than the first temperature threshold and less than the second temperature threshold), it indicates that the air conditioner does not need to operate in the cooling mode or the dehumidification mode, and only needs to act as an indoor fan. Therefore, S38 is performed in these two cases.

[0148] S39, determining whether the fifth temperature difference is greater than the second temperature threshold.

[0149] When it is determined that the fifth temperature difference is greater than the second temperature threshold, S31 is executed; when it is determined that the fifth temperature difference is not greater than the second temperature threshold, S38 is executed.

[0150] The purpose of the S39 step is that when it is determined that the first condensation temperature difference is less than the fourth temperature threshold and the fifth temperature difference is greater than the first temperature threshold, it indicates that the condensation speed of the water vapor in the current indoor air is slow and the indoor temperature is not too high, and it is necessary to determine whether the current indoor temperature is too high. If the current indoor temperature is too high (the fifth temperature difference is greater than the second temperature threshold), the air conditioner needs to continue to run in the cooling mode or the dehumidification mode (i.e., S31 is executed). If the current indoor temperature is neither too high nor too low (the fifth temperature difference is greater than the first temperature threshold and less than the second temperature threshold), it indicates that the third temperature and humidity dual control cooling purpose has been achieved, and the humidity does not need to be reduced, so the air conditioner needs to stop running in the cooling mode or the dehumidification mode at this time to prevent the indoor temperature from being too low (the fifth temperature difference is less than the first temperature threshold). Therefore, the S39 step is needed to determine whether to stop running in the cooling mode or the dehumidification mode when the condensation speed of the water vapor in the indoor air is slow.

[0151] It should be noted that the fifth temperature difference equal to the second temperature threshold is a critical case, which can be attributed to the case where the fifth temperature difference is less than the second temperature threshold, or the case where the fifth temperature difference is greater than the second temperature threshold, which is not specifically limited here. In the judgment process of S37 and S39, the fifth temperature difference equal to the second temperature threshold is attributed to the case where the fifth temperature difference is less than the first temperature threshold.

[0152] S310, reducing the operating frequency of the compressor of the air conditioner.

[0153] After S310, S31 is executed.

[0154] Specifically, the amount of refrigerant input into the indoor heat exchanger can directly affect the cooling, heating, and dehumidification effects, and the amount of input refrigerant depends on the operating frequency of the compressor. When the operating frequency of the compressor is high, the amount of refrigerant discharged into the air conditioner refrigerant circulation system is also large, so the amount of refrigerant flowing through the indoor heat exchanger also increases, thereby accelerating the cooling, heating, and dehumidification efficiency. When the operating frequency of the compressor is low, the amount of refrigerant discharged into the air conditioner refrigerant circulation system is also small, so the amount of refrigerant flowing through the indoor heat exchanger also decreases, thereby delaying the cooling, heating, and dehumidification process. Therefore, in order to reduce the speed of reducing indoor humidity (the condensation speed of water vapor in indoor air) when the air conditioner is running in the cooling mode or the dehumidification mode, it is necessary to reduce the operating frequency of the compressor.

[0155] In order to prevent the stable operation of the compressor, the frequency cannot be reduced too much and cannot be reduced below the preset minimum operating frequency each time, so S310 is specifically: when the current operating frequency of the compressor is not greater than the sum of the minimum operating frequency and the preset step value, the operating frequency of the compressor is not changed; when the current operating frequency of the compressor is greater than the sum of the minimum operating frequency and the preset step value, the operating frequency of the compressor is reduced by the preset step value. Exemplarily, the preset step value can be 10 Hz (only as an example, which can be other values greater than zero).

[0156] Further optionally, because the greater the speed of the indoor fan, the faster the indoor air circulates in the indoor unit, and the faster the circulation, the shorter the time for the indoor air to contact the indoor heat exchanger, and the indoor air vapor also does not have sufficient time to condense on the indoor heat exchanger, which is equivalent to reducing the speed of condensation of the indoor air vapor (the speed of reducing the indoor humidity); at the same time, the faster the wind speed, the water droplets condensed on the indoor heat exchanger can also be blown out of the indoor unit to evaporate in the room, which further reduces the speed of condensation of the indoor air vapor (the speed of reducing the indoor humidity). Therefore, S310 further includes: increasing the speed of the indoor fan of the air conditioner. Specifically, increasing the speed of the indoor fan of the air conditioner can be increasing the speed of the indoor fan by a target value or increasing the speed of the indoor fan by one gear. For example, increasing the speed of the indoor fan by 200 r / min (target value, only as an example). For another example, if the current speed of the indoor fan corresponds to a low speed gear, the speed of the indoor fan is increased to a medium speed gear (only as an example, which can also be a high speed gear, etc.).

[0157] It should be noted that when the air conditioner itself is provided with a humidifying device, in order to further ensure that the indoor humidity meets the user's demand for humidity, S38 can further include: obtaining the current indoor humidity, and when it is determined that the difference between the current indoor humidity and the indoor set humidity is not between the first humidity threshold and the second humidity threshold, controlling the humidifying device to work until the difference between the current indoor humidity and the indoor set humidity is between the first humidity threshold and the second humidity threshold.

[0158] The technical scheme provided by the embodiment of the application is that when it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity satisfy the third preset condition, that is, when the current indoor temperature is too high (greater than the sum of the second temperature threshold and the indoor set temperature) and the indoor humidity is not too high (not greater than the sum of the second humidity threshold and the indoor set humidity), the temperature difference between the indoor heat exchanger and the dew point temperature of the indoor air is small through the control of the compressor frequency, so as to prevent the water vapor in the indoor air from condensing too fast, and the indoor humidity is prevented from being reduced too much when the indoor temperature reaches the user demand range (greater than the sum of the first temperature threshold and the indoor set temperature and less than the sum of the second temperature threshold and the indoor set temperature). Therefore, the technical scheme provided by the embodiment of the application can meet the user demand from the aspects of temperature and humidity when the air conditioner is controlled, and the user experience is improved.

[0159] In an implementable manner, referring to FIG. 5, when the target temperature and humidity double-control mode is the fourth temperature and humidity double-control mode, the step 305 specifically includes the following steps S41-S410. Figure 10

[0160] S41, control the air conditioner to run in the cooling mode or the dehumidification mode.

[0161] When it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity satisfy the fourth preset condition, that is, when the current indoor humidity is too high (greater than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is not too low (greater than the sum of the first temperature threshold and the indoor set temperature), therefore, the air conditioner should first adopt the cooling mode or the dehumidification mode to reduce the indoor humidity, so as to ensure the user demand for the indoor humidity.

[0162] S42, acquire the sixth indoor temperature, the fifth indoor humidity and the second saturation temperature of the indoor heat exchanger corresponding to the cooling mode or the dehumidification mode of the air conditioner, and calculate the fourth humidity difference between the fifth indoor humidity and the indoor set humidity and the sixth temperature difference between the sixth indoor temperature and the indoor set temperature.

[0163] It should be noted that when the step 302 specifically acquires the current indoor temperature of the air conditioner as the first indoor temperature and the indoor humidity as the first indoor humidity, the sixth indoor temperature in the step S42 can be the current indoor temperature acquired in real time, and the fifth indoor humidity can be the current indoor humidity acquired in real time.

[0164] S43, determine whether the fourth humidity difference is greater than the first humidity threshold and less than the second humidity threshold.

[0165] ​When it is determined that the fourth humidity difference is greater than the first humidity threshold and less than the second humidity threshold, S44 is performed; when it is determined that the fourth humidity difference is not greater than the first humidity threshold or not less than the second humidity threshold, S45 is performed. Wherein, because the indoor humidity in the indoor environment corresponding to the fourth temperature and humidity dual-control mode is greater than the sum of the second humidity threshold and the indoor set humidity, and the air conditioner is currently running in the cooling mode or the dehumidification mode, the indoor humidity will gradually decrease, and because there is a certain interval between the first humidity threshold and the second humidity threshold, once the fourth humidity difference is not between the first humidity threshold and the second humidity threshold, other steps will be performed, so in the case that the fourth humidity difference is not greater than the first humidity threshold or not less than the second humidity threshold, there is basically only the case that the fourth humidity difference is not less than the second humidity threshold. Of course, if the case that the fourth humidity difference is not greater than the first humidity threshold occurs, S43 is directly followed by S47.

[0166] Because the indoor humidity in the indoor environment corresponding to the fourth temperature and humidity dual-control mode is greater than the sum of the second humidity threshold and the indoor set humidity, the primary purpose of the fourth temperature and humidity dual-control mode is to reduce the humidity so that the indoor humidity is between the sum of the first humidity threshold and the indoor set humidity and the sum of the second humidity threshold and the indoor set humidity, i.e. the fourth humidity difference is between the first humidity threshold and the second humidity threshold, so the judgment of S43 needs to be performed.

[0167] It should be noted that the case that the fourth humidity difference is equal to the first humidity threshold is a critical case, which can be attributed to the case that the fourth humidity difference is greater than the first humidity threshold or the case that the fourth humidity difference is less than the first humidity threshold, which is not specifically limited here; the case that the fourth humidity difference is equal to the second humidity threshold is the same. In the judgment process of S43, the case that the fourth humidity difference is equal to the first humidity threshold is attributed to the case that the fourth humidity difference is less than the first humidity threshold, and the case that the fourth humidity difference is equal to the second humidity threshold is attributed to the case that the fourth humidity difference is greater than the second humidity threshold.

[0168] S44, whether the sixth temperature difference is greater than the first temperature threshold.

[0169] When it is determined that the sixth temperature difference is greater than the first temperature threshold, S46 is performed; when it is determined that the sixth temperature difference is not greater than the first temperature threshold, S47 is performed.

[0170] When the fourth humidity difference is determined to be between the first humidity threshold value and the second humidity threshold value, i.e. the indoor humidity is in the user demand range (between the sum of the first humidity threshold value and the indoor set humidity and the sum of the second humidity threshold value and the indoor set humidity), since the air conditioner is currently still in the cooling mode or the dehumidifying mode, it is also necessary to ensure that the indoor temperature will not be lower than the minimum value in the user demand range (between the sum of the first temperature threshold value and the indoor set temperature and the sum of the second temperature threshold value and the indoor set temperature); once the indoor temperature is lower than the minimum value in the user demand range, the air conditioner needs to be controlled to stop running in the cooling mode or the dehumidifying mode in time. Therefore, the step S44 needs to be performed.

[0171] It should be noted that the sixth temperature difference being equal to the first temperature threshold value is a critical case, which can be attributed to the case that the sixth temperature difference is greater than the first temperature threshold value or the case that the sixth temperature difference is less than the first temperature threshold value, which is not specifically limited here. In the judgment process of the step S44, the case that the sixth temperature difference is equal to the first temperature threshold value is attributed to the case that the sixth temperature difference is less than the first temperature threshold value.

[0172] S45, determining whether the sixth temperature difference is greater than the first temperature threshold value.

[0173] When it is determined that the sixth temperature difference is greater than the first temperature threshold value, the step S41 is performed; when it is determined that the sixth temperature difference is not greater than the first temperature threshold value, the step S47 is performed.

[0174] When the fourth humidity difference is determined to be greater than the second humidity threshold value, i.e. the indoor humidity is in the range above the maximum value in the user demand range (between the sum of the first humidity threshold value and the indoor set humidity and the sum of the second humidity threshold value and the indoor set humidity), since the air conditioner is currently still in the cooling mode or the dehumidifying mode, it is also necessary to ensure that the indoor temperature will not be lower than the minimum value in the user demand range (between the sum of the first temperature threshold value and the indoor set temperature and the sum of the second temperature threshold value and the indoor set temperature); once the indoor temperature is lower than the minimum value in the user demand range, the air conditioner needs to be controlled to stop running in the cooling mode or the dehumidifying mode in time. Therefore, the step S45 needs to be performed.

[0175] It should be noted that the sixth temperature difference being equal to the second temperature threshold value is a critical case, which can be attributed to the case that the sixth temperature difference is greater than the second temperature threshold value or the case that the sixth temperature difference is less than the second temperature threshold value, which is not specifically limited here. In the judgment process of the step S45, the case that the sixth temperature difference is equal to the second temperature threshold value is attributed to the case that the sixth temperature difference is less than the second temperature threshold value.

[0176] S46, calculating the second dew point temperature of the indoor corresponding to the air conditioner according to the sixth indoor temperature and the fifth indoor humidity.

[0177] The step S46 is followed by the step S48.

[0178] The second dew point temperature of the indoor corresponding to the air conditioner is calculated according to the sixth indoor temperature and the fifth indoor humidity, and the calculation is specifically based on the formula (1) as described above.

[0179] S47, controlling the outdoor unit of the air conditioner to stop running, and controlling the indoor unit of the air conditioner to run in the air supply mode.

[0180] When the step S47 is executed, it indicates that the indoor temperature and the indoor humidity meet the user's demand, or the indoor temperature and the indoor humidity are close to the user's demand, and cannot be made closer to the user's demand by the cooling mode or the dehumidification mode; at this time, the air conditioner only needs to function as a fan.

[0181] S48, calculating a second condensation temperature difference between the second dew point temperature and the second saturation temperature.

[0182] S49, judging whether the second condensation temperature difference is greater than a fifth temperature threshold.

[0183] When it is determined that the second condensation temperature difference is greater than the fifth temperature threshold, S410 is executed; when it is determined that the second condensation temperature difference is not greater than the fifth temperature threshold, S44 is executed. Exemplarily, the fifth temperature threshold can be 5℃ (only as an example, other values greater than zero can also be taken).

[0184] The purpose of the step S49 is that the greater the difference between the temperature of the indoor heat exchanger and the indoor dew point temperature, the more likely it is to cause the water vapor in the indoor air to condense, thereby reducing the indoor humidity. Therefore, when it is determined that the current indoor humidity has met the user's demand (between the sum of the first humidity threshold and the indoor set humidity and the sum of the second humidity threshold and the indoor set humidity), and the difference between the current indoor temperature and the indoor set temperature is greater than the second temperature threshold, in order to reduce the condensation of water vapor in the indoor air as much as possible (i.e., to avoid the reduction of indoor humidity as much as possible) when reducing the indoor temperature, it is necessary to avoid that the temperature of the indoor heat exchanger is much lower than the dew point temperature of the indoor (greater than the fifth temperature threshold), so it is necessary to do S49 judgment. If the second condensation temperature difference is greater than the fifth temperature threshold, subsequent corresponding control (step S410) is needed to make the second condensation temperature difference less than the fifth temperature threshold, so as to reduce the condensation speed of water vapor in the indoor air.

[0185] S410, reducing the operating frequency of the compressor of the air conditioner.

[0186] After S410, S49 is executed.

[0187] Specifically, the amount of refrigerant input into the indoor heat exchanger can directly affect the refrigeration, heating and dehumidification effects, and the amount of refrigerant input depends on the operating frequency of the compressor. When the operating frequency of the compressor is high, the amount of refrigerant discharged into the air conditioner refrigerant circulation system is also large, so that the amount of refrigerant flowing through the indoor heat exchanger also increases, thereby playing a role in accelerating the refrigeration, heating and dehumidification efficiency. When the operating frequency of the compressor is low, the amount of refrigerant discharged into the air conditioner refrigerant circulation system is also small, so that the amount of refrigerant flowing through the indoor heat exchanger also decreases, thereby playing a role in delaying the refrigeration, heating and dehumidification process. Therefore, in order to reduce the speed of reducing indoor humidity (the condensation speed of water vapor in indoor air) when the air conditioner is running in the refrigeration mode or the dehumidification mode, the operating frequency of the compressor needs to be reduced.

[0188] In order to prevent the stable operation of the compressor, the frequency cannot be reduced too much each time and cannot be reduced below the preset minimum operating frequency, so S410 specifically includes: when the current operating frequency of the compressor is not greater than the sum of the minimum operating frequency and the preset step value, the operating frequency of the compressor is not changed; when the current operating frequency of the compressor is greater than the sum of the minimum operating frequency and the preset step value, the operating frequency of the compressor is reduced by the preset step value. Exemplarily, the preset step value can be 10 Hz (only as an example, which can be other values greater than zero).

[0189] Further optionally, the greater the speed of the indoor fan, the faster the indoor air circulates in the indoor unit, and the faster the circulation, the shorter the time of contact between the indoor air and the indoor heat exchanger, and the indoor air vapor also does not have sufficient time to condense on the indoor heat exchanger, which is equivalent to reducing the speed of condensation of water vapor in the indoor air (the speed of reducing indoor humidity). At the same time, the faster the wind speed, the water droplets condensed on the indoor heat exchanger can also be blown out of the indoor unit to evaporate in the room, which further reduces the speed of condensation of water vapor in the indoor air (the speed of reducing indoor humidity). Therefore, S410 further includes: increasing the speed of the indoor fan of the air conditioner. Specifically, increasing the speed of the indoor fan of the air conditioner can be increasing the speed of the indoor fan by a target value or increasing the speed of the indoor fan by one gear. For example, increasing the speed of the indoor fan by 200 r / min (target value, only as an example). For another example, if the current speed of the indoor fan corresponds to a low speed gear, the speed of the indoor fan is increased to a medium speed gear (only as an example, which can also be a high speed gear, etc.).

[0190] It should be noted that when the air conditioner itself is provided with a humidifying device, in order to further ensure that the indoor humidity meets the user's demand for humidity, the step S47 can further include: obtaining the current indoor humidity, and when it is determined that the difference between the current indoor humidity and the indoor set humidity is not between the first humidity threshold and the second humidity threshold, controlling the humidifying device to work until the difference between the current indoor humidity and the indoor set humidity is between the first humidity threshold and the second humidity threshold.

[0191] In the technical scheme provided by the embodiment of the application, when it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity meet the fourth preset condition, that is, when the current indoor temperature is not too low (not less than the sum of the first temperature threshold and the indoor set temperature) and the indoor humidity is too high (greater than the sum of the second humidity threshold and the indoor set humidity), after the air conditioner is controlled to run in the cooling mode or the dehumidifying mode to reduce the indoor humidity to the user demand range, if the temperature is still in the range above the maximum value in the user demand range, the difference between the temperature of the indoor heat exchanger and the dew point temperature of the indoor air is small through the control of the frequency of the compressor, so as to prevent the water vapor in the indoor air from condensing too fast, and the indoor humidity is also prevented from being reduced too much when the indoor temperature reaches the user demand range (greater than the sum of the first temperature threshold and the indoor set temperature and less than the sum of the second temperature threshold and the indoor set temperature). Therefore, the technical scheme provided by the embodiment of the application can meet the user's demand from both the temperature and the humidity when the air conditioner is controlled, and the user experience is improved.

[0192] In an implementable manner, referring to FIG. 5, when the target temperature and humidity double-control mode is the fifth temperature and humidity double-control mode, the step 305 specifically includes: Figure 11

[0193] S51, control the outdoor unit of the air conditioner to stop running, and control the indoor unit of the air conditioner to run in the air supply mode.

[0194] Because the indoor temperature in the indoor environment corresponding to the fifth temperature and humidity double-control mode is in the user demand range (between the sum of the first humidity threshold and the indoor set humidity and the sum of the second humidity threshold and the indoor set humidity), and the indoor humidity is not too high (not greater than the sum of the second humidity threshold and the indoor set humidity), the indoor environment also meets the user demand in a certain sense; and because most air conditioners cannot increase the indoor humidity, in this case, the air conditioner can only be controlled to only function as a fan. In the case where the humidity cannot be changed, the user's demand for temperature is ensured, and the user experience is improved.

[0195] ​It should be noted that when the air conditioner itself is provided with a humidifying device, in order to further ensure that the indoor humidity meets the user's demand for humidity, the step S51 can further include: obtaining the current indoor humidity, and when it is determined that the difference between the current indoor humidity and the indoor set humidity is not between the first humidity threshold and the second humidity threshold, controlling the humidifying device to work until the difference between the current indoor humidity and the indoor set humidity is between the first humidity threshold and the second humidity threshold.

[0196] In the technical scheme provided in the present application, when it is determined that the difference between the current indoor temperature and the indoor set temperature and the difference between the indoor humidity and the indoor set humidity meet the fifth preset condition, it means that the indoor humidity in the current indoor environment is not too high (less than the sum of the second humidity threshold and the indoor set humidity) and the indoor temperature is appropriate (greater than the sum of the first temperature threshold and the indoor set temperature and less than the sum of the second temperature threshold and the indoor set temperature), at this time, the indoor environment basically meets the user's demand, so at this time, the air conditioner is controlled to only play the role of a fan in the indoor environment, which can ensure that the user's demand for the indoor temperature is met.

[0197] Optionally, after the air conditioner executes the target temperature and humidity double-control mode for a period of time, it is very likely that the air conditioner plays the role of a fan in the indoor environment, and if the air conditioner only acts as a fan for a long time, the indoor environment will change with the actual change of the external environment, so additional control is needed, and therefore, as shown in Figure 12 The technical scheme provided in the embodiment of the present application further includes 306-310 after the step 305.

[0198] 306. After the air conditioner executes the target temperature and humidity double-control mode for a preset period of time, the second indoor temperature and the second indoor humidity corresponding to the air conditioner are obtained.

[0199] 307. The second temperature difference between the second indoor temperature and the indoor set temperature and the second humidity difference between the second indoor humidity and the indoor set humidity are calculated.

[0200] 308. It is judged whether the second temperature difference is greater than the first temperature threshold and less than the second temperature threshold.

[0201] When it is determined that the second temperature difference is greater than the first temperature threshold and less than the second temperature threshold, 309 is executed; when it is determined that the second temperature difference is not greater than the first temperature threshold or not less than the second temperature threshold, 310 is executed.

[0202] The significance of 306-308 is that after the air conditioner executes the target temperature and humidity double-control mode for a period of time, it is further needed to determine whether the current indoor environment meets the indoor environment required by the user (Table 1 and Figure 4If the second temperature difference is equal to the first temperature threshold, it means that the indoor environment corresponding to the middle E zone is in a critical state, and if it is met, the air conditioner can continue to be used as a fan, and if it is not met, the target temperature and humidity double control mode needs to be reselected and executed, so the steps 306-308 need to be performed.

[0203] It should be noted that the second temperature difference equal to the first temperature threshold is a critical case, which can be attributed to the case that the second temperature difference is less than the first temperature threshold, or the case that the second temperature difference is greater than the first temperature threshold, which is not limited here. The second temperature difference equal to the second temperature threshold is the same. In the judgment process of 308, the second temperature difference equal to the first temperature threshold is attributed to the case that the second temperature difference is less than the first temperature threshold, and the second temperature difference equal to the second temperature threshold is attributed to the case that the second temperature difference is greater than the second temperature threshold.

[0204] 309, control the outdoor unit of the air conditioner to stop running, and control the indoor unit of the air conditioner to run in the air supply mode.

[0205] After 309, 302 is executed.

[0206] 310, obtain the indoor temperature corresponding to the air conditioner as the first indoor temperature, and obtain the indoor humidity corresponding to the air conditioner as the first indoor humidity.

[0207] After 310, 303 is executed.

[0208] The control method of the air conditioner provided by the embodiment of the application specifically includes: first, obtaining the requirements of the user for the temperature and humidity of the indoor corresponding to the air conditioner, i.e., the indoor set temperature and the indoor set humidity, then obtaining the first indoor temperature and the first indoor humidity, and calculating the first temperature difference between the first indoor temperature and the indoor set humidity and the first humidity difference between the first indoor humidity and the indoor set humidity, then selecting the corresponding target temperature and humidity double control mode from the pre-set multiple temperature and humidity double control modes according to the conditions that can be met by the specific values of the first temperature difference and the first humidity difference, and finally executing the target temperature and humidity double control mode. Because in the technical solution provided by the present application, when the air conditioner is controlled, the difference between the temperature required by the user and the actual temperature in the room and the difference between the humidity required by the user and the actual humidity in the room are fully considered. Differentiation of any one of the two types of differences will result in different selection of the temperature and humidity double control mode. Not only the control mode of the air conditioner is set from the temperature adjustment aspect, but also the control mode of the air conditioner is set from the humidity adjustment aspect. Therefore, the result of the final operation of the air conditioner can be maximized to the direction of the temperature and humidity required by the user, i.e., to meet the user's demand not only from the temperature aspect but also from the humidity aspect, thereby improving the user's experience.

[0209] In order to better implement the control method of the air conditioner provided in the above embodiments, refer to Figure 13As shown, the embodiment of the present application further provides a possible structural diagram of the control device 23 of the air conditioner, which comprises: an acquisition module 231, a calculation module 232, a processing module 233 and a control module 234.
