Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0101] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0102] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all couplings of one or more related listed items.

[0103] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0104] At present, when variable frequency air conditioners adjust the temperature, they mostly collect the ambient temperature and adjust the wind speed according to the ambient temperature. However, the adjustment of wind speed can only control the working mode of the fan, but cannot effectively control the compressor of the air conditioner, which not only makes it impossible to accurately control the temperature, but also cannot ensure the energy efficiency of the air conditioner.

[0105] In view of this, the present application provides an air conditioning air supply method, which forms a difference by comparing the temperature environment in the upper and lower parts of the room with the preset temperature, and then divides a plurality of temperature intervals according to the difference, and associates each temperature interval with the actions of the upper air outlet, the lower air outlet and the internal air guide plate, and limits the maximum operating frequency for different temperature intervals. The greater the temperature difference, the higher the operating frequency of the compressor, and the smaller the temperature difference, the lower the operating frequency of the compressor, thereby ensuring the energy efficiency of the air conditioner while reducing the risk of condensation.

[0106] The air conditioner used in the present application is a distributed air supply air conditioner, that is, the air conditioner has an upper air outlet and a lower air outlet, and there are wind guide plates or wind sweeping components inside the air conditioner that can change the air outlet effect. There are two temperature detection devices in the air conditioner, which are respectively located at the upper part of the air inlet and the lower part of the air inlet, corresponding to the upper air inlet and the lower air inlet, which are used to detect the ambient temperature of the upper part of the room and the ambient temperature of the lower part of the room. The air conditioner in the present application can have only one air inlet, in which case the two temperature sensors can be located at the upper part and the lower part of the air inlet, respectively. The air conditioner in the present application can also have two upper and lower air inlets, in which case the two temperature detection devices can be located at the upper part of the upper air inlet and the lower part of the lower air inlet, respectively, or respectively located at the upper part of the upper air inlet and between the upper air inlet and the lower air inlet. The air conditioner can be a cabinet unit or other wall mounted units, window units, etc. with upper and lower air outlets.

[0107] like Figure 1 As shown, an embodiment of the present application provides an air conditioning air supply method, the method comprising:

[0108] S100, obtaining the upper ambient temperature and the lower ambient temperature of the room.

[0109] Specifically, the upper ambient temperature and the lower ambient temperature of the room can be measured by different temperature sensors. For example, the temperature sensors can be distributed at the upper and lower parts of the air inlet of the air conditioner indoor unit, and can also be arranged at the top and bottom of the room as needed.

[0110] S102, determining a first temperature difference between the upper ambient temperature and a target temperature and a second temperature difference between the lower ambient temperature and the target temperature.

[0111] Specifically, the collected upper and lower ambient temperatures are compared with the preset temperature set by the user, and the difference is calculated. The target temperature represents the temperature that the user sets and hopes to achieve.

[0112] S104: Determine an air supply mode for a current air supply stage according to at least one of the first temperature difference and the second temperature difference.

[0113] Specifically, these differences can be compared with preset thresholds to determine whether the current temperature state needs to be adjusted. In the case where the current temperature state needs to be adjusted, the air supply mode of the air conditioner is determined according to the threshold interval of the first difference and the second difference. The air supply mode includes the air supply method of the air supply component. The air supply component includes a first air supply component and a second air supply component, the first air supply component includes an upper air outlet and an upper air sweeping component, and the second air supply component includes a lower air outlet and a lower air sweeping component.

[0114] Through the above method, the ambient temperatures of the upper and lower parts of the room can be accurately controlled according to the first temperature difference and the second temperature difference, thereby achieving accurate control of the overall temperature of the room.

[0115] In addition, in some implementations, the temperature difference between different areas of the room (for example, the upper and lower parts of the room) can be reduced to improve the comfort of the user. In addition, in some implementations, the operating frequency of the compressor can be dynamically adjusted according to the temperature difference, and different maximum operating frequencies of the compressor can be set to correspond to different room temperature differences to achieve energy saving effects, and reduce the risk of condensation in cooling mode. This will be explained in detail below.

[0116] Optionally, in an implementation of this embodiment, when one of the first temperature difference and the second temperature difference is adjusted in the current air supply stage, the other of the first temperature difference and the second temperature difference is adjusted in the next air supply stage.

[0117] For example, if the current air supply stage aims to adjust the first temperature difference to a set target range or target value, the next stage of the current air supply stage aims to adjust the second temperature difference to a set target range or target value. Through this staged adjustment, with different adjustment objects in each stage, the temperature difference between different areas of the room can be effectively reduced, improving user comfort.

[0118] Optionally, in an implementation of this embodiment, in cooling mode, the next air supply stage is regulated in such a way that the adjustment object of the next air supply stage becomes lower than the value in the current air supply stage. Alternatively, in heating mode, the next air supply stage is regulated in such a way that the adjustment object of the next air supply stage becomes higher than the value in the current air supply stage. In this way, the target temperature can be reached stably. For detailed description of this, please refer to Figure 2 and Figure 3 The embodiment shown.

[0119] Optionally, in an implementation of this embodiment, the air supply mode also includes the working state of the compressor of the air conditioner; wherein the working state of the compressor corresponds to the air supply mode of the air supply component. For example, if the air supply volume of the air supply mode is larger, the working frequency of the compressor is higher, and vice versa, the lower it is or even does not work. The correspondence between the air supply volume and the compressor frequency is conducive to achieving the purpose of temperature control while saving energy.

[0120] Optionally, in an implementation of this embodiment, S104 includes any one or more of the following possibilities.

[0121] Possibility one: when the main temperature difference between the first temperature difference and the second temperature difference is in the first main interval, the air supply mode of the current air supply stage is determined to be the first air supply mode according to the main temperature difference.

[0122] Possibility 2: When the main temperature difference of the first temperature difference and the second temperature difference is in the second main interval and the auxiliary temperature difference is in the first auxiliary interval, the air supply mode of the current air supply stage is determined to be the second air supply mode according to the main temperature difference and the auxiliary temperature difference.

[0123] Possibility three: when the main temperature difference of the first temperature difference and the second temperature difference is in the second main interval and the auxiliary temperature difference is in the second auxiliary interval, the air supply mode of the current air supply stage is determined to be the third air supply mode according to the main temperature difference and the auxiliary temperature difference.

[0124] Possibility four: when the main temperature difference of the first temperature difference and the second temperature difference is in the third main interval and the auxiliary temperature difference is in the second auxiliary interval, the air supply mode of the current air supply stage is determined to be the fourth air supply mode according to the main temperature difference and the auxiliary temperature difference.

[0125] In the above possibilities, in cooling mode, the main temperature difference is the first temperature difference, the secondary temperature difference is the second temperature difference, the values ​​of the first main interval, the second main interval and the third main interval decrease in sequence, and the values ​​of the first secondary interval and the second secondary interval decrease in sequence; wherein, in heating mode, the main temperature difference is the second temperature difference, the secondary temperature difference is the first temperature difference, the values ​​of the first main interval, the second main interval and the third main interval increase in sequence, and the values ​​of the first secondary interval and the second secondary interval increase in sequence. In this way, during the heating and cooling processes, the influence of the temperature difference in different indoor areas on human comfort is taken into account, and the comfort level is improved by reducing the temperature difference in different indoor areas.

[0126] Optionally, in this implementation, the air volume of the air supply modes in the first air supply mode, the second air supply mode, the third air supply mode, and the fourth air supply mode gradually decreases. Or, the air volume of the air supply modes in the first air supply mode, the second air supply mode, and the third air supply mode gradually decreases, and the air volume of the air supply modes in the third air supply mode and the fourth air supply mode is the same. Or, the operating frequency of the compressor in the first air supply mode, the second air supply mode, the third air supply mode, and the fourth air supply mode gradually decreases, and / or the operating frequency of the compressor in the fourth air supply mode is 0.

[0127] More specifically, in the first air supply mode, the main temperature difference is adjusted in such a way that the air supply volume of the auxiliary air supply component is balanced with or greater than the air supply volume of the main air supply component, so as to make the main temperature difference enter the second main interval from the first main interval. The "balanced with" means that the air supply volume of the auxiliary air supply component and the air supply volume of the main air supply component are not deliberately adjusted to make a difference between the two. For example, "balanced with" includes: both the upper air outlet and the lower air outlet supply air, and both the upper air sweeping component and the lower air sweeping component sweep air within the sweepable air range allowed by the hardware.

[0128] In the second air supply mode, the auxiliary air supply component supplies more air than the main air supply component and the auxiliary air supply component performs air supply disturbance, so as to adjust the auxiliary temperature difference from the first auxiliary interval to the second auxiliary interval.

[0129] In the third air supply mode, the main temperature difference is adjusted for the purpose of making the main temperature difference enter the third main interval from the second main interval, with the third air supply method in which the air supply volume of the auxiliary air supply component is greater than the air supply volume of the main air supply component.

[0130] In the fourth air supply mode, the main temperature difference is adjusted for the purpose of maintaining the secondary temperature difference in the second secondary interval in a fourth air supply manner in which the air supply volume of the secondary air supply component is greater than the air supply volume of the main air supply component.

[0131] In the above-mentioned various air supply modes, in cooling mode, the second air supply component is the main air supply component, and the first air supply component is the auxiliary air supply component; in heating mode, the first air supply component is the main air supply component, and the second air supply component is the auxiliary air supply component.

[0132] More specifically, in the second air supply mode, the second air supply mode includes: the lower air outlet is closed, the upper air outlet is opened, and the upper air sweeping component sweeps air. In the third air supply mode, the third air supply mode includes: the lower air outlet is closed, the upper air outlet is opened, and the upper air sweeping component does not sweep air and is in the minimum air outlet position. In the fourth air supply mode, the fourth air supply mode is the same as the third air supply mode. The operating frequency of the compressor in the second air supply mode is greater than the operating frequency of the compressor in the third air supply mode, and the compressor in the fourth air supply mode does not work.

[0133] Optionally, in this implementation, when the main temperature difference between the first temperature difference and the second temperature difference is in the first main interval, determining the air supply mode of the current air supply stage as the first air supply mode according to the main temperature difference includes the following situations:

[0134] When the main temperature difference between the first temperature difference and the second temperature difference is in the first sub-main interval, the air supply mode of the current air supply stage is determined to be the first sub-air supply mode according to the main temperature difference.

[0135] When the main temperature difference between the first temperature difference and the second temperature difference is in the second sub-main interval, the air supply mode of the current air supply stage is determined to be the second sub-air supply mode according to the main temperature difference.

[0136] In the heating mode, the value of the second sub-main interval is greater than the value of the first sub-main interval, and in the cooling mode, the value of the second sub-main interval is less than the value of the first sub-main interval.

[0137] By adopting this implementation method, when the main temperature difference is large, through staged temperature control, the temperature is quickly approached to the target temperature based on the first sub-air supply mode, and the temperature difference between different upper and lower areas is controlled while quickly approaching the target temperature based on the second sub-air supply mode, so that the first air supply mode takes into account both temperature control efficiency and temperature control comfort.

[0138] More specifically, the total air supply volume of the first sub-air supply mode is greater than the total air supply volume of the second sub-air supply mode; the compressor operating frequency of the first sub-air supply mode is greater than the compressor operating frequency of the second sub-air supply mode.

[0139] In the first sub-air supply mode, the first sub-air supply mode is used in which the air supply volume of the auxiliary air supply component is balanced with the air supply volume of the main air supply component and both the auxiliary air supply component and the main air supply component perform air supply disturbance, so as to adjust the main temperature difference from the first sub-main interval to the second sub-main interval.

[0140] In the second sub-air supply mode, the second sub-air supply mode is adopted in which the air supply volume of the auxiliary air supply component is greater than the air supply volume of the main air supply component and the auxiliary air supply component performs air supply disturbance, so as to adjust the main temperature difference from the first sub-main interval to the second sub-main interval.

[0141] Optionally, in this implementation, in cooling mode, the value of the third main interval is a negative value (for example, the lower ambient temperature is slightly lower than the target temperature), and the value of the second sub-interval is a positive value (for example, the upper ambient temperature is slightly higher than the target temperature); in heating mode, the value of the third main interval is a positive value (for example, the upper ambient temperature is slightly higher than the target temperature), and the value of the second sub-interval is a sub-value (for example, the lower ambient temperature is slightly lower than the target temperature). In this way, by coordinating the upper and lower ambient temperatures, the overall ambient temperature reaches the target temperature while reducing the temperature difference between the upper and lower ambient temperatures, thereby improving comfort.

[0142] The embodiment of the present application also provides an air supply method for an air conditioner. The air conditioner includes an air supply component, the air supply component includes a first air supply component and a second air supply component, the first air supply component includes an upper air outlet and an upper air sweeping component, and the second air supply component includes a lower air outlet and a lower air sweeping component. In the process of controlling the indoor temperature to reach the target temperature, the method has a temperature balancing process of adjusting the indoor temperature according to the first temperature difference and the second temperature difference. The first temperature difference is the temperature difference between the upper ambient temperature of the room and the target temperature, and the second temperature difference is the temperature difference between the lower ambient temperature of the room and the target temperature.

[0143] By adopting this embodiment, a temperature equalization process is introduced into the temperature control process for the purpose of achieving the target temperature, which can effectively reduce the temperature difference between the upper ambient temperature and the lower ambient temperature of the room, and at the same time make the overall ambient temperature more accurately approach the target problem, thereby improving the accuracy of temperature control and the comfort.

[0144] The temperature balancing process includes: when the main temperature difference of the first temperature difference and the second temperature difference is in the first target interval, controlling the air supply mode so that the secondary temperature difference of the first temperature difference and the second temperature difference is in the second target interval, thereby reducing the temperature difference between the upper ambient temperature of the room and the lower ambient temperature of the room. In other words, the first target interval and the second target interval are designed to reduce the temperature difference between the upper ambient temperature of the room and the lower ambient temperature of the room.

[0145] Wherein, the air supply mode includes the air supply mode of the air supply component. In cooling mode, the main temperature difference is the first temperature difference, and the auxiliary temperature difference is the second temperature difference; in heating mode, the main temperature difference is the second temperature difference, and the auxiliary temperature difference is the first temperature difference.

[0146] With this embodiment, multiple air supply modes are alternately controlled according to the difference between the upper and lower temperatures of the room and the set temperature, so as to achieve a long-term temperature control effect with low temperature fluctuation. In addition, by setting different maximum operating frequencies of the compressor to correspond to different room temperature differences, energy saving effects can be achieved, and the risk of condensation can be reduced in cooling mode.

[0147] Optionally, in an implementation of this embodiment, when the main temperature difference is in the first target interval, the ambient temperature corresponding to the main temperature difference does not reach the target temperature, and when the secondary temperature difference is in the second target interval, the ambient temperature corresponding to the secondary temperature difference does not reach the target temperature, and the ambient temperature corresponding to the secondary temperature difference is farther from the target temperature. Or, when the main temperature difference is in the first target interval, the ambient temperature corresponding to the main temperature difference reaches the target temperature, and when the secondary temperature difference is in the second target interval, the ambient temperature corresponding to the secondary temperature difference does not reach the target temperature. With this implementation, both the upper ambient temperature and the lower ambient temperature are taken into account during the indoor temperature control process.

[0148] Optionally, in an implementation of this embodiment, the auxiliary air supply component supplies more air than the main air supply component and the auxiliary air supply component performs air supply disturbance (for example, the second air supply method mentioned above), and the auxiliary temperature difference in the first temperature difference and the second temperature difference is controlled to be in the second target range. In the cooling mode, the second air supply component is the main air supply component, and the first air supply component is the auxiliary air supply component. In the heating mode, the first air supply component is the main air supply component, and the second air supply component is the auxiliary air supply component.

[0149] Optionally, in an implementation of this embodiment, before the temperature equalization process, the method further includes: when a main temperature difference between the first temperature difference and the second temperature difference is in a first main interval, determining to adopt a first air supply mode according to the main temperature difference.

[0150] Alternatively, when the main temperature difference between the first temperature difference and the second temperature difference is within the first target range, the air supply mode is controlled so that the secondary temperature difference between the first temperature difference and the second temperature difference is within the second target range, including: when the main temperature difference between the first temperature difference and the second temperature difference is within the first target range (i.e., the second main range) and the secondary temperature difference is within the first secondary range, determining to adopt the second air supply mode according to the main temperature difference and the secondary temperature difference.

[0151] Alternatively, after the temperature equalization process, the method further includes: when the main temperature difference between the first temperature difference and the second temperature difference is in the first target interval and the secondary temperature difference is in the second target interval (i.e., the second secondary interval), determining to adopt a third air supply mode according to the main temperature difference and the secondary temperature difference; and / or, when the main temperature difference between the first temperature difference and the second temperature difference is in the third main interval and the secondary temperature difference is in the second secondary interval, determining the air supply mode of the current air supply stage as the fourth air supply mode according to the main temperature difference and the secondary temperature difference.

[0152] In this implementation, in cooling mode, the main temperature difference is the first temperature difference, the auxiliary temperature difference is the second temperature difference, the values ​​of the first main interval, the first target interval (i.e., the second main interval) and the third main interval decrease in sequence, and the values ​​of the first auxiliary interval and the second target interval (i.e., the second auxiliary interval) decrease in sequence. In heating mode, the main temperature difference is the second temperature difference, the auxiliary temperature difference is the first temperature difference, the values ​​of the first main interval, the first target interval and the third main interval increase in sequence, and the values ​​of the first auxiliary interval and the second target interval increase in sequence.

[0153] In this implementation, for detailed descriptions of the first air supply mode, the second air supply mode, the third air supply mode, and the fourth air supply mode, please refer to Figure 1 The description in the illustrated embodiment will not be repeated here.

[0154] In order to more clearly understand the embodiments of the present application, Figure 2 A schematic flow chart of an air conditioning air supply method during a refrigeration process according to an embodiment of the present application is provided. Figure 2 , including the following processing steps.

[0155] a. When the refrigeration is turned on, the upper and lower air-discharging variable frequency cabinet delivers air in mode A (i.e., the air-discharging mode of the first sub-air-discharging mode), and the maximum operating frequency of the compressor is limited to A1 (i.e., the working state of the compressor in the first sub-air-discharging mode); and in the process, it is determined whether the difference between the current air inlet temperature at the bottom of the indoor unit and the set temperature (i.e., the second temperature difference, the main temperature difference) is less than or equal to the set threshold value T1. If so (i.e., the second temperature difference is in the second sub-main interval, the second sub-main interval = (T2, T1]), then proceed to step b; otherwise (i.e., the second temperature difference is in the first sub-main interval, the first sub-main interval = (T1, ∞)), the variable frequency air-conditioning cabinet still delivers air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0156] b. The air conditioner now supplies air in mode B (i.e., the air supply mode of the second sub-air supply mode), and the maximum operating frequency of the compressor is limited to B1 (i.e., the working state of the compressor in the second sub-air supply mode). And continue to determine whether the difference between the current air inlet temperature at the bottom of the indoor unit and the set temperature (i.e., the second temperature difference, the main temperature difference) is less than or equal to the set threshold value T2. If so (i.e., the second temperature difference is located in the second main interval, the second main interval = (T3, T2]), then enter step c; otherwise (i.e., the second temperature difference is located in the second sub-main interval, the second sub-main interval = (T2, T1]), continue to determine whether the difference between the current air inlet temperature at the top of the indoor unit and the set temperature is less than or equal to the set threshold value T4. If so, the air conditioner supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1. Otherwise, continue to determine whether the difference between the current air inlet temperature at the bottom of the indoor unit and the set temperature is less than or equal to the set threshold value T1. If so, the air conditioner supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1. Otherwise, enter step a.

[0157] c. The air conditioner now supplies air in mode C (i.e., the air supply mode of the second air supply mode), and the maximum operating frequency of the compressor is limited to C1 (i.e., the working state of the compressor in the second air supply mode); and continues to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature (i.e., the first temperature difference, the sub-temperature difference) is less than or equal to the set threshold value T1. If so (i.e., the first temperature difference belongs to the second sub-interval, the second sub-interval = (-∞, T1]), then enter step d, otherwise (i.e., the first temperature difference belongs to the first sub-interval, the first sub-interval = (T1, ∞)), continue to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature is less than or equal to the set threshold value T2 (here, T2 is less than T1, the purpose is to determine whether the first temperature difference has a trend of further reduction). If so, the air conditioner supplies air in mode C, and the maximum operating frequency of the compressor is limited to C1. Otherwise, continue to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature is less than or equal to the set threshold value T1. If so, the air conditioner supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1. Otherwise, enter step a.

[0158] d. The air conditioner now supplies air in mode D (i.e., the air supply mode of the third air supply mode), and the maximum operating frequency of the compressor is limited to D1 (i.e., the working state of the compressor in the third air supply mode); and continues to determine whether the current lower air inlet temperature of the indoor unit and the set temperature difference (i.e., the second temperature difference, the main temperature difference) are less than or equal to the set threshold value T3. If (that is, the second temperature difference belongs to the third main interval, the third main interval = (-∞, T3]), then enter step e; otherwise, continue to determine whether the difference between the current upper air inlet temperature of the indoor unit and the set temperature is less than or equal to the set threshold value T2. If so, the air conditioner supplies air in mode D, and the maximum operating frequency of the compressor is limited to D1. Otherwise, continue to determine whether the difference between the current lower air inlet temperature of the indoor unit and the set temperature is less than or equal to the set threshold value T2. If so, the air conditioner supplies air in mode C, and the maximum operating frequency of the compressor is limited to C1. Otherwise, continue to determine whether the difference between the current lower air inlet temperature of the indoor unit and the set temperature is less than or equal to the set threshold value T1. If so, the air conditioner supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1. Otherwise, enter step a.

[0159] e. The air conditioner now supplies air in mode D (i.e., the air supply mode of the fourth air supply mode, which is the same as the air supply mode of the third air supply mode), and the compressor is stopped (i.e., the compressor working state of the fourth air supply mode); and continues to determine whether the current air inlet temperature on the indoor unit and the set temperature difference (i.e., the first temperature difference, the sub-temperature difference) are less than or equal to the set threshold value T1. If so (i.e., the second sub-interval = (-∞, T1], or, the second sub-interval = [T2, T1]), the air conditioner now supplies air in mode D, and the compressor is stopped. Otherwise, enter step c.

[0160] It should be noted that under the above-mentioned air supply control method, the distributed variable frequency cabinet air conditioner can automatically control the opening and closing of the upper and lower air outlets and the movement of the upper and lower air guide components according to the difference between the upper and lower temperatures in the room and the set temperature. While increasing the temperature rise and temperature drop rates, it can also reduce indoor temperature fluctuations and improve the accuracy of temperature control.

[0161] In this embodiment, four air supply modes are described as follows:

[0162] Mode A air supply: The upper and lower air outlets are opened and air is supplied at the same time, and the upper and lower air sweeping components operate at the same time, which can increase the air disturbance in the room, improve the uniformity of room temperature, increase the temperature drop rate, and quickly cool the room down to close to the set temperature.

[0163] Mode B air supply: The upper and lower air outlets are opened and air is supplied at the same time, the upper air sweeping component is running, and the lower air sweeping component stops running and is in the minimum air outlet position, which can effectively reduce the wind feeling at the bottom of the air conditioner and prevent excessive vertical temperature difference in the room.

[0164] Air supply in mode C: the lower air outlet is closed, the upper air outlet is opened, only the upper air outlet supplies air, and the upper air sweeping component is running. At this time, the lower part of the room is close to the set temperature, while the upper part of the room has not reached the set temperature. Closing the lower air outlet can effectively prevent the temperature of the lower part of the room from deviating from the set temperature. At the same time, opening the upper air outlet makes the temperature of the upper part of the room continue to approach the set temperature, so that the overall temperature of the room is close to the set temperature, preventing the vertical temperature difference in the room from being too large.

[0165] D mode air supply: the lower air outlet is closed, the upper air outlet is opened, and only the upper air outlet supplies air. The upper air sweeping component stops running and is in the minimum air outlet position. At this time, the temperature of the upper part of the room is close to the set temperature, and the temperature of the lower part of the room is slightly lower than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak cold air from the upper air outlet to keep the room temperature stable.

[0166] In this embodiment, the maximum operating frequency of the compressor is set to A1>B1>C1>D1. This is mainly because on the one hand, the load in the air-conditioned room will gradually decrease, and the maximum operating frequency of the compressor can be reduced, thereby saving energy; at the same time, in the cooling mode, the lower air guide component is at the minimum air outlet position in mode B air supply, the lower air outlet is closed in mode C, and the lower air outlet is closed and the upper air guide component is at the minimum air outlet position in mode D, resulting in a reduction in the overall air output of the air conditioner. If the frequency is not changed, the air outlet temperature will be reduced. When the air outlet temperature is lower than the indoor dew point temperature, there will be a risk of condensation. Therefore, in the cooling mode, when the air supply in modes B, C, and D gradually reduces the air outlet, it is also necessary to gradually reduce the maximum operating frequency of the compressor and increase the air outlet temperature to avoid condensation.

[0167] According to research, the difference T1 can be 0 to 2, preferably 1; the difference T2 can be -1 to 1, preferably 0; the difference T3 can be -3 to -1, preferably -2; the difference T4 can be 1 to 3, preferably 2. It should be noted that the difference can also be adjusted according to actual conditions. In addition, although the same value is used for the main interval and the sub-interval in this embodiment, in other embodiments, the values ​​of the main interval and the sub-interval are not necessarily the same.

[0168] Figure 3 A schematic flow chart of an air conditioning air supply method during a refrigeration process according to an embodiment of the present application is provided. Figure 3 , including the following processing steps.

[0169] f. When the heating is turned on, the upper and lower air-discharging variable frequency cabinet units supply air in mode E (i.e., the air-discharging mode of the first sub-air-discharging mode), and the maximum operating frequency of the compressor is limited to E1 (i.e., the working state of the compressor in the first sub-air-discharging mode); and during the process, it is determined whether the temperature difference between the current air inlet on the indoor unit and the set temperature (i.e., the first temperature difference, the main temperature difference) is greater than or equal to the set threshold value Ta. If so (i.e., the first temperature difference is located in the second sub-main interval, the second sub-main interval = [Ta, Tb)), then step g is entered; otherwise (i.e., the first temperature difference is located in the first sub-interval, the first sub-interval = (-∞, Ta)), the variable frequency air-conditioning cabinet unit still supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1;

[0170] g. The air conditioner now supplies air in F mode (i.e., the air supply mode of the second sub-air supply mode), and the maximum operating frequency of the compressor is limited to F1 (i.e., the working state of the compressor in the second sub-air supply mode); and continues to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature (i.e., the first temperature difference, the main temperature difference) is greater than or equal to the set threshold value Tb. If so (i.e., the first temperature difference is located in the second main interval, the second main interval = [Tb, Tc)), then proceed to step h, otherwise (i.e., the first temperature difference is located in the second sub-main interval, the second sub-main interval = [Ta, Tb)), then continue to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature is greater than or equal to the set threshold value Td. If so, the air conditioner supplies air in F mode, and the maximum operating frequency of the compressor is limited to F1, otherwise, continue to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature is greater than or equal to the set threshold value Ta, if so, the air conditioner supplies air in F mode, and the maximum operating frequency of the compressor is limited to F1, otherwise, proceed to step f.

[0171] h. The air conditioner now supplies air in G mode (i.e., the air supply mode of the second air supply mode), and the maximum operating frequency of the compressor is limited to G1 (i.e., the working state of the compressor in the second air supply mode); and continues to determine whether the difference between the current air inlet temperature at the lower air inlet of the indoor unit and the set temperature (i.e., the second temperature difference, the sub-temperature difference) is greater than or equal to the set threshold value Ta. If so (i.e., the second temperature difference is located in the second sub-interval, the second sub-interval = [Ta, ∞)), then proceed to step i; otherwise (i.e., the second temperature difference is located in the first sub-interval, the first sub-interval = (-∞, Ta)), continue to determine whether the difference between the current air inlet temperature at the upper air inlet of the indoor unit and the set temperature is greater than or equal to the set threshold value Tb (here, Tb is greater than Ta, the purpose is to determine whether the first temperature difference has a trend of further increase). If so, the air conditioner supplies air in G mode, and the maximum operating frequency of the compressor is limited to G1. Otherwise, continue to determine whether the difference between the current air inlet temperature at the upper air inlet of the indoor unit and the set temperature is greater than or equal to the set threshold value Ta. If so, the air conditioner supplies air in F mode, and the maximum operating frequency of the compressor is limited to F1. Otherwise, proceed to step f.

[0172] i. The air conditioner now supplies air in mode H (i.e., the air supply mode of the third air supply mode), and the maximum operating frequency of the compressor is limited to H1 (i.e., the operating frequency of the third air supply mode); and continues to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature (the first temperature difference, the main temperature difference) is greater than or equal to the set threshold value Tc. If so (i.e., the first temperature difference belongs to the third main interval, the third main interval = [Tc, ∞)), then proceed to step j; otherwise (i.e., the first temperature difference belongs to the second main interval, the second main interval = [Tb, Tc)), continue to determine whether the difference between the current air inlet temperature on the indoor unit and the set temperature is greater than or equal to the set threshold value Tb. If so, the air conditioner supplies air in H mode, and the maximum operating frequency of the compressor is limited to H1. Otherwise, continue to determine whether the current temperature difference between the air inlet on the indoor unit and the set temperature is greater than or equal to the set threshold value Tb. If so, the air conditioner supplies air in G mode, and the maximum operating frequency of the compressor is limited to G1. Otherwise, continue to determine whether the current temperature difference between the air inlet on the indoor unit and the set temperature is greater than or equal to the set threshold value Ta. If so, the air conditioner supplies air in F mode, and the maximum operating frequency of the compressor is limited to F1. Otherwise, enter step f.

[0173] j. The air conditioner now supplies air in mode H (i.e., the air supply mode of the fourth air supply mode), and the compressor is stopped (i.e., the compressor working state of the fourth air supply mode); and continues to determine whether the current air inlet temperature at the lower indoor unit and the set temperature difference (i.e., the second temperature difference, the sub-temperature difference) are greater than or equal to the set threshold value Ta. If so (i.e., the second temperature difference is in the second sub-interval, the second sub-interval = [Ta, ∞) or [Ta, Tb]), the air conditioner now supplies air in mode H, and the compressor is stopped. Otherwise, enter step h.

[0174] In this embodiment, four air supply modes are described as follows:

[0175] E mode air supply: The upper and lower air outlets are opened and air is supplied at the same time, and the upper and lower air sweeping components operate at the same time, which can increase the air disturbance in the room, improve the uniformity of room temperature, increase the temperature rise rate, and make the room temperature rise quickly to approach the set temperature.

[0176] F mode air supply: The upper and lower air outlets are opened and air is supplied at the same time, the lower air sweeping component is running, and the upper air sweeping component stops running and is in the minimum air outlet position, which can effectively reduce the wind feeling on the upper part of the air conditioner and prevent excessive vertical temperature difference in the room.

[0177] G mode air supply: the upper air outlet is closed, the lower air outlet is opened, only the lower air outlet supplies air, and the lower air sweeping component is running. At this time, the upper part of the room is close to the set temperature, while the lower part of the room has not reached the set temperature. Closing the upper air outlet can effectively prevent the upper temperature of the room from deviating from the set temperature. At the same time, opening the lower air outlet makes the lower temperature of the room continue to approach the set temperature, so that the overall temperature of the room is close to the set temperature, preventing the vertical temperature difference in the room from being too large.

[0178] H mode air supply: the upper air outlet is closed, the lower air outlet is opened, and air is supplied only from the lower air outlet. The lower air sweeping component stops running and is in the minimum air outlet position. At this time, the temperature in the lower part of the room is close to the set temperature, the temperature in the upper part of the room is slightly higher than the set temperature, and the overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak hot air from the lower air outlet to keep the room temperature stable.

[0179] In this embodiment, the maximum operating frequency of the compressor is set to E1>F1>G1>H1, mainly because on the one hand, the load in the air-conditioned refrigeration room will gradually decrease, and the maximum operating frequency of the compressor can be reduced, thereby saving energy.

[0180] According to research, the difference Ta can be -2 to 0, preferably -1; the difference Tb can be -1 to 1, preferably 0; the difference Tc can be 1 to 3, preferably 2; the difference Td can be -3 to -1, preferably -2. It should be noted that the difference can also be adjusted according to actual conditions. In addition, although the same value is used for the main interval and the sub-interval in this embodiment, in other embodiments, the values ​​of the main interval and the sub-interval are not necessarily the same.

[0181] It should be noted that the ∞ and -∞ mentioned above only mean that there is no limit on the limit values ​​in theory, but those skilled in the art know clearly that in the cooling and heating modes in the air-conditioning field, there are usually actual values. For example, the heating of household air conditioners usually does not exceed 30°C, and the cooling is usually not lower than 20°C.

[0182] The embodiment of the present application also provides an electronic device, which may be an integrated chip or a PCB board or other hardware products.
