DETAILED DESCRIPTION

[0045] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] Considering that air conditioners (such as those with separate upper and lower air flow) have multiple air supply modes, operation is cumbersome, and inconvenient for users. For example, the left and right air flow components of conventional air conditioners only have two modes: on / off. However, the left and right air flow blades of separate upper and lower air flow air conditioners have four air flow modes: up / down closed, up / down closed, up / down closed, and up / down open. Adding the upper and lower air flow components, the air flow modes are even more numerous. With so many separate air flow blade control modes, users are cumbersome and inconvenient to switch between.

[0047] Moreover, a single air supply mode cannot take into account both temperature comfort and wind comfort. For example, taking the cooling mode as an example, when the air conditioner is just turned on, in order to increase the indoor air disturbance and improve the heat exchange efficiency, the user usually needs to turn on the air guide component. At this time, the indoor temperature is relatively high, and the cold air blown out by the air conditioner will not cause obvious discomfort to the user. However, after the air conditioner has been running for a period of time, the indoor temperature is close to the set temperature. At this time, the operation of the air guide blades will blow cold air onto the user, causing discomfort in the wind. Therefore, it is necessary to adjust the air guide blades and switch the air guide mode so that the cold air cannot blow directly onto the user. In other words, as the air conditioner is running, a single air guide mode cannot take into account both the user's temperature comfort and wind comfort.

[0048] Therefore, the present invention proposes a method for controlling an air conditioner, specifically an automatic air supply control method for an air conditioner with separate upper and lower air flow guides. The method adjusts the air supply mode of the air conditioner based on the comparison between the ambient temperature and the set temperature in the upper and lower parts of the room, and the difference between the inlet temperature and the average temperature at different inlet angles, thereby facilitating user operation and improving user comfort. The present invention's primary purpose is to facilitate user operation while achieving high-precision overall room temperature control, preventing excessive local temperature differences in the room and significantly improving air conditioning comfort.

[0049] According to an embodiment of the present invention, a method for controlling an air conditioner is provided. Figure 1 The flowchart of one embodiment of the method of the present invention is shown. The control method of the air conditioner is applied to the air supply control of an air conditioner with upper and lower separate air guides, the air conditioner has an air inlet and an air outlet, the air outlet has two or more air guide components, the two or more air guide components of the air outlet can operate in different air supply modes, and the compressor of the air conditioner can operate at different frequencies; m temperature detection devices are correspondingly provided at the m air inlet angles at the upper part of the air inlet, n temperature detection devices are correspondingly provided at the n air inlet angles at the lower part of the air inlet, and p temperature detection devices are correspondingly provided at the p air inlet angles in the middle part of the air inlet, m, n, and p are all positive integers, preferably m=5, n=5, and p=3. Among them, for the p temperature detection devices, P can be considered to be 3; but with the addition of a temperature detection device distributed horizontally at the upper part and a temperature detection device distributed horizontally at the lower part, p can actually be considered to be 5. In the scheme of the present invention, Figure 1 As shown, the air conditioner control method includes: steps S110 to S140.

[0050] At step S110, the temperature detected by each of the m temperature detection devices is obtained to obtain m upper air inlet temperatures; the temperature detected by each of the n temperature detection devices is obtained to obtain n lower air inlet temperatures; the temperature detected by each of the p temperature detection devices is obtained to obtain p middle air inlet temperatures; and the set temperature under the current operating mode of the air conditioner is obtained; wherein the current operating mode of the air conditioner includes: the cooling mode of the air conditioner or the heating mode of the air conditioner.

[0051] In step S120, the average value of the m upper air inlet temperatures is determined and recorded as the upper average air inlet temperature, such as Figure 12 The current temperature of the upper part of the indoor unit air inlet is shown. Figure 13 The upper air inlet temperature shown in FIG. 1 is shown; the average value of the n lower air inlet temperatures is determined and recorded as the lower average air inlet temperature, such as Figure 12 The current temperature at the lower part of the indoor unit air inlet is shown. Figure 13 and determine the average of the p middle air inlet temperatures, recorded as the middle average air inlet temperature, such as Figure 12 The current temperature in the middle of the indoor unit air inlet is shown. Figure 13 The middle temperature of the air inlet is shown.

[0052] At step S130, when the air conditioner is turned on and the current operating mode of the air conditioner is run, the air supply mode of the two or more air guide components of the air outlet is controlled, the frequency of the compressor of the air conditioner is controlled, and based on the set temperature in the current operating mode of the air conditioner, combined with at least one of the upper average air inlet temperature and the lower average air inlet temperature, the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner are adjusted.

[0053] At step S140, when the air conditioner is operated in the air supply mode of the two or more air guide components of the air outlet, at least one of the operating speed and residence time of the two or more air guide components of the air outlet at the corresponding positions is adjusted in combination with at least one of the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and the middle average air inlet temperature.

[0054] The solution of the present invention proposes an automatic air supply control scheme for air conditioners with upper and lower separate air guides. The automatic air supply scheme is used to adjust the air supply mode of the air conditioner according to the comparison between the ambient temperature and the set temperature of the upper and lower parts of the room, and the difference between the inlet temperature and the average temperature at different air inlet angles. This can not only achieve rapid temperature rise and fall, but also maintain high-precision temperature control and reduce the discomfort caused by the wind, thereby greatly improving the comfort of air conditioning.

[0055] In some embodiments, the two or more air guide assemblies of the air outlet include: an upper left and right air guide assembly located at the upper portion of the air outlet, a lower left and right air guide assembly located at the lower portion of the air outlet, and an upper and lower air guide assembly located between the upper and lower portions of the air outlet. The air supply modes of the two or more air guide assemblies of the air outlet include: at least one of: a first mode in the current operating mode of the air conditioner, a second mode in the current operating mode of the air conditioner, and a third mode in the current operating mode of the air conditioner.

[0056] Among them, the first mode in the current operating mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components operate alternately, and the upper and lower air guide components operate independently; for example: mode A in cooling mode, or mode D in heating mode.

[0057] The second mode under the current operating mode of the air conditioner is: the upper left and right air guide components are running, the lower left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode B in cooling mode, or mode E in heating mode.

[0058] The third mode under the current operating mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components both stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode C in cooling mode, or mode F in heating mode.

[0059] Figure 9 It is a structural schematic diagram of the air guide structure with upper and lower parts for air guide. Figure 9 It includes two upper and lower left and right wind guide components (such as the upper left and right wind sweeping component 3 and the lower left and right wind sweeping component 4), a driving component (such as the driving component 2) and an air outlet frame (such as the air outlet frame 1). The left and right wind guide components and the driving component are connected to the air outlet frame. The driving component can simultaneously control the upper and lower left and right wind guide components, so that the upper and lower left and right wind guide components can run alternately or independently. Figure 9 In the example shown, the left and right air guide blades are divided into two parts, upper and lower.

[0060] exist Figure 11 In the control scheme under the cooling operation mode shown, there are three air-conditioning air guide components, namely the upper left and right air guide components, the lower left and right air guide components and the upper and lower air guide components. The three air supply methods are described as follows: A mode air supply, B mode air supply, and C mode air supply.

[0061] exist Figure 12In the control scheme under the heating operation mode shown, the three air supply modes are described as follows: D mode air supply, E mode air supply, and F mode air supply.

[0062] In the solution of the present invention, asynchronous air guidance: the upper and lower left and right air guidance components move asynchronously and staggeredly, increasing indoor air disturbance and promoting temperature exchange. Single-sided air guidance: only one of the upper and lower left and right air guidance components is in operation, and the other left and right air guidance component is closed or fixed in a certain position, so that only the upper or lower part of the air conditioner is in left and right air guidance operation. The automatic air supply control solution of the upper and lower separated air guidance air conditioner is adopted. According to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, the air supply mode of the air conditioner is adjusted, which can achieve rapid temperature rise and fall, perform high-precision temperature control, reduce the discomfort caused by the wind feeling, improve the comfort of the air conditioner, and solve the problems of complex air supply mode adjustment and wind discomfort of the upper and lower separated air guidance air conditioner.

[0063] In some embodiments, the m temperature detection devices are uniformly arranged circumferentially in the air inlet area at the upper part of the air inlet along the air inlet direction of the upper part of the air inlet; the n temperature detection devices are uniformly arranged circumferentially in the air inlet area at the lower part of the air inlet along the air inlet direction of the lower part of the air inlet; and the p temperature detection devices are vertically distributed in the air inlet area at the middle part of the air inlet along the middle part of the air inlet.

[0064] Figure 10 This is a schematic diagram of the distribution of the air conditioner temperature detectors of the present invention, wherein (a) is a schematic diagram of the horizontal circumferential distribution of the temperature detection devices along the air inlet, and (b) is a schematic diagram of the vertical distribution of the temperature detection devices along the middle of the air inlet. In (a), there are five horizontally distributed temperature detection devices in the upper part and five horizontally distributed temperature detection devices in the lower part. Figure 10 As shown, the air conditioner has an indoor heat exchanger 6, an indoor fan 7, upper and lower air guide components 8, left and right air guide components 9, and an indoor air inlet area 10. Five temperature detectors (such as temperature sensor 5) are evenly distributed along the air inlet area on the upper and lower parts of the air conditioner, and five temperature detectors are also evenly distributed along the vertical direction in the middle of the air inlet (of which the top and bottom two temperature detectors are shared with the upper and lower temperature detectors of the air conditioner). There are a total of thirteen temperature detectors. The average temperature detected by the five temperature detection devices on the top represents the upper temperature of the indoor air inlet, the average temperature detected by the five temperature detection devices on the bottom represents the lower temperature of the indoor air inlet, and the average temperature detected by the five temperature detection devices in the vertical direction in the middle of the air inlet represents the middle temperature of the air inlet. Figure 10 In the example shown, the operation of different air guide plates can be adjusted according to different temperature differences through multiple air inlet temperature detection devices.

[0065] In the solution of the present invention, a total of thirteen temperature detection devices are arranged at the air inlet of the air conditioner, namely five temperature detection devices distributed along the horizontal circumference of the air inlet at the upper part of the air inlet, five temperature detection devices distributed along the horizontal circumference of the air inlet at the lower part of the air inlet, and five temperature detection devices distributed along the vertical direction of the air inlet in the middle of the air inlet. Two of them are repeated, so there are a total of thirteen temperature detection devices. The three groups of temperature detection devices are all evenly placed. In the solution of the present invention, the air inlet angle is just a rough statement. The essence is that different temperature detection devices are used for different air guide plates with different wind sweeping ranges and wind sweeping angles. Among them, the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the upper part of the air inlet correspond to the upper left and right air guide plates; the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the lower part of the air inlet correspond to the lower left and right air guide plates, and the five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet correspond to the upper and lower air guide plates.

[0066] In the solution of the present invention, there are three average temperatures, namely the upper air inlet temperature representing the upper indoor temperature, the lower air inlet temperature representing the lower indoor temperature, and the middle air inlet temperature representing the air inlet temperature. Set temperature: the target temperature set by the air conditioner. Upper air inlet temperature: the indoor ambient temperature above the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the upper part of the air inlet. Lower air inlet temperature: the indoor ambient temperature below the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the lower part of the air inlet. Middle air inlet temperature: represented by the average value of the five temperature detection devices located in the middle of the air inlet and distributed in the vertical direction.

[0067] The air conditioner corresponding to the solution of the present invention is a variable-frequency air conditioner with upper and lower air guides. The air outlet has two upper and lower left and right air guide assemblies, and a top and bottom air guide assembly connecting the upper and lower air outlets. The indoor unit of the air conditioner has more than ten temperature detection devices, located at the upper and lower parts of the air inlet, for detecting the upper and lower ambient temperatures of the room. The average temperature detected by the five upper temperature detection devices represents the upper temperature of the indoor unit's air inlet, while the average temperature detected by the five lower temperature detection devices represents the lower temperature of the indoor unit's air inlet. The air conditioner can be a cabinet unit, or other type of wall-mounted unit or window unit with upper and lower air guides. The five temperature detection devices are evenly distributed along the horizontal circumference of the air inlet. Five temperature detection devices are required because, on the one hand, they can accurately identify the temperature at different angles on the left and right sides of the room, and on the other hand, they can save costs. If there are too few temperature detection devices, such as two or three, they cannot detect temperature differences at multiple angles, making it impossible to achieve targeted temperature control at multiple angles. On the other hand, if there are too many temperature detection devices, it would be wasteful and increase costs. On the other hand, the indoor temperature differences are relatively rough, not with noticeable temperature differences every few degrees, so too many temperature detection devices are not necessary. Therefore, setting five temperature detection devices is a more appropriate number of temperature detection devices.

[0068] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner, combined with at least one of the upper average air inlet temperature and the lower average air inlet temperature, including: a first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0069] The following combination Figure 2 The flowchart of an embodiment of the first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, which further illustrates the specific process of the first process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130, including: steps S210 to S240.

[0070] Step S210, controlling the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and controlling the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner.

[0071] Step S220, for the first time, determines whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold; wherein, the set first frequency is such as the frequency A1 in the cooling mode or the frequency D1 in the heating mode, and the set first temperature threshold is the set threshold T1.

[0072] Step S230: If it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner.

[0073] Step S240: If it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, the air supply mode of the two or more air guide components of the air outlet is controlled to be the second mode in the current operating mode of the air conditioner, and the frequency of the compressor is controlled to be the second frequency set in the current operating mode of the air conditioner; wherein the set second frequency is less than the set first frequency, such as the frequency B1 in the cooling mode or the frequency E1 in the heating mode.

[0074] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the first process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0075] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner, combined with at least one of the upper average air inlet temperature and the lower average air inlet temperature, and also includes: a second process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0076] The following combination Figure 3 The flowchart of an embodiment of the second process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, which further illustrates the specific process of the second process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130, including: steps S310 to S340.

[0077] Step S310, when it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, after controlling the air supply mode of the two or more air guide components of the air outlet to be the second mode in the current operating mode of the air conditioner, and controlling the frequency of the compressor to be the second frequency set in the current operating mode of the air conditioner, it is determined for the first time whether the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold.

[0078] Step S320: If it is determined for the first time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set second temperature threshold, then it is determined for the second time whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold.

[0079] Step S330: If it is determined for the second time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner.

[0080] Step S340: If it is determined for the second time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the second mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the second frequency set in the current operating mode of the air conditioner.

[0081] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the second process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0082] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner, combined with at least one of the upper average air inlet temperature and the lower average air inlet temperature, and also includes: a third process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0083] The following combination Figure 4 The flowchart of an embodiment of the third process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, which further illustrates the specific process of the third process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130, including: step S410 to step S450.

[0084] Step S410: If it is determined for the first time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold, the air supply mode of the two or more air guide components of the air outlet is controlled to be the third mode in the current operating mode of the air conditioner, and the frequency of the compressor is controlled to be the third frequency set in the current operating mode of the air conditioner; wherein the set third frequency is less than the set second frequency, such as the frequency C1 in the cooling mode or the frequency F1 in the heating mode.

[0085] Step S420, first determine whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set third temperature threshold; wherein the set third temperature threshold is such as the set threshold T3.

[0086] Step S430, if it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set third temperature threshold, then it is determined for the second time whether the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold; wherein, the set first temperature threshold is greater than the set second temperature threshold, the set second temperature threshold is greater than the set third temperature threshold, and the set second temperature threshold is such as the set threshold T2.

[0087] Step S440: If it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set second temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the third mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the third frequency set in the current operating mode of the air conditioner.

[0088] Step S450: If it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set second temperature threshold, then return to re-determine for the second time whether the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold.

[0089] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the third process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0090] In some embodiments, step S130 adjusts the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner, combined with at least one of the upper average air inlet temperature and the lower average air inlet temperature, and also includes: a fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor.

[0091] The following combination Figure 5 The flowchart of an embodiment of the fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in the method of the present invention is shown, which further illustrates the specific process of the fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor in step S130, including: steps S510 to S540.

[0092] Step S510: If it is determined for the first time that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set third temperature threshold, the air supply mode of the two or more air guide components of the air outlet is controlled to be the third mode in the current operating mode of the air conditioner, and the frequency of the compressor is controlled to 0.

[0093] Step S520 , determining for the second time whether the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operation mode of the air conditioner is less than or equal to a set first temperature threshold.

[0094] Step S530: If it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the third mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to 0.

[0095] Step S540: If it is determined for the second time that the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than the set first temperature threshold, then return to continue controlling the air supply mode of the two or more air guide components of the air outlet to be the third mode in the current operating mode of the air conditioner, and continue to control the frequency of the compressor to be the third frequency set in the current operating mode of the air conditioner.

[0096] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the fourth process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy-saving effects.

[0097] Figure 11 The figure is a flow chart of the automatic air supply control process of the present invention. Figure 11 As shown in the figure, the automatic cooling air supply control process includes:

[0098] Step a: When the refrigeration is turned on, the upper and lower parts of the inverter cabinet are opened to supply air in mode A, and the maximum operating frequency of the compressor is limited to A1; and during the process, it is determined whether the difference between the current temperature at the lower part of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold T1: if so, proceed to step b; otherwise, the inverter cabinet air conditioner still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0099] In the solution of the present invention, the air conditioner is turned on for cooling. At this time, the indoor temperature is relatively high. The air conditioner supplies air in mode A, and the upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates are all opened. This can increase the indoor air disturbance and quickly cool the room. Because air expands when heated and contracts when cooled, the temperature in the lower part of the room is lower than the temperature in the upper part of the room. Therefore, when cooling, it is necessary to first determine whether the temperature in the lower part of the room is close to the set temperature. If so, proceed to the next step. If not, continue with the current operation.

[0100] Step b: The air conditioner now supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1; and continue to determine whether the difference between the current upper temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T2: if so, proceed to step c; otherwise, continue to determine whether the difference between the current lower temperature of the indoor unit air inlet 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, proceed to step a.

[0101] In the solution of the present invention, at this time, the lower indoor temperature is close to the set temperature, the air conditioner supplies air in mode B, the upper and lower air guide components are fixed at the upward air guide position, the lower left and right air guide components stop running and are in the minimum air outlet position, and the upper left and right air guide plates operate normally. Because the lower indoor temperature is close to the set temperature at this time, the upper and lower air guide plates must be fixed at the upward air outlet position to prevent the cold air from continuing to blow downward, causing the lower indoor temperature to be lower than the set temperature and continue to decrease. Similarly, the lower left and right air guide components stop running and are in the minimum air outlet position to prevent the lower indoor temperature from being too low. Because thermal expansion and contraction cause hot air to float up and cold air to sink, the temperature in the upper part of the room is higher than that in the lower part. Therefore, although the lower temperature of the room is close to the set temperature at this time, the upper temperature is still higher than the set temperature. Therefore, the upper left and right air guide plates operate normally, and during operation, it is judged whether the upper temperature of the room is close to the set temperature. If so, proceed to the next step. Otherwise, it depends on whether the indoor cooling capacity is insufficient due to changes in the air supply mode and the maximum frequency of the compressor. Therefore, it is necessary to continue to judge whether the lower temperature of the room is still close to the set temperature. If so, continue to operate in this way. Otherwise, it means that the cooling capacity is insufficient, and return to step a.

[0102] Step c, the air conditioner now supplies air in mode C, and the maximum operating frequency of the compressor is limited to C1; and continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T3: if so, proceed to step d; otherwise, continue to determine whether the difference between the current upper temperature of the indoor unit air inlet 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 temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T1, if so, proceed to step b, otherwise, proceed to step a; at this time, the upper and lower parts of the room are close to the set temperature, the air conditioner supplies air in mode C, the two left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed at the upward air guide position.

[0103] In the solution of the present invention, only the upper portion of the air conditioner blows out a weak cool air to maintain a stable room temperature. At this time, it is necessary to determine whether the lower room temperature is less than a set temperature within a certain range. If so, the process proceeds to the next step. Due to changes in the air supply mode and the maximum frequency of the compressor, the indoor temperature may not only decrease but also decrease. Otherwise, the process determines whether the upper room temperature is less than the set temperature. If so, the process continues to operate in the current mode. Otherwise, the process continues to determine whether the lower room temperature is less than a set temperature within a certain range. If so, the process proceeds to step b, otherwise, the process proceeds to step a. Each time the air supply mode is switched, it is necessary to determine whether the current temperature is less than a certain value and greater than another value. Based on this determination, the process then determines whether to continue the current operation, proceed to the next stage, or return to another stage.

[0104] Step d: The air conditioner now supplies air in mode C, and the compressor stops; and continues to determine whether the difference between the current upper temperature of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold value T1: If so, the air conditioner now supplies air in mode C, and the compressor stops; otherwise, enter step c; at this time, the lower indoor ambient temperature is lower than the set value within a certain range, and air is supplied in mode C, the compressor stops, and continues to determine whether the upper indoor temperature is lower than the set temperature within a certain range. If so, continue to operate in this manner, otherwise return to c.

[0105] In the solution of the present invention, the upper and lower part-guided variable frequency air conditioner can automatically control the movement of the upper and lower air guide components according to the difference between the upper and lower indoor temperatures and the set temperature under the above-mentioned air supply control method. While increasing the temperature rise and temperature drop rates, it can also reduce indoor temperature fluctuations, improve temperature control accuracy, and improve the problem of blowing discomfort.

[0106] Figure 12 This is a flow chart of the automatic air supply control process for heating of the present invention. The heating process is similar to the cooling process, except that the temperature is different. Figure 12 As shown in the figure, the automatic air supply control process for heating includes:

[0107] Step e: When the heating mode is on, the upper and lower parts of the inverter cabinet air-conditioning system are opened to supply air in mode D, and the maximum operating frequency of the compressor is limited to D1; and during the process, it is determined whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T1: if so, proceed to step f; otherwise, the inverter cabinet air-conditioning system still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0108] Step f, the air conditioner now supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1; and continue to determine whether the difference between the set temperature and the current temperature at the lower part of the indoor unit's air inlet is less than or equal to the set threshold value T2: if so, proceed to step g, otherwise, continue to determine whether the difference between the set temperature and the current temperature at the upper part of the indoor unit's air inlet is less than or equal to the set threshold value T1, if so, the air conditioner supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1, otherwise, proceed to step e.

[0109] Step g, the air conditioner now supplies air in mode F, and the maximum operating frequency of the compressor is limited to F1; and continue to determine whether the difference between the set temperature and the current upper temperature of the indoor unit air inlet is less than or equal to the set threshold value T3: if so, proceed to step h, otherwise, continue to determine whether the difference between the set temperature and the current lower temperature of the indoor unit air inlet is less than or equal to the set threshold value T2, if so, the air conditioner supplies air in mode F, and the maximum operating frequency of the compressor is limited to F1, otherwise, continue to determine whether the difference between the set temperature and the current upper temperature of the indoor unit air inlet is less than or equal to the set threshold value T1, if so, proceed to step f, otherwise, proceed to step e.

[0110] Step h: The air conditioner now supplies air in mode F, and the compressor stops; and continues to determine whether the difference between the set temperature and the current temperature at the lower part of the indoor unit's air inlet is less than or equal to the set threshold value T1: If so, the air conditioner now supplies air in mode D, and the compressor stops; otherwise, enter step g.

[0111] The present invention proposes an automatic air supply control scheme for variable-frequency air conditioners with upper and lower split air guides. This solution addresses the problems of condensation and airflow discomfort caused by adjusting only the wind speed in related solutions. It improves temperature control accuracy while maintaining air conditioning effectiveness, thereby enhancing comfort. In the present invention, multiple temperature intervals are divided based on the difference between the upper and lower ambient temperatures and the set temperature. Each temperature interval corresponds to a specific operating mode of the upper and lower air guides. By limiting the maximum operating frequency of the compressor in different intervals, the greater the temperature difference, the higher the compressor operating frequency, and the smaller the temperature difference, the lower the compressor operating frequency, thereby ensuring air conditioning energy efficiency while reducing the risk of condensation.

[0112] In some embodiments, the upper left and right wind guide components include: upper left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and stay time of the upper left and right wind guide plates at the stay angles or stay positions can be adjusted; the lower left and right wind guide components include: lower left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and stay time of the lower left and right wind guide plates at the stay angles or stay positions can be adjusted; the upper and lower wind guide components include: upper and lower wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and stay time of the upper and lower wind guide plates at the stay angles or stay positions can be adjusted. Among them, the air guide component (i.e., the air guide assembly) includes several air guide plates, each of which has its own axis, and the air guide plates can rotate along the axis, which is called the swing of the air guide blades in the control of the air conditioner. The solution of the present invention is mainly aimed at the movement form of the swing of the air guide blades; in addition, there is a kind of situation in which the air guide plates of the entire moving part of the air guide component are fixed together and move left and right along the same axis. This situation can also be applied to the solution of the present invention.

[0113] In the solution of the present invention, the left and right air outlet ranges corresponding to the upper and lower temperature detection devices are defined as the left and right air guide plate sweeping ranges divided into five equal parts, corresponding one-to-one to the temperature detection devices from left to right. The upper left and right air guide plates correspond to the upper temperature detection devices, and the lower left and right air guide plates correspond to the lower temperature detection devices. The air outlet angles corresponding to the three middle temperature detection devices in the upper and lower parts are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices. The air outlet angles corresponding to the leftmost and rightmost temperature detection devices are the angles corresponding to the leftmost and rightmost sides of the corresponding air guide plate movement range. The air outlet range of the middle vertical temperature detection device is the upper and lower air guide plate sweeping range divided into five equal parts, corresponding one-to-one to the temperature detection devices from top to bottom. The air outlet angles corresponding to the three middle temperature detection devices in the vertical direction are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices. The air outlet angles corresponding to the uppermost and rightmost temperature detection devices are the angles corresponding to the uppermost and lowermost sides of the corresponding upper and lower air guide plate movement ranges. This section describes the definitions of the air outlet range and air outlet angles.

[0114] In the solution of the present invention, the temperature detection device is divided into three parts: five temperature detection devices located at the upper part of the air inlet and evenly distributed along the horizontal circumference of the air inlet; five temperature detection devices located at the lower part of the air inlet and evenly distributed along the horizontal circumference of the air inlet; and five temperature detection devices located in the middle of the air inlet and evenly distributed along the vertical direction. Because the top and bottom two temperature detection devices of the vertically distributed temperature detection devices are shared with the temperature detection devices in the upper horizontal distribution and the middle of the lower horizontal distribution, there are a total of thirteen temperature detection devices. Among them, the five temperature detection devices located at the upper part of the air inlet and evenly distributed along the horizontal circumference of the air inlet correspond to the upper left and right air guide plates; the five temperature detection devices located at the lower part of the air inlet and evenly distributed along the horizontal circumference of the air inlet correspond to the lower left and right air guide plates; and the five temperature detection devices located in the middle of the air inlet and evenly distributed along the vertical direction correspond to the upper and lower air guide plates.

[0115] Among them, in step S140, when the air conditioner is operated according to the air supply mode of the two or more air guide components of the air outlet, combined with the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and at least one of the middle average air inlet temperature, at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions is adjusted, including: when the air supply mode of the two or more air guide components of the air outlet is the first mode, at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions is adjusted in the first mode.

[0116] The following combination Figure 6The method of the present invention is shown as a flow chart of an embodiment of the process of adjusting at least one of the operating speeds and residence times of two or more air guide components of the air outlet at corresponding positions in a first manner, further illustrating the specific process of adjusting at least one of the operating speeds and residence times of two or more air guide components of the air outlet at corresponding positions in a first manner in step S140, including: steps S610 to S660.

[0117] Step S610, when the air supply mode of more than two air guide components of the air outlet is the first mode, determine the absolute value of the difference between each upper air inlet temperature among the m upper air inlet temperatures and the upper average air inlet temperature, and record it as the absolute value of the temperature difference at the first air inlet angle; determine the absolute value of the difference between each lower air inlet temperature among the n lower air inlet temperatures and the lower average air inlet temperature, and record it as the absolute value of the temperature difference at the second air inlet angle; and determine the absolute value of the difference between each middle air inlet temperature among the p middle air inlet temperatures and the middle average air inlet temperature, and record it as the absolute value of the temperature difference at the third air inlet angle.

[0118] Step S620, for each of the absolute values ​​of the temperature difference of the first air inlet angle, the absolute value of the temperature difference of the second air inlet angle, and the absolute value of the temperature difference of the third air inlet angle, determine the temperature interval to which the absolute value of the temperature difference of each air inlet angle belongs within the set temperature range; wherein the temperature interval includes: a first interval, a second interval, a third interval, and a fourth interval in which the temperature values ​​increase in sequence; the upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates corresponding to each air inlet angle are connected; The wind guide plate corresponding to the absolute value of the temperature difference is recorded as the corresponding wind guide plate; and the temperature detection device corresponding to the absolute value of the temperature difference of each air inlet angle among the m temperature detection devices, the n temperature detection devices, and the p temperature detection devices is recorded as the corresponding temperature detection device; wherein, taking the absolute value of the temperature difference of the first air inlet angle as an example, the first interval is the interval of α1≤t1, the second interval is the interval of t1<α1≤t2, the third interval is the interval of t3≤α1<t4, and the fourth interval is the interval of t4≤α1.

[0119] Step S630: If the absolute value of the temperature difference of each air inlet angle is in the first range, the corresponding air guide plate is controlled to increase its operating speed by a set first coefficient when it moves to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device; wherein the set first coefficient is, for example, 1 times.

[0120] Step S640, if the absolute value of the temperature difference of each air inlet angle is in the second range, the corresponding air guide plate is controlled to increase its operating speed by a set second coefficient when it moves to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second coefficient is smaller than the set first coefficient, and the set first coefficient is such as 1 times.

[0121] Step S650: If the absolute value of the temperature difference of each air inlet angle is in the third interval, the corresponding air guide plate is controlled to stay for a set first stay time when it moves to the air outlet range corresponding to the corresponding temperature detection device; wherein the set first stay time is such as 0.5s.

[0122] Step S660: If the absolute value of the temperature difference of each air inlet angle is in the fourth interval, the corresponding air guide plate is controlled to stay for a set second stay time when it moves to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second stay time is greater than the set first stay time, and the set second stay time is such as 1s.

[0123] Figure 13 This is a flow chart of the air supply process of mode A of the present invention. Figure 13 As shown, in Mode A, airflow is delivered in a staggered manner: the upper and lower left and right air guide assemblies operate independently, while the upper and lower air guide assemblies operate independently. During this process, the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the incoming air, the difference β1 between the temperature detected by the lower temperature detection device and the lower temperature of the incoming air, and the difference γ1 between the temperature detected by the middle vertical temperature detection device and the middle temperature of the incoming air are continuously determined. In Mode A, the upper and lower air guide assemblies are not affected by the left and right air guide assemblies. When the upper and lower air guide assemblies operate independently, the upper and lower air guide blades swing up and down, while when the left and right air guide assemblies operate, the air guide plates swing left and right.

[0124] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed of the upper left and right air guide plates is increased by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second. When α1≤t1 and the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the inlet air temperature at this position is lower than the upper average temperature. Therefore, when the air guide plates move to the air outlet range corresponding to the temperature detection device, they should move quickly to reduce the time the air guide plates stay in this range, thereby reducing the cooling output and reducing the indoor temperature difference.

[0125] If β1≤t1, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<β1≤t2, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤β1<t4, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤β1, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0126] If γ1≤t1, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<γ1≤t2, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤γ1<t4, when the upper and lower air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤γ1, when the upper and lower air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0127] In the solution of the present invention, this operating mode (i.e., mode A air supply) can increase the air disturbance in the room, improve the temperature uniformity in the room, increase the temperature drop rate, and quickly cool the room to approach the set temperature.

[0128] Figure 15 This is a flow chart of the D-mode air supply process of the present invention. Figure 15As shown, mode D air supply: The upper and lower left and right air guide assemblies operate alternately, while the upper and lower air guide assemblies operate independently. During this process, the difference α2 between the temperature detected by the upper temperature detection device and the upper temperature of the inlet air, the difference β2 between the temperature detected by the lower temperature detection device and the lower temperature of the inlet air, and the difference γ2 between the temperature detected by the middle vertical direction temperature detection device and the middle temperature of the inlet air are continuously determined. If α2 ≤ t1, the upper left and right air guides move to the outlet angle corresponding to the corresponding temperature detection device and stay for 1 second. If t1 < α2 ≤ t2, the upper left and right air guides move to the outlet angle corresponding to the corresponding temperature detection device and stay for 0.5 seconds. If t3 ≤ α2 < t4, the upper left and right air guides move to the outlet range corresponding to the corresponding temperature detection device at an increased speed of 0.5 times. If t4 ≤ α2, the upper left and right air guides move to the outlet range corresponding to the corresponding temperature detection device at an increased speed of 1 times. If β2≤t1, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second. If t1<β2≤t2, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds. If t3≤β2<t4, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times. If t4≤β2, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times. If γ2≤t1, the upper and lower air guide plates will stay for 1 second when they move to the air outlet angle corresponding to the corresponding temperature detection device. If t1<γ2≤t2, the upper and lower air guide plates will stay for 0.5 seconds when they move to the air outlet angle corresponding to the corresponding temperature detection device. If t3≤γ2<t4, the upper and lower air guide plates will increase the operating speed by 0.5 times when they move to the air outlet range corresponding to the corresponding temperature detection device. If t4≤γ1, the upper and lower air guide plates will increase the operating speed by 1 times when they move to the air outlet range corresponding to the corresponding temperature detection device.

[0129] In the solution of the present invention, this operating mode (D mode air supply) can increase the room air disturbance, improve the room temperature uniformity, increase the temperature rise rate, and make the room temperature rise quickly close to the set temperature.

[0130] In some embodiments, in step S140, when the air conditioner is operated according to the air supply mode of the two or more air guide components of the air outlet, at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions are adjusted in combination with the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and at least one of the middle average air inlet temperature. It also includes: when the air supply mode of the two or more air guide components of the air outlet is the second mode, at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions is adjusted in the second mode.

[0131] The following combination Figure 7 The method of the present invention is shown as a flow chart of an embodiment of the process of adjusting at least one of the operating speeds and residence times of two or more air guide components of the air outlet at corresponding positions in a second manner, further illustrating the specific process of adjusting at least one of the operating speeds and residence times of two or more air guide components of the air outlet at corresponding positions in a second manner in step S140, including: steps S710 to S760.

[0132] Step S710, when the air supply mode of more than two air guide components of the air outlet is the second mode, determine the absolute value of the difference between each upper air inlet temperature of the m upper air inlet temperatures and the upper average air inlet temperature, and record it as the absolute value of the temperature difference at the first air inlet angle.

[0133] Step S720, determine the temperature interval to which the absolute value of the temperature difference of the first air inlet angle belongs within the set temperature range; wherein, the temperature interval includes: a first interval, a second interval, a third interval and a fourth interval in which the temperature values ​​increase successively; and, the temperature detection device corresponding to the absolute value of the temperature difference of the first air inlet angle among the m temperature detection devices is recorded as a corresponding temperature detection device; wherein, taking the absolute value of the temperature difference of the first air inlet angle as an example, the first interval is the interval of α1≤t1, the second interval is the interval of t1<α1≤t2, the third interval is the interval of t3≤α1<t4, and the fourth interval is the interval of t4≤α1.

[0134] Step S730: If the absolute value of the temperature difference of the first air inlet angle is in the first range, the upper left and right air guide plates are controlled to increase their operating speed by a set first coefficient when they move to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device; wherein the set first coefficient is, for example, 1 times.

[0135] Step S740, if the absolute value of the temperature difference of the first air inlet angle is in the second range, the upper left and right air guide plates are controlled to increase their operating speed by a set second coefficient when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second coefficient is smaller than the set first coefficient, and the set first coefficient is such as 1 times.

[0136] Step S750: If the absolute value of the temperature difference of the first air inlet angle is in the third interval, the upper left and right air guide plates are controlled to stay for a set first stay time when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set first stay time is such as 0.5s.

[0137] Step S760: If the absolute value of the temperature difference of the first air inlet angle is in the fourth interval, the upper left and right air guide plates are controlled to stay for a set second stay time when they move to the air outlet range corresponding to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second stay time is greater than the set first stay time, and the set second stay time is such as 1s.

[0138] Figure 14 This is a flow chart of the air supply process of mode B of the present invention. Figure 14 As shown, air is supplied in mode B: the upper left and right air guide components are running, the lower left and right air guide components stop running and are in the minimum air outlet position, the upper and lower air guide components are fixed at the upward air guide position, and the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the inlet air is continuously judged during the process.

[0139] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0140] In the solution of the present invention, this operating mode (mode B air supply) can effectively reduce the wind sensation at the lower part of the air conditioner, improve the temperature uniformity of the room, and prevent excessive vertical temperature differences in the room.

[0141] Air supply in mode C: Both left and right air guide components stop running and are in the minimum air outlet position. The upper and lower air guide components are fixed in the upward air guide position. At this time, the temperature in the upper part of the room is close to the set temperature, and the temperature in 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 part of the air outlet to keep the room temperature stable.

[0142] According to experiments, the difference T1 can be 0°C to 2°C, preferably 1°C; the difference T2 can be -1°C to 1°C, preferably 0°C; the difference T3 can be -3°C to -1°C, preferably -2°C. The t1 can be -1°C to 0°C, preferably -0.5°C; the t2 can be -0.5°C to 0°C, preferably -0.2°C; the t3 can be 0°C to 0.5°C, preferably 0.2°C; and the t4 can be 0°C to 1°C, preferably 0.5°C.

[0143] In the solution of the present invention, this embodiment sets the maximum compressor operating frequency A1>B1>C1. Because the load of the air conditioner gradually decreases when cooling the room, the maximum compressor operating frequency can be reduced, thereby saving energy. In cooling mode, the overall air output will decrease when the air conditioner is in Mode B (the lower left and right air guide components are fixed at the minimum air outlet) and Mode C (the upper and lower left and right air sweep components are both fixed at the minimum air outlet). If the frequency is not changed, the outlet air temperature will decrease. When the outlet air temperature is lower than the indoor dew point, there is a risk of condensation. Therefore, in cooling mode, when the air conditioner is in Mode B and Mode C, it is also necessary to gradually reduce the maximum compressor operating frequency and increase the outlet air temperature to avoid condensation. The maximum operating frequency of compressors of different displacements is different, and the limit frequency of each stage is also different. The reference for conventional household compressors is as follows: A1: 60Hz-120Hz, B1: 40Hz-80Hz, C1: 15Hz-50Hz. The same compressor should ensure A1>B1>C1.

[0144] Figure 16 This is a flow chart of the E-mode air supply process of the present invention. Figure 16 As shown, mode E air supply: the lower left and right air guide components are in operation, the upper left and right air guide components are stopped and in the minimum air outlet position, the upper and lower air guide components are fixed in the downward air guide position, and the difference β2 between the temperature detected by the lower temperature detection device and the lower temperature of the inlet air is continuously determined during the process. If β2≤t1, the lower left and right air guide plates will stay for 1 second when they move to the air outlet angle corresponding to the corresponding temperature detection device. If t1<β2≤t2, the lower left and right air guide plates will stay for 0.5 seconds when they move to the air outlet angle corresponding to the corresponding temperature detection device. If t3≤β2<t4, the lower left and right air guide plates will increase their operating speed by 0.5 times when they move to the air outlet range corresponding to the corresponding temperature detection device. If t4≤β2, the lower left and right air guide plates will increase their operating speed by 1 time when they move to the air outlet range corresponding to the corresponding temperature detection device.

[0145] In the solution of the present invention, this operating mode (E-mode air supply) can effectively reduce the wind feeling on the upper part of the air conditioner, improve the temperature uniformity of the room, and prevent excessive vertical temperature differences in the room.

[0146] F mode air supply: Both left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed in the downward air guide position. At this time, the temperature in the lower part of the room is close to the set temperature, and the temperature in the upper part of the room is slightly higher than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak hot air from the lower part of the air outlet to keep the room temperature stable.

[0147] In the solution of the present invention, this embodiment sets the maximum operating frequency of the compressor to D1>E1>F1, mainly because the load in the air-conditioned heating room will gradually decrease, and the maximum operating frequency of the compressor can be reduced, thereby saving energy. The value ranges of the heating temperature differences T1, T2 and T3 are the same as those for cooling, and the value ranges of the temperatures t1, t2, t3 and t4 are the same as those for cooling. The air outlet range corresponding to the temperature detection device and the air outlet angle corresponding to the temperature detection device are consistent with those for cooling. Among them, the maximum operating frequency of compressors with different displacements is different, and the limit frequency of each stage is also different. The references for conventional household compressors are as follows: D1: 60Hz~120Hz, E1: 40Hz~80Hz, F1: 15Hz~50Hz. The same compressor should ensure D1>E1>F1.

[0148] In the solution of the present invention, an automatic air supply control solution is adopted for the air conditioner with upper and lower separate air guides. The air supply mode of the air conditioner is adjusted according to the comparison between the ambient temperature and the set temperature of the upper and lower parts of the room, and the difference between the inlet temperature and the average temperature at different air inlet angles. This can achieve rapid temperature rise and fall, maintain high-precision temperature control, reduce the discomfort caused by the wind, and greatly improve the comfort of the air conditioner.

[0149] The solution of the present invention provides high temperature control accuracy: based on the difference between the upper and lower room temperatures and the set temperature, multiple air supply modes are alternately controlled to achieve long-term temperature control with low temperature fluctuations. The solution of the present invention provides energy saving: different maximum compressor operating frequencies are set to correspond to different room temperature differences to achieve energy saving effects, and reduce the risk of condensation in cooling mode. The solution of the present invention provides wind comfort: based on the difference between the ambient temperature and the set temperature, the air supply mode is adjusted to improve the wind discomfort problem when the ambient temperature is close to the set temperature.

The air conditioner of claim 19, wherein the indoor unit of the air conditioner has an upper and a lower air guide assembly, a lower left and right air guide assembly, and an upper and a lower air guide assembly. The average value of the temperatures detected by m temperature detection devices is arranged at the upper part of the air inlet of the indoor unit of the air conditioner as the upper air inlet temperature, the average value of the temperatures detected by n temperature detection devices is arranged at the lower part of the air inlet as the lower air inlet temperature, and the average value of the temperatures detected by p temperature detection devices is arranged at the middle part of the air inlet as the middle air inlet temperature.

Under different air supply modes, the controller The operation mode of the upper left and right air guide assemblies, the lower left and right air guide assemblies, and the upper and lower air guide assemblies are controlled, and the position and operation speed of the upper left and right air guide plates are controlled according to the difference between the temperature detected by the temperature detection device at each air inlet angle at the upper part of the air inlet and the temperature at the upper part of the air inlet, the position and operation speed of the lower left and right air guide plates are controlled according to the difference between the temperature detected by the temperature detection device at each air inlet angle at the lower part of the air inlet and the temperature at the lower part of the air inlet, and the position and operation speed of the upper and lower air guide plates are controlled according to the difference between the temperature detected by the temperature detection device at each air inlet angle at the middle part of the air inlet and the temperature at the middle part of the air inlet, thereby realizing automatic adjustment of the air supply mode of the air conditioner; thus, by controlling the frequency of the compressor, the operation mode of the upper left and right air guide assemblies, the lower left and right air guide assemblies, and the upper and lower air guide assemblies according to the upper and lower temperatures of the air inlet, the temperatures at different angles of the air inlet and the set temperature, thereby realizing automatic adjustment of the air supply mode of the air conditioner, which is convenient for users to use and is conducive to improving the comfort of the air conditioner.

[0151] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. Figure 8 The structure diagram of an embodiment of the device of the present invention is shown. The control device of the air conditioner is applied to the air supply control of the air conditioner with upper and lower air guides, the air conditioner has an air inlet and an air outlet, the air outlet has two or more air guide components, the two or more air guide components of the air outlet can operate in different air supply modes, and the compressor of the air conditioner can operate at different frequencies; m temperature detection devices are correspondingly provided at the m air inlet angles at the upper part of the air inlet, n temperature detection devices are correspondingly provided at the n air inlet angles at the lower part of the air inlet, and p temperature detection devices are correspondingly provided at the p air inlet angles at the middle part of the air inlet, m, n, p are all positive integers, preferably m=5, n=5, p=3; in the scheme of the present invention, as Figure 8As shown, the air conditioner control device includes: an acquisition unit 102 and a control unit 104.

[0152] The acquisition unit 102 is configured to acquire the temperature detected by each of the m temperature detection devices to obtain m upper air inlet temperatures; acquire the temperature detected by each of the n temperature detection devices to obtain n lower air inlet temperatures; acquire the temperature detected by each of the p temperature detection devices to obtain p middle air inlet temperatures; and acquire the set temperature in the current operating mode of the air conditioner. The current operating mode of the air conditioner includes: the cooling mode of the air conditioner or the heating mode of the air conditioner. The specific functions and processing of the acquisition unit 102 are described in step S110.

[0153] The control unit 104 is configured to determine the average of the m upper air inlet temperatures, which is recorded as the upper average air inlet temperature. Figure 12 The current temperature of the upper part of the indoor unit air inlet is shown. Figure 13 The upper air inlet temperature shown in FIG. 1 is shown; the average value of the n lower air inlet temperatures is determined and recorded as the lower average air inlet temperature, such as Figure 12 The current temperature at the lower part of the indoor unit air inlet is shown. Figure 13 and determine the average of the p middle air inlet temperatures, recorded as the middle average air inlet temperature, such as Figure 12 The current temperature in the middle of the indoor unit air inlet is shown. Figure 13 The central temperature of the air inlet is shown, etc. The specific functions and processing of the control unit 104 are shown in step S120.

[0154] The control unit 104 is further configured to, when the air conditioner is turned on and the current operating mode of the air conditioner is being operated, control the air supply mode of the two or more air guide components of the air outlet, control the frequency of the air conditioner's compressor, and adjust the air supply mode of the two or more air guide components of the air outlet and the frequency of the air conditioner's compressor based on the set temperature in the current operating mode of the air conditioner and in combination with at least one of the upper average inlet air temperature and the lower average inlet air temperature. The specific functions and further processing of the control unit 104 are described in step S130.

[0155] The control unit 104 is further configured to adjust at least one of the operating speed and dwell time of the two or more air guide assemblies at corresponding positions of the air outlet, based on at least one of the m upper air inlet temperatures and the upper average air inlet temperature, the n lower air inlet temperatures and the lower average air inlet temperature, and the p middle air inlet temperatures and the middle average air inlet temperature, when the air conditioner is operating in the air supply mode of the two or more air guide assemblies at the air outlet. The specific functions and further processing of the control unit 104 are described in step S140.

[0156] The solution of the present invention proposes an automatic air supply control scheme for air conditioners with upper and lower separate air guides. The automatic air supply scheme is used to adjust the air supply mode of the air conditioner according to the comparison between the ambient temperature and the set temperature of the upper and lower parts of the room, and the difference between the inlet temperature and the average temperature at different air inlet angles. This can not only achieve rapid temperature rise and fall, but also maintain high-precision temperature control and reduce the discomfort caused by the wind, thereby greatly improving the comfort of air conditioning.

[0157] In some embodiments, the two or more air guide components of the air outlet include: an upper left and right air guide component located at the upper part of the air outlet, a lower left and right air guide component located at the lower part of the air outlet, and an upper and lower air guide component located between the upper and lower parts of the air outlet; the air supply mode of the two or more air guide components of the air outlet includes: at least one of: the first mode under the current operating mode of the air conditioner, the second mode under the current operating mode of the air conditioner, and the third mode under the current operating mode of the air conditioner.

[0158] Among them, the first mode in the current operating mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components operate alternately, and the upper and lower air guide components operate independently; for example: mode A in cooling mode, or mode D in heating mode.

[0159] The second mode under the current operating mode of the air conditioner is: the upper left and right air guide components are running, the lower left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode B in cooling mode, or mode E in heating mode.

[0160] The third mode under the current operating mode of the air conditioner is: the upper left and right air guide components and the lower left and right air guide components both stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed to guide air upward; for example: mode C in cooling mode, or mode F in heating mode.

[0161] Figure 9 It is a structural schematic diagram of the air guide structure with upper and lower parts for air guide. Figure 9It includes two upper and lower left and right wind guide components (such as the upper left and right wind sweeping component 3 and the lower left and right wind sweeping component 4), a driving component (such as the driving component 2) and an air outlet frame (such as the air outlet frame 1). The left and right wind guide components and the driving component are connected to the air outlet frame. The driving component can simultaneously control the upper and lower left and right wind guide components, so that the upper and lower left and right wind guide components can run alternately or independently. Figure 9 In the example shown, the left and right air guide blades are divided into two parts, upper and lower.

[0162] exist Figure 11 In the control scheme under the cooling operation mode shown, there are three air-conditioning air guide components, namely the upper left and right air guide components, the lower left and right air guide components and the upper and lower air guide components. The three air supply methods are described as follows: A mode air supply, B mode air supply, and C mode air supply.

[0163] exist Figure 12 In the control scheme under the heating operation mode shown, the three air supply modes are described as follows: D mode air supply, E mode air supply, and F mode air supply.

[0164] In the solution of the present invention, asynchronous air guidance: the upper and lower left and right air guidance components move asynchronously and staggeredly, increasing indoor air disturbance and promoting temperature exchange. Single-sided air guidance: only one of the upper and lower left and right air guidance components is in operation, and the other left and right air guidance component is closed or fixed in a certain position, so that only the upper or lower part of the air conditioner is in left and right air guidance operation. The automatic air supply control solution of the upper and lower separated air guidance air conditioner is adopted. According to the comparison between the ambient temperature of the upper and lower parts of the room and the set temperature, the air supply mode of the air conditioner is adjusted, which can achieve rapid temperature rise and fall, perform high-precision temperature control, reduce the discomfort caused by the wind feeling, improve the comfort of the air conditioner, and solve the problems of complex air supply mode adjustment and wind discomfort of the upper and lower separated air guidance air conditioner.

[0165] In some embodiments, the m temperature detection devices are uniformly arranged circumferentially in the air inlet area at the upper part of the air inlet along the air inlet direction of the upper part of the air inlet; the n temperature detection devices are uniformly arranged circumferentially in the air inlet area at the lower part of the air inlet along the air inlet direction of the lower part of the air inlet; and the p temperature detection devices are vertically distributed in the air inlet area at the middle part of the air inlet along the middle part of the air inlet.

[0166] Figure 10 The diagram of the distribution of the air conditioner temperature detectors of the present invention is shown in FIG. 1 , wherein (a) is a diagram of the horizontal circumferential distribution of the temperature detection devices along the air inlet, and (b) is a diagram of the vertical distribution of the temperature detection devices along the middle of the air inlet. Figure 10As shown, the air conditioner has an indoor heat exchanger 6, an indoor fan 7, upper and lower air guide components 8, left and right air guide components 9, and an indoor air inlet area 10. Five temperature detectors (such as temperature sensor 5) are evenly distributed along the air inlet area on the upper and lower parts of the air conditioner, and five temperature detectors are also evenly distributed along the vertical direction in the middle of the air inlet (of which the top and bottom two temperature detectors are shared with the upper and lower temperature detectors of the air conditioner). There are a total of thirteen temperature detectors. The average temperature detected by the five temperature detection devices on the top represents the upper temperature of the indoor air inlet, the average temperature detected by the five temperature detection devices on the bottom represents the lower temperature of the indoor air inlet, and the average temperature detected by the five temperature detection devices in the vertical direction in the middle of the air inlet represents the middle temperature of the air inlet. Figure 10 In the example shown, the operation of different air guide plates can be adjusted according to different temperature differences through multiple air inlet temperature detection devices.

[0167] In the solution of the present invention, a total of thirteen temperature detection devices are arranged at the air inlet of the air conditioner, namely five temperature detection devices distributed along the horizontal circumference of the air inlet at the upper part of the air inlet, five temperature detection devices distributed along the horizontal circumference of the air inlet at the lower part of the air inlet, and five temperature detection devices distributed along the vertical direction of the air inlet in the middle of the air inlet. Two of them are repeated, so there are a total of thirteen temperature detection devices. The three groups of temperature detection devices are all evenly placed. In the solution of the present invention, the air inlet angle is just a rough statement. The essence is that different temperature detection devices are used for different air guide plates with different wind sweeping ranges and wind sweeping angles. Among them, the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the upper part of the air inlet correspond to the upper left and right air guide plates; the five temperature detection devices evenly distributed along the horizontal circumference of the air inlet at the lower part of the air inlet correspond to the lower left and right air guide plates, and the five temperature detection devices evenly distributed along the vertical direction in the middle of the air inlet correspond to the upper and lower air guide plates.

[0168] In the solution of the present invention, there are three average temperatures, namely the upper air inlet temperature representing the upper indoor temperature, the lower air inlet temperature representing the lower indoor temperature, and the middle air inlet temperature representing the air inlet temperature. Set temperature: the target temperature set by the air conditioner. Upper air inlet temperature: the indoor ambient temperature above the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the upper part of the air inlet. Lower air inlet temperature: the indoor ambient temperature below the air inlet of the air conditioner indoor unit is represented by the average value of the five temperature detection devices located at the lower part of the air inlet. Middle air inlet temperature: represented by the average value of the five temperature detection devices located in the middle of the air inlet and distributed in the vertical direction.

[0169] The air conditioner corresponding to the solution of the present invention is a variable-frequency air conditioner with upper and lower air guides. The air outlet has two upper and lower left and right air guide assemblies, and a top and bottom air guide assembly connecting the upper and lower air outlets. The indoor unit of the air conditioner has more than ten temperature detection devices, located at the upper and lower parts of the air inlet, for detecting the upper and lower ambient temperatures of the room. The average temperature detected by the five upper temperature detection devices represents the upper temperature of the indoor unit's air inlet, while the average temperature detected by the five lower temperature detection devices represents the lower temperature of the indoor unit's air inlet. The air conditioner can be a cabinet unit, or other type of wall-mounted unit or window unit with upper and lower air guides. The five temperature detection devices are evenly distributed along the horizontal circumference of the air inlet. Five temperature detection devices are required because, on the one hand, they can accurately identify the temperature at different angles on the left and right sides of the room, and on the other hand, they can save costs. If there are too few temperature detection devices, such as two or three, they cannot detect temperature differences at multiple angles, making it impossible to achieve targeted temperature control at multiple angles. On the other hand, if there are too many temperature detection devices, it would be wasteful and increase costs. On the other hand, the indoor temperature differences are relatively rough, not with noticeable temperature differences every few degrees, so too many temperature detection devices are not necessary. Therefore, setting five temperature detection devices is a more appropriate number of temperature detection devices.

[0170] In some embodiments, the control unit 104 adjusts the air supply mode of the two or more air guide assemblies of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner and in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, including: a first process of adjusting the air supply mode of the two or more air guide assemblies of the air outlet and the frequency of the compressor, specifically as follows:

[0171] The control unit 104 is further configured to control the air supply mode of the two or more air guide components of the air outlet to be the first mode in the current operating mode of the air conditioner, and to control the frequency of the compressor to be the first frequency set in the current operating mode of the air conditioner. The specific functions and further processing of the control unit 104 are shown in step S210.

[0172] The control unit 104 is further configured to first determine whether the absolute value of the difference between the lower average inlet air temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to a first set temperature threshold; wherein the set first frequency is, for example, frequency A1 in cooling mode or frequency D1 in heating mode, and the set first temperature threshold is set threshold T1. The specific functions and further processing of the control unit 104 are described in step S220.

[0173] The control unit 104 is further configured to, if it is first determined that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is greater than a set first temperature threshold, return to continue controlling the air supply mode of the two or more air guide components of the air outlet to the first mode in the current operating mode of the air conditioner, and continue controlling the frequency of the compressor to the first frequency set in the current operating mode of the air conditioner. The specific functions and further processing of the control unit 104 are shown in step S230.

[0174] The control unit 104 is further configured to, if it is first determined that the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is less than or equal to a set first temperature threshold, control the air supply mode of the two or more air guide components of the air outlet to be the second mode in the current operating mode of the air conditioner, and control the frequency of the compressor to be the second frequency set in the current operating mode of the air conditioner; wherein the set second frequency is less than the set first frequency, such as frequency B1 in cooling mode or frequency E1 in heating mode. The specific functions and further processing of the control unit 104 are described in step S240.

The specific functions and further processing of the control unit 104 are shown in step S340.

[0181] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the second process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0182] In some embodiments, the control unit 104 adjusts the air supply mode of the two or more air guide assemblies of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, further comprising: a third process of adjusting the air supply mode of the two or more air guide assemblies of the air outlet and the frequency of the compressor, specifically as follows:

[0188] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the third process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; setting different maximum operating frequencies of the compressor to correspond to different room temperature differences can achieve energy-saving effects.

[0189] In some embodiments, the control unit 104 is further configured to adjust the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor of the air conditioner based on the set temperature in the current operating mode of the air conditioner in combination with at least one of the upper average air inlet temperature and the lower average air inlet temperature, and further includes: a fourth process of adjusting the air supply mode of the two or more air guide components of the air outlet and the frequency of the compressor, specifically as follows:

[0190] The control unit 104 is further configured to control the air supply mode of the two or more air guide components of the air outlet to the third mode in the current operating mode of the air conditioner, and control the frequency of the compressor to 0, if the absolute value of the difference between the lower average air inlet temperature and the set temperature in the current operating mode of the air conditioner is determined for the first time to be less than or equal to a set third temperature threshold.

[0193] The control unit 104 is further configured to, if the absolute value of the difference between the upper average air inlet temperature and the set temperature in the current operating mode of the air conditioner is determined for the second time to be greater than the set first temperature threshold, return to continue controlling the air supply mode of the two or more air guide components of the air outlet to the third mode in the current operating mode of the air conditioner, and continue controlling the frequency of the compressor to the third frequency set in the current operating mode of the air conditioner. The specific functions and further processing of the control unit 104 are shown in step S540.

[0194] In the solution of the present invention, by adjusting the air supply mode of more than two air guide components of the air outlet and the fourth process of the frequency of the compressor, a variety of 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 fluctuations. When the ambient temperature is close to the set temperature, the problem of wind discomfort can be improved; different maximum operating frequencies of the compressor are set to correspond to different room temperature differences to achieve energy-saving effects.

[0195] Figure 11 The figure is a flow chart of the automatic air supply control process of the present invention. Figure 11 As shown in the figure, the automatic cooling air supply control process includes:

[0196] Step a: When the refrigeration is turned on, the upper and lower parts of the inverter cabinet are opened to supply air in mode A, and the maximum operating frequency of the compressor is limited to A1; and during the process, it is determined whether the difference between the current temperature at the lower part of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold T1: if so, proceed to step b; otherwise, the inverter cabinet air conditioner still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0197] In the solution of the present invention, the air conditioner is turned on for cooling. At this time, the indoor temperature is relatively high. The air conditioner supplies air in mode A, and the upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates are all opened. This can increase the indoor air disturbance and quickly cool the room. Because air expands when heated and contracts when cooled, the temperature in the lower part of the room is lower than the temperature in the upper part of the room. Therefore, when cooling, it is necessary to first determine whether the temperature in the lower part of the room is close to the set temperature. If so, proceed to the next step. If not, continue with the current operation.

[0198] Step b: The air conditioner now supplies air in mode B, and the maximum operating frequency of the compressor is limited to B1; and continue to determine whether the difference between the current upper temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T2: if so, proceed to step c; otherwise, continue to determine whether the difference between the current lower temperature of the indoor unit air inlet 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, proceed to step a.

[0199] In the solution of the present invention, at this time, the lower indoor temperature is close to the set temperature, the air conditioner supplies air in mode B, the upper and lower air guide components are fixed at the upward air guide position, the lower left and right air guide components stop running and are in the minimum air outlet position, and the upper left and right air guide plates operate normally. Because the lower indoor temperature is close to the set temperature at this time, the upper and lower air guide plates must be fixed at the upward air outlet position to prevent the cold air from continuing to blow downward, causing the lower indoor temperature to be lower than the set temperature and continue to decrease. Similarly, the lower left and right air guide components stop running and are in the minimum air outlet position to prevent the lower indoor temperature from being too low. Because thermal expansion and contraction cause hot air to float up and cold air to sink, the temperature in the upper part of the room is higher than that in the lower part. Therefore, although the lower temperature of the room is close to the set temperature at this time, the upper temperature is still higher than the set temperature. Therefore, the upper left and right air guide plates operate normally, and during operation, it is judged whether the upper temperature of the room is close to the set temperature. If so, proceed to the next step. Otherwise, it depends on whether the indoor cooling capacity is insufficient due to changes in the air supply mode and the maximum frequency of the compressor. Therefore, it is necessary to continue to judge whether the lower temperature of the room is still close to the set temperature. If so, continue to operate in this way. Otherwise, it means that the cooling capacity is insufficient, and return to step a.

[0200] Step c, the air conditioner now supplies air in mode C, and the maximum operating frequency of the compressor is limited to C1; and continue to determine whether the difference between the current lower temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T3: if so, proceed to step d; otherwise, continue to determine whether the difference between the current upper temperature of the indoor unit air inlet 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 temperature of the indoor unit air inlet and the set temperature is less than or equal to the set threshold value T1, if so, proceed to step b, otherwise, proceed to step a; at this time, the upper and lower parts of the room are close to the set temperature, the air conditioner supplies air in mode C, the two left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed at the upward air guide position.

[0201] In the solution of the present invention, only the upper portion of the air conditioner blows out a weak cool air to maintain a stable room temperature. At this time, it is necessary to determine whether the lower room temperature is less than a set temperature within a certain range. If so, the process proceeds to the next step. Due to changes in the air supply mode and the maximum frequency of the compressor, the indoor temperature may not only decrease but also decrease. Otherwise, the process determines whether the upper room temperature is less than the set temperature. If so, the process continues to operate in the current mode. Otherwise, the process continues to determine whether the lower room temperature is less than a set temperature within a certain range. If so, the process proceeds to step b, otherwise, the process proceeds to step a. Each time the air supply mode is switched, it is necessary to determine whether the current temperature is less than a certain value and greater than another value. Based on this determination, the process then determines whether to continue the current operation, proceed to the next stage, or return to another stage.

[0202] Step d: The air conditioner now supplies air in mode C, and the compressor stops; and continues to determine whether the difference between the current upper temperature of the indoor unit's air inlet and the set temperature is less than or equal to the set threshold value T1: If so, the air conditioner now supplies air in mode C, and the compressor stops; otherwise, enter step c; at this time, the lower indoor ambient temperature is lower than the set value within a certain range, and air is supplied in mode C, the compressor stops, and continues to determine whether the upper indoor temperature is lower than the set temperature within a certain range. If so, continue to operate in this manner, otherwise return to c.

[0203] In the solution of the present invention, the upper and lower part-guided variable frequency air conditioner can automatically control the movement of the upper and lower air guide components according to the difference between the upper and lower indoor temperatures and the set temperature under the above-mentioned air supply control method. While increasing the temperature rise and temperature drop rates, it can also reduce indoor temperature fluctuations, improve temperature control accuracy, and improve the problem of blowing discomfort.

[0204] Figure 12 This is a flow chart of the automatic air supply control process for heating of the present invention. The heating process is similar to the cooling process, except that the temperature is different. Figure 12 As shown in the figure, the automatic air supply control process for heating includes:

[0205] Step e: When the heating mode is on, the upper and lower parts of the inverter cabinet air-conditioning system are opened to supply air in mode D, and the maximum operating frequency of the compressor is limited to D1; and during the process, it is determined whether the difference between the set temperature and the upper temperature of the current indoor unit air inlet is less than or equal to the set threshold value T1: if so, proceed to step f; otherwise, the inverter cabinet air-conditioning system still supplies air in mode A, and the maximum operating frequency of the compressor is limited to A1.

[0206] Step f, the air conditioner now supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1; and continue to determine whether the difference between the set temperature and the current temperature at the lower part of the indoor unit's air inlet is less than or equal to the set threshold value T2: if so, proceed to step g, otherwise, continue to determine whether the difference between the set temperature and the current temperature at the upper part of the indoor unit's air inlet is less than or equal to the set threshold value T1, if so, the air conditioner supplies air in mode E, and the maximum operating frequency of the compressor is limited to E1, otherwise, proceed to step e.

[0207] Step g, the air conditioner now supplies air in mode F, and the maximum operating frequency of the compressor is limited to F1; and continue to determine whether the difference between the set temperature and the current upper temperature of the indoor unit air inlet is less than or equal to the set threshold value T3: if so, proceed to step h, otherwise, continue to determine whether the difference between the set temperature and the current lower temperature of the indoor unit air inlet is less than or equal to the set threshold value T2, if so, the air conditioner supplies air in mode F, and the maximum operating frequency of the compressor is limited to F1, otherwise, continue to determine whether the difference between the set temperature and the current upper temperature of the indoor unit air inlet is less than or equal to the set threshold value T1, if so, proceed to step f, otherwise, proceed to step e.

[0208] Step h: The air conditioner now supplies air in mode F, and the compressor stops; and continues to determine whether the difference between the set temperature and the current temperature at the lower part of the indoor unit's air inlet is less than or equal to the set threshold value T1: If so, the air conditioner now supplies air in mode D, and the compressor stops; otherwise, enter step g.

[0209] The present invention proposes an automatic air supply control scheme for variable-frequency air conditioners with upper and lower split air guides. This solution addresses the problems of condensation and airflow discomfort caused by adjusting only the wind speed in related solutions. It improves temperature control accuracy while maintaining air conditioning effectiveness, thereby enhancing comfort. In the present invention, multiple temperature intervals are divided based on the difference between the upper and lower ambient temperatures and the set temperature. Each temperature interval corresponds to a specific operating mode of the upper and lower air guides. By limiting the maximum operating frequency of the compressor in different intervals, the greater the temperature difference, the higher the compressor operating frequency, and the smaller the temperature difference, the lower the compressor operating frequency, thereby ensuring air conditioning energy efficiency while reducing the risk of condensation.

[0210] In some embodiments, the upper left and right wind guide components include: upper left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and stay time of the upper left and right wind guide plates at the stay angles or stay positions can be adjusted; the lower left and right wind guide components include: lower left and right wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and stay time of the lower left and right wind guide plates at the stay angles or stay positions can be adjusted; the upper and lower wind guide components include: upper and lower wind guide plates, which can be rotated to change their angles or moved to change their positions and can stay at the rotated angles or moved positions, and the running speed and stay time of the upper and lower wind guide plates at the stay angles or stay positions can be adjusted.

[0211] In the solution of the present invention, the left and right air outlet ranges corresponding to the upper and lower temperature detection devices are defined as the left and right air guide plate sweeping ranges divided into five equal parts, corresponding one-to-one to the temperature detection devices from left to right. The upper left and right air guide plates correspond to the upper temperature detection devices, and the lower left and right air guide plates correspond to the lower temperature detection devices. The air outlet angles corresponding to the three middle temperature detection devices in the upper and lower parts are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices. The air outlet angles corresponding to the leftmost and rightmost temperature detection devices are the angles corresponding to the leftmost and rightmost sides of the corresponding air guide plate movement range. The air outlet range of the middle vertical temperature detection device is the upper and lower air guide plate sweeping range divided into five equal parts, corresponding one-to-one to the temperature detection devices from top to bottom. The air outlet angles corresponding to the three middle temperature detection devices in the vertical direction are the angles corresponding to the center position of the air outlet range corresponding to the temperature detection devices. The air outlet angles corresponding to the uppermost and rightmost temperature detection devices are the angles corresponding to the uppermost and lowermost sides of the corresponding upper and lower air guide plate movement ranges. This section describes the definitions of the air outlet range and air outlet angles.

[0212] In the solution of the present invention, the temperature detection device is divided into three parts: five temperature detection devices located at the upper part of the air inlet and evenly distributed along the horizontal circumference of the air inlet; five temperature detection devices located at the lower part of the air inlet and evenly distributed along the horizontal circumference of the air inlet; and five temperature detection devices located in the middle of the air inlet and evenly distributed along the vertical direction. Because the top and bottom two temperature detection devices of the vertically distributed temperature detection devices are shared with the temperature detection devices in the upper horizontal distribution and the middle of the lower horizontal distribution, there are a total of thirteen temperature detection devices. Among them, the five temperature detection devices located at the upper part of the air inlet and evenly distributed along the horizontal circumference of the air inlet correspond to the upper left and right air guide plates; the five temperature detection devices located at the lower part of the air inlet and evenly distributed along the horizontal circumference of the air inlet correspond to the lower left and right air guide plates; and the five temperature detection devices located in the middle of the air inlet and evenly distributed along the vertical direction correspond to the upper and lower air guide plates.

[0213] Among them, the control unit 104, when the air conditioner is operated in the air supply mode of the two or more air guide components of the air outlet, combines the m upper air inlet temperatures with the upper average air inlet temperature, the n lower air inlet temperatures with the lower average air inlet temperature, and the p middle air inlet temperatures with the middle average air inlet temperature, to adjust at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions, including: when the air supply mode of the two or more air guide components of the air outlet is the first mode, the process of adjusting at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at the corresponding positions in the first mode is specifically as follows:

[0214] The control unit 104 is further configured to, when the air supply mode of the two or more air guide assemblies of the air outlet is the first mode, determine the absolute value of the difference between each of the m upper air inlet temperatures and the upper average air inlet temperature, recording it as the absolute value of the temperature difference at the first air inlet angle; determine the absolute value of the difference between each of the n lower air inlet temperatures and the lower average air inlet temperature, recording it as the absolute value of the temperature difference at the second air inlet angle; and determine the absolute value of the difference between each of the p middle air inlet temperatures and the middle average air inlet temperature, recording it as the absolute value of the temperature difference at the third air inlet angle. The specific functions and further processing of the control unit 104 are shown in step S610.

[0215] The control unit 104 is further configured to determine the temperature interval to which the absolute value of the temperature difference of each air inlet angle belongs within the set temperature range, for the absolute value of the temperature difference of each air inlet angle, the absolute value of the temperature difference of the second air inlet angle, and the absolute value of the temperature difference of the third air inlet angle; wherein the temperature interval includes: a first interval, a second interval, a third interval, and a fourth interval with successively increasing temperature values; and the upper left and right air guide plates, the lower left and right air guide plates, and the upper and lower air guide plates corresponding to each of the temperature intervals. The air guide plate corresponding to the absolute value of the temperature difference at each air inlet angle is recorded as the corresponding air guide plate; and the temperature detection device corresponding to the absolute value of the temperature difference at each air inlet angle among the m temperature detection devices, the n temperature detection devices, and the p temperature detection devices is recorded as the corresponding temperature detection device; wherein, taking the absolute value of the temperature difference at the first air inlet angle as an example, the first interval is the interval of α1≤t1, the second interval is the interval of t1<α1≤t2, the third interval is the interval of t3≤α1<t4, and the fourth interval is the interval of t4≤α1. The specific functions and further processing of the control unit 104 are shown in step S620.

[0216] The control unit 104 is further configured to, if the absolute value of the temperature difference at each air inlet angle is within a first range, control the corresponding air guide plate to increase its operating speed by a predetermined first coefficient when it moves to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device; the predetermined first coefficient is, for example, 1. The specific functions and further processing of the control unit 104 are described in step S630.

[0217] The control unit 104 is further configured to, if the absolute value of the temperature difference at each air inlet angle is within the second range, control the corresponding air guide plate to increase its operating speed by a set second coefficient when moving to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second coefficient is less than the set first coefficient, such as 1. The specific functions and further processing of the control unit 104 are described in step S640.

[0218] The control unit 104 is further configured to, if the absolute value of the temperature difference at each air inlet angle is within a third interval, control the corresponding air guide plate to remain within the air outlet range corresponding to the corresponding temperature detection device for a predetermined first dwell time when the air guide plate moves to the air outlet range corresponding to the corresponding temperature detection device; the predetermined first dwell time is, for example, 0.5 seconds. The specific functions and further processing of the control unit 104 are described in step S650.

[0219] The control unit 104 is further configured to, if the absolute value of the temperature difference at each air inlet angle is within a fourth interval, control the corresponding air guide plate to remain within the air outlet range corresponding to the corresponding temperature detection device for a set second dwell time when the air guide plate moves to the air outlet range corresponding to the corresponding temperature detection device; wherein the set second dwell time is greater than the set first dwell time, and the set second dwell time is, for example, 1 second. The specific functions and further processing of the control unit 104 are described in step S660.

[0220] Figure 13 This is a flow chart of the air supply process of mode A of the present invention. Figure 13 As shown, air supply method A: the upper and lower left and right air guide components operate alternately, and the upper and lower air guide components operate independently, and during the process, the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the incoming air, the difference β1 between the temperature detected by the lower temperature detection device and the lower temperature of the incoming air, and the difference γ1 between the temperature detected by the middle vertical direction temperature detection device and the middle temperature of the incoming air are continuously judged.

[0221] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed of the upper left and right air guide plates is increased by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0222] If β1≤t1, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<β1≤t2, when the lower left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤β1<t4, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤β1, when the lower left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0223] If γ1≤t1, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<γ1≤t2, when the upper and lower air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤γ1<t4, when the upper and lower air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤γ1, when the upper and lower air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0224] In the solution of the present invention, this operating mode (i.e., mode A air supply) can increase the air disturbance in the room, improve the temperature uniformity in the room, increase the temperature drop rate, and quickly cool the room to approach the set temperature.

[0225] Figure 15 This is a flow chart of the D-mode air supply process of the present invention. Figure 15 As shown, mode D air supply: The upper and lower left and right air guide assemblies operate alternately, while the upper and lower air guide assemblies operate independently. During this process, the difference α2 between the temperature detected by the upper temperature detection device and the upper temperature of the inlet air, the difference β2 between the temperature detected by the lower temperature detection device and the lower temperature of the inlet air, and the difference γ2 between the temperature detected by the middle vertical direction temperature detection device and the middle temperature of the inlet air are continuously determined. If α2 ≤ t1, the upper left and right air guides move to the outlet angle corresponding to the corresponding temperature detection device and stay for 1 second. If t1 < α2 ≤ t2, the upper left and right air guides move to the outlet angle corresponding to the corresponding temperature detection device and stay for 0.5 seconds.

[0226] In the solution of the present invention, this operating mode (D mode air supply) can increase the room air disturbance, improve the room temperature uniformity, increase the temperature rise rate, and make the room temperature rise quickly close to the set temperature.

[0227] In some embodiments, the control unit 104, when the air conditioner is operated in the air supply mode of the two or more air guide components of the air outlet, combines the m upper air inlet temperatures with the upper average air inlet temperature, the n lower air inlet temperatures with the lower average air inlet temperature, and the p middle air inlet temperatures with the middle average air inlet temperature to adjust at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at corresponding positions, and further includes: when the air supply mode of the two or more air guide components of the air outlet is the second mode, adjusting at least one of the operating speeds and residence times of the two or more air guide components of the air outlet at corresponding positions in the second mode, specifically as follows:

[0228] The control unit 104 is further configured to, when the air supply mode of the two or more air guide assemblies at the air outlet is the second mode, determine an absolute value of a difference between each of the m upper inlet air temperatures and the upper average inlet air temperature, and record the difference as the absolute value of the temperature difference at the first air inlet angle. The specific functions and further processing of the control unit 104 are described in step S710.

[0229] The control unit 104 is further configured to determine a temperature interval within a set temperature range to which the absolute value of the temperature difference at the first air inlet angle belongs; wherein the temperature intervals include: a first interval, a second interval, a third interval, and a fourth interval with successively increasing temperature values; and, the temperature detection device corresponding to the absolute value of the temperature difference at the first air inlet angle among the m temperature detection devices is recorded as a corresponding temperature detection device; wherein, taking the absolute value of the temperature difference at the first air inlet angle as an example, the first interval is an interval where α1 ≤ t1, the second interval is an interval where t1 < α1 ≤ t2, the third interval is an interval where t3 ≤ α1 < t4, and the fourth interval is an interval where t4 ≤ α1. The specific functions and further processing of the control unit 104 are described in step S720.

[0230] The control unit 104 is further configured to, if the absolute value of the temperature difference at the first air inlet angle is within a first range, control the upper left and right air guide plates to increase their operating speed by a predetermined first coefficient when they move to the air outlet range or air outlet angle corresponding to the corresponding temperature detection device; the predetermined first coefficient is, for example, 1. The specific functions and further processing of the control unit 104 are described in step S730.

[0231] The control unit 104 is further configured to, if the absolute value of the temperature difference at the first air inlet angle is within a second range, control the upper left and right air guide plates to increase their operating speed by a predetermined second coefficient when they move to the air outlet range corresponding to the corresponding temperature detection device; wherein the predetermined second coefficient is less than the predetermined first coefficient, such as 1. The specific functions and further processing of the control unit 104 are described in step S740.

[0232] The control unit 104 is further configured to control the upper left and right air guide plates to remain within the air outlet range corresponding to the corresponding temperature detection device for a predetermined first dwell time when the absolute value of the temperature difference at the first air inlet angle is within a third range; the predetermined first dwell time is, for example, 0.5 seconds. The specific functions and further processing of the control unit 104 are described in step S750.

[0233] The control unit 104 is further configured to, if the absolute value of the temperature difference at the first air inlet angle is within a fourth interval, control the upper left and right air guide plates to remain within the air outlet range corresponding to the corresponding temperature detection device for a set second dwell time; wherein the set second dwell time is greater than the set first dwell time, and the set second dwell time is, for example, 1 second. The specific functions and further processing of the control unit 104 are described in step S760.

[0234] Figure 14 This is a flow chart of the air supply process of mode B of the present invention. Figure 14 As shown, air is supplied in mode B: the upper left and right air guide components are running, the lower left and right air guide components stop running and are in the minimum air outlet position, the upper and lower air guide components are fixed at the upward air guide position, and the difference α1 between the temperature detected by the upper temperature detection device and the upper temperature of the inlet air is continuously judged during the process.

[0235] If α1≤t1, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 1 times; if t1<α1≤t2, when the upper left and right air guide plates move to the air outlet range corresponding to the corresponding temperature detection device, the operating speed is increased by 0.5 times; if t3≤α1<t4, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 0.5 seconds; if t4≤α1, when the upper left and right air guide plates move to the air outlet angle corresponding to the corresponding temperature detection device, they stay for 1 second.

[0236] In the solution of the present invention, this operating mode (mode B air supply) can effectively reduce the wind sensation at the lower part of the air conditioner, improve the temperature uniformity of the room, and prevent excessive vertical temperature differences in the room.

[0237] Air supply in mode C: Both left and right air guide components stop running and are in the minimum air outlet position. The upper and lower air guide components are fixed in the upward air guide position. At this time, the temperature in the upper part of the room is close to the set temperature, and the temperature in 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 part of the air outlet to keep the room temperature stable.

[0238] According to experiments, the difference T1 can be 0°C to 2°C, preferably 1°C; the difference T2 can be -1°C to 1°C, preferably 0°C; the difference T3 can be -3°C to -1°C, preferably -2°C. The t1 can be -1°C to 0°C, preferably -0.5°C; the t2 can be -0.5°C to 0°C, preferably -0.2°C; the t3 can be 0°C to 0.5°C, preferably 0.2°C; and the t4 can be 0°C to 1°C, preferably 0.5°C.

[0239] In the solution of the present invention, this embodiment sets the maximum operating frequency of the compressor to A1>B1>C1. Because the load of the air conditioner in the cooling room will gradually decrease, the maximum operating frequency of the compressor can be reduced, thereby saving energy; in cooling mode, the air conditioner is in B mode air supply (the lower left and right air guide components are fixed at the minimum air outlet) and C mode air supply (the upper and lower left and right sweeping components are both fixed at the minimum air outlet). The overall air volume will decrease. If the frequency is not changed, the air outlet temperature will decrease. 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 conditioner is in B mode air supply and C mode air supply, it is also necessary to gradually reduce the maximum operating frequency of the compressor and increase the air outlet temperature to avoid condensation.

[0240] Figure 16 This is a flow chart of the E-mode air supply process of the present invention. Figure 16 As shown, mode E air supply: the lower left and right air guide components are in operation, the upper left and right air guide components are stopped and in the minimum air outlet position, the upper and lower air guide components are fixed in the downward air guide position, and the difference β2 between the temperature detected by the lower temperature detection device and the lower temperature of the inlet air is continuously determined during the process. If β2≤t1, the lower left and right air guide plates will stay for 1 second when they move to the air outlet angle corresponding to the corresponding temperature detection device. If t1<β2≤t2, the lower left and right air guide plates will stay for 0.5 seconds when they move to the air outlet angle corresponding to the corresponding temperature detection device. If t3≤β2<t4, the lower left and right air guide plates will increase their operating speed by 0.5 times when they move to the air outlet range corresponding to the corresponding temperature detection device. If t4≤β2, the lower left and right air guide plates will increase their operating speed by 1 time when they move to the air outlet range corresponding to the corresponding temperature detection device.

[0241] In the solution of the present invention, this operating mode (E-mode air supply) can effectively reduce the wind feeling on the upper part of the air conditioner, improve the temperature uniformity of the room, and prevent excessive vertical temperature differences in the room.

[0242] F mode air supply: Both left and right air guide components stop running and are in the minimum air outlet position, and the upper and lower air guide components are fixed in the downward air guide position. At this time, the temperature in the lower part of the room is close to the set temperature, and the temperature in the upper part of the room is slightly higher than the set temperature. The overall temperature of the room is closest to the set temperature. The air conditioner only blows out weak hot air from the lower part of the air outlet to keep the room temperature stable.

[0243] In the solution of the present invention, this embodiment sets the maximum compressor operating frequency D1>E1>F1. This is primarily because the load in the room gradually decreases during heating, allowing the maximum compressor operating frequency to be reduced, thereby saving energy. The ranges of the heating temperature differences T1, T2, and T3 are the same as for cooling, and the ranges of the temperatures t1, t2, t3, and t4 are the same as for cooling. The airflow range and airflow angle corresponding to the temperature detection device are the same as for cooling.

[0244] In the solution of the present invention, an automatic air supply control solution is adopted for the air conditioner with upper and lower separate air guides. The air supply mode of the air conditioner is adjusted according to the comparison between the ambient temperature and the set temperature of the upper and lower parts of the room, and the difference between the inlet temperature and the average temperature at different air inlet angles. This can achieve rapid temperature rise and fall, maintain high-precision temperature control, reduce the discomfort caused by the wind, and greatly improve the comfort of the air conditioner.

[0245] The solution of the present invention provides high temperature control accuracy: based on the difference between the upper and lower room temperatures and the set temperature, multiple air supply modes are alternately controlled to achieve long-term temperature control with low temperature fluctuations. The solution of the present invention provides energy saving: different maximum compressor operating frequencies are set to correspond to different room temperature differences to achieve energy saving effects, and reduce the risk of condensation in cooling mode. The solution of the present invention provides wind comfort: based on the difference between the ambient temperature and the set temperature, the air supply mode is adjusted to improve the wind discomfort problem when the ambient temperature is close to the set temperature.
