Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method, apparatus, and storage medium for an air conditioning device. Background Technology

[0002] Air conditioning devices primarily utilize air conditioners for air conditioning. In related technologies, the condenser of a modular air conditioner is located on the indoor side. To ensure the return and exhaust air between indoors and outdoors, holes need to be drilled in the exterior wall of the building. Considering the aesthetics of the building, the size and number of openings in the wall are limited, resulting in a reduction in the airflow on the condenser side. Consequently, the condenser does not cool sufficiently and cannot meet the cooling requirements of the air conditioner, leading to a poor user experience. Summary of the Invention

[0003] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0004] This invention provides a control method, device, and storage medium for an air conditioning device, which can assist in condenser cooling, improve the reliability of air conditioning device operation, and provide a better user experience.

[0005] In a first aspect, embodiments of the present invention provide a control method for an air conditioning device, the air conditioning device including a water receiving tray and a plurality of water-operating motors, each of the water-operating motors being mounted on the water receiving tray; the control method includes:

[0006] When the air conditioning device is in a preset operating mode, the first current temperature is obtained;

[0007] The control scenario is determined based on the first current temperature, the preset first temperature threshold, and the preset second temperature threshold;

[0008] According to the control scenario, adjust the number of water pumps turned on and the water level in the receiving tray.

[0009] The control method for an air conditioning device provided by the embodiments of the present invention has at least the following beneficial effects: when the air conditioning device is in a preset operating mode, a first current temperature is obtained; then, based on the first current temperature, a preset first temperature threshold, and a preset second temperature threshold, a control scenario is determined; subsequently, based on the control scenario, the number of water pump motors activated and the water level in the drip tray are adjusted. By adjusting the number of water pump motors activated and the water level in the drip tray, condenser cooling is assisted, thereby improving the reliability of the air conditioning device operation and providing a better user experience.

[0010] According to the control method of the air conditioning device provided in the embodiment of the present invention, the step of determining the control scenario based on the first current temperature, a preset first temperature threshold, and a preset second temperature threshold includes:

[0011] When the first current temperature is greater than the first temperature threshold and the first current temperature is less than the second temperature threshold, the control scenario is determined to be the first control scenario, wherein the first temperature threshold is less than the second temperature threshold.

[0012] In the above scheme, the control scenario is determined as the first control scenario based on the preset threshold limit, which is beneficial to adjust the number of water pumps turned on and the water level in the water receiving tray according to the first control scenario.

[0013] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the control scenario is determined to be a first control scenario, adjusting the number of water pumps turned on and the water level in the receiving tray according to the control scenario includes:

[0014] The water level to be increased in the receiving tray is determined based on the first parameter ratio and the preset upper limit of water level height, and the water level height of the receiving tray is adjusted according to the water level to be increased. The first parameter ratio is calculated based on the first current temperature, the first temperature threshold and the second temperature threshold.

[0015] Based on the first parameter ratio and the preset upper limit of the number of motors to be activated, the number of water pumps to be activated is determined, and the number of water pumps to be activated is adjusted according to the number of motors to be activated.

[0016] In the above scheme, under the first control scenario, the number of water pumps and the water level in the water tray are adjusted according to the first parameter ratio, the upper limit of the number of pumps, and the upper limit of the number of pumps to avoid insufficient cooling of the condenser.

[0017] According to the control method of the air conditioning device provided in the embodiment of the present invention, the air conditioning device further includes an outdoor fan; the first current temperature is the first exhaust temperature of the outdoor fan;

[0018] When the control scenario is determined to be the first control scenario, the method further includes:

[0019] Obtain the first rotational speed of the outdoor fan;

[0020] Based on the first rotational speed, the preset upper limit of rotational speed, and the first parameter ratio, the first rotational speed of the outdoor fan is adjusted to the second rotational speed, wherein the first parameter ratio is calculated based on the first exhaust temperature, the first temperature threshold, and the second temperature threshold.

[0021] The outdoor fan operates at the second speed for a first time, and the second exhaust temperature of the outdoor fan is obtained;

[0022] When the temperature of the second exhaust air is greater than that of the first exhaust air, adjust the number of water pumps turned on and the water level in the water receiving tray.

[0023] In the above scheme, under the first control scenario, the first current temperature is the first exhaust temperature. Based on the adjusted speed of the outdoor fan, the second exhaust temperature is obtained after the first operation. Based on the exhaust temperature comparison result, the number of water pumps turned on and the water level in the water tray are adjusted, which helps to improve the reliability of the whole machine operation.

[0024] According to the control method of the air conditioning device provided in the embodiment of the present invention, the method further includes:

[0025] When the second exhaust temperature is less than or equal to the first exhaust temperature, after the outdoor fan has been running at the second speed for a second time, return to the step of obtaining the first current temperature.

[0026] In the above scheme, based on the comparative analysis results of exhaust temperature, the second time is run, and the first current temperature is obtained. This allows for continuous adjustment based on temperature changes, making it convenient to apply to different ambient temperature scenarios.

[0027] According to the control method of the air conditioning device provided in the embodiment of the present invention, the step of determining the control scenario based on the first current temperature, a preset first temperature threshold, and a preset second temperature threshold includes:

[0028] When the first current temperature is less than or equal to the first temperature threshold, the control scenario is determined to be the second control scenario.

[0029] In the above scheme, the control scenario is determined as the second control scenario based on the preset first temperature threshold, which facilitates the subsequent determination of the number of water pumps to be turned on and the water level adjustment method of the water receiving tray based on the second control scenario.

[0030] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the control scenario is determined to be a second control scenario, adjusting the number of water pumps turned on and the water level in the water receiving tray according to the control scenario includes:

[0031] When the first current temperature is less than a preset third temperature threshold, the number of water pumps to be reduced is determined based on the ratio of the second parameter and the number of water pumps turned on. The number of water pumps turned on is then adjusted based on the number of water pumps to be reduced. The third temperature threshold is less than the first temperature threshold, and the ratio of the second parameter is calculated based on the first current temperature and the third temperature threshold.

[0032] Based on the ratio of the second parameter and the water level height of the receiving tray, the water level height to be reduced in the receiving tray is determined, and the water level height of the receiving tray is adjusted according to the water level height to be reduced.

[0033] In the above scheme, under the second control scenario, based on the preset third temperature threshold setting, the number of water pumps turned on and the water level in the water receiving tray are reduced to ensure that the first current temperature is within a reasonable range.

[0034] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the control scenario is determined to be a second control scenario, the step of adjusting the number of water pumps turned on and the water level in the water receiving tray according to the control scenario further includes:

[0035] When the first current temperature is less than a preset third temperature threshold, the outdoor fan speed to be reduced is determined based on the second parameter ratio and the first speed of the outdoor fan, and the first speed of the outdoor fan is adjusted according to the speed to be reduced, wherein the second parameter ratio is calculated based on the first current temperature and the third temperature threshold.

[0036] In the above scheme, under the second control scenario, the first speed of the outdoor fan is reduced according to the preset third temperature threshold, which is beneficial to increase the refrigerant pressure on the condenser side.

[0037] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the control scenario is determined to be a second control scenario, the method further includes:

[0038] When the first current temperature is greater than or equal to the third temperature threshold, the air conditioning device operates for a second time and returns to the step of obtaining the first current temperature.

[0039] In the above scheme, based on the third temperature threshold, the step of obtaining the first current temperature is returned, which can be adjusted according to temperature changes and has a wide range of applications.

[0040] According to the control method of the air conditioning device provided in the embodiment of the present invention, the step of determining the control scenario based on the first current temperature, a preset first temperature threshold, and a preset second temperature threshold includes:

[0041] When the first current temperature is greater than or equal to the second temperature threshold, the control scenario is determined to be the third control scenario.

[0042] In the above scheme, the control scenario is determined as the third control scenario based on the preset second temperature threshold. When the temperature is too high, it is beneficial to control the number of water pumps turned on and the water level in the water receiving tray.

[0043] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the control scenario is determined to be a third control scenario, adjusting the number of water pumps turned on and the water level in the receiving tray according to the control scenario includes:

[0044] Adjust the number of water pumps turned on to the preset maximum number of turns on, and adjust the water level in the water receiving tray to the preset maximum water level.

[0045] In the above scheme, under the third control scenario, the number of water pumps turned on and the water level in the water receiving tray are adjusted to the upper limit value according to the preset upper limit value to avoid the first temperature being too high.

[0046] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the control scenario is determined to be a third control scenario, the step of adjusting the number of water pumps turned on and the water level in the water receiving tray according to the control scenario further includes:

[0047] Adjust the first speed of the outdoor fan to the preset upper speed limit.

[0048] In the above scheme, under the third control scenario, the outdoor fan speed is adjusted to the upper limit value according to the preset upper limit value to ensure the cooling capacity.

[0049] According to the control method of the air conditioning device provided in the embodiment of the present invention, the air conditioning device further includes a compressor; the method further includes:

[0050] With the number of water pumps turned on adjusted to the upper limit and the water level in the receiving tray adjusted to the upper limit, the system operates for a third time to obtain the second current temperature.

[0051] When the second current temperature is greater than the first current temperature, the operating frequency of the compressor is controlled to be less than the preset upper limit value, and an exhaust frequency limiting alarm message is issued.

[0052] In the above scheme, during the third time period, the compressor frequency is limited based on the second current temperature to help cool the condenser.

[0053] According to the control method of the air conditioning device provided in the embodiment of the present invention, when the first current temperature is the first exhaust temperature of the outdoor fan, the method further includes:

[0054] With the number of water pump motors turned on adjusted to the preset maximum number of turns on, the first speed of the outdoor fan adjusted to the maximum speed, and the water level in the water receiving tray adjusted to the preset maximum water level, the third time is run to obtain the third exhaust temperature of the outdoor fan.

[0055] When the temperature of the third exhaust air is greater than that of the first exhaust air, the operating frequency of the compressor is controlled to be less than the preset upper limit value, and an exhaust frequency limiting alarm message is issued.

[0056] In the above scheme, after the third running time, the compressor frequency is limited based on the third exhaust temperature to assist in condenser cooling.

[0057] According to the control method for an air conditioning device provided in an embodiment of the present invention, when the control scenario is determined to be a third control scenario, the method further includes:

[0058] If the second current temperature is less than or equal to the first current temperature, the air conditioning device operates for a second time and then returns to the step of obtaining the first current temperature.

[0059] In the above scheme, the second time is run based on the second current temperature, and the step of obtaining the first current temperature is returned. This allows for real-time adjustment based on temperature changes, improving the user experience.

[0060] According to the control method of the air conditioning device provided in the embodiment of the present invention, the first current temperature is the exhaust temperature of the outdoor fan or the exhaust temperature of the compressor.

[0061] In the above scheme, detecting the exhaust temperature and the exhaust temperature helps to determine the control scenario.

[0062] In a second aspect, embodiments of the present invention also provide an air conditioning device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor executes the computer program to implement the control method of the air conditioning device as described in the first aspect.

[0081] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various implementations. Simultaneously, the steps or actions in the method description can be rearranged or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various orders in the specification and drawings are merely for the clear description of a particular embodiment and do not imply a mandatory order, unless otherwise stated that a particular order must be followed.

[0082] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0083] The serial numbers assigned to components in this document, such as "first," "second," and "third," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0084] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0085] Summer's heat often leaves people drenched in sweat while doing housework, leading many to install air conditioners to alleviate discomfort. However, reduced airflow on the condenser side can result in inadequate cooling. This insufficiency can cause the compressor to operate at higher power, increasing energy consumption and causing the compressor and control module to overheat, impacting overall system reliability. It can also lead to excessively high condenser pressure, exceeding the heat exchanger's maximum allowable pressure and posing a refrigerant leak risk. Furthermore, reduced condenser airflow decreases system cooling capacity, resulting in a poor user experience.

[0086] Based on this, embodiments of the present invention provide a control method, device, and storage medium for an air conditioning device. By adjusting the number of water pumps activated and the water level in the water tray, the reliability of the air conditioner operation is improved, resulting in a better user experience.

[0087] It should be noted that the air conditioning device can be an air conditioner, or in a kitchen environment, a combination of an air conditioner and a kitchen exhaust system. It primarily utilizes the air conditioner for air conditioning, and can be either a modular air conditioner or a split-type air conditioner. The control method of this air conditioning device can perform air conditioning functions such as cooling, exhausting, and dehumidifying the space. Taking the cooling mode of an air conditioner as an example, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0088] like Figure 1 As shown, the air conditioning unit includes multiple water pump motors 150 and a water collection tray 160. Several water pump motors 150 are arranged in the water collection tray 160. The water collection tray 160 and the water pump motors 150 are coupled to the condenser 140. The unit also includes a refrigerant circulation loop consisting of a compressor 120, a condenser 140, a throttling device 130, and an evaporator 110. A temperature sensor 180 and a water level switch 170 are installed on the refrigerant circulation loop. The temperature sensor 180 can be used to detect indoor and outdoor temperatures. By obtaining real-time temperature information, it is beneficial to adjust the operating power of the compressor 120. The unit also includes an inlet pipe (not shown in the figure) and an outlet pipe (not shown in the figure) connected to the water level switch 170, thereby enabling the water level in the water collection tray 160 to be controlled by the water level switch 170. The unit also includes a fan (not shown in the figure) coupled to the condenser 140, which is used for heat exchange.

[0089] It should be noted that when the air conditioning unit is turned on and in the preset operating mode, the compressor 120 compresses the refrigerant to obtain a high-temperature, high-pressure refrigerant, which is then sent to the condenser 140. After liquefaction in the condenser 140, the refrigerant is sent to the evaporator 110 through the throttling device 130. The evaporator 110 evaporates and absorbs heat to discharge cold air, while the evaporated refrigerant is sent back to the compressor 120, thus forming a refrigerant circulation loop. In this refrigerant circulation loop, when the condenser 140 is not sufficiently cooled, the number of water pump motors 150 that can be turned on can be adjusted based on the temperature detected by the temperature sensor 180, and the water level in the drip tray 160 can be controlled by the water level switch 170 to prevent the pressure in the condenser 140 from being too high or too low. Due to the refrigerant circulation loop, the operating power of the compressor 120 can also be adjusted, which can play an auxiliary protection role. The auxiliary protection role can also be achieved by adjusting the fan speed, the water level in the drip tray 160, and the number of water pump motors 150 that can be turned on, thus ensuring the reliable operation of the air conditioner.

[0090] The air conditioning devices described in the embodiments of this invention are for the purpose of more clearly illustrating the technical solutions of the embodiments of this invention, and do not constitute a limitation on the technical solutions provided by the embodiments of this invention. As those skilled in the art will know, with the evolution of air conditioning devices and the emergence of new application scenarios, the technical solutions provided by the embodiments of this invention are also applicable to similar technical problems.

[0091] Those skilled in the art will understand that the structure of the air conditioning device does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figures, or combine certain components, or have different component arrangements.

[0092] Based on the structure of the air conditioning device described above, various embodiments of the control method for the air conditioning device of the present invention are proposed. (See reference...) Figure 2 , Figure 2 A schematic flowchart of a control method for an air conditioning device according to an embodiment of the present invention is shown. The control method of the embodiment of the present invention includes, but is not limited to, steps S110, S120, and S130.

[0093] Step S110: When the air conditioning device is in a preset operating mode, obtain the first current temperature.

[0094] It should be noted that the preset operating modes are dehumidification, cooling, or exhaust modes, etc. After the air conditioner is adjusted to the preset operating mode, before obtaining the first current temperature, it obtains the indoor ambient temperature, outdoor ambient temperature, the initial number of water pump motors activated, and the initial water level in the drip tray. It also receives the user-set temperature and determines the compressor's initial frequency based on the set temperature, indoor ambient temperature, and outdoor ambient temperature. Operating according to the initial number of motors activated, the initial water level, and the initial frequency ensures that the cooling output matches the cooling demand. In the preset operating mode, after initialization through the above steps, the air conditioning unit runs for a period of time to obtain the detected first current temperature, which helps determine the control scenario. The running time can be 10 minutes or 15 minutes, which will not be elaborated here.

[0095] In one embodiment, the first current temperature is the exhaust temperature of the outdoor fan or the exhaust temperature of the compressor.

[0096] It is understandable that the detected compressor exhaust temperature can be used as the first current temperature, or the detected outdoor fan exhaust temperature can be used as the first current temperature. The first current temperature is the real-time temperature detected after running for a period of time in the operating mode described in step S110, which is used to determine the control scenario later.

[0097] Step S120: Determine the control scenario based on the first current temperature, the preset first temperature threshold, and the preset second temperature threshold.

[0098] It should be noted that the first temperature threshold is a preset temperature parameter, and the second temperature threshold is also a preset temperature parameter, and the second temperature threshold is greater than the first temperature threshold. For example, the first temperature threshold can be 20 degrees Celsius, and the second temperature threshold can be 35 degrees Celsius.

[0099] refer to Figure 3 Based on the first current temperature, a preset first temperature threshold, and a preset second temperature threshold, a control scenario is determined, including but not limited to the following steps:

[0100] Step S121: When the first current temperature is greater than the first temperature threshold and the first current temperature is less than the second temperature threshold, the control scenario is determined to be the first control scenario, wherein the first temperature threshold is less than the second temperature threshold.

[0101] It is understandable that, since the first temperature threshold is a preset temperature parameter and the second temperature threshold is also a preset temperature parameter, and the second temperature threshold is greater than the first temperature threshold, when the first current temperature is between the first temperature threshold and the second temperature threshold, the control scenario is determined as the first control scenario, which is beneficial for adjusting the subsequent water pumping motor, blower and water receiving tray according to the control scenario.

[0102] Step S122: When the first current temperature is less than or equal to the first temperature threshold, the control scenario is determined to be the second control scenario.

[0103] Understandably, when the first temperature threshold is greater than the first current temperature, or when the first current temperature is equal to the first temperature threshold, the control scenario is determined to be the second control scenario, which facilitates subsequent adjustment of the water pump motor, fan, and water receiving tray.

[0104] Step S123: When the first current temperature is greater than or equal to the second temperature threshold, the control scenario is determined to be the third control scenario.

[0105] Understandably, when the first current temperature is not less than the second temperature threshold, the control scenario is determined to be the third control scenario, which is used to subsequently adjust the operating mode of the water receiving pan, fan, and water pumping motor.

[0106] It should be noted that by comparing the first temperature threshold, the first current temperature, and the second temperature threshold, one of the control scenarios in steps S121 to S123 above can be determined. By determining the control scenario, it is convenient to adopt different adjustment strategies according to different control scenarios in order to quickly control the first current temperature within a reasonable range, ensure the reliability of the whole machine operation, and improve the user experience.

[0107] It should also be noted that the first control scenario, the second control scenario, and the third control scenario are all scenarios in which the operation steps to be executed are determined within a set range. In this embodiment, by comparing the first current temperature with the value of a preset temperature threshold, three different situations are obtained for the first current temperature. Based on the different temperature ranges in which the first current temperature is located, different operation steps are determined to be executed subsequently.

[0108] Step S130: Adjust the number of water pumps turned on and the water level in the receiving tray according to the control scenario.

[0109] refer to Figure 4 When it is the first control scenario, adjust the number of water pumps turned on and the water level in the receiving tray according to the control scenario, including but not limited to the following steps:

[0110] Step S131: Determine the water level height to be increased in the receiving pan according to the first parameter ratio and the preset upper limit of water level height, and adjust the water level height of the receiving pan according to the water level height to be increased. The first parameter ratio is calculated based on the first current temperature, the first temperature threshold and the second temperature threshold.

[0111] Understandably, the first parameter ratio is calculated using the following formula: A = (Tp1 - C1) / (C2 - C1), where A represents the first parameter ratio, Tp1 represents the first current temperature, C1 represents the first temperature threshold, and C2 represents the second temperature threshold. Calculating the first parameter ratio is beneficial for subsequent calculations and adjustments to the outdoor fan speed, the water level in the drip tray, and the number of pump motors. The water level in the drip tray is compared to the upper limit. When the water level is less than the upper limit, the required increase in water level is calculated. The required increase in water level is obtained using the following formula: Δh = A * (Hh), where Δh represents the required increase in water level, H represents the upper limit, A represents the first parameter ratio, and h represents the water level in the drip tray. Based on the required increase in water level, the water level in the drip tray is increased to Δh + h, thereby adjusting the water level in the drip tray to assist condenser cooling and ensure the overall cooling capacity. The upper limit of the water level is a preset water level height, which can be 30 centimeters or 35 centimeters, and will not be elaborated here.

[0112] Step S132: Determine the number of water pumps to be added to the number of pumps based on the ratio of the first parameter and the preset upper limit of the number of pumps to be added, and adjust the number of pumps to be added to the number of pumps to be added.

[0113] Understandably, after adjusting the water level in the drip tray, the number of water pump motors activated is compared to the upper limit. When the number activated is less than the upper limit, the number of water pump motors to be activated is calculated. This additional activation number is obtained using the following formula: Δn = A * (Nn), where Δn represents the additional activation number, N represents the upper limit, A represents the ratio of the first parameter, and n represents the number of water pump motors activated. Based on this additional activation number, the number of water pump motors activated is increased to Δn + n, thereby adjusting the number of activated water pump motors and assisting in the normal operation of the condenser. The upper limit for the activation number is a preset number, which can be 12 or 15, and will not be elaborated here.

[0114] It should be noted that the water level refers to the current water level in the drip tray, and the number of pumps activated refers to the current number of pumps in operation. When the water level is not lower than the upper limit, the water level in the drip tray is maintained; when the number of pumps activated is not lower than the upper limit, the number of pumps in operation is maintained. By adjusting the number of pumps in operation and the water level in the drip tray, the condenser cooling is assisted, thereby ensuring the cooling capacity of the air conditioner.

[0115] It should also be noted that, according to steps S131 to S133, the following four situations arise from comparing the number of openings with the maximum number of openings, and comparing the water level height with the maximum water level height: (1) When the water level height is less than the maximum water level in the receiving pan, and the number of openings is less than the maximum number of water pumps, the water level height and the number of openings are increased according to the water level height to be increased and the number of openings to be increased; (2) When the water level height is not less than the upper limit of the water level in the receiving pan, and the number of water pumps opened is less than the upper limit of the water pump opening, the water level height is maintained, and the number of water pumps opened is increased according to the number of openings to be increased; (3) When the water level height is not less than the maximum water level in the receiving pan, and the number of openings is not less than the upper limit of the water pump, the number of openings and the water level height are maintained; (4) When the water level height is less than the upper limit of the water level in the receiving pan, and the number of openings is not less than the maximum water pump, the number of openings is maintained, and the water level height in the receiving pan is increased according to the water level height to be increased. By adjusting any one of the above four situations, the first temperature is controlled within a reasonable range, ensuring the normal operation of the whole machine and a good user experience.

[0116] In one embodiment, the first current temperature is the first exhaust temperature of the outdoor fan, as a reference. Figure 5 In the case of the first control scenario, the method also includes, but is not limited to, the following steps:

[0117] Step S210: Obtain the first rotational speed of the outdoor fan.

[0118] It should be noted that the initial speed of the outdoor fan and the initial frequency of the compressor are determined based on the set temperature, indoor temperature, and outdoor temperature. Operating according to the initial number of fans activated, the initial water level, the initial speed, and the initial frequency ensures that the cooling output matches the cooling demand. The initial speed is the real-time speed of the outdoor fan detected after running for a period of time under the operating mode described in step S110. Obtaining the initial speed is beneficial for calculating and adjusting the speed of the outdoor fan based on it.

[0119] Step S220: Adjust the first speed of the outdoor fan to the second speed according to the first speed, the preset upper limit of the speed and the first parameter ratio, wherein the first parameter ratio is calculated based on the first exhaust temperature, the first temperature threshold and the second temperature threshold.

[0120] It should be noted that the first parameter ratio is calculated using the following formula: A = (Tp2 - C1) / (C2 - C1), where A represents the first parameter ratio, Tp2 represents the first exhaust temperature (equivalent to the first current temperature), C1 represents the first temperature threshold, and C2 represents the second temperature threshold. Calculating the first parameter ratio helps adjust the outdoor fan speed. The second speed is obtained using the following formula: L2 = L1 + A * (Lmax - L1), where L2 represents the second speed, L1 represents the first speed, A represents the first parameter ratio, and Lmax represents the upper limit of the speed. Operating at the obtained second speed ensures that the exhaust temperature remains within a reasonable range.

[0121] Step S230: The outdoor fan runs at the second speed for a first time to obtain the second exhaust temperature of the outdoor fan;

[0122] It is understandable that the second exhaust temperature is the real-time exhaust temperature of the outdoor fan after the speed adjustment is set and the fan is running at its initial operating time. Obtaining this second exhaust temperature helps determine whether to adjust the water tray and water pump motor. The initial operating time is a preset time, which can be set to 15 minutes or 20 minutes; details will not be elaborated here.

[0123] Step S240: When the temperature of the second exhaust is greater than that of the first exhaust, adjust the number of water pumps turned on and the water level in the water tray.

[0124] It is understandable that the temperature of the first exhaust air is lower than that of the second exhaust air. To ensure that the exhaust air temperature is within a reasonable range and that the condenser is cooled sufficiently, the water level in the water tray and the number of water pump motors turned on are adjusted to assist in the condenser's cooling. The adjustment of the water level in the water tray and the number of water pump motors turned on are similar to steps S132 and S133, and will not be described in detail here.

[0125] refer to Figure 6 The control method also includes, but is not limited to, step S310.

[0126] Step S310: When the second exhaust temperature is less than or equal to the first exhaust temperature, after the outdoor fan runs at the second speed for a second time, return to the step of obtaining the first current temperature.

[0127] Understandably, if the temperature of the first exhaust fan is greater than that of the second exhaust fan, or the temperature of the second exhaust fan is equal to that of the first exhaust fan, the outdoor fan is operating at normal power. After running for a second period of time, the first current temperature is re-acquired, and the cycle is repeated to ensure the reliability of the air conditioner's operation.

[0128] It should be noted that the second time is a preset time. The second time is set based on the detected first current temperature, which is either the compressor's exhaust temperature or the outdoor fan's exhaust temperature. It can be set to 40 minutes or 45 minutes, which will not be elaborated here.

[0129] refer to Figure 7 When it is the second control scenario, adjust the number of water pumps turned on and the water level in the receiving tray according to the control scenario, including but not limited to the following steps:

[0130] Step S133: When the first current temperature is less than the preset third temperature threshold, the number of water pumps to be reduced is determined according to the ratio of the second parameter and the number of water pumps turned on. The number of water pumps turned on is adjusted according to the number of water pumps to be reduced. The third temperature threshold is less than the first temperature threshold. The ratio of the second parameter is calculated based on the first current temperature and the third temperature threshold.

[0131] It is understandable that the first temperature threshold is greater than the third temperature threshold, denoted as C3. The third temperature threshold can be set to 16 degrees Celsius, or it can be set according to actual conditions, which will not be elaborated here. The second parameter ratio is calculated using the following formula: B = (C3 - TP1) / C3, where B represents the second parameter ratio, TP1 represents the first current temperature, and C3 represents the third temperature threshold. When the third temperature threshold is greater than the first current temperature, the number of water pumps to be reduced by Δn is determined, where Δn = B * n, B represents the second parameter ratio, and n represents the number of water pumps to be turned on. Based on the above-derived number of water pumps to be reduced, the number of water pumps to be turned on is reduced to n - Δn, thereby controlling the number of water pumps to be turned on and providing protection.

[0132] Step S134: Determine the water level to be reduced in the receiving pan based on the ratio of the second parameter and the water level height in the receiving pan, and adjust the water level height in the receiving pan according to the water level to be reduced.

[0133] Understandably, reducing the number of water pumps activated also reduces the water level in the drip tray. The reduction in water level is denoted as Δh, which is calculated using the formula Δh = B * h, where B represents the ratio of the second parameter and h represents the water level in the drip tray. By reducing the water level in the drip tray to h - Δh based on this reduction, the water level in the drip tray is adjusted, increasing the refrigerant pressure on the condenser side, ensuring cooling capacity, and improving the user experience.

[0134] Step S135: When the first current temperature is less than the preset third temperature threshold, the outdoor fan speed to be reduced is determined according to the parameter ratio and the first speed of the outdoor fan, and the first speed of the outdoor fan is adjusted according to the speed to be reduced. The second parameter ratio is calculated based on the first current temperature and the third temperature threshold.

[0135] Understandably, when the first current temperature is the first exhaust temperature, and the third temperature threshold is greater than the first exhaust temperature, the outdoor fan speed is reduced while decreasing the water level and the number of fans activated. The speed to be reduced is obtained using the following formula: ΔL = B * L1, where ΔL represents the speed to be reduced, L1 represents the first speed, and B represents the ratio of the second parameter. Based on the speed to be reduced obtained above, the outdoor fan speed is reduced to L1 - ΔL, which helps cool the condenser, improves the reliability of the air conditioner, and enhances the user experience.

[0136] It should be noted that when the third temperature threshold is greater than the first current temperature, the water level in the drip tray and the number of water pump motors turned on can be reduced, or the water level in the drip tray, the first speed of the outdoor fan, and the number of water pump motors turned on can be reduced. All of the above methods can increase the pressure on the condenser side, ensure the cooling capacity of the whole unit, and improve the user experience.

[0137] It should be noted that in the second scenario, the following situations can all promote the pressure increase of the condenser: adjusting only the water pump motor, adjusting only the water tray, adjusting only the outdoor fan, adjusting both the water pump motor and the water tray, and adjusting both the outdoor fan, the water pump motor, and the water tray. All five situations can prevent the first temperature from being too low, which could lead to abnormal operation.

[0138] refer to Figure 8 When the control scenario is the second control scenario, the control method also includes, but is not limited to, the following steps:

[0139] Step S410: When the first current temperature is greater than or equal to the third temperature threshold, the air conditioning device runs for a second time and then returns to the step of obtaining the first current temperature.

[0140] Understandably, if the first current temperature is greater than or equal to the third temperature threshold, the outdoor fan operates normally. After running for a second time, the first current temperature is re-acquired, and the detection is repeated to monitor the air conditioner's operating status in real time, ensuring reliable operation and improving user experience.

[0141] refer to Figure 9 When it is the third control scenario, adjust the number of water pumps turned on and the water level in the receiving tray according to the control scenario, including but not limited to the following steps:

[0142] Step S136: Adjust the number of water pumps turned on to the preset upper limit of the number of turns on, and adjust the water level in the water receiving tray to the preset upper limit of the water level.

[0143] Understandably, when the first current temperature is greater than the second temperature threshold, the cooling effect of the condenser is very poor, which will lead to excessive power consumption of the whole machine. Adjust the number of water pump motors to the maximum value, and at the same time adjust the water level in the water tray to the maximum value to avoid the first current temperature being too high and improve work efficiency.

[0144] Step S137: Adjust the first speed of the outdoor fan to the preset upper speed limit.

[0145] Understandably, while adjusting the water level in the drip tray to the maximum and the number of water pump motors to the maximum, the first speed of the outdoor fan is also adjusted to the maximum to prevent the initial temperature from being too high, assist in condenser cooling, ensure condenser cooling effect, and thus ensure the reliable operation of the air conditioner.

[0146] refer to Figure 10 The control method also includes, but is not limited to, steps S510 and S520.

[0147] Step S510: With the number of water pumps turned on adjusted to the maximum number of turns on and the water level in the receiving pan adjusted to the maximum water level, run for a third time to obtain the second current temperature.

[0148] It should be noted that the second current temperature is the temperature monitored in real time during the third period when the air conditioning unit is operating at its maximum operating quantity and maximum water level. Obtaining this second current temperature facilitates subsequent comparison with the first current temperature, thereby controlling different execution steps. The third period is a preset time, which can be set to 15 minutes or 20 minutes; details will not be elaborated here.

[0149] Step S520: When the second current temperature is greater than the first current temperature, control the compressor's operating frequency to be less than the preset frequency upper limit value, and issue an exhaust frequency limiting alarm message.

[0150] It is understandable that when the first current temperature is lower than the second current temperature, even if the number of openings and water level or the number of openings, the first speed and water level have been adjusted to their respective upper limits, the detected temperature is still at a high temperature. This will affect the operation of the compressor. Adjusting the compressor's operating frequency to be lower than the upper limit will limit the frequency due to high temperature and issue an alarm message, which serves as a warning.

[0151] refer to Figure 11When the first current temperature is the first exhaust temperature of the outdoor fan, the control method also includes, but is not limited to, steps S610 and S620.

[0152] In step S610, with the number of water pump motors turned on adjusted to the preset upper limit of the number of motors turned on, the first speed of the outdoor fan adjusted to the upper limit of the speed, and the water level in the water receiving tray adjusted to the preset upper limit of the water level, the third time is run to obtain the third exhaust temperature of the outdoor fan.

[0153] It should be noted that the third exhaust temperature is the temperature of the outdoor fan monitored in real time during the third period of operation of the air conditioning unit at its maximum speed, maximum number of fans activated, and maximum water level. Obtaining the third exhaust temperature facilitates subsequent comparison with the first exhaust temperature, thereby controlling different execution steps.

[0154] Step S620: When the temperature of the third exhaust air is greater than that of the first exhaust air, control the operating frequency of the compressor to be less than the preset upper limit of frequency, and issue an alarm message for excessive exhaust temperature and frequency limitation.

[0155] It is understandable that when the temperature of the third row of air is higher than that of the first row, it indicates that the exhaust temperature of the outdoor fan is abnormal, which may lead to an increase in the power of the compressor. When the temperature of the third row is too high, the operating frequency of the compressor is adjusted to not exceed the set maximum value to limit the frequency at high temperature and to issue an alarm message to serve as a warning.

[0156] refer to Figure 12 When the control scenario is a third control scenario, the control method also includes, but is not limited to, the following steps:

[0157] Step S710: If the second current temperature is less than or equal to the first current temperature, the air conditioning device runs for a second time, and then returns to the step of obtaining the first current temperature.

[0158] Understandably, if the second current temperature is lower than the first current temperature, or if the second current temperature is equal to the first current temperature, the outdoor fan operates normally. After running for a second time, the first current temperature is re-acquired, and the cycle is repeated to monitor the air conditioner's operating status in real time, ensuring reliable operation of the entire unit and improving the user experience.

[0159] It should be noted that when adjusting the speed of the outdoor fan is involved, the first current temperature in the above steps refers to the first exhaust temperature; when the speed of the outdoor fan is not involved, the first current temperature in the above steps can refer to the first exhaust temperature of the compressor or the first exhaust temperature of the outdoor fan.

[0160] For example, the first current temperature is obtained by detecting the compressor's discharge temperature; that is, the first current temperature is the compressor's first discharge temperature. (Reference) Figure 13 The overall flow of the control method for the air conditioning device in this embodiment is as follows:

[0161] Before executing step S801, the indoor ambient temperature, outdoor ambient temperature, the initial number of water pump motors activated, and the initial water level in the drip tray are acquired. The user-set temperature is received, and the initial compressor frequency is determined based on the set temperature, indoor ambient temperature, and outdoor ambient temperature. The compressor then operates according to the initial number of motors activated, the initial water level, and the initial frequency. In the pre-set operating mode, after initialization through the above steps, the air conditioning unit ensures that the cooling output matches the cooling demand.

[0162] Step S801: Under the preset operating mode, obtain the first exhaust temperature T1. Then, proceed to step S802: If the first temperature threshold C1 is less than the first exhaust temperature and the second temperature threshold C2 is greater than the first exhaust temperature, proceed to step S803: Calculate the first parameter ratio. Then, proceed to step S805: Compare the water level in the receiving pan. If the water level is less than the upper limit, proceed to step S806: Increase the water level according to the first parameter ratio. If the water level is greater than or equal to the upper limit, proceed to step S807: Compare the number of water pump motors activated. If the number of motors activated is less than the upper limit, proceed to step S808: Increase the number of motors activated according to the first parameter ratio. If the number of motors activated is greater than or equal to the upper limit, proceed to step S809: Maintain the number of motors activated and the water level. Then, proceed to step S810: Run for a second time with the adjusted water level and number of motors activated, and return to step S801. Adjusting the water level and the number of motors activated ensures the normal operation of the condenser.

[0163] Step S801 is executed. Under the preset operating mode, the first exhaust temperature T1 is obtained. Then, step S802 is executed. If the first exhaust temperature is not greater than the first temperature threshold C1, step S811 is executed to compare the first exhaust temperature with the third temperature threshold C3. If the third temperature threshold is greater than the first exhaust temperature, step S812 is executed. Based on the ratio of the second parameter, the water level and the number of openings are reduced. Step S810 is then executed to run the system for a second time after adjusting the water level and the number of openings, before returning to step S801. By reducing the water level and the number of openings, the first exhaust temperature is prevented from being too low, thus avoiding a loss of cooling capacity in the air conditioner.

[0164] Execute step S801: In the preset operating mode, obtain the first exhaust temperature T1, then execute step S802. If the first temperature threshold C1 is greater than or equal to the first exhaust temperature, execute step S811: Compare the first exhaust temperature with the third temperature threshold C3. If the first exhaust temperature is greater than or equal to the third temperature threshold, execute step S810: Adjust the water level and the number of activated units for a second time, then return to step S801. Maintain the water level and the number of activated units to ensure the normal operation of the air conditioner.

[0165] Step S801 is executed. Under the preset operating mode, the first exhaust temperature T1 is obtained. Then, step S802 is executed. If the first exhaust temperature is not less than the second temperature threshold C2, step S804 is executed. The water level and the number of openings are both adjusted to the set upper limits. The system runs for a third time at the upper limits of the water level and the number of openings, obtaining the second exhaust temperature. Step S813 is executed. The second exhaust temperature is compared with the first exhaust temperature. If the second exhaust temperature is less than the first exhaust temperature, step S810 is executed. The system runs for a second time at the upper limits of the number of openings and the water level, returning to step S801. By adjusting the water level and the number of openings to their maximum values, the condenser is assisted in sufficient cooling, thus providing protection.

[0166] Step S801 is executed. Under the preset operating mode, the first exhaust temperature T1 is obtained. Then, step S802 is executed. If the second temperature threshold C2 is less than or equal to the first exhaust temperature, step S804 is executed. The water level and the number of opening units are adjusted to the set upper limit values. The system runs for a third time with the adjusted water level and number of opening units, and the second exhaust temperature is obtained. Step S813 is executed. The second exhaust temperature is compared with the first exhaust temperature. If the second exhaust temperature is greater than or equal to the first exhaust temperature, step S814 is executed. The compressor frequency is limited, and a warning message is issued. Then, step S810 is executed. The system runs for a second time at the limited compressor operating frequency, and then returns to step S801. Frequency limiting protection ensures the air conditioner operates normally, improving the user experience.

[0167] For example, the first current temperature is obtained by detecting the exhaust temperature of the outdoor fan; that is, the first current temperature is the first exhaust temperature of the outdoor fan. (Reference) Figure 14 The overall flow of the control method for the air conditioning device in this embodiment is as follows:

[0168] Before executing step S901, the indoor temperature, outdoor temperature, initial number of water pump motors activated, and initial water level in the drip tray are acquired. The user-set temperature is received. Based on the set temperature, indoor temperature, and outdoor temperature, the initial frequency of the compressor and the initial speed of the outdoor fan are determined, and the system operates according to the initial number of motors activated, the initial water level, the initial speed, and the initial frequency. In the pre-set operating mode, after initialization through the above steps, the air conditioning unit ensures that the cooling output matches the cooling demand.

[0169] Step S901: Under the preset operating mode, obtain the first exhaust air temperature T3 and the first speed L1. Then, proceed to step S902: If the first temperature threshold C1 is less than the first exhaust air temperature, and the first exhaust air temperature is less than the second temperature threshold C2, proceed to step S903: Compare the first speed L1 with the upper speed limit. If the first speed is less than the upper speed limit, proceed to step S904: Increase the first speed to the second speed, then proceed to step S905: Run at the second speed for a first time to obtain the second exhaust air temperature T4. If the first speed is not less than the upper speed limit, proceed to step S905: Run at the first speed for a first time to obtain the second exhaust air temperature T4. Then, proceed to step S906: Compare the first exhaust air temperature and the second exhaust air temperature. If the first exhaust air temperature is greater than or equal to the second exhaust air temperature, proceed to step S912: Run at the adjusted outdoor fan speed for a second time, then return to step S901. By keeping the water level and the number of fans open constant, the speed of the outdoor fan is adjusted to ensure the normal operation of the condenser.

[0170] Execute step S901: In the preset operating mode, obtain the first exhaust temperature T3. Then execute step S902: If the first temperature threshold C1 is less than the first exhaust temperature, and the first exhaust temperature is less than the second temperature threshold C2, execute step S903: Compare the first rotational speed L1 with the upper limit of rotational speed. If the first rotational speed is less than the upper limit of rotational speed, execute step S904: Increase the first rotational speed to the second rotational speed. Then execute step S905: Run at the second rotational speed for a first time to obtain the second exhaust temperature T4. If the first rotational speed is not less than the upper limit of rotational speed, execute step S905: Run at the first rotational speed for a first time to obtain the second exhaust temperature T4. Then execute step S906. Compare the temperatures of the first and second exhaust fans. If the first exhaust fan temperature is lower than the second exhaust fan temperature, proceed to step S907. Compare the water level in the drip tray. If the water level is lower than the upper limit, proceed to step S908 to increase the water level. If the water level is greater than or equal to the upper limit, proceed to step S909. Compare the number of pump motors activated. If the number activated is less than the upper limit, proceed to step S910 to increase the number of motors activated. If the number of motors activated is greater than or equal to the upper limit, proceed to step S911 to maintain the number of motors activated and the water level. Then proceed to step S912 to run the adjusted water level, first rotation speed, and number of motors activated for a second time, and return to step S901. Adjusting the water level, first rotation speed, and number of motors activated ensures the normal operation of the condenser.

[0171] Step S901 is executed. Under the preset operating mode, the first exhaust temperature T3 is obtained. Then, step S902 is executed. If the first temperature threshold C1 is greater than or equal to the first exhaust temperature, step S913 is executed. The first exhaust temperature is compared with the third temperature threshold C3. If the third temperature threshold is greater than the first exhaust temperature, step S914 is executed. The first rotation speed, water level, and number of activated units are reduced. Step S912 is then executed to run the adjusted first rotation speed, water level, and number of activated units for a second time, before returning to step S901. By reducing the water level, first rotation speed, and number of activated units, not only can excessively low first exhaust temperatures and loss of cooling capacity in the air conditioner be avoided, but also electricity consumption can be saved.

[0172] Step S901 is executed. Under the preset operating mode, the first exhaust air temperature T3 is obtained. Then, step S902 is executed. If the first exhaust air temperature is not greater than the first temperature threshold C1, step S913 is executed. The first exhaust air temperature is compared with the third temperature threshold C3. If the first exhaust air temperature is greater than or equal to the third temperature threshold, step S912 is executed to adjust the water level, first rotation speed, and number of activated units for a second period of operation, then the process returns to step S901. The water level, first rotation speed, and number of activated units are maintained to ensure the normal operation of the air conditioner.

[0173] Step S901 is executed. Under the preset operating mode, the first exhaust temperature T3 is obtained. Then, step S902 is executed. If the first exhaust temperature is not less than the second temperature threshold C2, step S915 is executed. The water level, first rotation speed, and number of openings are all adjusted to their set upper limits. The system runs for a third time at the upper limits of the water level, rotation speed, and number of openings, obtaining the third exhaust temperature T5. Step S916 is executed. The third exhaust temperature is compared with the first exhaust temperature. If the third exhaust temperature is less than the first exhaust temperature, step S912 is executed. The system runs for a second time at the upper limits of the number of openings and the water level, returning to step S901. By adjusting the water level, first rotation speed, and number of openings to their maximum values, the condenser is assisted in sufficient cooling, thus providing protection.

[0174] Step S901: In the preset operating mode, obtain the first exhaust temperature T3. Then, step S902: If the second temperature threshold C2 is less than the first exhaust temperature, or the second temperature threshold is equal to the first exhaust temperature, step S915: Adjust the water level, first speed, and number of openings to the set upper limit values. Run for a third time at the upper limit values ​​of the water level, speed, and number of openings to obtain the third exhaust temperature T5. Step S916: Compare the third exhaust temperature with the first exhaust temperature. If the third exhaust temperature is greater than or equal to the first exhaust temperature, step S917: Limit the compressor frequency and issue a warning message. Then, step S912: Run for a second time at the frequency-limited compressor operating frequency, and return to step S801. Through frequency limiting protection, the air conditioner operates normally, improving the user experience.
