[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] A condensation prevention control method for an intelligent air conditioning system provided by an embodiment of the present invention can be applied in an application environment as shown in Figure 1 Specifically, the condensation prevention control method is applied in an intelligent air conditioning system, and the intelligent air conditioning system includes a client and a server (or includes a controller) as shown in Figure 1 The client communicates with the server through a network to implement condensation prevention control of the target air conditioner. Among them, the client, also known as the user side, refers to a program that provides local services for the client corresponding to the server. The client can be installed on but not limited to various personal computers, laptop computers, smart phones, tablet computers, and portable wearable devices. The server can be implemented by an independent server or a server cluster composed of multiple servers.

[0041] In an embodiment, as shown in Figure 2 A condensation prevention control method for an intelligent air conditioning system is provided. The intelligent air conditioning system includes a target air conditioner (an air conditioner dedicated to sending cold air to the refrigeration target in the computer room) and a computer room air conditioner (an air conditioner for overall environment refrigeration in the computer room). Taking the server in Figure 1 as an example for illustration, the method includes the following steps:

[0042] S201, controlling the targeted air conditioner to enter a cooling mode, and when detecting that the targeted air conditioner is in a non-condensing state, controlling the targeted air conditioner to adjust the operating state to prevent the targeted air conditioner from generating condensation; controlling the computer room air conditioner to enter a dehumidification mode;

[0043] Among them, the non-condensing state refers to the state in which the targeted air conditioner does not produce condensation when the condensation temperature in the targeted air conditioner is greater than the evaporation temperature detected by the evaporation temperature sensor, and the condensation temperature can be determined according to the ambient temperature and humidity detected by the temperature and humidity sensor built into the targeted air conditioner. In this step, the evaporation temperature in the targeted air conditioner can be reduced by adjusting the operating state of the targeted air conditioner, which is conducive to the condensation temperature in the targeted air conditioner being greater than the evaporation temperature detected by the evaporation temperature sensor, so as to prevent the targeted air conditioner from producing condensation. In addition, when the targeted air conditioner enters the cooling mode, if it is detected that the current ambient humidity of the computer room increases and increases to a humidity greater than the preset ratio detected by the temperature and humidity sensor built into the targeted air conditioner, the computer room air conditioner is controlled to enter the dehumidification mode to reduce the transition from the non-condensing state to the condensing state caused by the ambient humidity affecting the humidity of the targeted air conditioner.

[0044] S202, when it is detected that the targeted air conditioner is in a critical state of condensation, the targeted air conditioner is controlled to stop, and the computer room air conditioner is controlled to exit the dehumidification mode and enter the cooling mode;

[0045] The critical condensation state refers to the critical state of condensation when the condensation temperature in the targeted air conditioner is equal to the evaporation temperature detected by the evaporation temperature sensor, which is also a state between the non-condensation state and the condensation state. When the targeted air conditioner is in the critical condensation state, condensation may occur in the air conditioner at any time, so the targeted air conditioner is controlled to shut down, the computer room air conditioner is controlled to enter the cooling mode, and the cooling capacity of the computer room air conditioner is controlled to be equal to the cooling capacity of the targeted air conditioner in the cooling mode.

[0046] S203, when the detected current ambient humidity decreases from the first humidity threshold interval to the second humidity threshold interval, controlling the targeted air conditioner to turn on and the computer room air conditioner to turn off.

[0047] Among them, the maximum humidity limit of the first humidity threshold interval is greater than the maximum humidity limit of the second humidity threshold interval. For example, the maximum humidity limit of the first humidity threshold interval can be 70% of the humidity RH% detected by the temperature and humidity sensor in the targeted air conditioner, and the maximum humidity limit of the second humidity threshold interval can be 50% of the humidity RH%. When the detected current ambient humidity drops from less than 70% RH% to 50% RH%, it means that the humidity in the targeted air conditioner is low, and the targeted air conditioner can be controlled to be turned on and the computer room air conditioner can be controlled to be turned off.

[0048] The anti-condensation control method of this embodiment sets the priority levels of the cooling modes of the target air conditioner and the computer room air conditioner, making the priority level of the cooling mode of the target air conditioner higher than that of the computer room air conditioner. It preferentially controls the target air conditioner to enter the cooling mode, and at the same time monitors the condensation situation of the target air conditioner. When it is detected that the target air conditioner is in a non-condensation state, the operating state of the target air conditioner is adjusted to lower the evaporation temperature in the target air conditioner to prevent condensation in the target air conditioner. Moreover, the computer room air conditioner is controlled to enter the dehumidification mode to reduce the transition from the non-condensation state to the condensation state caused by the influence of the environmental humidity on the humidity of the target air conditioner. When it is detected that the target air conditioner is in a critical condensation state, the target air conditioner is controlled to shut down, and the computer room air conditioner is controlled to exit the dehumidification mode and enter the cooling mode, which is beneficial to preventing condensation in the target air conditioner; when the detected current environmental humidity drops from the first humidity threshold range to the second humidity threshold range, the target air conditioner is controlled to start up and the computer room air conditioner is controlled to shut down. During the entire anti-condensation control process, the target air conditioner and the computer room air conditioner do not enter the cooling mode simultaneously, which can greatly reduce energy consumption and at the same time take into account avoiding the condensation situation of the target air conditioner.

[0049] In one embodiment, in step S201, when it is detected that the target air conditioner is in a non-condensation state, the operating state of the target air conditioner is controlled to prevent condensation in the target air conditioner; the computer room air conditioner is controlled to enter the dehumidification mode; specifically, it includes:

[0050] S301, obtaining the current environmental humidity detected by the environmental temperature and humidity sensor in the computer room environment, the instantaneous humidity and the current environmental temperature detected by the environmental temperature and humidity sensor built in the target air conditioner, and the evaporation temperature detected by the evaporation temperature sensor built in the target air conditioner;

[0051] Among them, the environmental temperature and humidity sensor in the computer room environment is arranged in the computer room environment to obtain the current environmental humidity; the evaporator temperature sensor uses a negative temperature coefficient thermistor as the sensing element, which can achieve accurate measurement of the evaporator temperature of the air conditioning system.

[0052] S302, when the current environmental humidity is greater than a preset ratio of the instantaneous humidity and the difference between the evaporation temperature and the calculated condensation temperature is greater than a preset threshold value, a primary adjustment of the operating state is performed, including controlling the target air conditioner to maintain the current air volume and fan speed and reducing the compressor speed;

[0053] Among them, the preset ratio of the instantaneous humidity can be 70% of the instantaneous humidity RH%; the difference (Tz - Td) between the evaporation temperature Tz and the calculated condensation temperature Td is greater than the preset threshold value, and this threshold value can be 1 or 2; by reducing the compressor speed, the evaporation temperature of the evaporator is increased.

[0054] S303. After the first adjustment, if the difference between the detected evaporation temperature and the calculated dew condensation temperature is greater than the preset threshold value again, adjust the output cooling capacity according to the return air temperature of the target air conditioner; if the difference between the detected evaporation temperature and the calculated dew condensation temperature is not greater than the preset threshold value again, perform a secondary adjustment of the operating state, including controlling the target air conditioner to reduce the air volume and the compressor speed; until the difference between the detected evaporation temperature and the calculated dew condensation temperature is greater than the preset threshold value again, adjust the output cooling capacity according to the return air temperature of the target air conditioner.

[0055] Among them, the difference (Tz - Td) between the evaporation temperature Tz and the calculated dew condensation temperature Td is not greater than the preset threshold value, and this threshold value can be 1, 0, etc.

[0056] S304. When the current ambient humidity is greater than the instantaneous humidity at a preset ratio, control the computer room air conditioner to enter the dehumidification mode. Among them, the instantaneous humidity at the preset ratio can be the instantaneous humidity RH% of 70%.

[0057] The anti-dew condensation control method of this embodiment detects the current ambient humidity, the instantaneous humidity detected by the ambient temperature and humidity sensor built in the target air conditioner, and the current ambient temperature in real time, and the evaporation temperature detected by the evaporation temperature sensor. According to the difference between the evaporation temperature and the calculated dew condensation temperature, judge whether to perform a first adjustment or a second adjustment, so as to adjust the operating state of the target air conditioner when the target air conditioner is in a non-dew condensation state, reduce the evaporation temperature in the target air conditioner, and prevent the target air conditioner from generating dew condensation.

[0058] In one embodiment, in step S202, that is, when it is detected that the target air conditioner is in the dew condensation critical state, control the target air conditioner to stop running, control the computer room air conditioner to exit the dehumidification mode, and enter the refrigeration mode; specifically include:

[0059] When it is detected that the difference between the evaporation temperature and the calculated dew condensation temperature is not greater than the preset threshold value, confirm that the target air conditioner is in the dew condensation critical state, and control the compressor of the target air conditioner to stop running; when it is detected again that the difference between the evaporation temperature and the calculated dew condensation temperature is greater than the preset threshold value, control the fan speed of the target air conditioner to be increased to 100%, control the computer room air conditioner to exit the dehumidification mode, and enter the refrigeration mode.

[0060] Among them, the difference (Tz - Td) between the evaporation temperature Tz and the calculated condensation temperature Td is not greater than a preset threshold value, and the threshold value can be 1, 0, etc. After the compressor of the target air conditioner stops, if it is determined that the air conditioner is in a non-condensing state, the fan speed of the target air conditioner is controlled to increase to 100%, which plays a certain dehumidifying role. At this time, the computer room air conditioner has been switched from the dehumidifying mode to the refrigerating mode, and the computer room air conditioner undertakes the refrigerating function.

[0061] In one embodiment, in step S203, that is, when the detected current ambient humidity decreases from the first humidity threshold range to the second humidity threshold range, controlling the target air conditioner to start up and the computer room air conditioner to shut down specifically includes:

[0062] S401, when it is detected that the current ambient humidity is less than the instantaneous humidity of the first preset ratio and the current ambient temperature is less than the preset temperature, controlling the computer room air conditioner to maintain the current operating state; when it is detected that the current ambient humidity is greater than the instantaneous humidity of the first preset ratio and less than the instantaneous humidity of the second preset ratio, and the current ambient temperature is less than the preset temperature, controlling the target air conditioner to start up and the computer room air conditioner to shut down.

[0063] Among them, the instantaneous humidity of the first preset ratio can be the instantaneous humidity RH% of 70% or the instantaneous humidity RH% of 75%, etc., and the preset temperature can be 28°C or 29°C, etc.; the instantaneous humidity of the second preset ratio can be the instantaneous humidity RH% of 50% or the instantaneous humidity RH% of 55%, etc. It is equivalent to combining the current ambient humidity and the current ambient temperature to sense the change of the current temperature and humidity conditions of the target air conditioner. Specifically, when the humidity decreases and the temperature remains unchanged, the target air conditioner is controlled to start up and enter the refrigerating mode, and the computer room air conditioner is controlled to shut down.

[0064] In one embodiment, after controlling the computer room air conditioner to shut down in step S401, it further includes:

[0065] S402, when it is detected that the state where the current ambient humidity is less than the instantaneous humidity of the first preset ratio and the current ambient temperature is less than the preset temperature lasts for a preset time, controlling the computer room air conditioner to cut off the power.

[0066] Among them, the preset time can be 30 min or 40 min, etc.; by continuously monitoring for a period of time, it is detected that the target air conditioner can maintain the current humidity and temperature conditions, and the target air conditioner is in good condition, and the computer room air conditioner is no longer required to participate in the regulation, so the computer room air conditioner is controlled to shut down.

[0067] In one embodiment, in step S302, the condensation temperature is calculated according to the current ambient temperature and the instantaneous humidity; the calculation formula of the condensation temperature is as follows:

[0068] Td = T - (100 - RH) / 5

[0069] Wherein, Td is the condensation temperature, T is the current ambient temperature, and RH% is the instantaneous humidity.

[0070] In one embodiment, in step S202, when it is detected that the target air conditioner is in the condensation critical state, control the target air conditioner to stop, control the computer room air conditioner to exit the dehumidification mode, and enter the refrigeration mode; specifically including:

[0071] Input the obtained evaporation temperature and the calculated condensation temperature into the trained condensation state prediction model, and output the current condensation state result. When the condensation state result is that the target air conditioner is in the condensation critical state, control the compressor of the target air conditioner to stop; after a preset time period, when it is detected again that the condensation state result is that the target air conditioner is in the non-condensation state, control the speed of the fan of the target air conditioner to be increased to 100%, control the computer room air conditioner to exit the dehumidification mode, and enter the refrigeration mode.

[0072] Among them, the condensation state prediction model adopts a neural network with an encoder and a decoder structure. The trained condensation state prediction model can be used to predict the condensation state of the target air conditioner. The training process of the condensation state prediction model is as follows: Input the evaporation temperature data samples and condensation temperature data samples with condensation state labels into the condensation state prediction model under initial parameters, use the cross-loss entropy function to calculate the deviation between the prediction result of the condensation state prediction model and the condensation state label. When the deviation reaches the preset condition, stop the model training, update the model parameters, and obtain the trained condensation state prediction model. By intelligently judging the condensation critical state of the target air conditioner and controlling the compressor of the target air conditioner to stop, more intelligent control of the air conditioner is realized.

[0073] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

[0074] In one embodiment, a condensation prevention control device for an intelligent air conditioner system is provided. The intelligent air conditioner system includes a target air conditioner and a computer room air conditioner. This condensation prevention control device corresponds one-to-one to the condensation prevention control method in the above embodiment. As Figure 3 shown, this condensation prevention control device includes a first control module 31, a second control module 32, and a third control module 33. The detailed description of each functional module is as follows:

[0075] The first control module 31 is used to control the target air conditioner to enter the refrigeration mode. When it is detected that the target air conditioner is in a non-condensation state, it controls the target air conditioner to adjust its operating state to prevent the target air conditioner from generating condensation; it controls the computer room air conditioner to enter the dehumidification mode.

[0076] The second control module 32 is used to control the target air conditioner to stop when it is detected that the target air conditioner is in a condensation critical state, control the computer room air conditioner to exit the dehumidification mode and enter the refrigeration mode.

[0077] The third control module 33 is used to control the target air conditioner to start up and the computer room air conditioner to shut down when the detected current ambient humidity drops from the first humidity threshold range to the second humidity threshold range.

[0080] A multiple determination and adjustment sub-module is used to perform a first adjustment of the operating state when the current ambient humidity is greater than a preset ratio of the instantaneous humidity and the difference between the evaporation temperature and the calculated condensation temperature is greater than a preset threshold value. The first adjustment includes controlling the target air conditioner to maintain the current air volume and fan speed and reducing the compressor speed; after the first adjustment, if it is detected again that the difference between the evaporation temperature and the calculated condensation temperature is greater than the preset threshold value, the refrigeration capacity output is adjusted according to the return air temperature of the target air conditioner; if it is detected again that the difference between the evaporation temperature and the calculated condensation temperature is not greater than the preset threshold value, a second adjustment of the operating state is performed, including controlling the target air conditioner to reduce the air volume and the compressor speed; until it is detected again that the difference between the evaporation temperature and the calculated condensation temperature is greater than the preset threshold value, the refrigeration capacity output is adjusted according to the return air temperature of the target air conditioner.

[0084] In one embodiment, the third control module includes:

[0086] In one embodiment, the third control module further includes:

[0087] The fourth control sub-module is used to control the computer room air conditioner to cut off the power when the state that the current ambient humidity is less than the instantaneous humidity of the first preset ratio and the current ambient temperature is less than the preset temperature lasts for a preset time.

[0088] In one embodiment, the dew condensation temperature is calculated based on the current ambient temperature and the instantaneous humidity; the calculation formula of the dew condensation temperature is as follows:

[0089] Td=T - (100 - RH) / 5

[0090] Wherein, Td is the dew condensation temperature, T is the current ambient temperature, and RH% is the instantaneous humidity.

[0094] For the specific limitations of the anti-condensation control device, reference may be made to the limitations of the anti-condensation control method in the above text, which will not be elaborated here. Each module in the above anti-condensation control device can be implemented in whole or in part by software, hardware, and their combination.
