Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and more particularly to a control method, device, air conditioner, electronic device and storage medium. Background Technology

[0002] As grain reserve systems develop towards intelligence and green practices, the operational efficiency and energy-saving performance of grain warehouse air conditioning, a core component in ensuring food security, are receiving increasing attention. Grain warehouses need to maintain appropriate humidity levels to prevent grain from losing weight and quality due to excessive dryness, or from developing mold and pests due to excessive humidity. Proper moisture retention helps maintain grain stability and ensures storage safety and quality.

[0003] In related technologies, when the humidity inside the grain silo is within acceptable limits but the temperature is only slightly high, the air conditioning system still performs deep dehumidification. This results in an excessively high proportion of latent heat load in the cooling capacity, with the sensible heat ratio (SHR) generally below 0.6, leading to wasted dehumidification capacity. These technologies often employ "temperature priority" or "start-stop" control methods, lacking dynamic identification and coordinated adjustment capabilities for sensible heat. Furthermore, the air supply status cannot be adaptively adjusted according to actual conditions, easily causing imbalances in temperature and humidity control. Although some evaporators use variable air volume (VAV) fans, when the airflow through the evaporator is too low, the dehumidification load increases, contradicting the grain silo's moisture retention objective. In short, these related technologies suffer from problems such as excessive dehumidification, high energy consumption, and inflexible air supply parameter adjustment in grain silos.

[0038] In order to solve the technical problems of excessive dehumidification, high energy consumption and inflexible air supply parameter adjustment in the air conditioning of grain warehouses in related technologies, this disclosure provides a control method, device, equipment and storage medium.

[0039] In this disclosure, the air conditioner includes an evaporator assembly with two outlet channels: a main outlet channel and a bypass outlet channel. An evaporator is housed in the main outlet channel for heat exchange with the gas passing through it. A bypass valve is installed in the bypass outlet channel to control its opening degree. Based on parameters such as the current inlet temperature, current inlet humidity, current outlet temperature, and current outlet humidity of the evaporator, the air conditioner determines its current sensible heat ratio. Then, based on this current sensible heat ratio, the bypass ratio of the bypass valve is controlled, thereby adjusting the amount of gas passing through the bypass outlet channel in the evaporator assembly. For the space to be regulated (e.g., the grain storage space in a grain silo), because this disclosure includes a bypass outlet channel, some return air can bypass the evaporator in the evaporator assembly, thereby reducing dehumidification and increasing the sensible heat ratio. Furthermore, the bypass ratio of the bypass valve can be adjusted according to the current sensible heat ratio, thereby adjusting the amount of gas passing through the bypass air passage in the evaporator assembly, that is, adjusting the amount of gas bypassing the evaporator in the return air, so as to better match the current sensible heat ratio. This enables the air conditioner's air supply state to be adaptively adjusted based on the sensible heat ratio, which can avoid energy waste and better avoid temperature and humidity imbalance in the space to be adjusted. It solves problems such as excessive dehumidification, high energy consumption, and inflexible adjustment of air supply parameters.

[0040] In one exemplary embodiment, reference Figure 1 , Figure 3 and Figure 4 As shown, a control method is provided that can be applied to an air conditioner, which can be applied to a grain silo, i.e., the grain silo can include the aforementioned air conditioner to improve the storage effect of grain. In this embodiment, the air conditioner may include an evaporator assembly 1, which is used to discharge gas to the space to be regulated corresponding to the air conditioner, i.e., the gas discharged by the evaporator assembly 1 can be used to regulate the temperature and humidity of the space to be regulated.

[0041] For example, when air conditioning is used in a grain warehouse, the space to be regulated can refer to the grain storage space of the warehouse. The evaporator assembly 1 includes a main air outlet channel 200 and a side air outlet channel 300.

[0042] The main air outlet channel 200 is equipped with an evaporator 12 for heat exchange of the gas passing through it. The bypass air outlet channel 300 is equipped with a bypass valve 13 for controlling its opening. This means that the return air from the evaporator assembly 1 can be discharged through either the main air outlet channel 200 or the bypass air outlet channel 300. Therefore, by adjusting the opening of the bypass valve 13, the amount of gas discharged through the bypass air outlet channel 300 in the return air can be adjusted, thereby regulating the ratio of gas that has undergone heat exchange with the evaporator 12 to gas that has not, thus adjusting the air conditioning supply status.

[0043] In addition, in the air conditioner of this embodiment, reference Figure 3 As shown, in addition to the evaporator assembly 1, the air conditioner may also include a main body 2, which includes a housing 26, a compressor 21, an oil separator 22, a gas-liquid separator 23, an electronic expansion valve 24, and a four-way valve 25, among other components. The compressor 21, oil separator 22, gas-liquid separator 23, electronic expansion valve 24, and four-way valve 25 are housed within the housing 26. The air conditioner may also include a condenser assembly 3, which condenses a housing 33, a condenser 31, and a condensing fan 32. The housing of the condenser assembly 3 is referred to as the condensing housing 33. The condenser 31 and the condensing fan 32 are housed within the condensing housing 33, and the condensing fan 32 is the fan that works in conjunction with the condenser 31. The connection relationships between the components in the air conditioner can be found in [reference needed]. Figure 3 As shown, it will not be elaborated upon here.

[0044] In this embodiment, reference Figure 1 As shown, the control method may include: S110: Obtain the current inlet air temperature, current inlet air humidity, current outlet air temperature, and current outlet air humidity of the evaporator; S120. Based on the current intake air temperature, current intake air humidity, current outlet air temperature, and current outlet air humidity, determine the current sensible heat ratio of the air conditioner; S130. Based on the current sensible heat ratio, control the bypass ratio of the bypass valve.

[0045] In step S110, the current inlet temperature of the evaporator 12 refers to the temperature of the gas currently entering the evaporator 12, which is also the temperature of the gas currently entering the main outlet channel 200; the current inlet humidity of the evaporator 12 refers to the humidity of the gas currently entering the evaporator 12, which is also the humidity of the gas currently entering the main outlet channel 200; the current outlet temperature of the evaporator 12 refers to the temperature of the gas currently exiting the evaporator 12, which is also the temperature of the gas currently exiting from the main outlet channel 200; and the current outlet humidity of the evaporator 12 refers to the humidity of the gas currently exiting the evaporator 12, which is also the humidity of the gas currently exiting from the main outlet channel 200.

[0046] In this step, temperature and humidity sensors can be installed on the inlet and outlet sides of the evaporator 12 to detect the current inlet temperature, current inlet humidity, current outlet temperature, and current outlet humidity. These data are then transmitted to the air conditioner's controller, allowing the controller to obtain the current inlet temperature, current inlet humidity, current outlet temperature, and current outlet humidity of the evaporator 12. Alternatively, temperature and humidity sensors (i.e., devices with both temperature and humidity detection functions) can be installed on both the inlet and outlet sides of the evaporator 12 to detect the current inlet temperature, current inlet humidity, current outlet temperature, and current outlet humidity; this is not limited. The temperature sensor can be, for example, a temperature-sensing bulb or a temperature sensor. The humidity sensor can be, for example, a humidity sensor.

[0047] Specifically, the temperature and humidity sensors installed on the air inlet side of the evaporator 12 can be located on the air inlet side of the main air outlet channel 200. If the main air outlet channel 200 and the side air outlet channel 300 of the evaporator assembly 1 use the same air inlet, the aforementioned temperature and humidity sensors can also be located on the air inlet side of the evaporator assembly 1 or on the air inlet side of the side air outlet channel 300, without limitation.

[0048] In some implementations, reference Figure 3 and Figure 4As shown, the evaporator assembly 1 includes an evaporator shell 14, an air inlet passage 100, and an evaporator fan 11. The air inlet passage 100, the main air outlet passage 200, and the bypass air outlet passage 300 are all located within the evaporator shell 14. The shell of the evaporator assembly 1 is referred to as the evaporator shell 14. The evaporator fan 11 refers to the fan in the evaporator assembly 1. The main air outlet passage 200 and the bypass air outlet passage 300 are respectively connected to the air inlet passage 100, and the evaporator fan 11 is located within the air inlet passage 100. In this case, after the evaporator assembly 1 receives air through the air inlet passage 100, it first passes through the evaporator fan 11, then part of it enters the main air outlet passage 200, and the other part enters the bypass air outlet passage 300. The gas in the main air outlet passage 200 is discharged after heat exchange in the evaporator 12. The gas in the bypass air outlet passage 300 is discharged after passing through the bypass valve 13. In this embodiment, a first temperature detection device 101 and a first humidity detection device 102 may be installed at the air inlet of the air inlet channel 100 of the evaporator assembly 1, and a second temperature detection device 201 and a second humidity detection device 202 may be installed at the air outlet of the main air outlet channel 200. The first temperature detection device 101 is used to detect the current air inlet temperature of the evaporator assembly 1, which is also the current air inlet temperature of the evaporator 12. The first humidity detection device 102 is used to detect the current air inlet humidity of the evaporator assembly 1, which is also the current air inlet humidity of the evaporator 12. The second temperature detection device 201 is used to detect the current air outlet temperature of the evaporator 12. The second humidity detection device 202 is used to detect the current air outlet humidity of the evaporator 12.

[0049] In this embodiment, after the evaporator assembly 1 receives air through the air inlet channel 100, it first passes through the evaporator fan 11, and then the airflow is rationally distributed, with part entering the main air outlet channel 200 and the other part entering the bypass air outlet channel 300. This design allows the air conditioner to flexibly adjust the amount of gas exchanging heat through the evaporator 12 according to actual needs. When the humidity in the storage room is not excessive but the temperature is too high, the opening of the bypass valve 13 is controlled to increase the amount of gas entering the bypass air outlet channel 300 and reduce the amount of gas entering the main air outlet channel 200 (i.e., after heat exchange through the evaporator 12), thereby effectively reducing the dehumidification load. This innovative design successfully avoids the problem in the prior art of performing deep dehumidification when only cooling is needed, which leads to excessive water loss in the grain, resulting in a decrease in weight and deterioration in quality, and effectively ensures the quality stability of the grain during storage. In addition, based on the temperature and humidity data detected at the air inlet and outlet, the air conditioner can calculate the current sensible heat ratio in real time and dynamically adjust the bypass ratio of the bypass valve 13 according to the sensible heat ratio. As the bypass ratio changes, the amount of gas entering the bypass outlet channel 300 and the main outlet channel 200 changes accordingly, thereby achieving precise adaptive adjustment of the air supply status. This dynamic adjustment mechanism can ensure that the temperature and humidity in the grain silo are always in a suitable balance, effectively solving the problem of temperature and humidity control imbalance caused by the lack of dynamic identification and coordinated adjustment capabilities for sensible heat in existing technologies.

[0050] It should be noted that, in addition to obtaining the current inlet air temperature, current inlet air humidity, current outlet air temperature and current outlet air humidity of the evaporator 12 through the above methods, other methods can also be used, and there is no limitation on this.

[0051] In step S120, the current intake air temperature of the evaporator 12 is obtained. Current intake humidity Current outlet air temperature and current exhaust humidity Then, based on the current intake air humidity mentioned above... and current exhaust humidity The current intake air specific humidity and the current exhaust air specific humidity are calculated. For example, this can be based on the current intake air humidity. The current intake air specific humidity can be calculated based on the saturated water vapor pressure and total atmospheric pressure; the current exhaust air specific humidity can also be calculated based on the current exhaust air humidity, saturated water vapor pressure, and total atmospheric pressure.

[0052] In this step, after obtaining the current inlet specific humidity and the current outlet specific humidity, the current sensible heat ratio can be calculated by combining parameters such as the current inlet temperature and the current outlet temperature.

[0053] The current intake air temperature, the current outlet air temperature, the current intake air specific humidity, and the current outlet air specific humidity can be substituted into the formula. To determine the current sensible heat ratio; wherein, The current sensible heat ratio, The current intake air temperature, The current outlet air temperature, The current intake air specific humidity, The current exhaust specific humidity, For isobaric specific heat capacity, It is the latent heat of vaporization of water in the air.

[0054] It should be noted that, =1.005 kJ / (kg·k), For isobaric specific heat capacity, within the range of normal temperature (0-50℃), It can be approximated as a constant. =2450kJ / kg, This refers to the latent heat of vaporization of water in the air. The latent heat of vaporization of water is 2257 kJ / kg at 100°C, but approximately 2450 kJ / kg at around 20°C. In this embodiment... A value of 2450 kJ / kg can be used. The latent heat of vaporization and specific volume at constant pressure are related to temperature, pressure, and phase state; the values ​​under normal conditions can be used in this example.

[0055] In step S130, after obtaining the current sensible heat ratio, this step can control the bypass ratio of bypass valve 13 based on the current sensible heat ratio. The bypass ratio of bypass valve 13 can also be called the bypass degree, which can be calculated by the following formula: .in, The bypass ratio of bypass valve 13; the target opening degree of bypass valve 13 refers to the current opening degree of bypass valve 13; the maximum opening degree of bypass valve 13 refers to the maximum allowable opening degree of bypass valve 13. For example, the maximum opening degree of bypass valve 13 in this step can be 100%, that is, bypass valve 13 is in a fully open state.

[0056] If it is determined that the current sensible heat ratio is less than the target sensible heat ratio, then the bypass ratio of the bypass valve 13 is increased to [value missing]. =min( +▲R, );in, The target bypass ratio of the bypass valve 13. The current bypass ratio of the bypass valve 13 is given by ▲R, where ▲R is the set bypass ratio control value. The maximum bypass ratio is set for the bypass valve 13.

[0057] It should be noted that the target sensible heat ratio, the set maximum bypass ratio, and the set bypass ratio control value can all be set according to actual needs, and their specific values ​​are not limited. For example, among them... It can be equal to 100%, meaning that bypass valve 13 is fully open at this time. ▲R can be 2%~8%, for example, ▲R equals 5%. The min() function means to take... This represents the current bypass ratio of the unit; therefore, the improved bypass ratio is equal to the current bypass ratio. Add the increase ▲R.

[0058] In this embodiment, for the space to be regulated (e.g., the grain storage space of a grain silo), since a bypass air outlet 300 is provided, some of the return air can bypass the evaporator 12 in the evaporator assembly 1, thereby reducing the dehumidification amount and increasing the sensible heat ratio. Furthermore, the bypass ratio of the bypass valve 13 can be adjusted according to the current sensible heat ratio, thereby adjusting the amount of gas passing through the bypass air outlet 300 in the evaporator assembly 1, i.e., adjusting the amount of gas bypassing the evaporator 12 in the return air, to better match the current sensible heat ratio. This achieves adaptive adjustment of the air conditioning's air supply state based on the sensible heat ratio, avoiding energy waste and better preventing temperature and humidity imbalance in the space to be regulated. It solves problems such as excessive dehumidification, high energy consumption, and inflexible air supply parameter adjustment in air conditioning.

[0059] Furthermore, this implementation uses detection devices at the air inlet and outlet of the evaporator assembly 1 to accurately acquire gas temperature and humidity data, thereby accurately calculating the current sensible heat ratio. Based on the sensible heat ratio, the bypass ratio of the bypass valve 13 is dynamically adjusted to achieve precise adaptive regulation of the air supply state, ensuring that the temperature and humidity in the space to be regulated are always in a suitable balance, effectively solving the problem of temperature and humidity control imbalance. For example, when the humidity in the space to be regulated is not excessive but the temperature is too high, the amount of gas passing through the evaporator 12 for heat exchange can be flexibly adjusted. By controlling the opening of the bypass valve 13, the amount of gas entering the bypass outlet channel 300 is increased, and the amount of gas entering the main outlet channel 200 is reduced, thus reducing the dehumidification load. When air conditioning is applied to grain silos, it can prevent the grain stored in the silos from losing weight and deteriorating in quality due to excessive water loss, effectively ensuring the quality stability of the grain during storage. Furthermore, this embodiment can reasonably adjust the amount of gas passing through the evaporator 12, avoiding unnecessary dehumidification operations, reducing the proportion of latent heat load in the cooling capacity, and allowing the cooling capacity to be more concentrated for sensible heat treatment such as cooling, significantly improving energy utilization efficiency, reducing grain storage costs, and conforming to the trend of green and energy-saving development. The control method of this embodiment can be flexibly adjusted according to actual needs to adapt to different operating conditions. At the same time, precise control reduces the impact on the system caused by excessive temperature and humidity fluctuations, helps to extend the service life of equipment, reduce maintenance costs, and improve the overall reliability and economy of the air conditioning system.

[0060] In this implementation, if it is determined that the current sensible heat ratio is less than the target sensible heat ratio, then the bypass ratio of bypass valve 13 is increased to [a certain value]. =min( +▲R, Afterwards, if it is determined that the bypass ratio after the bypass valve 13 has reached the maximum bypass ratio set by the bypass valve 13, and it is determined that the current sensible heat ratio is less than the target sensible heat ratio, and the evaporator fan 11 in the evaporator assembly 1 is not at a high speed, then the fan speed of the evaporator fan 11 is increased. For example, the fan speed of the evaporator fan 11 is divided into low speed, medium speed, and high speed. If the evaporator fan 11 is at a low speed at this time, then the fan speed of the evaporator fan 11 is increased to medium speed; if the evaporator fan 11 is at medium speed at this time, then the fan speed of the evaporator fan 11 is increased to high speed; if the evaporator fan 11 is at high speed at this time, then the high speed is maintained.

[0061] In this embodiment, when it is determined that the current sensible heat ratio is less than the target sensible heat ratio, and the bypass ratio of the bypass valve 13 has reached the set maximum value, it indicates that adjusting the bypass valve 13 alone is insufficient to meet the precise control requirements for temperature and humidity in the grain silo. At this time, if the evaporator fan 11 is not at a high speed, increasing its speed will increase the gas flow into the evaporator assembly 1. More gas passing through the evaporator 12 for heat exchange can effectively improve the air conditioner's ability to handle sensible heat, allowing the outlet air temperature to reach the appropriate range more quickly, further narrowing the gap between the current sensible heat ratio and the target sensible heat ratio, enhancing the accuracy of temperature and humidity control in the regulated space, and ensuring the stability of the storage environment. Moreover, in this embodiment, when the bypass valve 13 adjustment is limited, reasonably adjusting the evaporator fan 11 speed avoids excessive operation of other equipment or the adoption of more complex control methods due to the inability to meet temperature and humidity requirements, thus reducing system energy consumption. For example, without adjusting the fan speed, other refrigeration components might need to operate at high power for extended periods. Increasing the fan speed achieves better regulation with relatively lower energy consumption, improving the overall energy efficiency of the air conditioning system and aligning with the green development concept of energy conservation and emission reduction. When this air conditioning system is used in grain silos, this embodiment can reduce the operating costs of the grain silos. Furthermore, this tiered regulation control method fully utilizes the regulating function of the bypass valve 13 first, adjusting the evaporator fan 11 speed only after it reaches its limit. This avoids simultaneous large-scale parameter adjustments, reducing the impact on the equipment caused by frequent and drastic changes, extending the equipment's lifespan, lowering the probability of equipment failure, and ensuring the long-term stable and reliable operation of the grain silo air conditioning system, providing a solid guarantee for safe grain storage.

[0062] In one exemplary embodiment, reference Figure 2 and Figure 3 As shown, a control method is provided that can be applied to an air conditioner, which can be applied to a grain silo, i.e., the grain silo can include the aforementioned air conditioner to improve the storage effect of grain. In this embodiment, before controlling the bypass ratio of the bypass valve 13 based on the current sensible heat ratio, the control method may include: S210. Based on the current intake air temperature and humidity, determine the target operating mode of the air conditioner; S220, Control the air conditioner to the target operating mode.

[0063] In step S210, the user can configure the target intake temperature and target intake humidity in the air conditioner according to actual needs, and the specific values ​​are not limited.

[0064] In this step, if it is determined that the current intake air temperature and the current intake air humidity meet the first condition, then the target operating mode is determined to be the energy-saving and moisturizing mode; wherein, the first condition is that the current intake air temperature is less than the target intake air temperature and the current intake air humidity is less than the target intake air humidity.

[0065] In other words, if it is determined that the current intake air temperature is lower than the target intake air temperature and the current intake air humidity is lower than the target intake air humidity, then the current intake air temperature and current intake air humidity are considered to meet the first condition. At this time, the first goal is to maximize energy saving and reduce the dehumidification amount. Therefore, the target operating mode can be determined to be the energy-saving and moisturizing mode.

[0066] If the current intake air humidity meets the second condition, then the target operating mode is determined to be the emergency dehumidification mode. The second condition is that the current intake air humidity is greater than the sum of the target intake air humidity and a set humidity threshold. The set humidity threshold can be set according to actual conditions, and its specific value is not limited. For example, the set humidity threshold can be 1%-3%, specifically 2%.

[0067] It should be noted that the sum of the target intake air humidity and the set humidity threshold can be recorded as the high humidity alarm value. When the air conditioner is used in a grain warehouse, the target intake air humidity can be the standard humidity set by the user according to the different grain crops. That is to say, if it is determined that the current intake air humidity is greater than the high humidity alarm value, it means that the current intake air humidity meets the second condition. At this time, the first goal is to reduce the moisture content in the air and reduce the sensible heat ratio.

[0068] If it is determined that the current intake air temperature and the current intake air humidity do not meet the first condition, and it is determined that the current intake air humidity does not meet the second condition, then it means that there is no need to take maximum energy saving as the first goal while reducing the dehumidification capacity, nor is it necessary to take reducing the humidity in the air as the first goal. At this time, the target operating mode can be determined as the sensible cooling priority mode.

[0069] This method can accurately determine whether to activate the energy-saving humidification mode, emergency dehumidification mode, or sensible cooling priority mode based on the actual environmental needs of the grain warehouse, thus avoiding excessive operation of the air conditioner when it is not needed and reducing energy waste.

[0070] In step S220, after determining the target operating mode, the air conditioner can be controlled to operate in the target operating mode. Specifically, when the target operating mode is determined to be an energy-saving and humidifying mode, it indicates that the primary objective is maximum energy saving and reduced dehumidification. Therefore, the bypass ratio of the bypass valve 13 can be increased to [value missing]. =min( +▲R, );in, The target bypass ratio of the bypass valve 13. The current bypass ratio of the bypass valve 13 is given by ▲R, where ▲R is the set bypass ratio control value. The maximum bypass ratio is set for the bypass valve 13.

[0071] Additionally, when the target operating mode is determined to be the energy-saving and humidity-regulating mode, the operating frequency of the air conditioner's compressor 21 can be reduced to [a lower value]. =max( , );in, The target operating frequency of the compressor 21, The minimum operating frequency is set for the compressor 21. The current operating frequency of the compressor 21 To set the frequency control value.

[0072] It should be noted that the `max()` function means taking the larger of the two values, meaning that the operating frequency of compressor 21 will not be lower than the set minimum operating frequency. The set minimum operating frequency and the set frequency control value can be set according to actual needs, and their specific values ​​are not limited. For example, the set frequency control value can be between 2Hz and 4Hz, specifically 3Hz, and the set minimum operating frequency can be 20Hz.

[0073] Furthermore, when the target operating mode is determined to be the energy-saving and humidifying mode, the evaporator fan 11 of the evaporator assembly 1 can be controlled to operate at a high speed. It should be noted that in this embodiment, the evaporator fan 11 can have three speed settings: high, medium, and low. When the fan speed is at a high speed, the air stays in the evaporator 12 for a short time, resulting in the lowest dehumidification capacity.

[0074] In this embodiment, under energy-saving and humidifying mode, by increasing the bypass ratio of the bypass valve 13, some gas is allowed to bypass the evaporator 12 and be directly discharged, reducing unnecessary work done by the compressor 21 and lowering energy consumption. Simultaneously, the operating frequency of the compressor 21 is reduced to a level not lower than the set minimum operating frequency, further saving energy while ensuring basic cooling needs are met. Furthermore, by operating the evaporator fan 11 at a high fan speed, the residence time of the air within the evaporator 12 is reduced, lowering dehumidification energy consumption. Overall, the goal of maximum energy saving is achieved, effectively reducing the operating cost of the grain silo air conditioner.

[0075] When the target operating mode is emergency dehumidification mode, it means that the first goal is to reduce the moisture content in the air and reduce the sensible heat ratio. Therefore, the bypass ratio of the bypass valve 13 can be adjusted to 0 so that all the gas entering the evaporator assembly 1 passes through the evaporator 12 and is then discharged from the evaporator assembly 1, thereby better reducing the moisture content of the gas.

[0076] Additionally, the operating frequency of the air conditioner's compressor 21 can be increased to [a higher frequency]. =min( , );in, The target operating frequency of the compressor 21, The maximum operating frequency of the compressor 21 is set. The current operating frequency of the compressor 21 To set the frequency control value. It should be noted that the maximum operating frequency can be set according to actual needs and is not limited thereto. For example, the maximum operating frequency can be set to 90Hz. In addition, at this time, the evaporator fan 11 of the evaporator assembly 1 can also be controlled to be at a low speed. When the evaporator fan 11 is at the lowest speed, the gas stays in the evaporator 12 for a longer time, and the dehumidification capacity is maximized.

[0077] When the current intake air humidity is detected to be greater than the sum of the target intake air humidity and the set humidity threshold, the target operating mode is automatically determined to be the emergency dehumidification mode. In this mode, the bypass valve 13 is adjusted to a bypass ratio of 0, so that all the gas entering the evaporator assembly 1 passes through the evaporator 12 before being discharged. At the same time, the operating frequency of the compressor 21 is increased and the evaporator fan 11 is set to a low speed to minimize the moisture content in the air. This rapid and effective dehumidification measure can promptly prevent grain from becoming moldy and spoiled due to excessive humidity, ensuring the safety of grain storage.

[0078] When the target operating mode is sensible cooling priority mode, it means that there is no need to prioritize energy saving while reducing dehumidification, nor is it necessary to prioritize reducing the humidity in the air. In this case, temperature can be controlled as the primary objective. Therefore, the operating frequency of the air conditioner compressor 21 can be controlled based on the difference between the current intake air temperature and the target intake air temperature. For example, the compressor 21 can be switched to PID (proportional-integral-derivative) control to account for temperature error. for target value .like If >0, then increase the operating frequency of compressor 21; if If the value is less than 0, the operating frequency of compressor 21 will be reduced. The specific method of this PID control will not be described in detail here.

[0079] In this embodiment, under the sensible cooling priority mode, temperature is the primary control objective. The operating frequency of the compressor 21 is precisely adjusted using PID control to ensure the grain silo temperature remains stable within a suitable range. This multi-dimensional environmental control method provides a stable and suitable storage environment for the grain, reducing grain loss caused by environmental factors.

[0080] In addition, in this embodiment, after the air conditioner is controlled to be in the target operating mode, the method in other embodiments can be used to control the bypass ratio of the bypass valve 13 and the fan speed of the evaporator fan 11 based on the current sensible heat ratio, which will not be elaborated here.

[0081] In this embodiment, each temperature and humidity sensor can be set to synchronously detect the corresponding temperature or humidity parameters at a set frequency. For example, the set frequency could be a parameter detection every 5 seconds. Once a parameter is detected, it is transmitted to the air conditioner's controller. The controller then determines the target operating mode based on the current inlet temperature, current inlet humidity, current outlet temperature, and current outlet humidity of the evaporator 12, and controls the air conditioner to operate in the target mode. It then controls the bypass ratio of the bypass valve 13 and the fan speed of the evaporator fan 11 based on the current sensible heat ratio, thus completing one control cycle. Once each temperature and humidity sensor detects new current inlet temperature, current inlet humidity, current outlet temperature, and current outlet humidity, the next control cycle can begin. This process is repeated continuously to achieve dynamic control of the air conditioner.

[0082] This method comprehensively considers the current intake air temperature and humidity, dividing the air conditioning system into three target operating modes: energy-saving humidification mode, emergency dehumidification mode, and sensible cooling priority mode. This multi-mode division can accurately match the actual needs of the grain warehouse under different environmental conditions. For example, when both the temperature and humidity inside the grain warehouse are low, it automatically switches to the energy-saving humidification mode; when the humidity is too high, it quickly enters the emergency dehumidification mode, ensuring that the grain warehouse environment is always in a suitable state for grain storage, effectively improving the accuracy of environmental control. After determining the target operating mode, key parameters such as the bypass ratio of bypass valve 13, the operating frequency of compressor 21, and the fan speed of evaporator fan 11 are dynamically adjusted according to the characteristics of different modes. For example, in the energy-saving humidification mode, by increasing the bypass ratio of bypass valve 13, decreasing the operating frequency of compressor 21, and setting evaporator fan 11 to a high fan speed, the dehumidification load is reduced while meeting energy-saving requirements; in the emergency dehumidification mode, the bypass ratio of bypass valve 13 is adjusted to 0, the operating frequency of compressor 21 is increased, and evaporator fan 11 is set to a low fan speed to minimize the air humidity. This dynamic parameter adjustment method enables precise control based on real-time environmental parameters, further improving the accuracy of grain warehouse environmental regulation. In addition, in this embodiment, temperature and humidity sensors synchronously detect parameters at a set frequency and transmit the detected parameters to the air conditioning controller. The controller determines the target operating mode and controls the air conditioning based on these parameters, then waits for new parameter detection results before resuming control, thus achieving dynamic control of the air conditioning. This cyclical dynamic control method can respond promptly to changes in the grain warehouse environment, ensuring the system remains in a stable operating state.

[0083] It should be noted that traditional grain silos generally use a full return air cooling method, where all air needs to be cooled and dehumidified through the evaporator 12, regardless of whether the humidity inside the silo exceeds the standard. This causes the system to perform deep dehumidification under high temperature and low humidity conditions, resulting in a low sensible heat ratio (often below 0.6). A large amount of cooling capacity is used for unnecessary latent heat treatment, and the grain silo loses moisture rapidly. The compressor 21 frequently starts and stops or runs for a long time, resulting in high energy consumption, low energy efficiency, and unbalanced temperature and humidity control.

[0084] To address the aforementioned issues, this application achieves coordinated and optimized control of sensible and latent heat loads by introducing a bypass channel and dynamically adjusting key parameters of the air conditioning unit. By adjusting the bypass airflow ratio, some return air bypasses the evaporator 12, reducing dehumidification and increasing the sensible heat ratio. Simultaneously, the compressor 21 frequency and fan airflow are dynamically adjusted to allocate cooling capacity as needed, reducing the compressor 21 load. Temperature and humidity control becomes more precise and stable, achieving energy-efficient grain silo environmental regulation. This systematically solves the dual technical challenges of high dehumidification requirements and high energy consumption in grain silos.

[0085] This application incorporates a bypass air passage 300 in the evaporator assembly 1 of the air conditioner, allowing some return air to bypass the evaporator 12 and be directly delivered into the hopper. By dynamically adjusting the bypass valve 13 and employing a step-by-step incremental control formula, coordinated control of the sensible and latent heat of the air is achieved. This design effectively reduces the airflow through the evaporator 12, lowers the latent heat dehumidification load, increases the proportion of sensible heat in the cooling capacity, optimizes the system's sensible heat ratio, and avoids excessive dehumidification under high-temperature and low-humidity conditions. Simultaneously, the compressor 21 load and operating time are significantly reduced, resulting in substantial energy savings in low-humidity or standby modes. This achieves refined and intelligent control of temperature and humidity, improving system operational stability and energy efficiency.

[0086] Furthermore, addressing the issues of low sensible heat ratio, excessive dehumidification, and high energy consumption caused by the fixed-frequency operation and fixed airflow of traditional grain silo air conditioning units, this application proposes a coordinated control strategy that dynamically adjusts the frequency of compressor 21 and the airflow of the fan. While meeting the silo temperature control requirements, the compressor 21 frequency is reduced to decrease cooling capacity and dehumidification, while the fan airflow is adjusted to maintain a stable supply air temperature. This optimizes the distribution of cooling capacity between sensible and latent heat, increases the sensible heat ratio, and achieves an operating mode of "sensible heat dominance and controllable latent heat." This strategy can adaptively adjust according to changes in silo temperature, humidity, and load, significantly reducing compressor 21 power consumption and overall system energy consumption, thus improving energy efficiency. When used in conjunction with a bypass channel, it can also effectively suppress temperature and humidity fluctuations, enhance system stability, and achieve efficient, intelligent, and energy-saving control of the grain silo environment.
