Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, and in particular to an air conditioning control method, device, electronic equipment and storage medium. Background Technology

[0002] Currently, air conditioning systems on ships are classified into centralized air conditioning systems and independent air conditioning systems based on their air conditioning treatment settings.

[0003] In harsh environments, the primary method for controlling air conditioning on board is for the captain or senior crew to issue commands to control the operation of air conditioning units in each compartment. This method has several drawbacks, such as poor timeliness, making it impossible to promptly control the start and stop of air conditioning in extreme conditions. Furthermore, starting the air conditioning can pose a danger; for example, a strong impact could cause the unit to tip over due to vibrations from the unit's mounting brackets. However, some compartments (such as equipment rooms) are generally unattended, making it impossible to identify the risk in the event of a hazard. If all air conditioning is forcibly shut down, the ambient temperature in some critical compartments (such as cooling equipment rooms and the command center) cannot be maintained, negatively impacting comfort and even the safety of equipment operation.

[0004] Regarding the technical problem that the air conditioning control methods of ships cannot coordinate comfort and safety in harsh environments, no effective solution has yet been proposed. Summary of the Invention

[0013] The difference between the air conditioner's set temperature and the ambient temperature is compared with a threshold value.

[0014] When the difference is determined to be greater than the threshold, the compressor and / or fan of the air conditioner are controlled to operate at the operating frequency of the emergency mode, wherein the operating frequency of the emergency mode is less than the operating frequency required for the compressor and / or fan to achieve the set temperature of the air conditioner in normal mode.

[0015] Optionally, the method for calculating the frequency of operation of the emergency mode includes:

[0017] Multiply the obtained temperature difference ratio by the compressor frequency correction factor to obtain the corrected ratio;

[0018] The operating frequency of the compressor in emergency mode is obtained by subtracting the corrected ratio from the preset frequency value.

[0019] Optionally, the method for calculating the operating frequency of the emergency mode further includes: multiplying the operating frequency of the compressor in the emergency mode by the fan frequency correction coefficient to obtain the operating frequency of the fan in the emergency mode.

[0020] Optionally, it also includes: controlling the air conditioner to turn off when it is determined that the difference is less than or equal to the threshold.

[0021] Optionally, the harsh environment includes one or more of the following: an extremely cold environment where the ambient temperature is lower than a first preset temperature value; an extremely hot environment where the ambient temperature exceeds a second preset temperature value; a strong wind and wave environment where the wind and wave intensity exceeds a preset intensity value; and an overcurrent environment, wherein the second preset temperature value is greater than the first preset temperature value.

[0022] Optionally, in the aforementioned hot environment, the method further includes:

[0023] Control the operating frequency of the air conditioning cooling system.

[0024] According to another aspect of the present invention, an air conditioning control device is also provided, comprising:

[0025] A differentiated control unit is used to control the air conditioner to operate according to an operating strategy corresponding to a preset level in harsh environments.

[0026] For air conditioners that are preset to maintain normal operation even in harsh environments, control them to maintain normal operation.

[0027] For air conditioners that are preset to operate with low energy consumption in harsh environments, adjust their operating parameters according to adjustment rules that can improve their stealth and shock resistance.

[0028] For air conditioners that are preset to be forced to shut down in harsh environments, control them to shut down forcibly.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] In related technologies, the air conditioning control methods cannot balance comfort and safety in harsh environments. Currently, there is no effective solution.

[0040] To address the aforementioned problems, this invention proposes an air conditioning control method, device, electronic equipment, and storage medium to resolve the technical issue in related technologies where air conditioning control methods cannot coordinate comfort and safety in harsh environments. A detailed description follows.

[0041] Example 1

[0042] According to an embodiment of the present invention, an air conditioning control method is provided, combined with Figure 1 The method includes:

[0043] Step S101: In harsh environments, control the air conditioner to operate according to the preset level of the air conditioner and the operating strategy corresponding to the preset level.

[0044] Specifically, the preset levels can be divided into at least three categories, which are referred to as Level A, Level B, and Level C in this embodiment for ease of description.

[0045] Class A air conditioning systems must maintain normal operation even in harsh environments. For example, air conditioning systems in locations such as the ship's command center and equipment cooling tanks are classified as Class A. The command center, due to its role in the ship's entire control system, needs to ensure that the temperatures of its components are within reasonable ranges to prevent control system malfunctions and potential safety hazards. Similarly, equipment cooling tanks must also maintain temperatures within preset ranges at all times to prevent equipment overheating and related safety risks.

[0046] Class B air conditioners are permitted to operate in low-energy-consumption modes under harsh environments. For example, air conditioners in shipboard freezers and crew quarters are classified as Class B. Freezers are generally used for food storage; in harsh environments, they are allowed to reduce power consumption appropriately. While this reduces cooling efficiency, it improves the equipment's stealth and shock resistance. Similarly, crew quarters can also reduce power consumption appropriately. This may slightly decrease crew comfort, but it also enhances the equipment's stealth and shock resistance.

[0047] Class C air conditioners are those that need to be forcibly shut down in harsh environments, such as those in conference rooms and restaurants. In harsh conditions, these air conditioners are generally not used, so they can be forcibly shut down to reduce energy consumption and improve the equipment's stealth and shock resistance.

[0048] In step S101, specifically, the air conditioners of different preset categories can be controlled according to the following strategy.

[0049] Step S1011: For the air conditioner that is preset to maintain normal operation even in harsh environments, control it to maintain normal operation. That is, for Class A air conditioners, since they need to operate at full load even in harsh environments, control them to maintain normal operation.

[0050] Step S1013: For the air conditioner whose preset level is low-energy operation in harsh environments, adjust the operating parameters of the air conditioner according to the adjustment rules that can improve the stealth and / or impact resistance of the air conditioner. That is, for Class B air conditioners, their operating parameters can be adjusted according to the actual situation to improve stealth and / or impact resistance.

[0051] Step S1015: For air conditioners that are preset to require forced shutdown in harsh environments, control them to shut down. That is, for Class C air conditioners, forced shutdown can be directly controlled, further improving stealth and / or impact resistance.

[0052] In harsh environments, this embodiment performs differentiated control and energy scheduling of the air conditioner according to different preset levels to improve stealth and / or impact resistance, while maintaining a certain level of comfort in the environment. This solves the technical problem in related technologies where air conditioner control methods cannot coordinate comfort and safety in harsh environments.

[0053] As an example, all air conditioners on a ship can be connected to the ship's centralized control terminal. This can be done via a 485 communication interface or other communication interfaces. The centralized control terminal can be configured with an emergency mode button, allowing authorized personnel, such as the captain, senior officers, or other skilled professionals, to press the emergency mode button with a single press in the event of severe environmental conditions. Upon receiving the button signal, the emergency mode button determines that the ship is in a severe environment and needs to activate the emergency control mode. Based on the preset levels of each air conditioner stored in the centralized control terminal, control is performed according to the corresponding rules (see the description in the above embodiment). This emergency control button enables one-click control of air conditioning energy scheduling in severe environments, improving the timeliness of air conditioning control in such conditions.

[0054] In some embodiments, upon entering emergency mode, a corresponding prompt signal can be generated and sent to an interactive terminal located within the ship. This could involve displaying the prompt signal indicating the entry into emergency mode on a monitor, setting an indicator light to illuminate, or broadcasting a prompt via a speaker.

[0055] Step S1013, as an example, specifically includes:

[0056] The difference between the air conditioner's set temperature and the ambient temperature is compared with a threshold value.

[0057] When the difference is determined to be greater than the threshold, the compressor and / or fan of the air conditioner are controlled to operate at the operating frequency of the emergency mode, wherein the operating frequency of the emergency mode is less than the operating frequency required for the compressor and / or fan to achieve the set temperature of the air conditioner in normal mode.

[0058] In this step, when the difference between the air conditioner's set temperature and the ambient temperature exceeds the threshold, it can be confirmed that although the environment is harsh, its severity is not high. The requirement for environmental comfort outweighs the requirement for improving the air conditioning unit's stealth and shock resistance due to environmental severity. Therefore, it is necessary to adjust the operating frequency of the air conditioner compressor and / or fan. This operating frequency is lower than the frequency required to reach the set temperature in normal mode, meaning it operates in a low-energy-consumption mode. While still ensuring a certain level of comfort, the lower operating frequency compared to full-load operation in normal mode results in less vibration and noise from the air conditioning unit's mounting brackets, which is beneficial for improving shock resistance and stealth.

[0059] Conversely, when the difference is determined to be less than or equal to the threshold, the air conditioner is controlled to shut down. In this step, if the difference between the air conditioner's set temperature and the ambient temperature is determined to be less than or equal to the threshold, it is confirmed that the severity of the harsh environment is too high, and the requirements for improving the stealth and shock resistance of the air conditioning unit outweigh the requirements for environmental comfort. Therefore, the air conditioner can be directly controlled to shut down, maximizing shock resistance and stealth.

[0060] As an example, in this embodiment, the aforementioned threshold is defined as T_emergency temperature difference, representing the temperature difference between the ambient temperature required for the air conditioner to operate in emergency mode and the set temperature in harsh environments. This T_emergency temperature difference is the user's set value. As an example, the control logic described above can be expressed as follows:

[0061] Let X = ΔT - T_emergency temperature difference. Where ΔT represents the difference between ambient temperature and set temperature. The larger ΔT is, the greater the required cooling capacity. T_emergency temperature difference is a manually set value, the meaning of which is explained above.

[0062] At this point, the level of comfort and the severity of the harsh environment in emergency mode are compared using the difference X between ΔT and the emergency temperature difference T:

[0063] When X > 0, it means that the comfort requirement is greater than the severity of the emergency mode. For example, if ΔT = 15℃ and T emergency temperature difference = 5℃, it means that the room is unbearably hot and the cooling requirement is greater than the shock resistance requirement. At this time, the air conditioner will operate according to the logic of the emergency mode (as described in the example below).

[0064] When X≤0, it means that the severity of the emergency mode is greater than the comfort level. For example, if ΔT=3℃ and T_emergency_temperature_difference=5℃, it means that although the room is very hot, it is tolerable compared to the severe emergency situation. The cooling requirement is less than the impact resistance requirement, and the air conditioner is turned off at this time.

[0065] As an example, the method for calculating the frequency of emergency mode operation includes:

[0066] The temperature difference ratio is obtained by dividing the difference between the ambient temperature and the air conditioner's outlet temperature by the difference between the ambient temperature and the air conditioner's set temperature.

[0067] Multiply the obtained temperature difference ratio by the compressor frequency correction factor to obtain the corrected ratio;

[0068] The operating frequency of the compressor in emergency mode is obtained by subtracting the corrected ratio from the preset frequency value.

[0069] Based on the above introduction, its formula can be expressed as:

[0070] R1 = RK × [(T ambient temperature - T outlet air temperature) / ΔT].

[0071] Where R1 represents the operating frequency required to be controlled by the compressor, K represents the unit frequency correction coefficient, which is an inherent value and is set differently for each air conditioner model. Taking a wall-mounted air conditioner as an example, its frequency correction coefficient K = 3. R is the preset frequency value.

[0072] As an example, suppose the rated cooling capacity of the air conditioning unit is Q0 and the rated air volume is V0. At this time, the initial normal operating frequency of the compressor is 50Hz; the normal operating frequency of the fan is 50Hz.

[0073] At this time, the compressor's frequency control logic is as follows:

[0074] R1 = 70 - K × [(Ambient temperature - Outlet air temperature) / ΔT]. Wherein, ambient temperature - outlet air temperature corresponds to the compressor's cooling capacity (Q = specific heat capacity of air C × air mass flow rate m × (ambient temperature - outlet air temperature)). The larger the difference, the higher the compressor's cooling capacity at that time.

[0075] If the air conditioner to be controlled is a wall-mounted air conditioner, K=3, and the ambient temperature is 40℃, the set temperature is 20℃, ΔT=20℃, and the outlet air temperature is 15℃, then: R1=70-3×1.25=66Hz (rounded down). This control frequency is lower than the frequency required for the air conditioner to reach the set value under full load in non-severe environments. While maintaining low energy consumption operation and improving the stealth and shock resistance of the air conditioning unit, it also takes into account a certain degree of comfort.

[0076] Optionally, the calculation of the fan operating frequency includes: multiplying the compressor's operating frequency in emergency mode by the fan frequency correction coefficient to obtain the fan's operating frequency in emergency mode.

[0077] Expressed as a formula, R2 = L × R1

[0078] Where R2 represents the fan control frequency, R1 is the compressor control frequency obtained in the previous embodiment, and L is the fan frequency correction coefficient, which defaults to 1. That is, under normal circumstances, the higher the compressor frequency, the higher the fan frequency. In other words, the control logic of the fan operating frequency is similar to that of the compressor, which also improves the stealth and shock resistance of the air conditioning unit while taking into account a certain degree of comfort.

[0079] As a reference for the stealth and impact resistance of air conditioning units, the test data of compressor operating frequency, air volume, cooling capacity, noise, and vibration intensity of the unit feet can be used in Tables 1, 2, and 3 to design reasonable control logic in harsh environments, so as to improve the stealth and impact resistance of air conditioning units while taking into account a certain degree of comfort.

[0083]

[0084] Table 3. Data on air conditioning cooling capacity, noise, and vibration intensity of compressor feet at different compressor operating frequencies (20-35Hz).

[0085]

[0086] In the above embodiments, harsh environments include one or more of the following: extremely cold environments where the ambient temperature is below a first preset temperature value; extremely hot environments where the ambient temperature exceeds a second preset temperature value (wherein the second preset temperature value is greater than the first preset temperature value); strong wind and wave environments where the wind and wave intensity exceeds a preset intensity value; and current overload environments. Of course, the specific control logic after entering emergency mode may need to be adjusted accordingly for different types of harsh environments.

[0087] For example, in the aforementioned hot environment, the method further includes:

[0088] Control the operating frequency of the air conditioning cooling system. For example, you can control the frequency of the cooling water pump in a water-cooled air conditioner and increase the fan speed to ensure normal compressor pressure and oil return under hot conditions.

[0089] Figure 2 This embodiment illustrates a centralized air conditioning control method for harsh environments on a ship. The system architecture connects the air conditioners of cabins 1 through N to a centralized control terminal. Senior crew members can issue emergency mode control commands to the centralized control terminal. Upon entering emergency mode, the air conditioning is controlled differently based on cabin levels A, B, and C. For level A cabins, the air conditioners operate at full load. For level B cabins, the air conditioners enter emergency mode (the specific control logic is described in the previous embodiment and will not be repeated here). For level C cabins, the air conditioning equipment is forcibly shut down. Following this control logic, corresponding control signals are communicated back to the respective cabin air conditioners, adjusting the load according to the preset level. Simultaneously, ordinary crew members can be informed of the current emergency status via air conditioner displays or indicator lights.

[0090] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
