Description

Technical Field

[0001] This application relates to the field of equipment control, and more particularly to an inter-row air conditioning control method, an inter-row air conditioner, an electronic device, and a readable storage medium. Background Technology

[0002] Micro-modular data centers consist of components such as server racks, in-row air conditioners, skylights, and glass doors. They utilize a closed aisle design to manage airflow and reduce energy consumption. They offer advantages such as short lead times, rapid installation, flexible deployment, low noise, and energy efficiency, leading to their widespread adoption in newly built data centers in recent years. However, due to inadequate control methods for existing in-row air conditioner groups, uneven temperature distribution occurs within the closed aisles. This results in air conditioner fans and cooling output components operating at maximum output in areas with high temperatures, while those in areas with low temperatures operate at minimum output. This overall deviation from the efficient operating range of the cooling output components leads to reduced air conditioning energy efficiency. Summary of the Invention

[0003] This application provides a method for controlling inter-row air conditioning, an inter-row air conditioner, an electronic device, and a readable storage medium, aiming to solve the technical problem that the unreasonable control method of inter-row air conditioning groups in the prior art leads to uneven temperature distribution in the closed channel, which in turn reduces the energy efficiency of the air conditioner.

[0021] Receive the indoor fan control speed calculated by the host based on the current return air temperature, and update the indoor fan speed to the indoor fan control speed;

[0022] The system receives the air conditioning temperature control target sent by the host and sets the control parameters of the cooling capacity output component according to the air conditioning temperature control target.

[0023] Optionally, the step of setting the control parameters of the cooling capacity output component according to the air conditioning temperature control target includes:

[0024] Obtain the current working mode and determine whether the current working mode is cooling mode or dehumidification mode;

[0025] If the current working mode is dehumidification mode, the average return air humidity and the target humidity are obtained, and the control parameters of the cooling output component are calculated based on the average return air humidity and the target humidity, wherein the average return air humidity is the average value of the current return air humidity detected by each of the online units;

[0026] If the current operating mode is cooling mode, then the control parameters of the cooling output component are set according to the air conditioning temperature control target.

[0028] The target for air conditioning temperature control is determined to be either return air temperature or supply air temperature;

[0029] If the target temperature for air conditioning control is the return air temperature, then the current return air temperature and the target temperature are obtained, and the control parameters of the cooling capacity output component are calculated based on the current return air temperature and the target temperature.

[0030] If the target temperature for air conditioning control is the supply air temperature, then the current supply air temperature and the target temperature are obtained, and the control parameters of the cooling output component are calculated based on the current supply air temperature and the target temperature.

The internal fan control speed is then sent to each online unit so that each online unit operates at the specified internal fan control speed. An air conditioning temperature control target is obtained and sent to each online unit so that each online unit sets the control parameters of its cooling capacity output components according to the target. By collecting the current return air temperature detected by each online unit from the host computer and determining the internal fan control speed based on this temperature, all online units operate at the same internal fan control speed, thereby improving airflow resistance, ensuring uniform temperature distribution within the enclosed channel, and quickly eliminating hot spots.

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. 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 a part of the embodiments of the present application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0048] This invention provides an inter-row air conditioning control method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the inter-row air conditioning control method of the present invention, applied to a host computer. The method includes the following steps:

[0049] Step S110: Receive the current return air temperature sent by each online unit, and calculate the internal fan control speed based on the current return air temperature;

[0050] In this embodiment, the inter-row air conditioning is applied to a micro-module data center. See [link / reference needed]. Figure 2 , Figure 2 This is a schematic diagram of a micro-modular data center. The micro-modular data center includes a passageway door (1), server racks (2), in-row air conditioners (3), enclosed passageways (4), and a data center enclosure structure (5). The in-row air conditioners are evenly distributed among the server racks. There are multiple in-row air conditioners, each acting as an online unit. Simultaneously, one in-row air conditioner can be designated as a host, meaning there can be a situation where one in-row air conditioner serves as both an online unit and a host. The online units and the host can be connected via a serial network using an RS485 bus or CAN bus; for details, see [link to documentation]. Figure 3 The online unit is equipped with an air conditioning controller, which acquires data detected by relevant sensors. i T represents the detected supply air temperature. r H represents the detected return air temperature. rTo detect the return air humidity, the air conditioning controllers are connected in series via a bus to exchange data. In some embodiments of larger-scale micro-module data centers, the inter-row air conditioners can be divided into zones, with one inter-row air conditioner selected as the host for each zone; in some embodiments, a device with data processing capabilities can be individually set or selected as the host.

[0051] The current return air temperature refers to the temperature detected at the return air vent by the online unit. This temperature can be detected by installing a temperature sensor at the return air vent of the online unit; for details, see... Figure 4 To ensure the accuracy of current return air temperature detection, at least two return air temperature sensors 6 are installed vertically in the return air vents of the inter-row air conditioning system. The online unit can obtain the current return air temperature based on the data from multiple return air temperature sensors according to the actual application or pre-set parameters, such as using the average, maximum, or minimum value of multiple return air temperature sensor data as the current return air temperature.

[0052] Step S120: The internal fan control speed is sent to each of the online machines so that each of the online machines operates at the internal fan control speed;

[0053] After receiving the current return air temperature from each online unit, the host calculates the control speed of the indoor fan based on the current return air temperature. The control speed of the indoor fan is the speed of the indoor fan set by each online unit in the next control cycle. It can be understood that the speed of the indoor fan of each online unit is consistent within the same control cycle.

[0054] Step S130: Obtain the air conditioning temperature control target and send the air conditioning temperature control target to each of the online units, so that each of the online units sets the control parameters of the cooling capacity output component according to the air conditioning temperature control target.

[0055] The air conditioning temperature control target refers to the baseline parameter used for temperature control in an air conditioner. This target is set in the main unit, and all online units adhere to it. The air conditioning temperature control target includes the return air temperature and the supply air temperature. The supply air temperature refers to the temperature detected by the online unit at the air outlet. This temperature can be detected by installing a temperature sensor at the air outlet of the online unit. (See also...) Figure 4 To ensure the accuracy of air supply temperature detection, at least two air supply temperature sensors 8 are installed vertically in the air supply outlet of the inter-row air conditioner. The online unit can obtain the current air supply temperature based on the data from multiple air supply temperature sensors according to the actual application or pre-set, such as using the average, maximum or minimum value of multiple air supply temperature sensor data as the current air supply temperature.

[0056] The control parameters of the cooling capacity output component refer to the operating parameters of the cooling capacity output component, which may include a compressor or a water valve. When the cooling capacity output component is a compressor, the control parameter is the compressor frequency; when the cooling capacity output component is a water valve, the control parameter is the water valve opening degree. Different settings are made to the control parameters of the cooling capacity output component under different air conditioning temperature control targets, resulting in more accurate control of the cooling capacity output component.

[0057] For use in online machines, see [link / reference] Figure 5 The method includes the following steps:

[0058] Step S210: Monitor the current return air temperature in real time and send the current return air temperature to the host;

[0059] Step S220: Receive the indoor fan control speed calculated by the host based on the current return air temperature, and update the indoor fan speed to the indoor fan control speed;

[0060] Step S230: Receive the air conditioning temperature control target sent by the host, and set the control parameters of the cooling capacity output component according to the air conditioning temperature control target.

[0061] This embodiment collects the current return air temperature detected by each online unit through the host, and determines the control speed of the internal fan based on the current return air temperature. This ensures that each online unit operates at the same internal fan control speed, thereby improving airflow resistance, ensuring uniform temperature distribution in the enclosed channel, and quickly eliminating hot spots. At the same time, based on the uniform temperature distribution in the enclosed channel, each online unit calculates the control parameters of its cooling output components, making the control parameters of the cooling output components in each online unit the same or similar, thereby improving the operating energy efficiency of the inter-row air conditioning.

[0062] Furthermore, in the second embodiment of the inter-row air conditioning control method of the present invention based on the first embodiment, step S110 includes the following steps:

[0063] Step S111: Determine the maximum return air temperature with the largest temperature value among the current return air temperatures;

[0064] Step S112: Obtain the target temperature, and determine the control speed deviation value based on the target temperature and the maximum return air temperature;

[0065] Step S113: Calculate the control speed of the internal fan based on the control speed deviation value.

[0066] The maximum return air temperature is the return air temperature with the highest value among the current return air temperatures detected by each online unit. Since this embodiment achieves temperature balance within the closed channel by unifying the fan speeds of each online unit, the control speed of the internal fans needs to be calculated based on the maximum return air temperature to ensure control requirements are met for the online unit with the highest internal fan speed demand. The target temperature refers to the desired temperature, usually preset by the user. The control speed deviation value characterizes the difference between the current temperature and the target temperature. The current temperature refers to the ambient temperature of the current online unit. In different application scenarios, the current temperature can be characterized by different parameters; in this embodiment, the return air temperature is used as the current temperature. It should be noted that in other embodiments, the current temperature can also be calculated based on the supply air temperature, or by combining the supply and return air temperatures, or by using an additional temperature sensor.

[0067] The speed of the indoor fan reflects the operating intensity of the inter-row air conditioner to a certain extent. For example, in cooling mode, the faster the indoor fan speed, the faster the cooling is considered to be. Therefore, after obtaining the control speed deviation value, the control speed of the indoor fan can be calculated based on the control speed deviation value so that the inter-row air conditioner can maximize the current temperature to be close to the target temperature by operating the indoor fan control speed.

[0068] Step S112 includes the following steps:

[0069] Step S1121: Obtain the air conditioning temperature control target and determine that the air conditioning temperature control target is the return air temperature or the supply air temperature;

[0070] Step S1122: If the target temperature for air conditioning control is the return air temperature, then the value obtained by subtracting the target temperature from the maximum return air temperature is used as the control speed deviation value.

[0071] Step S1123: If the air conditioning temperature control target is the supply air temperature, then obtain the preset temperature difference value, and subtract the target temperature and the preset temperature difference value from the maximum return air temperature in sequence as the control speed deviation value.

[0072] In this embodiment, the return air temperature is used as the current temperature; therefore, when the air conditioning temperature control target is the return air temperature, the value obtained by subtracting the target temperature from the maximum return air temperature is directly used as the control speed deviation value; specifically:

[0073] e1(k)=T rmax –T s

[0074] Where e1(k) is the control speed deviation value, T rmax For the maximum return air temperature, T s The target temperature.

[0075] When the target temperature control for the air conditioner is the supply air temperature, a preset temperature difference value is used to balance the difference between the return air temperature and the supply air temperature, thereby obtaining the control speed deviation value; specifically:

[0076] e1(k)=T rmax –(T s +ΔT)

[0077] Wherein, ΔT is the preset temperature difference value.

[0078] The preset temperature difference value is used to reflect the difference between the return air temperature and the supply air temperature. The preset temperature difference value varies depending on the product and application scenario. It can be set based on actual experience and is not limited here.

[0079] Step S113 includes the following steps:

[0080] Step S1131: Calculate the speed control change based on the control speed deviation value;

[0081] Step S1132: Obtain the current internal fan speed and calculate the internal fan control speed based on the current internal fan speed and the speed control change.

[0082] The speed control change indicates the difference between the current control parameter, i.e., the current internal fan speed, and the control parameter for the next control cycle. Therefore, the control parameter for the next control cycle, i.e., the internal fan control speed, can be obtained from the current internal fan speed and the speed control change.

[0083] In this embodiment, the speed control change is calculated using a proportional-integral (PI) algorithm. Specifically,

[0084]

[0085] Where N1 is the speed control change, K is the proportional coefficient, and T is the integral coefficient.

[0086] A larger proportional gain results in a stronger proportional control effect; a larger integral gain results in a stronger integral control effect. The specific proportional and integral gains can be set based on the actual application scenario and are not limited here. Substituting the obtained control speed deviation value into the PI algorithm yields the speed control change. It should be noted that this embodiment only uses the PI algorithm as an example; other suitable algorithms can be selected based on the actual application to obtain the speed control change, and are not limited here.

[0087] After obtaining the speed control change, the sum of the current internal fan speed and the speed control change is taken as the internal fan control speed.

[0088] This embodiment can obtain accurate control speed of the internal fan.

[0089] Furthermore, in the third embodiment of the inter-row air conditioning control method of the present invention based on the first embodiment of the present invention, step S230 includes the following steps:

[0090] Step S231: Obtain the current working mode and determine whether the current working mode is cooling mode or dehumidification mode;

[0091] Generally, the operating modes of inter-row air conditioners in modular data centers mainly include cooling mode and dehumidification mode. The primary control objective in cooling mode is temperature; the primary control objective in dehumidification mode is humidity. Because the primary control objectives differ between operating modes, the control parameters of the cooling capacity output components need to be set based on different parameters for each mode.

[0092] Step S232: If the current working mode is dehumidification mode, the average return air humidity and target humidity are obtained, and the control parameters of the cooling output component are calculated based on the average return air humidity and the target humidity, wherein the average return air humidity is the average value of the current return air humidity detected by each of the online units.

[0093] The return air humidity is the humidity detected at the return air vent of the online unit. (See again...) Figure 4 At least one humidity sensor 7 can be installed at the return air vent of the online unit to detect the return air humidity. Each online unit sends the detected current return air humidity to the host unit, which calculates the average return air humidity based on the current return air humidity sent by each online unit and returns the average return air humidity to each online unit.

[0094] Target humidity refers to the humidity level that is expected to be achieved at present, which is usually preset by the user or manufacturer.

[0095] The difference between the actual humidity and the target humidity can be obtained by comparing the average return air humidity and the target humidity. This difference can then be used to determine the control parameters for the cooling output components. In this embodiment, the difference between the actual humidity and the target humidity is characterized by controlling the rotational speed deviation value. Specifically:

[0096] e2(k)=H ravg –H s

[0097] Where e2(k) is the deviation value of the cooling component, H ravg H represents the average return air humidity. s Target humidity;

[0098] In this embodiment, the PI algorithm is used to calculate the change in cooling capacity control of the cooling capacity output component. Specifically:

[0099]

[0100] Wherein, N2 is the change in cooling capacity control;

[0101] After obtaining the change in cooling capacity control, the current operating parameters of the cooling capacity output component are acquired, and the sum of the current operating parameters and the change in cooling capacity control is used as the control parameters of the cooling capacity output component.

[0102] Step S233: If the current working mode is cooling mode, then the control parameters of the cooling output component are set according to the air conditioning temperature control target.

[0103] Step S233 includes the following steps:

[0104] Step S2331: Determine that the target temperature for air conditioning control is either return air temperature or supply air temperature;

[0105] Step S2332: If the target temperature control of the air conditioner is the return air temperature, then the current return air temperature and the target temperature are obtained, and the control parameters of the cooling output component are calculated based on the current return air temperature and the target temperature.

[0106] When the return air temperature is used as the target temperature for air conditioning control, the difference between the current temperature and the target temperature in the area where the online unit is located can be obtained by comparing the current return air temperature with the target temperature. Based on this difference, the control parameters for the cooling capacity output component can be obtained, thereby reducing the difference between the current temperature and the target temperature. It should be noted that in this embodiment, when the return air temperature is used as the target temperature for air conditioning control in cooling mode, the calculation method for the control parameters of the cooling capacity output component is the same as in dehumidification mode; only the calculation of the cooling capacity component deviation value is different. Specifically, when the return air temperature is used as the target temperature for air conditioning control in cooling mode, the cooling capacity component deviation value is:

[0107] e2(k)=T r -t s

[0108] Among them, T r The current return air temperature detected by the online unit;

[0109] By substituting the obtained deviation value of the cooling capacity component into the aforementioned PI algorithm for the change in cooling capacity control, the corresponding control parameters of the cooling capacity output component can be obtained.

[0110] Step S2333: If the air conditioning temperature control target is the supply air temperature, then the current supply air temperature and the target temperature are obtained, and the control parameters of the cooling output component are calculated based on the current supply air temperature and the target temperature.

[0111] When the supply air temperature is used as the target temperature for air conditioning control, the difference between the current temperature and the target temperature in the area where the online unit is located can be obtained by comparing the current supply air temperature with the target temperature. Based on this difference, the control parameters for the cooling output component can be obtained, thereby reducing the difference between the current temperature and the target temperature. It should be noted that in this embodiment, when the supply air temperature is used as the target temperature for air conditioning control in cooling mode, the calculation method for the control parameters of the cooling output component is the same as in dehumidification mode; only the calculation of the cooling component deviation value is different. Specifically, when the supply air temperature is used as the target temperature for air conditioning control in cooling mode, the cooling component deviation value is:

[0112] e2(k)=T i –T s

[0113] Among them, T i The current supply air temperature detected by the online unit;

[0114] By substituting the obtained deviation value of the cooling capacity component into the aforementioned PI algorithm for the change in cooling capacity control, the corresponding control parameters of the cooling capacity output component can be obtained.

[0115] It should be noted that the calculation method for the control parameters of the cooling capacity output component under different modes or different air conditioning temperature control targets can be selected and set based on the actual application scenario. Different calculation methods can also be set for the control parameters of the cooling capacity output component under different modes or different air conditioning temperature control targets, which is not limited here.

[0116] This embodiment can accurately calculate the control parameters of the cooling output component.

[0117] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0118] 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. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of this application.

[0123] This inter-row air conditioning system collects the current return air temperature detected by each online unit through the main unit, and determines the control speed of the internal fan based on the current return air temperature. This ensures that all online units operate at the same internal fan control speed, thereby improving airflow resistance, ensuring uniform temperature distribution in the enclosed aisle, and quickly eliminating hot spots. At the same time, based on the uniform temperature distribution in the enclosed aisle, each online unit calculates the control parameters of its cooling capacity output components, ensuring that the control parameters of the cooling capacity output components in each online unit are the same or similar, thus improving the operating energy efficiency of the inter-row air conditioning system.
