Abstract
Description
Technical Field
[0001] The present application relates to the field of automation technology, and in particular to a method and device for automatically descaling an outdoor unit of an air conditioner, and a readable storage medium. Background Art
[0002] In order to improve the energy efficiency of data centers and promote green and low-carbon development, the use of outdoor evaporative cooling technology can make full use of the natural cooling capacity of the environment. It is not only highly efficient, but also helps reduce data centers' dependence on traditional energy and carbon emissions. It has become one of the current hot trends in the data center field.
[0003] At present, the outdoor unit of the computer room air conditioner using evaporative cooling is usually designed as a separate cooling tower or an integrated design of the refrigeration host and the cooling tower. However, no matter which method is used, because it is in an outdoor environment and is affected by the water quality of the tap water supply, and long-term evaporative cooling will cause the concentration of calcium and magnesium ions in the water pan to increase, which will inevitably lead to scaling on the outdoor spray circulation pipeline, nozzles, heat exchangers, heat dissipation fillers and water collection tanks. When scaling occurs on the circulating water pipes, nozzles, etc., it will increase water resistance, thereby affecting the circulating water flow and reducing heat dissipation; especially when scaling occurs on the outdoor unit heat exchanger, it will cause the heat transfer coefficient of the heat exchanger to decrease, which will seriously affect the heat exchange effect of the entire system, causing a series of adverse problems such as a decrease in the cooling capacity of the computer room and an increase in the temperature of the computer room.
[0004] In the prior art, the descaling and cleaning of such outdoor evaporative cooling units is usually carried out manually at regular intervals. During the maintenance process, the unit needs to be shut down, and then descaling agents are added, and then manual descaling is performed. This results in a long maintenance time for descaling, which is inefficient. If the water quality is poor or the temperature is extreme in winter or summer, the descaling cycle will be relatively extended, increasing the maintenance time and cost. Summary of the invention

[0046] After analysis, the artificial descaling method of the prior art has the following disadvantages:
[0047] 1. Low descaling efficiency: Regular manual descaling usually takes a long time and requires downtime, which will affect the normal operation and efficiency of the data center;
[0048] 2. Unstable cleaning effect: First, since cleaning work relies on manual operation, the cleaning effect may vary depending on the skill level and experience of the operator, making it difficult to ensure the consistency and thoroughness of cleaning; second, the effect of the descaling agent depends on the ambient temperature. At lower or higher temperatures, the descaling effect is poor and the efficiency is low;
[0049] 3. High cost: Regular manual cleaning requires a lot of manpower, material resources and time, which increases the cleaning cost and further increases the long-term operating cost;
[0050] 4. If the water quality is poor, the descaling cycle will be increased, further increasing the maintenance manpower and time cost.
[0051] Based on this, this application proposes an automatic descaling and control method for the evaporative cooling outdoor unit of the computer room air conditioner based on the 5G network. By adding a water quality detection sensor, an automatic dosing device for the descaling agent and an integrated control application of the isolation water tank, the automatic descaling function can be achieved without stopping the machine, without affecting the normal cooling needs of the computer room.
[0052] The present application proposes an automatic descaling and control method for the evaporative cooling outdoor unit of a computer room air conditioner based on a 5G network. Based on the high speed and low latency characteristics of the 5G network, an automatic descaling prediction model is established. By adding sensors such as water quality detection sensors and water pan temperature sensors, and automatic dosing devices for descaling agents and comprehensive control applications of isolation water tanks, automatic descaling functions without stopping the machine and remote abnormality detection and adjustment can be achieved, thereby improving the maintenance efficiency of the computer room air conditioner outdoor unit.
[0053] The advantages of this application are:
[0054] 1. Establish an automated descaling prediction model based on the 5G network to realize automatic descaling and anomaly detection functions, and improve the maintenance efficiency of the air conditioner outdoor unit in the computer room;
[0055] 2. It can achieve descaling without stopping the machine, ensuring the normal operation of the unit without affecting the temperature change of the machine room;
[0056] 3. It can change the situation that the unit has low descaling efficiency when facing low water temperature in winter and high water temperature in summer, so as to achieve efficient automatic descaling control without seasonal differences;
[0057] 4. After the agent is mixed with water, it is sprayed to the area where scale is prone to form. It can clean the places that are difficult to reach by manual descaling, thus achieving comprehensive descaling.
[0058] 5. The water receiving tank composed of isolation water tank, primary filtration and secondary filtration can achieve efficient sewage discharge;
[0059] 6. Easy maintenance, the first and second level filters can be disassembled, replaced or cleaned;
[0060] 7. The low latency characteristics based on 5G ensure that maintenance personnel can adjust descaling operations and handle other abnormalities in real time through the remote control interface.
[0061] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0062] Figure 1 A schematic diagram of an air conditioner outdoor unit with automatic descaling function provided in an embodiment of the present application, Figure 2 Another schematic diagram of an air conditioner outdoor unit with automatic descaling function provided in an embodiment of the present application is as follows Figure 1 as well as Figure 2 As shown, the interior of the air conditioner outdoor unit is mainly equipped with components such as a water pump, an isolation water tank, an automatic descaling agent delivery device (referred to as the automatic agent device in the figure), a spray area, and a water receiving tray.
[0063] Specifically, when the unit of the evaporative cooling outdoor unit of the computer room air conditioner is operating normally, the water pump transports the water in the water tank to the upper spray area through the spray pipeline and the descaling agent automatic delivery device. The sprayed water then falls into the water receiving tray and enters the water pump, and is then transported to the upper spray through the water pump, forming a working cycle.
[0064] The water sprayed in the spray area passes through the heat exchanger, heat dissipation filler, water tank, etc., and after heat exchange with the air in the process, it falls on the solid bevel and gathers in the scale precipitation area, and then enters the isolation water tank after a first-level filtration;
[0065] Among them, heat exchangers, heat dissipation fillers, water tanks and other places are often in contact with water flow and are prone to scale. The agent can be sprayed to completely remove scale and can be removed to places that are difficult to reach by manual descaling.
[0066] Among them, the scale precipitation area is formed by the combination of the first-level filtering boss and the water tank edge enclosure, which can isolate and gather the dissolved scale in a small area of the water tank for convenient and efficient sewage discharge.
[0067] Among them, the function of the primary filter device is mainly to reduce the impurities in the water entering the water tank and reduce the formation of scale, and the device can be disassembled, replaced or cleaned.
[0068] In addition, the water in the isolation water tank enters the water pump after secondary filtration, and is then transported to the upper spray through the water pump to form a cycle. After time t, the sewage electric ball valve and the water supply electric ball valve are opened;
[0069] Among them, the function of the secondary filtration device is mainly to reduce the impurities in the water entering the circulating water pump and reduce the formation of scale, and the device can be disassembled, replaced or cleaned.
[0070] Among them, time t is the start time of the automatic descaling agent delivery device. After time t, the gradually dissolved scale is concentrated and precipitated in the scale precipitation area at the water tank drain valve port.
[0071] The function of the sewage electric ball valve is to discharge the sewage with scale deposits through the sewage outlet. The sewage discharge time is, for example, 3 minutes (the time is adjustable), so as to achieve automatic descaling and sewage discharge. The function of the water replenishment electric ball valve is to ensure that the water pump will not run without water. When the water level rises to the highest water level through the water tank water level relay, the water intake is stopped.
[0072] It should be noted that the filter screens of the above-mentioned primary and secondary filtration devices should be selected according to the actual environmental water quality and other conditions, and can be referred to:
[0073] ① Coarse-pore stainless steel filter: The mesh number is between 1-80 meshes, the mesh size is large, and the water permeability is good. It is generally used for filtering large particles, such as large sand and gravel.
[0074] ②Medium-pore stainless steel filter: The mesh number is between 80-200 meshes, the mesh size is moderate, and it is suitable for general liquid and gas filtration, such as air filtration, paint filtration, etc.;
[0075] ③ Fine-pore stainless steel filter: The mesh number is between 200-500 mesh, the mesh size is small, and the filtering accuracy is high. It is suitable for high-precision liquid and gas filtration, such as particulate filtration, drinking water filtration, etc.
[0076] In addition, after the sewage discharge time is over, the sewage discharge electric ball valve and the water supply electric ball valve are automatically closed.
[0077] It should be noted that the attached drawings of the present application provide an example of the location of an automatic descaling agent delivery device, and the actual location of the automatic descaling agent delivery device can be located in the pipeline after the water pump or in the pipeline before the water pump according to specific circumstances.
[0078] In addition, the present application integrates a remote control module and necessary sensors (such as water quality detection sensors, water pan temperature sensors, and humidity, pressure, flow and other sensors) in the evaporative cooling outdoor unit of the computer room air conditioner, connects it to the 5G network communication module, and uses a descaling prediction method based on the 5G network to determine when automatic descaling is needed; wherein, the evaporative cooling outdoor unit of the computer room air conditioner includes an integrated evaporative cooling outdoor unit and a split evaporative cooling outdoor unit.
[0079] Among them, the descaling prediction method based on 5G network is:
[0080] (1) Collect the operating data of the air conditioner outdoor unit on various sensors and capture the sensor readings through IoT devices;
[0081] (2) Using 5G networks, the collected data is transmitted to cloud services in real time to establish a historical database for a certain period of time;
[0082] (3) Use appropriate data analysis tools (such as time series analysis, machine learning algorithms, etc.) to analyze historical data, identify patterns and trends in the data, and train a descaling prediction model;
[0083] (4) When the prediction model evaluates and monitors that the air conditioner outdoor unit needs to be descaled, an automatic descaling operation notification is triggered to the maintenance personnel;
[0084] (5) Collect the effect data after maintenance and feed it back to the analysis and prediction model to continuously optimize the prediction accuracy. After each descaling is completed, the descaling data is fed back to the descaling prediction model through the 5G network and the descaling completion notification is triggered to the maintenance personnel. The descaling data fed back to the descaling prediction model includes the sensor data of the entire descaling process and the system operation log, so as to continuously optimize and improve the accuracy of the descaling prediction model. The method of triggering the descaling completion notification to the maintenance personnel can rely on a web page or an application APP program so that the maintenance personnel can receive notification messages and remotely operate.
[0085] It should be noted that during the entire descaling process, the unit does not stop running, so it can still meet the normal cooling needs in the computer room.
[0086] The present application provides an automatic descaling method for an air conditioner outdoor unit. The working process of the method can be implemented by electronic devices, such as computers, handheld smart terminals, etc. In addition, it can also be implemented by a cloud server, for example, the cloud server is connected to a 5G network communication module, and the 5G network communication module is connected to a sensor (such as a water quality detection sensor, a water pan temperature sensor, and humidity, pressure, flow, etc.) to ensure that the cloud server can obtain various sensor data. For the convenience of explanation, the method execution subject is described as a cloud server in each embodiment of the present application.
[0087] Figure 3 A schematic diagram of an automatic descaling method for an air conditioner outdoor unit provided in an embodiment of the present application, such as Figure 3 As shown, the present application provides an automatic descaling method for an air conditioner outdoor unit, the method comprising S1-S3, specifically as follows:
[0088] S1. Acquire monitoring data of at least two sensors, where the at least two sensors are arranged on an outdoor unit of an air conditioner;
[0089] Specifically, the cloud server obtains monitoring data from at least two sensors (such as water quality detection sensors, water tray temperature sensors, and humidity, pressure, flow and other sensors) through the 5G network communication module to facilitate descaling analysis.
[0090] S2. Inputting the monitoring data of the at least two sensors into a pre-trained descaling prediction model to obtain a prediction result;
[0091] Among them, the descaling prediction model is trained through historical monitoring data. The descaling prediction model can be used to determine whether descaling treatment is needed. The prediction results specifically include the existence of descaling demand (i.e., descaling treatment is needed) or no descaling demand (i.e., no descaling treatment is needed).
[0092] S3. When the prediction result indicates that there is a need for descaling, automatically descaling the outdoor unit of the air conditioner.
[0093] In some embodiments, S3 includes: when the prediction result indicates that there is a need for descaling, issuing a work instruction to an automatic descaling agent dispensing device provided on the air conditioner outdoor unit, wherein the work instruction is used to instruct the automatic descaling agent dispensing device to dispense the descaling agent.
[0094] In this step, there are multiple methods for setting the dosage of the automatic descaling agent delivery device, and the following are example methods:
[0095] (1) Based on water tank capacity
[0096] Specifically, the descaling agent is used in a ratio ranging from 1:10 to 1:50 according to the volume of the water tank.
[0097] (2) Based on circulating water flow
[0098] Specifically, the specific dosage is determined according to the following formula:
[0099]
[0100] The dosage (kg / h) indicates the amount of descaling agent used in one hour, in kilograms per hour; the flow rate (m 3 / h) indicates the water flow rate in cubic meters per hour; concentration (mg / L) indicates the concentration of the descaling agent in milligrams per liter; 24 (h / d) indicates that there are 24 hours in a day in hours per day; 1000 (mg / g) indicates the conversion between milligrams and grams; concentration (%) indicates the concentration percentage of the descaling agent.
[0101] In some embodiments, the sensor includes a water pan temperature sensor, and the monitoring data includes a current water temperature monitored by the water pan temperature sensor;
[0102] When the prediction result shows that there is a need for descaling, a work instruction is issued to the automatic descaling agent dispensing device arranged on the outdoor unit of the air conditioner, including: when the prediction result shows that there is a need for descaling, it is determined whether the current water temperature monitored by the water pan temperature sensor is within a preset temperature range, and if so, a work instruction is issued to the automatic descaling agent dispensing device arranged on the outdoor unit of the air conditioner.
[0103] Specifically, since descaling agents are generally acidic substances, they have an optimal operating temperature, for example, between 20°C and 50°C. The descaling effect of the descaling agent can be maximized in this temperature range. Therefore, this embodiment also includes a water temperature detection and adjustment step.
[0104] In this step, when the unit receives the automatic descaling notification sent by the cloud server, the water pan temperature sensor feeds back the current water temperature. After the unit determines and adjusts the water temperature to reach the optimal descaling temperature, it turns on the automatic descaling agent delivery device and delivers a certain dose of the agent at a uniform speed for a period of time t (min).
[0105] It can be understood that in the present application, the judgment of the current water temperature and the control of the switching action of the automatic descaling agent delivery device can be implemented by a cloud server or by an air-conditioning outdoor unit, and the present application does not limit this.
[0106] In some embodiments, when the prediction result indicates that there is a need for descaling, a work instruction is issued to an automatic descaling agent dispensing device disposed on the air conditioner outdoor unit, and further includes: if the current water temperature monitored by the water pan temperature sensor is lower than the preset temperature range, the current water temperature is heated up, and after the current water temperature reaches the preset temperature range, a work instruction is issued to the automatic descaling agent dispensing device disposed on the air conditioner outdoor unit.
[0107] In some embodiments, the current water temperature is raised, including: sending a first adjustment instruction to the air conditioner outdoor unit, wherein the first adjustment instruction is used to instruct the air conditioner outdoor unit to reduce the water pump flow and the fan speed.
[0108] In some embodiments, when the prediction result indicates that there is a need for descaling, a work instruction is issued to an automatic descaling agent dispensing device disposed on the air conditioner outdoor unit, and further includes: if the current water temperature monitored by the water pan temperature sensor is higher than the preset temperature range, the current water temperature is cooled, and after the current water temperature reaches the preset temperature range, a work instruction is issued to the automatic descaling agent dispensing device disposed on the air conditioner outdoor unit.
[0109] In some embodiments, the current water temperature is cooled down, including:
[0110] A second adjustment instruction is issued to the air conditioner outdoor unit, wherein the second adjustment instruction is used to instruct the air conditioner outdoor unit to increase the water pump flow rate and the fan speed.
[0111] For ease of understanding, the following is an example of how the unit determines and adjusts the water temperature to reach the optimal descaling temperature:
[0112] (1) If the water temperature reported by the water pan temperature sensor is between 20 and 50°C, it is at the optimal descaling temperature and the unit does not need to adjust the water temperature;
[0113] (2) If the water temperature reported by the water pan temperature sensor is below 20°C, the unit will adjust and reduce the water pump flow and fan speed to reduce the heat dissipation, thereby effectively raising the water pan temperature to the optimal descaling temperature of 20-50°C;
[0114] (3) If the water temperature reported by the water pan temperature sensor is above 50°C, the unit will adjust to increase the water pump flow and fan speed to increase the heat dissipation, thereby effectively reducing the water pan temperature and making the water temperature reach the optimal descaling temperature of 20 to 50°C.
[0115] It can be understood that the start time t (min) of the automatic descaling agent delivery device can be set according to the actual descaling agent concentration, the water quality of the environment, etc., and this application does not make any specific limitation.
[0116] The present application proposes an automatic descaling and control method for an evaporative cooling external unit of a computer room air conditioner, which has the following advantages: a remote control module and necessary sensors are integrated in the evaporative cooling external unit of the computer room air conditioner, and connected to a 5G network communication module. Through a descaling prediction method based on a 5G network, it is determined when automatic descaling operation is required. The automatic descaling agent delivery device is turned on only when the water temperature reaches the optimal descaling temperature by judging and adjusting the water pump flow and fan speed through the unit. The dosage of the automatic descaling agent delivery device is set by two methods: the volume of the water tank and the circulating water flow. The automatic descaling agent delivery device can be placed in the pipeline after the water pump or in the pipeline before the water pump. The sprayed water and agent fall onto the solid bevel after passing through the heat exchanger, heat dissipation filler, water tank, etc., and gather into the scale precipitation area formed by the combination of the boss of the primary filter and the enclosure of the edge of the water tank, so as to achieve comprehensive descaling and efficient sewage discharge. Both the primary and secondary filters can be disassembled, replaced or cleaned. Automatic descaling and sewage discharge are achieved through the sewage electric ball valve and the water replenishment electric ball valve, and the water pump is guaranteed not to run without water. After the descaling is completed, the maintenance personnel will be notified, and the descaling will not be stopped during the whole process to ensure the normal operation of the unit. Feedback the descaling data to the descaling prediction model to realize model self-tuning. The status of the evaporative cooling outdoor unit of the computer room air conditioner is continuously monitored through the 5G network, and descaling operations, abnormal notifications, etc. are automatically triggered according to the real-time detection situation.
