Description

Technical Field

[0001] This application relates to the field of concrete temperature control technology, specifically to a method, device, and medium for concrete temperature control in high-temperature and high-humidity environments. Background Technology

[0002] With the rapid development of underground engineering projects such as tunnels, hydropower stations, and subways, the issue of temperature control and crack prevention in concrete structures during construction and service life is becoming increasingly prominent. The high-humidity underground environment is characterized by high humidity, poor ventilation, and complex temperature gradients. This leads to a coupling effect between the concrete hydration heat release rate and humidity diffusion, exacerbating the superposition effect of internal temperature and humidity stresses and significantly increasing the risk of cracking. Traditional temperature control technologies are mostly designed for surface or low-temperature environments and are ill-suited to the specific needs of high-humidity underground environments. Therefore, there is an urgent need to develop a highly adaptable, energy-efficient, and integrated temperature control method.

[0003] In related technologies, an adaptive water cooling system based on the Fuzzy-PID algorithm is employed to achieve temperature gradient control through dynamic adjustment of water temperature, water volume, and duration. Integrated modular equipment, such as ultrasonic flow meters and fiber optic temperature measuring devices, has been developed. However, this technology is mainly geared towards surface dam projects and does not consider the impact of condensation on sensor accuracy in high-humidity environments, nor does it have a mechanism for coordinated control of humidity and temperature. Another approach is the "coarse aggregate secondary air cooling + flake ice + low-temperature water mixing" process, which cools the aggregate to -1 to 3°C through an air-cooled silo and adjusts the outlet temperature to 7°C by adjusting the flake ice dosage. However, this technology relies on high-energy-consuming refrigeration equipment and is not optimized for the temperature-humidity coupling effect in underground high-humidity environments, resulting in a cooling loss rate as high as 20% to 30%. Some studies have proposed temperature control methods based on deep reinforcement learning, which predict the concrete temperature field by constructing a thermodynamic model and dynamically adjusting the heating voltage. However, these methods mostly focus on extreme low-temperature environments and do not address the interference of condensation on heating efficiency in high-humidity environments. Summary of the Invention

Detailed Implementation

[0018] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0019] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0020] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0021] Please see Figure 1 , Figure 1 This is a flowchart illustrating a concrete temperature control method for high-temperature and high-humidity environments, as shown in an exemplary embodiment of this application. (Reference) Figure 1 It can be seen that the concrete temperature control method for high temperature and high humidity environments may include: Step S110: Obtain the current temperature, current humidity, and base temperature difference of each concrete layer.

[0022] The base temperature difference represents the difference between the maximum and minimum predicted temperatures within the concrete over a preset time period. Multiple layers are defined based on the concrete depth, with corresponding concrete cooling pipes pre-embedded in each layer, and each layer corresponds to a target temperature.

[0023] In one embodiment of this application, the current temperature and humidity of the concrete at each layer, as well as the base temperature difference of the concrete, can be obtained. Based on this relevant data, the temperature field of the concrete over a predetermined time period can be predicted, and the base temperature difference can be determined based on this temperature field. It should be noted that distributed fiber optic sensors can be pre-embedded inside the concrete in a three-dimensional grid to obtain the concrete at each level, with a horizontal spacing of ≤0.5m and a vertical layering of ≤1.0m, and are sealed with a PTFE moisture-proof shell and silicone gel.

[0024] Before embedding concrete cooling pipes at each concrete level, a mixture of lauric acid (C12H24O2) and expanded graphite in a 7:3 mass ratio can be used. This mixture is heated to 85℃ to melt and bond, then cooled and shaped into 50mm×50mm×10mm blocks, which are then placed in a double-layer aluminum shell and coated with a hydrophobic nano-coating. During pipe laying, stainless steel ring pipes can be embedded inside the concrete structure, with the outer wall wrapped in an aerogel-polyethylene composite insulation layer. O-rings (fluororubber) are used for pipe connections. A refrigerant mixture of tetrafluoropropylene (R1234ze) and CO2 in a 4:1 mass ratio can be used. The screw chiller unit is turned on, and the initial refrigerant flow rate (preset flow rate) is set according to the concrete level, while simultaneously activating the residual heat recovery device. The diameter of the stainless steel ring pipes varies depending on the concrete level.

[0025] It should be noted that the concrete temperature control method for high temperature and high humidity environments provided in this application embodiment can be executed by a terminal, server, or server cluster.

[0026] Step S120: Correct the base temperature difference based on the current humidity to obtain the corrected temperature difference.

[0027] The corrected temperature difference characterizes the difference between the maximum and minimum internal temperatures of the concrete after correction.

[0028] In one embodiment of this application, the baseline temperature difference can be corrected based on the current humidity to obtain a corrected temperature difference. The baseline temperature difference is the predicted temperature difference, representing the maximum temperature difference over a future period. However, the influence of humidity on temperature is not fully reflected. Therefore, the current humidity can be used to correct the baseline temperature difference, improving the accuracy of temperature difference prediction and providing a reliable basis for modifying the refrigerant flow rate in subsequent steps.

[0029] Optionally, the base temperature difference is corrected based on the current humidity to obtain the corrected temperature difference, including: determining a temperature compensation value based on the current humidity; and determining the corrected temperature difference as the product of the base temperature difference and the temperature compensation value.

[0030] For example, the temperature compensation value can be determined based on a temperature compensation determination formula, which may include: ; in, This is the temperature compensation value. This represents the current humidity.

[0031] The corrected temperature can be expressed as , Based on the basic temperature difference.

[0032] Step S130: For each layer of concrete: compare the current temperature of the concrete with the preset target temperature; if the current temperature of the concrete is greater than the preset target temperature and the corrected temperature difference is greater than or equal to the preset temperature difference threshold, then determine the refrigerant flow rate based on the corrected temperature difference and start the dehumidification device; if the current temperature of the concrete is greater than the preset target temperature and the corrected temperature difference is less than the preset temperature difference threshold, then determine the refrigerant flow rate based on the base temperature difference.

[0033] In one embodiment of this application, for each layer of concrete: the current concrete temperature can be compared with a preset target temperature; if the current concrete temperature is greater than the preset target temperature and the corrected temperature difference is greater than or equal to a preset temperature difference threshold, the refrigerant flow rate is determined based on the corrected temperature difference, and the dehumidification device is activated; if the current concrete temperature is greater than the preset target temperature and the corrected temperature difference is less than the preset temperature difference threshold, the refrigerant flow rate is determined based on the base temperature difference. A current concrete temperature greater than the preset target temperature indicates that the concrete temperature in that layer exceeds a preset value, requiring temperature control for that layer. The refrigerant flow rate is determined based on the relationship between the corrected temperature difference and the preset temperature difference threshold, either by the corrected temperature difference or by the base temperature difference.

[0034] Optionally, the process of determining the refrigerant flow rate based on the corrected temperature difference and starting the dehumidification device in step S130 may include: determining a first flow rate increment based on the difference between the corrected temperature difference and a preset temperature difference threshold; and determining the first refrigerant flow rate as the sum of the preset flow rate and the first flow rate increment. Each layer of concrete corresponds to a preset flow rate, and each layer corresponds to a difference multiple. The first flow rate increment can be obtained by multiplying the difference between the corrected temperature difference and the preset temperature difference threshold by the difference multiple.

[0035] The first velocity increment can be expressed as: ; in, This is the first velocity increment; The difference factor can be 0.1 times the preset flow rate, or it can be set by the operator according to the actual situation. The preset temperature difference threshold can be set to 2.

[0036] The refrigerant flow rate can be expressed as: ; in, The first refrigerant flow rate, The preset flow rate.

[0037] It should be noted that in high humidity environments, the temperature difference correction is greater, and the flow rate of the first refrigerant is significantly increased. This can effectively reduce the heat dissipation caused by high humidity and prevent overheating cracks inside the concrete.

[0038] Optionally, the process of determining the refrigerant flow rate based on the baseline temperature difference in step S130 may include: determining the second flow rate increment based on the difference between the baseline temperature difference and a preset temperature difference threshold; and determining the second refrigerant flow rate as the sum of the preset flow rate and the second flow rate increment.

[0039] The second velocity increment can be expressed as: ; in, This is the second velocity increment; The difference factor can be 0.1 times the preset flow rate, or it can be set by the operator according to the actual situation. The preset temperature difference threshold can be set to 2.

[0040] The refrigerant flow rate can be expressed as: ; in, The second refrigerant flow rate, The preset flow rate.

[0041] It should be noted that in a high-humidity environment, if the corrected temperature difference does not exceed the preset temperature difference threshold, the humidity of the environment is relatively low. In this case, the flow rate can be increased only according to the basic temperature difference to avoid overcompensation and energy consumption under high humidity.

[0042] For example, the relevant data for each layer of concrete can be shown in Table 1.

[0043] Table 1. Relevant data for each grade of concrete. Optionally, the concrete temperature control method for high-temperature and high-humidity environments may further include: determining the energy efficiency ratio (EER) at the current moment based on concrete density, concrete specific heat capacity, and concrete temperature change rate in response to meeting performance evaluation conditions; if the EER at the current moment is less than a preset threshold, adjusting the ratio of tetrafluoropropylene to carbon dioxide in the refrigerant to a preset target ratio. The EER characterizes the efficiency of the cooling system. When the EER at the current moment is less than the preset threshold, the cooling system operates at low efficiency, possibly due to insufficient cooling capacity or low heat transfer efficiency. By adjusting the refrigerant ratio, these problems can be quickly corrected, avoiding energy waste caused by prolonged inefficient operation.

[0044] The formula for determining the energy efficiency ratio can include: ; ; in, For energy efficiency ratio, For effective cooling capacity, For compressor power consumption, For the power consumption of the circulating pump, For concrete density, The specific heat capacity of concrete, For the rate of change of concrete, It is a volumetric infinitesimal element.

[0045] For example, It can be used to determine the rate of concrete change from the start-up to the shutdown of the refrigeration unit.

[0046] It should be noted that the performance evaluation condition can be the time from the current time to the detection time. The performance ratio at the current moment can be preset to be determined every 6 hours. The preset target ratio can be 5:1. The preset threshold can be 3.5.

[0047] A 5:1 ratio is the only ratio that satisfies the requirements of latent heat >160kJ / kg and pressure <3.2MPa. This means that high humidity environments require high latent heat to compensate for cold losses (requirement >160kJ / kg), while underground pipelines require low critical pressure (requirement <3.2MPa). The initial ratio of tetrafluoropropylene to carbon dioxide can be 4:1. This initial ratio results in low pump power consumption and cost savings under normal operating conditions.

[0048] Optionally, if the current energy efficiency ratio is less than a preset threshold, the ratio of tetrafluoropropylene to carbon dioxide in the refrigerant is adjusted to a preset target ratio. The method for controlling the temperature of concrete in high temperature and high humidity environments may further include: after a preset time interval, determining the updated energy efficiency ratio based on the concrete density, concrete specific heat capacity, and concrete temperature change rate; if the updated energy efficiency ratio is less than a preset threshold, increasing the refrigerant flow rate.

[0049] The refrigerant flow rate can be increased by 10% based on the refrigerant flow rate determined in step S130 to obtain an updated refrigerant flow rate, and the refrigerant can be controlled with the updated refrigerant flow rate.

[0050] Optionally, the process of obtaining the basic temperature difference of concrete may include: obtaining temperature prediction data; the temperature prediction data includes aggregate moisture content, cement type, humidity corresponding to each collection time, and concrete temperature of each layer of concrete; based on the temperature prediction data and a pre-trained temperature prediction model, obtaining the temperature field inside the concrete within a preset time period; and based on the temperature field, determining the basic temperature difference of concrete.

[0051] First, a training sample set can be obtained, consisting of multiple training sample pairs. Each training sample pair can include training samples and corresponding sample labels. The training samples can include temperature prediction data, and the sample labels can include the temperature field within a preset time period. The temperature prediction model is trained with the goal of minimizing the mean squared error loss function, resulting in a trained temperature prediction model. The temperature prediction model can employ a long short-term memory network.

[0052] Steps S110 to S130 can be executed at a preset execution interval, or steps S110 to S130 can be executed again after updating the coolant flow rate based on the energy efficiency ratio and updating the training set of the temperature prediction model.

[0053] It should be noted that the device can perform a self-test every 24 hours using electrochemical impedance spectroscopy (frequency range 10). -2 ~10 5 The corrosion rate of metal parts is detected by (Hz). If the corrosion rate is ≥0.3 mm / year, 0.1%~0.3% benzotriazole (C6H5N3) corrosion inhibitor is added to the refrigerant.
