Technical Field
[0001] The present invention relates to the technical field of water hydrogen production, and in particular to a temperature and humidity control system and method for an indoor water hydrogen production station. Background Art
[0002] During the operation of the offshore hydrogen production station, the air conditioner and wind guide equipment are unable to reasonably control the temperature, humidity and flow rate in the space, resulting in the equipment becoming damp or overheated and unable to operate under optimal conditions.
[0003] The offshore water hydrogen production station relies on seawater as the main raw material for electrolysis, and its products are mainly hydrogen and oxygen, so the air tightness, fire prevention, and explosion prevention of the equipment are relatively strict. The hydrogen and oxygen gases generated during the operation of the hydrogen production equipment are within the explosion limit range, and the volume of hydrogen is small. If there are open flames, sparks, static electricity, and friction on site, fires and explosions are prone to occur. Therefore, the water hydrogen power plant requires strict control requirements for the temperature and humidity of the indoor space.
[0004] In addition, the electrolyte will volatilize when the water electrolyzer is working, causing the electrolyte concentration to change. Moreover, as the temperature and humidity of the external environment change, the water electrolyzer will produce condensation, affecting the normal operation of the equipment. Therefore, it is also very important to reasonably control the humidity of the indoor space. Water electrolyzers generally use seawater as raw material. Seawater has strong conductivity. If water droplets splash, it may cause safety accidents. Moreover, seawater is very easy to breed bacteria and cause water pollution. Therefore, the number of particulate matter in the air at the production site should also be controlled; at the industrial hydrogen production site, the bacterial content in the air will also have a great impact on product quality. Therefore, the bacterial content in the air needs to be controlled.
[0005] Therefore, there is an urgent need for an indoor temperature and humidity control system for water hydrogen production stations. Through the integrated temperature sensor, the spatial temperature information of each area can be fed back in real time. At the same time, the analysis results of temperature, humidity and air flow rate can simultaneously control the air conditioner, air guide equipment and external window switches to achieve precise control of the temperature, humidity and air flow rate in the space to prevent the equipment from getting damp or overheating. Complying with relevant specifications and standards and ensuring that environmental conditions meet equipment requirements are important measures to ensure the stable operation of water hydrogen production stations. Summary of the invention

[0013] In a preferred embodiment, the method for controlling the carbon dioxide content in the multiple regions includes: 1) The central controller calculates the carbon dioxide content in multiple areas through multiple carbon dioxide sensors; 2) When the carbon dioxide content in a certain area is greater than 500ppm, it means that there is excess carbon dioxide in the area; 3) When the carbon dioxide content in a certain area is greater than 500ppm, and the carbon dioxide content in other areas is less than 500ppm, it means that water leakage occurs in this area; According to the above monitoring results: 1) When the carbon dioxide content in a certain area is greater than 500ppm, the central controller controls the air conditioner to cool the area or controls the air guide equipment to ventilate the area; 2) When the carbon dioxide content in a certain area is greater than 500ppm and the carbon dioxide content in other areas is less than 500ppm, the central controller controls the alarm module to alarm.
[0014] In a preferred solution, the temperature change rate is calculated by using a multi-stage calculation method based on the temperature data obtained at each temperature point in the temperature sensor. The specific method is as follows: 1) The central controller synchronously receives the temperature information continuously sent by the temperature sensors in all areas within a certain period of time, that is, for the temperature sensors in each area, it continuously receives multiple temperature values within a certain period of time; 2) For one of the areas, the central controller calculates the temperature change rate Ft of the multiple temperature information sent by each temperature sensor; Ft=(△T2-△T1) / T1; Among them, △T1 and △T2 are two consecutive temperature differences, that is, △T1=T2-T1, △T2=T3-T2; 3) For the above-mentioned areas, the central controller calculates the average value of multiple temperature change rates Ft, and screens out the number of abnormal change rates, the maximum temperature value and the minimum temperature value; The abnormal temperature change rate exceeds a preset threshold value; 4) For the above-mentioned area, the central controller determines whether the current area is an abnormal temperature area, that is, based on the above-mentioned average temperature change rate, maximum temperature value and minimum temperature value, and the number of abnormal temperature change rates, and marks it according to the result; 5) Repeat the above steps 2)-4) until all areas are marked; 6) The central controller generates a temperature control signal according to the mark of each area and sends it to the air conditioner or air guide device.
[0015] In a preferred solution, the outer window switch comprises a slide groove arranged on the bottom plate portion of the window frame, a slider is arranged in the slide groove, and a vertical pin is arranged on the top of the slider; It also includes a connecting rod, a strip hole is provided on the connecting rod, a pin is inserted into the strip hole, a fixed hinge seat is provided on the raised portion on the inner side of the window frame, a movable hinge seat is provided on the bottom edge on the inner side of the window frame, and two ends of the connecting rod are respectively hinged on the fixed hinge seat and the movable hinge seat; A limiting groove is arranged on the inner bottom edge of the window body, and the movable hinge seat is arranged in the limiting groove.

The motor is wirelessly connected to the central controller and is remotely controlled and driven by the central controller.
[0017] The indoor temperature and humidity control system and method of a water hydrogen production station provided by the present invention has the following beneficial effects: (1) By setting temperature sensors and humidity sensors in each area, the temperature and humidity changes in each area are monitored in real time, and the temperature and humidity change rate is calculated. The central controller accurately controls the working status of the air conditioner and air guide equipment based on these data to ensure that the indoor temperature and humidity are always within the optimal range. The multi-stage calculation method enables the system to more accurately judge the temperature change trend, issue alarm signals in time and take corresponding control measures to prevent equipment from being damaged due to excessively high or low temperatures; (2) By calculating the coupling degree between the air conditioner and the window switch, the central controller can determine whether the two work together. When the coupling degree is not 0, it means that the air conditioner and the window switch work together. The system can dynamically adjust the working power of the air conditioner according to the different values of the coupling degree to improve energy utilization efficiency. When the coupling degree is greater than the preset value, the system can automatically shut down the air conditioner or adjust its working power to avoid unnecessary energy consumption and extend the service life of the equipment. (3) By setting up carbon dioxide sensors, the carbon dioxide content in each area is monitored in real time. When the carbon dioxide content in a certain area exceeds 500ppm, the central controller can promptly issue an alarm signal and control the air conditioner or air guide equipment for ventilation to prevent equipment failure or personnel health problems caused by excessive carbon dioxide. When the carbon dioxide content in a certain area exceeds 500ppm, while the carbon dioxide content in other areas is lower than 500ppm, the system can determine that there is a water leak in the area and issue an alarm signal, and take timely measures to prevent accidents; (4) Through the multi-stage calculation method, the central controller can more accurately calculate the temperature change rate of each area, and make a comprehensive judgment based on the average temperature change rate, maximum temperature value, minimum temperature value and the number of abnormal change rates, and timely mark the temperature abnormal areas. Based on these marks, the central controller generates a temperature control signal and sends it to the air conditioner or air guide equipment to achieve precise control of the temperature.

[0027] Embodiment 3: Combination Figure 3 Based on Example 1, the control method of the central controller controlling the outer window switch includes: 1) continuously collecting the switch status of the air conditioner and multiple external window switches at preset time intervals, thereby obtaining the switch status of the air conditioner and the switch status of the multiple external window switches; 2) Calculate the coupling degree between the switch states of multiple exterior window switches and the switch states of air conditioners within a set time period; The calculation formula of coupling degree C is: C = N1 + N2; Wherein, N1 is the number of times the air conditioner and multiple exterior window switches are in the on state at the same time, and N2 is the number of times the air conditioner and multiple exterior window switches are in the off state at the same time; When the coupling degree is not 0, it means that the air conditioner and the exterior window switch work in coordination; When the coupling degree is 0, it means that the air conditioner and the exterior window switch do not work in coordination; 3) By comparing the calculated coupling degree with a plurality of preset values, the operating power of the air conditioner is determined, specifically: When the coupling degree is greater than a first preset value, the air conditioner is turned off; When the coupling degree is greater than the second preset value and less than the first preset value, the air conditioner is controlled to operate at the first preset power; When the coupling degree is greater than the third preset value and less than the second preset value, the air conditioner is controlled to operate at the second preset power; When the coupling degree is less than the third preset value, the air conditioner is controlled to operate at the third preset power.
[0028] Take the three areas A, B, and C as examples. Each area has a temperature sensor, a humidity sensor, an external window with an external window switch, and an air guide device. The air conditioner is located in the fresh air system, and all devices are wirelessly connected to the central controller. This specifically explains how the central controller controls the working status of the external window switch and the air conditioner through coupling calculation: 1. Data collection; The central controller continuously collects the switch status of the air conditioner and each area's window switch at a time interval of 10 minutes. Assume that the data within one hour (6 time intervals) is as follows:
[0029] 2. Calculate the coupling degree; According to the formula: C = N1 + N2; Wherein, N1 is the number of times the air conditioner and multiple exterior window switches are in the on state at the same time, and N2 is the number of times the air conditioner and multiple exterior window switches are in the off state at the same time; Calculate the coupling degree of the three regions A, B, and C respectively: Area A: The number of times in the open state is N1 = 4 times (the 1st, 2nd, 5th, and 6th time intervals); The number of times in the off state is N2 = 2 times (the 3rd and 4th time interval); C A =4+2=6; Zone B: The number of times in the open state is N1 = 2 times (the time interval between the 2nd and 5th); The number of times in the off state is N2 = 2 times (the 3rd and 4th time interval); C B =2+2=4; Zone C: The number of times in the open state is N1 = 4 times (the 1st, 2nd, 5th, and 6th time intervals); The number of times in the off state is N2 = 2 times 2 times (the 3rd and 4th time interval); C C =4+2=6; 3. Determine the operating power of the air conditioner; Assume the following preset values: First default value: 6 Second default value: 4 Third preset value: 2 According to the comparison between the coupling degree and the preset value, the operating power of the air conditioner is determined: C A =6, turn off the air conditioner at this time to avoid the temperature control effect being reduced due to the air conditioner and the outside window being opened or closed at the same time; C B =4, the air conditioner works at the first preset power, reducing the operating power of the air conditioner as much as possible to save energy; C C =6, turn off the air conditioner at this time to avoid the temperature control effect being reduced due to the air conditioner and the outside window being opened or closed at the same time.
[0030] In this way, the central controller determines the cooperative working state of the air conditioner and the window switch through coupling calculation, and dynamically adjusts the operating power of the air conditioner according to different values of coupling, thereby achieving precise control of indoor temperature and humidity. This method not only improves energy utilization efficiency, but also ensures the stable operation of the system.
[0031] Embodiment 4: Based on Example 1, a carbon dioxide sensor is further provided in each of the multiple areas in the water hydrogen production station room. The central controller monitors the carbon dioxide content in each area through the carbon dioxide sensor and controls the operation of the air conditioner or corresponding air guide equipment according to the monitoring results.
[0032] In a preferred embodiment, the method for controlling the carbon dioxide content in the multiple regions includes: 1) The central controller calculates the carbon dioxide content in multiple areas through multiple carbon dioxide sensors; 2) When the carbon dioxide content in a certain area is greater than 500ppm, it means that there is excess carbon dioxide in the area; 3) When the carbon dioxide content in a certain area is greater than 500ppm, and the carbon dioxide content in other areas is less than 500ppm, it means that water leakage occurs in this area; According to the above monitoring results: 1) When the carbon dioxide content in a certain area is greater than 500ppm, the central controller controls the air conditioner to cool the area or controls the air guide equipment to ventilate the area; 2) When the carbon dioxide content in a certain area is greater than 500ppm and the carbon dioxide content in other areas is less than 500ppm, the central controller controls the alarm module to alarm.
[0033] Considering that seawater, which serves as the raw material for offshore hydrogen production, is a multi-component electrolyte solution, in which the main cations are alkaline earth metal ions, which can combine with carbon dioxide to form weak acid salts, forming a carbon dioxide-carbonate system in seawater. The carbon dioxide content in the system is higher than that in conventional water. In addition, during the process of hydrogen production from water, the rise in seawater temperature will also lead to a decrease in the solubility of carbon dioxide. Carbon dioxide is easily released from the raw seawater and carries heat, causing changes in the indoor temperature of the station. Therefore, when the carbon dioxide content in a certain area increases, it can be considered that a raw seawater leakage accident may have occurred in that area.
[0034] The reason why 500ppm is used as the warning threshold is that according to some air quality standards, the indoor carbon dioxide concentration should not usually exceed 1000ppm, and ideally should be kept below 500ppm. 500ppm is a more conservative threshold used for early warning to ensure good indoor air quality. When the carbon dioxide concentration exceeds 500ppm, it may cause human discomfort, such as dizziness and difficulty breathing.
[0035] The judgment of water leakage can be further combined with humidity sensors to monitor indoor humidity. If the humidity in a certain area rises and the carbon dioxide content rises to above 500ppm at the same time, there is a high probability that a water leakage accident has occurred.
[0036] Embodiment 5: Based on Example 1, the temperature change rate is calculated by using a multi-stage calculation method based on the temperature data obtained at each temperature point in the temperature sensor. The specific method is as follows: 1) The central controller synchronously receives the temperature information continuously sent by the temperature sensors in all areas within a certain period of time (e.g., 10 seconds, 30 seconds, etc.), that is, for the temperature sensors in each area, it continuously receives multiple temperature values within a certain period of time; For example, for area 1, a temperature value is received at an interval of 1 second within 20 seconds, and a total of 20 temperature values are received. At the same time, 20 temperature values are received for each area 2, 3, etc.; 2) For one of the areas, the central controller calculates the temperature change rate Ft of the multiple temperature information sent by each temperature sensor; Ft=(△T2-△T1) / T1; Among them, △T1 and △T2 are two consecutive temperature differences, for example, △T1=T2-T1, △T2=T3-T2; The temperature change rate Ft is a plurality of continuous values, such as Ft1, Ft2, Ft3, ... (the above 20 temperature values result in 18 temperature change rates); For example, the temperature is 22°C, 22.5°C, 23°C, 22.6°C, 23.9°C, 27°C...; The temperature change rates Ft1, Ft2, Ft3... are 2.3%, 2.2%, -1.7%, 5.8%, 12.9%... respectively; 3) For the above-mentioned areas, the central controller calculates the average value of multiple temperature change rates Ft, and screens out the number of abnormal change rates, the maximum temperature value and the minimum temperature value; The calculation method of the average value of Ft is a conventional method and will not be repeated here; The abnormal temperature change rate is the change rate that exceeds the preset threshold. For example, if the threshold is ±10%, the temperature change rate that is higher than 10% or lower than -10% is the abnormal temperature change rate. For example, the average value of Ft is 6%, the maximum temperature value is 27°C, the minimum temperature value is 22°C, and the number of abnormal temperature change rates is 2; 4) For the above-mentioned area, the central controller determines whether the current area is an abnormal temperature area, that is, based on the above-mentioned average temperature change rate, maximum temperature value and minimum temperature value, and the number of abnormal temperature change rates, and marks it according to the result; Specifically: a. The average value of the temperature change rate exceeds the average threshold. For example, if the average value of the temperature change rate is greater than 5% or less than -5%, or the number of abnormal temperature change rates is greater than a certain number, such as 20% of the total number, the area is marked as an abnormal temperature area; For example, Region A: If the average value of Ft is 6% and is greater than the average threshold of 5%, or if the number of abnormal temperature change rates is not greater than 20%, such as 18*20%=4, then region A is considered to be marked as a temperature abnormality region; Region B: If the average value of Ft is 3% and less than the average threshold of 5%, or if the abnormal temperature change rate is greater than 20% for 5 times, such as 18*20%=4 times, then region B is considered to be marked as a temperature abnormality region; b. In other cases, that is, the average value of the temperature change rate does not exceed the average threshold, and the number of abnormal temperature change rates is less than a certain number, then the area is marked as a normal area; c. For abnormal areas, determine whether they belong to the temperature rising area or the temperature falling area according to the average temperature change rate, the maximum temperature value and the minimum temperature value, and update the abnormal area mark; For example, if the average value of the temperature change rate in region A is higher than the average threshold, and the maximum temperature value of 27°C exceeds the upper limit of the temperature range of 26°C, then region A is marked as an abnormally high temperature region; 5) Repeat the above steps 2)-4) until all areas are marked; 6) The central controller generates a temperature control signal according to the mark of each area and sends it to the air conditioner or air guide device; Specifically: a. If the number of abnormal areas is small, less than 20% of all areas, the generated control signal only involves the work of the air guide equipment, that is, the control signal is only sent to the air guide equipment in the corresponding area and the adjacent area to perform local temperature adjustment, so as to achieve overall indoor temperature stability; b. If the number of abnormal areas is large, exceeding 20% of all areas, the generated control signal only involves the operation of the air conditioner, that is, the control signal is only sent to the air conditioners in all areas synchronously to adjust the overall indoor temperature, so that the temperature of each area can be restored to normal in a short time; For example, the operating temperature of the air conditioner is controlled to be set at the lower limit of the normal temperature range, 22°C; c. In case of a or b, if the central controller receives temperature values of all areas and they are within the normal range for a specified period of time, it will send a control signal to shut down the air guide device or air conditioner; The central controller is also configured to receive humidity information sent by each regional humidity sensor separately, perform humidity numerical analysis, and control the overall or regional humidity according to the analysis results, or issue an early warning for the area with abnormal temperature; Usually the normal range of regional humidity is preset, such as 20%-30%; Specifically: ① The central controller continuously receives humidity values sent by humidity sensors in the same area. If the humidity values are higher than a certain threshold for a certain period of time (such as 10 seconds), the air guide equipment in the area is controlled to open for ventilation to reduce the humidity in the area. ② If the humidity does not return to the normal range after a certain period of time (such as 20 minutes) after the air guide device is turned on, the central controller controls all the external windows in the room to open to achieve the effect of rapid ventilation; ③ When the humidity values of all areas received by the central controller are within the normal range, a control signal is sent to close all air guide devices and external windows.
