TECHNICAL FIELD
[0001] The present application relates to the technical field of smart city, and particularly relates to a smart city intelligent informatization construction system and method. BACKGROUND
[0002] In summer, due to high temperature, the overall temperature of urban areas is usually higher than that of surrounding suburbs. Especially in urban office buildings, air conditioning equipment will run for a long time to reduce room temperature in order to maintain a comfortable indoor environment. During the operation of the air conditioner, the indoor heat is transferred to the outdoor to achieve the cooling effect; at the same time, the air conditioner compressor and other components will also generate additional heat when working. These heat is continuously released to the outdoor environment, causing the local temperature around the building to rise significantly, thereby being not conducive to the heat dissipation and cooling of the entire urban environment.
[0003] In off-peak periods (such as late at night), the power demand in office buildings is significantly lower than the daytime operation level, which is easy to cause excess power generation capacity and waste of electric energy. In order to reduce energy waste, the existing technology usually uses the way of pumped storage: in the low valley period, the downstream water is pumped to the upstream reservoir to store using the surplus power; in the power peak period, the water is released to drive the water turbine to generate electricity, realizing the regulation and reuse of electric energy. However, this method can balance the power supply and demand, but cannot effectively improve the overall thermal environment of the urban office building.
[0004] At present, there is an urgent need for a smart city intelligent informatization construction system and method to solve how to reduce the overall temperature of the office building in the off-peak period, and to utilize the power resources in the low valley period to reduce energy waste.

[0065] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0066] A smart city intelligent information construction system 100 is proposed, the system comprising:
[0067] The water storage module includes a water tank 110, an auxiliary pipe module 111 connected to the water tank 110, and a water supply pipe module 112. The auxiliary pipe module 111 is connected to the end of the water supply pipe module 112, and the water supply pipe module 112 is laid inside the building.
[0068] Temperature acquisition module 120 is used to acquire temperature data at various locations within the building to generate first temperature data.
[0069] The temperature comparison module 121 compares the first temperature data with a temperature threshold. If the data is greater than the temperature threshold, a temperature adjustment command is generated.
[0070] The cooling module 123 executes the temperature adjustment command to control the water pipe module 112 and the auxiliary pipe module 111 to circulate water in the water tank 110, the water pipe module 112 and the auxiliary pipe module 111 to cool the building.
[0071] Please refer to Figure 5 and Figure 6 In this embodiment, during system operation, the temperature acquisition module 120 collects temperature data at various locations inside the building, generating first temperature data, and transmits this data to the temperature comparison module 121. The temperature comparison module 121 compares the first temperature data with a preset temperature threshold. When it detects that the temperature at any location is higher than the temperature threshold, it generates a temperature adjustment command and sends the command to the cooling module 123.
[0072] Upon receiving a temperature adjustment command, the cooling module 123 activates the water pump connected to the water supply pipe module 112 and the auxiliary pipe module 111, driving water from the water tank 110 into the water supply pipe module 112. As the water flows through the water supply pipe module 112 inside the building, it exchanges heat with the indoor air and the building envelope, absorbing indoor heat. The water then flows through the end connection port into the auxiliary pipe module 111 and returns to the water tank 110. Through this cycle, heat is continuously removed from the building, and the room temperature gradually decreases.
[0073] When the temperature decreases to below the temperature threshold, the temperature comparison module 121 no longer triggers the temperature adjustment command, the cooling module 123 stops water circulation, and the system enters a standby state until the next round of temperature detection results again trigger the cooling demand.
[0074] The system can be preferentially operated during the power valley period, pre-cooling through water circulation at night or during off-peak hours, reducing the air conditioning refrigeration load during the daytime peak period, and achieving stable control of the building internal temperature and efficient use of energy.
[0075] The system starts water circulation during off-peak hours to achieve night pre-cooling of the building, which not only consumes low-cost or surplus power resources, but also reduces the dependence on air conditioning compressors during the daytime peak period, thereby reducing operating costs and alleviating the load on the power grid.
[0076] The water pipe module 112 is distributed at multiple locations inside the building, and the circulating water can uniformly absorb heat from each location as it flows through the pipes, avoiding local overheating and improving the uniformity of indoor temperature distribution.
[0077] By pre-cooling at night to reduce daytime peak load, reducing the long-term full-load operation and frequent start-stop of the air conditioning compressor, reducing equipment wear and tear, prolonging the service life, and reducing maintenance frequency and cost.
[0078] The system transfers heat during the low-peak period, more evenly and stably releases building heat, reduces the instantaneous heat accumulation around the building during the day, and has a positive effect on improving the local thermal environment.
[0079] In at least one embodiment of the present application, the system further comprises:
[0080] An ambient temperature monitoring module 130 for monitoring the ambient temperature around the building to generate second temperature data.
[0081] An ambient temperature screening module 131 screens data from the second temperature data that is less than the maximum value in the first temperature data and located in the minimum value in the second temperature data to obtain difference data.
[0082] A cooling adjustment module 132 obtains pipe data information of the corresponding position of the auxiliary pipe module 111 or the water pipe module 112 according to the difference data, and generates adjusted pipe data information.
[0083] An adjustment module 133 generates an adjustment instruction according to the adjusted pipe data information, and executes the adjustment instruction to enable the pipe corresponding to the difference data to access the water pipe module 112.
[0084] Please refer to Figure 5 and Figure 6In the embodiment, the ambient temperature monitoring module 130 is arranged at several measuring points (such as different facades, roofs, shaded / ventilated places, etc.) around the building, and collects external temperature at a set period to form second temperature data (including temperature values of each measuring point and position information / number thereof).
[0085] The ambient temperature screening module 131 judges and screens the two types of data, obtains the indoor maximum temperature value from the first temperature data, and obtains the outdoor minimum temperature value from the second temperature data. When and only when the outdoor minimum temperature value is less than the indoor maximum temperature value, the temperature difference is calculated, and the difference value data is generated according to the temperature difference and the corresponding outdoor position coordinates.
[0086] After receiving the difference value data, the cooling adjustment module 132 queries the preset pipe data information (which can include auxiliary pipes / heat exchange branches, valve addresses, pump group numbers, and distribution tank ports physically corresponding to each outdoor measuring point) according to the outdoor position identifier therein, and generates adjusted pipe data information accordingly.
[0087] The adjustment module 133 generates adjustment instructions according to the adjusted pipe data information and issues them for execution, opens (or preferentially opens large) the outdoor branch valve corresponding to the difference value data, connects the pipe to the water pipe module 112, forms a preferential circuit from the indoor to the coolest outdoor point, limits the flow or closes the non-preferential branch as needed, or synchronously sets the target frequency and minimum running time of the associated pump to ensure that the effective flow is concentrated in the preferential branch.
[0088] In this way, the circulating flow direction is optimized: the sink 110, the water pipe module 112 (indoor heat absorption), the end connection, the selected auxiliary pipe branch (outdoor heat release), and the return water to the sink 110. In the subsequent sampling period, the system can repeat the above steps to realize dynamic maintenance or switching of the preferential branch; at the same time, it can cooperate with the basic hysteresis and minimum maintenance time strategy to avoid frequent jitter.
[0089] If the subsequent detection shows that the outdoor minimum temperature value ≥ the indoor maximum temperature value, the ambient temperature screening module 131 does not output the difference value data, and the adjustment module 133 no longer triggers branch switching, and the system automatically reverts to the regular circulation (or maintains the current stable working condition), ensuring that no additional energy consumption and water disturbance is generated under the condition of no benefit.
[0090] When and only when the outdoor minimum temperature value is less than the indoor maximum temperature value, the outdoor branch corresponding to the lowest outdoor temperature is always preferentially selected to access, realizing the heat exchange path with the maximum temperature difference; under the premise of constant pump power, a lower return water temperature and a faster room temperature drop speed can be obtained.
[0091] The lower temperature of the outdoor at night, the access of the coldest branch makes the pre-cooling at night more efficient, and the peak load of the air conditioner compressor can be reduced in the daytime, so as to achieve the goal of peak load shifting and energy saving and consumption reduction.
[0092] Releasing heat in the cooler and usually better ventilated outside position reduces the instantaneous heat accumulation in a single area during the daytime high temperature period, and is beneficial to alleviate the heat mass phenomenon in the building near area.
[0093] A smart city intelligent informationization construction method is proposed, which is applied to the smart city intelligent informationization construction system 100 described in any one of the above, and the method comprises:
[0094] S101, during the non-peak period, temperature data of each position in the building is acquired to generate first temperature data.
[0095] S102, the first temperature data is compared with the temperature threshold value, if greater than the temperature threshold value, a temperature regulation command is generated.
[0096] S103, according to the temperature regulation command, the water pump of the water pipeline and the water pump of the auxiliary pipeline are controlled to work, so as to circulate the water in the water tank 110, the water pipeline and the auxiliary pipeline, and to cool the building.
[0097] Please refer to Figures 1-4 In this embodiment, first, after entering the non-peak period of electricity, the system automatically starts the temperature acquisition process, collects the indoor temperature data in real time through the sensors distributed at each position of the building, and generates first temperature data by summarizing the collection results. The data can accurately reflect the thermal environment state of different areas of the building.
[0098] Then, the system compares the first temperature data with the pre-set temperature threshold value. When it is detected that there is a region in the building with a temperature higher than the threshold value, it is determined that there is a cooling demand at present, and a temperature regulation command is immediately generated. Otherwise, if the temperature of all collection points does not exceed the threshold value, the system remains standby until the next detection period to make judgment again, so as to avoid starting the cooling cycle without actual demand.
[0099] After generating the temperature regulation command, the system enters the execution phase. The control unit sends a start signal to the water pump of the water pipeline and the water pump of the auxiliary pipeline at the same time, so that a closed circulation is formed between the water tank 110, the water pipeline and the auxiliary pipeline. At the beginning of the circulation, the lower temperature water in the water tank 110 is pumped to the water pipeline module 112 laid in the building, and the water flow passes through each heat exchange area along the pipeline, exchanges heat with indoor air and envelope structure, and absorbs the excess heat in the building. The hot water enters the auxiliary pipeline module 111 at the end of the water pipeline through the communication port, and flows back to the water tank 110 through the module.
[0100] In the circulation process, the system can dynamically determine whether to continue running according to the continuously collected first temperature data. When the temperature inside the building drops to the temperature threshold value or below, the system automatically stops the work of the two-way water pump, ends the current cooling cycle, and enters the standby state, waiting for the triggering of the next low valley period. Through the closed-loop control of monitoring-judgment-execution-feedback, the system ensures that the cooling action is accurate, efficient and avoids energy waste.
[0101] The method limits the cooling process to be performed in the non-peak period of electricity, can complete the pre-cooling of the building in the period of lower electricity price or surplus of electricity supply, reduces the dependence on air conditioning main unit in the peak period, reduces the overall operating cost, and helps to realize the peak load shifting of power grid.
[0102] Only when the indoor temperature is higher than the preset threshold value, the cooling cycle is started, which avoids blind operation of the water pump and the circulation system in the case of not needing cooling, and significantly reduces invalid energy consumption.
[0103] The water pipe module 112 is laid in multiple areas inside the building, and the circulating water can uniformly absorb heat in different areas during the flow process, avoiding local overheating and improving the balance and comfort of the overall indoor temperature.
[0104] By pre-cooling at night to reduce the starting point of daytime room temperature, the method effectively reduces the long-time high-load operation and frequent start-stop of the air conditioning compressor, reduces the equipment wear rate, and prolongs the service life of the air conditioning system.
[0105] The method releases the heat inside the building slowly in the low valley period at night, which helps to reduce the instantaneous heat aggregation around the building in the daytime, and has a positive effect on improving the local microclimate and relieving the heat island effect.
[0106] In at least one embodiment of the present application, the method further comprises:
[0107] S104, if not greater than the temperature threshold value, the temperature comparison of the next cycle is performed.
[0108] Please refer to Figures 1-4 In the present embodiment, after entering the non-peak period, the system starts the temperature acquisition module 120, collects each position in the building once, and summarizes the first temperature data (such as partition maximum value / average value and other statistics).
[0109] The temperature comparison module 121 compares the first temperature data with the preset temperature threshold value:
[0110] If there is a measurement point / statistic greater than the threshold value, a temperature adjustment command is generated, and the cooling execution link is entered. If it is not greater than the threshold value, the system does not start the water pump, but enters the temperature comparison of the next cycle.
[0111] When the condition that is not greater than the threshold value is established, the system enters the next cycle according to the preset cycle parameter or event trigger (such as the next hour, the next time slot):
[0112] When the next cycle is reached, the collection of temperature data is performed again, and the threshold value comparison is repeated throughout the off-peak period, and the cycle is repeated until the demand exceeding the threshold value appears, or until the off-peak period ends. (In specific embodiments, a hysteresis and a minimum waiting time can be set to avoid frequent determination due to slight fluctuations. The above parameters are only implementation choices)
[0113] Once a cycle greater than the threshold value appears, the system starts the water pump of the water pipe and the auxiliary pipe according to the temperature regulation command, establishes the closed circulation of the water tank 110-water pipe-auxiliary pipe to implement cooling; in the operation, the temperature is periodically reviewed, and when it is reduced to the threshold value and below, the operation is stopped, and the threshold value comparison is returned to the evaluation state.
[0114] When the off-peak period ends and the threshold value exceeding condition does not occur, the system naturally exits the night (or valley) round; when the next off-peak period is entered, the cycle is repeated.
[0115] When the indoor temperature does not reach the threshold value, no water pump is started, and only the next cycle monitoring is entered, effectively avoiding invalid circulation and directly reducing night-time power consumption.
[0116] Periodic determination (which can be supplemented by hysteresis) avoids triggering start and stop due to sensor noise or transient fluctuations, reduces water impact and control jitter caused by frequent pump / valve switching.
[0117] In at least one embodiment of the present application, the specific steps of comparing the first temperature data with the temperature threshold value, and if greater than the temperature threshold value, generating a temperature regulation command further include:
[0118] S201, calculating the average value of the difference between the first temperature data and the temperature threshold value, obtaining a first cooling value.
[0119] S202, calculating the temperature value that can be cooled in the off-peak period according to the first cooling value, obtaining an expected cooling value.
[0120] S203, calculating the water pump working power of the water pipe and the auxiliary pipe according to the expected cooling value, generating power data.
[0121] S204, generating the temperature regulation command according to the power data.
[0122] Please refer to Figures 1-4In this embodiment, first, the system processes the difference between the first temperature data and the temperature threshold. Specifically, the average of the excess part is calculated from all temperature measurement points above the threshold, obtaining the first cooling value, which reflects the average temperature difference that needs to be reduced in the current building interior.
[0123] Subsequently, the system evaluates the cooling capacity that can be achieved within this time window in combination with the current non-peak power period, converts the first cooling value into the expected cooling value. This conversion takes into account the duration of the valley period, the heat exchange efficiency of the water circulation system and the operating upper limit of the equipment, so as to obtain a target temperature drop value that meets the cooling demand and is within the range that the equipment can withstand.
[0124] Next, the system calculates the working power of the water pump in the water pipeline and the auxiliary pipeline according to the expected cooling value, and generates corresponding power data. This process converts the target temperature drop into the required water flow, and then combines the characteristic curve of the water pump to obtain the optimal power setting value, ensuring that the circulating water can effectively remove indoor heat without causing energy waste or equipment overload.
[0125] Finally, the control unit generates temperature adjustment commands according to the power data and sends them to the water pipeline pump and the auxiliary pipeline pump, so that the two pumps operate at the set power to drive the formation of stable circulating water flow between the water tank 110, the water pipeline and the auxiliary pipeline. During the circulation process, the water flow continuously transfers indoor heat to outdoor or low-temperature water bodies, gradually reducing the temperature inside the building. When the system detects that the temperature has fallen to the threshold or below, it automatically stops the water pump operation, completing the current cooling task.
[0126] By calculating the first cooling value and combining the available cooling capacity during the non-peak period, the cooling amplitude is accurately matched with the actual demand.
[0127] According to the expected cooling value, the pump power is matched, unnecessary energy consumption is reduced, and the effective cooling amount corresponding to unit power consumption is maximized.
[0128] The first cooling value calculation formula is as follows:
[0129] , ;
[0130] The calculation formula of the expected cooling value is as follows:
[0131] , ;
[0132] The calculation formula of the power data is as follows:
[0133] , , , .
[0134] wherein, is the indoor measurement point temperature, is the temperature threshold, is the off-peak available duration, is the equivalent heat capacity, is the device sustainable heat exchange upper limit, is the specific heat of water, is the water density, is the supply and return water set temperature, is the head, is the pump system efficiency.
[0135] In at least one embodiment of the present application, the method further comprises:
[0136] S301, obtaining the ambient temperature around the building to generate second temperature data.
[0137] According to the second temperature data and the first temperature data, difference data is generated.
[0138] S303, according to the difference data, the pipe information corresponding to the difference data coordinate is obtained, and the adjustment pipe data information is generated.
[0139] S304, according to the adjustment pipe data information, adjustment instructions are generated, and the adjustment instructions are executed to make the pipe corresponding to the difference data access the water use pipe module 112.
[0140] Please refer to Figures 1-4 In this embodiment, first, the system continuously obtains the ambient temperature at several positions around the building to form second temperature data with spatial identification.
[0141] Subsequently, the control unit fuses and operates two types of data to generate difference data. The difference data depicts the temperature difference potential between the indoor hot end and the outdoor cold end and its spatial corresponding relationship: one common implementation is to take the difference between the maximum value in the first temperature data and the minimum value in the second temperature data, or to take the difference between each indoor sampling point and its corresponding outdoor sampling point according to the partition to obtain a set of temperature difference values with coordinates (or numbers).
[0142] Then, the system retrieves the pipe information corresponding to the coordinate of the difference data in the preset device information table, such as the corresponding auxiliary pipe / heat exchange branch, the distribution water heater port, the valve address and the associated pump group number, and generates adjustment pipe data information accordingly.
[0143] Finally, the control unit generates adjustment instructions according to the adjustment pipeline data information and executes, opens (or preferentially opens large) the outer branch valve pointed by the difference data, so that the branch is connected to the circulating path of the water pipeline module 112; if necessary, the operating parameters of the associated pump are set to ensure that the effective flow passes through the low-temperature branch to complete heat release. From this moment, the water tank 110, the water pipeline module 112 (indoor heat absorption), the end connection, the connected outdoor low-temperature branch (outdoor heat release), and the return water to the water tank 110 form a closed cycle characterized by the maximum temperature difference path. The control unit periodically reviews the indoor temperature, and if the target is reached, the adjustment is exited, and if the target is not reached, the connected branch is maintained or updated, completing the closed loop of sensing-determining-mapping-executing-reviewing.
[0144] The difference data is generated by the second temperature data and the first temperature data, and the corresponding outdoor low-temperature branch is connected according to the difference data, so that the circulating water obtains greater temperature difference driving under the same flow, the return water temperature is lower, the heat carried away in unit time is more, and the cooling is faster.
[0145] Only the branch corresponding to the difference data and having the most heat release advantage is connected, and the participation of inefficient branches is limited or avoided, the effective flow is concentrated, the pump's invalid work and unnecessary pressure drop loss of the pipeline network are reduced, and the energy efficiency is improved.
[0146] Low-temperature points are more likely to occur outdoors at night, and the low-temperature branch is preferentially connected to form the effect of night efficient pre-cooling and daytime peak shaving, thereby reducing the peak load of the air conditioning host and the energy consumption cost.
[0147] Through the path of preferentially absorbing heat at indoor hot spots and preferentially releasing heat at outdoor cold spots, the room temperature fall-back time is shortened, the partition temperature difference is reduced, and the overall comfort is improved.
[0148] In at least one embodiment of the present application, the specific steps of generating difference data according to the second temperature data and the first temperature data include:
[0149] S3021, selecting the minimum value from the second temperature data to obtain the minimum temperature value.
[0150] S3022, selecting the maximum value from the first temperature data to obtain the maximum temperature value.
[0151] S3024, calculating the difference between the minimum temperature value and the maximum temperature value to generate the difference data.
[0152] Please refer to Figures 1-4In the embodiment, the system analyzes the second temperature data outside the building, selects the lowest value from the temperature values of the plurality of external monitoring points, and determines the lowest value as the minimum temperature value. The external position corresponding to the minimum temperature value is usually the area most conducive to heat release under the current environmental conditions.
[0153] Next, the system processes the first temperature data inside the building, selects the highest value from the temperature values of the plurality of indoor collection points, and determines the highest value as the maximum temperature value. The position corresponding to the maximum temperature value is the area inside the building that most needs to be cooled at present.
[0154] After determining the minimum temperature value outside and the maximum temperature value inside, the system performs a difference operation on the two values to obtain a difference data.
[0155] By simultaneously locating the maximum temperature point inside and the minimum temperature point outside, the system can preferentially establish a heat exchange channel between the two points to maximize the heat exchange efficiency.
[0156] The difference data directly represents the maximum temperature difference that can be utilized at present, so that the water circulation system obtains a greater temperature driving force under the same flow, shortens the cooling time, and improves the cooling effect per unit energy consumption.
[0157] Preferentially cooling the hottest indoor area avoids local overcooling or uneven cooling caused by average cooling, and improves the overall comfort of the indoor area.
[0158] In at least one embodiment of the present application, the specific steps before calculating the difference between the minimum temperature value and the maximum temperature value to generate the difference data further include:
[0159] S3023, comparing the minimum temperature value and the maximum temperature value, if the minimum temperature value is less than the maximum temperature value, then calculating the difference data.
[0160] Please refer to Figures 1-4 In the embodiment, the system obtains the second temperature data around the building and the first temperature data inside the building through the environmental temperature monitoring module 130 and the temperature acquisition module 120. In the same collection period, the system selects the lowest temperature measurement point value from the second temperature data and determines the lowest temperature measurement point value as the minimum temperature value. At the same time, the system selects the highest temperature measurement point value from the first temperature data and determines the highest temperature measurement point value as the maximum temperature value.
[0161] After obtaining the minimum and maximum temperature values, the system immediately performs a comparison. If the minimum temperature value is indeed lower than the maximum temperature value, it means that there is a lower temperature environment outdoors than the indoor hot spot, which meets the conditions for heat transfer. Only then will the system proceed to the next step, calculate the temperature difference between the two, and generate the difference data.
[0162] Conversely, if the comparison results show that the minimum temperature value is not lower than the maximum temperature value, it indicates that the current outdoor temperature conditions are insufficient to effectively remove indoor heat, and may even cause reverse heat flow. To avoid invalid or unfavorable cycles, the system will skip the difference calculation step and maintain the current operating state until the next data acquisition cycle when it will make the judgment again.
[0163] By adding this effectiveness comparison step before the difference calculation, the system can ensure that subsequent heat exchange control is carried out only when there is a sufficient temperature difference, making the cooling process more accurate, efficient and safe.
[0164] The difference calculation is only initiated when the minimum outdoor temperature is indeed lower than the maximum indoor temperature, to avoid invalid loops when there is no temperature difference or the temperature difference is reversed.
[0165] During off-peak electricity hours, outdoor temperatures are more likely to be low. Effectiveness comparison can efficiently identify valuable heat exchange opportunities at night, further amplifying the pre-cooling effect.
[0166] The formula for calculating the difference data is as follows:
[0167] ,in, For difference data, This is the maximum temperature value. This represents the maximum temperature value.
[0168] In at least one embodiment of this application, the method further includes:
[0169] S305. If the minimum temperature value is not less than the maximum temperature value, then control the water pump in the water supply pipeline and the water pump in the auxiliary pipeline to work according to the temperature adjustment command.
[0170] Please refer to Figures 1-4 In this embodiment, the system simultaneously acquires first temperature data inside the building and second temperature data around the building during operation, and then filters out the maximum indoor temperature value and the minimum outdoor temperature value. Under normal circumstances, if the minimum outdoor temperature value is lower than the maximum indoor temperature value, the system will prioritize establishing a heat exchange path based on the maximum temperature difference to improve cooling efficiency.
[0171] However, at certain times, the minimum outdoor temperature may not be lower than the maximum indoor temperature, meaning that the external environment cannot provide effective cooling conditions.
[0172] When the comparison result shows that the outdoor minimum temperature value is greater than or equal to the indoor maximum temperature value, the system does not wait for the external conditions to improve, but directly starts the water pump of the water pipeline and the water pump of the auxiliary pipeline according to the generated temperature regulation command, to build a basic water circulation with the sink 110, the water pipeline and the auxiliary pipeline as a loop.
[0173] The water flow still flows in the distribution pipelines inside the building, absorbs the indoor heat and transfers it to the auxiliary pipeline and the sink 110 for buffering. Although the external cold source condition is not ideal at this time, through continuous circulation, the indoor heat can be evenly dispersed and gradually reduced to lower the room temperature, avoiding the temperature from continuing to rise due to waiting. As the circulation proceeds, the system will continuously monitor new indoor and outdoor temperature data, and once it is found that the outdoor temperature condition has turned favorable, it can be smoothly switched to the maximum temperature difference priority cooling mode, so as to maintain continuous and stable cooling effect under different environmental conditions.
[0174] Even if the external environment temperature does not have cooling advantage, the system can continuously transfer indoor heat through the basic water circulation mode to avoid temperature accumulation caused by long waiting.
[0175] When the external conditions improve, the system can seamlessly switch to the optimal heat exchange path, taking into account immediate cooling and efficient operation.
[0176] Running the basic cycle during off-peak electricity consumption time not only can take advantage of low-cost electricity, but also can cool the indoor environment in advance to provide temperature buffer for peak shaving during the day.
[0177] In at least one embodiment of the present application, the method further comprises:
[0178] S401, obtaining the wind speed of the surrounding environment of the building, and generating surrounding environment wind speed data.
[0179] S402, calculating cooling data at each place of the surrounding environment from the surrounding environment wind speed data and the second temperature data.
[0180] S403, selecting the maximum value from the cooling data to generate a cooperative cooling value.
[0181] S404, generating cooperative cooling pipeline data according to the pipeline corresponding to the cooperative cooling value.
[0182] S405, generating a cooperative cooling command according to the cooperative cooling pipeline data.
[0183] S406, executing the cooperative cooling command to connect the pipeline corresponding to the cooperative cooling pipeline data to the auxiliary pipeline or the water pipeline, and adjusting the power of the water pump of the auxiliary pipeline and the water pipeline.
[0184] Please refer to Figures 1-4 In this embodiment, the system first acquires the wind speed of the surrounding environment of the building in the same control period, generates surrounding environment wind speed data with spatial identification (synchronized in time with the aforementioned second temperature data), and ensures that the wind speed is comparable with the temperature data.
[0185] Subsequently, the control unit calculates cooling data for each measuring point outside the building in combination with the wind speed data and the second temperature data. The cooling data is essentially a quantification of the heat release capacity of the outside environment at that location: the lower the temperature and the greater the wind speed, the better the convective heat exchange conditions, and the higher the cooling data.
[0186] After completing the global calculation, the system filters the maximum value from the cooling data to obtain the synergistic cooling value and the corresponding location identification. This location is the point with the optimal outside heat release condition in the current period.
[0187] The control unit retrieves the pipe information corresponding to this location (such as the corresponding auxiliary pipe / heat exchange branch, valve address, distribution tank port, and associated pump group number, etc.) based on this, generates synergistic cooling pipe data, and further forms a synergistic cooling command: instructing the connection of the pipe of this optimal location to the circulation path of the auxiliary pipe or water pipe, and giving the power (or frequency / valve position ratio) setting value of the two-way water pump, so that the effective flow preferentially passes through the optimal branch to complete heat release. After the command is issued, the closed path of the loop is formed, with the water tank 110, the water pipe (indoor heat absorption), the terminal communication, the optimal air cooling / low temperature branch (outdoor heat release), and the return water to the water tank 110; during operation, the system periodically reviews the wind speed and temperature, and if the optimal point changes, it can smoothly switch the access branch and pump power under the premise of meeting the minimum retention time / hysteresis setting.
[0188] By incorporating wind speed and outside temperature, the actual cooling potential is calculated and used to select the route, so that the circulating water always preferentially passes through the location with the strongest convective heat exchange, resulting in lower return water temperature and faster cooling.
[0189] The surrounding environment of the building is not uniform in terms of temperature and wind due to orientation, shading, and wind channel effects. This method recalculates the cooling data periodically and selects the maximum value to dynamically lock the optimal location.
[0190] Not only is the optimal branch switched, but the power of the two-way water pump is also simultaneously set, so that the effective flow is concentrated in the most favorable heat release path; under the same power consumption, more sensible heat is removed, and the cooling output per unit of energy is higher.
[0191] During the night / low valley period, the air temperature is lower and the wind conditions are better, which can quickly form effective pre-cooling and significantly reduce the air conditioning main unit load and demand during the next day's peak period.
[0192] The calculation formula for the cooling data is:
[0193] , is the wind speed outside the location, is the temperature outside the location, is the current maximum indoor temperature value, , if dimensional scaling is required: (constant k is determined by calibration).
