[0020] For example, please refer to the attached Figure 1 The present application provides a trough solar thermal collection and heating optimization method based on data analysis, which is applied to a trough solar thermal collection and heating optimization device based on data analysis, and specifically includes the following steps:
[0021] Step 1: Read the basic operating data of the target heating system, perform twin simulation based on the basic operating data, and build a heating twin network, wherein the target heating system is a trough solar heating system, and the basic operating data includes mirror field area, concentration efficiency, conversion efficiency, pipeline heat loss, inlet and outlet temperature thresholds, and water storage tank capacity.
[0022] Specifically, first, the basic operating data of the target heating system is read, wherein the target heating system is a trough solar heating system, which is used to provide centralized heating in rural areas. The basic operating data include the mirror field area, concentration efficiency, conversion efficiency, pipeline heat loss, inlet and outlet temperature thresholds and the capacity of the hot water storage tank. The mirror field area of the trough solar system is an important factor affecting the output power of the system; the concentration efficiency refers to the proportion of solar radiation focused on the collector; the conversion efficiency refers to the efficiency of the collector in converting solar radiation energy into thermal energy; pipeline heat loss refers to the heat loss caused by temperature differences during pipeline transmission; the inlet and outlet temperature thresholds refer to the temperature range of the collector inlet and outlet, which is used to ensure the normal operation of the system; the capacity of the hot water storage tank determines the system's ability to store and release heat.
[0023] Digital twin is a digital technology that simulates and predicts the behavior of a physical system by creating a virtual copy of it. It has many advantages such as authenticity and interoperability. Based on digital twin technology, twin simulation is performed according to the basic operating data to build a heating twin network. By building a heating twin network, the operation of the trough solar heating system can be simulated. The model can dynamically adjust parameters according to real-time data to reflect the actual operating status of the system, providing support for the prediction of solar heating capacity.
[0024] Step 2: Obtain environmental prediction values within a predetermined future window, wherein the environmental prediction values include predicted radiation intensity, predicted sunshine duration, and predicted temperature.
[0025] Specifically, a predetermined future window is configured, which is an expected time period and can be set according to actual conditions, such as the next week; then the environmental prediction value within the predetermined future window is obtained, which can be obtained through weather forecasts or climate models, wherein the environmental prediction value includes the predicted radiation intensity, predicted sunshine duration, and predicted temperature. By obtaining the environmental prediction value within the predetermined future window, a basis is provided for subsequent solar heating prediction and heating demand prediction.
[0026] Step three: clustering the predicted radiation intensity and the predicted temperature to determine a plurality of predicted radiation intensity intervals and a plurality of predicted temperature intervals.
[0027] Specifically, the predicted radiation intensity is a predicted radiation intensity sequence, including predicted radiation intensities at multiple time nodes; the predicted temperature is a predicted temperature sequence, including predicted temperatures at multiple time nodes; then the predicted radiation intensity and the predicted temperature are clustered, that is, the time nodes whose radiation intensity deviations and temperature deviations at adjacent time nodes are within a predetermined threshold are clustered into one category; multiple predicted radiation intensity intervals and multiple predicted temperature intervals are obtained, each interval contains multiple time nodes, represented by a time degree, the longer the time degree, the longer the time interval representing the interval; within the same interval, the predicted radiation intensity or predicted temperature can be regarded as the same.
[0028] Step 4: Input the multiple predicted radiation intensity intervals into the heating twin network for simulation, output multiple interval predicted heating amounts, map and compensate the multiple interval predicted heating amounts based on the multiple predicted temperature intervals, and sum them up to obtain the predicted heating amount.
[0029] Specifically, the middle value of the multiple predicted radiation intensity intervals is selected as the predicted radiation intensity mean value, multiple predicted radiation intensity means are obtained, and multiple time degrees of the multiple predicted radiation intensity intervals are obtained; then the multiple predicted radiation intensity means and the multiple time degrees are mapped and combined, and the multiple combination results are input into the heating twin network for simulation, and multiple interval predicted heating amounts are output. On the other hand, based on the multiple predicted temperature intervals, the heat loss analysis of the hot water storage tank is performed to determine multiple heat loss coefficients; further, the multiple interval predicted heating amounts are mapped and compensated according to the multiple heat loss coefficients to obtain multiple initial predicted heating amounts; then, the multiple initial predicted heating amounts are summed, and the summation result is used as the predicted heating amount.
[0030] Step 5: Taking the regional structure characteristics as constraints, retrieve and obtain multiple sample heat usage data sets, and train a heat usage predictor based on the multiple sample heat usage data sets, wherein the heat usage predictor includes a heating heat usage prediction unit, a living heat usage prediction unit, a greenhouse heat usage prediction unit, and a breeding heat usage prediction unit.
[0031] Specifically, regional structural characteristics are obtained, and the regional structural characteristics include housing characteristics, living characteristics, greenhouse characteristics and breeding characteristics; further, with the regional structural characteristics as constraints, multiple sample heat usage data sets are obtained based on big data retrieval, including heating heat usage data set, living heat usage data set, greenhouse heat usage data set and breeding heat usage data set; then, the heating heat usage data set, the living heat usage data set, the greenhouse heat usage data set and the breeding heat usage data set are used as training data, and the BP neural network is supervised and trained respectively to obtain heating heat usage prediction unit, living heat usage prediction unit, greenhouse heat usage prediction unit and breeding heat usage prediction unit; based on the heating heat usage prediction unit, the living heat usage prediction unit, the greenhouse heat usage prediction unit and the breeding heat usage prediction unit, a heat usage predictor is built in parallel.
[0032] By constructing heating heat prediction unit, living heat prediction unit, greenhouse heat prediction unit and breeding heat prediction unit based on BP neural network, the sophistication and intelligence of rural regional heating forecast analysis can be improved, thereby improving the accuracy, comprehensiveness and efficiency of regional heating demand forecast.
[0033] Step six: input the multiple predicted temperature intervals into the heating heat prediction unit, the living heat prediction unit, the greenhouse heat prediction unit and the breeding heat prediction unit respectively, and sum and output the predicted heat.
[0034] Specifically, the middle value of the multiple predicted temperature intervals is selected as the predicted temperature mean to obtain multiple predicted temperature means; multiple time degrees of the multiple predicted temperature intervals are obtained, and then the multiple predicted temperature means and the multiple time degrees are mapped and combined, and the multiple mapping combination results are respectively input into the heating heat prediction unit, the living heat prediction unit, the greenhouse heat prediction unit and the breeding heat prediction unit to obtain the heating predicted heat, the living predicted heat, the greenhouse predicted heat and the breeding predicted heat; the heating predicted heat, the living predicted heat, the greenhouse predicted heat and the breeding predicted heat are further summed to obtain the predicted heat.
[0035] Step 7: If the predicted heat consumption is greater than the predicted heat supply, auxiliary heating compensation is performed on the target area within the predetermined future window according to the heat deviation.
[0036] Specifically, when the predicted heat demand is greater than the predicted heat supply, in order to ensure that the thermal comfort and heating needs of the target area are met, the predicted heat deviation needs to be compensated. First, the predicted heat demand is subtracted from the predicted heat supply to obtain the heat deviation; further, auxiliary heating compensation is performed on the target area within the predetermined future window based on the heat deviation. For example, according to the characteristics and needs of the target area, a suitable auxiliary heating system is selected, such as a gas boiler, electric heater, etc., and the operation scheduling of the auxiliary heating system is optimized based on real-time data and predicted data to ensure that additional heat is provided when needed.
[0037] The trough solar thermal collection and heating optimization method based on data analysis is applied to a trough solar thermal collection and heating optimization device based on data analysis, which can solve the technical problems that in the existing rural centralized heating method using trough solar energy, the precision and accuracy of the analysis of solar heating and heating demand are low, resulting in poor accuracy and comprehensiveness of heating prediction and heating demand prediction, and the inability to accurately set the auxiliary heating amount, resulting in poor stability and reliability of regional heating. By simulating and modeling the target heating system, a heating twin network is constructed; the environmental prediction values within a predetermined future window are obtained, including predicted radiation intensity, predicted sunshine duration and predicted temperature, and then the predicted radiation intensity and predicted temperature are clustered to determine multiple predicted radiation intensity intervals and multiple predicted temperature intervals; then the multiple predicted radiation intensity intervals are input into the heating twin network for simulation, and multiple interval predicted heating supplies are output, and the multiple interval predicted heating supplies are mapped and compensated according to the multiple predicted temperature intervals, and the predicted heating supply is obtained by summing up; on the other hand, a heat use predictor is constructed based on a neural network, including a heating heat use predictor. The heat measurement unit, the domestic heat prediction unit, the greenhouse heat prediction unit and the breeding heat prediction unit are input into the multiple predicted temperature ranges respectively, and the predicted heat consumption is outputted by summing up; finally, if the predicted heat consumption is greater than the predicted heat supply, the heat deviation is calculated and determined, and auxiliary heating compensation is performed on the target area within the predetermined future window according to the heat deviation; the precision, accuracy and scientificity of heating forecast and heating demand forecast can be improved, thereby achieving the technical goal of accurately setting auxiliary heating supply and ensuring safe and stable heating in rural areas.
[0038] Further, multiple predicted radiation intensity intervals are determined, such as Figure 2 As shown, step three of this application includes:
[0039] Obtain a predicted radiation intensity sequence within a predetermined future window, wherein the predicted radiation intensity sequence includes predicted radiation intensities at multiple time nodes; select a first predicted radiation intensity of a first node and a second predicted radiation intensity of a second node, wherein the first node is the first node of the predicted radiation intensity sequence, and the second node is the adjacent next node of the first node; perform deviation calculation on the first predicted radiation intensity and the second predicted radiation intensity to determine a second intensity deviation, and if the second intensity deviation is less than a predetermined intensity deviation threshold, merge the second node into the first node to construct a first interval; continue to select a third predicted radiation intensity of a third node, perform deviation calculation on the first predicted radiation intensity and the third predicted radiation intensity to determine a third intensity deviation, and if the third intensity deviation is less than a predetermined intensity deviation threshold, merge the third node into the first interval; if the third intensity deviation is greater than or equal to the predetermined intensity deviation threshold, set a segmentation line at the third node, and perform iterative analysis with the third node as the starting point to obtain multiple segmentation lines; cluster multiple time nodes according to the multiple segmentation lines to determine multiple predicted radiation intensity intervals, wherein the predicted radiation intensity intervals have time degree identifiers.
[0040] Specifically, first, obtain the predicted radiation intensity sequence within the predetermined future window, wherein the predicted radiation intensity sequence includes the predicted radiation intensity at multiple time nodes; then select the first node of the predicted radiation intensity sequence as the first node, select the next node adjacent to the first node in the predicted radiation intensity sequence as the second node, and obtain the first predicted radiation intensity of the first node and the second predicted radiation intensity of the second node. Then, perform deviation calculation on the first predicted radiation intensity and the second predicted radiation intensity to determine the second intensity deviation, wherein the second intensity deviation is the absolute value of the difference between the first predicted radiation intensity and the second predicted radiation intensity; configure a predetermined intensity deviation threshold, which can be set according to actual needs. If the second intensity deviation is less than the predetermined intensity deviation threshold, the second node is merged into the first node to construct the first interval.
[0041] Continue to select the next node adjacent to the second node in the predicted radiation intensity sequence as the third node, and obtain the third predicted radiation intensity of the third node; then calculate the deviation between the first predicted radiation intensity and the third predicted radiation intensity to determine the third intensity deviation; if the third intensity deviation is less than the predetermined intensity deviation threshold, the third node is incorporated into the first interval; if the third intensity deviation is greater than or equal to the predetermined intensity deviation threshold, a dividing line is set at the third node, and iterative analysis is performed with the third node as the starting point until all time nodes of the predicted radiation intensity sequence are traversed and multiple dividing lines are obtained. Finally, multiple time nodes are clustered according to the multiple dividing lines to determine multiple predicted radiation intensity intervals, wherein the predicted radiation intensity intervals have time degree identifiers.
[0042] The method of clustering the predicted temperatures to obtain multiple predicted temperature intervals is the same as the method of obtaining multiple predicted radiation intensity intervals, which is not described in detail in this application, and the predicted temperature intervals have time degree identifiers.
[0043] Further, based on the multiple predicted temperature intervals, the multiple interval predicted heating amounts are mapped and compensated, and step 4 of the present application includes:
[0044] Acquire the attribute characteristics of a heat storage tank, wherein the attribute characteristics of the heat storage tank include the material, size and structure of the water tank; retrieve and acquire a water tank sample data set with the capacity, material, size and structure of the heat storage tank as constraints, wherein the water tank sample data set includes a sample external temperature set and a sample heat loss coefficient set; construct a heat loss analysis channel based on the sample external temperature set and the sample heat loss coefficient set based on a random decision forest; select the middle value of the temperature of the multiple predicted temperature intervals as the predicted temperature mean to obtain multiple predicted temperature means; analyze the multiple predicted temperature means through the heat loss analysis channel to determine multiple heat loss coefficients; time-align the multiple heat loss coefficients with the multiple interval predicted heat supplies to determine multiple aligned heat loss coefficients, wherein the aligned heat loss coefficients correspond to the interval predicted heat supplies one by one, and if the interval predicted heat supplies include multiple mapped heat loss coefficients, the aligned heat loss coefficient is the mean of the multiple mapped heat loss coefficients; map and compensate the multiple interval predicted heat supplies according to the multiple aligned heat loss coefficients to obtain multiple interval predicted heat supplies.
[0045] Specifically, first, the attribute characteristics of the hot water storage tank are obtained, wherein the attribute characteristics of the hot water storage tank include the material, size and structure of the water tank; then, the capacity, material, size and structure of the hot water storage tank are used as retrieval constraints, and homologous information retrieval is performed based on big data technology to obtain a water tank sample data set, wherein the water tank sample data set includes a sample external temperature set and a sample heat loss coefficient set, and the sample external temperature and the sample heat loss coefficient correspond one to one, and the heat loss coefficient represents the degree of heat loss of the hot water storage tank at different external temperatures. The larger the heat loss coefficient, the higher the degree of heat loss.
[0046] Random decision forest is an integrated learning method, which improves the prediction accuracy and robustness of the model by constructing multiple decision trees and combining their prediction results; then, a heat loss analysis channel is constructed based on the random decision forest, and the heat loss analysis channel is trained using the sample external temperature set and the sample heat loss coefficient set. During the training process, the performance of the model can be evaluated by cross-validation and other techniques; according to the results of the model evaluation, the model parameters, such as the number of trees, the maximum depth, etc., are adjusted to obtain a heat loss analysis channel that meets the expected requirements.
[0047] Then, the middle temperature value of the multiple predicted temperature intervals is selected as the predicted temperature mean to obtain multiple predicted temperature means; and the multiple predicted temperature means are analyzed through the heat loss analysis channel to determine multiple heat loss coefficients; then the multiple heat loss coefficients are time-aligned with the multiple interval predicted heat supplies, and multiple aligned heat loss coefficients are determined based on the time alignment results, wherein the aligned heat loss coefficients correspond one-to-one to the interval predicted heat supply, and if the interval predicted heat supply contains multiple mapped heat loss coefficients, the aligned heat loss coefficient is the mean of the multiple mapped heat loss coefficients.
[0048] Finally, the multiple interval predicted heating supplies are mapped and compensated according to the multiple aligned heat loss coefficients, that is, the influence of the heat loss coefficient on the performance of the hot water storage tank is considered, and the predicted heating supply is compensated and adjusted. The purpose of the compensation adjustment is to ensure that the predicted heating supply more accurately reflects the actual performance of the hot water storage tank, and to obtain multiple interval predicted heating supplies.
[0049] Further, to obtain the predicted heating amount, step 4 of this application includes:
[0050] Query the historical heating records of the target heating system to obtain multiple historical heating prediction values and multiple historical actual heating values; calculate multiple prediction errors based on the multiple historical heating prediction values and multiple historical actual heating values, wherein the prediction error is the absolute value of the difference between the historical heating prediction value and the historical actual heating value; calculate the mean of the multiple prediction errors, perform difference operations on the multiple prediction errors according to the prediction error mean, and determine multiple error deviations; select the prediction errors corresponding to the error deviations less than a predetermined error threshold, obtain multiple standard prediction errors, and calculate the standard prediction error mean; sum the multiple interval predicted heating values to obtain an initial predicted heating value, attenuate the initial predicted heating value according to the standard prediction error mean, and output the predicted heating value.
[0051] Specifically, query the historical heating records of the target heating system to obtain multiple historical heating prediction values and multiple historical actual heating values; then calculate the prediction error based on the multiple historical heating prediction values and multiple historical actual heating values to obtain multiple prediction errors, wherein the prediction error is the absolute value of the difference between the historical heating prediction value and the historical actual heating value; further calculate the mean of the multiple prediction errors, perform difference calculation on the multiple prediction errors according to the prediction error mean, and determine multiple error deviations. Then, judge the multiple error deviations according to the predetermined error threshold, select the prediction error corresponding to the error deviation less than the predetermined error threshold, obtain multiple standard prediction errors, and calculate the standard prediction error mean; through the above operation, the interference of individual abnormal data can be reduced, and the accuracy and reliability of the standard prediction error mean setting can be improved.
[0052] Then, the predicted heat supply of the multiple intervals is summed to obtain the initial predicted heat supply; finally, the initial predicted heat supply is attenuated according to the standard prediction error mean to obtain the predicted heat supply, that is, the initial predicted heat supply is subtracted from the error ratio, for example, if the standard prediction error mean is 2% and the initial predicted heat supply is 1000, then the predicted heat supply is 1000×(100%-2%), that is, 980. By attenuating the initial predicted heat supply according to the standard prediction error mean, the accuracy and rationality of the predicted heat supply can be further improved to ensure the stability of regional heating.
[0053] Further, to construct a heat usage predictor, step five of this application includes:
[0054] Acquire regional structural features, wherein the regional structural features include housing features, living features, greenhouse features, and breeding features; take the housing features, living features, greenhouse features, and breeding features as constraints, perform positive sample retrieval based on big data, and determine a heating heat data set, a living heat data set, a greenhouse heat data set, and a breeding heat data set; perform supervised training and cross-validation on a BP neural network based on the heating heat data set, the living heat data set, the greenhouse heat data set, and the breeding heat data set, respectively, to obtain a heating heat prediction unit, a living heat prediction unit, a greenhouse heat prediction unit, and a breeding heat prediction unit; construct the heat prediction unit based on the heating heat prediction unit, the living heat prediction unit, the greenhouse heat prediction unit, and the breeding heat prediction unit.
[0055] Specifically, the regional structural features are obtained, wherein the regional structural features include housing features, living features, greenhouse features and breeding features, such as housing type, housing area, housing structure, greenhouse area, greenhouse type, etc. Then, the housing features, living features, greenhouse features and breeding features are used as constraints, and positive sample retrieval is performed based on big data. Positive sample retrieval is a method for retrieving samples with certain specific attributes or characteristics in a specific application scenario, that is, the homologous data is retrieved to obtain the heating heat data set, the living heat data set, the greenhouse heat data set and the breeding heat data set. Then, the BP neural network is supervised and cross-validated based on the heating heat data set, the living heat data set, the greenhouse heat data set and the breeding heat data set, respectively, to obtain the heating heat prediction unit, the living heat prediction unit, the greenhouse heat prediction unit and the breeding heat prediction unit. Finally, the heat prediction unit is constructed based on the heating heat prediction unit, the living heat prediction unit, the greenhouse heat prediction unit and the breeding heat prediction unit.
[0056] Furthermore, the present application also includes the following steps:
[0057] Acquire house structure characteristics, family population, crop type characteristics and livestock species characteristics, wherein the house structure characteristics at least include house type and house area, the crop type characteristics at least include crop type and growth cycle, and the livestock species characteristics at least include animal type and growth stage; subdivide the heating heat data set, the domestic heat data set, the greenhouse heat data set and the livestock heat data set according to the house structure characteristics, the family population, the crop type characteristics and the livestock species characteristics, and determine multiple heating heat data subsets, multiple domestic heat data subsets, multiple greenhouse heat data subsets and multiple livestock heat data subsets; use the multiple heating heat data subsets, multiple domestic heat data subsets, multiple greenhouse heat data subsets and multiple livestock heat data subsets to perform supervised training and cross-validation on the BP neural network to generate the heating heat prediction unit, the domestic heat prediction unit, the greenhouse heat prediction unit and the livestock heat prediction unit.

[0059] Then, the heating heat data set, the living heat data set, the greenhouse heat data set, and the breeding heat data set are subdivided according to the house structure characteristics, the number of family members, the crop type characteristics, and the breeding type characteristics. For example, the heating heat data with the same house type and the house area within the same threshold are grouped into one category, and multiple heating heat data subsets, multiple living heat data subsets, multiple greenhouse heat data subsets, and multiple breeding heat data subsets are determined.

[0060] Furthermore, the present application also includes the following steps:
[0061] Acquire a first house structure feature, wherein the first house structure feature includes a first house type and a first house area threshold; acquire a first heating heat data subset of the first house structure feature, wherein the first heating heat data subset includes a first sample temperature set and a first sample heat consumption set; divide the first heating heat data subset into N equal parts, and select with replacement N times to obtain a first training set, iterate and select N times to generate N training sets; take the first sample temperature as input, take the first sample heat consumption as supervision, use N training sets to perform supervised training and cross-validation on the BP neural network, obtain N first heating heat prediction branches that meet convergence, and construct a first heating heat prediction unit based on the N first heating heat prediction branches, wherein the output of the first heating heat prediction unit is the mode of the output results of the N first heating heat prediction branches; construct the heating heat prediction unit based on a decision tree according to a mapping relationship between the first house structure feature and the first heating heat prediction unit.
[0062] Specifically, this application introduces a method for constructing a heating heat prediction unit, wherein the construction methods of a living heat prediction unit, a greenhouse heat prediction unit and a breeding heat prediction unit are consistent with the construction method of the heating heat prediction unit and are not expanded in this application.
[0063] First, obtain the first house structure feature, wherein the first house structure feature includes the first house type and the first house area threshold; then obtain the first heating heat data subset of the first house structure feature, wherein the first heating heat data subset includes the first sample temperature set and the first sample heat set; further divide the first heating heat data subset into N parts, and select N times with replacement from the N data sets to obtain the first training set, and iterate and select N times to generate N training sets. Then, take the first sample temperature as input, take the first sample heat as supervision, and use the N training sets to supervise the BP neural network. The supervised training can be performed by the back propagation algorithm. After meeting the predetermined number of training times; exchange the N training sets, and after the exchange, verify the BP neural network with the N training sets to obtain N first heating heat prediction branches that meet the expected convergence conditions; finally, construct the first heating heat prediction unit based on the N first heating heat prediction branches, wherein the output of the first heating heat prediction unit is the mode of the output results of the N first heating heat prediction branches. By constructing the first heating heat prediction unit based on N first heating heat prediction branches, the prediction error of a single model can be reduced and the accuracy and reliability of the overall prediction can be improved.
[0064] Using the same method of constructing the first heating heat prediction unit, multiple heating heat prediction units of multiple house structure characteristics are obtained in turn; further based on the decision tree principle, the heating heat prediction unit is constructed with the house structure characteristics as the child node and the heating heat prediction unit as the leaf node of the child node.
[0065] Further, auxiliary heating compensation is performed, and step seven of this application includes:
[0066] With the purpose of meeting the expected heat storage performance, the soil is screened and pretreated to determine the suitable heat storage soil; based on the expected heat storage demand, a greenhouse heat release unit is built according to the predetermined heat release equipment and the suitable heat storage soil; using the target heating system, the greenhouse heat release unit stores heat during the day, and slowly releases heat from the greenhouse through the greenhouse heat release unit at night.
[0067] Specifically, first of all, the soil is screened and pretreated for the purpose of meeting the expected heat storage performance. For example, the appropriate soil type, such as sandy loam, clay, etc., is selected to ensure that the soil has good heat storage performance. At the same time, the soil is treated, such as removing impurities, adjusting the pH value, etc., to improve the heat storage effect of the soil. Then, based on the expected heat storage demand, the heat storage capacity, temperature range and thermal conductivity of the soil are considered to select the appropriate size and shape. On the other hand, suitable heat release equipment is selected, such as floor heating pipes, radiators, etc., to achieve heat release to the greenhouse. At the same time, the heat release equipment should have good thermal conductivity and corrosion resistance to adapt to the soil environment. The heat release equipment is further buried in the soil heat storage body to ensure that the equipment is in full contact with the soil to achieve effective heat transfer and build a greenhouse heat release unit.
[0068] Finally, the target heating system is used to store heat in the greenhouse heat release unit during the day, that is, the target heating system collects solar radiation energy during the day and converts it into thermal energy, which is transferred to the greenhouse heat release unit through the heat exchange system. The greenhouse heat release unit stores the collected heat in the soil. As a huge heat capacity, the soil can absorb and store a large amount of heat. At night or when solar radiation is insufficient, the soil heat storage body begins to slowly release the stored heat, that is, the heat release unit (such as floor heating pipes or radiators) absorbs heat from the soil and transfers it to the inside of the greenhouse.
[0069] Through the above steps, the heat can be stored in the greenhouse heat release unit during the day, and the heat can be slowly released from the greenhouse at night. This method can effectively reduce energy waste, improve the nighttime heating effect of the greenhouse, and promote the growth and yield of crops. At the same time, it can be adjusted and optimized according to actual needs and heating effects to meet the heating needs in different scenarios.
