Brief Description of the Drawings

[0016] Figure 1 It is a flow chart of the method steps of the present invention; Figure 2 It is a system block diagram of the present invention. Detailed Embodiments

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1 See also Figure 1 The present application provides a building wall heating control method based on heat load calculation, which specifically includes the following steps: Step 1: Obtain indoor parameters corresponding to the building wall, and the indoor parameters include indoor room and indoor temperature information, and obtain historical data at the same time, and analyze the heating conditions of the indoor rooms based on the historical data. The specific analysis method is as follows: Each room is labeled as i, and i = 1, 2, ..., j, where j represents the total number of rooms. With the help of intelligent sensor networks and data storage systems, historical data of each room i over a period of time (such as the past heating season or the past year) is obtained. These data cover indoor temperature, outdoor temperature, heating equipment start and stop time, personnel activity time and other information.

[0019] The historical data of room i is deeply analyzed to find out the temperature variation patterns of room i in different seasons and different types of working days (weekdays, weekends, etc.) and the corresponding heating demand patterns, so as to determine the heating period of each room. Based on these analysis results, the room heating information is generated, which includes the heating start time, end time, temperature demand preference, etc. of each room.

[0020] Get the current indoor temperature T of room i in real time i-in and outdoor temperature T out , calculate the difference between the two and compare the difference with the preset value set by the operator For example, the operator can set the preset value based on experience and indoor comfort requirements. Set to 5℃; like , indicating that the temperature difference between indoor and outdoor is large, the indoor heat loss is fast, and room i needs to be heated. At this time, the system generates a heating analysis signal. , indicating that the temperature difference between indoor and outdoor is small, the current indoor heat condition is relatively stable, and there is no need for additional heating of room i. The system generates a normal monitoring signal and continues to monitor indoor and outdoor temperature and other parameters in real time.

[0021] Step 2: Process the generated heating analysis signal, obtain the corresponding indoor room marked as the room to be adjusted for heating, and calculate its building envelope heat load and fresh air heat load. The specific calculation methods are as follows: Calculate the building envelope heat load of the room to be adjusted for heating. According to the formula Calculate the corresponding building envelope heat load Q1, where K is the building envelope heat transfer coefficient, and the specific calculation formula is , where is the indoor surface heat transfer coefficient (about ), is the outdoor surface heat transfer coefficient (about ), is the thickness of each layer of material, is the thermal conductivity of each layer of material, F is the building envelope area, specifically expressed as the area of the room wall, is the indoor-outdoor temperature difference, and ; In a specific example, the external wall area F = 10m 2 , the material is 240mm brick wall, and its corresponding thermal conductivity is , the inner surface is plastered, and the corresponding material thickness is 20mm, and its corresponding thermal conductivity is , according to the formula Calculate the building envelope heat transfer coefficient K to get , and at the same time determine that the indoor and outdoor temperatures are t 室内 = 20°C, t 室外 = -5°C, and the further temperature difference is 25°C. At the same time, according to the formula Calculate the building envelope heat load Q1 to be 420W.

[0022] Calculate the fresh air heat load of the room to be adjusted for heating. According to the formula Calculate the corresponding fresh air heat load Q2, where c is the specific heat capacity of air (about ), is the air density (about 1.2 kg / m 3 ), and L is the fresh air volume; Sum the calculated building envelope heat load Q1 and fresh air heat load Q2 to obtain the total heat load Q of the room to be adjusted for heating z , and at the same time consider the influence of solar radiation and wind speed, and correct the total heat load Q z . According to the formula Calculate the corrected total heat load , where is the solar radiation correction coefficient (taking 0.7 - 0.9 during the day for south-facing walls and 1.0 at night). is the wind speed correction coefficient (taking 1.1 - 1.2 when the wind speed > 5 m / s).

[0023] Step 3: First, use a high-precision temperature sensor to collect the indoor temperature of the room to be heated and adjusted in real time. At the same time, based on factors such as the past heating data, usage habits, and seasonal changes of this room, determine the corresponding set temperature, and combine with the overall total heat load of the building calculated in the early stage , considering factors such as the area, orientation, and insulation performance of the room, accurately calculate the heat load Q 待调 to be adjusted, and according to the formula calculate the heat load Q 待调 to be adjusted, is the difference between the set temperature and the real-time temperature, reflecting the gap between the current room temperature and the desired temperature, and t 设计 is the temperature difference parameter under the design conditions (for example, in the standard design conditions, it may be set to 10 °C, depending on the design specifications and actual situation). According to the calculated heat load Q 待调 to be adjusted, further analyze the adjustment of the supply water temperature.

[0024] Use the formula to calculate the adjusted supply water temperature , where represents the average heat transfer temperature difference of the radiator in the initial state, which reflects the average temperature difference between the radiator and the indoor environment under the current initial conditions such as the supply water temperature, and is a basic parameter of the radiator's heat dissipation capacity. K1 is the heat transfer coefficient of the radiator, and the unit is , and its value depends on factors such as the material of the radiator (such as cast iron, steel, copper-aluminum composite, etc.), the structural form (such as column type, wing type, etc.), and the surface condition, etc.

[0025] Generally speaking, for radiators with good material thermal conductivity and a structure conducive to air convection, the heat transfer coefficient will be relatively high. F1 is the heat dissipation area of the radiator, and the unit is square meters (m 2 ), and the larger the heat dissipation area, the more heat can be dissipated under the same conditions. The principle of this formula is based on the heat dissipation characteristics of the radiator. By comparing the heat load to be adjusted with the heat load calculated according to the current working conditions , combined with the heat transfer coefficient and heat dissipation area of the radiator, determine the difference in the supply water temperature that needs to be adjusted to meet the heat load requirements of the room; Obtain the real-time temperature of the current supply water in real time, and use the calculated adjusted supply water temperature as the standard to adjust the real-time temperature and generate supply water temperature adjustment information. The specific adjustment method is as follows: If , it indicates that the real-time temperature of the current water supply is lower than the regulated water supply temperature , that is, the real-time temperature of the current water supply is lower than the regulated water supply temperature , at this time, the system will generate a water supply temperature increase adjustment message, indicating that the heating control system needs to increase the water supply temperature to increase the heat dissipation of the radiator, so that the room temperature reaches the set temperature. Conversely, if , it indicates that the real-time temperature of the current water supply is higher than the regulated water supply temperature , that is, the real-time temperature of the current water supply is higher than the regulated water supply temperature , the system will generate a water supply temperature decrease adjustment message, instructing the heating control system to lower the water supply temperature to avoid energy waste caused by overheating.

[0026] In a specific example, assume that the bedroom of a certain residence is the room to be heated and adjusted. The real-time indoor temperature measured by the temperature sensor is 18 °C. According to historical data and winter heating requirements, the set temperature of this bedroom is determined to be 20 °C, and it is calculated that is 2 °C. Given the total heat load of this residence is 600 W. After comprehensively considering factors such as the proportion of the area of this bedroom in the total area of the residence, the heat load Q to be adjusted is calculated 待调 is 800 W, and the temperature difference parameter t under the design conditions 设计 is 8 °C; According to the formula , given that the heat transfer coefficient K1 of the radiator in this bedroom is , the heat dissipation area F1 = 3 m 2 , and the average heat transfer temperature difference of the radiator in the initial state is 10 °C. According to the formula the regulated water supply temperature is calculated , for example, the regulated water supply temperature obtained through calculation is 54 °C, and the real-time temperature of the current water supply is 45 °C. Since the heat load to be adjusted , it is necessary to increase the temperature, and the calculated temperature difference is 9 °C.

[0027] Step 4: Periodically monitor and process the obtained water supply temperature adjustment signal. Monitor the real-time indoor temperature at a period of T, and compare it with the real-time outdoor temperature. If the difference between the two is greater than the preset value, a heating adjustment signal is generated. Conversely, if the difference between the two is less than the preset value, a normal monitoring signal is generated. At the same time, obtain historical data and analyze the heating situation during the same period of historical data. Then, select the heating situation corresponding to the regular period to generate regular heating information.

[0028] Build a professional data storage and analysis platform to comprehensively obtain the historical heating data of the room or area, covering detailed information of the past few years or multiple heating seasons, including indoor and outdoor temperatures, supply water temperatures, start and stop times of heating equipment, energy consumption data, etc. at different time periods. Use data analysis algorithms (such as time series analysis, clustering analysis, etc.) to deeply analyze the heating conditions in the same time period of the historical data.

[0029] For example, through analysis, it is found that during the periods of 9:00 - 11:00 and 14:00 - 16:00 on weekdays every week, there is frequent indoor personnel activity and a relatively high temperature requirement. The operation of the heating system has certain rules during these periods. For example, the supply water temperature usually remains at a relatively high level and the equipment operates stably.

[0030] Based on the results of such analysis, select the time periods with obvious rules, extract corresponding heating parameters, equipment operation status and other information, and generate regular heating information. These information can be used as a reference basis for the optimized operation of the heating system, helping to make advance predictions and preparations, and improving the accuracy of heating and energy utilization efficiency.

The specific processing method is the same as the processing process in Step 4 of Embodiment 1; Heating control output unit, which is used to display the obtained water supply temperature regulation information and regular heating information to the corresponding operators.
