[0026] Embodiment 2

[0027] This embodiment discloses an air conditioning variable air volume control method based on laboratory environment monitoring, as Figure 2 shown, and specifically includes the following: The temperature and humidity in the laboratory need to be maintained within a certain standard range. However, due to the external environment, such as seasonal temperature changes, the environmental parameters in the laboratory will be affected to a certain extent. In addition, in the process of controlling the temperature and humidity of the laboratory in the existing technology, a fixed set value is often used. This approach is prone to control lag and energy waste when facing external environmental changes. Moreover, the existing technology usually adopts a unified air-conditioning power and cannot be flexibly adjusted according to the actual number of people in the laboratory and the partition environmental parameters, resulting in difficulty in maintaining the environmental parameters within the standard range; Based on this, the following steps are provided in this embodiment: First, it is necessary to determine the total air-conditioning power required to maintain the standard environmental parameters in the current laboratory under the influence of the current external environment and when the current laboratory is unoccupied, as well as the air volume required for each air-conditioning variable air volume valve; The actual floor area of the laboratory can be obtained through the relevant data when the laboratory is built, denoted as the laboratory area S. Then, the laboratory area S is partitioned, and the area size preset by the operator is extracted , and the laboratory area S is partitioned. The partitioning operation requires the operator to partition according to the actual situation. Each partition area does not affect each other, and each partition area is equipped with corresponding sensors, namely temperature sensors and humidity sensors.

[0028] After the partitioning operation, the laboratory area S is evenly divided into j equal parts, from the first partition area to the last partition area are successively denoted as: , where is any one of the j partition areas, and both i and j are counting indices, starting from 1, and i does not exceed j.

[0029] Obtain the standard temperature calibrated by the operator for the corresponding laboratory, denoted as , and the standard humidity, denoted as ; Then, any partition area in the laboratory is processed, and the processing methods of other partition areas are the same as those of the partition area ; Determine the current temperature and humidity of the partition area , and are respectively denoted as: , ; Obtain the initial air supply volume of the air conditioner equipped in the laboratory preset by the operator. The initial air supply volume is regulated by the air-conditioning variable air volume valve in each partition area. The initial air supply volume Its value is set by the operator according to the requirements of different laboratories; Then obtain the initial air supply volume preset by the operator Its value is set by the operator according to the requirements of different laboratories; Then obtain the initial air supply volume preset by the operator ; For the partitioned area , first calculate the heat load within this partitioned area , and the calculation formula is as follows: Calculate the heat load corresponding to the partitioned area , and the heat load represents the heat quantity reduced or increased in the current partitioned area ; Among them, is the specific heat capacity of air, is the air density, and both the specific heat capacity of air and the air density are existing data and are regarded as known values in this solution; According to the formula: Calculate the moisture load corresponding to the partitioned area , and the moisture load is the amount of moisture that needs to be removed or added to adjust the humidity level within the partitioned area ; Then adopt temperature drive to calculate the minimum air volume required when regulating the current temperature and making it reach the standard temperature in the corresponding partitioned area , and the calculation formula is as follows: Among them, , indicating that the temperature in the current partitioned area is not equal to the standard temperature is a hard requirement for the formula to hold and perform calculations. If it is equal, it means that the temperature in the current partitioned area is in line with the standard temperature and there is no need to adjust the air volume of the air conditioner; Then adopt humidity drive to calculate the minimum air volume required when regulating the current humidity and making it reach the standard humidity in the corresponding partitioned area , and the calculation formula is as follows: Among them, , indicating that the current partitioned area ; Among them, , indicating that the current partitioned area The humidity inside is not equal to the standard humidity, which is a hard requirement for the formula to hold and perform calculations. If it is equal, it means that the humidity inside the current partition area matches the standard humidity, and there is no need to adjust the air volume of the air conditioner; Based on the minimum air volume determined after the above calculations and the minimum air volume , take the maximum value of the two and use it as the final minimum air volume, denoted as , to ensure that both the temperature requirement and the humidity requirement can be met; According to the methods and steps described above, process the j partition areas divided in the corresponding laboratory, and finally obtain the final minimum air volume corresponding to the j partition areas, and denote them in sequence as ; Based on the final minimum air volume corresponding to each of the j partition areas determined after the above steps: , adjust the variable air volume valves of the air conditioners corresponding to each partition area to serve as the air volume of the air conditioner for the partition area , and perform the air supply operation.

[0030] Then, according to the electric energy consumed for adjusting the temperature and humidity in the j partition areas and the energy consumption ratio of the air conditioners equipped in the corresponding laboratory, calculate the total power required to adjust the temperature and humidity of each partition area to the standard temperature and humidity, and use it as the minimum power under the current external environment of the laboratory, denoted as .

[0031] Since relevant experimental operations need to be carried out in the laboratory, heat will inevitably be generated by the human body, equipment, and chemical reactions. Therefore, it is necessary to keep the environmental parameters in the laboratory within a certain range to ensure that the accuracy of the researchers during the experiment is not affected too much; Then obtain the maximum power of the air conditioner equipped in this laboratory, and denote it as , and the maximum power is a fixed value, that is, the theoretically maximum power of the air conditioner equipped in this laboratory. Then, combined with the minimum power of the air conditioner to maintain this laboratory in a standard state under the current external environment determined by the above calculation steps , form the power adjustment range of the air conditioner; Adopt to calculate the adjustable power of the air conditioner equipped in this laboratory , which means that when adjusting the power of the air conditioner equipped in this laboratory, the highest upper limit is , the lowest lower limit is , and the span of the adjustable power is ; Then, through the counter in the access control device, the total number q of researchers in the laboratory at the current time is obtained in real time. Then, the maximum total number of researchers that the laboratory can accommodate during normal research work is obtained and denoted as Q. And let the maximum total number of researchers Q correspond to the maximum power of the air conditioner equipped in the laboratory, indicating that when the total number of researchers in the laboratory reaches the maximum total number of researchers Q, the air conditioner needs to be adjusted to the maximum power; Then, use to calculate the proportion of the total number of researchers in the laboratory at the current time compared to the maximum total number of researchers Q , and then combine the determined span of the adjustable power , and use to calculate the power of the air conditioner that needs to be adjusted corresponding to the total number of researchers in the laboratory at the current time , and then add the power to be adjusted and the minimum power to perform a summation operation to obtain the total power of the air conditioner equipped in the laboratory corresponding to the total number of researchers in the laboratory at the current time, and denote it as .

[0032] Adjust the total air conditioner power to the total power corresponding to the total number of researchers in the laboratory at the current time , and obtain the time interval t preset by the operator, and extract the temperature sensors and humidity sensors in the partition area within the area, and record the temperature collected in the partition area as , and the humidity as ; And compare the collected temperature and humidity with the standard temperature and standard humidity preset by the operator respectively, and perform a preliminary comparison operation, and use to calculate the difference rate between the temperature and the standard temperature ; and use to calculate the difference rate between the humidity and the standard humidity ; Based on the determined difference rates and difference rate , further extract the difference rate threshold preset by the operator, and compare the difference rate and difference rate with the difference rate threshold ; If the difference rate and difference rate , all through comparison, that is, the difference rate and the difference rate do not exceed the difference rate threshold preset by the operator , then it is considered that the environmental parameters (temperature and humidity) in the current partition area are less different from the standard environmental parameters, and it is determined that the environmental parameters in the current partition area are in a normal state without any processing; If the difference rate and the difference rate any one of the difference rates exceeds the difference rate threshold , then it is considered that the environmental parameters (temperature and humidity) in the current partition area are quite different from the standard environmental parameters, and it is determined that the environmental parameters in the current partition area are in an abnormal state; Using the above temperature-driven and humidity-driven calculation methods, combined with the temperature at the current time in this partition area and humidity for processing, the minimum air volume when the temperature reaches the standard temperature is obtained and denoted as and humidity the minimum air volume when reaching the standard humidity is obtained and denoted as ; Then take the maximum value of the minimum air volume and the minimum air volume and denote it as , and by adjusting the variable air volume valve of the air conditioner in this partition area, use as the air volume of the air conditioner in this partition area and conduct air supply processing.

[0033] For other partition areas, use the same method as the processed partition area and update the operation every preset time period t to re-regulate the air volume of the air conditioner.

[0034] This embodiment solves the problem that the laboratory environment is affected by external changes through partition processing, real-time monitoring and dynamic adjustment of the air volume and power of the air conditioner; its core purpose is to ensure that the temperature and humidity in the laboratory are always maintained within the standard range under the condition of changes in the external environment and the number of personnel, while optimizing energy use and reducing waste; and by flexibly adjusting the power and air volume of the air conditioner, efficient and energy-saving environmental control is achieved, providing stable and accurate experimental conditions for the laboratory.
