Background Art

[0002] As energy issues become increasingly prominent and environmental protection needs continue to increase, energy-saving optimization of air-conditioning systems has become a global focus. Existing air-conditioning equipment usually adopts a fixed operating mode and cannot fully utilize the potential energy saving opportunities brought about by ambient temperature changes. Especially in areas with large temperature differences between day and night or obvious seasonal changes, the air-conditioning system does not respond well to temperature changes, which may lead to excessive energy consumption or reduced comfort.

[0003] Traditional air conditioning system thermal parameter analysis mostly relies on static tests under laboratory conditions, which is difficult to truly reflect the dynamic changes in the heat transfer performance of air conditioning systems under complex environmental conditions. In addition, although air conditioning systems can accumulate and release heat during operation, they have not been treated as a dispatchable energy storage resource in the past, and a complete virtual energy storage management and charging and discharging power control mechanism has not been formed.

[0004] However, with the development of integrated energy interactive terminal technology, air conditioning systems can now achieve closer integration and interaction with other energy forms such as smart grids, solar power generation, wind power, etc. This terminal can monitor and respond to changes in grid load in real time, and achieve efficient use of energy and energy conservation and emission reduction through intelligent scheduling and optimized control. For example, when the grid load is low, the air conditioning system can increase its cooling capacity and store cold energy; when the grid load is peak, it can reduce the cooling capacity and release the stored cold energy, thereby achieving load balancing and optimal energy allocation.

[0036] Compared with the prior art, the beneficial effects of the present invention include at least:

[0037] The present invention is based on an integrated energy interactive terminal, which can accurately obtain key thermal parameters such as thermal conductivity and thermal mass of the air-conditioning system in the actual operating environment, and on this basis constructs a virtual energy storage capacity and charging and discharging power model of the air-conditioning system, combines the air-conditioning working mode with the energy storage concept, and interacts with the integrated energy system.

[0043] Figure 1 The present invention is a flow chart of the method for dynamic thermal parameter measurement and energy storage control of an air-conditioning system based on a comprehensive energy interactive terminal. DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only embodiments of a part of the present invention, rather than all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present invention.

[0045] Embodiment 1 of the present invention provides a method for dynamically measuring thermal parameters of air conditioners and regulating virtual energy storage under a comprehensive energy interactive terminal, which involves a dynamic measurement technology for thermal parameters of air conditioners and a virtual energy storage regulation technology for air conditioners. Figure 1 As shown, the following steps are included:

[0046] Step 1: The integrated energy interactive terminal monitors the indoor and outdoor temperatures and air conditioning power after the air conditioner is started, and uses the monitoring data when the indoor temperature change rate is zero to determine the thermal conductivity G;

[0047] Further preferably, the indoor temperature of the air-conditioning system is set to change with time to satisfy the first-order ordinary differential equation:

[0048]

[0049] Ton(t), Toff(t) are the indoor temperatures when the air conditioner is turned on and off at time t, in °C;

[0050] Tout is the outdoor temperature in °C;

[0051] Tin is the outdoor temperature in °C;

[0052] C is thermal mass, which indicates the responsiveness of the air conditioning system to temperature changes, and its unit is (kW·h) / ℃;

[0053] G is thermal conductivity, which indicates the ability of the air conditioning system to transfer heat under unit temperature difference, and the unit is kW / ℃;

[0054] s(t) is the working state of the air conditioner at time t, which is 1 when closed and 0 when open. In fact, the air conditioner works in a temperature range with a width of Tdb. When the boundary is reached, the working state of the air conditioner will be reversed.

[0055] P represents the power of the air conditioner, in kW.

[0056] After the air conditioner is started, the indoor and outdoor temperatures and air conditioning power are monitored in real time using the integrated energy interactive terminal. In the stable stage where the indoor temperature change rate is zero, the thermal conductivity G of the air conditioning system is calculated.

[0057] In the specific implementation, the time when the indoor and outdoor temperatures are relatively stable after the air conditioner is started (for example, within one hour), the indoor temperature change rate is zero (ie, dT / dt = 0), and G(T out (t)-T in (t))-P=0, and then we get:

[0058]

[0059] At this time, the indoor temperature T can be measured in real time through the integrated energy interactive terminal in (t), outdoor temperature T out After repeated experiments (e.g., 100 times) and averaging the key parameters such as the operating power P of the air conditioner, the thermal conductivity G of the air conditioning system is calculated. The accuracy of the data is ensured by high-precision sensors and stable power meters.

[0060] Within 1 hour after the air conditioner is started, the indoor temperature is stable at 25°C, the outdoor temperature is 30°C, and the air conditioner power is 2kW. Through measurement and calculation, the thermal conductivity G = 0.4kW / °C is obtained.

[0061] In order to obtain more accurate data, multiple measurements (for example, 100 times) are performed under different ambient temperatures and usage conditions, and then the average value is taken to obtain the accurate value of G.

[0062] The experiment was repeated 100 times under different ambient temperatures and usage conditions, and the average value of G was 0.4kW / ℃. In the experiment, the indoor temperature can be regarded as a fixed reference condition, while the outdoor temperature and air conditioning power are controlled and adjusted as variables to simulate different environmental changes.

[0063] Step 2: The integrated energy interactive terminal records the indoor and outdoor temperatures after the air conditioner is turned off, and determines the thermal mass C based on the thermal conductivity G and the recorded indoor and outdoor temperatures;

[0064] Further preferably, at the moment when the air conditioner switch state is switched, the thermal mass C is calculated by temperature data collected by the integrated energy interactive terminal in combination with mathematical analysis or numerical solution.

[0065] In specific implementation, when the air conditioner is just turned off (t=0) and after being turned off for a period of time, the value of the thermal mass C is calculated based on the measured indoor and outdoor temperatures at that time in combination with the ordinary differential equation.

[0066] Specifically, after the air conditioner is turned off (i.e., when s(t) = 0 and P = 0), the indoor and outdoor temperature difference will drive the indoor temperature to change. The integrated energy interactive terminal records this change and solves the ordinary differential equation to estimate the thermal mass C.

[0067]

[0068] Solving this ordinary differential equation yields,

[0069]

[0070] When t = 0,

[0071] It can be understood that in the above equation It means that the sign needs to be selected according to the actual direction of the temperature difference, and finally only a reasonable value is obtained.

[0072] By measuring the indoor and outdoor temperatures when the air conditioner is just turned off, the C 0 For example, when the air conditioner is turned off, the indoor and outdoor temperatures are 25℃ and 30℃ respectively. The C 0 The value is 1.6 (kW·h) / ℃.

[0073] After a certain period of time, the indoor and outdoor temperatures are measured again and the calculated C 0 , the value of C can be calculated; for example, after one hour, the indoor and outdoor temperatures are measured again, which are 26℃ and 29℃ respectively. Combined with the known C 0 value, calculate C, and obtain C = 0.86 (kW·h) / ℃.

[0074] In order to obtain more accurate data, multiple measurements (e.g., 100 times) are performed under different ambient temperatures and usage conditions, and then the average value is taken to obtain the accurate value of C.

[0075] The experiment was repeated 100 times under different ambient temperatures and usage conditions, and the average value of C was 0.8 (kW·h) / ℃.

[0076] When conducting the dynamic measurement of thermal parameters of the above air conditioning system, in order to ensure the accuracy and reliability of repeated experimental data, the following measures are taken:

[0077] Standardized experimental environment: All experiments are carried out under the same environmental conditions to eliminate the interference of irrelevant variables and ensure that the indoor and outdoor temperatures and air conditioning operating power data measured each time are comparable.

[0078] Precision instruments: Use high-precision and stable temperature sensors and power meters for real-time monitoring to ensure the accuracy of data sources.

[0079] A large number of repeated experiments: Conduct at least 100 repeated experiments and eliminate abnormal data to ensure the representativeness of the statistical results.

[0080] Data analysis method: Statistical methods, such as mean value and standard deviation, are used to process a large amount of collected sample data to ensure that the calculated thermal conductivity G and thermal mass C have a high degree of scientific credibility.

[0081] Step 3: When the indoor ambient temperature is lower than the air conditioner set temperature, the air conditioner enters the virtual energy storage state, and the integrated energy interactive terminal calculates the virtual energy storage capacity of the air conditioner;

[0082] Based on the working characteristics of the air conditioner within the set temperature range, it is considered that the air conditioner can achieve a similar energy storage function by accumulating and releasing cold and heat when the outside temperature changes.

[0083] Specifically, the thermal conductivity G and thermal mass C measured by the integrated energy interactive terminal are used to calculate the virtual energy storage capacity E of the air-conditioning system within the set temperature range in the following way: storage , and interact with the integrated energy system to regulate:

[0084]

[0085] Among them, T in is the indoor temperature, T set It is the air conditioner set temperature.

[0086] For example, the user sets the air conditioning temperature T set The integrated energy interactive terminal detects the indoor temperature T in 28℃,

[0087]

[0088] Step 4: When the air conditioner set temperature changes, the integrated energy interactive terminal calculates the charging and discharging power of the air conditioner as virtual energy storage according to the virtual energy storage capacity, and performs virtual energy storage regulation of the air conditioner.

[0089] The virtual energy storage charging and discharging power P charge / discharge The calculation formula is:

[0090]

[0091] in: is the rate of change of the set temperature.

[0092] For example, to calculate the virtual energy storage discharge power: Assume that the user adjusts the air conditioner setting temperature from 25°C to 23°C, and the adjustment takes 3 minutes. The set temperature change rate is:

[0093]

[0094] Calculate the virtual energy storage charging power:

[0095] P charge =-0.8×(-40)-0.4×(28-25)×(-40)

[0096] =32-0.4×3×(-40)

[0097] =32+48

[0098] =80kW

[0099] The result is positive, which means that the air conditioner is in charging state at this time, and the charging power is 80kW, that is, the air conditioner consumes more electricity to increase the cooling power.

[0100] Calculate the virtual energy storage discharge power: Then, the user raises the air conditioner set temperature from 23°C to 25°C. The adjustment takes 4 minutes (4÷60=1 / 15h). The set temperature change rate is:

[0101]

[0102] Calculate the virtual energy storage discharge power:

[0103] P discharge =-0.8×30-0.4×(28-25)×30

[0104] =-24-0.4×3×30

[0105] =-24-36

[0106] =-60kW

[0107] The result is negative, and the absolute value of 60kW indicates that the air conditioner is in a discharging state at this time, and the discharge power is 60kW, that is, the air conditioner reduces power consumption and uses stored cold energy to maintain indoor temperature.

[0108] Embodiment 2 of the present invention provides a system for dynamically measuring thermal parameters of air conditioners and controlling virtual energy storage under a comprehensive energy interactive terminal, wherein the system for dynamically measuring thermal parameters of air conditioners and controlling virtual energy storage comprises:

[0109] The parameter measurement module is used for the integrated energy interactive terminal to monitor the indoor and outdoor temperatures and air conditioning power after the air conditioner is started, and to measure the thermal conductivity G using the monitoring data when the indoor temperature change rate is zero; the integrated energy interactive terminal records the indoor and outdoor temperatures after the air conditioner is turned off, and measures the thermal mass C based on the thermal conductivity G and the recorded indoor and outdoor temperatures;

[0110] The virtual energy storage capacity calculation module is used for the integrated energy interactive terminal to monitor the outdoor temperature. When the indoor ambient temperature is lower than the air conditioner set temperature, the air conditioner enters the virtual energy storage state, and the integrated energy interactive terminal calculates the virtual energy storage capacity of the air conditioner;

[0111] The virtual energy storage control module is used to calculate the charging and discharging power of the air conditioner as virtual energy storage when the air conditioner set temperature changes, and perform virtual energy storage control of the air conditioner.

[0112] The comprehensive energy interactive terminal is integrated into the air conditioning system;

[0113] The comprehensive energy interactive terminal has the following functions:

[0114] a) Data collection and processing: The terminal can collect key parameters such as indoor and outdoor temperature and power of the air-conditioning system in real time, and perform necessary data processing to ensure the accuracy and availability of the data.

[0115] b) Intelligent control algorithm: The terminal has a built-in intelligent control algorithm, which dynamically adjusts the operation mode of the air-conditioning system according to the collected data and the parameters set by the user to optimize the energy efficiency ratio and adapt to different environmental conditions. For example, when the air conditioner enters the energy storage state and the energy storage capacity is calculated to be 4.2kW·h, the intelligent control algorithm automatically adjusts the operating frequency of the air-conditioning compressor according to this result and the speed of change of the indoor temperature. If the indoor temperature drops slowly, the algorithm will increase the compressor frequency to enhance the cooling effect; if it drops quickly, the compressor frequency will be reduced to avoid over-cooling. When the user lowers the set temperature and calculates the charging power to be 80kW, the algorithm controls the speed of the air-conditioning fan according to this power value and the temperature difference between indoor and outdoor. If the temperature difference between indoor and outdoor is large, the fan speed is increased to speed up the cold and heat exchange; if the temperature difference is small, the fan speed is reduced to save energy. When the set temperature is increased and the discharge power is calculated to be 60kW, the algorithm adjusts the operating parameters of the air conditioner in combination with the rise in indoor temperature, so that the indoor temperature rises steadily and the energy consumption is minimized.

[0116] c) Remote control and monitoring: The terminal supports remote control function, allowing users or system administrators to monitor and operate the air conditioning system through the Internet or other communication means.

[0117] d) User interface: Provide a friendly user interface so that users can intuitively understand the operating status and energy consumption of the air-conditioning system and make manual adjustments as needed.

[0118] e) Communication protocol compatibility: The terminal is designed with a highly compatible communication protocol and can seamlessly connect with air-conditioning systems and smart devices of various brands.

[0119] f) Energy efficiency optimization: The terminal optimizes the operation of the air conditioning system based on real-time data and preset strategies, improves the overall energy efficiency ratio, and adapts to efficient and energy-saving operation in different seasons or under the temperature difference between day and night. For example, during the high temperature period during the day, the outdoor temperature is maintained at a high temperature (such as 32°C) for a long time, and the indoor activities generate more heat, and the air conditioner is continuously in the energy storage and cooling state. According to the real-time monitoring data and preset strategies, when the indoor temperature is close to the set temperature, the terminal appropriately reduces the cooling power of the air conditioner, uses the indoor thermal inertia to maintain a comfortable temperature for a period of time, reduces the number of compressor starts and stops, and reduces energy consumption. In the evening, the outdoor temperature begins to drop, assuming it drops to 28°C. The terminal perceives this change in real time, and combined with the previously calculated energy storage capacity and charging and discharging power, it determines that the operating power of the air conditioner can be further reduced. For example, the compressor frequency is reduced by one gear, and the fan speed is appropriately reduced, so as to achieve efficient and energy-saving operation while ensuring a comfortable indoor temperature. If the outdoor temperature continues to drop to close to the indoor set temperature, the terminal can control the air conditioner to stop cooling, and use natural ventilation and the cold energy stored indoors to maintain the indoor temperature until the outdoor temperature rises again or the indoor temperature exceeds the set range, then restart the air conditioner and adjust the operating mode.

[0120] The air conditioning system integrated with the comprehensive energy interactive terminal includes hardware and control system, wherein the control system performs thermal parameter measurement, virtual energy storage capacity calculation and air conditioning load adjustment according to the set temperature change through the comprehensive energy interactive terminal, and interacts with other energy equipment for regulation.

[0121] The control system can optimize the operation strategy of the air conditioner and the overall energy system based on the thermal parameter measurement results of the comprehensive energy interactive terminal and the virtual energy storage management algorithm, improve the energy efficiency ratio, and adapt to efficient and energy-saving operation in different seasons or day and night temperature difference environments.

[0122] The control system can exchange data and execute instructions with the integrated energy interactive terminal to achieve thermal parameter measurement, virtual energy storage capacity calculation and intelligent regulation of air conditioning load.

[0123] Embodiment 3 of the present invention provides a terminal, including a processor and a storage medium; the storage medium is used to store instructions; the processor is used to operate according to the instructions to execute the steps of the method.

[0124] Embodiment 4 of the present invention provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of the method when executed by a processor.

[0125] Compared with the prior art, the beneficial effects of the present invention include at least:

[0126] The present invention is based on an integrated energy interactive terminal, which can accurately obtain key thermal parameters such as thermal conductivity and thermal mass of the air-conditioning system in the actual operating environment, and on this basis constructs a virtual energy storage capacity and charging and discharging power model of the air-conditioning system, combines the air-conditioning working mode with the energy storage concept, and interacts with the integrated energy system. It flexibly dispatches the air-conditioning load according to outdoor temperature fluctuations, realizes the energy storage operation of the air-conditioning system, thereby improving energy utilization efficiency, enhancing the intelligence level and adaptability of the air-conditioning system, and realizing intelligent management and energy efficiency optimization of the air-conditioning system.

[0127] The present invention realizes the accurate measurement of the key thermal parameters inherent in the air-conditioning system through real-time monitoring and regulation, and by introducing the concept of virtual energy storage, utilizes the working characteristics of the air-conditioning system to simulate the charging and discharging behavior of the energy storage system, and flexibly adjusts the air-conditioning operation state according to the ambient temperature fluctuation through the integrated energy interactive terminal, thereby realizing intelligent regulation of energy storage, effectively improving the energy efficiency ratio of the air-conditioning, reducing energy consumption, enhancing its adaptability and energy-saving effect under various climatic and environmental conditions, and promoting the interaction between the air-conditioning system and the integrated energy system as well as energy conservation and emission reduction.

[0128] In traditional methods, the calculation of virtual energy storage capacity and charge and discharge power usually only depends on temperature difference or power difference, while ignoring the thermal inertia (i.e. thermal mass C) and heat transfer capacity (i.e. thermal conductivity G) of the air conditioning system. The present invention calculates the virtual energy storage capacity of the air conditioner and the charge and discharge power as virtual energy storage by combining thermal conductivity G and thermal mass C, which can more accurately reflect the energy storage capacity and charge and discharge characteristics of the air conditioning system.

[0129] The present invention also takes into account the rate of change of the air conditioner set temperature when calculating the charging and discharging power of the air conditioner as a virtual energy storage. This enables virtual energy storage regulation to dynamically respond to temperature changes, thereby more flexibly adapting to different environmental conditions and user needs.

[0130] By accurately calculating the virtual energy storage capacity and the charging and discharging power, the system can intelligently adjust the air-conditioning operation according to the grid demand and the status of the energy equipment, optimize the energy distribution and improve the overall energy efficiency.

[0131] The model of the present invention can more accurately control the energy storage and release process of the air-conditioning system, reduce unnecessary energy consumption, and further improve the energy-saving effect of the air-conditioning system.
