Technical Field

[0001] The present invention relates to the field of thermal technology, and in particular to an intelligent control system for central heating using an air source heat pump. Background Art

[0002] With the continuous expansion of modern building scale and the improvement of people's demand for comfortable environment, central heating systems are increasingly used in public buildings such as large shopping malls and office buildings. However, traditional central heating systems often have problems such as slow response speed and low adjustment accuracy, resulting in poor heating effect and serious energy waste. Especially in the case of frequent climate change, how to improve the intelligence level of the heating system and achieve efficient and energy-saving heating control has become an important issue that needs to be solved urgently.

[0003] The patent document with the publication number CN109237583A discloses an air source heat pump centralized heating system and control method. The system includes: a plurality of air source heat pumps arranged in parallel and a water storage device connected to the air source heat pump, the water outlet of the water storage device is connected to the user end, the cold water discharged from the user end flows back to the air source heat pump through the water storage device for circulation, and the number of connections between the air source heat pump and the water storage device is adjustable. A control method is also provided, which starts all the air source heat pumps, provides hot water to the water storage device, and then supplies water to the user end, and gradually closes or opens the corresponding preset number of air source heat pumps according to the difference between the temperature of the hot water entering the water storage device and the first predetermined temperature, until the temperature of the hot water entering the water storage device reaches or is maintained at the first predetermined temperature. Whether to close or open the air source heat pump is determined only by detecting the difference between the temperature of the hot water in the water storage device and the predetermined temperature, which fails to accurately adjust according to the actual temperature conditions of different regions, and cannot effectively cope with the differences in heating demand in different regions, resulting in overheating or insufficient warmth in some regions. Furthermore, the switching of the heat pump is controlled based on a fixed temperature difference, and the temperature changes in the local area cannot be accurately controlled. Summary of the invention

[0004] To this end, the present invention provides an air source heat pump central heating intelligent control system to overcome the problems of poor heating effect and low energy utilization rate caused by slow response speed and low adjustment accuracy in the prior art.

[0005] To achieve the above object, the present invention provides an air source heat pump central heating intelligent control system, comprising:

[0006] A data acquisition module, used to monitor the real-time outdoor temperature of the heating area, the real-time total indoor temperature and the real-time thermal imaging images of each sub-area in the heating area, where the area of ​​each sub-area is a preset sub-area area;

[0007] a data analysis module connected to the data acquisition module, comprising a heat pump start-up unit and a thermal imaging recognition unit, wherein the heat pump start-up unit is used to start the heat pump in the heating area with a preset heat pump power according to the real-time outdoor temperature, the real-time total indoor temperature and the preset start-up temperature, and the thermal imaging recognition unit is used to extract the real-time temperature in the real-time thermal imaging image of each sub-area after the heat pump is turned on, and to confirm the high temperature area and the low temperature area according to each real-time temperature and the preset standard temperature;

[0008] A heating regulation module, connected to the data analysis module, comprises a calculation unit and an adjustment unit, wherein the calculation unit is used to calculate the proportion of high temperature zones and low temperature zones in the heating area according to the number of high temperature zones and low temperature zones to obtain the high temperature proportion and the low temperature proportion, and the adjustment unit is used to make a judgment according to the high temperature proportion, the low temperature proportion and the preset standard proportion to form a first judgment result, and make a corresponding adjustment to the power of the heat pump according to the first judgment result, or start the ventilation system;

[0009] The correction module is connected to the data acquisition module and the heating adjustment module respectively, and is used to make a judgment based on all real-time temperatures within a preset correction time and a preset standard fluctuation value to form a second judgment result, and correct the sub-region area according to the second judgment result.

[0010] Furthermore, the heat pump activation unit is used to activate the heat pump in the heating area with a preset heat pump power according to the real-time outdoor temperature, the real-time total indoor temperature and the preset activation temperature, and includes:

[0011] The heat pump activation unit activates the heat pump in the heating area with a preset heat pump power when the real-time total indoor temperature is lower than the activation temperature and the real-time outdoor temperature is lower than or equal to the real-time total indoor temperature.

[0012] Furthermore, the heat pump start-up unit is also used to calculate the difference between the real-time outdoor temperature and the real-time total indoor temperature to obtain the indoor and outdoor temperature difference when the real-time outdoor temperature is lower than the start-up temperature and the real-time outdoor temperature is higher than the real-time total indoor temperature. When the indoor and outdoor temperature difference is higher than the preset standard temperature difference, the heat pump start-up unit starts the heat pump in the heating area with a preset heat pump power.

[0013] Furthermore, the calculation unit is used to calculate the ratio of the number of high temperature areas to the total number of sub-areas to obtain the high temperature proportion;

[0014] The calculation unit is used to calculate the ratio of the number of low temperature areas to the total number of sub-areas to obtain the low temperature proportion.

[0015] Further, the adjustment unit is used to make a judgment according to the high temperature proportion, the low temperature proportion and the preset standard proportion to form a first judgment result, and to make a corresponding adjustment to the power of the heat pump according to the first judgment result, including:

[0016] When the high temperature proportion is greater than the standard proportion, the adjustment unit calculates the difference between the high temperature proportion and the standard proportion to obtain the high temperature proportion difference. When the high temperature proportion difference is greater than the preset standard proportion difference, the adjustment unit reduces the heat pump power according to the high temperature proportion difference, the standard proportion difference and the preset power adjustment coefficient.

[0017] Furthermore, when the low-temperature proportion is greater than the standard proportion, the adjustment unit calculates the difference between the low-temperature proportion and the standard proportion to obtain the low-temperature proportion difference. When the low-temperature proportion difference is greater than the preset standard proportion difference, the adjustment unit increases the heat pump power according to the low-temperature proportion difference, the standard proportion difference and the preset power adjustment coefficient.

[0018] Furthermore, the adjustment unit starts the ventilation system when the high temperature proportion is greater than the standard proportion and the high temperature proportion difference is less than or equal to a preset standard proportion difference.

[0019] Furthermore, the correction module is used to calculate the standard deviation of all real-time temperatures within the correction period to obtain a temperature fluctuation value. When the temperature fluctuation value is greater than the standard fluctuation value, the correction module increases the sub-region area according to the temperature fluctuation value, the standard fluctuation value and a preset correction coefficient.

[0020] Furthermore, the thermal imaging recognition unit is used to determine that a sub-region whose real-time temperature is greater than or equal to a standard temperature is a high temperature region.

[0021] Furthermore, the thermal imaging recognition unit is used to determine that a sub-region whose real-time temperature is lower than a standard temperature is a low-temperature region.

[0022] Compared with the prior art, the beneficial effect of the present invention is that, by real-time monitoring of the temperature and thermal imaging images inside and outside the heating area of ​​the shopping mall, the intelligent adjustment of the heating system is realized. The system can dynamically adjust the power of the heat pump and the opening status of the ventilation system according to the temperature distribution of different sub-areas, so as to ensure the uniformity of the heating effect and the maximization of energy efficiency. At the same time, the system adjusts the area of ​​each sub-area through the correction module, which effectively reduces energy waste, improves the accuracy and comfort of heating, and effectively solves the problems of poor heating effect and low energy utilization rate caused by slow response speed and low adjustment accuracy.

[0023] Furthermore, by dynamically adjusting the start time and power of the heat pump according to the size of the indoor and outdoor temperature difference and the real-time temperature conditions, the system can start heating in time when the temperature difference is large, avoiding unnecessary energy consumption.

[0024] Furthermore, the heat pump start unit can ensure that the heat pump is started in time when the indoor temperature is lower than the set value, ensuring that the temperature in the heating area reaches a comfortable level, while avoiding affecting the user's comfort and the overall effect of the system due to too low temperature.

[0025] Furthermore, by accurately identifying high temperature areas, the temperature distribution of the heating area can be effectively understood to avoid overheating or underheating problems.

[0026] Furthermore, by accurately identifying low-temperature areas, areas with insufficient heating can be discovered in a timely manner, thereby adjusting the power of the heat pump or starting the ventilation system.

[0027] Furthermore, by calculating the proportion of high temperature and low temperature, we can fully understand the temperature distribution in the heating area, help the system optimize the power adjustment strategy of the heat pump or start the ventilation system to ensure the uniformity of temperature distribution.

[0028] Furthermore, by adjusting the heat pump power according to the high temperature ratio difference, local overheating can be effectively prevented and energy waste can be avoided.

[0029] Furthermore, by increasing the heat pump power to quickly raise the temperature of the heating area, energy waste due to insufficient temperature can be avoided.

[0030] Furthermore, by starting the ventilation system to lower the temperature, energy waste and system overload caused by over-adjusting the heat pump power are avoided.

[0031] Furthermore, by increasing the area of ​​the sub-region, the responsiveness to temperature fluctuations can be improved, ensuring that the system can accurately capture temperature changes when the temperature fluctuations are large. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] See also Figure 1 As shown, it is a schematic diagram of the air source heat pump central heating intelligent control system of this embodiment;

[0041] This embodiment provides an air source heat pump central heating intelligent control system, including:

[0042] A data acquisition module, for monitoring the real-time outdoor temperature of the heating area in the large shopping mall through an outdoor temperature sensor arranged outside the large shopping mall, monitoring the real-time total indoor temperature through an indoor temperature sensor arranged inside the large shopping mall, and dividing the heating area into a plurality of sub-areas through a thermal imaging sensor arranged above the heating area and monitoring the real-time thermal imaging image of each sub-area, wherein the area of ​​each sub-area is a preset sub-area area;

[0043] a data analysis module connected to the data acquisition module, comprising a heat pump start-up unit and a thermal imaging recognition unit, wherein the heat pump start-up unit is used to start the heat pump in the heating area with a preset heat pump power according to the real-time outdoor temperature, the real-time total indoor temperature and the preset start-up temperature, and the thermal imaging recognition unit is used to extract the real-time temperature in the real-time thermal imaging image of each sub-area after the heat pump is turned on according to the image extraction algorithm, and confirm the high temperature area and the low temperature area according to each real-time temperature and the preset standard temperature;

[0044] A heating regulation module, connected to the data analysis module, comprises a calculation unit and an adjustment unit, wherein the calculation unit is used to calculate the proportion of high temperature zones and low temperature zones in the heating area according to the number of high temperature zones and low temperature zones to obtain the high temperature proportion and the low temperature proportion, and the adjustment unit is used to make a judgment according to the high temperature proportion, the low temperature proportion and the preset standard proportion to form a first judgment result, and make a corresponding adjustment to the power of the heat pump according to the first judgment result, or start the ventilation system;

[0045] The correction module is connected to the data acquisition module and the heating adjustment module respectively, and is used to make a judgment based on all real-time temperatures within a preset correction time and a preset standard fluctuation value to form a second judgment result, and correct the sub-region area according to the second judgment result.

[0046] The preset sub-area area refers to the area of ​​each monitoring area divided in the shopping mall. Depending on the layout of the shopping mall and the density of human traffic, it is usually set to 50-200 square meters. In this embodiment, it is set to 100 square meters, which is convenient for accurate adjustment according to different human traffic densities.

[0047] The preset start-up temperature refers to the outdoor temperature threshold that triggers the start of the heat pump. It depends on the insulation performance of the mall and the indoor comfortable temperature requirements, and is usually set to 5°C. In this embodiment, it is set to 5°C to ensure that the mall is heated in time when the outdoor temperature is low.

[0048] The heat pump power is the standard power when the heat pump is running. It depends on the area of ​​the mall and the heating demand, and is usually set to 75%-100% of the maximum heating load of the mall. In this embodiment, it is set to 80% to ensure heating efficiency and save energy.

[0049] The preset standard temperature refers to the ideal temperature in each sub-area. It depends on the target comfort temperature in the mall and is usually set to 20° C. In this embodiment, it is set to 22° C. to meet the comfort needs of customers in the mall.

[0050] The preset standard ratio refers to the expected ratio of the high temperature area to the low temperature area in the total area. Depending on the heat distribution of the mall, it is usually set to 40%-60% for the high temperature area. In this embodiment, it is set to 50% to ensure uniform heating.

[0051] The preset correction time refers to the time period used for data correction after the heat pump is running. It depends on the system response speed and is usually set to 5-10 minutes. In this embodiment, it is set to 8 minutes to ensure timely adjustment of the system.

[0052] The preset standard fluctuation value refers to the reference standard deviation used to determine the temperature fluctuation. It depends on the tolerance of temperature changes in the mall and is usually set to 1-3°C. In this embodiment, it is set to 2°C to ensure the stability of temperature control.

[0053] The system first obtains the real-time temperature and thermal imaging images inside and outside the mall through the data acquisition module. The data analysis module decides whether to turn on the heat pump based on this data, and determines the high and low temperature areas of each sub-area through the thermal imaging recognition unit. The heating adjustment module adjusts the power of the heat pump or starts the ventilation system to optimize the heating effect based on the calculation results of the proportion of these areas. The correction module dynamically corrects the area of ​​each sub-area according to the temperature fluctuations within the set time period to ensure the accuracy and efficiency of the heating system.

[0054] By real-time monitoring of the temperature and thermal imaging images inside and outside the shopping mall's heating area, intelligent adjustment of the heating system is achieved. The system can dynamically adjust the power of the heat pump and the opening status of the ventilation system according to the temperature distribution of different sub-areas, ensuring the uniformity of the heating effect and the maximization of energy efficiency. At the same time, the system effectively reduces energy waste and improves the accuracy and comfort of heating by adjusting the area of ​​each sub-area through the correction module, effectively solving the problems of poor heating effect and low energy utilization rate caused by slow response speed and low adjustment accuracy.

[0055] Please continue reading Figure 2 As shown, it is a determination logic diagram of the heat pump start unit of this embodiment for determining to start the heat pump;

[0056] Specifically, the heat pump activation unit is used to activate the heat pump in the heating area with a preset heat pump power according to the real-time outdoor temperature, the real-time total indoor temperature and the preset activation temperature, and includes:

[0057] The heat pump activation unit activates the heat pump in the heating area with a preset heat pump power when the real-time total indoor temperature is lower than the activation temperature and the real-time outdoor temperature is lower than or equal to the real-time total indoor temperature.

[0058] When the real-time total indoor temperature is lower than the preset start-up temperature, the heat pump start-up unit will start the heat pump in the heating area according to the set heat pump power to increase the indoor temperature.

[0059] The heat pump start-up unit can ensure that the heat pump is started in time when the indoor temperature is lower than the set value, ensuring that the temperature in the heating area reaches a comfortable level, while avoiding affecting the user's comfort and the overall effect of the system due to too low temperature.

[0060] Specifically, the heat pump start-up unit is also used to calculate the difference between the real-time outdoor temperature and the real-time total indoor temperature when the real-time outdoor temperature is lower than the start-up temperature and the real-time outdoor temperature is higher than the real-time total indoor temperature to obtain the indoor and outdoor temperature difference. When the indoor and outdoor temperature difference is higher than the preset standard temperature difference, the heat pump start-up unit starts the heat pump in the heating area with a preset heat pump power.

[0061] The preset standard temperature difference is the temperature difference used to determine whether the heat pump needs to be turned on. It is usually a preset critical difference between the indoor and outdoor temperatures. It depends on the building's thermal insulation performance, indoor comfort requirements, and local climatic conditions. It is usually set between 5°C and 10°C to ensure that the indoor temperature can quickly return to a comfortable range. In this embodiment, the standard temperature difference is set to 8°C to meet the heating needs of large shopping malls. It can start heating in time when the indoor and outdoor temperature difference is large, ensuring that the indoor temperature quickly reaches the comfort range, while avoiding energy waste caused by frequent startup of the heat pump.

[0062] When the real-time outdoor temperature is lower than the start-up temperature and higher than the total indoor temperature, the system calculates the indoor and outdoor temperature difference through the heat pump start-up unit. When the indoor and outdoor temperature difference is greater than the preset standard temperature difference, the system will start the heat pump in the heating area with the preset heat pump power to ensure that the heating is turned on in time when the temperature difference is large and maintain the indoor temperature stable. At the same time, the system also dynamically adjusts the heating power and ventilation system by real-time monitoring the temperature and thermal imaging images of each sub-area in the heating area to optimize the heating effect.

[0063] By dynamically adjusting the start time and power of the heat pump according to the size of the indoor and outdoor temperature difference and the real-time temperature conditions, the system can start heating in time when the temperature difference is large, avoiding unnecessary energy consumption.

[0064] Please continue reading Figure 3 As shown, it is a determination logic diagram of the high temperature area determined by thermal imaging recognition in this embodiment;

[0065] Specifically, the thermal imaging recognition unit is used to determine that a sub-region whose real-time temperature is greater than or equal to the standard temperature is a high temperature region.

[0066] The thermal imaging recognition unit analyzes the temperature of each sub-area in the real-time thermal imaging image and determines the sub-area with a temperature greater than or equal to the preset standard temperature as a high temperature area. This process is completed by real-time analysis of thermal imaging data and comparison with the standard temperature.

[0067] By accurately identifying high temperature areas, the temperature distribution of the heating area can be effectively understood to avoid overheating or underheating problems.

[0068] Please continue reading Figure 4 As shown, it is a determination logic diagram of the low temperature zone determined by thermal imaging recognition in this embodiment;

[0069] Specifically, the thermal imaging recognition unit is used to determine that a sub-region whose real-time temperature is lower than a standard temperature is a low-temperature region.

[0070] The thermal imaging recognition unit analyzes the temperature of each sub-area in the real-time thermal imaging image and determines the sub-area with a temperature lower than the preset standard temperature as a low temperature area. This process is achieved by comparing the real-time temperature data and setting the standard temperature.

[0071] By accurately identifying low-temperature areas, areas with insufficient heating can be discovered in a timely manner, so that the power of the heat pump can be adjusted or the ventilation system can be activated.

[0072] Specifically, the calculation unit is used to calculate the ratio of the number of high temperature areas to the total number of sub-areas to obtain the high temperature proportion;

[0073] The calculation unit is used to calculate the ratio of the number of low temperature areas to the total number of sub-areas to obtain the low temperature proportion.

[0074] The calculation unit calculates the high temperature ratio and the low temperature ratio by counting the number of high temperature areas and low temperature areas and comparing them with the total number of sub-areas. These ratios reflect the distribution of high temperature and low temperature areas in the heating area.

[0075] By calculating the proportion of high temperature and low temperature, we can fully understand the temperature distribution in the heating area, help the system optimize the power adjustment strategy of the heat pump or start the ventilation system to ensure the uniformity of temperature distribution.

[0076] Specifically, the adjustment unit is used to make a judgment according to the high temperature proportion, the low temperature proportion and the preset standard proportion to form a first judgment result, and to make a corresponding adjustment to the power of the heat pump according to the first judgment result, including:

[0077] When the high temperature proportion is greater than the standard proportion, the adjustment unit calculates the difference between the high temperature proportion and the standard proportion to obtain the high temperature proportion difference. When the high temperature proportion difference is greater than the preset standard proportion difference, the adjustment unit reduces the heat pump power according to the high temperature proportion difference, the standard proportion difference and the preset power adjustment coefficient.

[0078] The preset standard ratio difference is a threshold used to judge the deviation between the high temperature ratio and the low temperature ratio and their standard values ​​to determine whether the heat pump power needs to be adjusted. It usually depends on the actual usage of the heating area and the adjustment sensitivity of the heat pump, reflecting the tolerance range when the high temperature ratio deviates from the standard value. The setting range of the standard ratio difference is generally between 5% and 10%, and the specific value depends on the design requirements and actual operation of the system. In this embodiment, the preset standard ratio difference is set to 5%, which helps to adjust the heat pump power in time when the high temperature area ratio deviates slightly from the standard value, thereby improving the responsiveness and stability of the system.

[0079] When the adjustment unit detects that the high temperature ratio is greater than the standard ratio, the difference between the high temperature ratio and the standard ratio is calculated to obtain the high temperature ratio difference. If the high temperature ratio difference exceeds the preset standard ratio difference, the heat pump power is adjusted to reduce its output according to the difference and the preset power adjustment coefficient.

[0080] By adjusting the heat pump power according to the difference in high temperature proportion, local overheating can be effectively prevented and energy waste can be avoided.

[0081] Specifically, when the low-temperature proportion is greater than the standard proportion, the adjustment unit calculates the difference between the low-temperature proportion and the standard proportion to obtain the low-temperature proportion difference. When the low-temperature proportion difference is greater than the preset standard proportion difference, the adjustment unit increases the heat pump power according to the low-temperature proportion difference, the standard proportion difference and the preset power adjustment coefficient.

[0082] When the adjustment unit detects that the low temperature ratio is greater than the standard ratio, it calculates the difference between the low temperature ratio and the standard ratio to obtain the low temperature ratio difference. If the low temperature ratio difference exceeds the preset standard ratio difference, the adjustment unit increases the power of the heat pump according to the low temperature ratio difference, the standard ratio difference and the preset power adjustment coefficient to improve the heating effect.

[0083] By increasing the power of the heat pump to quickly raise the temperature of the heating area, energy waste caused by insufficient temperature can be avoided.

[0084] Wherein, P'=P±[C×(LR)], P' is the adjusted heat pump power; P is the preset heat pump power; C is the preset power adjustment coefficient; L is the low temperature ratio; R is the standard ratio; ± is the increase or decrease of power according to the difference between the high temperature ratio and the low temperature ratio;

[0085] When adjusting to increase power: If L>R and LR>D, D is the preset standard ratio difference, use "+".

[0086] When adjusting to reduce power: If L≤R or LR≤D, use "-" or start the ventilation system.

[0087] Specifically, the adjustment unit starts the ventilation system when the high temperature proportion is greater than the standard proportion and the high temperature proportion difference is less than or equal to a preset standard proportion difference.

[0088] When the adjustment unit detects that the high temperature ratio is greater than the standard ratio and the high temperature ratio difference is less than or equal to the preset standard ratio difference, the adjustment unit starts the ventilation system to reduce the temperature of the high temperature area and balance the overall temperature distribution.

[0089] By starting the ventilation system to lower the temperature, energy waste and system overload caused by over-adjusting the heat pump power are avoided.

[0090] Specifically, the correction module is used to calculate the standard deviation of all real-time temperatures within the correction period to obtain a temperature fluctuation value. When the temperature fluctuation value is greater than the standard fluctuation value, the correction module increases the sub-region area according to the temperature fluctuation value, the standard fluctuation value and the preset correction coefficient. Among them, A'=A+C×(σ-S), A' is the corrected sub-region area, A is the preset sub-region area, C is the preset correction coefficient, σ is the calculated temperature fluctuation value, that is, the standard deviation, and S is the preset standard fluctuation value.

[0091] The preset correction coefficient is a proportional factor used to adjust the sub-region area, which determines the adjustment range of the sub-region area when the temperature fluctuation value exceeds the standard fluctuation value. It depends on the sensitivity requirements of the system and its adaptability to temperature fluctuations. For example, a higher correction coefficient may make the system more sensitive to temperature changes and increase the adjustment range; a lower correction coefficient makes the adjustment range smaller. It is usually set between 0.5 and 2, and the specific value depends on the system design requirements and actual application. This embodiment is set to 1, which can provide a moderate adjustment range to ensure that the system has a reasonable responsiveness to temperature fluctuations, which can avoid excessive adjustment and make appropriate corrections in the case of large fluctuations.

[0092] The standard fluctuation value refers to the standard deviation of real-time temperature data within a certain period of time. It reflects the degree of discreteness or fluctuation range of temperature data. It depends on the system's expected range of ambient temperature changes, the temperature fluctuations in the actual operating environment, and user needs. For example, a larger standard fluctuation value is suitable for environments with large temperature fluctuations. It is usually set between 1.0 and 3.0°C, and the specific value depends on the temperature fluctuation range of the actual application scenario. This embodiment is set to 1.5°C, which effectively covers the temperature changes in general environments, while avoiding frequent adjustments caused by small fluctuations, ensuring the stability and effectiveness of the system.

[0093] The preset correction time is the time period used to calculate the temperature fluctuation value, which is usually a time window for real-time data collection. The data within this time period is used to evaluate the volatility of the temperature and adjust the sub-area area. It depends on the environmental characteristics, such as the actual temperature fluctuations in large shopping malls and the response speed of the heating system. It is usually set to a time period of 10 to 30 minutes to balance the representativeness of the data and the response speed of the system. This embodiment is set to 20 minutes, which can effectively capture the trend of temperature changes and avoid frequent adjustments due to fluctuations in a short period of time.

[0094] The correction module will calculate the standard deviation of all real-time temperatures within the preset correction time to obtain the temperature fluctuation value. When the temperature fluctuation value is greater than the standard fluctuation value, the correction module will increase the sub-region area according to the temperature fluctuation value, the standard fluctuation value and the preset correction coefficient to improve the coverage accuracy of the thermal imaging image and the representativeness of the data collection.

[0095] By increasing the area of ​​the sub-region, the response capability to temperature fluctuations can be improved, ensuring that the system can accurately capture temperature changes when the temperature fluctuations are large.
