Description

Technical Field

[0001] The present invention relates to the field of base station energy saving technology, and specifically to an energy saving system and method for a 5G communication base station based on data analysis. Background Art

[0002] Early mobile communication networks were mainly based on voice communication, and the energy consumption of base stations was relatively low. With the development of the network, data services have gradually increased, and the power consumption of base stations has also increased accordingly. With the rise in energy prices and the expansion of network scale, the electricity costs of operators have increased significantly; and with the development of information technology and the advent of the 5G communication era, 5G networks require denser base station deployment than 4G, especially in urban areas, which increases the challenge of overall energy consumption. 5G introduces high frequency bands such as millimeter waves. Although it provides higher bandwidth, the signal coverage distance is small and more base stations are required; with the increase in the number of base stations, the energy loss is even greater, and the energy consumption required for cooling equipment for cooling base stations accounts for a large proportion of the total energy consumption; with the increase in the number of base stations, the distance and range of repeated signal coverage in the region will inevitably increase. How to make use of waste without affecting the signal strength and experience of users, adjust the signal coverage distance of base stations, reduce the use of cooling equipment in base stations, and greatly reduce the energy loss of base stations is crucial. Summary of the invention

[0003] The purpose of the present invention is to provide a 5G communication base station energy-saving system and method based on data analysis to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A 5G communication base station energy saving method based on data analysis, the method comprising the following steps:

[0006] S100, collecting the transmission power of the 5G communication base station in history and the signal coverage distance under different transmission powers, and calculating the distance power function of the transmission power of the base station and the signal coverage distance;

[0007] Furthermore, the specific steps of calculating the distance power function of the base station's transmission power and signal coverage distance are as follows:

[0008] S101. Collect the transmission power of 5G communication base stations in history and the signal coverage distance under different transmission powers. Suppose the different transmission powers of base stations in the collected history are

[0009] {G1, G2, G3, ..., G n}, G1, G2, G3, ..., G nrepresents the 1st, 2nd, 3rd, ..., nth transmission power in the base station in the collected history, where n is a positive integer; let the signal coverage distance corresponding to the different transmission powers in the collected base station be {L1, L2, L3, ..., L n}, L1, L2, L3, ..., L n Indicates the signal coverage distance corresponding to the 1st, 2nd, 3rd, ..., nth transmission power in the collected base station;

[0010] S102. Draw a graph using the collected historical transmission power of 5G communication base stations and the signal coverage distances at different transmission powers, with the transmission power as the independent variable and the signal coverage distance as the variable; use the least squares method to calculate the linear regression function of the transmission power and the signal coverage distance, and use the calculated linear regression function as the distance power function of the base station L = a1 × G + b1, where a1 represents the slope of the distance power function, and b1 represents the intercept of the distance power function.

[0011] By analyzing the transmission power and signal coverage distance of the base station in history, the relationship function between the transmission power and the signal coverage distance is obtained by linear regression calculation. The relationship function can clearly reflect the changing relationship between the transmission power and the signal coverage distance, and the signal coverage distance can be controlled by controlling the transmission power of the base station.

[0012] S200, collecting the heating rate of the 5G communication base station at different transmission powers in history to calculate the power heating function, collecting the cooling rate in the base station when natural ventilation without using cooling equipment in history, and calculating the ventilation cooling rate in the base station; collecting the temperature in the base station when the base station is cooled in history, and calculating the cooling threshold in the base station;

[0013] Furthermore, the specific steps for calculating the power heating function, ventilation cooling rate and cooling threshold are as follows:

[0014] S201, collect the heating rates of 5G communication base stations at different transmission powers in history, and assume that the collected heating rates at different transmission powers are {Fs1, Fs2, Fs3, ..., Fs m}, Fs1, Fs2, Fs3,..., Fs m represents the heating rate at the 1st, 2nd, 3rd, ..., mth transmission power in the base station in the collected history, where m is a positive integer; the transmission power in the base station collected in S101 is used as the independent variable, and the collected heating rate is used as the variable to draw a curve graph, and the linear regression curve of the transmission power and the heating rate is calculated using the same method as in S102, and the calculated linear regression function is used as the power heating function of the base station Fs=a2×G+b2, where a2 represents the slope of the power heating function, and b2 represents the intercept of the power heating function;

[0015] S202, collect the cooling rate in the base station when natural ventilation without using cooling equipment in the history {Zs1, Zs2, Zs3, ..., Zs k}, Zs1, Zs2, Zs3,..., Zs k Indicates the 1st, 2nd, 3rd, ..., kth cooling rate in the base station when natural ventilation without using cooling equipment in the collected history, k is a positive integer; the average value of the cooling rate of the base station during k natural ventilation is calculated as the ventilation cooling rate Ts of the base station, and the formula is: In the formula, k is the number of cooling rates in the base station during natural ventilation in the collected history;

[0016] S203, collecting the temperature in the base station when the base station is cooled down in the history {W1, W2, W3, ..., W j}, W1, W2, W3, ..., W j It represents the temperature inside the base station when the base station is subjected to the 1st, 2nd, 3rd, ..., jth cooling treatment in the collected history; the cooling threshold of the base station is calculated by the average value and the standard deviation, and the formula is: Wy=Wp-st_w, where Wp represents the average value of j temperatures in the collected history, st_w represents the standard deviation of j temperatures in the collected history, and Wy represents the cooling threshold of the base station.

[0017] The greater the transmission power of the base station during operation, the faster the heating rate of the device will be. Therefore, the calculated transmission power and heating rate can clearly show the relationship between the transmission power and heating rate of the base station. When the temperature of the base station is too high and the base station is cooled down, the transmission power can be controlled to reduce the heating rate of the base station to achieve the purpose of cooling.

[0018] S300, pairing adjacent base stations to form a base station pair, collecting real-time temperatures of two base stations in the base station pair, using the base station that needs to be cooled as the cooling base station in the base station pair, and using the other base station as a replacement base station, and using the cooling threshold to determine whether a single base station in the base station pair needs to be cooled;

[0019] Furthermore, the specific steps of using the temperature reduction threshold to determine whether a single base station in the same base station pair needs to be cooled are:

[0020] S301, collect the geographical location of the base station, pair the two nearest adjacent base stations to form a base station pair, collect the real-time temperatures of the two base stations in the base station pair in real time, which are Ws1 and Ws2 respectively, and use the cooling threshold to judge the real-time temperatures of the two base stations collected in real time. When Ws≥Wy, it is judged that the corresponding base station needs to be cooled, and the base station that needs to be cooled is used as the cooling base station Pj in the base station pair. When Ws<Wy, it is judged that the corresponding base station does not need to be cooled, and the base station that does not need to be cooled is used as the replacement base station Pd in ​​the base station pair; Ws∈{Ws1, Ws2}, Ws represents the real-time temperature of the two base stations in the base station pair;

[0021] S302. After determining the cooling base station and the replacement base station of the same base station pair, the determined same base station pair is constructed as (Pj, Pd). The calculated cooling threshold is used to determine the real-time temperature of the base station, and the temperature of the base station can be automatically monitored to avoid abnormal operation of the base station due to excessive temperature, thereby reducing the probability of abnormality of the base station.

[0022] S400, when it is determined that equipment cooling is required in a single base station, real-time transmission power of two base stations in the same base station pair is collected in real time, and the same coverage distance in the same base station pair is calculated using a distance power function, and finally the power reduction amount of the cooling base station is calculated;

[0023] Furthermore, the specific steps for calculating the amount of power that can be reduced for cooling the base station are:

[0024] S401. When it is determined that equipment cooling is required in a single base station, the real-time transmission powers of two base stations in the same base station pair are collected in real time, which are Gj and Gd respectively. The relative distance between two adjacent base stations in the same base station pair is calculated as Lx using the distance formula between two points. The collected real-time transmission powers of adjacent base stations in the same base station pair are substituted into the distance power function, and the formula is:

[0025] Lj=a1×Gj+b1

[0026] Ld=a1×Gd+b1

[0027] In the formula, Lj represents the signal coverage distance of the cooling base station, and Ld represents the signal coverage distance of the replacement base station; the same coverage distance within the same base station pair is calculated using the signal coverage distance and relative distance of two base stations in the same base station pair, and the formula is: Lt = Lj + Ld - Lx, where Lt represents the calculated same coverage distance within the same base station pair;

[0028] S402, substituting the calculated same coverage distance within the same base station pair into the distance power function, and calculating the amount of power that can be reduced for the cooling base station, the formula is: In the formula, Gk represents the calculated amount of power reduction that can be achieved in the cooling base station.

[0029] In order to ensure the user's signal, when adjusting the transmission power of the base station, it is necessary to ensure that there is still signal coverage within the adjusted distance. Therefore, the same coverage distance of adjacent base stations is the adjustable range of the signal coverage distance of the base station. The adjustment amount of the transmission power is calculated according to the adjustment range of the signal coverage distance. Within the adjustment amount, the user's signal strength is guaranteed, and the purpose of cooling can be achieved by reducing the transmission power of the base station and reducing the heating rate.

[0030] S500, using the collected real-time transmission power of the cooling base station within the same base station to calculate the real-time heating rate, compare the real-time heating rate with the ventilation cooling rate, and calculate the required power reduction amount of the cooling base station;

[0031] Furthermore, the specific steps for calculating the required power reduction of the cooling base station are as follows:

[0032] S501, substituting the real-time transmission power of the cooling base station collected in S401 into the power heating function of the base station to calculate the real-time heating rate, the formula is:

[0033] Fsj=a2×Gj+b2

[0034] In the formula, Fsj represents the calculated real-time heating rate of the cooling base station;

[0035] S502, using the ventilation cooling rate to determine the real-time heating rate, when Fsj>Ts, determine that the cooling base station needs cooling equipment for cooling, when Fsj≤Ts, determine that the cooling base station does not need cooling equipment for cooling; when it is determined that the cooling base station needs to use cooling equipment for cooling, calculate the difference between the real-time heating rate and the ventilation cooling rate, the formula is: Fc=Fsj-Ts, where Fc represents the difference between the calculated real-time heating rate and the ventilation cooling rate; substitute the calculated difference into the power heating function of the base station to calculate the required power reduction amount of the cooling base station,

[0036] The formula is: In the formula, Gx represents the calculated required power reduction of the cooling base station.

[0037] The real-time heating rate is obtained by calculating the real-time transmission power of the base station. When the real-time heating rate is greater than the ventilation cooling rate, the temperature inside the base station can only be reduced by using cooling equipment. In order to reduce the use of cooling equipment and reduce the energy consumption of the base station, the transmission power of the base station is reduced within the adjustable range, so that the heating rate of the base station is reduced and the use of cooling equipment is reduced, thus achieving energy saving for the base station operation.

[0038] S600, comprehensively analyzing the calculated power reduction amount and required power reduction amount of the cooling base station to obtain the actual power reduction amount of the cooling base station, reducing the transmission power of the cooling base station by using the actual power reduction amount, and then comprehensively analyzing to formulate a cooling strategy for the cooling base station;

[0039] Furthermore, the specific steps for formulating a cooling strategy for a cooling base station are as follows:

[0040] S601. Calculate the difference between the power that can be reduced and the power that needs to be reduced of the cooling base station, the formula is: Gc=Gk-Gx, where Gc represents the difference between the power that can be reduced and the power that needs to be reduced of the cooling base station; when Gc≥0, determine that the same coverage distance of the same base station pair can meet the required power reduction of the cooling base station, and use the required power reduction of the cooling base station as the actual power reduction Gs of the cooling base station; use the actual power reduction to reduce the power of the cooling base station, and the reduced signal coverage distance after the power of the cooling base station is reduced is covered by the replacement base station; when the power of the cooling base station is reduced, use the ventilation device to cool the cooling base station;

[0041] S602. When Gc<0, it is determined that the same coverage distance of the same base station pair cannot meet the required power reduction of the cooling base station, and the reducible power of the cooling base station is used as the actual power reduction Gs of the cooling base station; the power of the cooling base station is reduced by using the actual power reduction, and the reduced signal coverage distance after the power of the cooling base station is reduced is covered by the replacement base station; when the power of the cooling base station is reduced, the cooling base station is cooled by a combination of ventilation devices and cooling equipment.

[0042] S700: When cooling down a cooling base station in the same base station pair, determine the temperature of the replacement base station in real time; when the replacement base station needs to be cooled down, exchange the cooling base station with the replacement base station to achieve alternating cooling work in the same base station pair.

[0043] Furthermore, the specific steps for realizing the alternating cooling work within the same base station are as follows:

[0044] S701, when cooling down the cooling base station in the same base station pair, the temperature of the replacement base station is judged in real time, when Wd≥Wy, it is judged that the replacement base station needs to be cooled, and the temperature of the cooling base station after cooling is judged again, when Wjh<Wy, it is judged that the cooling base station does not need to be cooled temporarily; Wd represents the real-time temperature of the replacement base station, and Wjh represents the temperature of the cooling base station after cooling;

[0045] S702. When it is determined that the replacement base station needs to be cooled down and the cooling base station does not need to be cooled down temporarily, the cooling base station and the replacement base station are alternated within the same base station pair, and the actual power reduction amount is calculated for the replacement base station, and a cooling strategy is formulated to cool it down; when the replacement base station is cooled down, the cooling base station covers the signal coverage distance that is reduced when the replacement base station is cooled down, and then the real-time temperatures of the two base stations within the same base station pair are determined in real time in turn, and the cooling is performed alternately.

[0046] Perform alternating cooling within the same base station pair, and use the same coverage distance to reduce the base station's transmission power during cooling, so that the base station's heating rate is reduced, the use of cooling equipment is reduced, or even avoided, and cooling is completed only through ventilation devices; and the replacement base station can replace the cooling base station to cover the reduced signal distance, and will not affect the base station's signal coverage and the user's signal strength;

[0047] A 5G communication base station energy-saving system based on data analysis, the 5G communication base station energy-saving system includes a data collection module, a function calculation module, a base station analysis module, a temperature judgment module, a program formulation module and an alternating cooling module;

[0048] The data collection module is used to collect the transmission power, signal coverage distance, heating rate and cooling rate in the history of the base station;

[0049] The function calculation module is used to analyze the transmission power, signal coverage distance, and heating rate of the base station in the collected history, and calculate the distance power function and the power heating function respectively;

[0050] The base station analysis module is used to analyze the positions of adjacent base stations and build base station pairs; analyze and calculate the cooling rate of the base station during natural ventilation to obtain the ventilation cooling rate; analyze the temperature of the base station during cooling in history to calculate the cooling threshold of the base station;

[0051] The temperature judgment module is used to collect the real-time temperatures of two base stations in the same base station pair, and use the base station's temperature reduction threshold to determine whether the base station needs to be cooled;

[0052] The scheme formulation module is used to respectively calculate the amount of power that can be reduced and the amount of power that needs to be reduced of the cooling base station, conduct a comprehensive analysis, and calculate the actual amount of power reduction; formulate a cooling strategy for the cooling base station according to the actual amount of power reduction;

[0053] The alternating cooling module is used to make real-time judgment on the temperature of the replacement base station in the same base station pair. When the replacement base station needs to be cooled and the cooling base station no longer needs to be cooled after cooling, the cooling base station and the replacement base station are alternated; the temperatures of the two base stations in the same base station pair are judged in turn to achieve alternating cooling.

[0054] The function calculation module includes a distance power function unit and a power heating function unit;

[0055] The distance power function unit is used to draw a curve graph using the transmission power and signal coverage distance of the base station collected in the history, and obtain the distance power function of the base station by linear regression calculation;

[0056] The power heating function unit is used to draw a curve graph using the transmission power and heating rate of the base station in the collected history, and obtain the power heating function of the base station by linear regression calculation.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] 1. The present invention calculates the functional relationship among the transmission power, signal coverage distance and heating rate in the base station.

[0064] Example: Figure 1-Figure 2As shown, the present invention provides a technical solution.

[0065] A 5G communication base station energy saving method based on data analysis, the method comprising the following steps:

[0066] S100, collecting the transmission power of the 5G communication base station in history and the signal coverage distance under different transmission powers, and calculating the distance power function of the transmission power of the base station and the signal coverage distance;

[0067] The specific steps for calculating the distance power function of the base station's transmission power and signal coverage distance are:

[0068] S101. Collect the transmission power of 5G communication base stations in history and the signal coverage distance under different transmission powers. Suppose the different transmission powers of base stations in the collected history are

[0069] {G1, G2, G3, ..., G n}, G1, G2, G3, ..., G n represents the 1st, 2nd, 3rd, ..., nth transmission power in the base station in the collected history, where n is a positive integer; let the signal coverage distance corresponding to the different transmission powers in the collected base station be {L1, L2, L3, ..., L n}, L1, L2, L3, ..., L n Indicates the signal coverage distance corresponding to the 1st, 2nd, 3rd, ..., nth transmission power in the collected base station;

[0070] S102. Draw a graph using the collected historical transmission power of 5G communication base stations and the signal coverage distances at different transmission powers, with the transmission power as the independent variable and the signal coverage distance as the variable; use the least squares method to calculate the linear regression function of the transmission power and the signal coverage distance, and use the calculated linear regression function as the distance power function of the base station L = a1 × G + b1, where a1 represents the slope of the distance power function, and b1 represents the intercept of the distance power function.

[0071] By analyzing the transmission power and signal coverage distance of the base station in history, the relationship function between the transmission power and the signal coverage distance is obtained by linear regression calculation. The relationship function can clearly reflect the changing relationship between the transmission power and the signal coverage distance, and the signal coverage distance can be controlled by controlling the transmission power of the base station.

[0072] S200, collecting the heating rate of the 5G communication base station at different transmission powers in history to calculate the power heating function, collecting the cooling rate in the base station when natural ventilation without using cooling equipment in history, and calculating the ventilation cooling rate in the base station; collecting the temperature in the base station when the base station is cooled in history, and calculating the cooling threshold in the base station;

[0073] The specific steps for calculating the power heating function, ventilation cooling rate and cooling threshold are as follows:

[0074] S201, collect the heating rates of 5G communication base stations at different transmission powers in history, and assume that the collected heating rates at different transmission powers are {Fs1, Fs2, Fs3, ..., Fs m}, Fs1, Fs2, Fs3,..., Fs m represents the heating rate at the 1st, 2nd, 3rd, ..., mth transmission power in the base station in the collected history, where m is a positive integer; the transmission power in the base station collected in S101 is used as the independent variable, and the collected heating rate is used as the variable to draw a curve graph, and the linear regression curve of the transmission power and the heating rate is calculated using the same method as in S102, and the calculated linear regression function is used as the power heating function of the base station Fs=a2×G+b2, where a2 represents the slope of the power heating function, and b2 represents the intercept of the power heating function;

[0075] S202, collect the cooling rate in the base station when natural ventilation without using cooling equipment in the history {Zs1, Zs2, Zs3, ..., Zs k}, Zs1, Zs2, Zs3,..., Zs k Indicates the 1st, 2nd, 3rd, ..., kth cooling rate in the base station when natural ventilation without using cooling equipment in the collected history, k is a positive integer; the average value of the cooling rate of the base station during k natural ventilation is calculated as the ventilation cooling rate Ts of the base station, and the formula is: In the formula, k is the number of cooling rates in the base station during natural ventilation in the collected history;

[0076] S203, collecting the temperature in the base station when the base station is cooled down in the history {W1, W2, W3, ..., W j}, W1, W2, W3, ..., W j It represents the temperature inside the base station when the base station is subjected to the 1st, 2nd, 3rd, ..., jth cooling treatment in the collected history; the cooling threshold of the base station is calculated by the average value and the standard deviation, and the formula is: Wy=Wp-st_w, where Wp represents the average value of j temperatures in the collected history, st_w represents the standard deviation of j temperatures in the collected history, and Wy represents the cooling threshold of the base station.

[0077] The greater the transmission power of the base station during operation, the faster the heating rate of the device will be. Therefore, the calculated transmission power and heating rate can clearly show the relationship between the transmission power and heating rate of the base station. When the temperature of the base station is too high and the base station is cooled down, the transmission power can be controlled to reduce the heating rate of the base station to achieve the purpose of cooling.

[0078] S300, pairing adjacent base stations to form a base station pair, collecting real-time temperatures of two base stations in the base station pair, using the base station that needs to be cooled as the cooling base station in the base station pair, and using the other base station as a replacement base station, and using the cooling threshold to determine whether a single base station in the base station pair needs to be cooled;

[0079] The specific steps of using the temperature reduction threshold to determine whether a single base station in the same base station pair needs to be cooled are as follows:

[0080] S301, collect the geographical location of the base station, pair the two nearest adjacent base stations to form a base station pair, collect the real-time temperatures of the two base stations in the base station pair in real time, which are Ws1 and Ws2 respectively, and use the cooling threshold to judge the real-time temperatures of the two base stations collected in real time. When Ws≥Wy, it is judged that the corresponding base station needs to be cooled, and the base station that needs to be cooled is used as the cooling base station Pj in the base station pair. When Ws<Wy, it is judged that the corresponding base station does not need to be cooled, and the base station that does not need to be cooled is used as the replacement base station Pd in ​​the base station pair; Ws∈{Ws1, Ws2}, Ws represents the real-time temperature of the two base stations in the base station pair;

[0081] S302. After determining the cooling base station and the replacement base station of the same base station pair, the determined same base station pair is constructed as (Pj, Pd). The calculated cooling threshold is used to determine the real-time temperature of the base station, and the temperature of the base station can be automatically monitored to avoid abnormal operation of the base station due to excessive temperature, thereby reducing the probability of abnormality of the base station.

[0082] S400, when it is determined that equipment cooling is required in a single base station, real-time transmission power of two base stations in the same base station pair is collected in real time, and the same coverage distance in the same base station pair is calculated using a distance power function, and finally the power reduction amount of the cooling base station is calculated;

[0083] The specific steps for calculating the amount of power that can be reduced for cooling base stations are:

[0084] S401. When it is determined that equipment cooling is required in a single base station, the real-time transmission powers of two base stations in the same base station pair are collected in real time, which are Gj and Gd respectively. The relative distance between two adjacent base stations in the same base station pair is calculated as Lx using the distance formula between two points. The collected real-time transmission powers of adjacent base stations in the same base station pair are substituted into the distance power function, and the formula is:

[0085] Lj=a1×Gj+b1

[0086] Ld=a1×Gd+b1

[0087] In the formula, Lj represents the signal coverage distance of the cooling base station, and Ld represents the signal coverage distance of the replacement base station; the same coverage distance within the same base station pair is calculated using the signal coverage distance and relative distance of two base stations in the same base station pair, and the formula is: Lt = Lj + Ld - Lx, where Lt represents the calculated same coverage distance within the same base station pair;

[0088] S402, substituting the calculated same coverage distance within the same base station pair into the distance power function, and calculating the amount of power that can be reduced for the cooling base station, the formula is: In the formula, Gk represents the calculated amount of power reduction that can be achieved in the cooling base station.

[0089] In order to ensure the user's signal, when adjusting the transmission power of the base station, it is necessary to ensure that there is still signal coverage within the adjusted distance. Therefore, the same coverage distance of adjacent base stations is the adjustable range of the signal coverage distance of the base station. The adjustment amount of the transmission power is calculated according to the adjustment range of the signal coverage distance. Within the adjustment amount, the user's signal strength is guaranteed, and the purpose of cooling can be achieved by reducing the transmission power of the base station and reducing the heating rate.

[0090] S500, using the collected real-time transmission power of the cooling base station within the same base station to calculate the real-time heating rate, compare the real-time heating rate with the ventilation cooling rate, and calculate the required power reduction amount of the cooling base station;

[0091] The specific steps for calculating the required power reduction of the cooling base station are:

[0092] S501, substituting the real-time transmission power of the cooling base station collected in S401 into the power heating function of the base station to calculate the real-time heating rate, the formula is:

[0093] Fsj=a2×Gj+b2

[0094] In the formula, Fsj represents the calculated real-time heating rate of the cooling base station;

[0095] S502, using the ventilation cooling rate to determine the real-time heating rate, when Fsj>Ts, determine that the cooling base station needs cooling equipment for cooling, when Fsj≤Ts, determine that the cooling base station does not need cooling equipment for cooling; when it is determined that the cooling base station needs to use cooling equipment for cooling, calculate the difference between the real-time heating rate and the ventilation cooling rate, the formula is: Fc=Fsj-Ts, in the formula, Fc represents the calculated difference between the real-time heating rate and the ventilation cooling rate; substitute the calculated difference into the power heating function of the base station to calculate the required power reduction of the cooling base station, the formula is: In the formula, Gx represents the calculated required power reduction of the cooling base station.

[0096] The real-time heating rate is obtained by calculating the real-time transmission power of the base station. When the real-time heating rate is greater than the ventilation cooling rate, the temperature inside the base station can only be reduced by using cooling equipment.
