Background

At present, for a deeper mine, the temperature inside the mine is generally increased due to various heat sources inside the mine and the non-circulation of air. In order to improve the working environment inside a mine and reduce the ambient temperature, a cooling system is usually installed inside the mine to achieve cooling.

Therefore, for any environment to be cooled, no practical situation of the environment to be cooled exists in the prior art, and feasible working parameters are selected to enable the cooling system to work so as to reduce the high temperature in the mine.

The cooling effect analysis method of the cooling system provided by the embodiment of the application can be applied to terminal devices such as a tablet computer, a notebook computer, a super-mobile personal computer (UMPC), a netbook and the like, and the embodiment of the application does not limit the specific types of the terminal devices.

Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a cooling effect analysis method of a cooling system according to an embodiment of the present application, where the method includes the following steps:

s101, terminal equipment determines a simulation environment to be cooled; the simulated environment is provided with a simulated cooling system which has the same working principle as the cooling system and a heat releasing device for releasing heat.

In one embodiment, the simulated environment is an environment provided with a simulated cooling system having the same working principle as the cooling system and a heat releasing device for releasing heat. The cooling system includes, but is not limited to, a water-cooling system, an air-cooling system, and an ice-cooling system. Wherein, the structure and the cooling principle of each cooling system are different. Therefore, the cooling capacity and the manufacturing cost of each cooling system are different.

Based on this, for any one of the cooling systems, to determine the actual cooling effect of the cooling system after being installed inside the mine, the worker can preset a simulated environment, and set a corresponding simulated cooling system in the simulated environment based on the working principle of the cooling system. And then, arranging heat releasing equipment for releasing heat in the simulated environment so as to analyze the cooling effect of the simulated cooling system based on the temperature change of the simulated environment when the simulated cooling system works. Therefore, the purpose of analyzing the cooling effect of the cooling system is achieved. The terminal equipment needs to establish communication connection with each equipment in the simulation environment so as to acquire data.

Specifically, referring to fig. 2, the simulated cooling system may be a water-cooled cooling system, which mainly delivers the cooling water in the first cooling water pool 1 to the water-cooled refrigerating unit 4 through the first water pump 2 and the heat insulation pipeline 3. Then, the water-cooled refrigerator group 4 treats the cooling water to produce chilled water (3 ℃). Then, the chilled water is delivered into the air cooler 6 by the second water pump 5. The chilled water is further cooled by an air cooler 6 to obtain a cooling air flow. And then, the air cooler conveys the cooling air flow to the inside of the simulation environment, so that the cooling air flow and high-temperature and high-humidity air in the simulation environment are subjected to heat exchange, and the temperature and humidity in the simulation environment are reduced. In this embodiment, the simulated environment includes an exothermic device that can be used to release heat. Such as the electric heater 7 in fig. 2.

Wherein, the refrigerating medium of the water-cooled refrigerating unit 4 can transfer cold energy to the refrigerating fluid-chilled water (the lowest temperature can be 3 ℃) contained in the water-cooled refrigerating unit 4 through throttling expansion after being compressed by the compressor. Then, the heat generated by the water-cooled refrigerator group 4 is transferred to the cooling water by the condenser in the water-cooled refrigerator group 4. Then, the cooling water having received the heat flows into the second cooling water tank 8 through the heat-insulating pipe 3. Finally, the cooling water in the second cooling water pool 9 is discharged through a water discharge pipe 9, or is conveyed to the first cooling water pool 1 through a communication pipe 10 for recycling. The cooling water in the first cooling water pool 1 can be supplemented by a water supplementing pipe 11.

In addition, the above-mentioned simulation cooling system is used for carrying on the in-process that the cooling water carried, and the heat preservation insulated pipe 3 between first cooling water pond 1 and the water-cooled refrigerating unit 4 includes: a first water pump 2, a first flow meter 12 and a first temperature meter 13. The heat-insulating pipeline 3 between the water-cooled refrigerating unit 4 and the air cooler 3 comprises a second water pump 5, a second flowmeter 14 and a second thermometer 15. The simulated cooling system is used for discharging cooling water, and the heat-insulating pipeline 3 between the second cooling water pool 9 and the water-cooled refrigerating unit 4 comprises a third thermometer 16; the heat preservation and insulation pipeline 3 between the water-cooled refrigerating unit 4 and the air cooler 3 comprises a fourth thermometer 17. The first water pump 2 is used for adjusting the cooling water flow of the cooling water in the heat-insulating pipeline 3, and the first flowmeter 12 is used for detecting the actual value of the cooling water flow; the second water pump 5 is used for adjusting the chilled water flow of the chilled water in the heat-insulating pipeline 3, and the second flowmeter is used for detecting the actual value of the chilled water flow. The first thermometer 13, the second thermometer 15, the third thermometer 16, and the fourth thermometer 17 are used to detect the temperature of the cooling water in each heat-insulating duct 3.

It should be noted that, the above-mentioned multiple devices should all establish wireless connection with the terminal device, so that the terminal device can obtain corresponding cooling parameters, and analyze the cooling effect in the cooling system.

S102, the terminal equipment determines a plurality of cooling parameters for cooling in the simulation cooling system based on the working principle.

In an embodiment, the operation principle is explained in the above S101, and will not be described again. It is understood that, in the present embodiment, based on the first flowmeter 12, the second flowmeter 14, the first thermometer 13, the second thermometer 15, the third thermometer 16 and the fourth thermometer 17, the terminal device may use all the values collected by the above devices as the cooling parameters. Specifically, the temperature reduction parameters may include chilled water flow, cooling water flow, and temperature of cooling water in each thermal insulation pipeline, and may further include but are not limited to: the temperature and humidity of the simulated environment, the cold wind speed of the cooling wind flow generated by the air cooler, the wind quantity and the like are not limited.

S103, the terminal equipment adjusts the plurality of cooling parameters in sequence to obtain a plurality of cooling parameter combinations.

In an embodiment, for the plurality of cooling parameters, the terminal device may sequentially adjust the plurality of cooling parameters to preset cooling parameters. The preset cooling parameters refer to preset parameters of the cooling system during working. The plurality of preset cooling parameters after each adjustment are a cooling parameter combination, so that a plurality of cooling parameter combinations can be obtained.

For example, if the plurality of cooling parameters are the flow rate of the chilled water, the temperature of the chilled water and the cold wind speed of the cooling wind flow generated by the air cooler, the terminal device may first fix the flow rate of the chilled water to 12m³The cold wind speed of the cooling wind flow is 1.5 m/s. Under this condition, the temperature of the chilled water is gradually changed to gradually decrease the temperature of the chilled water. Based on the above, the terminal device can obtain a plurality of temperature reduction parameter combinations among the flow rate of the chilled water, the temperature of the chilled water and the cold wind speed of the cooling wind flow.

It should be noted that the above example is only one of the above examples, and does not limit the combination of the cooling parameters, and the present embodiment does not limit the combination of a plurality of cooling parameters.

S104, the terminal equipment obtains the parameter change of the thermal environment factors in the simulated environment when the simulated cooling system works under the combination of a plurality of cooling parameters.

In an embodiment, the combination of the plurality of cooling parameters is explained in the above S103, and will not be further described. It can be understood that, if the influence of a certain target cooling parameter on the cooling effect of the cooling system needs to be analyzed, the values of the other parameters in the cooling parameter combination should be kept unchanged, and only the value of the target cooling parameter is changed. And then, the terminal equipment controls the simulation cooling system to work in the cooling parameter combination to obtain the parameter change of the thermal environment factors in the simulation environment.

In an embodiment, the thermal environment factor in the simulated environment may be, but is not limited to, air temperature, air humidity, and the like in the simulated environment. It is understood that the temperature and humidity of the air can be collected by a temperature monitor and a humidity monitor, respectively, which will not be described in detail. The parameter variation can be a specific value corresponding to the temperature and the humidity of the air under each cooling parameter combination. Namely a temperature value and a humidity value.

And S105, the terminal equipment analyzes the cooling effect of the cooling system based on the parameter change and the cooling parameter combination.

In one embodiment, after determining the cooling parameter combination, the terminal device may establish a data table to record values between the cooling parameter combination and the parameter change. And then, determining target cooling parameters from the cooling parameter combination, and determining a temperature value or a humidity value corresponding to the simulated environment when the simulated cooling system works under different values of the target cooling parameters respectively.

For example, for the temperature reduction parameter combination in S103, which gradually changes the temperature of the chilled water, the temperature of the chilled water is gradually decreased. The temperature of the chilled water may be considered a target cooling parameter. Based on this, the terminal device may establish a data table between the target cooling parameter (temperature of chilled water) and the temperature of the simulated environment. Then, the terminal device can directly generate a curve with the horizontal axis as the temperature of the chilled water and the vertical axis as the temperature of the simulated environment based on the data table so as to analyze the relation between the target temperature reduction parameter (the temperature of the chilled water) and the temperature reduction effect of the temperature reduction system.

It should be noted that the operation principle between the simulated cooling system and the actual cooling system is the same. Therefore, when the terminal device analyzes the cooling effect of the simulation cooling system based on the parameter change and the cooling parameter combination, the terminal device analyzes the actual cooling effect.

In one embodiment, for any one cooling parameter combination, the simulated cooling system typically needs to operate for a predetermined period of time (e.g., ten minutes) at that cooling parameter combination. Then, the change of the temperature or humidity in the simulated environment within the preset time is obtained. Therefore, the temperature or humidity change condition can be used as the cooling effect of the cooling system under the combination of the cooling parameters. Furthermore, for the corresponding cooling effect under any one cooling parameter combination, the terminal device can determine the cooling parameter combination with the optimal cooling effect for cooling the simulated environment when the simulated cooling system works from the plurality of cooling parameter combinations.

In the embodiment, the simulated cooling system which has the same working principle as the cooling system and the heat releasing equipment for releasing heat are installed in the simulated environment to be cooled. Thereafter, a plurality of cooling parameters that can affect the cooling effect of the simulated cooling system are determined based on the operating principles. And then, adjusting each cooling parameter to obtain a plurality of cooling parameter combinations. And finally, the terminal equipment can control the parameter change of the thermal environment factors in the simulated environment when the simulated cooling system works under the combination of a plurality of cooling parameters. Furthermore, the terminal equipment can analyze the variation between the parameters of the plurality of cooling parameter combinations and the thermal environment factors so as to determine the optimal cooling effect of the cooling system when the cooling system works under which cooling parameter combination.

In an embodiment, referring to fig. 3, when the simulated cooling system is obtained at S104 and respectively operates under a plurality of cooling parameter combinations, the parameter change of the thermal environment factors in the simulated environment specifically includes the following sub-steps S1041-S1043, which are detailed as follows:

s1041, the terminal device determines a temperature test point in the simulation environment.

In an embodiment, the temperature test point may be a location where a temperature monitor is disposed in the simulation environment. The number of the temperature test points may be plural, which is not limited herein. It should be added that if the humidity change in the simulated environment needs to be monitored, a humidity monitor can be disposed at the same position as the temperature test point, which is not limited in this respect.

S1042, the terminal equipment acquires temperature change values of temperature test points when the simulation cooling system works under a plurality of cooling parameter combinations respectively; the value of at least one target temperature reduction parameter in the temperature reduction parameter combinations is changed.

In one embodiment, it has been described above that for any one cooling parameter combination, the simulated cooling system generally needs to operate at that cooling parameter combination for a predetermined period of time (e.g., ten minutes). Then, the change of the temperature or humidity in the simulated environment within the preset time is obtained. Based on this, the temperature variation value can be considered as the variation value of the temperature in the simulated environment after the simulated cooling system works for a preset time under each cooling parameter combination.

In an embodiment, the target cooling parameter is a cooling parameter with a changed value in a plurality of cooling parameter combinations. Specifically, reference may be made to the above explanation of the target cooling parameter in S105, which will not be described again.

S1043, the terminal device establishes a relation graph of the temperature change value and the target cooling parameter; the relational graph is used for analyzing the cooling effect of the cooling system.

In one embodiment, the relationship graph may be a two-dimensional line graph. Specifically, referring to fig. 4, fig. 4 is a two-dimensional line graph of a target temperature reduction parameter (chilled water temperature) and a temperature of a measurement point of a temperature measurement point in a simulation environment. Therefore, the terminal equipment can clearly and visually display the target cooling parameter and the temperature of the measuring point after generating the line graph between the target cooling parameter and the temperature of the measuring point, so that the staff can visually analyze the cooling effect of the cooling system based on the line graph.

In one embodiment, referring to fig. 5, the relationship graph is a two-dimensional line graph formed by the temperature variation value and the target temperature reduction parameter, and the two-dimensional line graph comprises a multi-segment broken line formed by the temperature variation value and the target temperature reduction parameter; when the simulated cooling system is obtained to work under a plurality of cooling parameter combinations respectively in S104, the parameter change of the thermal environment factors in the simulated environment specifically includes the following substeps S1044-S1046, which are detailed as follows:

s1044, respectively calculating the slopes of the multi-section broken lines by the terminal equipment according to the target cooling parameter value and the temperature change value in the two-dimensional broken line graph; the slope is used for indicating that when the target temperature reduction parameter value in each broken line changes, the corresponding temperature changes rapidly and slowly.

In an embodiment, the two-dimensional line drawing in S1043 is described, and specifically, the two-dimensional line drawing in fig. 5 may be referred to, which is not described in detail. In the above description, the horizontal axis represents the chilled water temperature, and based on this, the multi-segment broken line may be divided and determined based on the chilled water temperature.

For example, the terminal device may use the temperature of the measuring point corresponding to the temperature of the chilled water every preset temperature difference as a broken line. For example, taking fig. 4 as an example, fig. 4 includes 4 broken lines. Wherein, the first two sections of broken lines are respectively arranged at intervals of 3 ℃ temperature difference, and the second two sections of broken lines are respectively arranged at intervals of 1 ℃ temperature difference. Specifically, fig. 4 includes a broken line corresponding to a chilled water temperature of 12 ℃ to 9 ℃, a broken line corresponding to a chilled water temperature of 9 ℃ to 6 ℃, a broken line corresponding to a chilled water temperature of 6 ℃ to 5 ℃, and a broken line corresponding to a chilled water temperature of 5 ℃ to 4 ℃.

Based on the temperature, the terminal equipment can calculate the slope of each section of the broken line based on the temperature of the measuring point corresponding to the end point of each section of the broken line. Illustratively, taking a polygonal line corresponding to the chilled water temperature of 12 ℃ to 9 ℃ as an example, the difference between a temperature measurement point corresponding to 12 ℃ and a temperature measurement point corresponding to 9 ℃ can be calculated, and then the ratio of the difference to the value 3 (the temperature difference between the chilled water temperature of 12 ℃ and 9 ℃) is calculated, so as to obtain the slope of the polygonal line corresponding to the chilled water temperature of 12 ℃ to 9 ℃. Since the horizontal axis in fig. 4 shows a gradual decrease in the value from left to right, the slope calculated in the last step should be positive. Based on the method, the terminal equipment can directly determine the corresponding temperature change speed when the target temperature reduction parameter value (the temperature of the chilled water) in each section of broken line changes according to the slope.

S1045, the terminal device determines a target slope representing the fastest temperature change and a target broken line corresponding to the target slope from the slopes.

S1046, the terminal device determines the plurality of target cooling parameter values corresponding to the target broken lines as the cooling parameter values with the optimal cooling effect.

In an embodiment, the calculation of the slope is described in the above S1044, which is not explained again. It will be appreciated that after determining the slope of each polyline, the maximum of the plurality of slopes may be determined as the target slope, and the polyline to which the target slope corresponds may be determined as the target polyline. Specifically, the fold line corresponding to the chilled water temperature of 6 ℃ to 5 ℃ and the fold line corresponding to the chilled water temperature of 5 ℃ to 4 ℃ in fig. 4 can be determined as the target fold line.

Based on the above, the terminal device can determine a plurality of target cooling parameter values corresponding to the target broken lines as the cooling parameter values with the optimal cooling effect. Namely, the terminal equipment can determine that when the temperature of the chilled water is less than 6 ℃, the cooling effect of the cooling system corresponding to the simulated environment is the most ideal.

In an embodiment, referring to fig. 6, the simulated cooling system further includes an air outlet for discharging hot air out of the simulated environment during operation; the target cooling parameters comprise the cold air speed of cold air generated by the simulation cooling system during working; fig. 6 shows a flowchart of an implementation of a cooling effect analysis method of a cooling system according to another embodiment of the present application, where the method includes the following steps:

s11, the terminal equipment determines the outlet air temperature at the air outlet when the simulation cooling system respectively generates cold air at a plurality of cold air speeds; the outlet air temperature is a thermal environmental factor outside the simulated environment.

In one embodiment, similar to the air-conditioning refrigeration equipment, the above-mentioned simulated cooling system also has an air outlet for discharging hot air. It will be appreciated that the outlet is typically located outside the simulated environment. Therefore, the terminal device can determine the outlet air temperature at the air outlet as a thermal environment factor other than the simulated environment, that is, different from the thermal environment factor in the simulated environment described in the above S104.

In an embodiment, the cold wind speed described in the above S102 may be one of a plurality of cooling parameters, and will not be described again.

It should be noted that the chilled water transfers the cooling energy to the wind flow in the air cooler to generate the wind flow with a lower temperature to exchange heat with the high-temperature air in the simulated environment. Therefore, it is considered that the wind speed of the air cooler is one of the important factors affecting the heat and moisture exchange efficiency of the air cooler and the air cooler. Based on this, the terminal device presets the temperature of the chilled water and the temperature of the cold wind flow generated by the air cooler. And then, changing the cold air speed of the cold air flow generated by the air cooler, and collecting the outlet air temperature at the outlet of the analog cooling system.

For example, the terminal device may set the temperature of the chilled water to 6 ℃, the temperature of the cold wind generated by the air cooler to a constant value of 18.8 ℃, and the data of the outlet wind temperature after changing the cold wind speed of the cold wind generated by the air cooler are shown in table 1 below:

TABLE 1 Outlet air temperature of simulation cooling system working at different cold air wind speeds

Wind speed of cold wind	1.5m/s	2.5m/s	3.5m/s	4.5m/s
					Outlet air temperature/° c	10.8	11.8	12.4	12.6

And S12, analyzing the cooling effect of the cooling system by the terminal equipment according to the multiple cold air speeds and the outlet air temperatures respectively corresponding to the multiple cold air speeds.

In an embodiment, in the step S11, table 1 is established according to a plurality of cold wind speeds and outlet wind temperatures respectively corresponding to the plurality of cold wind speeds, so as to analyze a cooling effect of the cooling system. Specifically, as can be seen from the data in table 1, the outlet air temperature of the simulated cooling system will increase with the increase of the air speed of the cool air. However, the heat exchange efficiency of the corresponding air cooler is reduced. Namely, the increasing trend of the outlet air temperature gradually becomes smaller along with the rising of the air speed of the cold air.

In an embodiment, referring to fig. 7, in step S12, analyzing the cooling effect of the cooling system according to the wind speeds of the cool wind and the outlet wind temperatures corresponding to the wind speeds of the cool wind, the method specifically includes the following substeps S121-S125, which are detailed as follows:

and S121, the terminal equipment determines the power consumption of the simulation cooling system when the cold air is generated at a plurality of cold air speeds in a preset time period.

In an embodiment, the preset time period may be set by a worker according to an actual situation, and is not limited thereto. Specifically, the preset time period may be set to ten minutes. When the simulation cooling system works under different cooling parameter combinations, the power consumption of the simulation cooling system is usually different during working. Therefore, the terminal equipment can collect the power consumption in the preset time period through the ammeter in advance when the simulation cooling system respectively generates cold air with a plurality of cold air wind speeds.

And S122, the terminal equipment generates a plurality of working parameter combinations according to the power consumption, the outlet air temperature, the temperature of the simulation environment and the cold air speed.

And S123, the terminal equipment establishes a decision matrix according to the combination of the working parameters.

And S124, the terminal equipment determines a target working parameter combination from the plurality of working parameter combinations according to the decision matrix.

In an embodiment, the decision matrix may be used to perform matrix operation on the values of the plurality of cooling parameters in each cooling parameter combination in the cooling system, so as to obtain an evaluation value of each cooling parameter combination. Specifically, a plurality of cooling parameters in the cooling parameter combination respectively include power consumption, outlet air temperature, the temperature of the simulated environment and cold air wind speed, and the decision matrix that it constructs specifically can be:

the Am is a parameter value of power consumption in the mth working parameter combination, the Bm is a parameter value of outlet air temperature in the mth working parameter combination, the Cm is a parameter value of environment simulation temperature in the mth working parameter combination, and the Dm is a parameter value of cold air speed in the mth working parameter combination.

In an embodiment, the above-mentioned working parameter combination is similar to the cooling parameter combination, and the difference is only that in this embodiment, the working parameter combination is composed of the above-mentioned power consumption, outlet air temperature, temperature of the simulated environment, and cold air speed.

It should be noted that, in this embodiment, only four cooling parameters that have a deep influence on the cooling effect are selected for the cooling parameters. It can be understood that the cooling parameters having an influence on the cooling effect are usually multiple, and if a decision matrix needs to be constructed for a plurality of cooling parameters, the rest of the cooling parameters can be written into the decision matrix respectively after the cold air speed D.

In an embodiment, after the terminal device establishes the decision matrix, normalization processing may be performed on parameter values of each cooling parameter in the decision matrix, so as to unify the dimension of the parameter value corresponding to each cooling parameter in each working parameter combination in the decision matrix. And then, calculating according to the parameter values to obtain a parameter evaluation value corresponding to each cooling parameter in each working parameter combination. And finally, weighting and summing the evaluation values of the parameters and the preset weight values to obtain the evaluation value in each working parameter combination.

Based on this, the terminal device can determine the maximum evaluation value from among the evaluation values in each operation parameter combination. And then, determining the working parameter combination corresponding to the maximum evaluation value as the target working parameter combination with the best cooling effect.

And S125, the terminal equipment determines the cooling effect of the simulation cooling system when cold air is generated at the target cold air speed as the target cooling effect.

In an embodiment, in the above S124, how to determine the target operation parameter combination with the best cooling effect based on the decision matrix, and thereby determine the cooling effect when the simulated cooling system generates cold wind by using the target operation parameter combination as the target cooling effect.

It should be noted that the power consumption is used to represent the economic cost that the simulation cooling system needs to consume under the corresponding working parameter combination, and the outlet air temperature, the temperature of the simulation environment, and the cold air speed are used to represent the efficiency of the simulation cooling system in cooling the interior of the simulation environment under the corresponding working parameter combination.

Based on this, it can be understood that, for the target cooling effect, it is the result of the terminal device processing the power consumption, the outlet air temperature, the temperature of the simulated environment, and the cold air speed in various cooling parameter combinations. The result may also be considered to be that the simulated cooling system may provide a more suitable target operating parameter set for the simulated cooling system after the purpose of cooling the interior of the simulated environment is achieved (e.g., the simulated cooling system may operate at a lower cost under the target operating parameter set). So that when the simulation cooling system can work under the combination of target working parameters, reasonable balance between cooling efficiency and cost can be achieved.

In an embodiment, referring to fig. 8, after analyzing the cooling effect of the cooling system according to the plurality of cold wind speeds and the outlet wind temperatures corresponding to the plurality of cold wind speeds at S12, the method specifically includes the following steps S13-S16, which are detailed as follows:

s13, the terminal equipment obtains the enthalpy value of air before cooling of heat contained in the simulated environment; wherein, the enthalpy value of the air is the total heat contained in the air.

And S14, the terminal equipment determines the air enthalpy value of the simulation environment after cooling based on the preset cooling temperature in the simulation environment.

In one embodiment, the enthalpy of the air is the total heat contained in the air, which can be determined based on an existing psychrometric chart of the air. Specifically, referring to fig. 9, the vertical axis is temperature, the horizontal axis is air moisture content, and the curve is corresponding air enthalpy. The humidity and the temperature in the air enthalpy value before cooling in the simulated environment can be acquired respectively according to the temperature measuring instrument and the humidity measuring instrument, and then the corresponding air enthalpy value is determined. The enthalpy value of the cooled air can also be determined according to the cooling standard (temperature and humidity which should be met after the temperature of the simulated environment is reduced) designed in advance by workers.

And S15, calculating the enthalpy value of the air before cooling and the enthalpy value of the air after cooling by the terminal equipment according to a preset energy balance equation to obtain the effective cooling distance of the simulation cooling system in the simulation environment.

In one embodiment, the energy balance equation described above is used to calculate the equation for the heat interaction occurring in the simulated environment. It can be understood that the cooling air flow treated by the air cooler is mixed with the untreated air flow in the simulated environment to form a mixed air flow, which is an air flow mixing process; the air flow needs to be continuously subjected to heat exchange in the air flow mixing process, and when the air flow reaches a certain distance, the temperature of the air flow rises. Therefore, the terminal equipment can calculate the effective distance of the cooling air flow generated by the simulation cooling system to cool the simulation environment based on the energy balance equation.

The preset energy balance equation may specifically be:

M1i1+(M-M1)i＝Mi_{mixing of}； (2)

Wherein M is the mass flow of air in the simulated environment, i is the air enthalpy value of the unit mass of the air flow which is not processed by the air cooler in the simulated environment, and i is the air enthalpy value of the unit mass of the mixed air flow in the simulated environment; k is an unstable heat exchange coefficient between air and cooling air flow in the simulated environment, U is a boundary perimeter of the simulated environment, L is an effective cooling distance of the simulated cooling system, T is an average temperature in the simulated environment before cooling, T1 is a temperature of untreated air flow in the simulated environment before mixing, T2 is a preset air temperature in the simulated environment after mixing, M1 is a mass flow rate of the cooling air flow, i1 is an air enthalpy value of unit mass of the cooling air flow, i is an air enthalpy value of unit mass of the mixed air flow, and Qe is other heat except for heat convection of the untreated air flow and the cooling air flow in the simulated environment.

It should be noted that the above formula for calculating the effective cooling distance is based on: the cooling air flow flowing out of the air cooler is mixed with untreated air flow in a simulated environment, the mixing is assumed to be in a turbulent steady state condition and is carried out under an adiabatic condition, and the condition of neglecting the change of the air flow energy and potential energy is obtained. However, the above-mentioned process of mixing the wind flows, and the variation of the wind flow energy and the potential energy are almost negligible in the actual process.

Therefore, the terminal device can consider that the effective cooling distance of the simulated cooling system in the simulated environment, which is obtained by calculation through the formula, is close to the actual cooling distance of the actual cooling system in the real mine environment.

And S16, the terminal equipment determines the installation place of the simulation cooling system in the simulation environment according to the effective cooling distance.

In an embodiment, determining the installation location of the simulated cooling system in the simulated cooling environment may be that, if the length of the space size of the simulated environment is much greater than the effective cooling distance, a plurality of simulated cooling systems should be installed in the simulated environment in order to effectively cool the simulated environment.

Specifically, the terminal device can calculate the ratio between the actual length and the effective cooling distance based on the actual length of the simulated environment, so as to obtain the installation number of the simulated cooling system. At this time, the installation distance of the plurality of simulated cooling systems installed in the simulated environment should be consistent with the effective cooling distance. Therefore, the terminal equipment can enable the simulation cooling system to effectively cool the simulation environment, and the installation quantity of the simulation cooling system can be reduced.

It will be appreciated that if there are fractional numbers in the ratio, the fractional numbers may be ignored and the integer portion of the ratio may be incremented by 1. Based on this, it can be considered that the installation distance between the finally installed simulated cooling system and the previously installed simulated cooling system can be smaller than the effective cooling distance.

In an embodiment, referring to fig. 10, after calculating the enthalpy value of the air before cooling and the enthalpy value of the air after cooling according to the preset energy balance equation to obtain the effective cooling distance of the simulated cooling system in the simulated environment at S15, the method specifically includes the following steps S151-S152, which are detailed as follows:

and S151, the terminal equipment calculates the installation number of the simulation cooling systems according to the space size and the effective cooling distance of the simulation environment.

S152, if the installation number of the terminal equipment is multiple, determining the effective cooling distance as the installation distance of the multiple simulation cooling systems installed in the simulation environment.

In an embodiment, the manner of calculating the installation number and the installation distance of the base simulation cooling system are already explained in the above S15, and will not be further explained.
