Description

Air conditioning control method, device, equipment and storage medium

Technical Field

The present application relates to the field of air conditioning technology, and in particular to an air conditioning control method, device, equipment and storage medium.

Background technique

With the rapid development of information technology, the number of communication equipment in the communication room is increasing. As the number of communication equipment continues to increase, the heat generated by the communication equipment is also gradually increasing, which leads to higher and higher temperatures in the communication room.

In response to the green and low-carbon development concept, heat pipe air conditioners have been widely used in scenarios such as operators, communication rooms, and data centers due to their own advantages. However, the technical solutions currently used by heat pipe air conditioner products often set a fixed temperature switching point, that is, when the outdoor temperature is lower than a certain set temperature value, the heat pipe mode is turned on to achieve energy saving and emission reduction. However, due to the differences in room loads in different scenarios, setting a fixed temperature switching point causes the heat pipe air conditioner to be unable to adapt to the temperature changes caused by changes in room loads, which in turn causes the operation and energy efficiency of the heat pipe air conditioner to fail to reach the optimal value.

Summary of the invention

The present application provides an air conditioning control method, device, equipment and storage medium, which improve the energy efficiency of the air conditioner while ensuring the cooling demand of the communication room.

In order to achieve the above purpose, this application adopts the following technical solutions:

In a first aspect, an air conditioning control method is provided, the method comprising: an air conditioning control device operates the air conditioning with a first cooling strategy when the temperature difference is greater than or equal to a temperature switching point; and operates the air conditioning with a second cooling strategy when the temperature difference is less than the temperature switching point and greater than a first threshold. The temperature difference is the difference between the indoor temperature and the outdoor temperature of the communication room, the first cooling strategy is to operate the heat pipe mode, and the second cooling strategy is to operate the heat pipe mode and the compressor mode. When the indoor temperature is greater than or equal to the second threshold, the air conditioning control device adjusts the temperature switching point based on a third threshold, and the adjusted temperature switching point is greater than the temperature switching point before the adjustment. When the indoor temperature is less than the second threshold, the air conditioning control device adjusts the temperature switching point based on the third threshold, and the adjusted temperature switching point is less than the temperature switching point before the adjustment.

In the air conditioning control method provided in the present application, when the indoor temperature is greater than or equal to the second threshold value, it indicates that the current air conditioning operation mode cannot meet the cooling demand of the communication room, so the temperature switching point is increased so that the temperature difference is more likely to fall within the interval greater than the first threshold value and less than the temperature switching point, and the heat pipe mode and the compressor mode are operated simultaneously to cool the communication room. When the indoor temperature is less than the second threshold value, it indicates that the current air conditioning operation mode can meet the cooling demand of the communication room, so the temperature switching point is reduced so that the temperature difference is more likely to fall within the interval greater than the temperature switching point, and the heat pipe mode is operated to cool the communication room. It can ensure that when the temperature difference is greater than or equal to the temperature switching point, running the air conditioner in the heat pipe mode can meet the cooling demand of the communication room, while ensuring the cooling demand of the communication room, the energy efficiency of the air conditioner is improved.

In this design, when the temperature difference is less than the first threshold value, it means that the air conditioning operating in the heat pipe mode cannot achieve efficient cooling. Therefore, in order to meet the cooling demand of the communication room, the air conditioning control device starts the compressor mode of the air conditioning and operates the air conditioning to ensure the cooling of the communication room and avoid excessively high indoor temperature, which affects the performance of the equipment in the communication room.

The air conditioning control device turns off the air conditioning when the indoor temperature is less than or equal to the fourth threshold value. In this design, when the air conditioning control device operates the air conditioning with the second cooling strategy, if the indoor temperature of the communication room has dropped below the second threshold value, the compressor mode is periodically operated to ensure the cooling demand of the communication room while reducing the energy consumption of the air conditioning; if the indoor temperature of the communication room has dropped below the fourth threshold value, the air conditioning is turned off to avoid the waste of air conditioning energy consumption caused by the continuous operation of the air conditioning when the communication room no longer needs to be cooled.

In a possible design, the air conditioning control device adjusts the temperature switching point based on the third threshold value, including: when the adjusted temperature switching point is greater than the upper limit of the preset temperature interval, the air conditioning control device determines the upper limit of the preset temperature interval as the adjusted temperature switching point. When the adjusted temperature switching point is less than the lower limit of the preset temperature interval, the air conditioning control device determines the lower limit of the preset temperature interval as the adjusted temperature switching point. In this design, by setting a preset temperature interval, when the temperature switching point is increased, if it exceeds the upper limit of the preset temperature interval, the upper limit of the preset temperature interval is determined as the temperature switching point, and the temperature switching point can be limited to a reasonable range. By setting a preset temperature interval, when the temperature switching point is reduced, if it exceeds the lower limit of the preset temperature interval, the lower limit of the preset temperature interval is determined as the temperature switching point, and the temperature switching point can be limited to a reasonable range. It can achieve the goal of improving the energy efficiency of the air conditioner while ensuring the cooling demand of the communication room.

The air conditioning control device includes a processing unit. The processing unit is used to adjust the temperature switching point based on a third threshold when the indoor temperature is greater than or equal to the second threshold, and the adjusted temperature switching point is greater than the temperature switching point before adjustment. The processing unit is also used to adjust the temperature switching point based on the third threshold when the indoor temperature is less than the second threshold, and the adjusted temperature switching point is less than the temperature switching point before adjustment.

In a possible design, the processing unit is also used to operate the air conditioner with a third refrigeration strategy when the temperature difference is less than or equal to the first threshold, and the third refrigeration strategy is to operate the compressor mode.

In a possible design, the processing unit is further used to operate the air conditioner with a fourth cooling strategy when the indoor temperature is greater than a fourth threshold value and less than the second threshold value, the fourth cooling strategy being to operate the heat pipe mode and periodically operate the compressor mode according to a preset cycle.

In response to the green and low-carbon development concept, heat pipe air conditioners have been widely used in scenarios such as operators, communication rooms, and data centers due to their own advantages. However, the technical solutions currently used by heat pipe air conditioner products often set a fixed temperature switching point, that is, when the outdoor temperature is lower than a certain set temperature value, the heat pipe mode is turned on to achieve energy saving and emission reduction. However, due to the differences in room loads in different scenarios, setting a fixed temperature switching point causes the heat pipe air conditioner to be unable to adapt to the temperature changes caused by changes in room loads, which in turn causes the operation and energy efficiency of the heat pipe air conditioner to fail to reach the optimal value.

In order to solve the above problems, the present application proposes an air conditioning control method, device, equipment and storage medium, which are used to operate the air conditioner with a first cooling strategy when the temperature difference is greater than or equal to the temperature switching point; and operate the air conditioner with a second cooling strategy when the temperature difference is less than the temperature switching point and greater than the first threshold. The temperature difference is the difference between the indoor temperature and the outdoor temperature of the communication room. The first cooling strategy is to operate the heat pipe mode, and the second cooling strategy is to operate the heat pipe mode and the compressor mode. The air conditioning control method includes: the air conditioning control device adjusts the temperature switching point based on a third threshold when the indoor temperature is greater than or equal to the second threshold, and the adjusted temperature switching point is greater than the temperature switching point before the adjustment. The air conditioning control device adjusts the temperature switching point based on the third threshold when the indoor temperature is less than the second threshold, and the adjusted temperature switching point is less than the temperature switching point before the adjustment.

In this way, when the indoor temperature is greater than or equal to the second threshold, it indicates that the current air-conditioning operation mode cannot meet the cooling demand of the communication room, so the temperature switching point is increased so that the temperature difference is more likely to fall in the interval greater than the first threshold and less than the temperature switching point, and the heat pipe mode and the compressor mode are operated simultaneously to cool the communication room. When the indoor temperature is less than the second threshold, it indicates that the current air-conditioning operation mode can meet the cooling demand of the communication room, so the temperature switching point is reduced so that the temperature difference is more likely to fall in the interval greater than the temperature switching point, and the heat pipe mode is operated to cool the communication room. The air-conditioning control method provided in the present application can ensure that when the temperature difference is greater than or equal to the temperature switching point, operating the air-conditioning in the heat pipe mode can meet the cooling demand of the communication room, while ensuring the cooling demand of the communication room, the energy efficiency of the air-conditioning is improved.

FIG1 shows an air conditioning control system. The air conditioning control method provided in the embodiment of the present application can be applied to the air conditioning control system shown in FIG1 , and is used to improve the energy efficiency of the air conditioning while ensuring the cooling demand of the communication room. As shown in FIG1 , the air conditioning control system 10 includes an air conditioning control device 11, an air conditioner 12, and a temperature acquisition device 13.

Among them, the air conditioning control device 11 is connected to the air conditioner 12 and the temperature collection device 13 respectively. In the above connection relationship, wired connection can be adopted, and wireless connection can also be adopted, which is not limited in the embodiment of the present application.

The air conditioning control device 11 can be used to obtain the indoor temperature and outdoor temperature of the communication room collected from the temperature collection device 13. Further, the air conditioning control device 11 can be used to determine the difference between the indoor temperature and the outdoor temperature as the temperature difference according to the indoor temperature and the outdoor temperature of the communication room.

The air conditioning control device 11 can also be used to operate the air conditioning in a first cooling strategy when the temperature difference is greater than or equal to the temperature switching point, wherein the first cooling strategy is to operate the heat pipe mode.

The air conditioning control device 11 can also be used to operate the air conditioning in a second cooling strategy when the temperature difference is less than the temperature switching point and greater than the first threshold, wherein the second cooling strategy is to operate the air conditioning in a heat pipe mode and a compressor mode.

The air conditioning control device 11 can also be used to adjust the temperature switching point based on the third threshold value when the indoor temperature is greater than or equal to the second threshold value. The adjusted temperature switching point is greater than the temperature switching point before the adjustment, so that the temperature difference is more likely to fall within the range greater than the first threshold value and less than the temperature switching point, and the air conditioning is operated with the second cooling strategy to meet the cooling demand of the communication room.

The air conditioning control device 11 can also be used to adjust the temperature switching point based on the third threshold value when the indoor temperature is less than the second threshold value. The adjusted temperature switching point is less than the temperature switching point before adjustment, so that the temperature difference is more likely to fall within a range greater than or equal to the temperature switching point, and the air conditioning is operated with the first cooling strategy, thereby ensuring the cooling demand of the communication room while improving the energy efficiency of the air conditioning.

The air conditioner 12 includes an outdoor air conditioner unit and an indoor air conditioner unit.

Among them, the air conditioner outdoor unit is mainly composed of a condenser assembly, a fan assembly and a compressor assembly, etc., which mainly realizes heat exchange with the external environment.

The indoor unit of the air conditioner is mainly composed of a first evaporator assembly, a second evaporator assembly and a fan assembly.

It should be noted that the first evaporator assembly and the second evaporator assembly can be placed front to back, left to right, or upward. According to the airflow direction, the first evaporator assembly is located at the rear end of the second evaporator assembly, that is, the airflow first passes through the second evaporator and then passes through the first evaporator assembly. The structural form of the first evaporator assembly and the second evaporator assembly can be flat or U-shaped, and the embodiments of the present application do not specifically limit this.

Among them, the first evaporator assembly, the compressor, the air-conditioning outdoor unit and accessories constitute the first circulation system, and the first circulation system mainly realizes the air-conditioning in the compressor mode.

The second evaporator assembly, the air conditioner outdoor unit and accessories constitute the second circulation system, and the second circulation system mainly realizes the air conditioner running in the heat pipe mode.

The air conditioner 12 can be used to implement a cooling strategy in a compressor mode, a cooling strategy in a heat pipe mode, or a cooling strategy in both a compressor mode and a heat pipe mode.

The temperature acquisition device 13 includes an indoor temperature acquisition module and an outdoor temperature acquisition module.

Among them, the indoor temperature acquisition module can be deployed on the outside of the air conditioner indoor unit to detect the indoor temperature; the outdoor temperature acquisition module can be deployed on the outside of the air conditioner outdoor unit to detect the outdoor temperature.

The temperature collection device 13 can be used to send the collected indoor temperature and outdoor temperature of the communication room to the air conditioning control device 11, so that the air conditioning control device 11 controls the air conditioner 12 according to the indoor temperature and outdoor temperature, thereby ensuring the cooling demand of the communication room and improving the energy efficiency of the air conditioner.

FIG2 is a flow chart of an air conditioning control method according to some exemplary embodiments. In some embodiments, the air conditioning control method can be applied to the air conditioning control device 11 in the air conditioning control system 10 as shown in FIG1 . Hereinafter, the air conditioning control method is described by taking the application of the air conditioning control method to the air conditioning control device 11 as an example.

As shown in FIG. 2 , the air conditioning control method provided in the embodiment of the present application includes the following S201 - S207 .

S201. The air conditioning control device obtains the indoor temperature and outdoor temperature of the communication room.

As a possible implementation, the temperature acquisition device detects the indoor temperature and outdoor temperature of the communication room in real time and sends the temperature information to the air conditioning control device. Correspondingly, the air conditioning control device receives the temperature information sent by the temperature acquisition device and obtains the indoor temperature and outdoor temperature of the communication room.

It should be noted that the temperature acquisition device can synchronize the temperature information to the air-conditioning control device in real time, or it can periodically send temperature information to the air-conditioning control device according to a preset temperature synchronization period. For example, the preset temperature synchronization period can be 5 seconds, 10 seconds, etc., and the embodiments of the present application do not make specific limitations on this.

S202: The air conditioning control device determines a temperature difference.

As a possible implementation manner, after acquiring the indoor temperature and outdoor temperature of the communication room, the air conditioning control device calculates the difference between the indoor temperature and the outdoor temperature, and determines the calculated difference as the temperature difference.

S203: The air conditioning control device operates the air conditioning with a first cooling strategy when the temperature difference is greater than or equal to the temperature switching point.

Among them, the first cooling strategy is to operate the heat pipe mode.

As a possible implementation, after determining the temperature difference, the air conditioning control device determines the relationship between the temperature difference and the temperature switching point. Further, when the temperature difference is greater than or equal to the temperature switching point, the air conditioning control device selects the first cooling strategy to operate the air conditioner and starts the heat pipe mode of the air conditioner.

It can be understood that the greater the temperature difference between indoor temperature and outdoor temperature, the better the cooling effect brought by the air conditioner operating in heat pipe mode. Therefore, when the temperature difference is greater than the temperature switching point, the air conditioner control device chooses to start the heat pipe mode of the air conditioner and operates the air conditioner with the first cooling strategy. This can improve the energy efficiency of the air conditioner while bringing better cooling effect.

S204: The air conditioning control device operates the air conditioning with a second cooling strategy when the temperature difference is less than the temperature switching point and greater than the first threshold.

The second cooling strategy is to operate the heat pipe mode and the compressor mode.

As a possible implementation, after determining the temperature difference, the air conditioning control device determines whether the temperature difference is less than the temperature switching point and greater than the first threshold. Further, when the temperature difference is less than the temperature switching point and greater than the first threshold, the air conditioning control device selects the second cooling strategy to operate the air conditioner and starts the heat pipe mode and the compressor mode of the air conditioner.

It should be noted that the first threshold value can be set in advance in the air-conditioning control device by the operation and maintenance personnel of the air-conditioning control system. For example, since in the heat pipe mode, cooling can be achieved as long as there is a temperature difference between the indoor temperature and the outdoor temperature, the first threshold value can be 1 degree Celsius. Compared with the higher temperature difference value set in the prior art, the working time of the heat pipe mode is increased and the energy efficiency of the air conditioner is improved.

It is understandable that the smaller the temperature difference between indoor and outdoor temperatures, the worse the cooling effect brought by the air conditioner running in heat pipe mode. Therefore, in order to ensure the cooling demand of the communication room, the air conditioning control device chooses to start the heat pipe mode and compressor mode of the air conditioner. The air conditioner runs in compressor mode to supplement the cooling capacity that the heat pipe mode cannot provide. Although the heat pipe mode provides limited cooling capacity, it can still reduce the consumption required for cooling by the compressor mode. At the same time, the total energy consumption of running the heat pipe mode and the compressor mode is less than the energy consumption of running only the compressor mode, thereby achieving the goal of improving the energy efficiency of the air conditioner while ensuring the cooling demand of the communication room.

S205: The air conditioning control device determines the magnitude relationship between the indoor temperature and the second threshold.

As a possible implementation manner, after acquiring the indoor temperature of the communication room, the air conditioning control device determines the magnitude relationship between the indoor temperature and the second threshold value based on a preset second threshold value.

It should be noted that the second threshold is the design ambient temperature of the communication room. The temperature indicated by the second threshold is a temperature value pre-set in the air-conditioning control device by the operation and maintenance personnel of the air-conditioning control system after comprehensively considering the temperature resistance of the equipment in the room and the performance of the equipment. When the indoor temperature of the communication room exceeds the temperature indicated by the second threshold, it will affect the performance of the equipment in the communication room. The embodiment of the present application does not specifically limit the specific setting size of the second threshold.

S206: When the indoor temperature is greater than or equal to the second threshold, the air conditioning control device adjusts the temperature switching point based on the third threshold.

The temperature switching point after adjustment is greater than the temperature switching point before adjustment.

As a possible implementation method, the air-conditioning control device calculates the sum of the temperature switching point and the third threshold value based on the relationship between the indoor temperature and the second threshold value determined in the above step S205, and determines the calculated sum as the adjusted temperature switching point when the indoor temperature is greater than the second threshold value.

It should be noted that the third threshold value can be set in advance in the air-conditioning control device by the operation and maintenance personnel of the air-conditioning control system, and the embodiment of the present application does not specifically limit this.

In some embodiments, in order to prevent the air conditioning control device from adjusting the temperature point due to sudden fluctuations in the indoor temperature, the air conditioning control device is used to calculate the sum of the temperature switching point and the third threshold when it is determined that the indoor temperature is greater than or equal to the second threshold at each moment within a preset time period, and determine the calculated sum as the adjusted temperature switching point.

It is understandable that when the indoor temperature is greater than or equal to the second threshold, it indicates that the current air-conditioning operation mode cannot guarantee the cooling demand of the communication room. By increasing the temperature switching point, the judgment condition for the air-conditioning control device to select the second cooling strategy is easier to achieve, and the communication room is cooled by operating the heat pipe mode and the compressor mode at the same time. The air-conditioning control method provided in the embodiment of the present application can achieve the situation that the heat pipe mode alone cannot meet the cooling demand of the communication room. By adjusting the temperature switching point, the air-conditioning control device controls the air-conditioning to run in the heat pipe mode and the compressor mode at the same time to meet the cooling demand of the communication room.

S207: When the indoor temperature is lower than the second threshold, the air conditioning control device adjusts the temperature switching point based on the third threshold, and the adjusted temperature switching point is lower than the temperature switching point before the adjustment.

The temperature switching point after adjustment is smaller than the temperature switching point before adjustment.

As a possible implementation method, the air-conditioning control device calculates the difference between the temperature switching point and the third threshold value based on the relationship between the indoor temperature and the second threshold value determined in the above step S205, when the indoor temperature is lower than the second threshold value, and determines the calculated difference as the adjusted temperature switching point.

In some embodiments, in order to prevent the air conditioning control device from adjusting the temperature point due to sudden fluctuations in the indoor temperature, the air conditioning control device is used to calculate the difference between the temperature switching point and the third threshold when it is determined that the indoor temperature is less than the second threshold at each moment within a preset time period, and determine the calculated difference as the adjusted temperature switching point.

It can be understood that when the indoor temperature is lower than the second threshold, it means that the current air-conditioning operation mode can meet the cooling demand of the communication room. By lowering the temperature switching point, the judgment condition for the air-conditioning control device to select the first cooling strategy is easier to achieve. The air-conditioning operating in the heat pipe mode can meet the cooling demand of the communication room. At the same time, only running the heat pipe mode reduces the energy consumption of the air-conditioning and improves the energy efficiency of the air-conditioning.

In the air conditioning control method provided in the embodiment of the present application, the indoor temperature is detected, and it is further determined whether the indoor temperature can meet the temperature demand of the communication room, and then the temperature switching point is increased when the cooling demand of the communication room cannot be met, and the temperature switching point is reduced when the cooling demand of the communication room can be met. The air conditioning control device dynamically adjusts the temperature switching point according to the change of the heat dissipation load of the communication room, so that the cooling strategy of the air conditioner is dynamically matched with the actual application scenario, and the air conditioner can be operated in the most energy-saving way while ensuring the cooling demand of the communication room.

In one design, when the heat pipe air conditioner cannot achieve cooling, the air conditioning control method provided in the embodiment of the present application, as shown in FIG. 3 , also includes S301 - S302 .

S301. An air conditioning control device determines a magnitude relationship between a temperature difference and a first threshold.

As a possible implementation manner, the air conditioning control device compares the temperature difference between the indoor temperature and the outdoor temperature of the communication room determined in the above step S202 with the first threshold to determine the magnitude relationship between the temperature difference and the first threshold.

S302: When the temperature difference is less than the first threshold, the air conditioning control device operates the air conditioning using a third cooling strategy.

The third refrigeration strategy is to operate the compressor mode.

As a possible implementation manner, after determining that the temperature difference is less than the first threshold, the air conditioning control device selects the third cooling strategy to operate the air conditioner and starts the compressor mode of the air conditioner.

It is understandable that when the temperature difference is less than the first threshold, it means that the air conditioner operating in the heat pipe mode cannot achieve efficient cooling. Therefore, in order to meet the cooling demand of the communication room, the air conditioning control device starts the compressor mode of the air conditioner and runs the air conditioner to ensure the cooling of the communication room and avoid excessively high indoor temperature, which may affect the performance of the equipment in the communication room.

In one design, when the air-conditioning control device operates the air-conditioning with the second cooling strategy, in order to ensure that the indoor temperature of the communication room can meet the cooling needs of the communication room, the air-conditioning control method provided in the embodiment of the present application, as shown in Figure 4, also includes S401-S402.

S401: When the indoor temperature is greater than a fourth threshold and less than a second threshold, the air conditioning control device operates the air conditioning using a fourth cooling strategy.

Among them, the fourth refrigeration strategy is to operate the heat pipe mode and periodically operate the compressor mode according to a preset cycle.

As a possible implementation, after the air conditioner is operated for a preset time period using the second cooling strategy, the air conditioner control device determines whether the indoor temperature is greater than the fourth threshold and less than the second threshold. Further, when the indoor temperature is greater than the fourth threshold and less than the second threshold, the air conditioner control device selects the fourth cooling strategy to operate the air conditioner, operates the heat pipe mode of the air conditioner, and periodically operates the compressor mode according to a preset cycle.

It should be noted that the fourth threshold is the design ambient low temperature value of the communication room, which is generally set to be at least 5 degrees Celsius lower than the second threshold. It can be set in advance in the air-conditioning control device by the operation and maintenance personnel of the air-conditioning control system. The embodiment of the present application does not make any specific limitation on this.

The preset period can be set in advance in the air-conditioning control device by the operation and maintenance personnel of the air-conditioning control system. An exemplary period may be 5 minutes, and this embodiment of the present application does not specifically limit this.

It can be understood that when the indoor temperature is greater than the fourth threshold and less than the second threshold, it indicates that the current air conditioner is operated with the second cooling strategy to achieve the temperature reduction of the communication room. For better energy-saving effect, the air conditioning control device operates the air conditioner with the fourth cooling strategy, saves the operation of the heat pipe mode, periodically operates the compressor mode, reduces the operating time of the compressor mode, so as to improve the energy efficiency of the air conditioner.

S402: When the indoor temperature is less than or equal to a fourth threshold, the air conditioning control device turns off the air conditioning.

As a possible implementation, the air conditioning control device determines whether the indoor temperature is less than or equal to the fourth threshold. Further, when the indoor temperature is less than or equal to the fourth threshold, the air conditioning control device determines that the current indoor temperature of the communication room does not need to be cooled, so the air conditioning is turned off.

In the air conditioning control method provided in the embodiment of the present application, when the air conditioning control device operates the air conditioner with the second cooling strategy, if the indoor temperature of the communication room has dropped below the second threshold, the compressor mode is periodically operated to ensure the cooling demand of the communication room while reducing the energy consumption of the air conditioner; if the indoor temperature of the communication room has dropped below the fourth threshold, the air conditioner is turned off to avoid the waste of air conditioning energy due to continuous operation of the air conditioner when the communication room no longer needs to be cooled.

In one design, in order to avoid the temperature switching point being too large or too small, the air conditioning control method provided in the embodiment of the present application, as shown in FIG. 5 , further includes S501 - S502 .

S501: When the adjusted temperature switching point is greater than the upper limit of the preset temperature range, the air conditioning control device determines the upper limit of the preset temperature range as the adjusted temperature switching point.

As a possible implementation, when the air conditioning control device adjusts the temperature switching point based on the third threshold value in the above step S206, after determining the adjusted temperature switching point, it is determined whether the adjusted temperature switching point is greater than the upper limit of the preset temperature interval. Further, when the adjusted temperature switching point is greater than the upper limit of the preset temperature interval, the air conditioning control device determines the upper limit of the preset temperature interval as the adjusted temperature switching point.

It should be noted that the preset temperature range is set in advance in the air-conditioning control device by the operation and maintenance personnel of the air-conditioning control system, and the embodiment of the present application does not make any specific limitation on this.

It is understandable that in order to avoid the temperature switching point from being continuously raised due to the excessive load of the equipment in the communication room in a short period of time, and then after the load returns to normal, the temperature switching point is too high, causing the air conditioning control device to run the compressor mode because the temperature difference is not greater than or equal to the temperature switching point, resulting in energy waste. By setting a preset temperature range, and when increasing the temperature switching point, if it exceeds the upper limit of the preset temperature range, the upper limit of the preset temperature range is determined as the temperature switching point, and the temperature switching point can be limited to a reasonable range to avoid the above situation.

S502: When the adjusted temperature switching point is less than the lower limit of the preset temperature range, the air conditioning control device determines the lower limit of the preset temperature range as the adjusted temperature switching point.

Among them, the lower limit of the preset temperature range is greater than the first threshold.

As a possible implementation, when the air conditioning control device adjusts the temperature switching point based on the third threshold value in the above step S207, after determining the adjusted temperature switching point, it is determined whether the adjusted temperature switching point is less than the lower limit of the preset temperature range. Further, when the adjusted temperature switching point is less than the lower limit of the preset temperature range, the air conditioning control device determines the lower limit of the preset temperature range as the adjusted temperature switching point.

It is understandable that in order to avoid the situation where the equipment in the communication room has a low load in a short period of time and generates less heat, the temperature switching point is continuously lowered. After the load increases, the temperature switching point is too low, causing the air conditioning control device to only run the heat pipe mode because the temperature difference is greater than or equal to the temperature switching point, which cannot guarantee the cooling demand of the communication room and affects the performance of the equipment in the communication room. By setting a preset temperature range and lowering the temperature switching point, if it exceeds the lower limit of the preset temperature range, the lower limit of the preset temperature range is determined as the temperature switching point, which can limit the temperature switching point to a reasonable range to avoid the above situation.

FIG6 is a flow chart of an air conditioning control method according to some exemplary embodiments. In some embodiments, the air conditioning control method can be applied to the air conditioning control device 11 in the air conditioning control system 10 as shown in FIG1 . Hereinafter, the air conditioning control method is described by taking the application of the air conditioning control method to the air conditioning control device 11 as an example.

As shown in FIG6 , the air conditioning control device first determines the relationship between the temperature difference between the indoor temperature and the outdoor temperature of the communication room and the first threshold and the temperature switching point. When the temperature difference is less than or equal to the first threshold, the air conditioning control device controls the air conditioning to operate the compressor mode;

When the temperature difference is greater than or equal to the temperature switching point, the air conditioning control device controls the air conditioning to operate in a heat pipe mode;

When the temperature difference is greater than the first threshold and less than the temperature switching point, the air conditioning control device first controls the air conditioning to operate in the heat pipe mode. Furthermore, when determining whether the indoor temperature is greater than the second threshold, the air conditioning control device controls the air conditioning to operate in the compressor mode to achieve simultaneous operation of the heat pipe and the compressor.

Furthermore, when the indoor temperature drops to a value greater than the fourth threshold value and less than the second threshold value, the air conditioning control device controls the air conditioning to maintain operation in the heat pipe mode and periodically operates the compressor mode.

When the indoor temperature drops to less than or equal to the fourth threshold, the air conditioning control device determines that the current communication room no longer needs to be cooled, and turns off the air conditioning.

The air conditioning control method provided in the embodiment of the present application can ensure that when the temperature difference is greater than or equal to the temperature switching point, operating the air conditioner in heat pipe mode can meet the cooling demand of the communication room, while ensuring the cooling demand of the communication room, while improving the energy efficiency of the air conditioner.
