Description

Technical Field

[0001] This application relates to the field of environmental control, specifically to a method and system for controlling the fresh air cooling in a communication equipment room. Background Technology

[0002] Communication equipment rooms and base stations contain a large number of communication devices, which generate a lot of heat during operation. To ensure the normal operation of the equipment, the equipment rooms usually need to be cooled continuously throughout the year. According to statistics, air conditioning energy consumption accounts for about 40% to 60% of the total energy consumption of communication equipment rooms and base stations, making it the main power-consuming equipment in the equipment rooms. How to effectively reduce the air conditioning energy consumption of communication equipment rooms has become an important issue for communication operators to reduce carbon emissions, lower costs, and increase efficiency.

[0003] Currently, existing technologies have proposed a new air energy-saving system that utilizes outdoor natural cold sources to cool communication equipment rooms. When the outdoor temperature is lower than a set threshold, the system introduces outdoor cold air, which is then purified by an air filter and sent into the room to cool the equipment room, thereby reducing the operating time of the air conditioner.

[0004] However, the heat generated by equipment in communication equipment rooms is not constant but fluctuates frequently with changes in communication service load, resulting in large and rapid transient changes in the heat load of the equipment room. In practical applications, the aforementioned fresh air energy-saving system typically adopts a temperature threshold control strategy, that is, switching between fresh air mode and air conditioning mode based on the comparison between the indoor temperature and a set threshold. At this time, if the indoor temperature fluctuation caused by the fluctuation of communication service load is close to the set threshold, the system will cause the system to repeatedly switch between fresh air and air conditioning. During this process, the air conditioning compressor generates a lot of additional energy loss due to repeated start-stop and frequent speed adjustment, resulting in poor actual energy-saving effect. Summary of the Invention

[0005] To address the current problem of poor energy efficiency in communication equipment rooms, this application provides a fresh air cooling control method and system for communication equipment rooms.

[0006] In a first aspect, this application provides a method for controlling the ventilation and heat dissipation of a communication equipment room, applied in a ventilation and heat dissipation control system, the method comprising: The system obtains the current outdoor temperature, indoor temperature, operating mode, and the switching time of the nearest operating mode in the communication equipment room. The operating mode is either the air conditioning mode or the fresh air mode. When the outdoor temperature is less than or equal to a preset temperature threshold, the mode switching time interval between the current time and the nearest operating mode switching time is calculated. Calculate the mode switching temperature offset based on the mode switching time interval; Based on the mode switching temperature offset, determine the mode switching temperature threshold of the current operating mode; Based on the current indoor temperature and the mode switching temperature threshold, determine whether the operating mode switching conditions are met. If satisfied, output the operation mode switching instruction; If the conditions are not met, the current operating mode will be maintained.

[0007] Optionally, calculating the mode switching temperature offset based on the mode switching time interval specifically involves: Obtain the mode switching direction at the moment of the nearest neighbor's operating mode switching, the mode switching direction includes a first direction from the air conditioning mode to the fresh air mode, and a second direction from the fresh air mode to the air conditioning mode; If the nearest neighbor operation mode switching time is in the first direction, then the mode switching temperature offset is calculated based on the maximum allowable offset of the preset temperature recovery range of the communication equipment room, the minimum safe restart time interval of the air conditioner, and the mode switching time interval. If the nearest neighbor operation mode switching time is in the second direction, then obtain the historical mode switching time interval sequence within a preset time period before the current time; Calculate the coefficient of variation of the historical mode switching time interval sequence and use it as the oscillation coefficient; Based on the oscillation coefficient, the mode switching temperature offset in the first direction is corrected to obtain the mode switching temperature offset in the second direction.

[0008] Optionally, the step of calculating the mode switching temperature offset based on the maximum allowable offset of the preset temperature recovery range of the communication equipment room, the minimum safe restart time interval of the air conditioner, and the mode switching time interval is as follows:

[0009] Where T is the mode switching temperature offset, and K is the maximum allowable offset range of the preset temperature recovery range. The minimum safe restart interval for the air conditioner. This is the time interval for mode switching.

[0010] Optionally, determining the mode switching temperature threshold for the current operating mode based on the mode switching temperature offset specifically involves: If the current mode is air conditioning mode, then the difference between the lower limit of the preset warming range of the communication equipment room and the mode switching temperature offset is determined as the mode switching temperature threshold. If the current mode is fresh air mode, then the sum of the upper limit of the preset return temperature range of the communication equipment room and the mode switching temperature offset is determined as the mode switching temperature threshold.

[0011] Optionally, determining the difference between the lower limit of the preset warming range of the communication equipment room and the mode switching temperature offset as the mode switching temperature threshold further includes: Obtain the indoor temperature sampling curve within the aforementioned mode switching time interval; The average slope of the indoor temperature sampling curve is calculated to obtain the first rate of temperature change. If the first temperature change rate is greater than or equal to a preset first temperature change rate threshold, then a first correction factor is determined based on the first temperature change rate. The mode switching temperature offset is corrected using the first correction factor, and the difference between the preset lower limit of the recovery range of the communication equipment room and the correction result is used to determine the mode switching temperature threshold.

[0012] Optionally, determining the mode switching temperature threshold as the sum of the upper limit of the preset warming range of the communication equipment room and the mode switching temperature offset further includes: Obtain the indoor temperature sampling curve within the aforementioned mode switching time interval; The average slope of the indoor temperature sampling curve is calculated to obtain the second rate of temperature change. If the second temperature change rate is greater than or equal to a preset second temperature change rate threshold, then a second correction factor is determined based on the second temperature change rate. The second correction factor is used to correct the mode switching temperature offset, and the upper limit of the preset warming range of the communication equipment room is summed with the correction result to determine the mode switching temperature threshold.

[0013] Optionally, determining whether the operating mode switching conditions are met based on the current indoor temperature and the mode switching temperature threshold specifically involves: If the current operating mode is air conditioning mode, then determine whether the current indoor temperature is less than or equal to the mode switching temperature threshold. If yes, then the operating mode switching condition is met; otherwise, the operating mode switching condition is not met. If the current operating mode is fresh air mode, then determine whether the current indoor temperature is greater than or equal to the mode switching temperature threshold. If yes, then the operating mode switching conditions are met; otherwise, the operating mode switching conditions are not met.

[0014] Secondly, this application provides a fresh air cooling control system for a communication equipment room, used to execute a fresh air cooling control method for a communication equipment room as described in any one of the first aspects. The system is a fresh air cooling control system, comprising an acquisition module, a processing module, and an output module, wherein: The acquisition module is used to acquire the outdoor temperature, indoor temperature, operating mode, and the switching time of the nearest operating mode in the communication equipment room at the current moment. The operating mode is either the air conditioning mode or the fresh air mode. The processing module is used to calculate the mode switching time interval between the current time and the nearest operating mode switching time when the outdoor temperature is less than or equal to a preset temperature threshold. Calculate the mode switching temperature offset based on the mode switching time interval; Based on the mode switching temperature offset, determine the mode switching temperature threshold of the current operating mode; The output module is used to determine whether the operating mode switching conditions are met based on the current indoor temperature and the mode switching temperature threshold. If satisfied, output the operation mode switching instruction; If the conditions are not met, the current operating mode will be maintained.

[0015] Thirdly, this application provides an electronic device including a processor, a memory, a user interface, and a network interface. The memory is used to store instructions, the user interface and the network interface are used to communicate with other devices, and the processor is used to execute the instructions stored in the memory to cause the electronic device to perform the method as described in any one of the first aspects.

[0016] Fourthly, this application provides a computer-readable storage medium storing instructions that, when executed, perform the method described in any one of the first aspects.

[0017] In summary, one or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This method acquires the current outdoor temperature, indoor temperature, operating mode, and the switching time of neighboring operating modes in the communication equipment room. When the outdoor temperature is low, it uses the time interval between the current moment and the switching time of neighboring operating modes as input to calculate the mode switching temperature offset. This offset increases as the mode switching time interval shortens and decreases as it lengthens, thus quantifying the impact of short-interval start-stop cycles on the air conditioning system. Then, based on the current operating mode, the offset is converted into a mode switching temperature threshold with a different direction. Specifically, in air conditioning mode, the lower limit of the return temperature range is subtracted from the offset, lowering the switching threshold to fresh air mode. In fresh air mode, the return temperature range is lowered. The upper limit of the temperature range plus the offset raises the threshold for switching to air conditioning mode. When communication load fluctuations cause changes in indoor temperature, the system determines whether the switching conditions are met based on the relationship between the indoor temperature and the mode switching temperature threshold. When the mode switching interval is short, the lower limit is significantly lowered and the upper limit is significantly raised. Both of these factors together suppress repeated switching between modes, providing sufficient safe start-stop intervals for the air conditioner. When the mode switching interval is long, the offset naturally decays, the lower limit rises and the upper limit falls, restoring the system's timely response capability to outdoor natural cold sources. This achieves an adaptive balance between air conditioning heat dissipation and fresh air heat dissipation, thereby improving the energy-saving effect of the communication equipment room.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] This application provides a method for controlling the ventilation and heat dissipation of a communication equipment room. This method is applied to a ventilation and heat dissipation control system, such as... Figure 1 As shown, the method includes steps S101 to S107, which are as follows: S101. Obtain the current outdoor temperature, indoor temperature, operating mode, and the switching time of the nearest operating mode in the communication equipment room. The operating mode can be either air conditioning mode or fresh air mode.

[0024] In the above steps, the fresh air cooling control system collects the current indoor and outdoor temperatures in real time using indoor and outdoor temperature sensors already deployed in the communication equipment room. Simultaneously, it reads the current operating mode flag, which records whether the system is currently in air conditioning or fresh air mode. Furthermore, the system reads the time of the most recent mode switch from its internal mode switching log to obtain the timestamps of nearby operating mode switches.

[0025] S102. When the outdoor temperature is less than or equal to the preset temperature threshold, calculate the mode switching time interval between the current time and the nearest operating mode switching time.

[0026] S103. Calculate the mode switching temperature offset based on the mode switching time interval.

[0027] In steps S102 to S103 above, in order to ensure the effective cooling of the fresh air system, it is necessary to first determine whether the current outdoor temperature meets the conditions for enabling the fresh air mode. Specifically, the current outdoor temperature is compared with a preset temperature threshold. If the current outdoor temperature is less than or equal to the preset temperature threshold, it means that the outdoor air has the ability to cool the computer room. Otherwise, it means that the outdoor air does not have the ability to cool. At this time, the air conditioning mode is maintained, the subsequent steps are skipped, and the process returns to S101 to continue monitoring until the current outdoor temperature meets the conditions for enabling the fresh air mode. The preset temperature threshold is a temperature value set in the project according to the cooling requirements of the communication computer room.

[0028] When the outdoor temperature at the current moment meets the conditions for enabling the fresh air mode, considering that the air conditioner compressor starts and stops in a short period of time, and the high and low pressures of the refrigeration system are not yet balanced, a start-stop current and mechanical shock far exceeding those of normal operation will be generated, resulting in significant additional energy loss. The severity of this loss is closely related to the start-stop interval of the air conditioner compressor; specifically, the shorter the start-stop interval, the greater the additional energy loss. Therefore, this application calculates the mode switching interval between the current moment and the nearest operating mode switching moment, and then obtains the maximum allowable deviation of the preset temperature recovery range of the communication equipment room and the minimum safe restart interval of the air conditioner. The mode switching interval is converted into a mode switching temperature deviation that decays over time. This quantifies the damage risk borne by the air conditioner compressor under different start-stop intervals into a dynamic temperature deviation, thereby providing a reliable quantitative basis for the timing of subsequent operating mode switching, as detailed below:

[0029] Where T is the mode switching temperature offset, and K is the maximum allowable offset range of the preset temperature recovery range. The minimum safe restart interval for the air conditioner. This is the time interval for mode switching.

[0030] In the above formula, the maximum allowable deviation of the preset temperature recovery range refers to the maximum temporary breach of the temperature recovery range boundary allowed to protect the air conditioning compressor. Its value is determined comprehensively based on the communication equipment room's tolerance for short-term temperature exceedances and the severity of start-up and shutdown damage to the air conditioning compressor. The temperature recovery range is the target control range for the thermal environment management of the communication equipment room. For example, if the preset temperature recovery range is... Then K is 1 degree. When the mode switching time interval approaches 0, it indicates that the compressor faces the risk of starting and stopping again very soon after completing one start-stop cycle. As the temperature shift value approaches 1, the temperature offset T during mode switching approaches K, requiring the air conditioning compressor to operate over a wider temperature range to reduce the risk of loss. Furthermore, as the time interval between mode switching cycles continues to increase... As the temperature gradually decreases, the temperature offset during mode switching also decreases, allowing more time for the high and low pressures inside the air conditioner compressor to gradually reach equilibrium. This reduces the risk of damage during start-up and shutdown. At this point, switching can be performed according to the normal temperature switching threshold, achieving an adaptive balance between the protection strength of the air conditioner compressor and the utilization rate of the natural cold source.

[0031] In one possible implementation, because the electromechanical shock and mechanical wear experienced by the air conditioner compressor during startup are far greater than those during shutdown, switching from fresh air mode to air conditioning mode carries a higher risk of damage than switching from air conditioning mode to fresh air mode. Furthermore, when the communication load experiences irregular and violent oscillations within a short period, the two modes will undergo multiple irregular mode switches in a short time. The cumulative damage to the air conditioner compressor under these conditions is far greater than that from periodic switches with shorter intervals but uniform patterns. Therefore, when calculating the mode switching temperature offset, this application further needs to combine the mode switching direction with the historical switching disorder to differentiate the attenuation rate of the offset, thereby more closely reflecting the actual damage state of the equipment. Specifically: This application determines the first direction by switching from air conditioning mode to fresh air mode, and the second direction by switching from fresh air mode to air conditioning mode. Then, it obtains the mode switching direction at the moment of switching the nearest operating mode. If the nearest operating mode switches to the first direction, the air conditioning compressor has just stopped and has not yet experienced the startup impact, and is in a relatively safe state. Therefore, the minimum safe restart time interval of the air conditioner is directly used as the decay time constant to calculate the mode switching temperature offset.

[0032] If the nearest neighbor operating mode switches to the second direction, the compressor has just experienced a startup shock and is in a vulnerable state. In this case, this application further obtains a sequence of historical mode switching time intervals within a preset time period before the current moment. Then, it calculates the coefficient of variation of this historical mode switching time interval sequence and uses it as the oscillation coefficient. The larger the oscillation coefficient, the higher the cumulative damage to the air conditioning compressor, and the more time is required for recovery. Therefore, based on the oscillation coefficient, the decay time constant is corrected to obtain the equivalent decay time constant in the second direction. The correction method is as follows:

[0033] in, The equivalent decay time constant in the second direction, This is the decay time constant corresponding to the minimum safe restart interval of the air conditioner. This is the oscillation coefficient.

[0034] Then, the original decay time constant is replaced with the corrected equivalent decay time constant to calculate the mode switching temperature offset in the second direction, thereby slowing down the decay rate of the mode switching temperature offset and maintaining a longer hysteresis expansion state, thus providing the air conditioning compressor with more recovery time.

[0035] S104. Determine the mode switching temperature threshold of the current operating mode based on the mode switching temperature offset.

[0036] In the above steps, the current operating mode is first identified. Then, based on the different operating modes, algebraic operations with opposite directions are used to convert the mode switching temperature offset into a dynamic switching threshold bound to the current mode. Specifically: If the current operating mode is air conditioning mode, the difference between the lower limit of the preset return temperature range of the communication equipment room and the mode switching temperature offset is determined as the mode switching temperature threshold when switching to fresh air mode; if the current operating mode is fresh air mode, the sum of the upper limit of the preset return temperature range of the communication equipment room and the mode switching temperature offset is determined as the mode switching temperature threshold when switching to air conditioning mode. In this way, the start and stop timing of the adaptive and flexible air conditioning mode is minimized, so as to reduce the impact on the air conditioner during each start and stop process and reduce additional energy loss.

[0037] In one possible implementation, when the communication equipment room is operating in air conditioning mode, if the communication load drops sharply, the heat load of the equipment room decreases drastically, and the indoor temperature will drop rapidly. At this time, because the lower limit for dynamically switching to fresh air mode is lowered, the system will continuously judge that the room temperature has not yet reached the switching threshold and delay the switch from air conditioning mode to fresh air mode, resulting in the indoor temperature being far below the lower limit of the recovery range. This not only causes unnecessary waste of cooling capacity but may even cause the temperature to drop below the minimum allowable operating temperature of the communication equipment, threatening the safe operation of the equipment. Therefore, when determining the mode switching temperature threshold in air conditioning mode, this application further combines the trend of indoor temperature changes to perform a safety clamp on the effective range of the offset. Specifically: First, the indoor temperature sampling curve within the mode switching time interval is obtained. Then, the slope curve of the indoor temperature sampling curve is calculated, and the mean of the slope curve is calculated to obtain the first temperature change rate. If the first temperature change rate is greater than or equal to the preset first temperature change rate threshold, it indicates that the current indoor temperature is rapidly decreasing. Therefore, the ratio of the preset first temperature change rate threshold to the first temperature change rate is determined as the first correction factor. Then, the mode switching temperature offset is multiplied by the first correction factor, and the product result is subtracted from the upper limit of the preset warming range of the communication equipment room to obtain the mode switching temperature threshold when the room temperature is rapidly decreasing. This raises the lower limit of dynamic switching to fresh air mode, thereby switching to fresh air mode in a timely manner to curb the risk of overcooling.

[0038] In one possible implementation, when the communication equipment room is operating in fresh air mode, if the communication load increases sharply, the heat load of the equipment room will increase rapidly, and the indoor temperature will rise quickly. The outdoor fresh air may not be able to suppress the indoor temperature rise due to its limited cooling capacity. At this time, because the upper limit for dynamically switching to air conditioning mode is raised, the system will continuously judge that the room temperature has not yet reached the switching threshold and will delay switching from fresh air mode to air conditioning mode, resulting in the indoor temperature being far higher than the upper limit of the recovery range, causing the equipment to degrade in performance due to overheating. Therefore, this application, when determining the mode switching temperature threshold in fresh air mode, further combines the trend of indoor temperature changes and also performs a safety clamp on the effective range of the offset. Specifically: First, the indoor temperature sampling curve within the mode switching time interval is obtained. Then, the average slope of the indoor temperature sampling curve is calculated to obtain the second temperature change rate. If the second temperature change rate is greater than or equal to the preset second temperature change rate threshold, it indicates that the current indoor temperature is rising rapidly. Therefore, the ratio of the preset second temperature change rate threshold to the second temperature change rate is determined as the second correction factor. Then, the mode switching temperature offset is multiplied by the second correction factor, and the upper limit of the preset warming range of the communication room is added to the product to obtain the mode switching temperature threshold when the room temperature rises rapidly. This reduces the upper limit of dynamic switching to air conditioning mode, thereby switching to air conditioning mode in a timely manner to curb the risk of overheating.

[0039] S105. Based on the current indoor temperature and the mode switching temperature threshold, determine whether the operating mode switching conditions are met.

[0040] S106. If satisfied, output the running mode switching instruction.

[0041] S107. If not satisfied, maintain the current operating mode.

[0042] In steps S105 to S107 above, when the current operating mode is air conditioning mode, it is determined whether the current indoor temperature is less than or equal to the mode switching temperature threshold. If the indoor temperature is less than or equal to the dynamic lower limit, it means that the heat load inside the computer room has been sufficiently reduced and is suitable for fresh air cooling. At this time, it is determined that the operating mode switching condition is met, and a switching command from air conditioning mode to fresh air mode is output. The actuator is controlled to turn off the air conditioning compressor and open the fresh air valve to introduce outdoor cold air to cool the computer room. If the indoor temperature is greater than the dynamic lower limit, it means that the heat load inside the computer room is still high, and the outdoor fresh air may not be able to effectively suppress the residual heat inside the computer room, causing the room temperature to rise rapidly after the switch. Therefore, it is determined that the operating mode switching condition is not met, and the air conditioning mode continues to operate.

[0043] When the current operating mode is air conditioning mode, it is determined whether the current indoor temperature is greater than or equal to the mode switching temperature threshold. If the indoor temperature is greater than or equal to the dynamic upper limit, it means that the outdoor fresh air can no longer suppress the heat load of the computer room. At this time, it is determined that the operating mode switching condition is met, and a switching command is output to switch from fresh air mode to air conditioning mode. The actuator is controlled to close the fresh air valve and start the air conditioning compressor, so that the air conditioning provides cooling for the computer room. If the indoor temperature is less than the dynamic upper limit, it means that the current room temperature is still within the range that the fresh air can control. It is determined that the operating mode switching condition is not met, and the fresh air mode continues to operate to save energy.
