Description

Technical Field

[0001] The present invention relates to the field of computer room equipment control, and more particularly to a computer room load power adaptive control method, system and electronic equipment. Background Art

[0002] In recent years, with the rapid development of new-generation information technology, data rooms integrated with various servers and ancillary equipment have become important infrastructure and are the carriers of various applications such as big data, artificial intelligence, AR / VR, industrial Internet of Things, smart cities, smart energy, smart finance, 5G, etc. Their scale has experienced explosive growth.

[0003] At present, the temperature control system of the computer room mainly adopts the pure temperature method for temperature control. Due to the temperature lag effect, for occasions with higher requirements, the PID method is mostly used for real-time adjustment. However, due to the special environment of the data room, the control method of using PID real-time adjustment can no longer meet the increasingly stringent energy-saving index requirements of the telecommunications industry. Environmental regulation of the computer room requires not only controlling the temperature, but also controlling the humidity of the computer room. In addition, it is necessary to combine outdoor temperature and humidity information to improve the energy utilization rate of environmental conditioning equipment such as fans and air conditioners. Summary of the Invention

[0004] The present invention aims to solve the problem that the PID real-time control method adopted in the existing computer room can no longer effectively meet the energy-saving requirements of the computer room environmental control equipment. Therefore, the present invention provides a computer room load power adaptive control method, system and electronic equipment. The present invention calculates the cooling and humidification capacity of the wet curtain fan when the computer room reaches the preset temperature and humidity threshold through the total power generated by the servers in the computer room and the heat taken away by the wet curtain fan, and then collects data in the computer room at equal time intervals, and obtains the data slope of temperature and humidity based on this data. The current cooling and humidification capacity of the current wet curtain fan is analyzed according to the changing trend of the data slope, and the current cooling and humidification capacity is compared with the cooling and humidification capacity when the preset temperature and humidity threshold is reached, so as to regulate the operating parameters of the wet curtain fan. The present invention combines the temperature and humidity uniformity analysis and the prediction of the temperature and humidity trend to adaptively control the operating state of the wet curtain fan, thereby effectively reducing the energy consumption of the wet curtain fan, thereby improving the energy utilization rate of the wet curtain fan.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides a method for adaptively controlling load power in a computer room, the method comprising:

[0007] Collect the temperature and humidity parameters of the air inlet and outlet of the wet curtain fan, as well as the total power generated by the equipment in the computer room during the same time period;

[0008] Calculate the heat removed by the wet curtain fan according to the air inlet temperature and humidity parameters and the air outlet temperature and humidity parameters;

[0009] The cooling and humidification capacity of the wet curtain fan when the room reaches a preset temperature and humidity threshold is calculated based on the total power and the heat, and the wind speed and humidification intensity of the wet curtain fan are set according to the cooling capacity;

[0011] Analyze the current cooling and humidification capabilities of the wet curtain fan current control parameters based on the trend of the data slope;

[0012] If the current cooling and humidification capacity is lower than the cooling and humidification capacity, the wind speed and humidification intensity of the wet curtain fan are adjusted to control the cooling and humidification capacity; otherwise, the parameters of the wet curtain fan are collected again in the next equal time period to control the cooling and humidification capacity.

[0013] In one possible implementation, if the current cooling and humidification capacity is lower than the cooling and humidification capacity, adjusting the wind speed and humidification intensity of the wet curtain fan to control the cooling and humidification capacity includes:

If the rising slope of the temperature and humidity data is greater than the preset temperature and humidity slope threshold, the evenly divided ratio value is added to the current margin ratio, and the wind speed and humidification intensity of the wet curtain fan are adjusted until the rising slope of the temperature and humidity data is no greater than the preset temperature and humidity slope threshold.

[0017] If the load parameter of the wet curtain fan reaches the maximum load power and the temperature in the computer room does not meet the temperature threshold, the air conditioner is started for cooling and the wet curtain fan is turned off; or if the humidity data in the computer room is greater than the maximum humidity threshold, the air conditioner is started for dehumidification and the wet curtain fan is turned off.

[0018] In one possible implementation, the current real-time temperature and humidity of the computer room after cooling and dehumidification by air conditioning are collected, and it is determined whether the real-time temperature and humidity meet the start-up conditions of the wet curtain fan. If so, the air conditioner is turned off and the wet curtain fan is started to adjust the temperature and humidity of the computer room. If not, the air conditioner is continued to be started for cooling or dehumidification.

[0019] In a possible implementation, if the real-time temperature of the real-time temperature and humidity is 20-25 degrees and the real-time humidity is lower than 55%, the air conditioner is turned off and the wet curtain fan is started.

[0020] In a possible implementation, the temperature threshold is 20-25 degrees, and the maximum humidity threshold is 85%.

[0021] In one possible implementation, it also includes:

[0022] Real-time collection of indoor and outdoor temperature parameters inside and outside the computer room;

[0023] When the indoor temperature parameter is greater than the outdoor temperature parameter, the indoor temperature of the room is reduced by 7 degrees when the wet curtain fan reaches the maximum wind speed, and the temperature value in the room when the wet curtain fan reaches the maximum wind speed is obtained;

[0025] determining an outdoor temperature threshold value based on the sum of the temperature value and the temperature difference;

[0026] If the outdoor temperature parameter is not greater than the outdoor temperature threshold, the wet curtain fan is started.

[0027] In a possible implementation, if the outdoor temperature parameter is not greater than the outdoor temperature threshold, the wet curtain fan is started, further comprising:

[0028] The real-time humidity parameter in the computer room is collected in real time to determine whether the real-time humidity parameter is lower than 55%. If it is lower and the outdoor temperature parameter is not greater than the outdoor temperature threshold, the wet curtain fan is started. Otherwise, the air conditioner is started for dehumidification first, and the air conditioner is turned off after the real-time humidity parameter is lower than 55%.

[0029] In a second aspect, the present invention provides a computer room load power adaptive control system, comprising:

[0030] The data acquisition module is used to collect the temperature and humidity parameters of the air inlet and outlet of the wet curtain fan and the total power generated by the equipment in the computer room within the same time period;

[0031] A heat calculation module, used to calculate the heat taken away by the wet curtain fan according to the temperature and humidity parameters of the air inlet and the temperature and humidity parameters of the air outlet;

[0032] A wet curtain fan parameter setting module is used to calculate the cooling and humidifying capacity of the wet curtain fan when the room reaches a preset temperature and humidity threshold based on the total power and the heat, and to set the wind speed and humidification intensity of the wet curtain fan according to the cooling and humidifying capacity;

[0033] The temperature and humidity slope calculation module is used to obtain the data slope of the temperature and humidity in the computer room based on the data collected by the temperature and humidity sensors in the computer room during the same time period;

[0035] The wet curtain fan parameter control module is used to adjust the wind speed and humidification intensity of the wet curtain fan to control the cooling and humidification capacity if the current cooling and humidification capacity is lower than the cooling and humidification capacity; otherwise, it waits for the next equal time period to collect the parameters of the wet curtain fan again to control the cooling and humidification capacity.

[0036] In a third aspect, the present invention provides an electronic device, comprising a memory and a processor;

[0037] At least one instruction is stored in the memory, and the at least one instruction is loaded and executed by the processor to implement the control method as described in the first aspect.

[0038] Combined with the above technical solutions, compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The present invention calculates the cooling and humidifying capacity of the wet curtain fan when the computer room reaches the preset temperature and humidity threshold value through the total power generated by the servers in the computer room and the heat taken away by the wet curtain fan, and then collects data in the computer room at equal time intervals. The data slope of temperature and humidity is obtained based on this data, and the current cooling and humidifying capacity of the current wet curtain fan is analyzed according to the changing trend of the data slope. The current cooling and humidifying capacity is compared with the cooling and humidifying capacity when the preset temperature and humidity threshold value is reached, so as to regulate the operating parameters of the wet curtain fan. The present invention combines the temperature and humidity uniformity analysis with the prediction of the temperature and humidity trend, and adaptively controls the operating state of the wet curtain fan, thereby effectively reducing the energy consumption of the wet curtain fan, thereby improving the energy utilization rate of the fan.

[0040] 2. When the present invention detects that the indoor temperature or humidity reaches a certain threshold, the air conditioner will be directly started to cool or dehumidify due to insufficient cooling capacity of the wet curtain fan or excessive indoor humidity, so as to avoid damage to data equipment due to low cooling or dehumidification efficiency.

[0041] 3. When the present invention detects that the outdoor temperature has dropped to a certain level, it calculates the indoor temperature according to the maximum cooling capacity of the wet curtain fan. Then, it combines the real-time power of the machine room and the heat that the wet curtain fan can take away at its maximum cooling capacity to determine whether to force the wet curtain fan to start, thereby further saving energy consumption.

[0047] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example 1

[0049] like Figure 1 As shown, the first embodiment of the present application provides a method for adaptively controlling a computer room load power, which is mainly used to control the output power of an environmental conditioning device in a data center computer room, thereby reducing the energy consumption of the computer room environmental conditioning device, including:

[0050] Step 110, collecting the air inlet temperature and humidity parameters, air outlet temperature and humidity parameters of the wet curtain fan and the total power generated by the equipment in the computer room during the equal time period;

[0051] In this embodiment, at least one set of temperature and humidity sensors is set at the air inlet and the air outlet, respectively used to detect the air inlet temperature and humidity parameters and the air outlet temperature and humidity parameters. If there is only one set of temperature and humidity sensors, the air inlet temperature and humidity and the air outlet temperature and humidity measured by the set of temperature sensors at the current moment can be used as the temperature and humidity data of the air inlet temperature and humidity and the air outlet temperature and humidity. In order to improve the measurement accuracy and avoid temperature and humidity fluctuations or measurement errors, the average value of the air inlet temperature and humidity and the average value of the air outlet temperature and humidity measured by the set of temperature sensors over a period of time can be used as the temperature and humidity data of the air inlet temperature and humidity and the air outlet temperature and humidity. If there are M sets of temperature sensors, M ≥ 2, then M sets of air inlet temperature and outlet temperature can be collected at the same time, and the average value or the maximum value of the multiple sets of air inlet temperature and humidity can be used as the temperature and humidity data of the air inlet temperature and humidity, and the average value or the maximum value of the multiple sets of air outlet temperature and humidity can be used as the temperature and humidity data of the air outlet temperature and humidity.

[0052] The total power generated by the equipment in the computer room, such as computers, servers, gateways, etc., can be obtained by reading the voltage and current at the power switch of the equipment.

[0053] Step 120, calculating the heat removed by the wet curtain fan according to the air inlet temperature and humidity parameters and the air outlet temperature and humidity parameters;

[0054] In this embodiment, the heat carried by the wet curtain fan is calculated based on the inlet and outlet temperature and humidity parameters of the computer room collected in step 110. According to the basic physical formula: Q = c*m*Δt, Q is the heat removal capacity, where c is the specific heat capacity of the object, m is the ventilation volume per unit time (related to the wind speed of the wet curtain fan), and Δt is the temperature difference between the air inlet and the air outlet. According to this formula, to increase Q, it is necessary to increase c, m, and Δt. This is the principle of an evaporative wet curtain fan. As for humidity, humidity is expressed as the amount of water in the air. Therefore, by controlling the amount of water added to the evaporative wet curtain fan through program control, c can be increased (adding water (which has a large specific heat capacity, air: 1030 J / (kg·°C), water: 4200 J / (kg·°C)) to increase the specific heat capacity. Increasing m also increases the ventilation volume per unit time. Since the evaporation of water removes heat, the air inlet temperature decreases, thereby increasing Δt.

[0055] Step 130, calculating the cooling and humidifying capacity of the wet curtain fan when the room reaches a preset temperature and humidity threshold based on the total power and the heat, and setting the wind speed and humidification intensity of the wet curtain fan according to the cooling capacity;

[0056] In this embodiment, it should be noted that the cooling and humidifying capacity refers to the cooling effect and humidity effect that can be achieved by the wet curtain fan at a certain speed and a certain water addition amount.

[0057] At a certain time interval, the total power of the computer room multiplied by the time will generate corresponding heat, and the amount of heat that the wet curtain fan can take away under the corresponding operating parameters is quantitative. Therefore, according to the real-time heat generated by the real-time power of the computer room equipment and the heat that the wet curtain fan can take away under certain operating parameters, the cooling and humidification capacity of the wet curtain fan is calculated when the computer room reaches the preset temperature and humidity threshold, and the wind speed and humidification intensity of the wet curtain fan are set according to the cooling capacity. In layman's terms, it is necessary to adjust the speed and water addition amount of the wet curtain fan to a certain value to control the indoor environmental parameters of the computer room under appropriate conditions.

[0058] Step 140, obtaining the data slope of the temperature and humidity in the computer room based on the data collected by the temperature and humidity sensors in the computer room during the same time period;

[0059] In this embodiment, the equal time period is generally set to 1 minute, or it can be 2 minutes, which has little impact on the environmental allocation of the computer room. When calculating the data slope of the temperature and humidity data, it is necessary to convert minutes into seconds, and it is also necessary to discard some data with obvious deviations to ensure the accuracy of the data slope.

[0060] Step 150, analyzing the current cooling and humidification capabilities of the wet curtain fan current control parameters according to the trend of the data slope;

[0061] In this embodiment, the current cooling and humidification capacity of the wet curtain fan control parameters is analyzed based on the rising or falling trend of the temperature and humidity data calculated in step 140 to determine whether they meet the preset temperature and humidity thresholds. For example, when the rising slope of the temperature data changes significantly, it indicates that the current temperature has changed significantly compared to the previous period, and the wet curtain fan speed needs to be increased to reduce the indoor temperature. For another example, when the rising slope of the humidity data changes significantly, it indicates that the current indoor humidity has changed significantly compared to the previous period, and the amount of water added to the wet curtain fan needs to be reduced to reduce the moisture in the air. If the maximum value of the specified humidity range is exceeded but the condition requiring dehumidification through air conditioning is not reached, the water addition to the wet curtain fan can be stopped, and the indoor heat can be allowed to dissolve the moisture in the air. This achieves real-time adjustment to ensure that the computer room is within an appropriate temperature and humidity range. It should be noted that when the data slope changes smoothly or when it is declining, the operating parameters of the wet curtain fan are adjusted using the same control principle.

[0062] Step 160: If the current cooling and humidification capacity is lower than the cooling and humidification capacity, adjust the wind speed and humidification intensity of the wet curtain fan to control the cooling and humidification capacity; otherwise, wait for the next equal time period to collect the parameters of the wet curtain fan again to control the cooling and humidification capacity.

[0063] In this embodiment, if the current cooling and humidification capacity is lower than the cooling and humidification capacity, it means that the operating parameters of the wet curtain fan at the current moment cannot meet the environmental control in the computer room, and it is necessary to readjust the wind speed and humidification intensity of the wet curtain fan to increase the cooling and humidification capacity of the wet curtain fan. If the current cooling and humidification capacity is greater than or equal to the cooling and humidification capacity, it means that the current operating parameters are appropriate, and it is necessary to wait for the next time period to wait for the inlet and outlet temperature and humidity parameters of the wet curtain fan, the outlet temperature and humidity parameters, and the total power generated by the equipment in the computer room. Because the total power of the computer room may change, the cooling and humidification capacity of the wet curtain fan will also need to be adjusted accordingly. Then, according to the subsequent steps, the cooling and humidification capacity can be adjusted, thereby realizing adaptive control of the load power of the computer room environmental control equipment and achieving energy saving to the greatest extent.

[0064] It should be understood that, in terms of current requirements for data center rooms, an indoor temperature of 20-25 degrees and an indoor humidity of 40-55% are considered to be a relatively suitable indoor environment.

[0065] In summary, the adaptive control method of the present invention calculates the cooling and humidifying capacity of the wet curtain fan when the computer room reaches the preset temperature and humidity threshold value through the total power generated by the servers in the computer room and the heat taken away by the wet curtain fan, and then collects data in the computer room at equal time intervals, and obtains the data slope of temperature and humidity based on this data. The current cooling and humidifying capacity of the current wet curtain fan is analyzed according to the changing trend of the data slope, and the current cooling and humidifying capacity is compared with the cooling and humidifying capacity when the preset temperature and humidity threshold value is reached, so as to regulate the operating parameters of the wet curtain fan. The present invention combines the temperature and humidity uniformity analysis with the prediction of the temperature and humidity trend, and adaptively controls the operating state of the wet curtain fan, thereby effectively reducing the energy consumption of the wet curtain fan, thereby improving the energy utilization rate of the wet curtain fan.

[0066] In one possible implementation, if the current cooling capacity is lower than the cooling capacity, the wind speed and humidification intensity of the wet curtain fan are adjusted to control the cooling capacity; otherwise, the next adjustment cycle is waited for, including:

[0067] The margin ratio of the total power and the heat is evenly divided. If the rising slope of the temperature and humidity data is greater than the preset temperature and humidity slope threshold, the evenly divided ratio value is added to the current margin ratio, and the wind speed and humidification intensity of the wet curtain fan are adjusted until the rising slope of the temperature and humidity data is no greater than the preset temperature and humidity slope threshold.

[0068] Specifically, the real-time total power of the computer room is collected. In theory, the heat is the same as the total power of the computer room, but in reality there is a certain margin ratio: currently 10%-100%, broken down by 10%. If the temperature rise slope is too large, the margin ratio will be increased, and the computer room will achieve a dynamic temperature balance. The coordination controller mainly controls the cooling capacity by adjusting the water speed (water added to the wet curtain) and the wind speed of the fresh air on the wet curtain.

[0069] Example 2

[0070] like Figure 2 As shown, in the second embodiment of the present application, based on the first embodiment, the adaptive control method further includes:

[0071] Obtain the load parameters of the wet curtain fan and the temperature and humidity data in the machine room;

[0072] If the load parameter of the wet curtain fan reaches the maximum load power and the temperature in the computer room does not meet the temperature threshold, the air conditioner is started for cooling and the wet curtain fan is turned off; or if the humidity data in the computer room is greater than the maximum humidity threshold, the air conditioner is started for dehumidification and the wet curtain fan is turned off.

[0073] Specifically, it should be noted that under the same time, the energy consumption of air conditioning is higher than that of wet curtain fan. Therefore, in terms of temperature and humidity regulation, wet curtain fan control is the main control, and air conditioning control is auxiliary.

[0074] In this embodiment, in one implementation, when the temperature continues to rise and the wet curtain fan can no longer effectively control the temperature, it is necessary to start the air conditioner to adjust the environmental parameters of the computer room; therefore, it is considered that when the speed of the wet curtain fan is at the maximum speed, the temperature in the computer room still does not meet the set temperature threshold, and the air conditioner needs to be started to cool down. In another implementation, when the indoor humidity reaches the maximum humidity threshold, dehumidification is required immediately, because the higher the humidity, the more water content in the air. When the data equipment in the computer room is running, if the water content of the surrounding air is high, it will cause the equipment to absorb water in the air, thereby causing rust on components such as the internal circuit board of the equipment, reducing the service life of the data equipment. Therefore, it is necessary to start the air conditioner for dehumidification.

[0075] In one possible implementation, the current real-time temperature and humidity of the computer room after cooling and dehumidification by air conditioning are collected, and it is determined whether the real-time temperature and humidity meet the start-up conditions of the wet curtain fan. If so, the air conditioner is turned off and the wet curtain fan is started to adjust the temperature and humidity of the computer room. If not, the air conditioner is continued to be started for cooling or dehumidification.

[0076] Specifically, in this embodiment, for Figure 2 After cooling or dehumidifying, the adaptive control method shown in the figure collects the current real-time temperature and humidity of the computer room after cooling and dehumidifying by air conditioning, and determines whether the real-time temperature and humidity meet the start-up conditions of the wet curtain fan. The start-up condition here is that after cooling or dehumidifying by air conditioning, the temperature has reached the appropriate temperature and humidity value for the computer room, then the wet curtain fan is started to avoid increased energy consumption in the computer room due to long-term air conditioning regulation.

[0077] In a possible implementation, if the real-time temperature of the real-time temperature and humidity is 20-25 degrees and the real-time humidity is lower than 55%, the air conditioner is turned off and the wet curtain fan is started.

[0078] Specifically, the suitable temperature value of the above-mentioned computer room is 20-25 degrees, and the humidity is lower than 55%.

[0079] In a possible implementation, the temperature threshold is 20-25 degrees, and the maximum humidity threshold is 85%.

[0080] Specifically, this embodiment specifically defines the maximum humidity threshold value. As long as the humidity sensor detects that the humidity in the computer room is higher than 85%, the air conditioner is immediately started to perform dehumidification.

[0081] Example 3

[0082] like Figure 3 As shown, in the third embodiment of the present application, based on the first embodiment, the adaptive control method further includes:

[0083] Real-time collection of indoor and outdoor temperature parameters inside and outside the computer room;

[0084] When the indoor temperature parameter is greater than the outdoor temperature parameter, the indoor temperature of the room is reduced by 7 degrees when the wet curtain fan reaches the maximum wind speed, and the temperature value in the room when the wet curtain fan reaches the maximum wind speed is obtained;

[0085] Calculate the temperature difference between the air inlet and outlet based on the current real-time power of the equipment in the computer room;

[0086] determining an outdoor temperature threshold value based on the sum of the temperature value and the temperature difference;

[0087] If the outdoor temperature parameter is not greater than the outdoor temperature threshold, the wet curtain fan is started.

[0088] Specifically, when the outdoor temperature drops to a certain level, such as 20°C, the temperature of the wet curtain fan will drop directly to 13°C. Then, based on the real-time power of the computer room and the expected heat that can be taken away, it is determined whether to force the fan to start to further save energy. It should be understood that this embodiment three makes a judgment based on the current real-time power of the computer room equipment. If the real-time power of the computer room is large, it means that the heat generated by the data equipment in the computer room is high. Then, when the outdoor temperature is introduced, the outdoor temperature will be required to be lower. Therefore, in this embodiment, when it is determined that the indoor temperature parameter is lower than the outdoor temperature parameter, the indoor temperature will be reduced by 7 degrees when the wet curtain fan reaches the maximum speed. It should be noted that the temperature value that can be reduced by the wet curtain fan when it reaches the corresponding speed can be found in the lookup table of the wet curtain fan. The real-time heat is calculated based on the current real-time power of the equipment in the computer room, and the temperature difference between the air inlet and the air outlet is calculated based on the real-time heat (for details, please refer to Q=c*m*Δt in the above embodiment). The sum of the temperature value and the temperature difference is defined as the outdoor temperature threshold. If the outdoor temperature parameter is less than or equal to the outdoor temperature threshold, the wet curtain fan is started. Under the indoor and outdoor temperature conditions at this time, the energy consumption of the wet curtain fan can be effectively reduced by adopting the method of outdoor participation in indoor control.

[0089] In a possible implementation, if the outdoor temperature parameter is not greater than the outdoor temperature threshold, the wet curtain fan is started, further comprising:

[0090] The real-time humidity parameter in the computer room is collected in real time to determine whether the real-time humidity parameter is lower than 55%. If it is lower and the outdoor temperature parameter is not greater than the outdoor temperature threshold, the wet curtain fan is started. Otherwise, the air conditioner is started for dehumidification first, and the air conditioner is turned off after the real-time humidity parameter is lower than 55%.

[0091] Specifically, in this embodiment, in addition to the above-mentioned combination of outdoor temperature to determine whether to start the wet curtain fan for temperature adjustment, the current indoor humidity parameters also need to be considered. Therefore, the real-time humidity parameters in the computer room are collected in real time to determine whether the real-time humidity parameters are lower than 55% of the preset humidity threshold of 40%-55%. If not, the air conditioner is turned on for dehumidification until the humidity reaches below 55%, then the air conditioner is turned off and the wet curtain fan is turned on for adjustment, so as to provide energy utilization to the greatest extent, and also solve the defect of poor temperature and humidity control accuracy in the computer room.

[0093] like Figure 4 As shown, the fourth embodiment of the present application provides a computer room load power adaptive control system based on the first embodiment, including:

[0094] The data acquisition module is used to collect the temperature and humidity parameters of the air inlet and outlet of the wet curtain fan and the total power generated by the equipment in the computer room within the same time period;

[0095] A heat calculation module, used to calculate the heat taken away by the wet curtain fan according to the temperature and humidity parameters of the air inlet and the temperature and humidity parameters of the air outlet;

[0096] A wet curtain fan parameter setting module is used to calculate the cooling and humidifying capacity of the wet curtain fan when the room reaches a preset temperature and humidity threshold based on the total power and the heat, and to set the wind speed and humidification intensity of the wet curtain fan according to the cooling and humidifying capacity;

[0097] The temperature and humidity slope calculation module is used to obtain the data slope of the temperature and humidity in the computer room based on the data collected by the temperature and humidity sensors in the computer room during the same time period;

[0099] The wet curtain fan parameter control module is used to adjust the wind speed and humidification intensity of the wet curtain fan to control the cooling and humidification capacity if the current cooling and humidification capacity is lower than the cooling and humidification capacity; otherwise, it waits for the next equal time period to collect the parameters of the wet curtain fan again to control the cooling and humidification capacity.

[0100] The adaptive control system of the fourth embodiment of the present application calculates the cooling and humidifying capacity of the wet curtain fan when the computer room reaches the preset temperature and humidity threshold value through the total power generated by the servers in the computer room and the heat taken away by the wet curtain fan, and then collects data in the computer room at equal time intervals, and obtains the data slope of temperature and humidity based on this data. The current cooling and humidifying capacity of the current wet curtain fan is analyzed according to the changing trend of the data slope, and the current cooling and humidifying capacity is compared with the cooling and humidifying capacity when the preset temperature and humidity threshold value is reached, so as to regulate the operating parameters of the wet curtain fan. The present invention combines the temperature and humidity uniformity analysis with the prediction of the temperature and humidity trend, and adaptively controls the operating state of the wet curtain fan, thereby effectively reducing the energy consumption of the wet curtain fan, thereby improving the energy utilization rate of the wet curtain fan.
