Description

Technical Field

[0001] The embodiments of the present application relate to the field of intelligent control, and in particular to a temperature adjustment device, method, and computing equipment. Background Art

[0002] With the development of technology, the number of data centers is increasing and their distribution is becoming more and more widespread. The servers installed in the data center generate a lot of heat during operation, and the air conditioning system needs to input cold air to meet the heat dissipation requirements of the servers.

[0003] In the related art, the cold air outputted by the air-conditioning system as a whole is distributed relatively evenly to each cold channel, that is, the amount of cold air entering each cold channel is substantially the same.

[0004] However, the servers in the data center are not evenly distributed, and the heat generated by different servers is also different. For example, the far-end load is larger and the near-end load is smaller. If the cold air is distributed more evenly to each cold channel, some servers will not meet the heat dissipation requirements. Summary of the Invention

[0005] The embodiments of the present application provide a temperature adjustment device, method, and computing equipment for more reasonably distributing cold air to each cold channel, thereby reducing the occurrence of situations where servers cannot meet heat dissipation requirements.

[0006] In a first aspect, an embodiment of the present application provides a temperature adjustment device, the device comprising:

[0007] an adjustment coefficient determination module, configured to determine, for any cold aisle of a data center, a first adjustment coefficient corresponding to the cold aisle based on target measurement information of the cold aisle, an average of target measurement information of all cold aisles of the data center, and target setting information of an air-conditioning unit of the data center; wherein the target measurement information of the cold aisle includes a measured temperature inside the cold aisle, and the target setting information includes a set temperature of the air-conditioning unit; or, the target measurement information of the cold aisle includes a measured temperature and humidity inside the cold aisle, and the target setting information includes a set temperature and a set humidity of the air-conditioning unit;

[0008] an air pressure determination module, configured to determine a target air pressure corresponding to the inlet of the cold aisle according to a first adjustment coefficient corresponding to the cold aisle and a preset air pressure;

[0009] An air pressure comparison module, configured to compare the measured air pressure at the entrance of the cold aisle with the corresponding target air pressure;

[0010] The air valve control module is used to adjust the opening of the air valve at the entrance of the cold channel based on the comparison result; wherein, the entrance of the cold channel is used to input the cold air provided by the air-conditioning unit into the interior of the cold channel, and the air valve at the entrance is used to adjust the amount of cold air input into the interior of the cold channel.

[0011] In the above scheme, since the temperature and humidity inside different cold channels of the data center are different, the required amount of cooling air is different. Based on the temperature and humidity inside the cold channel, the temperature and humidity inside all cold channels of the data center, and the target setting information of the air-conditioning unit, the first adjustment coefficient of the cold channel is determined; then, the preset wind pressure of the cold channel is adjusted based on the first adjustment coefficient to obtain the target wind pressure at the entrance of the cold channel; according to the above target wind pressure (the target wind pressure represents the demand for cooling air in the cold channel) and the measured wind pressure (the measured wind pressure represents the input of cooling air in the cold channel), the valve opening at the entrance of the cold channel is adjusted, so that based on the different demand for cooling air in each cold channel, the amount of cooling air input to each cold channel is adjusted in a targeted manner, and the cooling air is more reasonably distributed to each cold channel of the data center, reducing the occurrence of servers failing to meet the heat dissipation requirements.

[0012] In some optional implementations, the air valve control module is specifically configured to:

[0013] If the measured wind pressure is less than the corresponding target wind pressure, increasing the air valve opening to increase the amount of cold air input into the cold aisle;

[0014] If the measured wind pressure is greater than the corresponding target wind pressure, the air valve opening is reduced to reduce the amount of cold air input into the cold channel.

[0015] In the above scheme, since the target wind pressure represents the demand for cold air in the cold channel, and the measured wind pressure represents the input of cold air in the cold channel, if the measured wind pressure is less than the corresponding target wind pressure, it means that the amount of cold air input into the cold channel cannot meet the demand of the cold channel. By increasing the opening of the air valve, the amount of cold air input into the cold channel is increased, and the situation where the servers corresponding to these cold channels cannot meet the heat dissipation requirements is reduced; if the measured wind pressure is greater than the corresponding target wind pressure, it means that the amount of cold air input into the cold channel exceeds the demand of the cold channel. By reducing the opening of the air valve, the amount of cold air input into the cold channel is reduced, and unnecessary cooling power consumption of the servers corresponding to these cold channels is reduced, so that the air conditioner can operate efficiently.

[0016] In some optional implementations, if the target measurement information of the cold aisle includes the measured temperature inside the cold aisle, and the target setting information includes the set temperature of the air-conditioning unit, the adjustment coefficient determination module is specifically configured to:

[0017] Determining a first difference between the temperature inside the cold aisle and the set temperature, and a second difference between an average of the temperatures inside all cold aisles and the set temperature;

[0018] A ratio of the first difference value corresponding to the cold channel to the second difference value is determined as a first adjustment coefficient corresponding to the cold channel.

[0019] In the above scheme, the greater the first difference between the measured temperature inside the cold channel and the above set temperature, the greater the amount of cold air required by the cold channel, and the greater the second difference between the average value of the measured temperature inside all cold channels and the above set temperature, the greater the amount of cold air required by all cold channels as a whole; therefore, by determining the above first difference and the second difference, and then determining the ratio of the first difference to the above second difference, the ratio accurately represents how to adjust the preset wind pressure of the corresponding cold channel based on the temperature.

[0020] In some optional implementations, if the target measurement information of the cold channel includes the measured temperature and humidity inside the cold channel, and the target setting information includes the set temperature and set humidity of the air-conditioning unit, the adjustment coefficient determination module is specifically configured to:

[0021] Selecting a larger ratio from a ratio of a first difference to a second difference corresponding to the cold channel and a ratio of a third difference to a fourth difference corresponding to the cold channel as a first adjustment coefficient corresponding to the cold channel;

[0022] Among them, the first difference corresponding to the cold channel is the difference between the temperature inside the cold channel and the set temperature, the second difference corresponding to the cold channel is the difference between the average value of the temperatures inside all cold channels and the set temperature, the third difference corresponding to the cold channel is the difference between the humidity inside the cold channel and the set humidity, and the fourth difference corresponding to the cold channel is the difference between the average value of the humidity inside all cold channels and the set humidity.

[0023] In the above scheme, the greater the first difference between the measured temperature inside the cold aisle and the set temperature, the greater the amount of cold air required by the cold aisle, the greater the second difference between the average value of the measured temperatures inside all cold aisles and the set temperature, the greater the amount of cold air required by all cold aisles as a whole; in addition, the greater the third difference between the measured humidity inside the cold aisle and the set humidity, the greater the amount of cold air required by the cold aisle, the greater the fourth difference between the average value of the measured humidity inside all cold aisles and the set humidity, the greater the amount of cold air required by all cold aisles as a whole. Therefore, by determining the above-mentioned first difference and second difference, and then determining the ratio of the first difference to the second difference, the ratio accurately represents how to adjust the preset wind pressure of the corresponding cold aisle based on temperature; by determining the above-mentioned third difference and fourth difference, and then determining the ratio of the third difference to the fourth difference, the ratio accurately represents how to adjust the preset wind pressure of the corresponding cold aisle based on humidity; the larger ratio is selected from the above-mentioned two ratios as the final first adjustment coefficient.

[0024] In some optional implementations, the wind pressure determination module is specifically configured to:

[0025] The product of the first adjustment coefficient corresponding to the cold channel and the preset wind pressure is determined as the target wind pressure corresponding to the entrance of the cold channel.

[0026] In some optional implementations, the adjustment coefficient determination module is further configured to:

[0027] For any cabinet corresponding to the cold aisle, determine a second adjustment coefficient corresponding to the cabinet based on the target measurement information of the cabinet, the target measurement information of the cold aisle, and the target setting information; wherein, if the target measurement information of the cold aisle includes the measured temperature inside the cold aisle, and the target setting information includes the set temperature of the air-conditioning unit, then the target measurement information of the cabinet includes the measured temperature corresponding to the cabinet; or, if the target measurement information of the cold aisle includes the measured temperature and humidity inside the cold aisle, and the target setting information includes the set temperature and set humidity of the air-conditioning unit, then the target measurement information of the cabinet includes the measured temperature and humidity corresponding to the cabinet;

[0028] The air valve control module is also used for:

[0029] A target opening of the air valve of the cabinet is determined according to the second adjustment coefficient corresponding to the cabinet and the server configuration rate of the cabinet.

[0030] In the above scheme, since the server configuration ratio of a cabinet represents the heat generation of the cabinet, different cabinets correspond to different temperatures and humidities, and require different amounts of cooling air. Based on the temperature and humidity of the cabinet, the temperature and humidity inside the cold aisle, and the target setting information, the second adjustment coefficient of the cold aisle is determined. Then, based on the second adjustment coefficient and the server configuration ratio of the cabinet, the target opening of the cabinet's air valve is accurately determined, thereby rationally distributing the cooling air to each cabinet.

[0031] In some optional implementations, if the target measurement information of the cold aisle includes the measured temperature inside the cold aisle, the target setting information includes the set temperature of the air-conditioning unit, and the target measurement information of the cabinet includes the measured temperature corresponding to the cabinet, the adjustment coefficient determination module is specifically configured to:

[0032] Determining a fifth difference between the temperature corresponding to the cabinet and the set temperature, and a sixth difference between the temperature inside the cold aisle and the set temperature;

[0033] The ratio of the fifth difference value to the sixth difference value corresponding to the cabinet is determined as the second adjustment coefficient corresponding to the cabinet.

[0034] In the above scheme, the greater the fifth difference between the temperature corresponding to the cabinet and the above set temperature, the greater the amount of cooling air required by the cabinet, and the greater the sixth difference between the measured temperature inside the corresponding cold channel and the above set temperature, the greater the overall cooling air required by all cabinets in the cold channel; therefore, by determining the above fifth difference and sixth difference, and then determining the ratio of the fifth difference to the above sixth difference, the ratio accurately represents how to adjust the air valve opening of the cabinet based on temperature.

[0035] In some optional implementations, if the target measurement information of the cold aisle includes the measured temperature and humidity inside the cold aisle, the target setting information includes the set temperature and set humidity of the air-conditioning unit, and the target measurement information of the cabinet includes the measured temperature and humidity corresponding to the cabinet, then the adjustment coefficient determination module is specifically configured to:

[0036] Selecting a larger ratio from a ratio of the fifth difference to the sixth difference corresponding to the cabinet and a ratio of the seventh difference to the eighth difference corresponding to the cabinet as a second adjustment coefficient corresponding to the cabinet;

[0037] Among them, the fifth difference corresponding to the cabinet is the difference between the temperature corresponding to the cabinet and the set temperature, the sixth difference corresponding to the cabinet is the difference between the temperature inside the cold channel and the set temperature, the seventh difference corresponding to the cabinet is the difference between the humidity corresponding to the cabinet and the set humidity, and the eighth difference corresponding to the cabinet is the difference between the humidity inside the cold channel and the set humidity.

[0038] In the above scheme, the greater the fifth difference between the temperature corresponding to the cabinet and the above-mentioned set temperature, the greater the amount of cooling required by the cabinet, the greater the sixth difference between the measured temperature inside the corresponding cold aisle and the above-mentioned set temperature, and the greater the overall cooling required by all cabinets in the cold aisle; in addition, the greater the seventh difference between the humidity corresponding to the cabinet and the above-mentioned set humidity, the greater the amount of cooling required by the cabinet, and the greater the eighth difference between the measured humidity inside the corresponding cold aisle and the above-mentioned set humidity, the greater the overall cooling required by all cabinets in the cold aisle. Therefore, by determining the above-mentioned fifth and sixth differences, and then determining the ratio of the fifth difference to the sixth difference, this ratio accurately represents how to adjust the cabinet's air valve opening based on temperature; by determining the above-mentioned seventh and eighth differences, and then determining the ratio of the seventh difference to the eighth difference, this ratio accurately represents how to adjust the cabinet's air valve opening based on humidity; and the larger ratio is selected from the above-mentioned two ratios as the final second adjustment coefficient.

[0039] In some optional implementations, the air valve control module is specifically configured to:

[0040] The product of the second adjustment coefficient corresponding to the cabinet and the server configuration rate of the cabinet is used as the target opening of the air valve of the cabinet.

[0043] Determining a target air pressure corresponding to an inlet of the cold aisle according to a first adjustment coefficient corresponding to the cold aisle and a preset air pressure;

[0044] Comparing the measured wind pressure at the entrance of the cold aisle with the corresponding target wind pressure;

[0045] Based on the comparison results, the opening of the air valve at the entrance of the cold channel is adjusted; wherein, the entrance of the cold channel is used to input the cold air provided by the air-conditioning unit into the interior of the cold channel, and the air valve at the entrance is used to adjust the amount of cold air input into the interior of the cold channel.

[0046] In some optional implementations, adjusting the opening of the air valve at the entrance of the cold channel based on the comparison result includes:

[0047] If the measured wind pressure is less than the corresponding target wind pressure, increasing the air valve opening to increase the amount of cold air input into the cold aisle;

[0078] To make the objectives, technical solutions, and advantages of this application more clear, this application will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0079] Servers in data centers generate a significant amount of heat during operation, requiring cooling air from the air conditioning system to meet the server's cooling requirements. In some embodiments, the cooling air output from the air conditioning system is distributed evenly across the cold aisles, ensuring that the amount of cooling air entering each cold aisle is essentially the same.

[0080] However, the servers in the data center are not evenly distributed, and the heat generated by different servers is also different. For example, the remote load is large and the near-end load is small. If the cold air is distributed more evenly to each cold channel, some servers will not meet the heat dissipation requirements. For example, if the remote load is large, the remote server cannot meet the heat dissipation requirements, and if the near-end load is small, the near-end server generates some unnecessary cooling power consumption, the air conditioning energy consumption is high, and the energy efficiency of the data center is affected.

[0081] In view of this, embodiments of the present application provide a temperature adjustment device, method, and computing equipment to more reasonably distribute cold air to each cold channel, thereby reducing the occurrence of situations where servers cannot meet heat dissipation requirements. The method includes: for any cold aisle of a data center, determining a first adjustment coefficient corresponding to the cold aisle according to target measurement information of the cold aisle, an average value of target measurement information of all cold aisles of the data center, and target setting information of an air-conditioning unit of the data center; wherein the target measurement information of the cold aisle includes a measured temperature inside the cold aisle, and the target setting information includes a set temperature of the air-conditioning unit; or, the target measurement information of the cold aisle includes a measured temperature and humidity inside the cold aisle, and the target setting information includes a set temperature and a set humidity of the air-conditioning unit; determining a target air pressure corresponding to an inlet of the cold aisle according to the first adjustment coefficient corresponding to the cold aisle and a preset air pressure; comparing the measured air pressure at the inlet of the cold aisle with the corresponding target air pressure; and adjusting the opening of an air valve at the inlet of the cold aisle based on the comparison result; wherein the inlet of the cold aisle is used to input cold air provided by the air-conditioning unit into the interior of the cold aisle, and the air valve at the inlet is used to adjust the amount of cold air input into the interior of the cold aisle.

[0082] See Figure 1 As shown, an application scenario provided by this embodiment includes: multiple closed units ( Figure 1 The following description uses four enclosed units, namely, enclosed unit 100, enclosed unit 200, enclosed unit 300, and enclosed unit 400, as examples. However, in actual applications, the data center may have more or fewer enclosed units), computing equipment 500, and air-conditioning unit 600.

[0085] The closed unit 200 includes a cold channel 210, and servers 221, 222, 223, 224, 225, 226, and 227;

[0089] Each cold channel is provided with at least one measuring sensor for measuring target information inside the cold channel. The number of measuring sensors in different cold channels can be the same or different.

[0090] The air conditioning unit 600 includes multiple air conditioners ( Figure 1 Six air conditioners, air conditioner 610, air conditioner 620, air conditioner 630, air conditioner 640, air conditioner 650, and air conditioner 660, are used as examples for explanation, but in actual applications, the air conditioning unit can be equipped with more or fewer air conditioners. The control unit in the air conditioning unit 600 can control the operation of part or all of the air conditioners. The working air conditioners provide cold air, and the cold air is transmitted to the cold channel entrance through the static pressure box (not shown in the figure) corresponding to each cold channel; the entrance of the cold channel is used to input the cold air provided by the above-mentioned air conditioning unit 600 into the interior of the cold channel, and the entrance of each cold channel is provided with an air valve (not shown in the figure) for adjusting the amount of cold air input into the interior of the cold channel. A wind pressure sensor is provided at the wind valve position to collect the measured wind pressure at the entrance of the cold channel.

[0091] The computing device 500 may determine, for any of the cold aisles, a first adjustment coefficient corresponding to the cold aisle based on target measurement information of the cold aisle, an average of target measurement information of all cold aisles in the data center, and target setting information of the air-conditioning units in the data center; wherein the target measurement information of the cold aisle includes the measured temperature inside the cold aisle, and the target setting information includes the set temperature of the air-conditioning unit; or, the target measurement information of the cold aisle includes the measured temperature and humidity inside the cold aisle, and the target setting information includes the set temperature and set humidity of the air-conditioning unit; determine a target air pressure corresponding to the inlet of the cold aisle based on the first adjustment coefficient corresponding to the cold aisle and a preset air pressure; compare the measured air pressure at the inlet of the cold aisle with the corresponding target air pressure; and adjust the opening of the air valve at the inlet of the cold aisle based on the comparison result; wherein the inlet of the cold aisle is used to input the cold air provided by the air-conditioning unit into the interior of the cold aisle, and the air valve at the inlet is used to adjust the amount of cold air input into the interior of the cold aisle.

[0092] The above application scenarios are only exemplary descriptions, and the embodiments of the present application are not limited thereto. For example, the number of closed units in the data center, the number of servers in each closed unit, the number of measuring sensors in the cold channel, and the positions of the measuring sensors in the cold channel can all be set according to the actual application scenarios.

[0093] The following will be combined with the accompanying drawings and specific embodiments to explain in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0094] The embodiment of the present application provides a first temperature adjustment method, which can be applied to the above computing device, such as Figure 2 As shown, the following steps are included:

[0095] Step S201: For any cold aisle of a data center, determine a first adjustment coefficient corresponding to the cold aisle based on target measurement information of the cold aisle, an average value of target measurement information of all cold aisles of the data center, and target setting information of air conditioning units of the data center.

[0096] The target measurement information of the cold channel includes the measured temperature inside the cold channel, and the target setting information includes the set temperature of the air-conditioning unit; or the target measurement information of the cold channel includes the measured temperature and humidity inside the cold channel, and the target setting information includes the set temperature and set humidity of the air-conditioning unit.

[0097] In this embodiment, the data center is equipped with multiple enclosed units. Since the temperature and humidity within the cold aisles of each enclosed unit reflect the temperature and humidity conditions surrounding the servers within that unit, different temperatures and humidity conditions surrounding the servers require different amounts of cooling air. Furthermore, the target setting information represents the cooling provided by the air conditioning units and also affects the amount of cooling air supplied to the cold aisles. Therefore, based on the temperature and humidity within the cold aisles, the temperature and humidity within all cold aisles in the data center, and the set temperature and humidity of the air conditioning units, a first adjustment coefficient can be determined that indicates how to adjust the preset air pressure of the corresponding cold aisle based on the temperature and humidity.

[0098] As mentioned above, the target measurement information is determined by the information collected by the measurement sensor, so the specific content of the target measurement information is determined by the type of measurement sensor. For example:

[0099] If the measuring sensor is a temperature sensor, the target measurement information includes the measured temperature;

[0100] If the measurement sensor is a temperature and humidity sensor, the target measurement information includes the measured temperature and humidity.

[0101] Reference Figure 1 As shown, each cold aisle is provided with at least one measurement sensor, and the number of measurement sensors in different cold aisles can be the same or different. If multiple measurement sensors are provided in a cold aisle, the target measurement information of the cold aisle can be determined based on the measurement information of the multiple measurement sensors in the cold aisle, such as:

[0102] determining an average value of measurement information of the plurality of measurement sensors as target measurement information of the cold channel;

[0103] determining a maximum value of measurement information of the plurality of measurement sensors as target measurement information of the cold channel;

[0104] A minimum value of the measurement information of the plurality of measurement sensors is determined as the target measurement information of the cold channel.

[0105] In addition, if Figure 1 As shown, servers may be unevenly distributed within a closed unit. If the measurement sensors are randomly positioned, the target measurement information obtained from the measurement sensors may not accurately reflect the temperature and humidity conditions around the servers. Therefore, in some optional implementations, the measurement sensors are positioned based on the locations of the servers corresponding to the cold aisles. For example, the measurement sensors can be placed in areas with a high concentration of servers.

[0106] In some specific implementations, the computing device may also need to send target measurement information of all cold aisles to the air conditioning units, so that the air conditioning units determine the air conditioners that need to be operated in the air conditioning units and target setting information for these air conditioners based on the received target measurement information. These air conditioners then output cold air based on the target setting information. For example:

[0107] The control unit of the air conditioning unit determines the number of air conditioners that need to be operated based on the target measurement information. For example, if the temperature inside each cold aisle is relatively high, all air conditioners need to be operated; if the temperature inside most cold aisles is relatively low, only some air conditioners need to be operated, etc.

[0108] The above-mentioned control unit determines the target setting information of the air conditioners that need to work based on the target measurement information and the number of air conditioners that need to work. For example, the higher the overall temperature inside the cold channel, the lower the set temperature of the output cold air; the higher the overall humidity inside the cold channel, the lower the set humidity of the output cold air, and so on.

[0109] Of course, the air-conditioning unit may also determine the target setting information of the air conditioner that needs to be operated in other ways, which will not be described here.

[0110] Step S202: determining a target air pressure corresponding to the inlet of the cold aisle according to a first adjustment coefficient corresponding to the cold aisle and a preset air pressure.

[0111] In this embodiment, the longer the cold aisle duct, the greater the wind resistance, and therefore the higher the wind pressure required to deliver cold air into the cold aisle. Therefore, the preset wind pressure required to deliver cold air into the cold aisle is determined based on the cold aisle duct length. The preset wind pressure is then adjusted based on the first adjustment coefficient to determine a target wind pressure that can deliver cold air into the cold aisle and meet the cold aisle's cooling requirements.

[0112] In this embodiment, the target air pressure corresponding to the entrance of the cold aisle can be determined by, but not limited to, the following methods:

[0113] The product of the first adjustment coefficient corresponding to the cold channel and the preset wind pressure is determined as the target wind pressure corresponding to the entrance of the cold channel.

[0114] Step S203: comparing the measured wind pressure at the entrance of the cold aisle with the corresponding target wind pressure.

[0115] In this embodiment, the target air pressure represents the cold aisle's demand for cooling air. The measured air pressure, collected by a pressure sensor at the damper location, represents the cold aisle's cooling air input. Based on this, the measured air pressure is compared with the corresponding target air pressure, and the adjustment of the damper opening at the cold aisle's entrance is determined based on the comparison result.

[0116] Step S204: Based on the comparison result, adjust the opening of the air valve at the entrance of the cold channel.

[0117] The inlet of the cold channel is used to input the cold air provided by the air conditioning unit of the data center into the cold channel, and the air valve at the inlet is used to adjust the amount of cold air input into the cold channel.

[0118] Adjusting the opening of the air valve at the entrance of the cold channel based on the comparison results can be achieved by, but not limited to, the following methods:

[0119] If the measured wind pressure is less than the corresponding target wind pressure, increasing the air valve opening to increase the amount of cold air input into the cold aisle;

[0120] If the measured wind pressure is greater than the corresponding target wind pressure, the air valve opening is reduced to reduce the amount of cold air input into the cold channel.

[0121] It can be understood that if the measured wind pressure is equal to the corresponding target wind pressure, there is no need to adjust the air valve opening, that is, the current amount of cold air input into the cold channel just meets the current demand of the cold channel.

[0122] Since the target wind pressure represents the demand for cold air in the cold channel, the measured wind pressure represents the input of cold air in the cold channel. If the measured wind pressure is lower than the corresponding target wind pressure, it means that the amount of cold air input into the cold channel cannot meet the demand of the cold channel. By increasing the air valve opening, the amount of cold air input into the cold channel is increased, and the situation where the servers corresponding to these cold channels cannot meet the heat dissipation requirements is reduced. If the measured wind pressure is higher than the corresponding target wind pressure, it means that the amount of cold air input into the cold channel exceeds the demand of the cold channel. By reducing the air valve opening, the amount of cold air input into the cold channel is reduced, and the unnecessary cooling power consumption of the servers corresponding to these cold channels is reduced, making the air conditioner run efficiently.

[0123] In the above scheme, since the temperature and humidity inside different cold channels of the data center are different, the required amount of cooling air is different. Based on the temperature and humidity inside the cold channel, the temperature and humidity inside all cold channels of the data center, and the target setting information of the air-conditioning unit, the first adjustment coefficient of the cold channel is determined; then, the preset wind pressure of the cold channel is adjusted based on the first adjustment coefficient to obtain the target wind pressure at the entrance of the cold channel; according to the above target wind pressure (the target wind pressure represents the demand for cooling air in the cold channel) and the measured wind pressure (the measured wind pressure represents the input of cooling air in the cold channel), the valve opening at the entrance of the cold channel is adjusted, so that based on the different demand for cooling air in each cold channel, the amount of cooling air input to each cold channel is adjusted in a targeted manner, and the cooling air is more reasonably distributed to each cold channel of the data center, reducing the occurrence of servers failing to meet the heat dissipation requirements.

[0124] The target measurement information for the cold channel includes the measured temperature inside the cold channel, and the target setting information includes the set temperature of the air-conditioning unit. The embodiment of the present application provides a second temperature adjustment method, which can be applied to the above-mentioned computing device, such as Figure 3 As shown, the following steps are included:

[0125] Step S301: for any cold aisle of a data center, determining a first difference between the temperature inside the cold aisle and the set temperature, and a second difference between the average of the temperatures inside all cold aisles and the set temperature.

[0126] Step S302: Determine the ratio of the first difference value corresponding to the cold channel to the second difference value as the first adjustment coefficient corresponding to the cold channel.

[0127] In this embodiment, the greater the first difference between the measured temperature inside a cold aisle and the set temperature, the greater the cooling capacity required for that cold aisle. The greater the second difference between the average measured temperature inside all cold aisles and the set temperature, the greater the cooling capacity required for all cold aisles as a whole. By determining the ratio of the first difference to the second difference, this ratio accurately indicates how to adjust the preset air pressure of the corresponding cold aisle based on temperature.

[0128] For example, λ is the first adjustment coefficient, T i is the measured temperature inside the cold aisle i, is the average measured temperature inside all cold aisles, and T0 is the set temperature.

[0129] Step S303: determining a target air pressure corresponding to the inlet of the cold aisle according to the first adjustment coefficient corresponding to the cold aisle and the preset air pressure.

[0130] Step S304: comparing the measured wind pressure at the entrance of the cold aisle with the corresponding target wind pressure.

[0131] Step S305: Based on the comparison result, adjust the opening of the air valve at the entrance of the cold channel.

[0132] The inlet of the cold channel is used to input the cold air provided by the air conditioning unit of the data center into the cold channel, and the air valve at the inlet is used to adjust the amount of cold air input into the cold channel.

[0133] The specific implementation of steps S303 - 305 may refer to the above embodiment and will not be described again here.

[0134] The target measurement information for the cold channel includes the measured temperature and humidity inside the cold channel, and the target setting information includes the set temperature and set humidity of the air-conditioning unit. The embodiment of the present application provides a third temperature adjustment method, which can be applied to the above-mentioned computing device, such as Figure 4 As shown, the following steps are included:

[0135] Step S401: Selecting a larger ratio from among a ratio of a first difference to a second difference corresponding to the cold aisle and a ratio of a third difference to a fourth difference corresponding to the cold aisle as a first adjustment coefficient corresponding to the cold aisle.

[0136] Among them, the first difference corresponding to the cold channel is the difference between the temperature inside the cold channel and the set temperature, the second difference corresponding to the cold channel is the difference between the average value of the temperatures inside all cold channels and the set temperature, the third difference corresponding to the cold channel is the difference between the humidity inside the cold channel and the set humidity, and the fourth difference corresponding to the cold channel is the difference between the average value of the humidity inside all cold channels and the set humidity.

[0137] In this embodiment, the greater the first difference between the measured temperature inside the cold aisle and the above-mentioned set temperature, the greater the amount of cold air required by the cold aisle; the greater the second difference between the average value of the measured temperatures inside all cold aisles and the above-mentioned set temperature, the greater the amount of cold air required by all cold aisles as a whole; the greater the third difference between the measured humidity inside the cold aisle and the above-mentioned set humidity, the greater the amount of cold air required by the cold aisle; the greater the fourth difference between the average value of the measured humidity inside all cold aisles and the above-mentioned set humidity, the greater the amount of cold air required by all cold aisles as a whole.

[0138] By determining a ratio of the first difference to the second difference, the ratio represents how to adjust the preset air pressure of the corresponding cold channel based on the temperature;

[0139] By determining a ratio of the third difference to the fourth difference, the ratio indicates how to adjust the preset air pressure of the corresponding cold aisle based on the humidity;

[0140] Then, the larger ratio is selected from the above two ratios as the final first adjustment coefficient.

[0141] For example, λ T is the ratio of the first difference to the second difference, which represents how to adjust the preset air pressure of the corresponding cold channel based on the temperature. i is the measured temperature inside the cold aisle i, is the average value of the measured temperature inside all cold aisles, and T0 is the set temperature;

[0142] λH is the ratio of the third difference to the fourth difference, which represents how to adjust the preset air pressure of the corresponding cold channel based on humidity. i is the measured humidity inside the cold aisle i, is the average measured humidity inside all cold aisles, and H0 is the set humidity;

[0143] From λ T and λ H The larger one is selected as the final first adjustment coefficient, that is, if λ T ≥λ H , change λ T As the final first adjustment coefficient, if λ T <λ H , change λ H As the final first adjustment coefficient.

[0144] Step S402: determining a target air pressure corresponding to an inlet of the cold aisle according to a first adjustment coefficient corresponding to the cold aisle and a preset air pressure.

[0145] Step S403: comparing the measured wind pressure at the entrance of the cold aisle with the corresponding target wind pressure.

[0146] Step S404: Based on the comparison result, adjust the opening of the air valve at the entrance of the cold channel.

[0147] The inlet of the cold channel is used to input the cold air provided by the air-conditioning unit into the inside of the cold channel, and the air valve at the inlet is used to adjust the amount of cold air input into the inside of the cold channel.

[0148] The specific implementation of steps S402-404 can refer to the above embodiment and will not be repeated here.

[0149] In some optional embodiments, in addition to setting an air valve at the entrance of the cold channel, an air valve is also set at each cabinet corresponding to the cold channel. For example, if the bottom of the cabinet is an elevated floor, the air valve is set at the bottom of the cabinet. The cold air provided by the air conditioner can pass through the gap between the bottom of the cabinet and the elevated floor and enter the cabinet through the air valve of the cabinet.

[0150] For any cabinet corresponding to the cold aisle, a second adjustment coefficient corresponding to the cabinet may be determined according to the target measurement information of the cabinet, the target measurement information of the cold aisle, and the target setting information;

[0151] A target opening of the air valve of the cabinet is determined according to the second adjustment coefficient corresponding to the cabinet and the server configuration rate of the cabinet.

[0152] Wherein, if the target measurement information of the cold aisle includes the measured temperature inside the cold aisle, and the target setting information includes the set temperature of the air-conditioning unit, then the target measurement information of the cabinet includes the measured temperature corresponding to the cabinet;

[0153] Alternatively, if the target measurement information of the cold channel includes the measured temperature and humidity inside the cold channel, and the target setting information includes the set temperature and set humidity of the air-conditioning unit, then the target measurement information of the cabinet includes the measured temperature and humidity corresponding to the cabinet.

[0154] In this embodiment, the server configuration rate refers to the ratio of the number of servers currently configured in the cabinet to the maximum number of servers that can be configured in the cabinet.

[0155] The target opening of the cabinet's air valve can be determined by, but not limited to, the following methods:

[0156] The product of the second adjustment coefficient corresponding to the cabinet and the server configuration rate of the cabinet is used as the target opening of the air valve of the cabinet.

[0157] During implementation, if the current opening of the air valve of the cabinet is the same as the target opening, there is no need to adjust the air valve of the cabinet; if the current opening of the air valve of the cabinet is different from the target opening, the air valve of the cabinet is adjusted to the target opening.

[0158] The second adjustment coefficient corresponding to the cabinet can be determined in the following two ways, but is not limited to:

[0159] The first method

[0160] The target measurement information of the cold channel includes the measured temperature inside the cold channel, the target setting information includes the set temperature of the air-conditioning unit, and the target measurement information of the cabinet includes the measured temperature corresponding to the cabinet.

[0161] For any cabinet corresponding to the cold aisle, determining a fifth difference between the temperature corresponding to the cabinet and the set temperature, and a sixth difference between the temperature inside the cold aisle and the set temperature;

[0162] The ratio of the fifth difference value to the sixth difference value corresponding to the cabinet is determined as the second adjustment coefficient corresponding to the cabinet.

[0163] Since the greater the fifth difference between the temperature corresponding to the cabinet and the above-mentioned set temperature, the greater the amount of cooling air required by the cabinet, and the greater the sixth difference between the measured temperature inside the corresponding cold aisle and the above-mentioned set temperature, the greater the overall cooling air required by all cabinets in the cold aisle.

[0164] Based on this, this embodiment determines the fifth difference and the sixth difference, and then determines the ratio of the fifth difference to the sixth difference. The ratio accurately represents how to adjust the air valve opening of the cabinet based on temperature.

[0165] For example, β is the second adjustment coefficient, t i is the temperature corresponding to cabinet j in cold aisle i, T i is the measured temperature inside the cold channel i, and T0 is the set temperature.

[0166] Second method

[0167] The target measurement information of the cold channel includes the measured temperature and humidity inside the cold channel, the target setting information includes the set temperature and set humidity of the air-conditioning unit, and the target measurement information of the cabinet includes the measured temperature and humidity corresponding to the cabinet.

[0168] For any cabinet corresponding to the cold aisle, the difference between the temperature corresponding to the cabinet and the set temperature is used as the fifth difference corresponding to the cabinet, the difference between the temperature inside the cold aisle and the set temperature is used as the sixth difference corresponding to the cabinet, the difference between the humidity corresponding to the cabinet and the set humidity is used as the seventh difference corresponding to the cabinet, and the difference between the humidity inside the cold aisle and the set humidity is used as the eighth difference corresponding to the cabinet;

[0169] Determine the ratio of the fifth difference to the sixth difference corresponding to the cabinet, and the ratio of the seventh difference to the eighth difference corresponding to the cabinet respectively; and from the ratio of the fifth difference to the sixth difference corresponding to the cabinet, and the ratio of the seventh difference to the eighth difference corresponding to the cabinet, select the larger ratio as the second adjustment coefficient corresponding to the cabinet.

[0170] The greater the fifth difference between the temperature corresponding to the cabinet and the set temperature, the greater the amount of cooling air required by the cabinet. The greater the sixth difference between the measured temperature inside the cold aisle and the set temperature, the greater the overall cooling air required by all cabinets in the cold aisle.

[0171] The greater the seventh difference between the humidity corresponding to the cabinet and the above-mentioned set humidity, the greater the amount of cooling required by the cabinet. The greater the eighth difference between the measured humidity inside the corresponding cold aisle and the above-mentioned set humidity, the greater the overall cooling required by all cabinets in the cold aisle.

[0172] Based on this, this embodiment determines the fifth difference and the sixth difference, and then determines the ratio of the fifth difference to the sixth difference. This ratio accurately represents how to adjust the air valve opening of the corresponding cabinet based on the temperature.

[0173] By determining the seventh difference and the eighth difference, a ratio of the seventh difference to the eighth difference is determined, where the ratio accurately represents how to adjust the air valve opening of the corresponding cabinet based on the humidity;

[0174] Then, the larger ratio is selected from the above two ratios as the final second adjustment coefficient.

[0175] For example, β T is the ratio of the fifth difference to the sixth difference, which represents how to adjust the air valve opening of the corresponding cabinet based on temperature. i is the temperature corresponding to cabinet j in cold aisle i, T i is the measured temperature inside the cold aisle i, and T0 is the set temperature;

[0176] β H is the ratio of the seventh difference to the eighth difference, which represents how to adjust the air valve opening of the corresponding cabinet based on humidity, h i is the humidity corresponding to cabinet j in cold aisle i, T i is the measured humidity inside cold aisle i, and T0 is the set humidity;

[0177] From β T and β H The larger one is selected as the final second adjustment coefficient, that is, if β T ≥β H , β T As the final second adjustment coefficient, if β T <β H , β H As the final second adjustment coefficient.

[0178] Because the air conditioning unit contains multiple air conditioners, operating simultaneously can easily cause return air short-circuiting. To prevent this, in some optional embodiments, a check valve can be installed at the top or bottom of each air conditioner, or the air conditioner's fan speed can be controlled within a threshold.
