Description

Technical Field

[0001] The present application relates to the field of refrigeration technology, and in particular to a data center control method, system and storage medium. Background Art

[0002] With the booming development of the digital economy, data center equipment is playing an increasingly important role because it can be used to store massive amounts of data. In order to ensure the reliability of data center equipment operation, the data center equipment can be placed in a confined space, and the confined space is in a semi-enclosed space with an inlet and an outlet, which can prevent the outside world from corroding the data center equipment to a certain extent.

[0003] Specifically, in order to prevent the ambient temperature of the data center equipment from being too high and causing malfunctions (such as circuit burnout and short circuit), it is necessary to further control the operation of the air intake system at the entrance of the semi-enclosed space and the operation of the exhaust system at the exit of the semi-enclosed space, so that the entrance of the semi-enclosed space maintains a positive pressure relative to the exit of the semi-enclosed space. In this way, the air intake system can inhale outside air into the air conditioner, and the air conditioner performs heat exchange to reduce the temperature of the data center equipment located in the enclosed space, and then use the exhaust system to discharge the hot air discharged by the air conditioner to the outside.

[0004] However, when the seal of the enclosed space is not tight enough, the hot and humid air sucked by the air intake system can easily penetrate into the enclosed space, bringing dehumidification load and heat load to the enclosed space, which is not energy-saving and environmentally friendly. Summary of the invention

[0029] When the difference between the third air pressure difference ΔP3 and the preset third target value is greater than the set difference threshold, the controller controls the alarm to sound an alarm.

[0030] Under normal circumstances, the first air pressure P 进风口 With the third air pressure P 排风口 The third pressure difference ΔP3 between the two should reach the third target value. The third target value is greater than 0. When the difference between the third pressure difference ΔP3 and the preset third target value is greater than 0, it indicates that there is an abnormality in the control of the air intake system and / or the exhaust system.

[0031] In a second aspect, the present application further provides a data center control system, the data center control system is in a data center refrigeration space, the data center refrigeration space includes: a closed room with data center equipment, and a semi-closed space with an air inlet and an air outlet, the closed room is located in the semi-closed space and forms a ventilation duct with the inner wall of the semi-closed space, the data center control system includes a controller, an air intake system and a first air pressure sensor arranged at the air inlet, an air conditioner and a second air pressure sensor arranged in the closed room, an exhaust system and a third air pressure sensor arranged at the exhaust outlet,

[0032] The first air pressure sensor is used to collect the first air pressure at the air inlet, the second air pressure sensor is used to collect the second air pressure in the closed room, and the third air pressure sensor is used to collect the third air pressure at the air outlet;

[0033] a controller for receiving a first air pressure from a first air pressure sensor, a second air pressure from a second air pressure sensor, and a third air pressure from a third air pressure sensor;

[0035] In a possible implementation manner, when the adjustment mode is incremental adjustment, the controller is specifically configured to adjust the pressure according to the second air pressure P 密闭室内 and the first air pressure P 进风口 , using the first formula:

[0036] ΔP1=P 密闭室内 -P 进风口

[0037] Determining a first air pressure difference ΔP1;

[0038] Controlling the air intake system to adjust the operating power so that the first air pressure difference ΔP1 reaches a first target value;

[0049] When the second air pressure difference ΔP2 is higher than the second target value, the exhaust system is controlled to reduce the operating power until the first air pressure difference ΔP2 reaches the second target value.

[0050] In a third aspect, the present application further provides a computer-readable storage medium, in which computer-executable instructions are stored. When the computer-executable instructions are executed by a processor, they are used to implement the method provided in the first aspect of the present application.

[0051] In a fourth aspect, the present application further provides a computer program product, comprising a computer program, which, when executed, enables a computer to execute the method provided in the first aspect of the present application.

[0052] The present application provides a data center control method, system and storage medium. The embodiment of the present application provides a data center control method, wherein a controller can receive a first air pressure at an air inlet collected by a first air pressure sensor, a second air pressure in a closed room collected by a second air pressure sensor, and a third air pressure at an air outlet collected by a third air pressure sensor;

[0053] Furthermore, the controller adjusts the power of the air intake system and the power of the air exhaust system according to the first air pressure, the second air pressure and the third air pressure, respectively, so that the first air pressure is greater than the third air pressure, and the second air pressure is greater than the first air pressure. That is to say, the air pressure at the air inlet is greater than the air pressure at the air outlet, so that a positive pressure difference is formed between the air pressure at the air inlet and the air pressure at the air outlet, so that the air outside the semi-enclosed space can be smoothly sucked into the ventilation duct outside the enclosed room through the air inlet, so that the air conditioner can perform heat exchange with the air in the ventilation duct to cool the multiple data center equipment in the enclosed room, and smoothly output the hot air to the exhaust duct through the ventilation duct outside the enclosed room to complete the refrigeration cycle;

[0054] In addition, the air pressure in the closed room is also made greater than the air pressure at the air inlet. In this way, since the air pressure in the closed room is greater than the air pressure at the air inlet, and the air pressure at the air inlet is greater than the air pressure at the air outlet, it can be deduced that the air pressure in the closed room is also greater than the air pressure at the air outlet. In this way, the air pressure in the closed room is greater than both the air pressure at the air inlet and the air outlet, that is, the closed room forms a positive pressure difference relative to the air inlet and the air outlet, respectively. Even if the seal of the closed room is not tight enough, the hot and humid air sucked by the air intake system (whether at the air inlet or the air outlet) is not easy to penetrate into the closed space, saving the dehumidification load and heat load of the closed room, saving energy and protecting the environment.

[0055] Furthermore, each sealed room is equipped with an inlet and outlet. If the pressure difference between the sealed room and the sealed room of the data center cooling space is too large, the inlet and outlet will be difficult to open. The sealed room forms a positive pressure difference with respect to the air inlet and the air outlet, and the air inlet and the air outlet maintain a positive pressure difference, that is, the formula P is maintained. 进风口 -P 排风口 The third pressure difference ΔP3 between them is greater than 0, and the formula ΔP1=P 密闭室内 -P 进风口 The first pressure difference ΔP1 between them is greater than 0, ΔP2=P 密闭室内 -P 排风口 The second air pressure difference ΔP2 between them is greater than 0.

[0056] If we want to keep the formula P 进风口 -P 排风口 The third pressure difference ΔP3 between them is greater than 0, and the formula ΔP1=P 密闭室内 -P 进风口 The first pressure difference ΔP1 between them is greater than 0, ΔP2=P 密闭室内 -P 排风口 The second pressure difference ΔP2 between the two is greater than 0, then the pressure P in the closed room 密闭室内 , air pressure at the air inlet P 进风口 , the air pressure at the exhaust port P 排风口 The difference between the two is small, which makes the air pressure in each location of the data center cooling space (such as the air inlet, exhaust outlet, and closed room) more uniform. In this way, the entrance and exit doors set in each closed space are easier to open, making it convenient for staff to enter and exit. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments made by ordinary technicians in this field under the enlightenment of the embodiments belong to the scope of protection of the present application.

[0062] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0063] With the booming development of the digital economy, data center equipment is playing an increasingly important role because it can be used to store massive amounts of data. In order to ensure the reliability of data center equipment operation, the data center equipment can be placed in a confined space, and the confined space is in a semi-enclosed space with an inlet and an outlet, which can prevent the outside from corroding the data center equipment to a certain extent. However, when the confined space is not sealed tightly enough, the hot and humid air sucked in by the air intake system can easily penetrate into the confined space, bringing dehumidification load and heat load to the confined space, which is not energy-saving and environmentally friendly.

[0064] Based on the above technical problems, the invention of this application is to ensure that the pressure difference between the air inlet and the air outlet is positive while making the pressure difference between the inside and outside of the enclosed space also positive. In this way, when the seal of the enclosed space is not tight enough, the hot and humid air sucked by the air intake system is not easy to penetrate into the enclosed space, saving the dehumidification load and heat load of the enclosed space, saving energy and protecting the environment.

[0065] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. 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. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0066] The present application embodiment provides a data center control method, which is applied to a data center control system in a refrigeration space of a data center. Figure 1 As shown, the data center cooling space includes: a closed room 108 with data center equipment 101 therein, and a semi-closed space with an air inlet 104 and an air outlet 106. The closed room 108 is located in the semi-closed space and forms a ventilation duct 107 (including a cold air duct and a hot air duct) outside the closed room 108 with the inner wall of the semi-closed space; the closed room 108 includes a ventilation duct (also including a cold air duct and a hot air duct) inside the closed room 108, and a plurality of data center equipment 101 are arranged in the closed room 108.

[0067] The data center control system includes a controller 201, an air intake system 103 and a first air pressure sensor 202 arranged at the air inlet 104, an air conditioner 102 and a second air pressure sensor 204 arranged in the closed room 108, and an exhaust system 105 and a third air pressure sensor 203 arranged at the exhaust outlet 106.

[0068] It should be noted that the first air pressure sensor 202, the second air pressure sensor 204 and the third air pressure sensor 203 can be independent sensor modules; alternatively, the first air pressure sensor 202 and the second air pressure sensor 204 are two air pressure sampling modules of the pressure difference sensor A, and the second air pressure sensor 204 and the third air pressure sensor 203 are two air pressure sampling modules of the pressure difference sensor B, which is not limited here.

[0069] Among them, the controller 201 can control the air intake system 103 to suck the air outside the semi-enclosed space into the ventilation duct 107 outside the closed room 108 through the air inlet 104, and the air conditioner 102 exchanges heat with the air in the ventilation duct 107 outside the closed room 108 through the air-to-air heat exchanger of the air conditioner 102, and outputs cold air to the closed room 108 to cool the multiple data center equipment 101 in the closed room 108, and outputs hot air to the exhaust port 106 through the ventilation duct 107 outside the closed room 108, and the controller 201 controls the exhaust system 105 to discharge the hot air out of the semi-enclosed space through the exhaust port 106 to complete the refrigeration cycle.

[0070] like Figure 2 As shown, the controller 201 is electrically connected to the air intake system 103, the first air pressure sensor 202, the air conditioner 102, the second air pressure sensor 204, the exhaust system 105 and the third air pressure sensor 203 respectively. Figure 3 As shown, the method provided in the embodiment of the present application includes:

[0071] S301 : the controller 201 receives a first air pressure at the air inlet 104 collected by the first air pressure sensor 202 , a second air pressure in the sealed chamber 108 collected by the second air pressure sensor 204 , and a third air pressure at the air outlet 106 collected by the third air pressure sensor 203 .

[0072] Optionally, the first air pressure sensor 202, the second air pressure sensor 204, and the third air pressure sensor 203 may be independent sensor modules. Alternatively, the first air pressure sensor 202 may also include multiple first sensor modules located at different positions of the air inlet 104, and the first air pressure value is the average value of the sub-air pressure values ​​collected by the multiple first sensor modules respectively; the second air pressure sensor 204 may also include multiple second sensor modules located at different positions in the closed chamber 108, and the second air pressure value is the average value of the sub-air pressure values ​​collected by the multiple second sensor modules respectively; the third air pressure sensor 203 may also include multiple third sensor modules located at different positions of the air outlet 106, and the third air pressure value is the average value of the sub-air pressure values ​​collected by the multiple third sensor modules respectively. In this way, the reliability of the obtained first air pressure value, second air pressure value, and third air pressure value is higher.

[0073] S302: The controller 201 adjusts the power of the air intake system 103 and the power of the air exhaust system 105 according to the first air pressure, the second air pressure and the third air pressure, respectively, so that the first air pressure is greater than the third air pressure, and the second air pressure is greater than the first air pressure.

[0074] Specifically, in S302, the adjustment method is incremental adjustment, proportional adjustment or PID adjustment.

[0075] For example, when the adjustment mode is incremental adjustment, S302 may be specifically implemented as follows:

[0076] Step 1: The controller 201 controls the air pressure P according to the second air pressure P. 密闭室内 and the first air pressure P 进风口 , using the first formula ΔP1=P 密闭室内 -P 进风口 A first gas pressure difference ΔP1 is determined.

[0077] Step 2: Control the air intake system 103 to adjust the operating power so that the first air pressure difference ΔP1 reaches a first target value.

[0078] It should be noted that step 2 can be specifically implemented as follows: when the first air pressure difference ΔP1 is lower than the first target value, the air intake system 103 is controlled to increase the operating power until the first air pressure difference ΔP1 reaches the first target value. When the first air pressure difference ΔP1 is higher than the first target value, the air intake system 103 is controlled to reduce the operating power until the first air pressure difference ΔP1 reaches the first target value.

[0079] Step 3: The controller 201 controls the air pressure P according to the second air pressure P. 密闭室内 and the third air pressure P 排风口 , using the second formula ΔP2=P 密闭室内 -P 排风口 , determine the second air pressure difference ΔP2.

[0080] Step 4: Control the exhaust system 105 to adjust the operating power so that the second air pressure difference ΔP2 reaches the second target value.

[0081] Among them, the second target value is smaller than the first target value.

[0082] Specifically, step 4 can be implemented as follows: when the second air pressure difference ΔP2 is lower than the second target value, the exhaust system 105 is controlled to increase the operating power until the first air pressure difference ΔP2 reaches the second target value; when the second air pressure difference ΔP2 is higher than the second target value, the exhaust system 105 is controlled to reduce the operating power until the first air pressure difference ΔP2 reaches the second target value.

[0083] It can be understood that based on the above steps 1 to 4, the pressure difference between the air inlet 104 and the air outlet ΔP3 = P 进风口 -P 出风口 =ΔP1-ΔP2. When the first pressure difference ΔP1 reaches the first target value, the second pressure difference ΔP2 reaches the second target value, and the second target value is less than the first target value, ΔP1-ΔP2 is greater than 0, that is, the pressure difference between the air inlet 104 and the air outlet is a positive pressure difference, that is, the first pressure is greater than the third pressure. When the first pressure difference ΔP1 reaches the first target value, the second pressure P 密闭室内 Greater than the first air pressure P 进风口 .

[0084] For example, when the first pressure difference ΔP1 is 10 Pa and the second pressure difference ΔP2 is 5 Pa, ΔP3 = ΔP1 - ΔP2 = 5 Pa, that is, the pressure difference between the air inlet 104 and the air outlet is a positive pressure difference.

[0085] After the above step 4, the method provided in the embodiment of the present application further includes:

[0086] Step 5: According to the formula ΔP3=P 进风口 -P 排风口 , determine the first air pressure P 进风口 With the third air pressure P 排风口 The third air pressure difference ΔP3 between them.

[0087] Step 6: When the difference between the third air pressure difference ΔP3 and the preset third target value is greater than the set difference threshold, the controller 201 controls the alarm to sound an alarm.

[0088] It can be understood that after step 2 to step 4, under normal circumstances, the first air pressure P 进风口 With the third air pressure P 排风口 The third pressure difference ΔP3 between the air intake system 103 and the exhaust system 105 should reach the third target value. The third target value is greater than 0. When the third pressure difference ΔP3 is different from the preset third target value, it indicates that there is an abnormality in the control of the air intake system 103 and / or the exhaust system 105. At this time, the control alarm alarms to prompt the staff to perform maintenance.

[0089] In summary, the embodiment of the present application provides a data center control method, wherein the controller 201 can receive a first air pressure at the air inlet 104 collected by the first air pressure sensor 202, a second air pressure in the closed chamber 108 collected by the second air pressure sensor 204, and a third air pressure at the air outlet 106 collected by the third air pressure sensor 203;

[0090] Furthermore, the controller 201 adjusts the power of the air intake system 103 and the power of the exhaust system 105 according to the first air pressure, the second air pressure and the third air pressure, respectively, so that the first air pressure is greater than the third air pressure, and the second air pressure is greater than the first air pressure. That is to say, the air pressure at the air inlet 104 is greater than the air pressure at the exhaust port 106, so that a positive pressure difference is formed between the air pressure at the air inlet 104 and the air pressure at the exhaust port 106, so that the air outside the semi-enclosed space can be smoothly sucked into the ventilation duct 107 outside the closed room 108 through the air inlet 104, so that the air conditioner 102 can perform heat exchange with the air in the ventilation duct 107 to cool the multiple data center devices 101 in the closed room 108, and smoothly output hot air to the exhaust port 106 through the ventilation duct 107 outside the closed room 108 to complete the refrigeration cycle;

[0091] In addition, the air pressure in the sealed room 108 is also made greater than the air pressure at the air inlet 104. In this way, since the air pressure in the sealed room 108 is greater than the air pressure at the air inlet 104, and the air pressure at the air inlet 104 is greater than the air pressure at the air outlet 106, it can be deduced that the air pressure in the sealed room 108 is also greater than the air pressure at the air outlet 106. In this way, the air pressure in the sealed room 108 is greater than both the air pressure at the air inlet 104 and the air outlet 106, that is, the sealed room 108 forms a positive pressure difference with respect to the air inlet 104 and the air outlet 106, respectively. Even if the sealing of the sealed room 108 is not tight enough, the hot and humid air sucked by the air intake system 103 (whether at the air inlet 104 or at the air outlet 106) is not easy to penetrate into the sealed space, saving the dehumidification load and heat load of the sealed room, and saving energy and protecting the environment.

[0092] Furthermore, each sealed room 108 is provided with an inlet and outlet door. If the pressure difference between the sealed room 108 and the outside of the sealed room 108 of the data center refrigeration space is too large, the inlet and outlet door will be difficult to open. The sealed room 108 forms a positive pressure difference with respect to the air inlet 104 and the air outlet 106, and the air inlet 104 and the air outlet 106 maintain a positive pressure difference, that is, the formula P is maintained. 进风口 -P 排风口 The third pressure difference ΔP3 between them is greater than 0, and the formula ΔP1=P 密闭室内 -P 进风口 The first pressure difference ΔP1 between them is greater than 0, ΔP2=P 密闭室内 -P 排风口 The second air pressure difference ΔP2 between them is greater than 0.

[0093] If we want to keep the formula P 进风口 -P 排风口 The third pressure difference ΔP3 between them is greater than 0, and the formula ΔP1=P 密闭室内 -P 进风口 The first pressure difference ΔP1 between them is greater than 0, ΔP2=P 密闭室内 -P 排风口 The second pressure difference ΔP2 between the two is greater than 0, then the pressure P in the sealed chamber 108 密闭室内 , the air pressure P at the air inlet 104 进风口 , the air pressure P at the exhaust port 106 排风口 The difference between the two is small, thereby making the air pressure at each location of the data center cooling space (such as the air inlet 104, the air outlet 106, and the closed room 108) more uniform. In this way, the entrance and exit doors set in each closed space are easier to open, making it convenient for staff to enter and exit.

[0094] According to actual measurements by the inventors, the air pressure at various locations in the refrigeration space of a data center can be as shown in Table 1 below.

In this way, the operating power of the fan of the air intake system 103 can be stabilized each time, extending the service life of the fan of the air intake system 103. Similarly, the operating power of the fan of the exhaust system 105 can be stabilized each time, extending the service life of the fan of the exhaust system 105.
