For the refrigeration scheduling scheme provided for the micro-module data center, each micro-module is integrated with a closed cold aisle and is equipped with corresponding redundant in-row air conditioners.

[0053] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0054] The solution provided by the embodiments of the present invention is applicable to scenarios of container clusters, spliced or stacked data centers, where the air supply and return distances from the refrigeration equipment to the equipment inside each container all meet the requirements. The embodiments of the present invention will mainly be described by taking the scenario of container clusters as an example.

[0055] Figure 1 It is a schematic diagram of a data center provided by an embodiment of the present invention. As Figure 1 Exemplarily shown is a multi-container cluster data center scenario. The data center includes multiple containers, a main channel (shown as the thick line in the middle), a diversion channel, and a direct ventilation valve.

[0056] Among them, each container has corresponding refrigeration equipment. The refrigeration equipment includes common refrigeration equipment and standby refrigeration equipment. Each container is connected to the main channel through a corresponding diversion channel, where the main channel is used for the flow of cold air. A direct ventilation valve is provided between each diversion channel and the main channel to control the connection between containers through the main channel.

[0057] In the data center provided by the embodiments of the present invention, each container has an independent refrigeration system, including common refrigeration equipment and standby refrigeration equipment. The containers are interconnected through a main channel and a shunt channel, and the connection state between the corresponding container and the main channel is controlled by a direct ventilation valve. The data center provided by the embodiments of the present invention can be set up in the form of containers for clustering, splicing or stacking. The location of the data center can be freely set. The containers at a long distance can also achieve cold quantity complementarity through the main channel, ensuring the normal operation of the equipment in the complementary containers while meeting the emergency cooling requirements of the container itself in an abnormal operating state, and realizing the stable operation of the container.

[0058] Figure 1 Exemplarily, the connection between the container and the main channel is shown. In different embodiments, the ways of the shunt channels between each container and the main channel are different.

[0059] In one possible implementation, as Figure 2 shown, a schematic diagram of a data center is shown. Among them, the shunt channel includes a common shunt channel and a standby shunt channel; the direct ventilation valve includes a common direct ventilation valve and a standby direct ventilation valve; the common shunt channel is connected to the common refrigeration equipment; the standby shunt channel is connected to the standby refrigeration equipment; the direct ventilation valve is arranged on the common shunt channel, and the standby direct ventilation valve is arranged on the standby shunt channel.

[0060] Figure 2 In the data center shown, the cold quantity redundancy of the common refrigeration equipment and the standby refrigeration equipment of each container is used as the complementary cold quantity to reduce the adjustment of the operating states of multiple containers and reduce unnecessary losses generated during the cold quantity complementarity process.

[0061] In one possible implementation, the cold quantity redundancy of the standby refrigeration equipment of each container is used as the complementary cold quantity to avoid affecting the stable operation of the containers in the normal operating state during the complementarity process. At this time, the shunt channel is connected to the standby refrigeration equipment in the container.

[0062] In one possible implementation, the cold quantity redundancy of the common refrigeration equipment of each container is used as the complementary cold quantity to avoid frequent startup of the standby refrigeration equipment. At this time, the shunt channel is connected to the common refrigeration equipment in the container. Among them, there is a redundant design for the maximum cold quantity output of the common refrigeration equipment, that is, the maximum cold quantity output of the common refrigeration equipment is greater than the maximum cold quantity demand during the normal operation of the container.

[0063] In a possible implementation, the shunt channel is connected to the cold channel in the container. The foregoing embodiment provides that the shunt channel is connected to the refrigeration device, and this connection method will reduce the discharge effect when the faulty container uses the cold quantity in other containers as complementary cold quantity. Therefore, directly connecting the shunt channel to the cold channel in the container can reduce the pressure of cold quantity circulation, improve the utilization rate of cold quantity, and thus improve the adjustment rate of the container temperature.

[0064] In a possible implementation, the data center further includes: a partition valve disposed on the main channel for dividing the communication range of the main channel. For example, when it is determined that Figure 2 the cold quantity complementarity is carried out among the containers 1, 2, and 4 shown in the figure, the partition valves of the containers 2 and 5 on the main channel are controlled to define the main channel between the containers 1, 2, and 4 as the current cold quantity circulation range. By dividing the main channel through the partition valve, the dispersion range of the cold quantity in the main channel can be reduced, the energy loss can be reduced, and the energy consumption can be saved.

[0065] Optionally, the installation position of the partition valve is determined based on the distribution density of the containers or the rated power of the equipment in the containers.

[0066] Figure 3 is a schematic diagram of the data center provided by an embodiment of the present invention. As Figure 3 shown, a bypass channel and a bypass valve are further provided between the container 1 and the container 2.

[0067] Among them, the bypass channel is arranged between two containers with a distance less than the set distance for directly connecting the two containers. The bypass air valve is arranged on the bypass channel to control the communication between adjacent two containers through the bypass channel. The bypass air valve usually remains closed and can ensure good air flow isolation between the boxes. When the bypass air valve is opened, it can control the air flow interaction between the boxes through the channel.

[0068] In this embodiment, the bypass valve is provided to realize the cold quantity complementarity between the containers at close range, shorten the connection channel distance between adjacent containers, reduce the loss of cold quantity in the channel, and save energy consumption.

[0069] During the refrigeration process of the refrigeration device, tail gas will be generated or heat dissipation is required. In different embodiments, the heat dissipation methods of the container refrigeration device are different.

[0070] In a possible implementation, the refrigeration device directly discharges the heat into the external environment of the container.

[0071] In a possible implementation, when containers are centrally arranged, heat needs to be discharged centrally. Then, the data center further includes: a secondary channel and a manifold channel. The manifold channel is used to connect the hot channel in the container to the secondary channel. Each container is connected to the secondary channel through a corresponding manifold channel. The secondary channel centrally discharges the hot air in the hot channel of the container, realizing heat dissipation during the refrigeration process of the refrigeration equipment.

[0072] In a specific embodiment, devices such as a fan are provided in the secondary channel to provide power for discharging the air in the hot channel of the container, so as to accelerate the flow of cold air and hot air in the container and improve the refrigeration efficiency.

[0073] In a possible implementation, the diversion channel is connected to the lower half or the bottom of the container. The manifold channel is connected to the upper half or the top of the container.

[0074] Due to the principle that hot air rises and cold air descends, the hot air in the container will be centrally distributed in the upper part of the container, while the cold air will be centrally distributed in the lower part of the container. Therefore, connecting the diversion channel to the lower half or the bottom of the container and connecting the manifold channel to the upper half or the top of the container facilitates the discharge of hot air to the secondary channel through the manifold channel, and as the hot air is discharged, it is convenient for the cold air to rise from the bottom of the container, realizing rapid cooling.

[0075] To make the objectives, technical solutions and advantages of the present invention clearer, the following will be described through specific embodiments with reference to the accompanying drawings.

[0076] Figure 4 The flowchart of the refrigeration control method for a data center provided by an embodiment of the present invention is shown as follows. As shown in the figure, the method includes the following steps:

[0077] S401, detecting the operating states of the container and the corresponding common refrigeration equipment.

[0078] Among them, the refrigeration control center centrally detects the operating states of multiple containers and the corresponding common refrigeration equipment to realize centralized management of each container. When the operating state of the container or the common refrigeration equipment is abnormal, the rate of determining the refrigeration adjustment strategy is improved, and the stable operation of each container is controlled.

[0079] In a possible implementation, detecting the operating state of the container includes detecting the temperature inside the container. When the temperature inside the container is greater than the temperature threshold, it is determined that the operating state of the container is abnormal.

[0080] In a possible implementation, the common refrigeration equipment in the container is an air conditioner or a water-cooled device.

[0081] Optionally, when a common refrigeration device fails, it sends a fault message to the refrigeration control center. When the refrigeration control center detects the fault message sent by the common refrigeration device and it is a fault message of a component related to refrigeration, it determines that the operating state of the common refrigeration device is abnormal.

[0082] Optionally, the refrigeration control center detects the states of the components related to refrigeration in the common refrigeration device. For example, when the common refrigeration device is an air conditioner and the refrigeration control center detects abnormalities in components such as the compressor, condenser, evaporator, four-way valve, or one-way valve capillary in the common refrigeration device, it determines that the operating state of the common refrigeration device is abnormal.

[0083] S402, when it is detected that the operating state of the container and / or the common refrigeration device is abnormal, and the standby refrigeration device corresponding to the container is abnormal or the refrigeration capacity does not meet the cold quantity requirement of the container, it is determined that the containers connected through the main channel are complementary containers.

[0084] In different embodiments, when the operating state of the container or the common refrigeration device is abnormal, or the operating states of both are abnormal, the temperature inside the container is higher than the temperature threshold, and the equipment inside the container cannot operate stably, and it is necessary to reduce the temperature inside the container. When the data center is established, in order to ensure the efficient and safe operation of the cabinets, redundant settings are made for each independent refrigeration device.

[0085] In the embodiments of the present invention, when the operating state of the container or the common refrigeration device is abnormal, first determine whether the refrigeration capacity of its own redundant setting can maintain the stable operation of the equipment inside the container. When the standby refrigeration device of the container itself is abnormal or the refrigeration capacity of the standby refrigeration device does not meet the cold quantity requirement of the container, the cold quantity redundancy of the adjacent container is preferentially used as its own standby cold quantity.

[0086] In the embodiments of the present invention, it is determined that the containers connected through the main channel are complementary containers, and the complementary containers are determined in the order from near to far according to the distance, and the state of itself is adjusted with the redundancy of the complementary containers. This determination method of the complementary containers simplifies the adjustment process and improves the adjustment rate of the container state.

[0087] In a possible implementation manner, the method further includes: when it is detected that the operating state of the container and / or the common refrigeration device is abnormal, and the standby refrigeration device corresponding to the container is normal, turn on the standby refrigeration device corresponding to the container. That is, when the operating state of the container or the common refrigeration device is abnormal, first detect the standby refrigeration device of the container itself, and when the standby refrigeration device is normal, determine that there is cold quantity redundancy in itself. At this time, turn on the refrigeration device of the container itself to adjust the ambient temperature to ensure the stable operation of the equipment inside the container without affecting the operation of other containers.

[0088] In a possible implementation, after starting the standby refrigeration equipment corresponding to the container, it further includes:

[0089] Detecting the operating state of the container and / or the common refrigeration equipment again after a set time;

[0090] When the operating state of the container and / or the common refrigeration equipment is abnormal, determining the containers connected through the main channel as complementary containers and performing subsequent operations.

[0091] S403, determining an adjustment strategy based on the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container, and controlling the state of the refrigeration equipment and the direct ventilation valve in one or more complementary containers according to the adjustment strategy, and / or controlling the state of the refrigeration equipment and the bypass ventilation valve in adjacent complementary containers.

[0092] Among them, the adjustment strategy is preferably determined based on adjacent complementary containers to accelerate the state adjustment of the faulty container. That is, when determining the adjustment strategy, the state of the refrigeration equipment and the bypass ventilation valve in adjacent complementary containers is preferably determined first. Secondly, comprehensively control the state of the refrigeration equipment and the direct ventilation valve in one or more complementary containers, and control the state of the refrigeration equipment and the bypass ventilation valve in adjacent complementary containers. Finally, when there is no bypass ventilation valve and bypass channel between adjacent complementary containers, or when adjacent complementary containers fail, consider controlling the state of the refrigeration equipment and the direct ventilation valve in one or more complementary containers when determining the adjustment strategy.

[0093] In a possible implementation, after controlling the state of the refrigeration equipment and the bypass ventilation valve in adjacent complementary containers, it further includes controlling the state of the direct ventilation valve in adjacent complementary containers to accelerate the complementary process of the cooling capacity.

[0094] In the embodiments of the present invention, by detecting the operating state of the container and the corresponding common refrigeration equipment, and when it is detected that the operating state of the container and / or the common refrigeration equipment is abnormal, and the standby refrigeration equipment corresponding to the container is abnormal or the cooling capacity does not meet the cooling demand of the container, determining the containers connected through the main channel as complementary containers. That is, when the container has a refrigeration failure and is in an abnormal operating state, the cooling capacity of the complementary container is used as the standby cooling capacity. Determine the adjustment strategy based on the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container, and control the state of the refrigeration equipment and the direct ventilation valve in one or more complementary containers according to the adjustment strategy, ensuring the normal operation of the equipment in the complementary container while meeting the emergency cooling demand of the container itself in the abnormal operating state, and realizing the stable operation of the container.

[0095] Among them, in step S403, since the refrigeration equipment in the container includes common refrigeration equipment and standby refrigeration equipment, during the normal operation of the complementary container, when the cooling capacity output of the common refrigeration equipment is not the maximum output, there is also cooling capacity redundancy in the common refrigeration equipment. Therefore, the cooling capacity redundancy includes two parts, namely the cooling capacity redundancy of the common refrigeration equipment and the cooling capacity redundancy of the standby refrigeration equipment. In different embodiments, different adjustment strategies are determined according to the different orders of preferentially using the cooling capacity redundancy of the common refrigeration equipment or the standby refrigeration equipment in the complementary container, and the corresponding processes of determining the adjustment strategies are different.

[0096] Optionally, the adjustment strategy includes: the opening quantity of the direct ventilation valve and the opening quantity of the standby refrigeration equipment in the complementary container; or, the opening quantity of the side ventilation valve and the opening quantity of the standby refrigeration equipment in the adjacent complementary container; or, the opening quantity of the direct ventilation valve, the opening quantity of the side ventilation valve and the opening quantity of the standby refrigeration equipment in the complementary container;

[0097] Among them, each container includes one or more standby refrigeration equipment; the opening quantity of the standby refrigeration equipment in the complementary container is greater than or equal to the opening quantity of the direct ventilation valve and the opening quantity of the side ventilation valve.

[0098] In a possible implementation manner, the cooling capacity redundancy of the standby refrigeration equipment is used as the cooling capacity complementary quantity. The adjustment strategy includes: the opening quantity of the standby refrigeration equipment and the opening quantity of the direct ventilation valve in the complementary container. Among them, each container includes one or more standby refrigeration equipment; the opening quantity of the standby refrigeration equipment in the complementary container is greater than or equal to the opening quantity of the direct ventilation valve. When determining the adjustment strategy, the cooling capacity redundancy of the standby refrigeration equipment in the complementary container is preferentially used as the backup cooling capacity, that is, the standby refrigeration equipment in the complementary container is turned on without changing the state of the common refrigeration equipment in the complementary container, and the standby refrigeration equipment in the complementary container can be turned off after the container state is restored, which simplifies the control process and reduces the impact on the operation stability of the complementary container.

[0099] Optionally, each container has an independently used standby refrigeration equipment. When it is determined that multiple standby refrigeration equipment need to be turned on according to the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container, the opening quantity of the standby refrigeration equipment is equal to the opening quantity of the direct ventilation valve and greater than 1.

[0100] Optionally, each container has multiple independently used standby refrigeration equipment. When it is determined that multiple standby refrigeration equipment need to be turned on according to the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container, if the number of standby refrigeration equipment to be turned on is less than or equal to the number of independently used standby refrigeration equipment in each container, the opening quantity of the standby refrigeration equipment is greater than the opening quantity of the direct ventilation valve.

[0101] Correspondingly, in a possible implementation, a regulation strategy is determined according to the cold quantity shortage of the container and the cold quantity redundancy of the complementary container, including:

[0102] Determining the number of activated standby refrigeration devices according to the cold quantity shortage and the refrigerating capacity of each standby refrigeration device;

[0103] Determining the number of activated direct ventilation valves according to the determined number of activated standby refrigeration devices and the number of standby refrigeration devices in each container.

[0104] Optionally, the refrigerating capacity of each standby refrigeration device is the same, and the number of standby refrigeration devices in each container is the same. When the operating state of a certain container is abnormal, the rate of determining the number of activated standby refrigeration devices and adjusting the state of one or more containers can be increased, so that the operating state of the container can be quickly restored and stably operated.

[0105] Optionally, the number of standby refrigeration devices in each container is the same, but the refrigerating capacity of the standby refrigeration devices in different containers is set according to the different functions of the devices in the containers. At this time, when determining the number of activated standby refrigeration devices according to the cold quantity shortage and the refrigerating capacity of each standby refrigeration device, the complementary containers are calculated one by one in the order from near to far.

[0106] In a possible implementation, the cold quantity redundancy of the common refrigeration device is used as the cold quantity complementary amount. Then the regulation strategy includes: the number of activated direct ventilation valves and the regulation strategy for the state of the common refrigeration device in the complementary container.

[0107] In a possible implementation, the cold quantity redundancy of the common refrigeration device and the standby refrigeration device is used as the cold quantity complementary amount. Then the regulation strategy includes: the number of activated common direct ventilation valves, the number of activated standby direct ventilation valves, the number of activated standby refrigeration devices in the complementary container, and the regulation strategy for the state of the common refrigeration device in the complementary container.

[0108] Correspondingly, in a possible implementation, the cold quantity redundancy corresponding to each complementary container includes a first redundancy of the common refrigeration device and a second redundancy of the standby refrigeration device;

[0109] Determining a regulation strategy according to the cold quantity shortage of the container and the cold quantity redundancy of the complementary container, including:

[0110] Determining the number of activated direct ventilation valves according to the cold quantity shortage and the cold quantity redundancy of one complementary container, or determining the number of activated direct ventilation valves according to the cold quantity shortage and the total cold quantity redundancy of multiple complementary containers; wherein, multiple complementary containers are determined in the order from near to far according to the distance from the container with abnormal operating state.

[0111] In a possible implementation, determining an adjustment strategy based on the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container further includes:

[0112] When the number of opened direct ventilation valves is one, if the first redundancy of the complementary container is greater than the cooling capacity shortage of the container, determine the state adjustment strategy of the common refrigeration equipment according to the difference between the cooling capacity shortage and the first redundancy, so as to increase the refrigeration power of the common refrigeration equipment; otherwise, adjust the common refrigeration equipment to work with the maximum cooling capacity output, and determine the number of opened standby refrigeration equipment in the complementary container according to the difference between the cooling capacity shortage and the first redundancy, and the second redundancy of the standby refrigeration equipment.

[0113] In a possible implementation, when the cooling capacity redundancy of a complementary container is less than the cooling capacity shortage of the container with abnormal operating state, determining an adjustment strategy based on the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container further includes:

[0114] When the number of opened direct ventilation valves is multiple, determine the complementary container with the farthest distance from the container with abnormal operating state among the multiple complementary containers as the first complementary container, and determine the containers other than the first complementary container among the multiple complementary containers as the second containers;

For the sake of convenience of description, only the parts related to the embodiments of the present invention are shown and are described in detail as follows:

[0121] As Figure 5 shown, the apparatus 5 for data center refrigeration control includes: a detection module 501, a determination module 502, and a control module 503.

[0122] The detection module 501 is used to detect the operating states of the container and the corresponding common refrigeration equipment.

[0123] The determination module 502 is used to determine, when it is detected that the operating states of the container and / or the common refrigeration equipment are abnormal and the standby refrigeration equipment corresponding to the container is abnormal or the refrigeration capacity does not meet the cold quantity requirement of the container, that the containers connected through the main channel are complementary containers, and determine an adjustment strategy according to the cold quantity shortage of the container and the cold quantity redundancy of the complementary containers.

[0124] The control module 503 is used to control the states of the refrigeration equipment and the direct ventilation valves in one or more complementary containers according to the adjustment strategy, and / or control the states of the refrigeration equipment and the bypass ventilation valves in adjacent complementary containers.

[0125] In a possible implementation manner, the control module 503 is further used to turn on the standby refrigeration equipment corresponding to the container when it is detected that the operating states of the container and / or the common refrigeration equipment are abnormal and the standby refrigeration equipment corresponding to the container is normal.

[0126] In a possible implementation manner, the detection module 501 is further used to detect the operating states of the container and / or the common refrigeration equipment again after the standby refrigeration equipment corresponding to the container is turned on for a set time;

[0127] The determination module is further used to, when the operating states of the container and / or the common refrigeration equipment are abnormal, perform the operations of determining that the containers connected through the main channel are complementary containers and subsequent operations.

[0128] In the embodiments of the present invention, by detecting the operating states of a container and the corresponding common refrigeration equipment, and when it is detected that the operating states of the container and / or the common refrigeration equipment are abnormal, and the corresponding standby refrigeration equipment of the container is abnormal or the refrigeration capacity does not meet the cooling requirement of the container, it is determined that the containers connected through the main channel are complementary containers. That is, when the container has a refrigeration failure and is in an abnormal operating state, the cooling capacity of the complementary container is used as the standby cooling capacity. An adjustment strategy is determined according to the cooling capacity shortage of the container and the cooling capacity redundancy of the complementary container, and the states of the refrigeration equipment and the direct ventilation valves in one or more complementary containers are controlled according to the adjustment strategy, so as to ensure the normal operation of the equipment in the complementary container while meeting the emergency cooling requirement of the container itself in the abnormal operating state, and realize the stable operation of the container.
