Description

Data Center Cooling Equipment Failover System

The present disclosure relates to the management of a data center, and more specifically, to a cooling facility control system capable of responding to problems arising in the control of cooling facilities in a data center.

A data center is a physical facility for storing and managing digital data and hosting IT infrastructure. It includes the computing infrastructure required for IT systems, such as servers, data storage drives, and networking equipment. Data centers have evolved from privately owned and controlled on-premises facilities housing traditional IT infrastructure for a single company's use to remote facilities or networks of facilities owned by cloud service providers that house virtualized IT infrastructure for shared use by multiple companies or customers.

IT equipment located in data centers consumes power and can generate continuous heat. Data centers utilize cooling systems to address this issue. Cooling systems play a critical role in the stable operation of data centers and must be optimized to conserve cooling energy. Data center cooling systems are typically configured to facilitate heat exchange between the hot interior and the cooler exterior of the data center. With the increasing demand for data centers, driven by cloud computing and artificial intelligence, and the advancement of data center performance, the energy consumed and generated by data centers is increasing. This, in turn, is driving the energy consumption of cooling systems to alleviate this heat.

Both data centers and the cooling systems that maintain them consume significant energy, and research is ongoing to reduce energy consumption. However, in the operation of cooling systems, maintaining high availability of the data center is also important, beyond energy conservation.

Therefore, there is a demand for cooling systems that can reduce energy consumption while ensuring high availability of data centers.

Republic of Korea Patent No. 10-1863709 discloses a data center air conditioning system.

The present disclosure is conceived based on the aforementioned background technology and relates to a data center cooling control system for reducing energy consumption while ensuring high availability of the data center.

According to one embodiment of the present disclosure for achieving the above-described task, a control system for controlling cooling of a data center is disclosed. The control system may include a power supply unit for supplying power to the control system; a control unit for receiving a control signal from a control center and generating an operation control signal for controlling each of one or more cooling elements; a transistor that is activated based on the operation control signal and generates driving power for driving a switching unit; and a switching unit including a latching relay that controls a switching unit for each cooling element according to the driving power by the transistor, and maintains a state of the switching unit in a predetermined state when the driving power is cut off.

Alternatively, the power supply unit may include an uninterruptible power supply (UPS).

Alternatively, the cooling element controlled by the above motion control signal may include one or more chillers, one or more pumps, and one or more valves.

Alternatively, the transistor may include a phototransistor that is activated by light according to the operation control signal.

Alternatively, the transistor may include a first transistor for generating driving power to cause the contacts of the switching unit to come into contact and a second transistor for generating driving power to cause the contacts of the switching unit to not come into contact.

Alternatively, the transistor may include a plurality of transistors to switch the direction of the electromagnetic force applied to the coil of the switch section.

Alternatively, the switch unit may include a switching toggle knock that causes the switching unit to be switched and fixed in a closed circuit state or an open circuit state of the contact when the switching unit moves according to the driving power of the transistor.

Alternatively, the switching unit may control the operation of each cooling element by operating the contacts in a closed or open circuit state by an electromagnetic force applied by the coil.

Alternatively, the coil may include a first coil that generates an electromotive force to make the contacts of the switching unit into a closed circuit state when the driving power is applied, and a second coil that generates an electromagnetic force to make the contacts of the switching unit into an open circuit state when the driving power is applied.

Alternatively, the latching relay may further include a manual operation unit for changing the state of the switching unit by user operation.

Alternatively, the relay power supply may further include a switching mode power supply for supplying power for operation of the transistor.

The description of the disclosed embodiments is provided to enable a person skilled in the art to make or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein may be applied to other embodiments without departing from the scope of the present disclosure. Therefore, the present invention is not limited to the embodiments disclosed herein. The present invention is to be construed in the widest scope consistent with the principles and novel features disclosed herein.

FIG. 1 is a block diagram of a data center cooling control system according to one embodiment of the present disclosure.

A data center cooling control system may include cooling elements (10) for cooling a data center. The cooling elements (10) may include equipment necessary to cool the interior of the data center and maintain the temperature of the data center at an appropriate level. The cooling elements (10) may include one or more chillers (11), pumps (12), and valves (13). Each cooling element may be configured for a different cooling scenario depending on the configuration, structure, heat generation, etc. of the data center. The chiller (11) is a facility that removes heat from a coolant. The coolant is circulated by a pump (12) to remove heat from the data center. The coolant heated by heat generated in the data center may be moved by the pump (12) and the heat may be removed again from the chiller (11). The valve (13) may control the movement of the coolant flowing in the chiller (11) and the pump (12). When the valve (13) is opened, the coolant can be moved, and when the valve (13) is closed, the movement of the coolant can be stopped. By using cooling elements such as a chiller (11), a pump (12), and a valve (13), the coolant with heat removed can be moved by the pump to the parts of the data center that require cooling, and the movement of the coolant can be stopped to the parts that do not require cooling, thereby saving the energy required for heat exchange of the coolant.

Each of the aforementioned cooling elements (10) can be controlled by a control system (100). The control system (100) can receive control signals from a control center (200) and control the cooling elements. The control center (200) can control cooling of the data center based on information about the status of the data center. The control center (200) can be a separate entity from the control system (100). The control center (200) can perform status control for one or more data centers. The control system (100) can correspond one-to-one with the data centers, or can correspond one-to-N or N-to-N. The control center (200) can generate a control signal according to a cooling scenario based on the status of the data center (e.g., load status, external environmental status, etc.), or can be manually generated by an operator.

The control signal transmitted from the control center (200) may be a control signal for each cooling element. In this case, the operation control signal of the control system (100) may be a signal for hardware-driven control signals received from the control center (200). For example, the control signal transmitted from the control center (200) may be a control signal that directly controls the operation of each cooling element according to a cooling scenario. In addition, the control signal transmitted from the control center (200) may be a command for a cooling scenario of the data center, and the control system (100) may appropriately control each cooling element according to the control signal. In this case, the operation control signal may be generated according to a rule predetermined in the control unit of the control system (100). For example, if the control signal is a signal to stop the operation of a specific chiller, the control system (100) may receive the control signal and turn off a switch connected to the chiller corresponding to the control signal. Also, in another example, the control signal may be a signal regarding the temperature setting of the data center, in which case the control system (100) may receive the control signal and turn off the switch connected to the chiller to stop the operation of the chiller in accordance with the cooling scenario set by the control center. In the above description, the operation of each cooling element (10) may be controlled by the operation control of the control system (100), and the degree of each operation may be determined in a predetermined manner for each cooling element. For example, the control system (100) may only determine whether the chiller is operated on, and the temperature at which the chiller will operate may be separately determined according to the cooling scenario of the chiller. The above-described operation is merely an example, and the present disclosure is not limited thereto.

Below, embodiments of the control system (100) will be described in detail with reference to the drawings.

FIG. 2a and FIG. 2b are circuit diagrams showing the switching unit control of a control system for cooling control of a data center according to one embodiment of the present disclosure.

The control system (100) for cooling control of a data center can receive a control signal from the control center (200) as described above and control the operation of each cooling element (10) for cooling the data center.

The control system (100) may include a power supply unit (110) for supplying power to the control system. The power supply unit (110) may supply power for the control unit (120) and other elements of the control system to operate. For control stability, the power supply unit (110) may include an uninterruptible power supply (UPS). In addition, the power supply unit (110) may include a power status monitoring unit (not shown) for detecting a problem in the power supply and notifying the control center (200).

The control unit (120) may receive a control signal from the control center (200) and generate an operation control signal for controlling each of one or more cooling elements. As described above, the operation control signal may be a signal corresponding to a control signal in a scenario in which the control center (200) determines the operation of each cooling element, and may also be a signal generated by the control unit (120) to control each cooling element for the cooling scenario of the control center (200). The control unit (120) may be configured as a processing device capable of generating an operation control signal for controlling the operation of an actual circuit according to the control signal. The control unit (120) may be configured as, for example, a central processing unit (CPU) of a computer.

The control unit (120) may receive a control signal from the control center and generate an operation control signal for controlling each of one or more cooling elements (10). The operation control signal may include a signal for driving a transistor to be described later. The operation control signal may be a signal for each of one or more cooling elements, and each of one or more cooling elements may be driven by a corresponding switch unit (140), and the control unit (120) may generate an operation control signal to control each of the switch units (140).

The transistor (130) can be activated based on an operation control signal to generate driving power for driving the switch unit. The coil (141) of the switch unit (140) can generate an electromagnetic force by the driving power of the transistor (130), and the switching unit (142) can move by the electromagnetic force generated by the coil (141) so that the contact (145) can be in an open circuit or closed circuit state. The transistor (130) can be a phototransistor that is activated by light activated according to the operation control signal. The control system (100) can include a light-emitting unit (131) that emits light for activating the transistor (130). The light-emitting unit (131) can activate the transistor by emitting light based on the operation control signal of the control unit (120). The description of the transistor (130) is merely an example, and the transistor of the present disclosure is not limited to a phototransistor.

The control system (100) may include one or more transistors to control the position of a contact by a switching unit (142). The examples of FIGS. 2A and 2B illustrate an embodiment in which one transistor (130) is provided to control one switching unit (140).

When the transistor (130) is activated and driving power is generated, the coil (141) can apply an electromagnetic force to the switching unit (142) according to the driving power, and the switching unit (142) can be moved by the electromagnetic force of the coil (141) to switch the contact (145) on/off.

The transistor (130) can receive power from the relay power supply (150) and supply driving power to the coil (141). The relay power supply (110) can include a switching mode power supply for supplying power for the operation of the transistor.

The switch unit (140) of the present disclosure may include a latching relay in which a switching unit for each cooling element is controlled according to the driving power by the transistor (130), and the state of the switching unit is maintained in a predetermined state when the driving power is cut off. The switch unit (140) may open and close a circuit according to the power applied to the switch unit (140) in a relay manner.

The switch unit (140) is configured as a latching relay and can switch the circuit to an open circuit or closed circuit state depending on the power, and even if the power applied to the switch unit (140) is not maintained after the state of the circuit is switched, the final state of the circuit can be maintained. For example, if the switch unit (140) is configured as a power relay, power may be consumed to maintain the switching state of the switch unit. However, the switch unit (140) of the present invention is configured as a latching relay and thus does not require power consumption to maintain operation, thereby reducing power consumption by the control system.

In addition, the control system (100) of the present disclosure is intended to control the cooling of a data center, and can maintain a switching state even when a failure occurs in the control system (100) for some reason (e.g., power cut to the control unit, control unit failure, power cut to the transistor, etc.). For example, when a chiller is turned on and cooling is in operation for a data center, even if a failure occurs in the control system (100), the chiller remains on, thereby minimizing damage to the data center that may occur until recovery. In various cooling scenarios for a data center, maintaining the availability of the data center itself may be treated as more important than controlling the cooling system energy-efficiently. The control system of one embodiment of the present disclosure has the advantage of being able to mechanically maintain the current cooling state even when a failure occurs, thereby maintaining the availability of the data center during recovery from the failure. For example, if a control system malfunction occurs and the control circuit for the cooling elements becomes an open circuit, the cooling elements may not operate and serious damage may occur to the data center. However, according to the control system of one embodiment of the present disclosure, even if a control system malfunction occurs, the cooling control state prior to the malfunction is maintained, thereby preventing damage that may occur to the data center.

In one embodiment of the present disclosure, the latching relay of the switch unit (140) may further include a manual operation unit for changing the state of the switching unit by user operation. In addition, each switch unit (140) may additionally include an indicator for controlling the on/off state of the switch unit (140) according to the cooling scenario when a failure of the control system (100) occurs. As described above, the switch unit (140) of the present invention can prevent damage to the data center by maintaining the last operating state when a failure of the control system (100) occurs. In order to prevent damage to the data center while also ensuring a quick recovery and efficient data center cooling control, each switch unit (140) that requires on/off switching for each cooling scenario may be additionally equipped with an indicator for the operating state for each cooling scenario. For example, in the case of a switch unit that requires switching depending on the external environment or the duration of the failure, an indicator including switching information according to the scenario may be included so that an administrator can easily manually switch the state. For a more specific example, in an environment where the outside temperature is 30 degrees, the outage time exceeds 5 hours and sunrise is expected, additional operation of the chiller may be required. In this scenario, the switch corresponding to the chiller requiring additional operation may include an indicator indicating that it should be turned on in that situation. That is, the above-mentioned indicator may be provided so that each switch unit can be visually distinguished by color, etc. based on the external environment, the load of the data center, the duration of the outage, etc. For example, in a case where additional cooling demand is expected due to an increase in the outside temperature or an increase in the load of the data center, a switch that should be turned on may be provided with a red indicator, etc., so that an operator can easily recognize the switch that needs to be turned on. In addition, the indicator of one embodiment of the present disclosure may be implemented as a display that does not require a power supply for display, such as an electronic ink display. In addition, the indicator of one embodiment of the present disclosure may be implemented as a light provided to each switch unit, and the light provided to each switch unit may express one or more colors and may be operated through power control separate from the control system. When indicators are implemented as variable lighting, the visual indications displayed on each indicator can change depending on the control system's fault status and progress. For example, if a switch that should be on at the beginning of a fault needs to be switched off as the fault progresses, the indicator can be controlled based on the fault duration to display a visual indication to the operator to turn off the switch.

As described above, each switch unit can correspond to each cooling element, and the mapping relationship between each switch unit and the cooling element can be displayed in the space where the switch unit is located, stored in the control system (100), or exist in a form that can be confirmed through a terminal carried by an operator.

In the example of Fig. 2a, when the light emitting unit (131) is driven by the control unit (120), the transistor (130) is activated to supply power to the coil (141), and the switching unit (142) is driven by the electromagnetic force of the coil (141) so that the contact (145) can be brought into contact. The spring (143) can apply force to the switching unit (142) depending on the position of the switching unit (142). The spring (143) can apply force so that the switching unit (142) is in an open circuit position or can apply force so that it is in a closed circuit position. The direction of the elastic force of the spring (143) can be changed according to the design needs.

The switching toggle knock (144) can be configured to cause the position of the switching unit (142) to be switched and fixed to the closed circuit state or the open circuit state of the contact (145) when an electromagnetic force is applied to the switching unit (142). The switching toggle knock (144) can cause the final position of the switching unit (142) to be changed whenever the switching toggle knock (144) is pressed by the electromagnetic force applied to the switching unit (142). That is, when an electromagnetic force is applied to the switching unit (142) in the open circuit state, the gear inside the switching toggle knock (144) can be switched and maintained in a contracted state so that the switching toggle knock (144) is pressed and the switching unit (142) is positioned in the closed circuit state. When an electromagnetic force is applied to the switching unit (142) in a closed circuit state, the switching toggle knock (144) is pressurized, and the gear inside the switching toggle knock (144) is switched so that the switching unit (142) is positioned in an open circuit state and can be maintained in an expanded state. The switching toggle knock (144) is driven by two or more gears whose positions are switched according to the pressurization, and the meshing state of the internal gears is switched according to the pressurization so that the switching toggle knock (144) can be maintained in a contracted or relaxed state. Accordingly, when each switching unit (140) applies an electromagnetic force to the switching unit (142) by one coil (141), the state of the contact can be switched and maintained in an open circuit or closed circuit state. FIG. 2b is a diagram illustrating that the coil (141) is activated by the driving power from the transistor (130), thereby applying an electromagnetic force to the switching unit (142), and the switching toggle knock (144) pressed by the switching unit (142) is switched to a relaxed state, thereby switching the contact (145) to an open circuit. For an example of the internal gear of the switching toggle knock (144), refer to Korean Patent No. 10-2399598, the entire contents of which are incorporated herein by reference.

FIGS. 3A and 3B are circuit diagrams showing switching unit control of a data center cooling control system according to another embodiment of the present disclosure.

Figures 3a and 3b are drawings showing an embodiment in which the switch unit (140) has contacts controlled by electromagnetic force from two coils. In the description of Figures 3a and 3b, descriptions of components overlapping with those of Figures 2a and 2b are as described above.

In another embodiment of the present disclosure, the transistor (130) may include a first transistor (1301) for generating driving power to cause the contact (145) to come into contact and a second transistor (1302) for generating driving power to cause the contact (145) not to come into contact.

In addition, the control system (100) may include light emitting units (1311, 1312) corresponding to each transistor to activate each transistor. As in the example of FIG. 3A, the first light emitting unit (1311) may activate the first transistor (1301) and, when the first transistor (1301) is activated, may provide driving power to the first coil (1411). The first coil (1411) may apply an electromagnetic force to the switching unit (142) to close the contact (145). When the movement of the switching unit (142) is completed and the contact (145) closes, the control system (100) may deactivate the first light emitting unit (1311), and the first transistor (1301) may also be deactivated to stop providing driving power to the coil. As described above, the switch unit (140) of one embodiment of the present disclosure can maintain a switching state even when the driving power supply to the coil is interrupted by using a latching relay. The switch unit using the latching relay can maintain the contact point (145) of the switch unit in a closed circuit state without consuming energy to maintain switching in the state, and the switch unit can be unaffected in its operating state even when a failure occurs in the control unit, etc.

When the control unit (120) wants to turn off the switch unit (140), the control unit (120) can activate the second light-emitting unit (1312) as illustrated in FIG. 3B. The second transistor (1312) is activated by the second light-emitting unit (1312), so that driving power can be supplied to the second coil (1412), and the second coil (1412) can apply an electromagnetic force to the switching unit (142) to open the contact (145). When the movement of the switching unit (142) is completed and the contact (145) becomes an open circuit, the control system (100) can deactivate the second light-emitting unit (1312), and the second transistor (1302) can also be deactivated to stop providing driving power to the coil. As described above, the switch unit (140) of one embodiment of the present disclosure can maintain a switching state even when the supply of driving power to the coil is interrupted by using a latching relay.

FIGS. 4A and 4B are circuit diagrams showing switching unit control of a data center cooling control system according to another embodiment of the present disclosure.

FIGS. 4A and 4B are diagrams showing an embodiment in which a switch unit (140) has a contact point controlled by an electromagnetic force from a single coil. In the examples of FIGS. 4A and 4B, the switching state of the switch unit (140) can be switched depending on the direction of the electromagnetic force from the single coil.

For this purpose, the control system (100) may include a plurality of transistors. The control system (100) may include a plurality of transistors so as to be able to change the direction of the electromagnetic force applied to the coil of the switch unit. Although four transistors are shown in the examples of FIGS. 4A and 4B, this is merely an example, and an appropriate number of transistors capable of changing the direction of the electromagnetic force of the coil may be included within the scope of the present invention.

Fig. 4a is an example showing the operation of a transistor in a closed circuit state. In the example of Fig. 4a, the control unit can activate the third transistor (1303) and the sixth transistor (1306) by activating the third light-emitting unit (1313) and the sixth light-emitting unit (1316). The activated third transistor (1303) and the sixth transistor (1306) can provide power to the coil (1413) in a direction that generates an electromagnetic force that moves the switching unit (142) to form a closed circuit.

Fig. 4b is an example showing the operation of the transistor in an open circuit state. In the example of Fig. 4b, the control unit can activate the fourth foot unit (1314) and the fifth light emitting unit (1315) to activate the fourth transistor (1304) and the fifth transistor (1305). The activated fourth transistor (1304) and fifth transistor (1305) can provide power to the coil (1413) in a direction that generates an electromagnetic force that moves the switching unit (142) to form an open circuit. In the exemplary embodiments of Figs. 4a and 4b, the switching unit (142) can have an electromagnetic polarity and can operate to have an attractive or repulsive force with the coil depending on the direction of the electromagnetic force applied by the coil.

As in the operation of other embodiments described above, after the state of the contacts has been switched, all transistors may be deactivated until another control signal is received. As described above, the latching relay maintains the state of the contacts in the same manner as before even in such situations, thereby reducing the power consumed to maintain the contact state, and the control state may not be affected by a failure of the control system (100).
