A data device: the devices in the data center for storing and processing data may also be referred to as Information Technology (IT) devices.

For ease of understanding, the application scenarios in the present application are briefly described below.

A data center is a complex set of facilities that include not only computer systems and other associated equipment (e.g., communication and storage systems), but also redundant data communication connections, environmental control equipment, monitoring equipment, and various security devices. The micro-module data center can be called as a modular data center, is a new generation data center deployment form based on cloud computing, adopts a modular design concept in order to cope with the development trend of servers such as cloud computing, virtualization, centralization and densification, reduces the coupling of infrastructure to the machine room environment to the maximum extent, integrates subsystems such as power supply and distribution, refrigeration, cabinet, airflow containment, comprehensive wiring and dynamic ring monitoring, improves the overall operation efficiency of the data center, and realizes rapid deployment, elastic expansion and green energy conservation. The data center in this embodiment may be a micro-module data center, or may be a data center in other forms, and the specific application is not limited thereto.

The data center design specification (GB50174) stipulates that air conditioning equipment powered by an uninterruptible power supply system in a data center mainly includes a control system, a tail end chilled water pump, an air conditioner tail end fan, and the like, and these equipment units should share a group of uninterruptible power supply systems with electronic information equipment. Based on the above specification, the present application provides a data center, as shown in fig. 1, the data center 100 including: the system comprises a data device 101, an air conditioning device 102 and an uninterruptible power supply system 103, wherein the uninterruptible power supply system 103 comprises a first power supply module 1031 and a second power supply module 1032.

The first power supply module 1031 is connected in parallel with the second power supply module 1032 through the first switch 1041;

the mains supply is connected to the first power supply module 1031 and the second power supply module 1032, respectively;

the air conditioner 102 is connected to the commercial power through the second switch 1042 and connected to the second power supply module 1032 through the third switch 1043;

the data device 101 is connected to the first power supply module 1031;

based on the data center shown in fig. 1, when the commercial power is interrupted, the first switch 1041 and the second switch 1042 are in an off state, and the third switch 1043 is in a closed state, as shown in fig. 2A, at this time, the commercial power does not output current, the first power supply module 1031 directly outputs the alternating current to the data equipment 101 to provide corresponding electric energy to the data equipment, so that the data equipment 101 may normally operate, and the second power supply module 1032 directly outputs the alternating current to the air conditioning equipment 102 to provide corresponding electric energy to the air conditioning equipment 102, so that the air conditioning equipment 102 may normally operate.

When the commercial power is normal, the second switch 1042 is in a closed state, and the third switch 1043 is in an open state, as shown in fig. 2B, at this time, a part of the alternating current output by the commercial power flows to the air conditioning equipment 102, so as to provide corresponding electric energy for the air conditioning equipment 102, so that the air conditioning equipment 102 normally operates; the other part of the current flows to the first power supply module 1031, the first power supply module 1031 processes the alternating current input by the mains supply and outputs the processed alternating current to the data device 101, so as to provide corresponding electric energy for the data device 101, and the data device 101 can normally work.

As an optional manner, when the utility power is normal, the first switch 1041 is in a closed state, and at this time, the first power supply module 1031 is connected in parallel with the second power supply module 1032, and the second power supply module 1032 serves as a redundant module for supplying power to the data device 101, that is, when the first power supply module 1031 works normally, the second power supply module 1032 is in a dormant state, and the first power supply module 1031 supplies power to the data device 101, so that the data device 101 works normally, and when the first power supply module 1031 is abnormal and the output current cannot make the data device 101 work normally, part or all of the units in the second power supply module 1032 are in a working state, and the unit in the wake-up state in the second power supply module 1032 supplies power to the data device 101, so as to maintain the data device 101 to work normally.

It should be further noted that, in this embodiment, the first power supply module 1031 is to provide the data device 101 with power capable of maintaining normal operation of the data device 101, so the output power of the first power supply module 1031 needs to be greater than or equal to the power consumption of the data device 101. The second power supply module 1032 supplies the air conditioner 102 with electric energy capable of maintaining the normal operation of the air conditioner 102, so the output power of the second power supply module 1032 needs to be greater than or equal to the power consumption of the air conditioner 102.

As an optional manner, in this embodiment, the first power supply module 1031 may include N first conversion units connected in parallel, and the second power supply module 1031 may include M second conversion units connected in parallel, where output power corresponding to each first conversion unit is equal, output power corresponding to each second conversion unit is equal, output power corresponding to each first conversion unit is equal to output power corresponding to each second conversion unit, N is an integer greater than or equal to 1, and M is an integer greater than or equal to 1.

When the N first conversion units all work normally, the commercial power outputs voltage normally, the N first conversion units perform voltage stabilization processing on the voltage input by the commercial power respectively, and input stable voltage to the data device 101 after processing, at this time, the sum of the powers output by the N first conversion units is greater than or equal to the power consumption of the data device 101, that is, the powers output by the N first conversion units can maintain the normal work of the data device 101. In this case, the M second conversion units do not need to have power output as redundant units for supplying power to the data device 101, and the M second conversion units are in the sleep state.

When L first conversion units in the N first conversion units are abnormal, the mains supply normally outputs voltage, the abnormal L first conversion units cannot input voltage to the data equipment 101, the rest N-L first conversion units which normally work respectively perform voltage stabilization processing on the voltage input by the mains supply, and stable voltage is input to the data equipment 101 after processing, at the moment, the sum of the power output by the N-L first conversion units is smaller than the power consumption of the data equipment 101, namely, the power output by the N-L first conversion units is not enough to maintain the normal work of the data equipment 101, under the condition, the N-L first conversion units are used as redundant units for supplying power to the data equipment 101, L second conversion units in the M second conversion units are in a working state to replace the abnormal L first conversion units to perform voltage stabilization processing on the voltage input by the mains supply, after the processing, a stable voltage is input to the data device 101, and at this time, the sum of the powers output by the L second conversion units and the N-L first conversion units is greater than or equal to the power consumption of the data device 101, so that the data device 101 can maintain normal operation.

Further, the first power supply module 1031 and the second power supply module 1032 may share one power source, and this power source may be a battery built in the UPS 103, or may be a battery independent from the UPS 103, and the application is not limited in this specification.

When the commercial power is interrupted, the first battery outputs direct current, and the first conversion unit converts the direct current output by the first battery into alternating current (first alternating current) and then inputs the alternating current into the data device 101; the second conversion unit also converts the dc power output from the first battery into ac power (second ac power) and then inputs the ac power to the air conditioner 102.

Specifically, each of the first conversion units may include a first rectifier and a first inverter, and each of the second conversion units may include a second rectifier and a second inverter.

When the commercial power is normal, the first rectifier converts the alternating current output by the commercial power into a first direct current, inputs part of the current in the first direct current to the first battery to charge the first battery, and the first inverter converts another part of the current in the first direct current into a third alternating current and inputs the third alternating current to the data device 101, so that the data device 101 can normally work.
