Each UPS is respectively connected with the IT equipment and the control unit, and each UPS is connected with the mains supply.
Each air conditioner power supply mode switching unit is connected with the UPS, and each air conditioner power supply mode switching unit is only connected with one UPS.
For example, if the number of the uninterruptible power supplies UPS is 2 and the number of the air-conditioner power supply mode switching units and the number of the air-conditioners are 1, the connection relationship between the UPS and the IT equipment and the control unit is shown in fig. 2.

In step S102, if the remaining battery power is greater than the preset power threshold, the maximum number of turned-on air conditioners is determined according to the preset capacity of the UPS, the preset operating power of the IT equipment, and the preset refrigeration power of the air conditioners.
Optionally, if the remaining battery capacity is not greater than the preset capacity threshold, IT indicates that the available capacity of the UPS is low and cannot meet the power consumption requirement of air-conditioning refrigeration, and the control unit does not turn on any air conditioner, so that the UPS only supplies power to the IT equipment, the service time of the remaining battery capacity is prolonged, and the situation that the IT equipment cannot normally work due to insufficient power supply of the UPS is avoided.
In this embodiment, if the remaining battery capacity is greater than the preset capacity threshold, IT indicates that the control unit may further turn on the air conditioner to cool the air conditioner, and the UPS may further supply power to the turned-on air conditioner, that is, the UPS may further have electric power required for cooling the air conditioner, and determines the maximum turning-on number of the air conditioner according to the preset capacity of the UPS, the preset operating power of the IT device, and the preset cooling power of the air conditioner.

In this embodiment, when the utility power is abnormal, the control unit controls the number of the air conditioners to be turned on by controlling the number of the air conditioner power supply mode switching units to be switched to the uninterruptible power supply mode, and the number of the air conditioner power supply mode switching units to be switched to the uninterruptible power supply mode is the maximum number of the air conditioners to be turned on.
In this embodiment, when the utility power supply is abnormal, the current battery residual capacity of the UPS is acquired, the battery residual capacity is compared with a preset capacity threshold value, if the battery residual capacity is greater than the preset capacity threshold value, IT indicates that the UPS can also supply power to the air conditioner, IT is determined that the number of the air conditioners which are turned on at most is determined, the actual number of the air conditioners which are turned on is determined according to the preset refrigeration power of the air conditioners and the maximum number of the air conditioners which are turned on at most, and the air conditioners with corresponding numbers are turned on continuously according to the actual number of the air conditioners, so that the air conditioners can still continue to refrigerate when the utility power supply is abnormal, and the situation that the IT equipment is overheated and.

in step S301, the power consumption of the IT device within the preset time is calculated according to the preset operating power.
In this embodiment, the product of the preset operating power of the IT device and the preset time is calculated to obtain the power consumption of the IT device within the preset time, and the preset time may be very small, for example, 1 second, so that the power consumption of the IT device within the preset time may be estimated as the current power consumption of the IT device.
Wherein, the power consumption is the power consumption.
In step S302, a difference between the remaining battery capacity and the power consumption of the IT device is calculated to determine the available air conditioner capacity.
In this embodiment, a difference between the remaining capacity of the battery and the current power consumption of the IT device is calculated to obtain the current available capacity of the air conditioner.
In step S303, the power consumption of the air conditioner for a preset time is calculated according to the preset cooling power.
In this embodiment, the product of the preset cooling power of the air conditioner and the preset time is calculated to obtain the power consumption of the air conditioner within the preset time, and the power consumption of the air conditioner within the preset time can be estimated as the cooling power consumption of the air conditioner.
In step S304, a ratio of the air conditioner available power to the air conditioner power consumption is calculated, and the air conditioner on number is determined.
In this embodiment, the ratio of the current air conditioner available power to the air conditioner power consumption is calculated to obtain the number of the air conditioners turned on, that is, the number of the air conditioners capable of supporting the air conditioners for refrigeration.
In step S305, if the number of turned-on air conditioners is less than the maximum number of turned-on air conditioners, it is determined that the actual number of turned-on air conditioners is the number of turned-on air conditioners.
In this embodiment, if the number of the turned-on air conditioners is less than the maximum number of the turned-on air conditioners, it indicates that the current available electric quantity of the air conditioners can support the number of the turned-on air conditioners for refrigeration, and the UPS can drive the number of the turned-on air conditioners to operate.
In step S306, if the number of turned-on air conditioners is not less than the maximum number of turned-on air conditioners, it is determined that the actual number of turned-on air conditioners is the maximum number of turned-on air conditioners.
In this embodiment, if the number of turned-on air conditioners is not less than the maximum number of turned-on air conditioners, it indicates that although the current available electric quantity of the air conditioners can support the number of turned-on air conditioners for cooling, the maximum number of turned-on air conditioners is used as the actual number of turned-on air conditioners to avoid overload of the UPS because the UPS has limited load capacity, i.e., limited capacity, and cannot drive the number of turned-on air conditioners.
In the embodiment, the power consumption of the IT equipment and the air conditioner is calculated, the available power of the air conditioner is calculated according to the residual power of the battery and the power consumption of the IT equipment, the opening number of the air conditioner is obtained according to the available power of the air conditioner and the power consumption of the air conditioner, the opening number of the air conditioner is compared with the actual opening number of the air conditioner, and the actual opening number of the air conditioner is finally determined, so that the overload phenomenon of the UPS is effectively avoided.
