[0048] Computer room air conditioning is a special air conditioning system designed for precision electronic equipment environments such as data centers and server rooms. It is mainly used to control the temperature, humidity, and air cleanliness in the computer room, maintain a stable operating environment, and ensure the reliability and service life of the equipment.

[0049] Compared with household air conditioners or ordinary commercial air conditioners, computer room air conditioners have the following characteristics: 1. They are designed to operate continuously 24 hours a day, 365 days a year, and have redundant components (such as dual compressors and dual fans) with strong fault switching capabilities to ensure uninterrupted cooling. 2. They are equipped with multiple protection mechanisms (such as high-voltage protection and overheating protection) to reduce the risk of downtime. 3. In order to ensure the stable operation of information technology (IT) equipment by precisely controlling the ambient temperature, an integrated monitoring system is required to support remote management.

[0050] However, traditional computer room air conditioning control methods have the following problems: 1. After being turned on, the computer room air conditioner maintains a certain temperature continuously, which is not environmentally friendly; 2. The computer room air conditioner does not increase its operating power during off-peak electricity prices, which is not in line with the concept of conservation; 3. The temperature in the computer room rises rapidly and cannot be lowered in time; 4. When electricity prices are low, time is limited, and the lack of power storage makes it impossible to fully enjoy the low electricity prices; 5. Since it may take some time for the generator to start when the power grid is out, the battery can intervene in time to ensure the stability of the computer room ambient temperature.

[0051] Related technologies achieve feedback adjustment of the cooling of electrical equipment by obtaining the temperature of the environment surrounding the electrical equipment, thereby ensuring the accuracy of cooling. However, it is impossible to intelligently predict and lower the temperature in advance before the machine heats up quickly; it is impossible to increase the power of the computer room air conditioner in time before the electricity price peaks and valleys; and it is impossible to fully utilize the benefits brought by low electricity price periods.

[0052] In order to solve the above technical problems, the present application provides a control method, device, equipment, medium and product for a computer room air conditioner, which determines whether to use an external power grid or a battery for power supply based on the electricity price timing period and the battery power, thereby improving the flexibility of the power supply method, optimizing the efficiency of power use, and further saving electricity costs; on the other hand, according to the electricity price timing period and the computer room temperature, the air conditioner operating power is dynamically adjusted, which not only ensures that the computer room ambient temperature is always in the optimal state, but also makes full use of lower-priced electricity resources and effectively reduces electricity costs.

[0053] The control method of the computer room air conditioner provided in the embodiment of the present application is described in detail below.

[0054] Figure 1 This is a flow chart of the steps of a control method for a computer room air conditioner provided in an embodiment of the present application. The control method for a computer room air conditioner is applied to an air conditioner, such as Figure 1 As shown, the method may include the following steps.

[0055] Step 101: Obtain the current room temperature, electricity price time period, and battery power.

[0056] In the embodiment of the present application, the electricity price timing period includes a peak period or a valley period.

[0057] It's understandable that electricity price periods are set by power companies to rationalize pricing and guide user electricity usage. This is based on factors such as electricity demand and power supply costs during different times of the day, dividing the day into several time periods and setting electricity price standards for each time period. During peak hours, electricity prices are higher, as the power system's load is peaking, electricity demand is high, and power supply costs are relatively high. For example, peak hours may occur during daytime on weekdays, when industrial and commercial electricity consumption is high, and during the evening when residential electricity consumption is concentrated. During off-peak hours, electricity prices are lower. Off-peak hours occur when the power system load is low, electricity supply is relatively abundant, power supply costs are lower, and electricity prices are therefore lower. For example, from late night to early morning, when most users consume less electricity, electricity prices may be at off-peak times.

[0058] In one possible implementation, the electricity price time period is determined based on an electricity price change curve. The electricity price change curve has time as the horizontal axis and electricity price level as the vertical axis, and the fluctuations of the curve reflect the dynamic changes in electricity prices. The electricity price change curve can be pre-set in the controller of the computer room air conditioner or manually input, and this application does not impose any specific restrictions.

[0059] In one possible implementation, at least one natural day is divided into a peak period or a valley period according to changes in the historical electricity price change curve. For example, from 8 a.m. to 8 p.m., the electricity price is higher and the historical electricity price change curve rises faster, then 8 a.m. to 8 p.m. is divided into a peak period; from 8 p.m. to 8 a.m. the next day, the price is lower and the historical electricity price change curve drops more significantly, then 8 p.m. to 8 a.m. the next day is divided into a valley period.

[0060] In a possible implementation, the peak period or the valley period corresponding to the current moment in the historical electricity price change curve is used as the electricity price timing period at the current moment.

[0061] In the embodiment of the present application, the computer room temperature refers to the ambient temperature in the computer room.

[0062] In a possible implementation, the current temperature of the computer room is obtained through a temperature sensor.

[0063] In the embodiment of the present application, the battery is connected to the computer room air conditioner.

[0064] In a possible implementation, the battery is connected to the computer room air conditioner through a first control switch, and the battery is connected to the external power grid through a second control switch.

[0065] In one possible implementation, the current battery charge level is acquired using a Hall current sensor. For example, the Hall current sensor measures the battery charge and discharge current in real time and calculates the battery charge change using Coulomb integration.

[0066] In another possible implementation, the remaining capacity of the battery is determined based on the open circuit voltage of the battery by using the corresponding relationship between voltage and capacity. For example, the remaining capacity of the battery is estimated based on the battery characteristic curve and the open circuit voltage.

[0067] Step 102: Determine a target power supply mode for the computer room air conditioner based on the electricity price time period and the battery power level, and switch to the target power supply mode.

[0068] In an embodiment of the present application, the target power supply mode includes external grid power supply or battery power supply.

[0069] It is understandable that the external power grid is the regular power supply system for the computer room air conditioner, and the battery serves as the backup power supply system. When the external power grid interrupts power supply, the battery will immediately take over the power supply task to ensure the continuous operation of the computer room air conditioner and avoid potential damage caused by sudden power outages.

[0070] In some embodiments, step 102 may include: when the electricity price timing period is a low period and the battery power is less than or equal to the power threshold, determining that the air conditioner is powered by the external power grid; when the electricity price timing period is a peak period and the battery power is greater than the power threshold, determining that the air conditioner is powered by the battery.

[0071] Step 103: Adjust the operating power of the computer room air conditioner according to the electricity price time period and the computer room temperature.

[0072] In some embodiments, step 103 may include: when the electricity price timing period is a low period and the computer room temperature is greater than a first temperature range, increasing the operating power of the computer room air conditioner; when the electricity price timing period is a peak period and the computer room temperature is less than or equal to the first temperature range, reducing the operating power of the computer room air conditioner.

[0073] It is understandable that increasing the operating power of the computer room air conditioner during periods of low electricity prices and reducing the operating power of the computer room air conditioner during periods of high electricity prices can take advantage of the discounts brought by low electricity prices and save more energy.

[0074] To sum up, the control method of the computer room air conditioner in the embodiment of the present application, on the one hand, determines whether to supply power from the external power grid or the battery according to the electricity price timing period and the battery power, thereby improving the flexibility of the power supply mode, optimizing the efficiency of power use, and further saving electricity costs; on the other hand, dynamically adjusting the air conditioner operating power according to the electricity price timing period and the computer room temperature, not only ensures that the computer room ambient temperature is always in the optimal state, but also makes full use of lower-priced electricity resources and effectively reduces electricity costs.

[0075] Figure 2 This is a flowchart of the specific steps of a control method for a computer room air conditioner provided in an embodiment of the present application. Figure 2 As shown, the method may include the following steps.

[0076] Step 201: Obtain the current room temperature, electricity price time period, and battery power.

[0077] The method of this step has been described in the aforementioned step 101 and will not be repeated here.

[0078] Step 202: When the electricity price timing period is a peak period and the battery power level is greater than a power threshold, determine that the power supply mode of the computer room air conditioner is battery power supply.

[0079] In an embodiment of the present application, the power threshold may be 20% of the battery capacity, or the power threshold may be enough to power the computer room air conditioner for 5 hours, which is not limited in this application.

[0080] It is understandable that when the battery has power, using the battery to power the computer room air conditioning system during periods of high electricity prices can release the power stored in the battery when electricity prices are high, optimize energy utilization efficiency, and further save costs.

[0081] In some embodiments, the battery is connected to the computer room air conditioner through a first control switch, and the battery is connected to the external power grid through a second control switch. When the electricity price timing period is a peak period and the battery power is greater than the power threshold, the first control switch between the battery and the computer room air conditioner is closed, and the second control switch between the battery and the external power grid is disconnected.

[0082] In one possible implementation, after step 202, the computer room air conditioner control method may further include: detecting a battery charge; and switching the power supply mode from battery power to external power grid power when the battery charge is less than or equal to a second charge value, wherein the second charge value is less than a charge threshold.

[0083] In this way, during periods of high electricity prices, the battery power will not be completely exhausted. Since it may take some time for the generator to start when the power grid is out, the battery can serve as a backup power source to power the computer room air conditioner normally, ensuring the continuous operation of the computer room air conditioner and the stable ambient temperature of the computer room.

[0084] In some embodiments, the battery capacity of the storage battery is calculated based on the air conditioning power, the backup time, the battery type, the discharge efficiency, and the discharge depth.

[0085] For example, if the air conditioner's active power is 15 kilowatts (kW), the standby time is 3 hours, the battery pack voltage is 240 volts (V), the discharge efficiency is 85%, and the depth of discharge is 80%, then the energy demand is 15 × 3 = 45 kW. Using the discharge efficiency to correct the energy demand, the total energy is 45 ÷ 85% = 52.94 kW. The battery capacity is (52.94 × 1000) ÷ (204 × 80%) ≈ 275.7 ampere-hours (Ah). Therefore, a battery cell of 20 12V / 300Ah lead-acid batteries can be selected, which will slightly exceed the calculated capacity to provide a safety margin. In actual configurations, standard 12V / 100Ah and 12V / 200Ah batteries can also be used, connecting them in series or parallel to achieve the target capacity.

[0086] Step 203: When the electricity price timing period is a low period, or the battery power level is less than or equal to the power level threshold, determine that the power supply mode of the computer room air conditioner is external grid power supply.

[0087] In a possible implementation, the external grid power supply includes connecting the mains power to the hardware equipment of the computer room air conditioner through the power system.

[0088] It is understandable that when the battery power is low, or during periods of low electricity prices, using external power grid power to power the computer room air conditioning system can fully utilize low-priced electricity resources and effectively reduce operating costs.

[0089] In some embodiments, the battery and the computer room air conditioner are connected through a first control switch. When the electricity price timing period is peak and the battery power is greater than the power threshold, when the power grid is supplying power to the computer room air conditioner, the first control switch between the battery and the computer room air conditioner is disconnected.

[0090] Through the above technical solution, when the battery has power, the computer room air conditioning system is powered by the battery during periods of high electricity prices. This can release the power stored in the battery when electricity prices are high, optimize energy utilization efficiency, and further save costs. When the battery power is low, or during periods of low electricity prices, the computer room air conditioning system is powered by external power grid power supply, which can fully utilize low-priced electricity resources and effectively reduce operating costs.

[0091] In some embodiments, after step 203, the control method of the computer room air conditioner may further include: charging the battery through an external power grid connected to the battery when the electricity price timing period is a low period and the battery power is less than or equal to the power threshold.

[0092] For example, when the battery is not fully charged and the electricity price is low, the power grid charges the battery and supplies power to the computer room air conditioner at the same time. At this time, the first control switch between the battery and the computer room air conditioner is disconnected, the second control switch between the battery and the external power grid is closed, and the third control switch between the external power grid and the computer room air conditioner is in a closed state.

[0093] Through the above technical solution, during the period of low electricity prices, not only the external power grid is used to power the computer room air conditioner, but also the external power grid is used to charge the battery. The battery is charged during the period of low electricity prices and discharged during the period of high electricity prices, which can make full use of low-priced electricity resources and effectively reduce operating costs.

[0094] In some embodiments, after step 203, the control method of the computer room air conditioner may further include: switching the power supply mode from external grid power supply to battery power supply when the external grid fails or a power outage occurs.

[0095] Understandably, servers and network equipment in the computer room are temperature-sensitive. Brief periods of high temperatures can trigger overheating alarms, performance degradation, or even shutdown, leading to data loss or business interruption. Battery backup power can maintain air conditioning operation and prevent ambient temperature runaway. If the utility power is interrupted due to a fault, maintenance, or natural disaster (such as a power outage), the battery can immediately power the air conditioning system, ensuring uninterrupted cooling and extending emergency repair time.

[0096] In one possible implementation, switching the power supply mode from external grid power supply to battery power supply may include: controlling the circuit between the external grid and the computer room air conditioner to be disconnected so that the external grid stops supplying power to the computer room air conditioner, and controlling the circuit between the battery and the computer room air conditioner to be connected so that the battery supplies power to the computer room air conditioner.

[0097] Exemplarily, the external power grid and the computer room air conditioner are connected via a third control switch, and the battery and the computer room air conditioner are connected via a first control switch. In the event of a failure or power outage in the external power grid, the third control switch is disconnected and the first control switch is closed, so that the power supply mode of the computer room air conditioner is switched from external power grid power supply to battery power supply.

[0098] Through the above technical solution, by setting up a battery as a backup power system, when the external power grid is interrupted, the battery will immediately take over the power supply task, ensuring the continuous operation of the computer room air conditioner and avoiding potential damage caused by sudden power outages.

[0099] Step 204: When the electricity price timing period is a low period and the temperature of the computer room is greater than the first temperature range, increase the operating power of the computer room air conditioner.

[0100] In some embodiments, the first temperature range is determined based on the type of computer room and the season. Different computer room levels have different ambient temperature requirements, which are adjusted based on actual needs.

[0101] For example, for a Class A computer room, when the season is summer, the first temperature range is 24±1°C; when the season is winter, the first temperature range is 20±1°C, with a fluctuation range strictly controlled within ±1°C. For a Class B computer room, when the season is summer, the first temperature range is 24±2°C; when the season is winter, the first temperature range is 20±2°C, with a fluctuation range of ±2°C allowed.

[0102] In a possible implementation, the first temperature range is obtained based on the type of the computer room. For example, if the computer room type is a Class C computer room, the first temperature range is 15-28°C.

[0103] In a possible implementation, increasing the operating power of the computer room air conditioner may include increasing the operating power of the computer room air conditioner to a maximum power so that the computer room maintains a suitable temperature.

[0104] It should be noted that after step 203 , step 204 may be executed, and sub-steps 2041 and 2042 may also be executed.

[0105] Sub-step 2041: When the electricity price timing period is a valley period and the temperature of the computer room is greater than a first temperature range, determine a first adjustment time according to the difference between the start time of the valley period and the first duration; the first adjustment time is earlier than the start time of the valley period;

[0106] Sub-step 2042: reducing the operating power of the computer room air conditioner at the first adjustment time, and increasing the operating power of the computer room air conditioner at the start time of the off-peak period.

[0107] It is understandable that increasing the power of the computer room air conditioner in time before the peak electricity price period arrives can lower the temperature in advance and make full use of the benefits brought by the low electricity price period.

[0108] In the embodiment of the present application, the first duration may be one hour, or the first duration may be 10 minutes, which is not specifically limited in the embodiment of the present application.

[0109] In a possible implementation, the first adjustment time is obtained by subtracting the first duration from the start time of the valley period.

[0110] Exemplarily, the starting time of the low-peak period is 8:00 am, the first duration is 10 minutes, and then the first adjustment time is 7:50 am.

[0111] In a possible implementation, reducing the operating power of the computer room air conditioner at the first adjustment time includes reducing the operating power of the computer room air conditioner by one or more levels at the first adjustment time.

[0112] In a possible implementation, increasing the operating power of the computer room air conditioner at the start of the off-peak period includes increasing the operating power of the computer room air conditioner to a maximum power at the start of the off-peak period to maintain a suitable temperature in the computer room.

[0113] For example, the electricity price is lower from 8 pm to 8 am the next day. At 7:50 pm, the air conditioning power is reduced to meet the working environment temperature of the computer room, and the air conditioning power is increased at 8 pm to quickly cool down.

[0114] In some embodiments, the control method for the computer room air conditioner further includes: obtaining a historical electricity price change curve; and dividing at least one natural day into a peak period or a valley period according to the historical electricity price change curve.

[0115] Through the above technical solution, before the arrival of the low electricity price period, the computer room air conditioner will reduce the operating power in advance, and increase the operating power of the computer room air conditioner at the beginning of the low electricity price period, thereby achieving the purpose of saving expenses and reducing operating costs.

[0116] Step 205: When the electricity price timing period is a peak period and the temperature of the computer room is less than or equal to the first temperature range, reduce the operating power of the computer room air conditioner.

[0117] In a possible implementation, reducing the operating power of the computer room air conditioner may include reducing the operating power of the computer room air conditioner by one or more levels.

[0118] It should be noted that after step 204 , step 205 may be executed, and sub-steps 2051 and 2052 may also be executed.

[0119] Sub-step 2051: determining a third adjustment time according to the difference between the end time of the valley period and the first duration; wherein the third adjustment time is earlier than the end time of the valley period;

[0120] Sub-step 2052: increasing the operating power of the computer room air conditioner at the third adjustment time, and reducing the operating power of the computer room air conditioner at the end of the off-peak period.

[0121] In a possible implementation, the first duration is subtracted from the end time of the valley period to obtain the third adjustment time.

[0122] For example, the end time of the off-peak period is 8:00 a.m., and the first duration is 10 minutes. Then, the third adjustment time is 7:50 a.m. At 7:50 a.m., the air conditioning power of the computer room is increased and the temperature is reduced to the lowest temperature without affecting the working environment of the equipment in the computer room.

[0123] In a possible implementation, increasing the operating power of the computer room air conditioner at the third adjustment time includes increasing the operating power of the computer room air conditioner to a maximum power at the third adjustment time.

[0124] In a possible implementation, reducing the operating power of the computer room air conditioner at the end of the off-peak period includes reducing the operating power of the computer room air conditioner by one or more levels at the end of the off-peak period.

[0125] Through the above technical solution, by optimizing the control strategy of the operating power of the computer room air conditioner, not only the benefits brought by low electricity prices are extended, but also the stability and reliability of the computer room ambient temperature are ensured while users save money.

[0126] In some embodiments, after step 205, the computer room control method may further include: when the temperature of the computer room is greater than or equal to a second temperature threshold, increasing the operating power of the computer room air conditioner.

[0127] In an embodiment of the present application, the second temperature threshold is greater than the first temperature range, and the second temperature threshold is the upper limit of the operating temperature of the machine in the computer room.

[0128] It is understandable that extreme weather conditions, overheated ambient temperatures, or a sudden surge in user usage can easily lead to higher ambient temperatures in the computer room. When the temperature exceeds the operating threshold temperature of the computer room machines, the computer room air conditioning power will be increased to the maximum value and the temperature will be adjusted to a temperature suitable for the operation of the computer room machines.

[0129] Through the above technical solution, when the temperature in the computer room is greater than or equal to the upper limit of the operating temperature of the computer room machine, the power of the computer room air conditioner is increased to the maximum value to control the increase of the power of the computer room air conditioner, thereby achieving the purpose of cooling and protecting the safe operation of the computer room equipment.

[0130] In some embodiments, after step 205, the computer room control method may further include:

[0131] Sub-step 206: obtaining a historical temperature change curve of the computer room;

[0132] Sub-step 207: determining a temperature sudden change period based on the historical temperature change curve; the temperature change rate during the temperature sudden change period is greater than a preset rate threshold;

[0133] Sub-step 208: determining a second adjustment time according to the difference between the start time of the sudden temperature change period and the second duration; wherein the second adjustment time is earlier than the start time of the sudden temperature change period;

[0134] Sub-step 209: increasing the operating power of the computer room air conditioner at the second adjustment time, and reducing the operating power of the computer room air conditioner at the end of the temperature sudden change period.

[0135] In a possible implementation, the second adjustment time is obtained by subtracting the second duration from the start time of the temperature sudden change period.

[0136] In an embodiment of the present application, the preset rate threshold may be 5 degrees Celsius per hour, the second time length may be 0.5 hours, or the second time length may be 15 minutes, which is not specifically limited in the embodiment of the present application.

[0137] In one possible implementation, the historical temperature change curve can be pre-set in the controller of the computer room air conditioner. The historical temperature change curve can also be manually input data, which is not specifically limited in this application. The historical temperature change curve has time as the horizontal axis and temperature as the vertical axis, and the fluctuations of the curve reflect the dynamic changes in temperature.

[0138] In a possible implementation, the temperature at the current moment is obtained from a historical temperature change curve.

[0139] In one possible implementation, the historical temperature change curve is divided into multiple time periods. Based on the tangent of the historical temperature change curve, the temperature change rates corresponding to the multiple moments included in each time period are determined. The time period in which the temperature change rates corresponding to all moments are greater than a preset rate threshold is considered a temperature sudden change period. It is understood that when the temperature change rate is large, the temperature changes rapidly, and early cooling is required to meet the room's ambient temperature.

[0140] In a possible implementation, increasing the operating power of the computer room air conditioner at the second adjustment time includes: increasing the operating power of the computer room air conditioner to a maximum power at the second adjustment time.

[0141] For example, in a computer server room, the temperature changes most rapidly between 11:30 and 13:30, and the second time period is 15 minutes. Therefore, in order to ensure that the temperature in the computer room remains stable, the air conditioning power in the computer room can be increased in advance at 11:15 to match the ambient temperature in the computer room. For example, the operating power of the air conditioning in the computer room can be increased to the maximum power at 11:15.

[0142] In a possible implementation, reducing the operating power of the computer room air conditioner at the end of the temperature sudden change period includes reducing the operating power of the computer room air conditioner by one or more levels at the end of the temperature sudden change period.

[0143] For example, in a computer server room, the temperature changes rapidly between 11:30 and 13:30. The air conditioning power of the computer room can be reduced at 13:30. For example, the operating power of the air conditioning in the computer room can be reduced by one or more gears at 13:30.

[0144] In one possible implementation, after sub-step 208, the above-mentioned computer room control method may further include: determining a fourth adjustment time based on the difference between the end time of the temperature sudden change period and the second time length; the fourth adjustment time is earlier than the end time of the temperature sudden change period; increasing the operating power of the computer room air conditioner at the second adjustment time, and reducing the operating power of the computer room air conditioner at the fourth adjustment time.

[0145] In a possible implementation, increasing the operating power of the computer room air conditioner at the second adjustment time includes: increasing the operating power of the computer room air conditioner to a maximum power at the second adjustment time.

[0146] For example, in a computer server room, the temperature changes most rapidly between 11:30 and 13:30, and the second time period is 15 minutes. Therefore, in order to ensure that the temperature in the computer room remains stable, the air conditioning power in the computer room can be increased in advance at 11:15 to match the ambient temperature in the computer room. For example, the operating power of the air conditioning in the computer room can be increased to the maximum power at 11:15.

[0147] In a possible implementation, reducing the operating power of the computer room air conditioner at the fourth adjustment time includes reducing the operating power of the computer room air conditioner by one or more levels at the fourth adjustment time.

[0148] In a possible implementation, the fourth adjustment time is obtained by subtracting the second duration from the end time of the temperature sudden change period.

[0149] For example, in a computer server room, the temperature changes rapidly between 11:30 and 13:30, the second time period is 15 minutes, and the fourth moment is 13:15. For example, at 13:15, the operating power of the air conditioner in the computer room is reduced by one or more gears.

[0150] Through the above technical solution, the temperature changes of the machines in the computer room can be collected in real time, the temperature of the computer room air conditioner can be adjusted in advance, and the temperature can be lowered in time during the period when the temperature in the computer room rises faster to ensure that the operating temperature requirements of the machines are met and that the ambient temperature of the computer room is always maintained in an ideal state to meet the machine operation needs.

[0151] In summary, the control method for the computer room air conditioner in the embodiment of the present application, first, monitors the ambient temperature in the computer room in real time through a temperature sensor to ensure that the equipment in the computer room is always in an ideal operating environment. Secondly, the system intelligently regulates the charging and discharging behavior of the battery according to the electricity price fluctuation curve, charging during the low electricity price period and discharging during the peak electricity price period, thereby maximizing the economic benefits brought by the low electricity price. Thirdly, the system dynamically adjusts the operating power of the air-conditioning system according to the temperature change curve of the computer room to ensure that the ambient temperature of the computer room is always maintained at the optimal state. Finally, when the external power grid fails or the power outage occurs, the battery will immediately switch to the power supply mode to ensure the continuous operation of the computer room air conditioning system and avoid potential damage caused by sudden power outages.

The computer rooms can include different types of computer rooms, wherein each computer room is equipped with an industrial air conditioner as the computer room air conditioner.

[0154] In some embodiments, industrial air conditioners achieve precise control of parameters such as temperature, humidity, and cleanliness of the industrial environment through compression, condensation, throttling, and evaporation of refrigerants, as well as filtration, cooling, heating, humidification / dehumidification of air.

[0155] In the embodiment of the present application, when the existing computer room is expanded or the old computer room is upgraded and renovated, by adding the control system of the computer room air conditioner provided in the embodiment of the present application, adding batteries to each computer room, and cooperating with the real-time adjustment and precise cooling air conditioning control scheme described in the embodiment of the present invention, it is possible to meet the heat dissipation needs of the computer room without replacing high-cooling capacity air conditioners or increasing the number of computer room air conditioners.

[0156] In summary, the control system for the computer room air conditioner in the embodiment of the present application, on the one hand, determines whether to supply power from the external power grid or the battery based on the electricity price time period and the battery power level, thereby increasing the flexibility of the power supply method, optimizing energy efficiency, and further saving costs. On the other hand, the control system dynamically adjusts the air conditioner operating power based on the electricity price time period and the computer room temperature, which not only ensures that the computer room ambient temperature is always at an optimal state, but also fully utilizes lower-priced electricity resources, effectively reducing operating costs. The entire system is based on the core concept of green environmental protection. By optimizing the battery charging and discharging strategy, it not only extends the benefits brought by low electricity prices, but also ensures the stability and reliability of the computer room ambient temperature while saving users money.
