[0002] Computer room air conditioners, also known as precision air conditioners or constant temperature and humidity air conditioners, are air conditioning systems designed for computer rooms, data centers and other places with extremely high environmental requirements. Equipment in the computer room (such as servers, storage devices, network equipment, etc.) will generate a lot of heat during operation. If the temperature is too high, it may cause equipment performance to decline, stability to deteriorate, and even cause failures.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention discloses a computer room air conditioning control method, system, computer equipment and storage medium. The method sets a first air conditioning group with higher energy consumption and a second air conditioning group with lower energy consumption in the computer room, and then dynamically controls the first air conditioning device in the first air conditioning group and the second air conditioning device in the second air conditioning group to turn on or off based on temperature data and humidity data collected by temperature and humidity sensors distributed at different positions in the computer room, so as to control the temperature and humidity in the computer room. Compared with the prior art in which the temperature and humidity in the computer room are controlled by turning on all air conditioners, the air conditioning energy consumption in the computer room is reduced, and energy-saving control of the computer room air conditioner is achieved. The method is explained below through specific embodiments.

[0021] like Figure 1 FIG. 1 is a flowchart of a method for controlling a computer room air conditioner disclosed in an embodiment of the present invention. The method is applied in an air conditioning control system, such as a computer room air conditioning control system. The method in this embodiment includes the following steps: S101: Acquire temperature data and humidity data collected by temperature and humidity sensors distributed at different locations in the computer room in real time.

[0022] Among them, the temperature and humidity sensor is responsible for collecting temperature data and humidity data in the computer room, and the temperature data can be relative humidity. Temperature and humidity sensors are respectively set at different locations in the computer room, and temperature data and humidity data at different locations in the computer room can be collected. It should be understood that for computer rooms with larger spatial areas, there may be certain differences in temperature and humidity at different locations in the computer room. For example, the location with a higher server density in the computer room may have a higher temperature, and the location with a lower server density may have a lower temperature. Therefore, it is necessary to set temperature and humidity sensors at different locations in the computer room, that is, each temperature and humidity sensor will collect a temperature data and a humidity data, thereby more comprehensively monitoring the temperature data and humidity data in the computer room.

[0023] S102: Dynamically control the first air-conditioning device in the first air-conditioning group and the second air-conditioning device in the second air-conditioning group to turn on or off according to changes in the temperature data and the humidity data, so as to control the temperature and humidity in the computer room.

[0024] The power consumption of the second air-conditioning device is lower than the power consumption of the first air-conditioning device.

[0025] In a specific implementation, the first air conditioning device in this embodiment can be a precision air conditioner for a computer room, and the second air conditioning device can be a multi-joint fluorine pump air conditioner, wherein the precision air conditioner for a computer room can realize precise control of the humidity and temperature in the computer room, and the multi-joint fluorine pump air conditioner consumes less power than the precision air conditioner for a computer room. When the multi-joint fluorine pump air conditioner is used to cool and dehumidify the computer room, the precision air conditioner for the computer room can assist in controlling the humidity and temperature in the computer room. Therefore, through the mutual cooperation of the first air conditioning device and the second air conditioning device, not only the expected cooling and dehumidification effects can be achieved, but also the purpose of reducing the power consumption of the air conditioner can be achieved.

[0026] Specifically, in this embodiment, different control strategies may be adopted for the first air-conditioning device in the first air-conditioning group and the second air-conditioning device in the second air-conditioning group according to the difference in the collected humidity data and temperature data, which may be specifically as follows: In one embodiment, step S102 in this embodiment can be implemented by the following steps: Figure 2 As shown: S201: When the numerical maximum humidity data is greater than or equal to a preset first humidity threshold, all first air-conditioning devices are controlled to turn on to cool and dehumidify the computer room.

[0027] It should be understood that when the maximum humidity data is greater than or equal to the preset first humidity threshold, it means that the humidity of the air in the computer room exceeds the preset humidity range and rapid dehumidification is required. Therefore, all the first air-conditioning devices are controlled to turn on.

[0028] Obtain humidity data collected by temperature and humidity sensors at different locations in the computer room, filter out the humidity data with the largest value, and determine whether the maximum humidity data is greater than or equal to a preset first humidity threshold. When the maximum humidity data is greater than or equal to the preset first humidity threshold, control all first air-conditioning devices to turn on to cool and dehumidify the computer room.

[0029] In a specific implementation, the first air conditioning devices in this embodiment are all connected to a power controller. When the first air conditioning devices need to be controlled to be turned on, the power controllers corresponding to all the first air conditioning devices need to be closed first, and then a start instruction is issued to each first air conditioning device. When the first air conditioning device receives the start instruction, all the air conditioning devices are turned on to cool and dehumidify the computer room. In this way, all the first air conditioning devices can be controlled to be turned on to cool and dehumidify the computer room.

[0030] S202: Real-time monitoring of humidity data to see whether it is less than a preset second humidity threshold.

[0031] The second humidity threshold is smaller than the first humidity threshold.

[0032] It should be understood that after all the first air-conditioning devices are turned on, dehumidification and cooling will be continuously performed, and the humidity data collected by the temperature and humidity sensor will also change continuously, that is, as the first air-conditioning devices continue to dehumidify, the humidity data collected by the temperature and humidity sensor will continue to decrease.

[0033] After all the first air-conditioning devices are turned on, the humidity data collected by each temperature and humidity sensor is obtained in real time, and the maximum humidity data is determined from the humidity data. When the maximum humidity data collected is less than the second humidity threshold, all the second air-conditioning devices are controlled to be turned on, and the average temperature data of the computer room is calculated based on the temperature data. That is to say, if the maximum humidity data collected is greater than the second humidity threshold, the first air-conditioning device is used to cool and dehumidify the computer room until the maximum humidity data collected is less than the second humidity threshold, and all the second air-conditioning devices are controlled to be turned on, and the average temperature data of the computer room is calculated based on the temperature data.

[0034] S203: When the humidity data is less than the second humidity threshold, all second air-conditioning devices are controlled to turn on, and average temperature data of the computer room is calculated based on the temperature data.

[0035] In a specific implementation, when the second air-conditioning device in this embodiment is a multi-link fluorine pump air-conditioning device, the second air-conditioning device may have an outdoor unit and multiple indoor units, each of which may be installed in different areas of the machine room, and one indoor unit may be considered as one second air-conditioning device, that is, turning on the multi-link fluorine pump air-conditioning device may be considered as turning on all the second air-conditioning devices. In addition, the temperature data in this embodiment is also the temperature data collected in real time, that is, the temperature data collected by each temperature and humidity sensor when the humidity data is less than the second humidity threshold, and the average value of all temperature data is calculated to obtain the average temperature data.

[0036] S204: If the average temperature data is less than a preset first temperature threshold, each first air-conditioning device is dynamically controlled to be turned off according to the temperature data collected in real time by each temperature and humidity sensor.

[0037] If the average temperature data is less than the first temperature threshold, it means that the temperature in the machine room has reached the required temperature. Therefore, it is possible to dynamically control each first air-conditioning device to shut down according to the temperature data collected in real time by each temperature and humidity sensor, thereby achieving the purpose of reducing energy consumption; if the average temperature data is greater than the first temperature threshold, wait for the first air-conditioning device to continue cooling until the average temperature data is less than the first temperature threshold, and dynamically control each first air-conditioning device to shut down according to the temperature data collected in real time by each temperature and humidity sensor. Among them, the first temperature threshold includes but is not limited to 27°C, 28°C, etc., and the specific value of the first temperature threshold is not limited in this embodiment.

[0038] In one embodiment, in this embodiment, each first air conditioning device may be dynamically controlled to be turned off in the following manner: Figure 3 As shown: S301: Determine that the temperature and humidity sensor corresponding to the temperature data with the smallest value is the target sensor.

[0039] When the maximum humidity data collected by each temperature and humidity sensor is less than the second humidity threshold, the temperature data collected by each temperature and humidity sensor is obtained, and the temperature and humidity sensor corresponding to the temperature data with the smallest value is determined as the target sensor.

[0040] S302: Control a first air conditioning device closest to the target sensor to shut down, and obtain temperature rise data of the target sensor within a preset first time period in real time.

[0041] In a specific implementation, each temperature and humidity sensor in this embodiment corresponds to a first air-conditioning device that is set nearby. Therefore, the first air-conditioning device closest to the target sensor can be determined, and then a shutdown command is sent to the first air-conditioning device to control the first air-conditioning device to shut down. In addition, when the first air-conditioning device is turned off, the temperature data collected by the target sensor at this time is recorded, and the temperature data collected by the target sensor is recorded again after the first time period, and the difference between the two collected temperature data is calculated to obtain the temperature rise data. Among them, the first time period can be 20 minutes, 30 minutes or 40 minutes, etc., which is not limited in this embodiment.

[0042] S303: When the temperature rise data is greater than or equal to the preset first temperature rise threshold, the first air-conditioning device closest to the target sensor is controlled to turn on again, and the temperature and humidity sensor corresponding to the temperature data with the smallest value is determined as the target sensor from the remaining temperature and humidity sensors.

[0043] It can be understood that when the temperature rise data is greater than or equal to the preset first temperature rise threshold, it means that the heat generation at the location of the target sensor is large, resulting in a rapid temperature rise, and the first air-conditioning device cannot be turned off. Therefore, the first air-conditioning device closest to the target sensor is reopened.

[0044] The temperature data collected by the remaining temperature sensors are obtained, and then the temperature data with the smallest value is determined again, and the temperature and humidity sensor corresponding to the temperature data with the smallest value is determined as the target sensor. In other words, when the target sensor is determined again, the temperature and humidity sensor previously determined as the target sensor will be excluded. After a target sensor is determined again, the process returns to step S302, that is, the first air-conditioning device closest to the target sensor is controlled to be turned off, and the temperature rise data of the target sensor within the preset first time period is obtained in real time.

[0045] S304: When the temperature rise data is less than the first temperature rise threshold, determine, from the remaining temperature and humidity sensors, the temperature and humidity sensor corresponding to the temperature data with the smallest value as the target sensor.

[0046] It can be understood that when the temperature rise data is less than the first temperature rise threshold, it means that the heat generation at the location of the target sensor is small. If the first air-conditioning device closest to the target sensor is turned off in time, the temperature at the location of the target sensor will not rise rapidly. Therefore, the first air-conditioning device can be kept turned off, and then the temperature data collected by the remaining temperature sensors are obtained. Then, a temperature data with the smallest value is determined again, and the temperature and humidity sensor corresponding to the temperature data with the smallest value is determined to be the target sensor. Return to execute step S302, that is, control the first air-conditioning device closest to the target sensor to turn off, and obtain the temperature rise data of the target sensor within the preset first time period in real time, and so on, until all target sensors are inspected and all first air-conditioning devices that can be turned off are determined.

[0047] To sum up, in this embodiment, by turning off the first air-conditioning equipment at the location with lower heat generation in the computer room, compared with turning on all the first air-conditioning equipment, not only can the temperature of the computer room be controlled, but the power consumption of the air-conditioning system in the computer room can also be reduced, thereby effectively reducing energy consumption and helping to improve the energy efficiency of the computer room.

[0048] In one embodiment, step S102 in this embodiment can also be implemented by the following steps: Figure 4 As shown: S401: When the humidity data with the largest value is less than a preset first humidity threshold, all second air-conditioning devices are controlled to turn on, and average temperature data of the computer room is calculated based on the temperature data.

[0049] It should be understood that when the maximum humidity data is less than the preset first humidity threshold, it means that the humidity of the air in the computer room is within the preset humidity range and no rapid dehumidification is required. Therefore, all the second air-conditioning devices are controlled to turn on.

[0050] The humidity data collected by the temperature and humidity sensors at different positions in the computer room are obtained, the humidity data with the largest value is screened out, and it is determined whether the largest humidity data is less than the preset first humidity threshold. When the largest humidity data is less than the first humidity threshold, all the second air-conditioning devices are controlled to turn on to cool and dehumidify the computer room. At the same time, the temperature data collected by the temperature and humidity sensors at different positions in the computer room are obtained, and the average value of all temperature data is calculated to obtain the average temperature data.

[0051] S402: Determine whether the average temperature data is greater than a preset second temperature threshold.

[0052] If the average temperature data is greater than the preset second temperature threshold, it means that only turning on the second air-conditioning device cannot achieve a good cooling effect, and the first air-conditioning device needs to be turned on, that is, each first air-conditioning device is dynamically controlled to be turned on according to the temperature data collected in real time by each temperature and humidity sensor; if the average temperature data is less than or equal to the preset second temperature threshold, it means that turning on the second air-conditioning device has achieved a good cooling effect, and there is no need to turn on the first air-conditioning device.

[0053] S403: If the average temperature data is greater than the second temperature threshold, each first air-conditioning device is dynamically controlled to be turned on according to the temperature data collected in real time by each temperature and humidity sensor.

[0054] In one embodiment, in this embodiment, each first air conditioning device can be dynamically controlled to be turned on according to the temperature data collected in real time by each temperature and humidity sensor in the following manner, such as Figure 5 As shown: S501: Determine that the temperature and humidity sensor corresponding to the temperature data with the largest value is the target sensor.

[0055] S502: Control the first air conditioning device closest to the target sensor to turn on.

[0056] When the maximum humidity data is less than the preset first humidity threshold, the temperature data collected by each temperature and humidity sensor is determined as the target sensor. At this time, the first air conditioning device closest to the target sensor is controlled to start.

[0057] It can be understood that, under normal circumstances, when the first air-conditioning device closest to the target sensor is turned on, the temperature near the target sensor will inevitably drop. At this time, the value of the temperature data collected by the target sensor will inevitably decrease. Thus, the purpose of lowering the highest temperature data collected by all temperature and humidity sensors can be achieved.

[0058] S503: When the on-time of the first air-conditioning device closest to the target sensor reaches the preset second time length, the temperature data collected by all temperature and humidity sensors are obtained, and it is determined whether the temperature data with the largest value is greater than the preset third temperature threshold, and whether the temperature data with the largest value is less than the preset fourth temperature threshold.

[0059] The fourth temperature threshold is less than the third temperature threshold In a specific implementation, the second duration in this embodiment can be any duration such as 20 minutes, 30 minutes or 40 minutes, and the specific duration of the second duration is not limited in this embodiment. When the opening time of the first air-conditioning device closest to the target sensor reaches the preset second duration, the first air-conditioning device has fully exerted the cooling effect. At this time, the temperature data collected by all temperature and humidity sensors are re-acquired, and it is determined whether the temperature data with the largest value is greater than the preset third temperature threshold, and whether the temperature data with the largest value is less than the preset fourth temperature threshold. If the temperature data with the largest value is greater than the preset third temperature threshold, the temperature and humidity sensor corresponding to the temperature data with the largest value is determined as the target sensor from the remaining temperature and humidity sensors; if the temperature data with the largest value is less than the preset fourth temperature threshold, the first air-conditioning device closest to the target sensor is controlled to be turned off; if the temperature data with the largest value is greater than the third temperature threshold, and, when it is greater than the fourth temperature threshold, the existing working state of each first air-conditioning device is maintained.

[0060] S504: When the temperature data with the largest value is greater than a preset third temperature threshold, determine, from the remaining temperature and humidity sensors, the temperature and humidity sensor corresponding to the temperature data with the largest value as the target sensor.

[0061] When the temperature data with the largest value is greater than the preset third temperature threshold, it means that the temperature in the area where there are still temperature sensors is too high. Therefore, it is necessary to determine the temperature and humidity sensor corresponding to the temperature data with the largest value as the target sensor from the remaining temperature and humidity sensors, and return to execute step S502 and subsequent steps until the temperature data with the largest value is less than the fourth temperature threshold, and control the first air-conditioning device closest to the temperature and humidity sensor corresponding to the temperature data with the smallest value to be turned off.

[0062] S505: When the temperature data with the largest value is less than a preset fourth temperature threshold, each first air-conditioning device is dynamically controlled to be turned off according to the temperature data collected in real time by each temperature and humidity sensor.

[0063] It can be understood that when the temperature data with the largest value is less than the preset fourth temperature threshold, it means that the highest temperature in the computer room is already less than the fourth temperature threshold. At this time, the temperature data with the smallest value is even less than the fourth temperature threshold. Therefore, each first air-conditioning device can be dynamically controlled to be shut down based on the temperature data collected in real time by each temperature and humidity sensor.

[0064] According to the temperature data collected in real time by each temperature and humidity sensor, each first air conditioning device is dynamically controlled to be turned off, which is achieved through the following steps: Determine that the temperature and humidity sensor corresponding to the temperature data with the smallest value is the target sensor; control the first air-conditioning device closest to the target sensor to turn off, and obtain the temperature rise data of the target sensor within a preset first time period in real time; when the temperature rise data is greater than or equal to the preset first temperature rise threshold, re-control the first air-conditioning device closest to the target sensor to turn on, and determine the temperature and humidity sensor corresponding to the temperature data with the smallest value from the remaining temperature and humidity sensors as the target sensor; when the temperature rise data is less than the first temperature rise threshold, determine the temperature and humidity sensor corresponding to the temperature data with the smallest value from the remaining temperature and humidity sensors as the target sensor, and execute the target step: control the first air-conditioning device closest to the target sensor to turn off, and obtain the temperature rise data collected by the target sensor within the preset first time period in real time.

[0065] S506: When the temperature data with the largest value is less than the third temperature threshold and greater than the fourth temperature threshold, maintain the current working state of each first air-conditioning device.

[0066] When the temperature data with the largest value is less than the third temperature threshold and greater than the fourth temperature threshold, the next first air-conditioning device will not be turned on, and other first air-conditioning devices will not be turned off, that is, the current working state of each first air-conditioning device.

[0067] S404: If the average temperature data is less than or equal to the second temperature threshold, keep all the second air conditioning devices turned on.

[0068] When the average temperature data is less than or equal to the second temperature threshold, it means that only turning on the second air conditioner can keep the air in the computer room at a more suitable temperature. Therefore, there is no need to turn on the first air conditioner, and only the second air conditioner needs to be turned on.

[0069] To sum up, in this embodiment, by dynamically controlling the number of first air-conditioning devices that are turned on, only some of the first air-conditioning devices are always turned on in the computer room. Compared with turning on all the first air-conditioning devices every time, this not only reduces the consumption of electricity, but also helps to increase the service life of the first air-conditioning devices.

[0070] based on Figure 1 In the specific implementation, step S102 in this embodiment may also include the following steps: Figure 6 As shown: S601: When the humidity data is greater than or equal to a preset first humidity threshold, determine whether condensation occurs in the second air-conditioning device.

[0071] It should be understood that when the second air-conditioning device is a multi-fluorine pump air-conditioning device, condensation may occur in the second air-conditioning device. When condensation occurs in the second air-conditioning device, the relative humidity of the air in the computer room will increase significantly.

[0072] In a specific implementation, in this embodiment, the staff can observe whether the second air-conditioning device has condensation. When the staff presses the dehumidification button, it can be determined that the second air-conditioning device has condensation. Alternatively, the humidity data of the air outlet of the second air-conditioning device is obtained through the temperature and humidity sensor built into the second air-conditioning device. When the humidity data of the air outlet of the second air-conditioning device is greater than a preset humidity threshold, it is determined that the second air-conditioning device has condensation. It should be noted that the above are only some of the methods for determining whether the second air-conditioning device has condensation in this embodiment, and the method for determining whether the second air-conditioning device has condensation is not limited in this embodiment.

[0073] If condensation occurs in the second air-conditioning device, obtain the terminal air intake temperature, terminal air outlet temperature and terminal ambient humidity of each second air-conditioning device; if condensation does not occur in the second air-conditioning device, control all first air-conditioning devices to turn on to cool and dehumidify the computer room.

[0074] S602: If condensation occurs in the second air-conditioning device, obtain the terminal air intake temperature, terminal air outlet temperature and terminal ambient humidity of each second air-conditioning device.

[0075] In a specific implementation, in this embodiment, the terminal air outlet temperature and the terminal ambient humidity can be obtained by a temperature sensor and a humidity sensor provided at the terminal of the second air-conditioning device.

[0076] S603: Based on the terminal outlet air temperature and the terminal ambient humidity, query the ambient enthalpy-humidity diagram of the computer room to determine the dew point temperature of each second air-conditioning device.

[0077] The environmental enthalpy-humidity diagram is queried based on the terminal outlet air temperature and the terminal environmental humidity of each second air-conditioning device respectively to determine the dew point temperature of each second air-conditioning device.

[0078] Specifically, in this embodiment, the corresponding state point can be found in the enthalpy-humidity diagram according to the terminal outlet air temperature and the terminal ambient humidity, and then moved along the isohypeline (or isoenthalpy line) to the saturation line, and the intersection with the saturation line is the dew point temperature.

[0079] S604: Control the air intake temperature at the end of each second air-conditioning device to be above the dew point temperature, and dynamically control each first air-conditioning device to start according to the temperature data collected in real time by each temperature and humidity sensor.

[0080] In a specific implementation, in this embodiment, the minimum system pressure of each second air-conditioning device can be controlled separately to ensure that the terminal intake temperature of each second air-conditioning device is above the dew point temperature, thereby avoiding condensation at the terminal of the second air-conditioning device.

[0081] In addition, according to the temperature data collected in real time by each temperature and humidity sensor, dynamic control of turning on each first air conditioning device can be achieved in the following manner: determining the temperature and humidity sensor corresponding to the temperature data with the largest value as the target sensor; Control the first air-conditioning device closest to the target sensor to turn on; when the turning-on time of the first air-conditioning device closest to the target sensor reaches a preset second time, obtain the temperature data collected by all temperature and humidity sensors, and judge whether the temperature data with the largest value is greater than the preset third temperature threshold, and judge whether the temperature data with the largest value is less than the preset fourth temperature threshold, and the fourth temperature threshold is less than the third temperature threshold; when the temperature data with the largest value is greater than the preset third temperature threshold, determine from the remaining temperature and humidity sensors that the temperature and humidity sensor corresponding to the temperature data with the largest value is the target sensor; when the temperature data with the largest value is less than the preset fourth temperature threshold, dynamically control each first air-conditioning device to turn off according to the temperature data collected in real time by each temperature and humidity sensor; when the temperature data with the largest value is greater than the third temperature threshold, and greater than the fourth temperature threshold, maintain the existing working state of each first air-conditioning device.

[0082] based on Figure 1 In the specific implementation, this embodiment further includes the following steps after step S103: Figure 7 As shown: S103: After controlling the temperature and humidity in the computer room, record the temperature data, humidity data, operation status data of the first air-conditioning device and the second air-conditioning device, and energy efficiency data of the computer room.

[0083] S104: When the temperature and humidity sensors distributed at different positions in the computer room collect the same temperature data and humidity data again, the first air-conditioning device and the second air-conditioning device are controlled to be turned on or off according to the operation status data.

[0084] In a specific implementation, the temperature data and humidity data recorded in this embodiment are the temperature data and humidity data before the first air-conditioning device and the second air-conditioning device are controlled in the computer room, and the operating status data of the first air-conditioning device and the second air-conditioning device are the status data after the first air-conditioning device and the second air-conditioning device are controlled. When the temperature and humidity sensors distributed at different positions in the computer room collect the same temperature data and humidity data again, the first air-conditioning device and the second air-conditioning device are controlled to be turned on or off according to the operating status data. In addition, by recording the energy efficiency data of the computer room, the energy efficiency of the first air-conditioning device and the second air-conditioning device in the operating status data can be effectively reflected.

[0085] To sum up, in this embodiment, after controlling the temperature and humidity in the computer room, the temperature data, humidity data, and operating status data of the first air-conditioning device and the second air-conditioning device are recorded. When the temperature and humidity sensors distributed at different positions in the computer room collect the same temperature data and humidity data again, the first air-conditioning device and the second air-conditioning device can be quickly controlled to be turned on and off, which is conducive to improving the control efficiency of the air-conditioning equipment.
