It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the temperature regulation system may include: the precise air conditioner system comprises at least one precise air conditioner 101, a static pressure box and an air pipe (not shown in the figure), wherein in the embodiment, the precise air conditioner 101 is arranged in an IDC data machine room, and the precise air conditioner 101 can provide cold energy for the IDC data machine room through the static pressure box and the air pipe so as to adjust the temperature of the IDC data machine room. The air pipes can be provided with air supply pipes and/or air return pipes (not shown in the figure), and the arrangement mode of the air supply pipes in the air pipes can be arranged vertically above each row of racks according to the arrangement mode of the server racks in the IDC data machine room, so that cold air can be accurately sent to the racks.
In this embodiment, the precision air conditioner 101 may include: a master control board 1011, a temperature sensor 1012, at least one master compressor 1013, and at least one slave compressor 1014;

And the number of the main compressors 1013 and the slave compressors 1014 is defined according to the actual cooling demand of the data machine room: for the precision air conditioner 101 configured with a small redundancy or no redundancy machine room, the number of the main compressors 1013 may be greater than or equal to the number of the slave compressors 1014; for a machine room where a precision air conditioner is configured with large redundancy, the number of the main compressors 1013 may be smaller than the number of the sub compressors 1014.
In this embodiment, each precision air conditioner 1011 may have at least two compressors (i.e., a main compressor 1013 and a sub-compressor 1014), and when the precision air conditioner 1011 is in operation, the cold air is collected by the plenum box and then delivered to a target location by the air delivery pipe in the air pipe.
The main control board 1011 is configured to generate a start-up instruction when starting up the compressor, and send the start-up instruction to the main compressor 1013;
the main compressor 1013 is used for starting up and running when receiving the starting-up instruction, and providing cold energy for the data machine room;
it should be noted that, when the main compressor 1013 provides cooling capacity for the data machine room, the air supply temperature corresponding to the precision air conditioner 101 may be according to the formula Tsp＝Tspmid-a(Tspmax-Tspmin)(Tr-Trsp) And resetting in real time to ensure that the main compressor and the subsequent started slave compressor work cooperatively and regulate the temperature of the data machine room. The explanation of each parameter in the formula is referred to above, and the description is omitted here.
It should be understood that, in this embodiment, the main control board 1011 may be a controller or a processor for controlling the normal operation of the precision air conditioners, and of course, if a plurality of precision air conditioners 101 are installed in the same IDC data room, one external main control board 1011 may be reused for controlling the operation of each compressor in all the precision air conditioners.
Taking one master compressor and one slave compressor as an example, in a specific implementation, when the precision air conditioner 101 is started, the main control board 1011 generates a start instruction in response to a refrigeration instruction, and sends the generated start instruction to the master compressor 1013, so as to start the master compressor 1013 to produce cold air to reduce the temperature of the server in the IDC data room.
The temperature sensor 1012 is configured to collect a current return air temperature of the data center, and send the collected current return air temperature to the main control board 1011;
it should be noted that the number of the temperature sensors 1012 in this embodiment can be determined according to the situation, and they can be disposed in the IDC data room (for example, the east, west, south, north, and middle five directions of the IDC data room) to collect the current temperature (i.e., the current return air temperature) in the room. Of course, the specific location of the temperature sensor 1012 can be determined according to practical situations, and this embodiment is not limited thereto. In addition, in this embodiment, a temperature sensor 1012 for measuring the temperature of the air supply may be provided in the static pressure tank.
In a specific implementation, the temperature sensor 1012 collects the current return air temperature in the data room, and sends the collected current return air temperature to the main control board 1011.
The main control board 1011 is further configured to compare the current return air temperature with a first preset temperature, count the duration of the current return air temperature, and send a start instruction to the slave compressor 1014 when the current return air temperature is not lower than the first preset temperature and the duration exceeds the first preset duration;

In a specific implementation, when the main control board 1011 acquires the temperature collected by the temperature sensor 1012, the duration of the temperature is counted, and when it is detected that the current return air temperature is not lower than the first preset temperature and the duration exceeds the first preset duration, a start instruction is sent to the slave compressor 1014 to start the slave compressor 1014 to produce cold air to further reduce the temperature of the server in the IDC data machine room.
Further, in order to reduce the collection frequency of the temperature sensor 1012 and improve the service life of the temperature sensor 1012, in this embodiment, the collection frequency of the temperature sensor 1012 may be set to the first preset time duration, that is, when the current return air temperature obtained by the main control board 1011 continuously twice exceeds the first preset temperature, it may be determined that the second compressor (i.e., the slave compressor) needs to be started at this time to further adjust the temperature in the data room.
And the slave compressor 1014 is used for determining the current air supply temperature according to the starting instruction and adjusting the temperature based on the air supply temperature when receiving the starting instruction.

Specifically, after the slave compressor 1014 is started, the master control board 1011 may further continue to acquire the real-time temperature in the data machine room acquired by the temperature sensor 1012, that is, the current return air temperature, and when the master control board 1011 detects that the real-time temperature is lower than the second preset temperature (in this embodiment, the second preset temperature may be set to be lower than the first preset temperature by a certain threshold, such as 0.5 ℃, 1 ℃, and the like), the operation duration from the start of the operation of the slave compressor 1014 to the current time node is acquired, and if the operation duration is found to exceed a second preset duration (for example, 30 minutes), the master control board 1011 may send a shutdown instruction to the slave compressor 1014 to stop the operation of the slave compressor 1014.
In the embodiment, the current temperature of the data machine room is collected in real time, and the running state of each compressor is controlled according to the collected temperature and the running time of the compressor, so that the electric energy resource is effectively saved, the running time of each compressor is also controlled in a balanced manner, and the service life of the compressor is prolonged.
Based on the above embodiments, a third embodiment of the temperature adjustment system of the present invention is proposed.

Understandably, in order to guarantee the safety of the data computer room, the situation that the temperature in the data computer room is too high and potential safety hazards exist is avoided. In this embodiment, the temperature adjustment system further includes an alarm 104, and specifically, the main control board 1011 sends an alarm instruction to the alarm 104 when detecting that the current return air temperature is higher than a third preset temperature (e.g., 34 ℃), and the duration that the current return air temperature exceeds the third preset temperature exceeds the first preset duration (e.g., 1 minute), so that the alarm 104 sends an alarm prompt.
In this embodiment, the alarm 104 may be a buzzer or other devices with an alarm function, which is not limited in this embodiment.

Based on the above embodiments, a fourth embodiment of the temperature adjustment system of the present invention is proposed.
In this embodiment, the main control board 1011 is further configured to determine the current air supply set temperature according to an air supply temperature minimum set value, an air supply temperature middle set value, an air supply temperature maximum set value, an air return temperature set average value and the current air return temperature preset by a user, generate a start instruction according to the current air supply set temperature, and send the start instruction to the slave compressor 1014;

wherein, TspSetting temperature, T, for current supplyspminFor minimum set value of supply air temperature, TspmidFor a mid-set value of supply air temperature, TspmaxIs the maximum set value of the air supply temperature, TrAt the current return air temperature, TrspSetting an average value for the return air temperature, wherein a is a control coefficient and is more than 0 and less than 1.
Meanwhile, the supply air temperature setting value is reset according to the formula disclosed in the present embodiment based on the changed return air temperature, so that the cooling capacity of the precision air conditioner 101 is as close as possible to the actual thermal load.
In a specific implementation, a user may input various set parameter values (e.g., temperature and duration) into the main control board 1014 for storage through a human-computer interaction panel or a user interface of the precision air conditioner 101 in advance. Correspondingly, the main control board 1011 is further configured to respond to a parameter setting instruction input by a user, obtain a target parameter to be set and a target numerical value included in the parameter setting instruction, and set the target parameter according to the target numerical value.
The above embodiments are described in detail with reference to specific examples.
For example: four precise air conditioners are arranged in a certain data machine room, two compressors are arranged in each precise air conditioner, one compressor in each precise air conditioner is used as a main compressor, the other compressor is used as a slave compressor, the main compressor and the slave compressor can record the running time length according to the same main control board for alternation, and the alternation time length can also be set by a user; furthermore, the main control board can also finely control eight compressors in the four precise air conditioners, and the start-stop sequence and the running time of each compressor are adjusted.
When a server in a data machine room is low in energy and consumes time, all main compressors in four precise air conditioners are usually started, the minimum cold quantity requirement is guaranteed, and the compressors are always operated in a power frequency state.
As the cold quantity demand of the data machine room continuously increases, the precision air conditioner acquires the temperature of the machine room in real time through a temperature sensor to obtain the current return air temperature T1 measured each time;
when four main compressors in four precision air conditioning units normally operate and are started, the starting flows of the four auxiliary compressors are as follows:
1) when the T1 (the current return air temperature is adjustable and can be reset) is higher than 26 ℃, the duration time1 of the T1 is higher than 1min (adjustable), the first slave compressor is started; at the moment, the air supply temperature of the first precision air conditioner is adjusted to be T2 ═ f (T1); if T1 is less than 25 ℃ and the first slave compressor is continuously operated for a time period of 2>30min, the first slave compressor is turned off.
2) After the first slave compressor is started, when T1 is higher than 28 ℃ and the duration time1 is longer than 1min, the second slave compressor is started; at the moment, the air supply temperature of the second precision air conditioner is adjusted to be T2 ═ f (T1); when T1<27 ℃, and the second slave compressor duration time2>30min, the second slave compressor is turned off.
3) After the second slave compressor is started, when T1 is more than 30 ℃, and the duration time1 is more than 1min, the third slave compressor is started; at the moment, the air supply temperature of the third precision air conditioner is adjusted to be T2 ═ f (T1); when T1<29 ℃ and the third slave compressor has a time duration of 2>30min, the third slave compressor is turned off.
4) After the third slave compressor is started, when T1 is higher than 32 ℃, and the duration time1 is longer than 1min, the fourth slave compressor is started; at the moment, the air supply temperature of the fourth precision air conditioner is adjusted to be T2 ═ f (T1); when T1<31 ℃ and the fourth slave compressor duration time2>30min, the fourth slave compressor is turned off.
Wherein, the formula corresponding to T2 ═ f (T1) is as follows:
Tsp＝Tspmid-a(Tspmax-Tspmin)(Tr-Trsp)
in this example, T2 is equivalent to TspT1 is equivalent to Tr。
When T1 is detected to be higher than 34 ℃ and the duration time1 is longer than 1min, the main control board controls the alarm to send out an alarm prompt.
Further, because each compressor is operated in a power frequency state in the invention, in order to avoid that when power is cut and power is supplied again, the four main compressors are started simultaneously to impact the power grid, the main control board can start the four main compressors step by step, for example: after each main compressor is started for a period of time, the next main compressor is started to ensure the normal operation of the precision air conditioner.

Of course, the specific installation position of the temperature sensor may be determined according to actual situations, and this embodiment is not limited thereto. In addition, in the present embodiment, a temperature sensor for measuring the temperature of the air supply may be provided in the static pressure tank connected to the precision air conditioner.
