[0002] Existing group control methods for air conditioners in computer rooms typically network all the air conditioners within a computer room for centralized control. Common group control features include anti-competition (preventing all air conditioners in the room from operating simultaneously for cooling, heating, humidification, or dehumidification), scheduled patrol (ensuring that all air conditioners in the room operate at the same time), fault auto-restart (automatically restarting other air conditioners in standby mode if one air conditioner fails), and fault redundancy (initiating the sequential restart of other air conditioners in the network if the temperature of one air conditioner in the network remains above a certain threshold).

[0047] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0048] Reference Figure 1 , Figure 1 This is one of the flow charts of the air conditioner group control method in the embodiment of the present application. The air conditioner group control method provided in the embodiment of the present application may include:

[0049] Step 100, determining the output cooling capacity of each air conditioner based on the supply and return air data of each air conditioner;

[0050] In one embodiment, the air conditioner group control method provided in the embodiment of the present application may further include:

[0051] Step 110: Determine the inlet air enthalpy value h of the Yth air conditioner based on the supply air temperature and humidity and the return air temperature and humidity of the Yth air conditioner. y-1 and return air enthalpy h y-2 ;

[0052] Step 120: Obtain the air volume q of the Yth air conditioner y and supply air density ρ y ;

[0053] Step 130, based on formula Q y =(h y-2 -h y-1 )×q y ×ρ y , determine the output cooling capacity Q of the Yth air conditioner y .

[0054] Specifically, the present application provides an air conditioning group control method applied to a computer room system. The computer room system mainly includes M air conditioners and N server cabinets, where M and N are both positive integers greater than 1. The computer room system also includes temperature and humidity sensors (used to obtain data such as supply air temperature and humidity and return air temperature and humidity) and some infrastructure.

[0055] Based on the supply air temperature and humidity and return air temperature and humidity of the Yth air conditioner obtained by the sensor, determine the inlet air enthalpy value h of the Yth air conditioner y-1 and return air enthalpy h y-2 , and the air volume q detected by the Yth air conditioner y The air density ρ of the Yth air conditioner in the air supply can be obtained by the air supply temperature and humidity sensor y The cooling capacity Q of the Yth air conditioner can be determined by the following formula 1: y .

[0056] Q y =(h y-2 -h y-1 )×q y ×ρ y ;(1)

[0057] Step 200: while sequentially increasing the cooling capacity of each of the air conditioners, obtain N sets, each of which contains the average inlet air temperature change rates of M server cabinets;

[0058] Specifically, after each air conditioner is running stably (for example, the cooling demand of the air conditioner is considered to be running stably if the change rate is within 5% within five minutes), while keeping other air conditioners unchanged, the cooling capacity of each air conditioner is increased in turn (for example, by 30% of the cooling demand of the air conditioner), and the average inlet air temperature change rate of N cabinets can be obtained. For example, while keeping other air conditioners unchanged, the cooling capacity of the first air conditioner is increased, and the sequence of the average inlet air temperature change rate of N cabinets {K11, K12, ..., K1 X ,...,K1 N}; Increase the cooling capacity of the Yth air conditioner and obtain the sequence of the average inlet air temperature change rate of N cabinets {KY1,KY2,...,KY X ,...,KY N}; By analogy, we can know that by increasing the cooling capacity of the Mth air conditioner, we can get a sequence of the average inlet air temperature change rate of N cabinets {KM1, KM2, ..., KM X ,...,KM N As shown in Table 1 below.

[0060] Table 1

[0061] After the cooling capacity of all air conditioners is increased, N sets are obtained. Each server cabinet corresponds to a set, and each set contains the average inlet air temperature change rate values ​​of M server cabinets. As shown in Table 1, the set corresponding to the first server cabinet is {K11, K21, ..., KY1, ..., KM1}; the set corresponding to the Xth server cabinet is {K1 X ,K2 X ,...,KY X ,...,KM X}; It can be seen that the set corresponding to the Nth server cabinet is {K1 N ,K2 N ,...,KY N ,...,KM N}.

[0062] Step 300 , sorting the set corresponding to each server cabinet according to the numerical value, and determining the Yth air conditioner corresponding to the maximum average inlet air temperature change rate value of the Xth server cabinet, where 1≤X≤N, 1≤Y≤M;

[0063] Step 400: Add the Xth server cabinet to the candidate area of ​​the Yth air conditioner until all server cabinets are added;

[0064] Specifically, the average inlet air temperature change rate of the Xth cabinet has M values. These M values ​​are sorted by size. If the largest value is KY X , then put the Xth cabinet into the candidate area of ​​the Yth air conditioner. Similarly, the candidate area of ​​each air conditioner can be obtained, and each candidate area of ​​the air conditioner may contain one server cabinet, multiple server cabinets, or even no server cabinets.

[0065] Step 500: determining a management cabinet range of each air conditioner based on the input power of the server cabinets in the selected area of ​​each air conditioner and the rated cooling capacity of each air conditioner;

[0067] Table 2

[0068] Using the above method, each server cabinet is placed in the candidate zone of each air conditioner, ensuring that no server cabinet is placed in the candidate zones of multiple air conditioners simultaneously. As shown in Table 2, the candidate zone for the first air conditioner includes server cabinets 1, 3, 10, and 14, for a total of four server cabinets; the candidate zone for the second air conditioner includes server cabinets 2, 4, 7, and 13, for a total of four server cabinets; the candidate zone for the Yth air conditioner includes server cabinets 5, 6, 9, 11, 16, and N, for a total of six server cabinets; and the candidate zone for the Mth air conditioner includes server cabinets 8, 12, and 15, for a total of three server cabinets. The data in Table 2 represents the input power of each server cabinet.

[0069] Taking the candidate area of ​​the Yth air conditioner as an example, the determination of the management cabinet range of the Yth air conditioner is described.

[0070] First, obtain the rated cooling capacity of the Yth air conditioner (hereinafter referred to as Q1). Second, sort the input power of all server cabinets in the candidate area of ​​the Yth air conditioner in descending order. If the sorting result is PY6, PY 11 、PY N 、PY 16 , PY5 and PY9, that is, in the candidate area of ​​the Yth air conditioner, the input power of the 6th server cabinet is the largest and the input power of the 9th server cabinet is the smallest.

[0071] If PY6+PY 11 +PY N +PY 16≤Q1, and PY6+PY 11 +PY N +PY 16 If +PY5≥Q1 holds, the managed cabinet range of the Yth air conditioner includes the 6th, 11th, Nth, and 16th server cabinets. However, the 5th and 9th server cabinets are not included in the managed cabinet range of the Yth air conditioner.

[0072] Step 600: Control the cooling capacity of each of the air conditioners according to the total input power corresponding to each of the management cabinets.

[0073] Specifically, after determining the management cabinet range of each air conditioner according to the above solution, determine the sum of the input power of all server cabinets within the management cabinet range of each air conditioner, that is, determine the total input power P corresponding to each management cabinet range. A .

[0074] According to the formula Q y =kP A Control the output cooling capacity of the air conditioner, where Q y is the output cooling capacity of the air conditioner, k is the cooling capacity output correction coefficient, and k can be adjusted according to actual conditions.

[0075] This embodiment considers various factors affecting air conditioner operation, such as the air conditioner's supply and return air data, the average air inlet temperature and input power of the server cabinet, and the placement of the cabinet and air conditioner (i.e., the management cabinet range of each air conditioner). The average inlet temperature change rate of the cabinet is used as an evaluation indicator to adjust the corresponding position of the air conditioner and the cabinet. This makes the cooling adjustment of the air conditioner based on the input power control of the cabinet more precise. Under precise group control, the energy consumption of the air conditioner is also effectively controlled.

[0076] Reference Figure 2 , Figure 2 This is a second flow chart of the air conditioner group control method in the embodiment of the present application. In one embodiment, the air conditioner group control method provided in the embodiment of the present application may further include:

[0077] Step 210: While increasing the cooling capacity of the first air conditioner, obtain N sets, each of which contains an average inlet air temperature change rate of the server cabinet;

[0078] Step 220: While increasing the cooling capacity of the Mth air conditioner, obtain N sets, each of which contains the average inlet air temperature change rate of the M server cabinets.

[0079] Specifically, as shown in Table 1, while keeping the air conditioners 2 through M unchanged, the cooling capacity of the first air conditioner is increased to obtain the first average inlet air temperature change rate for N cabinets. The cooling capacity of each air conditioner is increased sequentially. While keeping the air conditioners 1 through M-1 unchanged, the cooling capacity of the Mth air conditioner is increased to obtain the Mth average inlet air temperature change rate for N cabinets. Ultimately, N sets are obtained, each containing the average inlet air temperature change rates for M server cabinets.

[0080] This embodiment uses a variable control method to obtain the average inlet air temperature change rate of N groups of server cabinets, which is used to adjust the evaluation criteria for the position relationship between the air conditioner and the server cabinet. Based on this precise evaluation criteria, accurate group control can be achieved.

[0081] In one embodiment, the air conditioner group control method provided in the embodiment of the present application may further include:

[0082] Step 510: Sort the input powers of the server cabinets in the Yth air conditioner's selected area according to their numerical values ​​to obtain a sequence {PY i ,PY i-1 ,...,PY1}, where PY i is the input power of the i-th server cabinet in the candidate area of ​​the Y-th air conditioner, PY i >PY i-1 ;

[0083] Step 520: Determine the management cabinet range of the Yth air conditioner as the sequence {PY i ,PY i-1 ,...,PY n} corresponding server cabinet, where n≥1, PY i +PY i-1 +...+PY n ≤Q1,PY i +PY i-1 +...+PY n +PY n-1 ≥Q1, where Q1 is the rated cooling capacity of the Yth air conditioner.

[0084] Specifically, as can be seen from the content of step 500 above, if the input powers of all server cabinets in the candidate area of ​​the Yth air conditioner are sorted, the sorting results are PY6, PY 11 、PY N 、PY 16 , PY5 and PY9, wherein PY6 corresponds to PY in the embodiment i , PY 11 Corresponding to PY in the embodiment i-1 , PY9 corresponds to PY1 in the embodiment.

[0085] Q1 is the rated cooling capacity of the Yth air conditioner. In this case, if the following conditions PY6+PY 11 +PY N +PY 16 ≤Q1, and PY6+PY 11 +PY N +PY 16 +PY5≥Q1, then PY 16 Corresponding to PY in the embodiment n , PY5 corresponds to PY in the embodiment n-1 The following describes how to handle server cabinets that are not selected by the management cabinet range of the Yth air conditioner.

[0086] This embodiment determines the management cabinet range of each air conditioner through the relationship between the rated cooling capacity of the air conditioner and the input power of the server cabinet, which can achieve more accurate air conditioner group control.

[0087] In one embodiment, the air conditioner group control method provided in the embodiment of the present application may further include:

[0088] Step 10: When n is greater than 1, determine a target cabinet, where the target cabinet is a server cabinet that is not within the management cabinet range of the Yth air conditioner;

[0089] Step 20: Determine the Zth air conditioner based on the set corresponding to the target cabinet, and add the target cabinet to the candidate area of ​​the Zth air conditioner;

[0090] Step 30: Sort the input powers of the server cabinets in the selected area of ​​the Zth air conditioner according to the numerical values ​​to obtain a sequence {PZ i ,PZ i-1 ,...,PZ1}, where PZ i is the input power of the i-th server cabinet in the candidate area of ​​the Z-th air conditioner, PZ i >PZ i-1 ;

[0091] Step 40: Determine the management cabinet range of the Zth air conditioner as the sequence {PZ i ,PZ i-1 ,...,PZ i ,PY x} corresponding server cabinet, where PZ i +PZ i-1 +...+PZ1+PY x ≤Q2,PY x is the input power of the target cabinet, PY x is the sequence {PY n-1 ,PYn-2 ,...,PY1}, Q2 is the rated cooling capacity of the Zth air conditioner.

[0092] In one embodiment, the air conditioner group control method provided in the embodiment of the present application may further include:

[0093] Step 21: Delete the maximum average inlet air temperature change rate value in the set corresponding to the target cabinet, and determine a second average inlet air temperature change rate value in the set corresponding to the target cabinet, where the second average inlet air temperature change rate value in the set corresponding to the target cabinet is only less than the deleted maximum average inlet air temperature change rate value.

[0094] Step 22: Determine that the air conditioner corresponding to the second average inlet air temperature change rate value is the Zth air conditioner.

[0095] Specifically, taking the above-mentioned Yth air conditioner as an example, n greater than 1 indicates that there is at least one server cabinet in the selected area of ​​the Yth air conditioner that is not selected by the management cabinet range of the Yth air conditioner. In this embodiment, it is called the target cabinet, that is, the target cabinet is a server cabinet that is not within the management cabinet range of the Yth air conditioner.

[0096] The process of determining the Zth air conditioner based on the set corresponding to the target cabinet and adding the target cabinet to the candidate area of ​​the Zth air conditioner is as follows:

[0097] Taking the target cabinet corresponding to PY5 (i.e., the 5th server cabinet) as an example, in the set {K15, K25, ..., KY5, ..., KM5} corresponding to the 5th server cabinet, the air conditioner corresponding to the maximum average inlet air temperature change rate value KY5 is the Yth air conditioner. KY5 is deleted to obtain the set {..., KZ5, ...}. The maximum average inlet air temperature change rate value in the set {..., KZ5, ...} is KZ5 (i.e., the second average inlet air temperature change rate value in this embodiment), where KZ5 in the set {K15, K25, ..., KY5, ..., KM5} is only smaller than KY5, and Z can be any value from 1 to M except Y, but the following conditions need to be met.

[0098] Take Z as an example. The candidate area for the second air conditioner includes server cabinets 2, 4, 7, and 13, a total of four server cabinets. The rated cooling capacity of the second air conditioner is Q2. The input power of the server cabinets in the candidate area for the second air conditioner is sorted by value. If the sorting result is P24, P27, P22, and P2 13 , the sequence {P24,P27,...,P2 13} and the sequence {PZ i ,PZ i-1,...,PZ1} corresponds. If P24+P27+P22+P2 13 If +PY5≤Q2 holds, the fifth server cabinet is added to the management cabinet range of the second air conditioner.

[0099] The above solution only illustrates one case. It can be seen that after deleting KY5, you can return to the above step 300 to re-sort the set corresponding to each server cabinet, and then execute other subsequent steps until all server cabinets are added to the management cabinet range.

[0100] This embodiment processes the server cabinets that are not selected by the management cabinet range in a reasonable manner.

[0101] In one embodiment, the air conditioner group control method provided in the embodiment of the present application may further include:

[0102] In step 50, when the management cabinet range of each air conditioner is determined and there is a server cabinet that is not within the management cabinet range of any air conditioner, the rated cooling capacity of any air conditioner, or the rated cooling capacity of multiple air conditioners, or the rated cooling capacity of all air conditioners is adjusted.

[0103] Specifically, if, after following the above solution, there are still server cabinets that do not belong to the management cabinet range of any air conditioner, it means that the rated cooling capacity of the existing air conditioner cannot meet the input power of all server cabinets. In this case, the rated cooling capacity of the air conditioner can be adjusted (increased) based on the input power of the server cabinets that do not belong to the management cabinet range of any air conditioner. The adjustment method can be to adjust any air conditioner individually (prioritizing the air conditioner with a rated cooling capacity much greater than the total input power of all cabinets within its management cabinet range), or to adjust multiple air conditioners at the same time, or to adjust all air conditioners at the same time. The adjustment method can be selected based on the implementation cost.

[0104] This embodiment addresses the problem of server cabinets that do not belong to the management cabinet range of any air conditioner by adjusting the rated cooling capacity of the air conditioner.
