The following description of the present application is given by taking several embodiments as examples, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flow chart of a method for controlling an air conditioner in a machine room according to an embodiment of the present application, where an execution body of the embodiment may be a processor in the embodiment shown in fig. 1, and as shown in fig. 2, the method may include:
S201: and judging whether the air conditioner KTi is in a shutdown state or whether the valve opening of the air conditioner KTi is zero, wherein the air conditioner KTi is any one of the main air conditioners corresponding to the target cold channels of the target machine room, i=1, … …, n and n are equal to the number of the main air conditioners corresponding to the target cold channels, the target cold channels are any one of the cold channels of the target machine room, and the main air conditioner corresponding to each cold channel adjacent to the target cold channel is a standby air conditioner of the target cold channel.
Here, the above-mentioned processor may first determine whether each main air conditioner corresponding to each cold channel of the target machine room is in an automatic control state, and if the air conditioner KTi is not in the automatic control state, execute the above-mentioned step of determining whether the air conditioner KTi is in a shutdown state or whether the valve opening of the air conditioner KTi is zero; if the air conditioner KTi is in an automatic control state, the valve opening of the air conditioner KTi can be determined based on a calculation formula of the preset refrigerating capacity and the valve opening, so that the valve opening of the air conditioner KTi is adjusted based on the valve opening, and application requirements under different application scenes are met.
Exemplary, as shown in fig. 3, a cold aisle schematic is provided in an embodiment of the present application. The number relation between the main air conditioner K and the cold channels U in one machine room is shown as u=2k, and the redundancy is 1.KT (1), KT (2) are cold passageway U 12 main air conditioner, KT (3), KT (4) are U 12 reserve air conditioner, KT (3), KT (4) are cold passageway U 34 main air conditioner, KT (1), KT (2) are U 34 reserve air conditioner.
Taking the target cold channel as U 12 as an example, the air conditioner KTi may be any one of the main air conditioners corresponding to U 12, for example, KT (1) or KT (2).
In addition, before judging whether the air conditioner KTi is in a shutdown state or whether the valve opening of the air conditioner KTi is zero, the processor may determine the power of the header cabinet of the target cold channel according to the power of each header cabinet corresponding to the target cold channel, and determine the power of the header cabinet of the corresponding cold channel adjacent to the target cold channel according to the power of each header cabinet corresponding to each cold channel adjacent to the target cold channel, so that the subsequent processing may be directly performed based on the determined data. For example, taking cold aisle U 12 in fig. 3 as an example, the column header cabinet power of cold aisle U 12 is equal to a preset multiple, e.g., 1.1 times, of the sum of the power of column header cabinet a and the power of column header cabinet B.
Any one of the main air conditioners corresponding to the target cold channels of the target machine room may be understood as any one of the main air conditioners corresponding to the target cold channels of the target machine room.
S202: if the air conditioner KTi is in a starting state and the valve opening of the air conditioner KTi is not zero, determining the first total refrigerating capacity of each main air conditioner corresponding to the target cold channel according to the refrigerating capacity of the air conditioner KTi and the preset rated refrigerating capacity of the air conditioner, and judging whether the power of the cabinet at the head of the target cold channel is larger than the first total refrigerating capacity of each main air conditioner corresponding to the target cold channel.
Here, the processor may set the cooling capacities of the remaining main air conditioners except the air conditioner KTi corresponding to the target cold path to the preset rated cooling capacity of the air conditioner, so that the sum of the cooling capacities of the air conditioner KTi and the cooling capacities of the remaining main air conditioners is used as the first total cooling capacity of each main air conditioner corresponding to the target cold path, the column header cabinet power of the target cold path is compared with the first total cooling capacity of each main air conditioner corresponding to the target cold path, and a required cooling capacity of the air conditioner is determined according to a comparison result, so that the corresponding air conditioner is regulated and controlled based on the required cooling capacity of the air conditioner.
For example, before determining the first total cooling capacity of each main air conditioner corresponding to the target cooling channel according to the cooling capacity of the air conditioner KTi and the preset rated cooling capacity of the air conditioner, the processor may further obtain a valve opening of the air conditioner KTi, and further determine the cooling capacity of the air conditioner KTi according to the valve opening of the air conditioner KTi and a calculation formula of the preset cooling capacity and the valve opening, where the calculation formula of the preset cooling capacity and the valve opening is determined according to a first relational formula and a second relational formula, and the first relational formula is: q/q max = R (L-1), where R represents the maximum to minimum water flow ratio of the valve control of the air conditioner, R = q max/qmin, q represents the water flow of the air conditioner, q max represents the maximum water flow of the valve control of the air conditioner, q min represents the minimum water flow of the valve control of the air conditioner, and L represents the valve opening of the air conditioner; the second relation is: q 1＝QKT R (L-1), wherein Q 1 represents the power of the air conditioner and Q KT represents the rated refrigerating capacity of the air conditioner.
Wherein, R and q max can be calculated by rated parameters of the air conditioner.
S203: and if the power of the header cabinet of the target cold channel is larger than the first total refrigerating capacity of each main air conditioner corresponding to the target cold channel, regulating the valve opening of the rest main air conditioners except the air conditioner KTi corresponding to the target cold channel to be a preset rated opening, and determining the first required air conditioner refrigerating capacity according to the power of the header cabinet of each cold channel adjacent to the target cold channel, the power of the header cabinet of the target cold channel and the first total refrigerating capacity of each main air conditioner corresponding to the target cold channel.
