Through the priority selection of loading and unloading according to the health degree of the air conditioner, the energy consumption increase caused by low comprehensive operation efficiency due to fault operation of the air conditioner is reduced to the maximum extent, the air conditioner combination participating in operation is guaranteed to be the most stable, the operation reliability is guaranteed, and the comprehensive service life of the air conditioner is prolonged to the maximum extent.
Step S1: collecting environmental parameters of a set area in the transformer substation in real time, judging whether the environmental parameters are in a preset range, and if so, executing step S5; if not, go to step S2;
in the embodiment, in order to ensure that the temperature and humidity conditions of different areas in the transformer substation are consistent, a plurality of air conditioners are uniformly distributed in the transformer substation, a plurality of uniformly distributed detection devices are arranged in the transformer substation, and the air conditioners and the detection devices can be in one-to-one correspondence so as to improve the accuracy of collecting environmental parameters in the transformer substation; in this embodiment, the detection device can be set as a temperature and humidity sensor, and the temperature and humidity condition in the substation is detected in real time through the detection device.
In this embodiment, the inside of the whole substation may be divided into a plurality of local areas, the set area may be defined as the whole internal space of the substation, or a certain local area in the substation may be designated as the set area, and then the detection device in the set area is controlled to start, so that the environmental parameters of the local area or the whole area may be detected in a targeted manner, thereby implementing the air-conditioning linkage control of the local area or the whole area.

If the fluorine is absent, the refrigeration is carried out but the temperature cannot be reduced, and the running state completely deviates from the standard running working condition, the fault level fd is also 100 percent; if no fluorine exists, the refrigerant can be cooled, but has a certain cooling effect or the operation state is slightly deviated from the standard operation working condition, and the cooling effect is 30% or 50%, and the specific percentage is analyzed according to the actual condition.

The number of the air conditioners with the highest air conditioner state grade can be one or more, if the current environmental parameters exceed the preset range in a small range, the air conditioner with the highest air conditioner state grade can be controlled to be started, if a plurality of air conditioners with the same air conditioner state grade appear in the period, the detection equipment corresponding to the air conditioners with the same air conditioner state grade can be controlled to detect the current temperature and humidity in real time, and the air conditioner corresponding to the detection equipment with the highest detected temperature and humidity value is controlled to be started preferentially.
If the current environmental parameters greatly exceed the preset range, the front air conditioners in the health degree sequencing can be started simultaneously, and if a plurality of air conditioners with the same air conditioner state grade appear in the period, the air conditioners are controlled to be started and operated synchronously, so that the environmental parameters in the transformer substation are adjusted quickly.
Step S4: if the whole temperature and humidity in the transformer substation are low, acquiring the current operation state of each air conditioner in the transformer substation, selecting the air conditioner with the lowest air conditioner state grade from the air conditioners in the opened state, and controlling the air conditioners to be turned off and unloaded; thereafter, it jumps to and executes step S1;

Step S5: when the linkage control in the transformer substation is finished and the environmental parameters are always maintained within the preset range, the current operation state of each air conditioner in the set area can be kept, and the temperature and the humidity of the transformer substation are maintained within a reasonable range.
The application range of the invention is not limited to the interior of a transformer substation, and the air conditioner linkage control method can be used in application places such as machine rooms, meeting rooms and the like which need linkage of a plurality of air conditioners.
