Fig. 2 is a schematic flow chart of an air conditioner control method provided in an embodiment of the present application, where the method of the embodiment may be executed by a controller of an air conditioner, the air conditioner is disposed in a machine room, and the air conditioner includes a plurality of compressors. As shown in fig. 2, the method of the present embodiment may include:
s201: and acquiring a first temperature value acquired by the temperature sensor, wherein the first temperature value is the temperature value in the machine room.

In this embodiment, after the first temperature value is obtained, the operation mode of the air conditioner may be determined according to the relationship between the obtained first temperature value and the first preset temperature set in advance.
Optionally, if the obtained first temperature value is higher than the first preset temperature, the first operation mode may be started. The first operation mode is that a plurality of compressors in the air conditioner are all in an on state.
S203: if the first temperature value is lower than the first preset temperature and higher than the second preset temperature, judging whether the capacities of a plurality of compressors in the air conditioner are the same or not.
In this embodiment, if the first temperature value is lower than the preset first preset temperature and higher than the preset second preset temperature, the second operation mode may be started. The second operation mode is that one target compressor in the air conditioner is in an on state. In addition, the second preset temperature is lower than the first preset temperature.
S204: if the capacities of the plurality of compressors in the air conditioner are different, when the second operation mode is started, the target compressor with the minimum capacity in the air conditioner is started.
Furthermore, the method may further comprise:
and if the capacities of the plurality of compressors in the air conditioner are the same, starting any target compressor in the air conditioner when the second operation mode is started, wherein the target compressor is a variable frequency compressor.

By setting a plurality of working modes for the air conditioner in the machine room in advance, and when the second working mode is started, the mode of starting the target compressor with the minimum capacity in the air conditioner can be automatically switched to the matched working mode according to the temperature in the machine room, so that the air conditioner in the machine room is prevented from being in a high-power-consumption working state all the time, and when only one compressor is started, only the target compressor with the minimum capacity is started, so that the energy consumption is reduced, and meanwhile, the frequent switching of the compressors is avoided, and the failure rate of the air conditioner is further reduced.

The temperature difference threshold may be set according to the actual application scenario, and may be, for example, any value between 3 and 5 degrees. Further, the multi-fan assembly may be an existing component, and illustratively, may be a combination of multiple fans.

Specifically, when the pre-set pressure range and the maximum working current corresponding to different operation modes are different when the pre-set pressure range and the maximum working current corresponding to the current operation mode are switched to the pre-alarm mode, the pre-set pressure range and the maximum working current corresponding to the current operation mode can be determined first, and then whether the pre-set pressure range and the maximum working current corresponding to the current operation mode need to be switched to the pre-alarm mode or not can be determined according to the pre-set pressure range and the maximum working current corresponding to the current operation mode. Alternatively, the pressure monitor can be used for monitoring the pressure of the condenser and the suction and discharge pressure of the compressor, and the current monitor can also be used for monitoring the current values input by the fan and the compressor motor. In addition, the compressor is provided with a low-pressure protection mechanism and a high-pressure protection mechanism, and the low-pressure protection set value and the high-pressure protection set value of the compressor are wider than those of the condensing pressure, so that the condensing pressure can be monitored and controlled in a linkage way with the system.

If the number of the fans is smaller than the preset number, an early warning mechanism can be entered, and the intelligent control module (in the controller) is used for adjusting the multiple groups of fans. When the early warning cannot be eliminated, whether the early warning mode needs to be switched to can be determined through the condensation pressure and the maximum working current (the working current of the external fan and the working current of the compressor). If the condensing pressure of the condenser is not in the preset pressure range or the current values of the compressor and the multi-fan assembly are higher than the maximum working current, switching to an early warning mode.
In conclusion, through setting up multiple working modes, judging and energy-saving regulation are carried out through the intelligent control module, and meanwhile, the system is embedded with a safety protection algorithm and an operation mechanism, so that the energy efficiency and the safety of the system are improved.
