Description
Technical Field
The invention relates to the field of air conditioning equipment, in particular to an air conditioner control method, device, equipment and storage medium.
Background
The temperature control principle of the variable frequency air conditioner is as follows: the variable frequency air conditioner can automatically adjust the running frequency of the compressor according to the change of the cold (heat) load of the room; generally, when a user just starts the machine, the load is large, the difference between the indoor temperature and the set temperature is large, and the compressor runs at a high frequency; along with the indoor temperature is closer to the set temperature, the frequency can be gradually reduced to adapt to the change of the load, and the purpose of running without stopping the machine is achieved through the change of the frequency, so that the discomfort caused by the severe change of the room temperature due to frequent starting and stopping of the machine is avoided.
In the case of a low load during operation in the cooling mode: if the temperature set by the user is higher, and meanwhile, the outdoor environment temperature is close to or even lower than the set temperature, especially under the condition that the air conditioner has relatively large matching number and small using environment area, the frequency conversion air conditioner runs to the lower frequency limit, but the output cold quantity is still larger than the room cold quantity requirement, and the room temperature can continue to drop until the temperature is stopped; after the machine is shut down, the machine can be restarted only after a long time due to the fact that the heat load of the room is small, and in the repeated starting and shutting processes, the temperature of the room is suddenly cold and hot, so that a user feels very uncomfortable.
At present, in order to solve the problem of repeated start and stop of an air conditioner, the conventional means is to reduce the lower limit of the running frequency of a variable frequency compressor or make the variable frequency compressor not easily reach the stop condition through refrigeration inner ring temperature compensation; however, the lower limit of the operating frequency of the compressor is reduced and cannot be reduced to a low level due to the influence of factors such as the driving reliability of the compressor, pipeline vibration, system oil return and the like; the method of compensating for the temperature reached by the delayed air conditioner through the inner ring temperature can cause the problem that the room temperature is much lower than the temperature set by the user, and the user feels too cold.
