calculating the condensation point temperature according to the detection temperature of the defrosting sensor and the environment temperature of the outdoor unit;
and if the condensation point temperature meets a first judgment condition, determining that the air conditioner is in a defrosting mode.
3. The air conditioner control method according to claim 2, wherein if the dew point temperature satisfies a first determination condition, it is determined that the air conditioner is in a defrosting mode, and specifically includes:
determining the temperature range of the condensation point temperature;
and determining to enter a defrosting mode according to the temperature range, and matching preset defrosting operation interval time.
4. The air conditioner control method according to claim 1, wherein in a case where it is determined that the air conditioner has finished the defrosting mode, generating an operation command specifically includes:
the compressor stops rotating within a preset time period, and the outdoor fan operates;
after the preset time period is finished, the compressor is started, the outdoor fan stops rotating, the indoor electric heating is started, and the rotating speed of the indoor fan is adjusted according to the temperature of the evaporator.
5. The air conditioner control method according to claim 4, wherein after the preset time period is over, the compressor is started, the outdoor fan is stopped, and the indoor fan adjusts the rotation speed according to the evaporator temperature, specifically comprising:
when the temperature of the evaporator is lower than a first temperature threshold value, the indoor fan operates at the minimum rotating speed;
and when the temperature of the evaporator is greater than the second temperature threshold value, the indoor fan operates at the maximum rotating speed.
6. The air conditioner control method according to claim 1, wherein the working instruction is used for controlling the air conditioner to shift to a normal working mode, and specifically comprises:
acquiring the temperature and the maintaining time of the outdoor heat exchanger;
and after the temperature and the maintaining time of the outdoor heat exchanger meeting the second judgment condition are reached, the defrosting mode is quitted, and the normal working mode is switched to.
7. An air conditioning control system, the system comprising:
the defrosting operation module is used for generating a temperature control instruction under the condition that the air conditioner is determined to be in a defrosting mode, wherein the temperature control instruction is used for starting indoor electric auxiliary heating and regulating the rotating speed of an indoor fan;
and the defrosting ending module is used for generating a working instruction under the condition of determining that the air conditioner ends the defrosting mode, and the working instruction is used for controlling the air conditioner to be switched into a normal working mode.
8. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein the processor implements an air conditioning control method according to any one of claims 1 to 6 when executing the program.
9. A non-transitory computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements an air conditioning control method according to any one of claims 1 to 6.
10. A computer program product comprising a computer program, wherein the computer program, when executed by a processor, implements an air conditioning control method according to any one of claims 1 to 6.
