and when the temperature of the indoor unit pipeline is higher than the preset temperature, controlling the air conditioner to exit the cold air prevention mode and normally run.
5. The air conditioner operation control method as claimed in claim 1, wherein before the step of receiving a first operating frequency of the compressor at a first preset time before defrosting, the air conditioner operation control method further comprises:
judging whether the running time of the air conditioner is greater than a second preset time or not;
if yes, executing the step of receiving the first operating frequency of the compressor at the first preset time before defrosting when a signal of defrosting end is received;
if not, controlling the air conditioner to continue to operate until the operation time of the air conditioner is greater than the second preset time.
6. The operation control method of an air conditioner according to claim 1, wherein the step of receiving the first operating frequency of the compressor for a first preset time before defrosting comprises:
receiving a plurality of instantaneous operating frequencies of the compressor within a first preset time before defrosting;
setting a maximum value of the plurality of instantaneous operating frequencies to the first operating frequency.
7. The operation control method of the air conditioner according to claim 1, wherein the first preset time is longer than 3min, and the preset operation frequency is 70Hz to 110 Hz.
8. An operation control device of an air conditioner, comprising:
the defrosting control device comprises a receiving module, a defrosting control module and a control module, wherein the receiving module is used for receiving a first operating frequency of a compressor in a first preset time before defrosting;
the setting module is used for setting the actual operating frequency of the compressor after defrosting is finished according to the first operating frequency and a preset operating frequency, wherein the actual operating frequency is greater than or equal to the first operating frequency; the setting module is further configured to determine whether the first operating frequency is greater than or equal to a preset operating frequency, set the first operating frequency as the actual operating frequency if the determination result is yes, and set a second operating frequency as the actual operating frequency if the determination result is no, where the second operating frequency is greater than the first operating frequency;
and the control module is used for controlling the air conditioner to operate a heating mode after defrosting is finished and operating the compressor at the actual operating frequency.
9. An air conditioner comprising a controller for executing computer instructions and implementing the air conditioner operation control method according to any one of claims 1 to 7.
