A part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Provided in an embodiment of the present invention is a kind of snow removing control method based on air-conditioner outdoor unit as shown in Figure 1, air-conditioning
The lateral surface of outdoor condenser 1 is equipped with and sweeps away snow mechanism 2, as shown in Fig. 2, snow removing control method the following steps are included:
S1, air-conditioning open heating mode；
S2, mechanism of sweeping away snow enter standby mode；
S3 detects operation of air conditioner power and electric current；Specifically, in the present embodiment operation of air conditioner power and electric current detection frequency
Rate is preferably that every 2~5min detection is primary；
S4 judges run whether power is less than setting performance number and electric current is lower than setting electric current value, if operation power is less than
Setting performance number and electric current are lower than setting electric current value and then follow the steps S5；Otherwise, step S3 is executed；Specifically, in the present embodiment
When air-conditioning number is 1, setting performance number is preferably 1631~1630w, and setting electric current is preferably 6.5~7.1A.
S5 controls mechanism 2 of sweeping away snow and clears up the lateral surface of condenser 1；S2 is returned to step after the completion of cleaning.
The snow removing control method of air-conditioner outdoor unit provided in an embodiment of the present invention is after air-conditioning enters heating mode according to sky
The operation power and current control of tune mechanism 2 of sweeping away snow clear up the lateral surface of condenser 1, remove 1 lateral surface of condenser
Accumulated snow or frost avoid the accumulated snow of 1 lateral surface of condenser or frost from influencing the heat exchange efficiency of condenser 1, to ensure that the system of air-conditioning
Thermal effect.When 1 surface accumulated snow of condenser is serious, operation of air conditioner power and electric current can all be reduced, and be transported according to the air-conditioning detected
Row power and current control are swept away snow the work of mechanism 2, can be removed the accumulated snow of 1 outer surface of condenser in time, be avoided simultaneously
