Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
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 mechanism 2 of sweeping away snow, as shown in Fig. 2, the snow removing control method of air-conditioner outdoor unit, including with
Lower step:
S1, air-conditioning open heating mode；
S2, mechanism of sweeping away snow enter standby mode；
S3 starts calculating air-conditioning and is in heating mode duration；
S4, judges whether the heating mode duration is greater than setting operating time, sets if the heating mode duration is greater than
Determine operating time and then follow the steps S5, otherwise continues to execute step S4；Preferably, operating time is set as 30 in the present embodiment
~60min.Specifically, when outdoor environment temperature is -7 DEG C, setting operating time is set as 45min, can be according to different
Outdoor environment temperature sets different operating times, realizes intelligentized control method；
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.Tool
Body, mechanism of sweeping away snow in the present embodiment 2 starts calculating air-conditioning to the lateral surface cleaning of condenser 1 after the completion and holds in heating mode
Start air-conditioner outdoor unit defrost pattern while the continuous time, further removes the frost or accumulated snow on 1 surface of condenser, prevent from tying
Ice guarantees good heat transfer effect.
When the snow removing control method air-conditioning of air-conditioner outdoor unit provided in an embodiment of the present invention enters one section of heating mode heating
Between post-condenser 1 lateral surface can accumulated snow or frost accumulated, by sweeping away snow, mechanism 2 can be kept away the Snowremoval of 1 lateral surface of condenser
The accumulated snow or frost accumulated of exempting from 1 lateral surface of condenser influence the heat exchange efficiency of condenser 1, to ensure that the heating effect of air-conditioning.This
The time resets the heating for restarting record after the completion of the time interval that mechanism of sweeping away snow in inventive embodiments 2 clears up was cleared up with last time
