Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained on the premise of not making creative work, broadly falls into the scope of protection of the 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 provided with mechanism 2 of sweeping away snow, as shown in Fig. 2 snow removing control method comprises the following steps:
S1, heating mode opened by air-conditioning；
S2, mechanism of sweeping away snow enters standby mode；
S3, detection 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 every 2～5min and detects once；
S4, judges to run whether power is less than setting power value and electric current is less than setting electric current value, if run power being less than
Setting power value and electric current are less than setting electric current value then execution step s5；Otherwise, execution step s3；Specifically, in the present embodiment
When air-conditioning number is 1, setting power value is preferably 1631～1630w, and setting electric current is preferably 6.5～7.1a.
S5, controls mechanism 2 of sweeping away snow that the lateral surface of condenser 1 is cleared up；Execution step s2 is returned 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 power and current control mechanism 2 of sweeping away snow that runs adjusting clears up to the lateral surface of condenser 1, removes condenser 1 lateral surface
Accumulated snow or frost, it is to avoid the heat exchange efficiency of the accumulated snow of condenser 1 lateral surface or frost impact condenser 1, thus ensure that the system of air-conditioning
Thermal effect.When condenser 1 surface accumulated snow is serious, operation of air conditioner power and electric current all can reduce, according to the air-conditioning fortune detecting
Row power and current control are swept away snow the work of mechanism 2, can remove the accumulated snow of condenser 1 outer surface in time, avoid simultaneously
Sweep away snow mechanism 2 be constantly in working condition increase energy consumption.
Further, execution step: s11 before executing with step s2 after the execution of step s1 in the present embodiment, control is swept away snow
Mechanism 2 carries out pre-cleaning to the lateral surface of condenser 1.Specifically, sweep away snow mechanism 2 during pre-cleaning in the present embodiment to condensation
Device 1 returns to initial position after cleaning all inswept whole condenser 1 lateral surface every time, and the reciprocal number of times that cleans is 3～4 times.And
Chassis 3 heat tape operation setup duration is controlled to remove bottom after the completion of pre-cleaning while detecting operation of air conditioner power and electric current
Disk 3 and the accumulated snow of condenser 1 gap location.Heat tape operation setup duration is preferably 2～4min.Prevent accumulated snow on chassis 3 from getting over
To lead to chassis 3 to freeze more.Air-conditioning lateral surface of condenser 1 before opening heating mode may have accumulated snow, adopts
Mechanism 2 of sweeping away snow carries out pre-cleaning to the lateral surface of condenser 1, and condenser 1 can be made when starting to be maintained for good heat exchange effect
Rate is it is ensured that air-conditioning heating effect.
Further, execute following steps: s51 after the completion of being additionally included in step s5 in the present embodiment, control chassis 3 electricity to add
Tropical operation setup duration removes the accumulated snow on chassis 3 and condenser 1 gap location.Specifically, in step s51 in the present embodiment, electricity adds
