Step 1 receives cleaning instruction；Cleaning instruction can be issued by manual control, can also independently be monitored by air conditioner
It is periodically issued after runing time.When cleaning indoor unit, needs to adjust wind deflector in advance, avoid blow-through human body.
Step 2, Frost formation process: control air conditioner operates in heating condition, into the Frost formation process of outdoor heat exchanger 15,
15 surface temperature of outdoor heat exchanger is lower than zero degree at this time, and the moisture in air is in its surface condensation；
It controls new blower 1 to run, blow to outdoor heat exchanger 15；Compare room temperature TIt is interiorWith outdoor temperature TOutside；
Work as TIt is interior> TOutsideWhen, such as winter, new blower 1 passes through outdoor fresh air pipe 6 from outdoor introducing fresh air.
Work as TIt is interior≤TOutsideWhen, such as summer, new blower 1 is by backwind tube 17 in the first indoor return air pipe 7 or second Room from interior
Introduce return air.
Meanwhile humidifying component 3 and running, increase the humidity that new blower 1 is blown, starting auxiliary temperature adjustment component 14 reduces fresh air
The temperature that machine 1 is blown accelerates the frosting of outdoor heat exchanger 15.
Step 3 detects frosting result.It can be by detecting the inner tube temperature of outdoor heat exchanger 15 or monitoring refrigerating operaton
Time judges frosting as a result, specifically, inner tube temperature reaches frosting lower limit temperature, when such as -18 DEG C~20 DEG C or refrigerating operaton
Between reach setting time, such as 180s, reach conditions above it is determined that frosting complete.
Step 4, defrost process: control air conditioner operates in cooling condition, into 15 defrost process of outdoor heat exchanger；?
When cleaning indoor unit, needs to adjust wind deflector in advance, avoid blow-through human body.
New blower 1 is run, and is blown to heat exchanger, is accelerated the defrost of heat exchanger, compare room temperature TIt is interiorWith outdoor temperature TOutside；
Work as TIt is interior≤TOutsideWhen, such as summer, new blower 1 passes through outdoor fresh air pipe 6 from outdoor introducing fresh air；
Work as TIt is interior> TOutsideWhen, in such as winter, new blower 1 is by backwind tube 17 in the first indoor return air pipe 7 or second Room from interior
Introduce return air.
Meanwhile starting auxiliary temperature adjustment component 14, improve the temperature that new blower 1 is blown.Defrost process can also pass through detection
Inner tube temperature or the judgement of monitoring heating operation time, specifically, inner tube temperature reaches 50 DEG C of defrost ceiling temperature or heating operation
360~600s of time.
In the clean method of the present embodiment, new blower can only frosting or defrost one of them during participate in work
Make, can also be involved in during frosting or defrost two.
