The number of the radial air outlets controlling the opening state of the two centrifugal fan sets 220 is the same, so that the air outlet directions of the two different centrifugal fan sets 220 can be controlled; if one of the centrifugal fan sets 220 discharges air in a single direction, the other centrifugal fan set 220 also discharges air in a single direction, and the direction of the air discharged in the single direction may be different. If one set of centrifugal fan unit 220 is used for simultaneously blowing air from the upper part and the lower part, the other set of centrifugal fan unit 220 is also used for simultaneously blowing air from the upper part and the lower part, so that multi-region air blowing and regional air volume control are realized.

Further, by controlling the opening and closing of the plurality of air inlets, the air inlet passage can be selected, and further, the air circulation path and the space between the opened radial air outlet and the plurality of air inlets outside the wall-mounted air conditioner 100, particularly the air circulation path and the space between the radial air outlet and the adjacent air inlets, can be selected.
Specifically, when the number of the radial air outlets in the open state of each centrifugal fan is 2, the radial air outlets on the upper side and the lower side of each centrifugal fan supply air simultaneously, all the air inlets are opened at the moment, so that the air of each air inlet and each air outlet can freely and sufficiently circulate, and the air is further supplied air more uniformly in all directions. When the quantity of the air outlet for the open mode of every centrifugal fan is 1, show that need supply air to local area, close the air intake of the air outlet homonymy that is supplying air this moment, the surplus air intake is opened, can make the air get into wall-hanging air conditioner 100 through the air intake of the air outlet relative side that is supplying air, avoid flowing back to wall-hanging air conditioner 100 in from the air intake that the air outlet blew off is adjacent immediately, lead to the unable abundant circulation of air in the environmental space further to regional air supply and select, the accurate control of multizone air supply effect and environmental space temperature has been strengthened.
Further, in the method for controlling the wall-mounted air conditioner 100, the wall-mounted air conditioner 100 may be controlled to implement the following air supply modes:
the first mode is as follows: controlling the air doors of the first radial air outlet 111 and the second radial air outlet 221 to be opened, and closing the air doors of the first radial lower air outlet 112 and the second radial lower air outlet 222; the first upper air outlet 622 of the housing and the second upper air outlet 628 of the housing are respectively used for exhausting air, so that the first lower air outlet of the housing and the second lower air outlet of the housing are not exhausted;
and a second mode: controlling the dampers of the first radial air outlet 111 and the second radial air outlet 221 to be closed, and controlling the dampers of the first radial lower air outlet 112 and the second radial lower air outlet 222 to be opened; so that the first upper housing outlet 622 and the second upper housing outlet 628 do not discharge air, and the first lower housing outlet and the second lower housing outlet respectively discharge air;
and a third mode: controlling the damper of the first radial air outlet 111 to be opened, the damper of the second radial air outlet 221 to be closed, the damper of the first radial lower air outlet 112 to be closed, and the damper of the second radial lower air outlet 222 to be opened; so that the first upper outlet 622 of the housing is exhausted, the second upper outlet 628 of the housing is not exhausted, the first lower outlet of the housing is not exhausted, and the second lower outlet of the housing is exhausted;
and a fourth mode: the damper of the first radial air outlet 111 is closed, the damper of the second radial air outlet 221 is opened, the damper of the first radial lower air outlet 112 is opened, and the damper of the second radial lower air outlet 222 is closed; the first upper outlet 622 of the housing does not output air, the second upper outlet 628 of the housing outputs air, the first lower outlet of the housing outputs air, and the second lower outlet of the housing does not output air.
