According to another aspect of the present application, there is provided a wall-hanging machine including the air supply assembly as described above.
In some embodiments, the wall-mounted unit includes a heat exchanger disposed in the air inlet channel and covering the inlet of the first air outlet channel and the inlet of the second air outlet channel.
The heat exchanger covers the inlet of the air outlet channel completely, so that the air flow after heat exchange is led out conveniently; wherein, the heat exchanger is equipped with two row at least structures, improves the heat transfer effect.
In some embodiments, the wall-hanging machine includes an air deflector 24, and the air deflector 24 is disposed at the outlet of the first air outlet channel and the outlet of the second air outlet channel.
The air deflector 24 is arranged in the air outlet channel to guide the direction of the exhausted airflow; the air deflectors 24 may be in the form of dual air deflectors 24 or may be single air deflectors 24.
As shown in fig. 3, the flow direction of the upper and lower air inlets and the upper and lower air outlets of the wall-mounted unit of the present application is schematically shown, a water pan 10 is disposed at the bottom of the evaporator 11, and a certain gap is required between the water pan 10 and the evaporator 11 when the water pan 10 is disposed, so as to ensure that the bottom air inlets are smoothly not blocked by the water pan 10. As shown in the evaporator 11 which is vertically arranged in the figures 1 and 2, the angle of the upper bending part and the lower bending part is not more than 45 degrees, so that the condensed water can be discharged to the water pan 10 along the fins, and water leakage is avoided. An air inlet channel with the interval of 15-50mm is arranged at the back of the evaporator 11, so that the top and the bottom of the air inlet channel can smoothly pass through the U-shaped tubes, and the heat exchange of the evaporator 11 is sufficient.
The two ends of the evaporator 11 are assembled with side plates 20, the U-shaped pipe expansion side plates 20 are fixed, and the evaporator 11 part is assembled on the bottom shell part 21 and is fixed left and right through screws; the evaporator 11 and the bottom shell component 21 are assembled on the panel body 22 together, and a positioning and limiting part is arranged between the evaporator side plate 20 and the panel body 22 to ensure an air inlet channel at the back of the evaporator 11; the evaporator 11 and the bottom shell component 21 are assembled on the panel body 22 together, and the upper part and the lower part are fixed by screws; the panel 23 and the air deflector 24 are assembled, and the display 5 is assembled on the panel 23 to form a whole machine.
During refrigeration, the upper cross-flow fan blade 2 is opened, the lower cross-flow fan blade 8 is closed, and only the upper air outlet 3 of the upper air duct 14 is opened, so that refrigeration is realized without blowing people; when heating, the lower cross-flow fan blade 8 is opened, the upper cross-flow fan blade 2 is closed, and only the lower air outlet 7 of the lower air duct 15 is opened, so that the heating can quickly fall to the ground.
The direction of the upper air outlet 3 is upward, the air deflector 24 is opened to guide the air upward, the air does not need to be lifted by the air deflector 24, and the problem of condensation of the air deflector 24 can be solved. The lower air outlet 7 is downward, the air deflector 24 is opened to guide the air downward, the air is not required to be pressed by the air deflector 24, and the problem of deformation sound of the heating air deflector 24 can be solved.
In order to prevent heat loss, an upper air duct heat preservation foam 12 is arranged at the back of an upper air duct 14 and a lower air duct 15 and at the upper front volute tongue 13 of the air port, and a lower air duct heat preservation foam 17 is arranged at the lower front volute tongue 16. The clearance between the volute tongue and the fan blade is 3-5mm, and the clearance between the fan blade and the air duct wall is 3-5mm at the lower back volute throat 18 and the upper back volute throat 19.
The upper air duct 14 and the lower air duct 15 can be opened simultaneously, and the rotating speed of the fan of the upper air duct 15 and the rotating speed of the fan of the lower air duct 15 are controlled according to the working condition of a room, so that the air output of the upper air outlet 3 and the air output of the lower air outlet 7 are automatically realized, and the air supply mode of the air conditioner is optimally matched with the working condition of the room. During refrigeration, the air volume of the lower air duct 15 is larger when the air conditioner is started, and the air volume of the lower air duct 15 is gradually reduced and the air volume of the upper air duct 14 is gradually increased along with the reduction of the room temperature.
The cross-flow fan blade air duct has better noise advantage than the centrifugal fan blade air duct. In addition, as the double cross-flow fan blades are used, compared with a single cross-flow air duct, the double cross-flow fan blades achieve the same capacity, and the diameter of the fan blades can be properly reduced to reduce the size of the whole machine. The diameter of the cross-flow fan blade of the existing 1.5P split machine is 98, and the diameter of the cross-flow fan blade refers to the 1PQ series shell fan blade 86.
Compared with a single cross-flow air duct, the double cross-flow fan blade achieves the same capacity, the air speed of the upper air outlet and the lower air outlet can be reduced, and the noise is reduced.
