According to one embodiment of the utility model, the fan employs a centrifugal fan 15, which operates on the principle that an air flow axially flows into a rotating vane path of the centrifugal fan 15, is thrown toward the outer edge of the impeller by centrifugal force, and is discharged from the air outlet 11. The centrifugal fan has higher pressure coefficient and relatively low flow coefficient, and is divided into high pressure (15000-3000 Pa), medium pressure (3000-1000 Pa) and low pressure (less than 1000 Pa) according to the pressure, in this embodiment, the centrifugal fan 15 with low pressure is selected, but the pressure coefficient of the centrifugal fan 15 is still higher than that of a general axial flow fan, the pressure coefficient of the centrifugal fan 15 in this embodiment is enough to enable the air flow blown out from the centrifugal fan 15 to move upwards to a roof, and then the flow direction is changed, so that the blown air flow is prevented from being directly blown into a room, and the experience is more comfortable.

According to one embodiment of the utility model, the centrifugal fan 15 comprises an impeller, a shaft, a housing and a collector, the impeller being connected to the shaft, the bearing being connected to the housing by means of a lever or a mounting, the inner end surface of the housing (near an end surface of the housing) being connected to the collector.

During installation, whether the rotation direction of the blades is correct or not is noted, and the direction of air intake is consistent with the rotation direction of the impeller.

According to one embodiment of the utility model, the air flow axially flows into the rotating vane channel of the centrifugal fan 15 and is thrown against the outer edge of the impeller by centrifugal force, and in order to adapt to this characteristic of the centrifugal fan 15, the air outlet 11 on the housing needs to adapt to the edge of the impeller. In this embodiment, the air outlet 11 is rectangular, the width of the air outlet 11 is greater than or equal to the thickness of the centrifugal fan 15, and the length is greater than or equal to the diameter of the centrifugal fan 15, so that the air flow flowing out from the air outlet surface of the centrifugal fan 15 can reach the space outside the housing through the air outlet 11 as much as possible.

In another embodiment, the shape of the air outlet 11 formed on the air outlet surface of the housing may be an ellipse, and when the centrifugal fan 15 is perpendicularly projected onto the ellipse air outlet 11 along the radial direction, the perpendicular projection of the centrifugal fan 15 is completely wrapped by the ellipse air outlet 11.

Since the housing is relatively closed, when the centrifugal fan 15 is operated, the housing can be sucked through the air inlet because the air flows in a single direction to the outside of the housing, thereby causing a negative pressure state in the housing.

According to an embodiment of the present utility model, the centrifugal fan 15 is installed in the casing of the wall-mounted unit, the evaporator 14 and the condenser 13 are also installed in the casing, the evaporator 14 and the condenser 13 are communicated through the pipeline 4, and the evaporator 14 and the condenser 13 are also communicated with an external compressor through the pipeline 4, so that a loop is formed among the evaporator 14, the condenser 13 and the compressor. Specifically, the compressor is connected with the evaporator 14 and the condenser 13 through a pipeline 4, the pipeline 4 is tightly attached to the wall surface so as to be fixed by the wall surface, or the pipeline 4 is connected with a supporting column, the supporting column is connected with the wall surface and/or the floor, or the pipeline 4 has certain strength so that the pipeline 4 can be independent of the wall surface or the supporting column. In order to ensure that the positions of the evaporator 14 and the condenser 13 within the housing are relatively fixed, both the condenser 13 and the evaporator 14 have holes through which bolts pass, and the evaporator 14 and the condenser 13 are connected to the housing by bolts. In some examples, the pipe 4 is a copper pipe or an aluminum pipe, and the heat insulation layer is coated outside the pipe 4, so that heat of the refrigerant in the pipe 4 is not easy to diffuse. The pipe 4 accommodates a cooling medium, and the cooling medium can flow in the pipe 4. It will be appreciated that the specific number of the pipes 4 in this embodiment may be set according to actual needs, and in general, two pipes 4 may be provided and connected to the inlet and the outlet of the compressor, respectively.
