The aforementioned as well as other objects, features and advantages of the present disclosure will be more clear, by means of the following descriptions of the embodiments of the present disclosure with reference to the drawings, in which drawings:
The present disclosure is described as follows on the basis of the embodiments, but the present disclosure is not only limited to such embodiments. Several specific detailed portions are described in detail in the following detailed descriptions of the present disclosure. For a person skilled in the art, the present disclosure may also be fully understood without descriptions of such detailed portions. In order to avoid confusion of the essence of the present disclosure, detailed narrations are not made to the commonly known methods, processes, flow procedures, and elements.
In combination with the illustrations of
The air outlet 3 and the air inlet 2 are disposed on the same side surface of the housing 1, and after the embedded type air conditioner outdoor unit is embedded in the wall of the building, the side surface provided with the air outlet 3 and the air inlet 2 faces toward the outside of the building, so as to facilitate that the air inlet 2 introduces the air and the air outlet 3 expels the air after the heat exchange. The cross-flow fan 5 is used to introduce air by the air inlet 2 and expel the air which has exchanged heat with the heat exchanger 4 by the air outlet 3.
Relative to the technical solution that the air conditioner outdoor unit is suspended from the outer wall of the building in the related art, the embedded type air conditioner outdoor unit can prevent accidental damage and accidental loss caused by accidental fall-off.
After the embedded type air conditioner outdoor unit is embedded in the building, the vibration of the embedded outdoor unit is easily transferred to the indoor. The embedded outdoor unit of this embodiment adopts a cross-flow fan 5 with less noise and vibration to reduce the noise produced in the operation process of the embedded outdoor unit.
At least part of the side wall of the housing is sealed. The four vertical side walls of the housing are connected and sealed to reduce the noise and vibration propagated by the embedded air conditioner to the outside.
The embedded outdoor unit further comprises a compressor 7 mounted within the housing 1. When the air conditioner is in the cooling operation condition, the refrigerant compressed by the compressor 7 is conveyed to the heat exchanger 4 for heat radiation, and the refrigerant after heat radiation enters the indoor heat exchanger after throttling, the refrigerant is evaporated in the indoor heat exchanger to absorb the indoor heat, so as to reduce the indoor temperature.
In this embodiment, the air outlet 3 is located at the upper portion of the housing 1, and the air inlet 2 is located at the lower portion of the housing 1. Since the air with a higher temperature has a lower density, the provision of the air outlet 3 above the air inlet 2 facilitates the air flow.
In this embodiment, the heat exchanger 4 includes a first heat exchanger body 41 and a second heat exchanger body 42 arranged in a V shape with respect to the first heat exchanger body 41. The first heat exchanger body 41 and the second heat exchanger body 42 are both located between the air inlet 2 and the air outlet 3, and the V-shaped opening opposite to the side surface of the air inlet 2 and the air outlet 3.
The air introduced by the air inlet 2 flows toward the air outlet 3 along a substantially arc-shaped path, and the first heat exchanger body 41 and the second heat exchanger body 42 are arranged in a V shape, which is favorable for allowing that the first heat exchanger body 41 and the second heat exchanger body 42 are both substantially perpendicular to the path of the air flow, and thus increases a contact area of the air with the first heat exchanger body 41 and the second heat exchanger body 42.
Further, the first heat exchanger body 41 and the second heat exchanger body 42 are arranged in a V-shape, which is also favorable for making full use of the space within the housing 1 to make the structure of the embedded outdoor unit more compact.
The cross-flow fan 5 is disposed on a side of the second heat exchanger body 42 adjacent to the air outlet 3, and the embedded type air conditioner outdoor unit further comprises a volute 6 for guiding the airflow of the cross-flow fan 5 toward the air outlet. The cross-flow fan 5 is mount on a side of the second heat exchanger body 42 adjacent to the air outlet 3, and can also function to make full use of the space within the housing 1.
According to another aspect of the present application, the present embodiment further discloses an air conditioner, which is a VRF (Variable refrigerant Volume) air conditioner. The air conditioner comprises a plurality of indoor units and the aforementioned embedded type air conditioner outdoor unit, in which the plurality of indoor units communicate with the aforementioned embedded type air conditioner outdoor unit to allow the embedded type air conditioner outdoor unit to supply a refrigerant to the aforementioned plurality of indoor units.
The difference between this embodiment and the embodiment I lies in that: the air outlet 3 includes a first air outlet opening 31 provided on one side of the air inlet 2 and a second air outlet opening 32 provided on the other side of the air inlet 2.
The heat exchanger 4 includes a first heat exchanger body 41 and a second heat exchanger body 42 arranged in a V shape with respect to the first heat exchanger body 41. The second heat exchanger body 42 and the first heat exchanger body 41 are both located between the first air outlet opening 31 and the second air outlet opening 32, and the V-shaped opening faces towards the air inlet 2.
The air introduced by the air inlet 2 flows between the first heat exchanger body 41 and the second heat exchanger body 42 via the aforementioned V-shaped opening, and then flows to the first heat exchanger body 41 and the second heat exchanger body 42 respectively. After that, the air is expelled via the first air outlet opening 31 and the second air outlet opening 32 respectively.
The cross-flow fan includes a first cross-flow impeller 51 provided on a side of the first heat exchanger body 41 adjacent to the first air outlet opening 31, and the first cross-flow impeller 51 is used to expel via the first air outlet opening 31 the air introduced by the air inlet 2 after flowing through the first heat exchanger body 41.
The cross-flow fan includes a second cross-flow impeller 52 provided on a side of the second heat exchanger body 42 adjacent to the second air outlet opening 32, and the second cross-flow impeller 52 is used to expel via the second air outlet opening 32 the air introduced by the air inlet 2 after flowing through the second heat exchanger body 42.
The foregoing is intended only as a preferred embodiment of the present disclosure, but is not used for limiting the present disclosure, and for a person skilled in the art, the present disclosure may have various modifications and variations. Any amendment, equivalent replacement, improvement, and the like within the spirit and principles of the present disclosure should all be contained within the protection scope of the present disclosure.
