Embodiment 1
[0037] like figure 1 As shown, the present invention provides an air conditioner outdoor unit, which includes a casing 1, a compressor 2 is arranged inside the casing 1, and at least one external condenser 3 is arranged outside the casing 1, and the compressor The machine 2 is connected with the external condenser 3 through a refrigerant pipeline.
[0038] By arranging at least one external condenser outside the outdoor unit casing, the wind energy in nature can be effectively utilized, and the external condenser can directly exchange heat with the outside air without entering the semi-closed air conditioning casing, which can reduce the The noise generated during the operation of the fan inside the casing, by using natural wind energy, reduces the dependence of the air conditioner on the internal flow field formed by the fan, that is, the internal flow field of the air conditioner can be appropriately weakened, which can also reduce the noise of air flow, thereby effectively ...
Embodiment 2
[0044] like figure 1 , this embodiment is a further improvement made on the basis of Embodiment 1. Preferably, at least one internal condenser 4 is provided inside the housing 1, and the compressor 2 and the internal condenser 4 It is also connected through the refrigerant pipeline. Through the setting of the internal condenser, it can cooperate with the external condenser to start the internal condenser especially when the external wind speed is small, so as to use the air flow inside the shell to perform heat exchange on the refrigerant, so as to complete the function and purpose of heat exchange .
[0045] like figure 1 , preferably, at least one fan 5 is further provided at a position corresponding to the internal condenser 4 inside the housing 1 . The airflow entering the inside of the casing can be driven by the fan provided inside the casing, so as to complete the heat exchange between the airflow and the internal condenser and increase the heat exchange efficiency.
Embodiment 3
[0047] This embodiment is a further improvement made on the basis of Embodiment 1 and / or 2, such as Figure 5 , preferably, two branches are connected to the exhaust port 21 of the compressor 2: a first condensed intake branch 61 and a second condensed intake branch 63, and the first condensed intake branch 61 One end of the external condenser 3 is connected to one end of the external condenser 3, and the other end of the external condenser 3 is connected to one end of the first condensing outlet branch 62;
[0048] One end of the second condensing air intake branch 63 is connected to one end of the internal condenser 4, and the other end of the internal condenser 4 is connected to one end of the second condensing air outlet branch 64;
[0049] The other end of the first condensing air outlet branch 62 is connected to the other end of the second condensing air outlet branch 64 , and is connected to the indoor unit of the air conditioner.
[0050] This is the specific pipeline...
